Quicktime pro recording video playback too fast

I'm using Quicktime Pro to make a video recording with audio using the "Best" settings in the preferences (i.e. h264 encoding). When playing these videos back, the audio sounds good, but the video framerate seems almost x2 the speed as it should be. Below is the output of ffmpeg on one such movie. The output points to the fact that there's a problem with framerates, but I'm not really sure how to interpret it towards getting a solution. Any ideas on how to fix this so that we get audio video sync'd up and at the right speed?

Hello,
I think it has something to do with audio settings in your camera.
There's a menu where you can choose 12bits audio or 16bits audio.
Change the setting and try again.

Quicktime Pro recording video - dimensions presets

It appears that the QT Pro presets for recording video (all two options) depend in part on what maching you're using it on -
On my G5, the videos recorded are 320 X 240, which is fine for my purposes... but on my Powerbook (with which I'll be doing the actual recording), the videos are 240 X 180, which is too small for my purposes.
Has anyone discovered a way to change these settings? Or to "fool" QT Pro into thinking it's on a different machine so that it will allow for larger dimensions?
Failing that - any suggestions for other software to record 3-4 hour meetings using an iSight and a Powerbook? (I've tried BTV, but can't get the file size to quality ratio anywhere near as good as QT Pro, and BTV seems to create huge swap files or something that make several hours of recording impossible).

Thanks, QuickTimeKirk... I've got SnapzPro and gave it a shot, having it record the QT Pro record window (without having QT record, of course)... but one of the things I like about using QT Pro itself is that it appears to do the capture and the compression all at once -- i.e. no post-processing needed. This is ideal because the plan is to copy the movie to a USB thumb drive for the client at the end of the session; waiting for a 3 hour video to save and convert/compress won't work (hence something like iVezeen, while good, won't do).
Anyway, I have managed to change the dimensions via the .plist file that applies to my Powerbook. The next thing I want to try to change (if possible) is the framerate - it doesn't really need to be as high as it is for our purposes, and would cut down size (and processing cpu usage?) if I could reduce it to 15 or 20fps. I can't find that setting anywhere in the .plist files though.
Any ideas?
Thanks,
Scott

Videos play too fast on ipad - sounds like super high speed mini mouse

We just bought the ipad and when we play videos on vimeo or youtube they play at an ultra high speed like the fps is messed up - it sounds like a record being played too fast
Is this our ipad or a setting - we are worried because we do not see the problem listed anywhere else.
Thanks!

Have your rebooted/restarted your iPad? you do that by pressing the Home and power/sleep button at the same time until the slider to power off the iPad appears. Slide the slider and when screen activity stops depress the two buttons again until the Apple logo appears. When the iPad completes rebooting try again to see if that solved your problem.

Can quicktime pro capture video stream?

Can QT pro record video streams off the internet? I thought it was only able to capture embedded video files. Video streams aren't donwloaded into cache, so they have to be saved as they're received. Could someone clarify? Thank you.

Pro can't save true streaming media.

Sample rate/quicktime pro audio/video

Hi all:
Have a few questions related to Quicktime pro on mac related to sample rate of audio and video...any help understanding much appreciated...
I am a music composer using logic pro and recently started working with filmakers who send me quicktime files of the video to score to...
regarding sample rate of audio as played back in quicktime...I'm a bit confused....
When playing back either an MP3,wave,Aiff at 44.1k or 48k
seems that quicktime plays at the right speed and pitch of audio...Does Quicktime use it's own audio processor to convert sample rates in real time at playback?
When I play a video track with audio recorded at 44.1k or even an MP3...and playback on my soundcard set at 48k...it does play at correct pitch...even though theory of audio tells me that the sample rate is very inportant especially when playing back...sample rate needs to be the same on both the soundcard audio clock and the software...
Is this part of the magic of quicktime or am I missing something.
Even a bit more confused when I got a dialog file from a filmaker attached to his quicktime file that he thougnt was in 44.1k...was actually 48k...so when taken out of quicktime and put in another enviornment for editing that became really important and avident that the samplerate audio rules outside of quicktime applied...
Am I correct then in my understanding that when working only in the quicktime enviornment that the rules of audio sample rate do not apply?
Thanks for thoughts...
regards

QuickTime 7 is a major re-write and it now has many more options for audio. Multiple channel support (up to 24) and sample rates of double DV Stream settings.
Magic is how it works.

Quicktime 7.6 video playback issues

I upgraded to quicktime 7.6 yesterday and is has caused video playback issues when in higher performance with my Macbook pro. I am trying to play 1080p footage in the h.264 compression codec and it is now stuttering. It played fine in my previous quicktime player before the upgrade and it seems to play fine in the better battery setting. The problem occurs with the 9600 nvidia chip but the 9400 works okay. This is troublesome because the 9600 should out preform the 9400.

Update: The problem only happens with MacOS 10.5.6. Running the pre-installed MacOS 10.5.5 the 9400M and 9600M displays movies smoothly using QuickTime 7.6. Disabling hardware-accelerated playback by deleting the "AppleVAH264HW.component" in "/System/Library/Quicktime" also "solves" the problem.

Video playing too fast

Don't know if anyone else has this problem but for some reason I was and I seemed to find a weird work around. I had an AVI, divx codec, ac3 audio that the video was playing WAY too fast but the audio was fine. Well, seems that Quicktime is getting the frame rate screwed up and when I opened it, if I immediately to to "Movie Properties" to look at the frame rate it will play fine. If I try to play it and then look at the properties it won't play right. Almost as if it has to find out what the frame rate is at the beginning. Very weird but a bit of a work around for now. Hopefully this will be fixed. It was using Perian to play it.

I have experienced a similar quirk, with several different videos, including .m4v clips that I have downloaded or created myself. The problem doesn't occur when previewing the movies in the Finder, nor when playing them in iTunes. However, if I open the files with QuickTime, the video plays faster than normal, but the soundtrack plays at the original rate! I tried your solution of opening the Movie's Properties first, and it does seem to work. Of course, this is only a workaround for now. Obviously, something needs to be tweeked in Leopard or Quicktime —most likely both— to eliminate the quirk entirely. I am very surprised by this problem because one would think that Apple's own software products would be more compatible than third-party programs! Yow...!

Quicktime pro for videos

Do i need quicktime pro to convert video to watch on my ipod?

Try using an application such as MPEG Streamclip to convert the video.

Audio playback too fast

I have an ipad2 and I'm having problems with the audio. The playback of audio files saved on the ipad is too fast. The same files playback perfectly on my pc. This is not the case for audio streams playing directly over internet radio - no problems there.
Any suggestions of what can be done?

Try quitting the iPod app. First go to the home screen. You cannot quit an app if you are in the app itself that you want to quit.
Quit the app by double tapping the home button to bring up the multitasking/recents tray at the bottom, hold down on any of the app icons in the tray until all the icons wiggle, then tap the minus sign in the corner to quit the offending app or apps. Restart the iPad and try again.
Restart the iPad by holding down on the sleep button at the top of the iPad until the red slider appears, then slide to the right to power off the iPad. Turn the iPad on again by pressing the sleep button until the Apple logo appears. Once the iPad has fully rebooted, find your app, and tap the icon to relaunch.

QT Pro recorded video not compatible with FCP?

Is a video recorded in QT Pro compatible with FCP?
I was getting errors earlier today importing QT video clips recorded in QT Pro.
FCP said "unknown file type" and wouldn't import it.
I tried different decks, different footage, all to no avail.
Drag and drop, file>Import, neither worked.
I never tried this before and was surprised.
It's not that it needed rendering, it just wouldn't import.
QT was set to use the native format of the recording device.
FCP was set to DV NTSC easy set up.
OS 10.4.7, QT 7.1.2, FCP 5.0.4.
Thanks,

The files open fine in QT player.
640 X 480 was the QT captured frame size, 29.97 fps, and it was captured as "device native" in QT preferences. The source tapes where mini DV/NTSC so its frame size should be 720 X 480.
If this frame size is the problem, why is QT pro recording a 640 X 480 image when the original is 720 X 480? Also, can't FCP handle a 640 X 480 QT video size anyway?
I tried different tapes with different decks and kept coming up with the "file not recognized" error when trying to import into FCP.
Thanks for your help,

Microsoft 2000 OS, all videos playing too fast, what to do?

Have MS 2000 Professional OS
All online streaming videos (like youtube) playing too fast, extremely annoying rushing "chipmunk" effect.

Word is getting around on the internet that Apple has basically stopped monitoring and moderating these forums. Expect to see this sort of thing increasing. If Apple isn't going to keep a lid on trolling like this then they had better just shut the forums down. It won't take long for these forums to be totally overrun by Mac bashers, trolls, and Windows fanboys. There's something about the Mac that scares them and makes them feel insecure.

QuickTime Pro recording Desktop, finder

I have a simple question, before I buy QuickTime Pro.
I need to be able to record everything that happens on my desktop, I need to do a few tutorials of different programs and want to record everything that takes place on my monitor.
Is this possible with QuickTime Pro. ??

There's a nice rundown of many of the current options posted here.

Quicktime Pro Record Webinar Audio

I'd like to record a webinar (audio) that I'm listening to Tomorrow night.. I've been searching the net for a program that can do this ? Can I do it with Quicktime Pro ?
Any helps or explanations would be most appreciated !!

QuickTime recordings can only be made from input devices and not from what plays through your speakers.
You need an audio capture software app like WireTap.

How do I make Quicktime Pro my preferred playback software?

I use VLC Player and Quicktime Pro. Recently, however, I've needed to use Quicktime for streaming purposes - but VLC comes on almost immediately.
How can I make Quicktime my default or preferred player?

*Changing the application used to open all files of a certain kind*
1) In a Finder window highlight a file of the kind you want to change the application to open that kind of file.
2) While that file is highlighted, select File > Get Info or press command (apple or propeller icon) + i to get a file information window.
3) In the lower part of the info window there is an "open with" menu with a list of applications.
4) If your application is already in the box then it is the default application for opening that kind of file and you don't need to do anything more. Close the get info window.
5) If the application showing in the menu is not the one with which you wish to open the file then select a new application. If your application does not appear there then select the "other..." and track down the application (usually in the Applications folder at the main level of the computer).
6) If you wish to change all files of this type to open with this application in future, make sure the "change all" button is selected.

Premiere Pro CC video playback gone after render

Hi all,
I'm having a playback issue. Premiere CC is running smoothly at first, but the moment I render effects I lose video playback. I can still hear audio, but no video. I only regain video after Force Quitting. Thoughts?

Have you set the previews to be sent to a slow or full disc?
