387 Mb QT file plays back three seconds of black

I have exported a project from Final Cut Pro 3 as a Quicktime. The size is 720x480, anamorphic box checked. The project is 4:30 in length, and took over 90 minutes to export.
When I try to play it, I have 3 seconds of a black frame with no audio. Get Info tells me that the file is 387 Mb. Where is all the data? What did I do wrong?

DVDSP can't create slug. You can either import a PICT file of a black image at the right dimensions and drop it right into your track in DVDSP, or you go back to FCP and create a few seconds of slug and encode it to MPEG2 and import it as usual.

HP G56 intermittent sound problem - e.g you tube/MP3 files play for 10 seconds then stop.

HP G56 intermittent sound problem - e.g you tube/MP3 files play for 10 seconds then stop. I have made sure that the latest sound driver is installed and this makes no difference. The laptop is new so there is no other software on it other than the pre-installed stuff operating on windows 7. In sound options all looks well and the device is said to be working properly. Even the sound test in device manager sometimes works and sometimes doesnt.

Can play fine on browser, but some .wmv's only play back 1 second??

Gentlemen,
Ive noticed that a couple of websites that have only .wmv available to download movies. I am running a Mac G4 with OS Tiger and Opera for the net. I can easily play wmv's with QTpro and or VLC.
The movies that I typically DL are usually 300 to 400 megs. They completely on DL on my browser (Opera, Safari, or Firefox) after about 10 minutes or so. However once I DL the .wmv files onto my harddrive , they show up at only about 3 or 4 kb!!?? So thats about a total of like .2 seconds of play back!!??
I believe this is not an Apple vs Windows issue, but something else. Any ideas?
Thanks guys!

.wmv are Windows Media Files, for which you need:
Flip4Mac WMV Player from
http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
If you don't have it already you should also get
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.

WAV files play back too fast

When I choose File->Open to open an AIFF, MP3 or other file in Audition CS6, it simply plays back at normal speed. However, when I open a WAV file, it plays back at double speed (voices become high-pitched). NOTE: The sample rate (44.1) and bit size settings match exactly. This is not a sample rate issue. The frame rate is NOT set to custom.
This happens only to WAV files. The platform Mac OS X 10.8.3. Any ideas?

For some reason the songs seem to play back faster than they should. Any ideas?
How much faster? Have you timed the playback speed with a stop watch and compared the actual duration with the duration (Time) in the browser?
If youtube plays back slower, it might be caused by the network.
I have only seen this on iTunes for Windows so far - you are not by any chance on Windows right now, are you?
Are you running the latest version of iTunes?
And do you have any non-standard Audio devices installed - look at System Preferences > Audio > Output ?
Did you install any Audio Drivers?
Also look at the Audio Devices in Audio MIDI setup (Applications > Utilities):
Check the Format for you output device if it is set to 441000 Hz (compare the setting to the sample rate you see on your songs in the iTunes Library).
If this setting is wrong, iTunes may try to playback at the wrong speed.

Elements 9.03 with Windows XP - Only Audio Portion of Video Files Playing Back

I'm using Elements 9.03 with Windows XP. When I download videos from my Sony HandyCam, the video portion of the file does not play back, only audio. Is there a setting I can adjust or do I need to use a more recent version of Windows?

The video format may not be supported e.g. if AVCHD
If you ever consider upgrading your computer and software, you will get maximum benefit from the combo. Photoshop Elements + Premiere Elements. As well as being the best value for money, it supports all the modern formats and allows the burning of HD DVD’s and many other options, not possible in PSE alone.

URGENT Strange problem with no audio files playing back in arrange

Anyone ever have something in Logic Pro X (newest .1 update, auto updated on me but seems fine otherwise) where playback of audio just stops? Like, meters still move for automation, audio files still remain in place, but nothing is even metering? Another alternative of this project (which i dont' want to use) works, and this just sorta stopped playing back. nothing i can think that triggered it. I can start up a new instrument and it plays back and records just fine. All of my existing audio just won't play at all.
I tried changing my interface and back in preferences, I've restarted both program and machine, but just this one alternative of this project (the current and most important of course) just won't play back audio. It even plays back in the wave editor window, just not in the sequence.

Why don't some audio files play back in enhanced iBook?

I recently bought an enhanced iBook in iTunes for my iPad and most of the audio files play. A few do not when I click on them. The player goes blank (disappears) and nothing happens. Does anyone have a solution?

In iTunes, select all the songs/files you want to stay where they are.
Right click - get info.
Tick *Remember position* and set it Yes.
You can do individual songs or a bunch at once.

Audio file plays back in mono

wierd one this...
a stereo mix (rendered as a stereo interleaved aiff) plays back fine in preview, itunes and when dropped onto the arrange window. however, when it is auditioned from the Sample Editor or from the Audio Window it plays back in mono. this is not my project so i dont know exactly what has gone on before, but when i import it into a new logic project and try the same thing, it is fine.
any ideas?

solved my own question thanks!

CS3: Exported .mov file plays back very slowly and choppy

I'm exporting a 1020x574 stage to Quicktime, H.264 High
quality, no sound. The resulting video, no matter what size I make
it, always plays choppy at parts. It plays fine in Flash and as a
.swf, but the .mov lags badly.
Any ideas what's going on?

Yes, that's the exact same problem I'm having. And I see the
same thing, where areas with more objects tweening and effects and
such have the lag. The thing is, when I play the .swf in the Flash
Player it runs without *any* lag, so it doesn't make sense to me
why lag is picked up when it records it for QT.
I have noticed that if I shrink my entire stage and export at
a smaller size, it runs without lag. That is not an option,
however, I need the larger size.
Well, that's disappointing. Next step is to try and find a
good screen video recorder and manually record the playback.

My LT file plays back faster after I render

When I render it and import it into FCE, the credits scroll faster, a good bit faster I'd say 20% or so. As a result, my credits come up 10-15 seconds too short. Why is it doing this? I've been at this for 3 hours and it does it every time.

Sounds like the frame rate settings in LT and the frame rate settings in FCE don't match.

Exported movie plays back fast

Hi all, new poster on the apple discusions forum but wondered if anybody out there could help me.
I created my first movie from iMovie last night, the footage is HD from A Sanyo Xacti 1000 camera (had problems getting the footage in the night before but thanks to these boards found a solution)
Anyway cut a quick movie exported to AppleTV, created my m4v file, played back on ATV and the video footage appears to be running fast, almost like it's dropping frames but smooth. Audio was fine too... Anyone got any bright ideas?
Thanks tim

Hi.
Best thing to do is to set Imovie'08's movie format to NTSC, even though the TV standard in the UK is PAL.
But since you work ith non intelaced footaged, this will just change the frame rate iMovie works with to 30fps (29.97 exactly) instead of 25.
Since all Xactis shoot at 29.97 or 59.94, this setting is much better for them.
And it totally eliminated any choppiness effect for me.
Beware though: changing the PAL/NTSC setting of iMovie from PAL to NTSC made very strange results in edited movies (offset edits) when iMovie came out. I do not know if this has been corrected in the latest 7.1.1 version.
But you can always go back to your previous PAL setting and this eliminates all side effects, so there is no real downside trying.
I also have an HD1000 now and have had no problem with 60fps footage- and I now know how to output from iMovie at 60fps
Not sure if this has to do with it, but I do not use iMovie's import feature:
I create a folder for the new event in the ~/Movies/iMovie Events/, copy the .mp4s from the HD1000 to it, and then launch iMovie. IMovie then creates thumbnails and everything.
Hope this helps.
I miss the good old times of miniDV, when everything just worked!

Audio doesn't play back through DAE audio tracks

I work on Digidesign HD hardware and Logic as a front end and a problem has crept in over the last week or so.
I will be working on a song and suddenly with no warning Logic freezes for about 30sec or so. After this all audio files playing back on DAE tracks will not playback or white noise plays back from those track. The DTDM tracks and instruments tracks work fine. This happens wether i have a couple of tracks on the go or loads. It's like the DAE audio playback side crashes but all other things still play back through the DAE so it half works.
PLEASE PLEASE help as i have to reboot Logic everytime and 10-20 mins later it happens all over again.
Thanx
G5 dual 2Gh Mac OS X (10.4.2)

Just some quick thoughts....I'm not a "techie", but have had my share of softwaretrouble!!
It could be that Logic is set to global 16bit - and you try to play back 24bit files. Had kind of same problem a year ago, but don't remember if it was Logic OR ProTools that gave this result (played for a while...then a burst of white noise). But the crash...no. This is probably caused by other components. It's usually a good thing to trash the Logic preference file and restart. Then check preferences>audio>drivers>DAE that the global bitrate is set as desired (according to your already recorded files). The DAE preferences don't contain that much information, but could be helpful to trash too. Just remember to set the playback buffersize to a reasonable amount for your setup.
Hope this will help.

Quicktime .MOV file plays audio only - no video

Okay, here goes...
I created a .MOV file from Avid via the H.264 codec. This file contains video and audio and was made on a Mac using Leopard. I played it back successfully on that machine.
I then copied it to a data DVD and put it on my XP PC with all OS software up to date. I have a freshly updated QT 7.6 install. The files will only play back audio on my PC - video appears black (if preferences are set to Direct X) or white (if preferences are set to safe mode). Video card is an NVIDIA GeForce 7900 GT/GTO; driver is up to date.
Anybody have any insight into what I need to do to my PC to get this video to play?

Thanks for the link. Unfortunately, it doesn't directly address the issue I am having (though it does show me the world of hurt out there when FCP and Avid bump up against each other in the same post process).
And the third-party page doesn't have any codecs for Avid.
Again, I am at a loss. I created the QT files from my Avid project on a Mac. The files played back properly on that Mac. They won't play back on my Windows machine, so I can only assume that there's something missing or different between the QT versions for Mac and Windows.
Since I can't figure out how to get these files to play properly on a PC and since my home machine is a PC, I guess I will not output footage from Avid to a .MOV file in the future. I will try to find a format that Windows Media Player likes, I guess.
Thanks for the help.

Video Plays back vertically instead of horizontally

I shot a video with my bloggie touch of a stage show, holding the camera horizontally. My problem is it plays back on the Bloggie and my computer vertically.
Is there a way to rotate this video? Otherwise I can't watch this, and the video is useless.
Any thoughts?

page 17 shows the views of how the picture was taken
http://www.docs.sony.com/release/MHSTSs ... ndbook.pdf
Yes you can shoot video in any orientation, However, for a widescreen movie It is recommended to shoot your video in landscape mode. If you shoot holding the camera vertically, The video will record and play back vertically showing the black aspect ratio bars you see on the above page 17. For widescreen, 1920-by-1080 video, you'll need to shoot in landscape mode, with the screen sideways and the Record button to the left or right.
In order to rotate your existing video you will need to use a video editing software to edit and save. Windows and Macintosh operating systems alike both have basic video editing programs that came standard, or is readily available for download with the software.
