Vegas and Aftereffects - please help.

I have a project due tomorrow that simply drops a video segment that I shot and edited in Vegas into an AE template that the client provided. This is my first time using AE - I postponed the painful outlay of money until I had a client that required the use of AE - Now I have one. (yay?)

Here's the problem. (One of two). My video was shot in HDV and rendered from Vegas as DV-NTSC Widescreen (.avi) and is 3:17;00 in length No matter what I do in the AE render settings, the rendered output of AE is always 2:38;00. It looks good in preview, and the audio syncs (apparently a rarity in AE*) and in the preview, is 3:17;00 long.

* I've learned from researching this on the forums that AE just sucks when previewing or rendering audio, and if you get audio to sync in preview, then you are just lucky. However, in my rendered output the audio is WAY out of sync by a few seconds. Assuming that the audio render was part of my problems, I thought, no problem, I'll just render the video then match up the audio back in Vegas. I mute the audio and the rendered output is *still* 2:38;00.

I've tried Settings: 'Best Settings' and 'DV Settings', Output module: 'Uncompressed AVI' and 'AVI DV NTSC 48Khz'. Always the same result.

It appears that the whole composition has shrunk by 39-seconds. The start is OK and the fade-out at the end is OK, but if AE is going to shrink my render by :39 (any shrinkage would be a problem) I can't re-sync the audio back in Vegas.

Can someone please help me figure this out?

Thanks,
Steve Mann

I would check three things in AE:
1) Once you import the AVI file, right click on it and check the interpret footage settings to make sure they match your clip.
2) Make sure the Composition settings also match your footage.
3) Again, when you render from AE, make sure the render settings match the footage too.

In Vegas, make sure you are not accidentally rendering a 24p DV-AVI from your HDV footage. Alternatively, render from Vegas to a MOV file.

I seldom go from Vegas to AE - usually the other way round, but have not had issues either way.

In the AE comp settings make sure its not set at 2:38,, or you have set it in the timeline.......hmm read again and you seem to have the entire video only running faster?

Does it look faster playing back? If you want to send it to me I will try rendering.
Dumb solution, but would slo mo in Vegas solve the problem?

your problem is frame-rate (he says confidently).

probably you're working in 24 (or 23.976) fps and AE is selecting 29.97 fps (that's the default in AE if it can't tell by looking at the media).

here's the math ratio: 29.97/24 = 1.24875

your time difference
3m17s = 197s
2m38s = 158s

which translates to: 197/158=1.2468 (almost identical)

check frame-rate at each step of your process: files, composition, output.
