  Audio shrinking on rendering

  Posted by Wbhend on December 12, 2006 at 10:15 pm

  I’ve rendered a series of comps with animated static images (no video footage) with mp3 files as audio for timing. I intended to place the original mp3s in Premeire under the video footage before converting to DVD however the length of the audio in the AVI files have now been shortened as compared to the raw mp3s. I’ve used both Microsoft DV compression as well as no compression and have received the same result. I’ve also encountered a noticable pop in the mp3 file in AE which is not there in the original. Any ideas?

  Thanks in advance for any responses.

  Hmmm… I think I had the same clicking issue with uncompressed wav files out of afx. I’m not 100% sure if it was uncompressed or any PCM/ACM wav codec.

  But to avoid trouble I’d recommend rendering/exporting the audio of all video files into one wav and resynchronize it later with any audio editing app.

  Your audio probably got resampled, something neither AE nort Premiere are particularly good at (more specifically they do not properly align the temporal compression in the MP3s). You should make it a point to convert them to PCM files, just like the others said.

  Thanks all for the responses. Major reworking involved. Lesson learned.
