Bryce,
That is the way audio works in AE – ONLY in previews and renders. It is not an editing program, so it doesn’t work like one (audio and real-time playback when you press play or the spacebar).
Again, audio is only supposed to work in previews, renders, or when you CMD(CTRL)-drag the CTI in the timeline.

There wasn’t any compressed audio, however, several files were DV Streams (.dv) – maybe that had something to do with it? The edit and audio was done in Final Cut and I brought it over with Automatic Duck. In the end I just ended up exporting the final audio from FCP as an aiff and all was well – but I’d still like to get to the bottom of it in case it comes up again. Thanks for the help.

I think so – I explained everything I tried in the OP – ram preview, cmd-drag, audio preview (num pad period) etc… as I said, the only thing that worked was CMD-dragging and a full render – RAM Preview and audio-only preview were not working.

Aahron, thanks for the response.
Yeah I tried that stuff…
The good news is that this seems to be isolated to one particular project, which probably not co-incidentally was one of the first I did with Automatic Duck — most likely I did something wrong or some of my audio tracks were screwy. But when I opened another project, and then started a new one, the audio issues were gone.
Still a strange deal though.

This really sounds like interlacing.
Are you previewing on an NTSC monitor or your computer monitor? If your computer monitor, and you used the DV NTSC preset, that means you are looking at interlaced footage on a progressive screen – so you will see “black lines” in things that move – these are “scanlines” and will not be visible on an interlaced monitor. They are even MORE visible on computer screens with hi-contrast (white on black).
If you will be outputting to an interlaced format (NTSC DV or DVD) then try to preview on an NTSC monitor and see if there’s still an issue. If you are NOT outputting to an interlaced format, I’d suggest working in a progressive comp (Ie NOT using DV preset unless you NEED it).
Any chance you could post a movie, so we can see exactly what it is you are seeing?

Excellent, many thanks for that very informative reply!

I always thought this was due to pixel aspect – so a 720×480 frame with DV pixels is 640×480 in square pixels (like in QT player) – for some formats it will even say “640×480 (720×480)” – not sure if my theory is right, but I know this is normal behavior for QT.

Thanks for the reply, Steve. I haven’t tried that only because I’m going to Final Cut and TGAs are less than ideal. I was able to work around it by rendering about 10-15 seconds at a time with the RAM preview method, but I’d still love to know what the issue is here – seems pretty strange since it is only an SD comp with pretty simple stuff in it.

Time to dig this post up…
Over a year later, new version of AE, fresh install of OS and all apps, and I STILL have this problem. In fact, it now happens randomly while working – no rendering or opening files necessary. I’ll be working along and get that error message “Error making file reference – file not found.” It happens every few minutes or so.
Could this have something to do with the way my drives are named? It is the only thing I can think of – why else would this persist after a fresh install of the OS and a new version of AE (CS3)?
please help this is driving me nuts!

Thanks for the info, guys. I was afraid that might be the answer – if I have to do it manually I may as well just not do it at all. We’re talking simple edits here, cuts only, just getting the hi-lights, so once I’ve skimmed through it once and found out it has “a hand”, I already know I want it in the timeline. Oh well it was worth a shot – thanks again.
