I just imported some converted AVI's into my FCP timeline, hit render, the waveforms show audio, but the audio just won't play along with the picture. No sound coming from those clips, even though the clips do sound when i play them on the quicktime player.
I also at the same time imported an aif music clip, and it plays fine in FCP. Both clips have the volume line up. Another AVI audio clip from another source renders and plays fine in the same FCP timeline. I'm scratching my head on this one.
These newly imported AVI clips, 3 of them, the video plays just fine, the waveforms are there in the audio clip big and bold, but the audio just doesn't play. I had converted them in the "Mp4toAVI convertor.
"Life is good, as long as it doesn't take up too much of my time."
Did you set the conversion to make the audio uncompressed 16 or 24 bit, 48khz? FCP doesn't like compressed audio codecs so unless you converted the audio from mp4 or aac or whatever it was compressed at to uncompressed, you will have problems.
