Help please – audio export nightmare
Hello,
I am having a bit of trouble and am hoping you might be able to help. So far I have been at this for 5 hours straight and got nowhere.
The problem is that when I render a Quicktime file out of AFX, the sound slips against the video when I play back the exported movie – the sound seems to play a good bit faster than the video.
The footage is animation and composited video, and the track is an MP3. The end result is a music video, edited to the beats of the track, so it is important that the sound and video match up.
I have tried a number of different things, I have changed the sample rate to 41,000 kHz to match the MP3, I have exported the MP3 as a wav, also I have tried numerous settings in the h.264 export box, also mpeg4 compression.
What is strange is that both the source project and the rendered movie play back correctly in AFX in a RAM preview, and both play back correctly in Premiere also.
I am going for 720p 25 HD video settings.
Can anyone please help?
Ideally I would like to get this to work in Quicktime, but are there different delivery formats (interner – Vimeo) that would work better?
Thanks very much if anyone can help me.
Simon

One thing I’ve learned in AE is that your input audio should always be WAV. The mp3 support is kind of buggy. You mentioned you tried exporting your audio in WAV format, but I’m not sure if you mean on the input or on your render.
A possible workaround is to export video only to an uncompressed file, then add your audio back using Premiere or your editing program of choice, where you can do your quicktime export.
