Playing high bitrate videos on 5800XM

What is the major limitation(in other words,bottleneck) of 5800XM to play high bitrate video?
Clock rate of CPU,cache capacity, reading speed of SD card or other things?
I use FormatFactory to convent the videos with video-bitrate 1600Kbps and audio-bitrate 192Kbps
(lower than that, the difference can be observed easily...)
It can play but be stopped after 30s to several min. while the audio is still playing.
I use the SD card provided by Nokia that its reading speed is around 16-18MB/s

I would have thought that the bottleneck is the memory card. A class 4 card can transfer at roughly 4MB/s, not 15-16MB/s, and that's a theoretical maximum burst rate, not sustained rate.
A higher bitrate means less "brutal" compression and therefore less work for the CPU to do in order to decompress it.

What model do i need to play high bitrate bluray 1080p movies

Hi
I want to buy a macbook pro.
As the topic says: What model do i need to play high bitrate bluray 1080p movies without noticeable losses of frames?

if they are with DRM you need the hdmi cable if your tv have hdmi that is
if they are not DRM then you can use the component cable if your tv have component
if they are not DRM then you can use the composite cable if your tv have composite
top is best
button is worst in terms of quality

IMovie with High Bitrate Video A7 or A8X?

I plan to purchase an iPad Air 2 or iPad Mini Retina for editing 1080p MP4 video. I believe the bitrate will be around 20-30Mbps.
Does anyone know if this is possible with an A7 or A8X? What kind of performance could I expect?
I'm not so worried about final rendering wait times, but I'd like to have smoothness during previewing in the timeline, and minimal UI lag.
Also, I'm a bit torn between the Air and the Mini screen size. Does the Mini show exactly the same amount of content in iMovie as the Air, just smaller?
You might be wondering why I'd even be considering the iPad Mini 2... it's just so much cheaper and I love the form factor!
Thanks in advance for any help.

Thank you for replying!
I would be transferring video files over WiFi via an app for my camera. But I'll also get the USB to lightning adapter for an audio device. I believe you can attach a card reader to that as well.
I mentioned imovie, but I'm thinking I'll probably be using Pinnacle Studio. The UI is more complex, and I suppose it has me leaning towards an Air1 or Air2.
The Air2's screen really blew me away at the store. I have this dream of working outside. Maybe this is the device to do this. But the Air1 also has a good display and refurb options are mighty tempting...

Viewing High Definition Videos

iMac 20 inch 2 GHZ
Is it worth paying extra to rent high definition videos vs. standard definition to view on my iMacs 20 inch screen. Is there a noticeable difference in viewing quality? I usually watch videos from about 8 feet away.

Thank you for taking the time to respond.
However, I did not mean to ask if the iMac was capable of playing high definition videos comfortably.
I meant to get opinions on whether high definition videos from iTunes are suppose to look noticeably better than standard definition videos on the iMacs 20 inch screen at a distance about 8 feet. I am thinking that the difference in quality is not noticeable because of the size of the screen and viewing distance.
I rented an HD version of the new James Bond flick and can't see much of a difference in quality between it and a standard definition video of The Office. I don't know if it is just because I am not a videophile or because of the size of the screen and viewing distance? I realize that tells me if it is worth paying extra, but I still would like to know your opinions on the difference in quality that you see.
I apologize for the confusion.

Unable to play 1080p HD videos smoothly? "Possible Solutions".

Have you read many similar issues of people running into problems viewing 1080p HD or higher videos once they upgraded to OS X Lion, Mavericks or Yosemite? Have you read that once they reverted back to Snow Leopard everything played fine again? That may be true, but such a headache! Before going through all of that hassle, you may first want to try something else before ruling out the latest operating system is the main cause for your mac slowing down. Your RAM cache could be the main culprit.
After exhausting all research and options I thought were available, I decided to finally call Apple tech support. Since I thought this was an issue after upgrading to operating systems beyond Snow Leopard, after hearing many others experiencing the same issue after upgrading to mountain lion or mavericks, I assumed it was the new OS X causing this slow down. Anyhow, I got connected with a tech support for free based on this issue happening after the OS X upgrades as far as I was aware of. We walked through a "screen share" on how I can free up RAM usage that might help speed things up a bit and help video display in 1080p work more smoothly; sure enough this helped a lot!
So if you're reading this and have experienced similar issues, there's no need for upgrading your ram if possible "just yet", and no need to revert back to snow leopard either "just yet". The cache in your library folders is more than likely the culprit, causing cluttered extra unnecessary things to run in the background and doing a "P RAM reset" and clearing out 2 different library cache folders on your system (should) clear things up like new again. If not, then you may need to upgrade your ram or have the graphics card or processor looked at b a technician to make sure those are running smoothly.
First I want to thank Kim the tech support representative for walking me through this, it helped a lot!
Here are the steps you'll first need to take to clear your ram and cache.
1. need to shut down your computer
2.hold down the option/command/P/R keys before you start up your macbook pro again. You'll see it restart and hear the bong chime again, then release all keys knowing you reset your RAM.
3. click on your desktop, then go to the GO menu for your system, then click on "Computer" on the drop down menu, followed by "Library" then "Cache" folder. select all and empty all contents of that folder into the trash.
4.Go to your "Finder" menu Hold down "option" key then scroll over to "Go" menu, you'll see the hidden library folder. Click on that library folder, then click on the cache folder, select all and empty all contents in that folder to the trash.
5. You'll need to reset your computer again before you can empty all contents in the trash.
6. try watching 1080p or larger videos on youtube or on your desktop again, you should be able to watch those high resolution videos again just fine, unless your RAM size is too low, then you may need a RAM upgrade, or you may want to have your graphics card looked at to see if everything is working properly on it.

I think my settings are fine... and I've waited for the entire trailer to finish downloading so that I'm not streaming it. It's playing a local file. Did you play it on your iMac or MBP?
If some MBPs are able to play the clip and others aren't perhaps the issue is with my hardware.
ewww,
I did consider that the trailer itself is defective... I noticed that the bitrate on that particular trailer is quite a bit higher than normal at around 12mbits/s, compared to the norm of around 7-8. However to my knowledge at least, 12mbits/s should not be outside the realm of possibility on these machines.
In any case, I continue to anticipate the results from other MBP owners. I'd like to try to ascertain whether this is a software/firmware issue or whether something is amiss with my hardware.

Does the low bitrate of x-fi 5.1 pro affect playback quality of higher bitrates?

I needed a 5.1 sound card for my laptop, and this was the only one I could afford used -- so far Im pretty satisfied, it works for cheap.
but I need to know if its important to save up for a better one right away --
I was concerned that since it only supports 44.8 and 96kbps that higher encoded audio like 128kbps and greater may not play back at the same quality they were recorded -- this is important because I ONLY use digital audio -- I have no analog -- videos are blu-ray rips, audio is FLAC or high encoded MP3, no cds, dvds, physical blu-rays.
so the encoding is often 128kbps or higher. sometimes even 196.
right now im keeping it until I can afford better regardless -- but is playback of these higher bitrates lower quality since it is being output at only 44.8 or 96?
just wondering, been finding it hard to get a straight simple answer to this. lots of people insist I never have audio play back at higher than 44.8 or 96, but I find that impossible since LOTS of my audio is encoded either lossless or at a higher rate.

So are you only getting sound out of the front center channel? I have this issue only from certain audio sources, such as YouTube videos, where all front right and left channel audio is put out through the center channel only. Are you not getting sounds from the front channels when using any type of media (mp3, games, DVDs)?
The only other reasons I was having issues like this were as follows: I hadn't checked the mixer settings yet in the windows and creative control panels to ensure volume levels were set correctly for all channels; I hadn't yet set my speakers to 5. sound (although this only affected the rear channels).
Let me know what you find. Also, have you tried the utility in the Creative control panel that lets you click each speaker to test it yet?

Advice on buying camera for stills and high speed video

Hello video pros,
I'm a music composer who occasionally dallies with some simple photographic and video work. I'm looking for some advice re picking up a camera to make some simple videos, but with the highest quality I can get with consumer grade gear.
I am pretty much ruling out consumer grade camcorders for two reasons: One is that I want to be able to shoot high quality stills and make stop motion videos from very high res stills. The other is that I don't need audio recording at all because the video will always be just to accompany music - simple music videos basically. So I'm much more interested in the recent mid range point-and-shoot bridge cameras with full HD video modes rather than camcorders - they seem to cover more realistically the range of things I want to do.
My main question is regarding shooting at higher frame rates than 30 fps. I'd like to shoot video at a minimum of 60 fps (or higher) to then playback at 25 fps to get that smooth, slightly dreamy motion effect. There are a few cameras out there that offer high speed video modes, but most are nothing more than a gimmick because the res is so low that the resulting video is unusable. However a few cameras now seem to hit a sweet spot, offering 60 fps recording at HD res, and also 120 fps at 640x480 which (at a pinch) is usable, at least for stuff destined for simple web use.
The cameras I've narrowed it down to so far seem to be the Nikon Coolpix P500, the Panasonic Lumix DMC-FZ40 and possibly the Fujifilm HS20 EXR. I also was vaguely interested in the Casio Exilim HS cameras, but they seem to only offer high speed video modes that are pointless - 1000 fps at a completely useless low res, and 120 fps only at 640x480. The others I listed seem to offer at least 60 fps at some kind of HD res, so I'm assuming that with these cameras I could shoot decent looking video which would then play back with that slightly hyper real slow-mo effect when I import into FCP at 25 fps. Is this correct? Or is it the case that when they say HD video @ 60fps, it's some kind of interlaced mode which means you can't play back at a slower frame rate to get smooth slow motion?
The other thing I've noted is that all of these cameras do record HD video, but it's always compressed in H264 format. I understand that this puts a serious limitation on how much post-processing you can do to the video afterwards. Highly compressed video will begin to show image artefacts very quickly when you apply effects as opposed to higher quality (bigger file size) video compression. But I think I can live with that given that for the stuff I want to make, it will just be simply edited and only lightly graded. However, of the cameras I'm looking at, the Lumix also records in a format called AVCHD which (I think) does full HD at 17 Mbps. Does this mean that it's basic video quality is significantly better than the other choices? That said, from the specs it's unclear if it actually allows shooting at higher frame rates which you can slow down at playback.. the way it describes 60fps mode makes it sound like it's just interlacing so you don't actually get a higher number of images per second to then be able to play back at a lower frame rate. This for me might rule it out because I really want the creative effect of high speed video, even if it's only the subtle effect of 60 fps slowed down to 25.
So in summary, I'm looking for a camera capable of creative shooting (high quality stills to make stop motion videos, usable-quality HD video along with at least some degree of high speed video at a resolution that is still usable) to make interesting and artistic footage to accompany music. The destination medium is the web, so even though I'd like to get the best quality raw material to work with, the final destination is not exactly a cinema screen. As a pro in a related industry, I'm all too aware of the pointlessness of buying outlandishly over-specced gear that is far beyond your level of expertise. So I want to keep it simple and realistic, budget-wise, given the level I'm at. Nothing more than say $800 US. A seriously high end camera would be wasted on me, and I think it would be wiser to invest in useful accessories like a steadicam merlin and decent tripod rather than blow loads of cash on a camera far beyond my skill level.
Apologies for the long post, any and all advice would be very welcome and appreciated! And feel free to correct me if my assumptions are wrong, and suggest any gear that I should consider looking at.

Hi, thanks for your input. I'm aware of the fact that my question is a bit OT, but I'm just looking for input from people with more experience and broader information in this area than I have myself.. I know people are here to talk about FCP, but I'm betting many editors and film makers who work with FCP will have more insight in this area than I do.
I've been reading every review I can find at dpreview, and also am watching as many test video examples I can find on the internet, mostly on vimeo because the ones on youtube look pretty awful. I just am reaching out to get some actual experience and advice from people who might give me pointers on what to look out for.
As for 60fps not being fast enough, I know what you're saying. But for me, even 60 fps slowed down to 25 fps on playback is enough of an interesting effect, as long as the actual quality of the footage looks good to start off with. I like the subtle effect of slightly slower than real motion when it's real, bona-fide high frame rate slowed down. Artificially created slow-mo using plug ins looks cheesy to me, and the gimmicky super high frame rates of cameras like the casio exilim (where the resolution looks like a mobile phone video from ten years ago) are completely useless.
I've seen lots of examples on vimeo of stuff shot with DSLRs from Canon and Nikon at 60fps and then played back at 25 or 24, and it looks plenty nice enough for what I'm after. But am I kidding myself that I'd get anything near as nice with the price range I'm looking at?

Why isn't my high definition video converting to standard definition?

What I'm describing here, I've successfully accomplished many, many times using Premiere Pro CS5 and now Premiere Pro CS6. Now, for the first time ever, it's not working and I'm completely baffled. (This is a high-end Windows 7 64-Bit machine with 16GB RAM running Premiere Pro CS6.)
Here's a basic summary of my workflow. Nothing out of the ordinary here.
1. I shoot my video using a high definition camcorder (the same one I've been working with for the past year or two.
2. I import my high definition video into a 1920x1080 sequence in Premiere Pro CS6.
3. I edit my sequence until I'm happy.
4. I enter and name my Encore chapter markers in the sequence.
5. I create my Encore project and import the sequence as a timeline and set up my menus and such.
6. I build my Encore project, first into a standard definition DVD image file (so I can later burn SD-DVDs) and then build it again into a high definition Blu-ray image file (so I can later burn Blu-rays).
The Blu-ray burn is turning out just fine.
But the video in the DVD burn is all black. I can jump around from chapter to chapter and I can hear the sound, but the video doesn't show up!
I tried this a couple times thinking that maybe Encore just messed up the SD-DVD creation process but I got the same result each time. When I preview the project in Encore, it all looks just right.
So I figured, okay, something's not working when I import the sequence.
I went back to Premiere Pro thinking I'd just export my 1920x1080 sequence into a widescreen standard definition AVI and create a new sequence just for the standard definition DVD.
The exported AVI is black as well!!
I don't get it. Why on earth won't my high definition video convert properly to standard definition?
The high definition sequence looks completely normal in Premiere Pro. What could I possibly be overlooking??
One final note. Just as another test, I copied and pasted the sequence in Premier Pro, truncated it to a couple minutes (the full sequence is 90 minutes long), and exported to a widescreen AVI again.
It just finished, I tried playing it back in Windows, and it, too, is all black, sound but no video.
Like I said, this is nothing new for me. I've done it countless times with other projects. I could really use some assistance with this one.

So I exported my completed high definition sequence to an MP4 and re-imported back into Premiere Pro. Right-clicked it and created a sequence from the clip. Then I imported my chapters from the old sequence into the new one.
I returned to Encore, modified my project to work off the newly created sequence (what a pain having to recreate all the scene links) and voila, it had no trouble making a DVD this time.
So I guess I'll get out of the bad habit of my old routine and create a sequence the "right" way from now on. Funny how we get used to doing something one way and stop thinking outside the box after a while.
Jim, I don't see how that's necessary. As long as I create an Encore project based on a good high definition sequence, I have never had to do anything other than have Encore build a standard definition DVD based on the high definition sequences. It has always done the conversion for me and produced really good DVDs. Once I create a DVD image that I'm satisfied with, I simply have Encore build a Blu-ray image using the exact same project, and that works perfectly as well. I suppose I may be missing something here but it all works and works well, so I don't see a reason to create two projects when one works well.
On a separate note, is it just me or doesn't everybody think it's high time that Adobe offer a feature to import markers from one sequence into another. I can do it automatically but I have to use a macro that I created separate and apart from Premiere Pro. For that matter, I think Encore should also offer a feature to remap all scene links to a new sequence instead of forcing me to fix them one by one myself.
Anyway, thanks to all of you for pointing me in the right direction!

Cannot Find File - Convert higher bitrate songs to 128kb AAC on an iPhone??

I ran out of room on my iPhone 3G, so I checked the "Convert higher bitrate songs to 128kb AAC" option. I had already made an 'iPhone' playlist as the only playlist synched with iTunes, and the playlist reduced its iPhone footprint by roughly 25%. It worked well except for several songs that "could not be found" by iTunes. These are all songs for which I have the CD, and play perfectly in iTunes (and on the iPhone before the conversion).
I have tried deleting the songs from my 'iPhone' playlist, iTunes, and my hard drive and reinstalling from the CD (first to iTunes then to the iPhone playlist) - ALL with reboots and permission repairs between reinstalls. These 13 songs seem to be impossible to convert, despite several other songs from the same CDs converting perfectly!!!
After each attempt, iTunes goes through and re-evaluates the gaps, which takes time. This is not a problem, I just note it for diagnostic purposes.
How do I resolve this perplexing and vexing conversion problem? The songs ARE on the hard drive, and iTunes CAN find them (because they play in other playlists and played before the conversion) they just do not seem to convert.
Help!

Everything is up to date, except for the security patch released yesterday. That is on the list for a 'today task' but I have not gotten to it yet.

High def videos vs. Low def videos on iPad

Hi, everybody. I bought a video, and accidentally bought it in high def, when I meant to get low def. It downloaded and played just fine, so apparently my iPad does support high def, but I'm wondering whether it was worth the extra money.
I've heard that when you buy a high def video from the app store, you get both it and the low def version. So my question is, how do I find the low def version to get a look at it before I buy another video?

Please see: iTunes Store: Viewing and downloading HD content on iPad which should clear this up for you.

Steve

High bitrate and old devices

Hi
I did not find this information inside the Encore manual or FAQs here... So it's just a question ir order to know if I can work safety this way....
Suppose I have a 20 minutes of video and need to burn it in a DVD. When exporting to the MPEG-2 (for Premiere or even in Encore with Adobe Dynamic Link), in order to get the maximum quality I can, I specify almost the maximum bitrate... So, VBR Pass 2, and Minimum = 8, Target = 8,5 and Maximum = 9.
This will get a biggest file, but even thinking it's only a 20 minutes, it will get inside the 4.7 GB of DVD without problem.
Suppose also I do the same thinking, but now for Blu-Rays (using almost the biggest bitrate value).
The question is:
Will this video have an incompatiblity with older devices? Older DVD Players or older Blu-Ray players?
Or this is not a problem for any device? Any device can interpret and work with higher bitrates?
Thank you very much
Gustavo.

Hi Gustavo.
For the DVD, Ann has said it all above.
For the Blu-ray though, I would always encode to Profile 1.0/1.1 bitrate limitations, and not Profile 2 simply because there are still a lot of P1 players out there and the increased bitrates for P2 may well cause problems on P1 players - indeed, when encoding for replication Scenarist & DoStudio will both tell you that you may have compatibility issues if the bitrate is set for the much higher P2 limits.
Profile 2 can handle up to around 62-65Mbps, whereas Profile 1/1.1 is down at around 40Mbps.
You should rarely need to go anywhere near these levels though - typical bitrates for high definition video are as follows:
MPEG-4 (AVC/264) - minimum = 4 (not an absolute, but lower than this will not be acceptable in quality unless encoding a slideshow)
                               Typical = 16
                               Maximum = 40
SMPTE VC-1         - minimum = 4 (not an absolute, but lower than this will not be acceptable in quality unless encoding a slideshow)
                               Typical = 18
                               Maximum = 40
MPEG-2                - minimum = 4 (not an absolute, but lower than this will not be acceptable in quality unless encoding a slideshow)
                               Typical = 24
                               Maximum = 40
I would avoid going near the maximum levels though, as you must also take into account audio, popup menus, subtitling & overheads as well as "burst peak" rates - what you set as maximum is often not the same as what you actually end up with for all sorts of reasons.
Hope this helps

High bitrate on wireless mu

I purchased the Wireless Music device about a month ago and it has worked flawlessly out of the box for me. I have just run into the first snag, however. I have been ripping all my music as relati'vely high bitrate MP3's with no problem. I wanted as clean a sound as I could get with my classical CD's so I burned them as lossless WMA's. Unfortunately, they won't play. I get a long hourglass on the remote and then no sound. The track is listed under 'Now Playing' but nothing comes out of the speakers. Do I have to settle for half the bitrate to play my classical music?

I still haven't heard back on this topic. Most of my music is fine at 320, but I would like some music (especially the classical) to be played in lossless format. Hoping for a solution.

Gstreamer fails to play *some* .mp4 videos

Gstreamer is no longer able to play *some* .mp4 videos. Just until recently
(possibly update) that worked fine for me. I will appretiate any help with resolving this problem.
Videos concerning were downloaded from Youtube via the Firefox DownloadHelper,
so I suspect some of them to use some non-standard format feature. Also
ffmpeg-ing videos to other or same format works and converted videos can be
played by Gstreamer without problems.
This is the only download video I was able to confirm Gstreamer can still play:
http://www.youtube.com/watch?v=T0UbcngpDkk
It fails for almost every other, e.g.:

How to play back AVCHD video files without jerkiness result?

Hi all, I have an iMac 27" 3.06Ghz as well as the new MacBook Air 13 1.86Ghz, and both have 4GB of RAM. When I tried to play back AVCHD video files (*.mts) recorded from my Canon HF200 HD camcorder, the play back is always jerky and choppy. I have tried various software like Perian for QT, VLC, MPlayer Extended, all have the same result. However, I can play back other 1080p files like MKV and MOV just fine.
Is the jerkiness problem that I am seeing due to underpowered hardware? or is it I am not using the correct software? Note that I am not trying to edit HD videos, I just want to be able to play them back smoothly. I can play the same files on Windows 7 natively without any issues.
I am curious if any of you have the same problem. Please help!
Thanks in advance.

Swaza,
Just thought I would jump in and share some experiences with .tod and .mod files.
I too have the JVC GZ-HD7 camera and I can confirm that the new version of the MPEG-SC 1.93beta will open and convert .tod to .mov for use with iMovieHD. I am not sure that the files can be used with iMovie08 since I have not tried, but it will work in iMovieHD just like any other qt or .mov file import.
Also, you can use the QTpro plugin that came with the camera (should be on the CD as the only MAC software available.) This will allow you to open the files in QT and convert them to any other format needed. This plugin unfortunately does not allow QTpro to open the older .mod files of previous JVC cameras. For that you can still use MPEG-SC.
In my experiences over the last few weeks, having mistakenly dumped all of my footage onto my hdd as I used to do with my older JVC cameras, I am now stuck with 3 hours of footage on my HDD as .tod files. I have been struggling to find the right blend of codec type, compression amount, fps, and quality to convert these files in an acceptable resolution (1920x1080 full - another mistake since iMovie08 will not import this quality but will import the 1440 CBR mode.) Converting these files is a nightmare and has become a stain on my otherwise wonderfu lexperience with this new camera (It is an awesome camera despite what negative stuff the "Canon fanboys" are saying!) It takes an unbelievably long time to convert. And you will find that when viewing these files in QT either as .tod or even after converting to .mov, they will be jerky and stutter. I believe this is more to the fact that the files are just really huge. Playback inside of iMovie06HD was perfect for me though.
Hope this helps out and I hope others may offer solutions as to what codecs they are using and what settings they are using to keep the quality as high as possible when converting these files.

How to export a complex Keynote to high quality video for DVD?

I have had dozens of attempts to turn a complex Keynote into a high quality video.
Either they turn out disappointiingly way low res
or they are very choppy with half the transitions gone
or they Cannot make the video at all
HELP.
I need to turn this project in to my client today.

If you use the DVD export in Keynote 3 with a self playing movie, the quality will be fine...just don't trust what you see on your mac screen, play it on a DVD player to check the quality. I did a test a while back and it was only the pauses that looked bad.
Read about it here:

pay close attention to what I complain about...it's just the slide pauses, not the normal motion playback, which means selfplaying stuff looks pretty decent (though never as good as the original, but that's the fault of the DVD format, not Apple).
