Sub-frame clip positioning in CS5?

[Mark Elf]

“On the other hand, if you separate (unlink) the audio track from the video track, and change the NLE timeline units to audio units, then you’ll be able to adjust audio very precisely against the visuals.”

Alex : I’m going to do a save as on the file I’m working on and unlink the audio and video track and experiment with NLE audio units.

Thanks for that

Very Best

To resurrect this thread (because I did I search for subframe positioning as well) you CAN do it. In the timeline, use the drop down box on the right hand side to ‘show audio time units’. (I think these are in milliseconds) and you can slide the waveforms on the audio track to line up precisely with the source audio files.

Remember that as far as I can tell, merge clips (if you’re doing this) only works properly with stereo source files that it then splits into mono tracks. You can change the audio files to stereo in the project window only if they are not on the timeline.

I don’t see that option, can you clarify where it is?

It’s only work if you’d rather be doing something else…

The option is on the little drop down box on the upper right hand corner of the TIMELINE. I still haven’t decided if it’s more accurate to sync to the clapper (when it’s fully closed) or to the reference audio on the DSLR.

This is a two parter for an old thread. First the image – this is can be accomplished by offsetting the image frame to frame and cropping. Then the audio can be synched as described above. You’ll lose some definition in the image, but you could shoot at 1080 and edit to 720 or even sd for the final cut.

I run into this when shooting SDI to ssd and AVCHD to sd with the same camera then going to split screen. lining up the shots using an overlay opacity of 50% works fairly well.

that’s ace. thanks!

Can this be done in after effects?

I would be super happy if I could fix this problem.

cheers 🙂

I too would love to be able to do this in After Effects, but can not find any options nor mention of one. Is this really a Premiere-only-feature?! Seems like proper audio synch would be integral to any such product..

I put this out to Twitter for After Effects and got this tip off Angie Taylor:

Open comp settings and double your frame rate, this will allow you animate between frames. When done animating change back 🙂

I haven’t tested it, but it make sense

Nice tip, thanks for sharing I will try this at work this week. Probably do something more like 8x frame rate to really get the audio synch. Will post here once I’ve tried it to confirm.

We do a lot of music video stuff and precise audio synch is important, and I don’t want to have to keep switching back to Premiere then to AE over and over so again thanks for the tip! Here’s hoping!
