Choppy/slow HD videos on QuickTime

I'm trying to watch a mp4 (720p I think it is) on my Mac OSX 10.5.8 Desktop (It is Power PC, if that matters). In the past, lesser quality vids have run great on it, but not HD ones. I've tried both quicktime and VLC but in both cases it does not work. VLC is a bit better, but it is still incredibly choppy and slow. On Quicktime, it is so bad it's completely unwatchable. The sound will continue while the picture is frozen, and finally it will skip ahead like three minutes only to freeze again. Can I make this viddeo run smoother on my computer without paying money, or is it hopeless?

Your system may be underpowered for the file in question. MP4 file containers can either be MPEG4/AAC or H.264/AAC. The H.264 (MPEG-4/AVC) format requires more CPU power than the MPEG-4 codec. Further, depending on the settings used to encode an H.264 file, these power requirements may be further increased. (For instance, a 30/29.97 FPS file requires more playback power than a 24/23.96 FPS file. Basically what usually happens is that QT 7 drops frames during playback if it cannot keep up. Usually this simply produces a jerky rather than smooth playback of action. However, in sever cases (i.e., high data rates, high frame rates, high key frame frequency, CPU intensive entropy setting, etc,), this can ultimately cause the video to "freeze."

Possibly. The normal approach would be to re-compress the file to MPEG-4 and/or H.264 with a smaller display size and lower data rate. Unfortunately, this may take a lot of time (in the case of H.264) on your system and/or reduce the overall quality of video playback depending on your particular work flow.

  • Choppy/Slow streamed videos on both Firefox and Chrome

    I have a 2010 Macbook Pro that was recently turned off for two weeks while I was on vacation. When I turned it back on and tried to watch videos online (youtube, Netflix, streamed videos) the videos are choppy and slow to load. This was never a problem before turning of the computer for the two weeks. I have tried both Google Chrome and Firefox and the problem happens on both. When viewing the Activity Monitor while attempting to watch the videos the CPU usage is fine for the first 20 seconds or so and then Chrome or Firefox take on 80-90-over 100% of the CPU usage, a majority of the usage is from the system (in red) and the videos become untwatchable. I have uninstalled and reinstalled both browsers and have disbaled all the extensions. I have uninstalled and reinstalled Silverlight for Netflix and have uninstalled all unused versions of Adobe Flash player. There are no problems with video when I watch a DVD. Help! I want to watch videos again

    having same problem since mac os x 10.6 upgrade, but was never issue prior... have tried everything i can think of, new flash players, reinstalling players, reboots of computer and router... to no avail. since this was never an issue for me prior to upgrading to Mac OS X (10.6.8), i believe its the os software.

  • Videos played via internet are so slow and choppy, SLOW Firefox

    Was wondering if anyone knew for sure the reason why videos/movie trailers played thru either Safari or Firefox are extremely slow and choppy on my G5 imac or G4 iBook laptop. Not sure if the outdated processors cant handle the flash embedded videos Youtube, Quicktime and other sites post, but it is really annoying not to be able to watch anything smoothly. Even if i let the entire video load (if it is a quicktime), then play it, it still is very choppy. The audio plays fine, but the video never keeps up. I have a 6mb DSL connection, so that cant be the problem. Any video I play via my iPod Touch (aside from flash videos it cant play) they are as smooth as can be (And that is via a wireless connection). Which makes me think it is a processor issue. Any thoughts?
    Anyone have any suggestions on how I can remedy this situation? (aside from buying a new computer...)
    PLUS, does anyone notice how slow Firefox is, or is it just me? Seems like even when i type in this form field, time lags as the letters show up. I have the latest version, and it is so slow. Switching tabs takes time... Reading and accessing RSS fields in the Feed Sidebar plug in is really slow...
    Any ideas would be greatly appreciated! Thanks!

    QuickTime is designed to "drop" frames during playback when the machine can't keep up with the video data rate (audio continues normally). This may appear as a "stutter" during playback on an older machine.
    It's not based on the Internet connection speed.
    Apple movie trailers use the newer (2005) H.264 video codec and they demand a high CPU (Intel is best). You should get better performance on your G5 than on the G4.
    Videos encoded using Flash will be equally difficult to view on older machines

  • Choppy Video w/Quicktime Hardware Acceleration Unchecked

    In every other application (PowerDVD, WinDVD. TMPG DVD Author, etc.) videos play smoothly without enabling hardware acceleration. In iTunes (7.6.1.9), I must enable the hardware acceleration checkbox in Quicktime to allow smooth playback, However, this compromises video quality. The gamma curve seems messed up, black levels are too high and music videos have a general "washed out" appearance. Playing the same video in Quicktime itself is perfectly smooth with hardware acceleration unchecked and the video quality looks great. Since iTunes uses the Quicktime engine, I do not understand why this is happening?
    I've put in a support request to Apple but no resolution, just the usual suggestions to download the latest nVidia drivers (done), uninstall/reinstall (done), etc. Same results on fast Ultra320 SCSI drive or Serial ATA drive.

    I would try rolling back to an older version of flash. I think some if the recent releases of flash have been ultra buggy. I have quite a powerful laptop cpu/gpu and recent versions of flash are a bit choppy for me too. This forum has had a huge increase in posters with problems. Video should pose no problem for a computer even if it is a few years old.

  • Itunes choppy, slow since upgrading to 10.x

    Ever since I upgraded to version 10.x or the latest as of this date, when I want to listen to itunes its horribly choppy, slows down and buzzes during playback.   I've updated quicktime to version 7.x still didn't help.  It doesn't appear to be CPU or Memory related as the system is running at CPU levels of 25% utilized and memory is about 50%. 
    Any help would be appreciated

    Hi and Welcome to Apple Discussions...
    Try emptying the cache and reset Safari and see if that helps.
    From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
    From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
    If you are running Safari in 64 bit mode, try running in 32-bit mode instead. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.

  • Problems with exporting audio music video to QuickTime

    In iMovie I made this audio music video, combining music with photos and audiovisual clips. In iMovie I muted the original sounds of the photos and audiovisual clips. Yet after exporting the audio music video to QuickTime, parts of the original soundtrack can still be heard, some of it in the right place, some are scattered out at random. I have exported audio music videos from iMovie to QuickTime before - consisting of music and audiovisual clips - and then I had not theses issues. Can somebody explain to me what I can do to mute the original soundtrack in QuickTime? I don't want this original soundtrack to spoil the audio music video when I upload it to Youtube.
    Thanks in advance

    There is a bug in iMovie 09 that produces weird audio artifacts when you use speed changes (fast or slow motion) that do not conform to the preset tick marks of 25%, 50%, 100%, 200%, 400%, 800%, etc.
    If you are using custom speed percentages like 58% or 139%, change them to one of the presets, and that will fix the sound.

  • New Sequence Question - for slow motion video

    Hi,
    I'm a very new user of Premier.  I've recently had issues with choppy playback of my preview videos.  After much research I believe the issue was down to two things.  Firstly my sequence did not match my input clip, I had it set to my desired output.  Secondly, I was editing video across my network, rather than bringing it locally to my PC.  I've fixed the latter issue by copying video files to my local machine and then moving them back onto the network once I've finished editing.
    The advice out there essentially seems to be to match your sequence to your primary input video.  I've done that and it helps.  However, it's raised a big question for me.  My input video is from a GoPro and is at 1080p 50fps.  I ultimately want my output video to be slowed down to 25fps (resulting in a constant slow motion effect throughout the entire sequence). 
    If my sequence settings are set to match the input clip (50fps) and I slow the video down by 50%, will that result in an unsmooth video?  My basic understanding is that if I slow 50fps video down by 50% then Premier will have to double the amount of frames.  Where as previously, if I slowed it down by 50% Premier had enough frames to play with as the output video was 25fps.
    Hopefully my question makes sense!  Any advice on what the best approach is?  Or is this a complete non-issue when it comes to exporting the video (providing I export to a 25fps formart)?
    Thanks,

    I think you said it OK, you are just missing the right words to do what you want. Let's walk through this for you, and for others that might read it later.
    If you take a 50 frame per second video and put it into a sequence created from it, then slow it down 50% it doubles up each frame to achieve slow motion. Not what you want.
    If you take a 50 frame per second video and put it into a 25 fps sequence, it drops half the frames to play at normal speed. Not what you want.
    What you want to do is interpret the 50 fps video to 25 fps, then drop it into a 25 fps sequence. Each frame will play at 25 fps and generally be smooth as silk.
    I don't have any 50 fps clips handy, but here are examples of taking 60 fps to 30 fps. (Excuse the idiot way that we Americans do things. Our 30 is actually 29.97 etc)
    First, right click on the clip in the Project Panel, select Modify, and Interpret Footage. Then change the 50 to 25 - similar to this image:

  • Slow Youtube videos

    Using Safari 3.0.4 / OsX 10.4.11 / G4 400 1GB RAM / Rage 128 Video card 16mb Ram/ Broadband ADSL 2 Internet / Realtek USB Wireless card Vs 1.5.1a
    When playing videos, Safari becomes very very slow, the videos also become very slow and eventually stop. We have tried using Firefox and the same thing happens. Have tried with no other applications open and the same happens.
    Other computers on the network are fine, PC and Mac.
    Something is obviously wrong with the G4 400 - is it just too slow - video card - USB bus?
    Quicktime and other video files on the computer play fine with the Quicktime Player
    Christo

    400 Mhz is the bare minimum to run 10.4, so unless you have maxed out with at least 1 GB of RAM and have ample hard drive space, you're pushing your luck. You're also not running the latest "stable" version of Safari, v3.1.2, but the reason why is a mystery. Have you tried downloading Camino and watching YouTube videos with it to see if it's an improvement?
    Do you have other applications running when you're trying to watch YouTube videos? If so, can you quit any or all of them to see if that makes a difference? When was the last time you performed system maintenance on this Mac (cleaning up the cache, etc.)? If it wasn't recently, try this:
    1. Quit Safari if it's running.
    2. Go to ~/Library/Caches/com.apple.Safari and delete the entire contents of that folder. Do the same for ~/Library/Caches/Safari.
    3. Go to ~/Library/Safari and delete any of these files you find there:
    • Downloads.plist
    • Form Values
    • History.plist
    • Last Session.plist
    • WebpageIcons.db
    4. Open System Preferences > Network > Configure > TCP/IP and enter these two numbers in the DNS Servers field:
    208.67.222.222
    208.67.220.220
    click Apply Now, quit System Preferences and restart Safari to see if things have improved.

  • Is there a way to speed up or slow down video clips in iMovie using the iPad?

    Is there a way to speed up or slow down video clips using iMovie on the iPad? I do not have an Apple computer...just the iPad.

    No.
    There are other apps that can to time shifting, or speed effects.
    iMovie cannot.

  • Blank, now garbled video in quicktime osx

    I have a Samsung SC-MX20 camera, play perfectly in QuickTime Player 7.6 but the video is blank (black) in quicktime X, up until I upgraded to 10.6.4. Now the video is garbled. Funny thing is it plays fine on my (older) imac. Computer is a macbook (non firewire), late 2008 model.
    Thoughts?
    Rick

    I'm having the same problem (no video when I open a MP4 or other video in QuickTime Player). However, I can view videos in iTunes. Candydrop's list is mostly my list too, but I don't have: AC3MovieImport.component or Perian.component.
    I do have these that CandyDrop doesn't:
    AppleMPEG2Codec.component
    DivX Decoder.component
    FLV.component
    So to sum up, this is my list:
    AppleIntermediateCodec.component
    AppleMPEG2Codec.component
    DivX Decoder.component
    Flip4Mac WMV Advanced.component
    Flip4Mac WMV Export.component
    Flip4Mac WMV Import.component
    FLV.component
    Any ideas? This is a huge problem for me and I have to have it solved by the end of the day! Ack!

  • Slow-motion videos do not play as edited (fps) on Mac

    Hi all,
    I just received my iPhone 6 yesterday, and have been playing with the slow-motion video feature. I moved a few over to my computer using Image Capture, and they played fine in their slow-motion, 240 fps. However, the problem is that it doesn't play the video as it was edited on my iPhone (parts of it sped up, and parts of it slowed down). It plays the whole video in slow-motion, which can be a little annoying watching an entire video.
    Thanks, all, for any help!
    P.S. I'm using OS X version 10.9.4

    In Firefox, click Tools>Add-ons. Make sure the Shockwave Flash plugin is enabled and "Always activated".
    If that fails, see: How to perform a "clean install" of Flash Player in Mac OS X  in the Adobe Forums. That will clear out the pluigins and allow a fresh install with the new plugin.

  • Please help. When exporting a 720p video using Quicktime Conversion in FCP it saves some extra temporary files to my computer. The file is called ICMMultiPassStorage. This file gets so large that eventually the program and exporting process crashes.

    Please help. When exporting a 720p video using Quicktime Conversion in FCP it saves some extra temporary files to my computer. The temporary file it saves is called ICMMultiPassStorage. This file gets so large that eventually the program and exporting process crashes. I have been able to locate the file using GrandPerspective and close out of FCP to delete it. But when I try exporting the movie again it creates the ICMMultiPassStorage file again. I have made sure my scratch disks are set to my external hard drive so I know that isn't the issue. How do I fix this problem so these temporary files are not being stored on my internal hard drive instead of my external?Thanks!

    Try exporting the timeline "using current settings" via Make QuickTime Movie, then submit that clip to Compressor for the transcode. This should be faster and less painful.

  • Slow motion video. By design or bug?

    If I create a slow mo video and share it by iMessage the recipient views it correctly but if I view it in the thread it plays at normal speed throughout.
    Is this a bug or by design?

    I'll take this feature request to product management.  I can't say if or when such support will be available.  In the meantime, as a workaround use iMovie to export your video with the slo-mo effect to your Camera Roll so Revel can import the processed version.

  • Record camcorder video using Quicktime.

    Ok. so since I can't import it to imovie I tried to record a new video using quicktime. It would have worked except that quicktime would only recognize the sound input. Here is a video of the issue.
    http://www.youtube.com/watch?v=Qc1Wxjx6OmQ
    The camera I'm using is a Samsung SC-D453. Is there any way to make Quicktime recognize it?
    My other question is. Since this camcorder has a composite-s video out, Can I get a s video to usb adapter that will let me record it to Quicktime? Once it is in .mov IMovie will import it quite nicely.
    thanks

    Ciao
    you could launch the recording application, but it will not
    within your FL app. Then you need to know the file name and
    location since FL cannot browse the file system of the phone.
    Also consider that this type of apps do not work for every
    phone since some phones do not allow to execute other applications.
    Here some tutorials that you can take a look at:

  • Slow motion video from computer (backup) back to device?

    I keep getting idiotic bugs on my iPhone 6, and have been through all the iOS versions. So I have to keep doing resets with iTunes (deletes everything).
    I have quite a few slow motion videos on my phone. I back them up before the reset by simply copying everything in the DCIM subfolder to my computer. Question is....how to get the videos back on the phone after a reset, and register as slow motion? It seems impossible. Syncing a folder back with iTunes does not do this. Copying files back onto the camera roll folder is impossible. All I can ever do is get videos back but play in full speed. Thus rendering all slow motion captured useless.
    Have Apple completely messed this up?

    You have to email it to yourself to preserve the slow-motion effect.
