[SOLVED] OpenGL video playback slow on radeonhd

Hi,
My video playback is very slow when using OpenGL output, both in VLC and mplayer.  When using the x11 driver, the playback is normal in VLC, but in mplayer there is a problem with the aspect: the picture does not scale.
I have a Radeon mobility X1600 and an up to date Arch64. glxinfo report direct rendering, and glxgears gives about 215 FPS at the default window size (if I make it smaller, then it boosts to about 700). I don't use fglrx, since I can't put the laptop in suspend to ram mode with it - rather, I can but then I can't wake it up
Any ideas?
Thanks!
Eduardo

Hi,
Thanks for the link!
I realized that the offical Xorg ati driver also has support for my card. I just switched to it, and the mplayer problems are solved Incidentally, the glxgears count went up to about 1450. The suspend to ram also works, so I think I'll stick to this driver.
Thanks again!
Regards,
Eduardo

  • ITunes 11 HD video playback slow/choppy/stutter/skipping in OSX

    Hi guys,
    I'm running iTunes 11.0.1 in OS 10.8.2 on my 2.66 GHzm, 8 GB RAM MacBook Pro and playback in HD (1080p) movies/TV shows in iTunes is slow, choppy, stuttering and skipping. Can't seem to fix it. Any help would be greatly appreciated!
    Thanks!

    I was having this same problem, and found one cause.
    I have an extensive library on a Drobo FS.  None of the AppleTV's in the house have any problem streaming full 1080p from it, but my new iMac does.  Choppy / laggy video play.  Movies and TV shows right from the iTunes store.  I can have 3 TV's streaming, and even a 4th laptop, all streaming from the iMac iTunes using the Drobo.  They all have zero issues.  No lag, no choppy, nothing.  iMac has the issue even when nothing else is running.  Every time.
    BTW, it's happend on my old iMac and the brand new one, both with iTunes 11.
    I was told to try setting up a second account on my iMac, and try playing video there.  It worked.  No problems at all.  Weird.
    So I started looking at differences between the new account, and my standard.  I'd already made sure nothing unusual was running, and no processor hogs (not that anything short of Handbrake at full settings has come close to pegging out the processers on the new box).  I found one thing, that made a difference.  I had Timemachine backups, going to the same Drobo FS (though a different partition) turned on on the iMac.
    Timemachine was running the whole time, and didn't impact any other streaming from the same machine, but it did make iTunes video playback of 1080p movies skip like my 6 year old daughter on the iMac.  I turned it off.... no more skipping.  I've watched 5 TV shows and 2 movies on that account, and not had another single incident.
    Obviously, there is still a problem.  The iMac and Drobo have enough bandwidth that they can do all the work at the same time (or I'd be seeing the problem on the other devices while streaming), but they are not playing well together on the same account.  I've also checked the throughput to the Drobo FS from the iMac... way more than necessary.  If it were a read / write thing on the Drobo, then I'd expect other devices to see the issue when I'm watching something on the iMac that is skipping, but there was still no skipping on any other device at that same time...
    But, as I said, I found the root cause in my case.  I can turn off Timemachine backups while I'm watching a movie on the iMac, or I can move where I write the Timemachine backups to (going to try this over the weekend to be sure it works).  If moving the Timemachine backup to a different drive doesn't work, it's a bigger problem.
    I'd really love to see Apple fix this and the issue where I have to turn iTunes on in 32bit mode when using an external library (of it gives the funky quicktime error until you delete and readd the movie).
    Hope this helps some of you, if not all.

  • Video playback slow and audio drop out after render

    Hi
    I have downloaded a trial version of After Effects from the cc,
    Problem is everytime I render ou,t the video playback is slow and the audio drops out
    This happens with AVI or Quicktime files.
    Using a Intel i5 quad core, 8 gig of ram 250 gig ssd.laptop
    Render/export in Premire pro is fine.
    Can any one help.
    Regards Phil Green
    Blue Room Media.

    It sounds like you might be hitting the space bar in hopes of getting real time playback.  Sorry, but AE doesn't work like that, because it does totally different things from an editing application like Premiere.
    And if you've downloaded the tryout version, you really ought to learn how AE works... and a short description is "it doesn't work intuitively".  You can frustrate yourself in a hurry.
    But this can really help;

  • My Many Irritations (story) and a New Solved Problem (video playback)

    This topic is just going to ramble through the many things that have irritated me about my iPod since the purchase only three weeks ago. Don't get me wrong, though, I still love the thing. For the most serious problems, check out Numbers 3 and 11.
    Lets see... where to begin...
    I originally had no interest in the iPod, but some time after the unveiling of the fifth generation's new capabilities a friend of mine started talking about it quite a lot. And so, some time in early November, my hype for the video iPod had grown greatly. I downloaded Videora iPod converter and started converting music videos like crazy.
    By the time December rolled in I had successfully converted almost all of my 150 or so music videos and imported them into iTunes. With Christmas coming up I was wondering if I should just ask for it as a gift, but impatience set in and I bought it on the fifth of December, and have greatly enjoyed it since.
    Sounds peachy, but there's a fair bit that I left out.
    Number 1. I love viewing movie trailers on Apple's website. But with the recent update to the quicktime software, it was required to get the updated version. With that came iTunes, a program that was at the time unwanted and an irratation.
    Number 2. Videora iPod Converter has it's fair share of bugs. While I successfully converted many a video with it, I found it would 100% of the time fail to convert files of the .wmv format (Windows Media). As well, I would later find a more serious problem.
    Number 3. On the first day of using the iPod I had a serious error. I had been watching videos just fine all day, and the iPod was working perfectly. I then chose a video to play and inexplicably the iPod froze. These are the symptoms: black screen, backlight on, no responce from controls.
    Tired, as it was the end of the day, I was unwilling to go to the computer room and attempt to find a solution online. And so, I gambled that the backlight would drain the battery and hoped that upon a recharge, everything would be fine. As the backlight was illuminating my bedroom, I put the iPod in it's sleeve to dim it a bit and went to sleep.
    As you can imagine, this was kind of scary. I was afraid that I had bricked my iPod on it's first day.
    In the morning, the battery had died and I was able to recharge it by syncing it with my computer. After charging, I tried a few videos and then tried the offending video. Again it froze, but this time I was confident that the backlight would drain the battery and it would be fine.
    I then looked at the folder wherin I had saved the converted video. Among all my other videos was the offending one. I played it in Quicktime 7, and everything was fine until I realized the length of the video was double what it should be. After what should be the end of the music video came two minutes of a white screen. The file size was also abnormally large, compared to the other videos.
    It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played. Now, when converting batches of videos with Videora, I scan the file-sizes to see if any are abnormally large; after all, using the same settings on a batch of similar in length videos should produce files of similar size.
    It occurs to me now that the method for resetting the iPod might have worked as an alternative to draining the battery.
    Number 4. I should mention that the battery life on this thing was (for me) unexpectedly low when playing videos. I'm not saying that mine is defective or anything, but I just found that the battery runs down pretty quick when playing videos; quicker than I had thought it might. Not a big problem, though.
    Number 5. In a search to find something to convert my .wmv videos to an iPod compatible format I found the ImToo converter. It works quite well, but the trial version is limited to videos of five minutes or less in length. I'm considering paying for the full version, but if someone knows of another reliable .wmv converter, I'd be glad to try that. For now, ImToo is good enough as most music videos are less than five minutes long, but I do have some other videos in the .wmv format that I would like to transcode.
    Number 6. In mid December I went out of town for three days. Of course, I brought along my new favorite portable media player. Not surprisingly, the battery soon ran low and I was without my computer to recharge it. So I went out to a store and bought Apple's official USB Power Adapter. I thought it was kind of expensive, especially considering that they used to be BUNDLED with the older iPod models, but I was happy to find I would now be able to charge my iPod. Wrong. Something that was not made obvious to me by the package description (if it is even mentioned there) is that the darn thing needs the USB cable that came with the iPod. It does not come with one, and so if all you have is a wall socket, the USB Power Adapter, and an iPod, you're screwed. Unless it's the iPod shuffle, which apparantly is the only thing that works with the USB Power Adapter out of the box. As far as portability goes, I feel this hurts. I would have liked to keep my USB cable attached to my computer. After all, it is a pain to get to the back of my computer and keep plugging it in or unplugging it.
    Number 7. I'm rather irritated with certain aspects of the iPod's interface considering music videos and regular song files. I spent a good amount of time adding artist and album tags to all of my music videos. These tags make sorting the videos in iTunes much easier.
    First, the iPod's interface does not allow for the search of videos through album tags, but does through artist tags.
    Second, going to Music>Albums> gives a long, cluttered list of Albums because of all of my music videos and one-hit songs that belong to only one album each.
    I suppose there is a workaround.
    Number 8. I recently bought another accessory for my iPod. The LOGiiX Amplified Fold-Up Speakers. A very attractive and portable set of speakers for the iPod. It comes with a little stand that holds the iPod in place, and works off of either 4 AAA Batteries or AC Power. Yet again, this is a product that DOES NOT come with the power adapter. Now, I think I MAY have one somewhere in my house... perhaps the power adapter that CAME WITH my SONY MD that is being replaced with the iPod will work....
    Oh, and that little clip-on stand I mentioned? I expect it to be lost soon because when I fold up my portable speakers there is no way to clip the stand onto the outside of the speakers.
    Now, as far as portability goes, I have to carry with me (at the most) seven things: the iPod, the headphones, the USB connector, the USB power adapter, the fold-up speakers, the little stand, and an AC power adapter.
    Number 9. Minor irritation in my control of the clickwheel. After this long, I still accidentally select the wrong thing, and often take a fair time to get the highlight where I want. Meh, this one I'll figure out eventually.
    Number 10. There was something irritating about entirely forgetting my login for my Apple ID and having to create this brand new one for today.
    Number 11. Just today, I have come across a problem with the video not playing. I watched one video just fine, went to the Videos>Movies> tab and, as mentioned above, accidentally highlighted a video I did not wish to play and hit the Select button. Normally when this happens I wait until the video has loaded - when the screen goes black and the white Play symbol appears in the top left. But this time, I immediately hit the Menu button to go back to the Movies tab. The video's loading was interrupted and I went back to the Movies tab.
    Now, when I select and play ANY video, after a noticable but short wait the screen goes black, another noticably longer wait and the play symbol appears, and then a black screen for a few seconds and the iPod skips ahead to the next video, which behaves in the exact same way.
    I have powered down the iPod using the method of holding the pause button, but the problem persits.
    My music videos can be played as songs by finding them under the Music tab, but no videos play as videos.
    I am not at my home computer, and so running iPod updater or just trying to sync is not an option right now.
    I will soon try to reset the iPod using the method described on Apple's support website.
    EDIT Okay, the reset did the trick. Videos are playing fine now. I still want to share my iPod story, so I'll leave this here, but have changed it from being a question. Below are the instructions I followed for the reset.
    RESETTING THE IPOD
    1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
    2. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.

    Nice Rant session:
    "It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played. Now, when converting batches of videos with Videora, I scan the file-sizes to see if any are abnormally large; after all, using the same settings on a batch of similar in length videos should produce files of similar size."
    What did you expect for freeware? Nice effort but because it's free everyone thinks it's a gem. It's not. This web site has been flooded with questions that should be directed at the authors website. Video conversion and editing is not for the beginner. Sounds to me that you have a bunch of badly converted videos that are causing a lot of problems. Videora problems:
    Known Bugs
    Audio/Video sync
    Problem - Output files can be out-of-sync. While no set pattern has been established, it seems to be more frequent with input files of 23.976 fps, non-DVD rips, and WMV/MPG filetypes.
    Workaround solutions - Try the custom option '-async 1'. If the disconnect gradually increases over time, setting 29.97 fps sometimes gets rid of the problem regardless of the input fps. You can also use AviSynth to assume the FPS and have the audio sync to that. If it's a sudden disconnect, check your VOB Cell settings in DVD Decrypter settings per this thread. Otherwise, test with an AviSynth script per the DaProphecy's method in the FAQ. For non-DVD files, PSPVideo 9 may be a good short-term solution until the converter stabilizes some more or try something like AviDemux.
    Audio track not getting picked up
    Problem - The IFO stream rip is fine, but the converted file has no sound. The debug info showed to audio track getting picked up. The most obvious case with this is the Madagascar DVD.
    Workaround solution ideas - Test with an AviSynth script per the DaProphecy's method in the FAQ (untested). Use a different DVD ripper.
    Program doesn't start (.NET issue?)
    Problem - Converter errors upon starting with an extended dump.
    Solution ideas - Update .NET framework (in all languages you're using!) to most recent solution. Clean out registry. Neither of these have worked for some.
    Progress meter incorrect
    Problem - During transcodes, the progress meter can be incorrect; thus, transcoding continues after the meter hits 100% and time remaining is zero. People have been seeing this more often with VOB files and/or the H.264 codec.
    Workaround - Figure out the length of your movie in seconds and compare that to the 'Processed' field. A 2-hour movie will not finish until Processed hits 7200 seconds.
    Artifacts (bad video quality) in darker scenes
    Problem - Scenes with darker background colors tend to have more artifacts (blocked video). It's much more obvious on the iPod, so this may be an Apple firmware problem.
    Workaround ideas - Use a VBR setting (FQ->VBR, two-pass A->VBR) to improve video quality. The custom option '-mbd 2' might help.
    Desktop icon
    Problem - When installing, the desktop icon does not appear/stick when using lower color setups.
    Workarounds - Select a 32-bit color scheme in your desktop settings, or change the icon in the shortcut.
    Profile changes don't always stick
    Problem - If you make a change to a profile, click apply, and immediately trancdoe with that profile, the transcode might not use the new settings.
    Workarounds - Once you click apply, swtich to another profile and back again to make sure the change is still there. If that doesn't work, create a new profile.
    Can only install/use with admin rights
    Problem - There have been reports of non-admin users not being able to use the converter.
    Workarounds - Separate installs or give all users admin rights.
    Who in their right mind would use a program that has these many critical bugs to convert files for the IPOD. People who are cheap, kids with no money and people who are just plain gullably.
    A little research and downloading a trial from this site would have solved your video problems early on;
    http://www.divmm.com/
    The 5th Gen IPOD was designed to support video content that was purchased on the ITunes web site. For everything else, you are on your own.

  • Video playback slow when adding titles

    I'm using Premiere Elements 10 on iMac with 4 GB RAM and i7 processor, and I noticed a weird behaviour with the playback function.
    Usually it works fine but, if I add a title into a video track (EDIT->New Item->Title), the playback becomes very slow and sometimes it is totally frozen. I can "scrub" the timeline without any problem, but it seems that the "play" button stops working. It happens with simple video clips too.
    Have you ever experienced similar issues on a Mac?
    Thank you.
    BC

    Bruno,
    Great news!
    Rendering is often mis-understood, as with some footage/Projects, and some editing operations, it is not really necessary for adequately smooth playback. I often have SD Projects, where I will never bother to Render anything, as it is smooth enough, without Rendering. However, and especially when doing Keyframed Effect animation, I might Render a section of my Timeline many dozen times, to test with the best playback. With HD material/Projects, especially if one does not have a "killer" computer, Rendering might be more necessary, and more often. This ARTICLE goes into more detail.
    Good luck, and happy editing,

  • Music puts video in slow motion

    I love the fact that I can get online here and seek help. IT has always helped me before-so hopefully I will get lucky now. I am using Imovie 9-- am new user and so far have learned how to use it-compared to the later versions-- a few learning curves but not bad.
    My problem is when I import a sound effect or music clip- the video portion goes into slow motion. Quite simply- when I remove the sound effect-it resumes to regular speed? what am I doing wrong or how to I just add the music and have the video play as is?
    THanks so much!

    python2-pillow (2.6.0-1 -> 2.6.1-1)
    Since the 24/10 there is an error message in systemd's journal:

    There is no output when I start smplayer from the console. In vlc there is no problem. In smplayer the video playback slows down when I maximize the window using maximize button of the window itself. When I resize the window to its maximum manually or use the full screen button of smplayer, then there is no problem. It appears to be a problem with smplayer, because in mplayer there is no problem when I maximize with the window using the maximize button.
    I tried nvidia-304xx yesterday, but that didn't help.

  • Slow video playback

    Hello,
    I previously had no problems playing videos in iTunes. Recently, however, video playback becomes choppy about 10 seconds in, while audio remains fine. This happens both with my own ripped videos and with iTunes Store videos, at 100% view (i.e., not fullscreen or anything). Looking at Activity Monitor, iTunes begins to eat up 90-105% CPU.
    I only have a few apps running (e.g., Camino, iChat, Mail), and everything is responsive until iTunes starts chugging away, at which point my whole system slows down. Can anyone help shed some light on what is going on?

    I've been having the same problem on my G4. I created a second user account and noticed that videos play perfectly there, just not in my normal account. I'm now trying to troubleshoot from there to see if it's some third party thing or widget or something that is the cause. Maybe someone else could try the same thing - create another account and see if that solves the problem - then go back and try troubleshooting their regular account. This seems like it could be a solvable problem to me at this point. Please post your results.

  • Slow/unresponsive video playback, media pending, after CC'14 October update

    Encountering a strange issue after the October update. It's a project carried over from the previous CC'14 version, nothing crazy, about an 18 minute timeline of video/.mov clips straight off a JVC GY-HM600U with simple RGB curves/masks on some clips, some Prores422 clips of graphics exported out of After Effects, a couple nested sequences featuring simple text w/ cross dissolves, and a lower 3rd Quicktime with RGB+Alpha. There are some linked AE comps in the project but not in the sequence. Ran fine before update. Here's my system, obviously no CUDA so Mercury Playback is software only:
    Upon opening the project everything is fine, playback is smooth, scrubbing from beginning to end no problem. After a period of time, 10-15 minutes? Suddenly video playback hangs up, with audio continuing to play after . Opening a clip in the Source window displays the Media Pending thumbnail, after 15 seconds it seems to find the media but again it's only a still frame with video hanging up. Then audio seems to hang up and I can't do anything. I can still manipulate the UI but scrubbing through the timeline is completely unresponsive, pressing play does nothing.
    Quitting the program seems to freeze it, the window closes but it stays lit up in my dock and shows Application Not Responding, causing me to force quit.
    A system reboot yesterday seemed to clear the issue up for the remainder of the work day but it's back today. Not sure where the issue is coming from, but seems like some kind of memory leak or something similar since it seems to be a gradual degradation in performance. I'll have to roll back to a previous version to finish up this project until things are fixed.

    Hello,
    Many thanks for your very long reply and your interest in my problems.
    I shall try to answer you :
    - 1) OS :  Windows 7 64 bits Pro SP1, french,
                     Version : 6.1.7601.18247 (Win7RTM)
                     Framework.NET : 4.0.30319.18408 built by : FX451RTMGREL)
                     DirectX : 11.0,
                     OpenGL : 6.1.7600.16385 (Win7_rtm.090713-1255).
    - 2) Yes the media pending goes away but after a couple of minutes (one
    year ago I was using PP CS6 and Encore CS6, I never had this problem
    even with very long files),
    - 3) Yes my GPU driver is updated (Nvidia GeForce 332.21 dated 12/19/2014).
    I never had thiese problems with PP CS6 + Encore CS6 and my projects
    built with these PP ans Encore version were with the same structure and
    length (in PP CS6 : sequences up to 45 minutes, in Encore CS6 chapters
    up to the same time).
    The difference between are in my hardware :
    - the RAM was upgraded from 12 GB to 24 GB,
    - the CPU was overclocked from 3,2 GHz (default) to 3,88 GHz).
    - 4) I shall try up to the disk burn to check if the problem is just due
    to display of "animated buttons".
    I hope my answer will be usefull for you.
    Regards,
    Jacques Gourier.

  • Slow video playback in Photoshop Elements 11

    Playback of videos directly in Photoshop Elements Organizer is very slow. Video is stuttering.
    Playing the same video outside of PSE11 with Windows Media Player is much better. Video plays without any stuttering.
    Looks like the internal video player of PSE11 is very poor and provides slow performance.
    What can I do do have the same video performance with the PSE11 player as I have with WMP.
    I use Windows 7 64 Bit (8 GB RAM) with a Intel Core i3 (2330). This CPU has enough power to playback HD or Full-HD videos without any stuttering!!!
    Why can't the internal play of PSE11 Organizer play my videos without stuttering - like WMP 12.0.7601.18150 does?
    Regards,
    Dodson65

    The videos I use are created with different devices.
    I have HD videos taken with a Pentax DSLR and I have Full-HD videos taken with a Windows Phone 8 device.
    Both playback on my Laptop without any stottering with different software. I checked WMP and VLC. Even when using my Laptop with energy-saving profile these videos can be played without stottering.
    When I playback the videos in PSE11 Organizer I don't want to edit them - just playback. So why should the internal player behave different? I agree with you - this might be different when I playback the videos in Premiere Elements 11 (as this is a video editing software). But when using Photoshop Elements 11 I want to be able to playback videos in the same performance as I can do with WMP or VLC. If Photoshop Elements 11 can't do that - why? The organizer of PSE11 is not an editor. It should be able to playback videos the same way (with the same performance) as other players on my laptop.
    Can you please explain this sentence: "Have you started a Premiere Elements project yet that uses this video's specs? This will often trigger Premiere Elements to download the necessary components for interpretting the video." Is there anything I can do to improve video playback performance?

  • Re: Satelite M70 - Video playback really slow and dtrange metalic noise

    Hi
    I have a Satelite M70 laptop and a few days now I realise that the video (youtube and any sort of videos) playback speed is really slow, slow motion (my interenet speed is fine)
    and there is a really creepy kind metal noise when the video is playing.... u cant hear anything just that noise.
    Also when i open a file or a menu in windows u get theis king of metalic noise
    I have checked the video and audio codecs and are the latest
    btw: I can hear audio files from media player just fine. It seems this happens only with videos
    Any suggestions cause i cant see any videos!!!!!

    I was 100% sure you will post this.
    Online playback speed is always different. I have fastest 16000 DSL line and I have noticed the same on my M70 and brand new Satellite P300. Sometimes is youtube or some livestream video perfect and sometimes audio and video don't match together or the video playback is like in slow-motion.
    I have also latest drivers and codecs preinstalled on both machines. There is one interesting thing-this slow-motion happen when the HDD led is blinking and when the HDD is running. Please play a little bit with this stuff and watch carefully how it works.
    About sound and speakers is not easy to say if they are defective or not. The fact is that sound on headphones works perfectly is evidence that sound card or sound driver is not the problem.
    I really don't know what to say but I believe the speakers don't work properly.
    What do you think?

  • Slow video playback in very high resolution X11

    Hi everyone. I write this msg for ask your eternal knowledgement.
    I have a very huge system (i7 3820 LGA2011, 8Gb quad channel, Gigabyte x79-up5-wifi, AMD HD5870 2Gb Eyefinity 6, etc) running Arch on it. The OS is updated. The Arch config is very minimal, using Fluxbox as WM and VLC and Mplayer to playback videos. The video driver is the latest stable Catalyst (13.4) and so on. I got connected six HD screens seted to a resolution of 1366x768. These screens are managed with xrandr, adjusted for considering the bezel compensation, using xrand --output MONITOR --pos X+BEZELxY+BEZEL.
    When i play a video with mplayer (using the gl video driver) the movie shows very well and smooth, but when i pan the video all over de virtual screen (4194x1583 aprox), the movie shows very choppy.
    The strange fact is the Conky reports shows me an 5% of CPU usage, so the system performance are not the problem.
    The mplayer flags that i use to play this video are plenty, being the threads=4, gl:ati-hack and -root the most important.
    If anyone can give me a hint to solve this issue, i would be very grateful.
    thx in advance.

    The videos I use are created with different devices.
    I have HD videos taken with a Pentax DSLR and I have Full-HD videos taken with a Windows Phone 8 device.
    Both playback on my Laptop without any stottering with different software. I checked WMP and VLC. Even when using my Laptop with energy-saving profile these videos can be played without stottering.
    When I playback the videos in PSE11 Organizer I don't want to edit them - just playback. So why should the internal player behave different? I agree with you - this might be different when I playback the videos in Premiere Elements 11 (as this is a video editing software). But when using Photoshop Elements 11 I want to be able to playback videos in the same performance as I can do with WMP or VLC. If Photoshop Elements 11 can't do that - why? The organizer of PSE11 is not an editor. It should be able to playback videos the same way (with the same performance) as other players on my laptop.
    Can you please explain this sentence: "Have you started a Premiere Elements project yet that uses this video's specs? This will often trigger Premiere Elements to download the necessary components for interpretting the video." Is there anything I can do to improve video playback performance?

  • Itunes 9 – Backup doesn't function, Video playback is now slow, Requires a

    TOPIC: iTunes 9 – Backup doesn't function, Video playback is now slow, Requires a reboot to find the super drive when changing CDs or DVDs.
    iTunes 9 has been difficult to say the least. We have a very large Video and TV library, backups are critical. When starting a backup to disc, we put in the blank DVD and the software reports that it will take XX (39 in this case) discs. After the first DVD ejects and the second blank is inserted, iTunes hangs.
    Second: Watching programs on hulu.com the video drops frames and a very jerky playback experience sometimes including audio. iTunes 9 now works the same way, gone are the smooth video and audio. An authorized computer in our house can no longer play back any movies or TV that are located on the MacMini.
    Third and most disturbing: Since the iTunes 9 upgrade, when listening to a CD on the Apple and it completes, if you want to listen to another one – it requires a Restart of the computer. It no longer knows that there is a super drive attached to the computer. After the restart, it works just fine for one use, CD or DVD and then you must restart to listen or watch another one. Using the super drive for data or programs works correctly and no problems experienced.
    I want to be clear - none of these problems were happening before the forced upgrade to iTunes 9. After reading several posts, I don't want to sync my iPod Classic (80GB) for fear of what it will do to it.
    The above is happening on a MacMini, G4 PPC, 1GB RAM, 80GB internal, 2 Terabyte external, OS-X 10.4 fully patched for operating system and applications.
    We need to know when the 9.1 bug fix will be released? As long as it took to convert our library to 9.0, we don't want to try and back convert to version 8.x. In our case that would take feeding 221 backup DVDs and repurchase of several 9.0 only, episodes.
    WE need the bug fix and fast!

    I am running iTunes9 on WinXP, and I also cannot get it to back up. It either hangs on the "initializing" phase, or it thinks that my blank disks aren't blank and keeps spitting them out.
    Also, I've brought this up before, by why MUST we back up to DVD? Why can't we backup to a folder location (such as network share or external HD)? DVD backup is slow, problematic, and wasteful. Especially if it fails, and you need to throw out the disks it's already burned, and will not resume where it left off before the failure.
    For a company that's usually known for its design and "it just works" philosophy, how can you keep making such a broken, buggy product? Here's a thought, before cramming more crap into iTunes, let's just get it working as advertised for once? That would be nice.

  • Recording with audio playback slowed down 65% what speed do I need to speed the video back up to to get it into real time?

    Ive recorded a test video with audio/music playback slowed down 65% what speed do I need to speed the video back up to to get it into "real" time?
    If I'd slowed the audio playback down 50% I would make the video 100% faster.
    If I'd slowed the audio playback down 100% I would make the video 200% faster.
    So its obviously somewhere inbetween speeding up by 100-200%
    Sorry but its melting my brain today and I cant remember the calculation.
    thanks

    hey all
    Thanks for the advise on this. I will explain a little more what am have/am intending to do.
    I have used Audacity to slow the song down (Effect>Change Tempo)
    Audacity will allow me slow the original song down by up to 99% (Or anything in-between up to 3 decimal places)
    Unfortunately I am working to a time restraint of 12 minutes per clip (as my DSLR will only allow up to a 12 minute clip).
    The song at normal speed is 4 minutes long.
    Originally I slowed the audio down by 50% (Making the audio 8 minutes long), lip synced to it using a rasta blaster and recorded the video using my DSLR at 720p 50fps.
    I then imported the video and audio I had been lip syncing to into FCPX.
    I sped up the video by x2 (equivalent to speeding it up 200%)
    Retime>Fast 2X
    Layered the PROPER normal speed audio back over the top and all was fine.
    Test video complete.
    (You can ignore the 65% slowed down audio I mentioned earlier if you like, that was just an example of a slower than 50% audio test)
    Firstly what I really want to do is to be able to slow the AUDIO down as much as possible (But still within the restraints of only being able to adjust FCPX retiming within a whole 1 percentage in the final video edit), but have the AUDIO of the song as near to/under 12 minutes as possible.
    I will then re-record the video again to this new slowed down audio.
    Secondly I will speed up the video from 12 minutes to 4 minutes.
    Thirdly I will layer the correct 100% Normal AUDIO on top.
    The FINISHED video should then look like everyone is wizzing around at high speed but the guitar playing/lyrics look like they are being played/sung at the normal speed.
    Whatever happens (due to the constraints of FCPX) I need the calculations to work so that FCPX is retimed exactly to a whole 1% for the final video to sync up correctly.
    So what I need to know in a nut shell is:-
    What calculation do I use to work out the percentage to slow a 4 minute song down to a 12 minute song?
    What calculation do I use to work out the percentage of how much I need to then speed the 12 minute video up to turn it back into a 4 minute video?
    My mind is melting
