Workflow for HD multi-camera editing CS4?
Hi there. I have some AVCHD files shot with my Panasonic HMC40. The files open natively in CS4 and play fine but not as a multi-camera edit. Multi-cam is way too slow to edit smoothly. I read somewhere (on a cow forum I believe) about saving the hd as avi to create a multi-camera edit, editing that timeline, then replacing the avis with the HD clips.
This sounds like it’s exactly what I need but I’m curious about the timeline dimensions to be using. Should I be using all HD sized (1080) timelines for both the original timeline with layered avis (stretched to fit) AND the final multi-camera edit timeline? Once I’m done editing that I would then replace the AVIs with the HD footage (which would update the final timeline?)
I’m concerned about render time as well (the render time to allow the multi-camera edit to flow). I know the rendering takes a little while with all AVIs so I hate to get started on this 2 hour timeline in the wrong format!
Thank you for any suggestions!

This is just my own two cents. I never play the video during multicam editing, I just scrub it using the shuffler. This usually saves me time later in the trimming phase.

AVCHD takes a LOT of power to decode for playback, as you’ve found. You may have a better experience using an intermediate codec. This might be the “avi” that was suggested to you, and it also sounds like there may be some confusion regarding this, about “replacing with HD later”. The .avi IS an HD video clip, you convert the AVCHD file to an easier to edit (less compressed) .avi file, and then work with the replacement files all the way through the process.
You can get a free trial of the Cineform NeoScene codec to try for a period, you might want to give it a test. It will convert your raw footage to Cineform .avi files, which will be larger than the originals, but the new files will playback much easier.

I was going to suggest Neo Scene too.
But I wasn’t sure how well it would work under multi stream playback conditions.Alternatively I suppose you could output DV Widescreen versions of your clips
edit with those and replace with HD source when done.But I don’t know the exact steps of the replace
