Thanks for this suggestion. I will experiment with it and see whether this solves the problem.

Thanks for these suggestions.

I can’t see (or hear) anything wrong with the source audio.

I don’t think it’s a defragmentation issue – the first thing I tried was to defrag the disk the files are on, and this did not solve the problem. Not only that, but the glitches come in the same place every time I render the files – if it was a fragmentation issue, I’d have expected the glitches to move about, depending on where the files were being written onto the disk.

Additionally, there are no changes / key frames etc. in the AE file at the points where the glitches occur.

I’ve tried exporting just the audio as a .wav file, and looking at the file in Audition. It looks as if AE has lost one or more frame’s worth of audio at the point of the glitch – but I still don’t know why. More importantly, I don’t know how to fix it.

Thanks for this suggestion.

The source audio is from two .avi files (i.e. it is video and audio combined). The .avi files have been edited in Adobe Premiere before importing into After Effects, and there aren’t any problems in the audio of the files after exporting from Premiere.

With best wishes.
