PROXY’s for high res animation files?
I am trying to edit a music video that involves the use of high res matted video of an animated character interacting with live people who are also matted (filmed on greenscreen).
Its a very processor intensive project. To make matters worse, I’ve rendered the animated character at a high resolution (apx 3K) so that I could do closeups and not lose resolution.
My question is, is there any format or codec that I could re-compress my animation files to in order to make them easier for premiere to handle, and yet still retain the same size as the original (not simply a scaled down version), so that when I’m done editing with the proxys and I go to “replace clip with” the size of the new high res video remains the same as the edited proxys?
The project is a massive headache in general and any suggestions for how to edit a music video of many mattted HD characters and include interesting crop/pan/zooming without losing resolution….would be very appreciated.
AE would seem to be the best answer, except that its a music video, so being able to playback and test timing is essential.
THANKS!!!

Any clip with an embedded alpha is going to be heavy on the hard drives. What does your storage situation look like? And how many layers of video are going on?

You didn’t say in what format are your source clips so not really sure, but there is great tool for such purpose I discover recently (and tested). This jpeg2000 codec is free, works as plugin for Premiere, After Effects and Photoshop (Win or Mac version), has lot of customisable preferences like bith depth, “yuv”/rgb, loosles with/without alpha or compressed (size or level) and many other features (eg: compliant with Digital Cinema Initiatives format). What is important in your case, it provides great quality in much less size than uncompressed or prores, isn’t cpu “hungry”, has something called autoproxy mode (when you choose Preview as 1/2 or 1/4 it decodes only half or quarter data – and check it out how looks 1/4 mode in comparison to most of other codecs).
In manual is also something interesting about (this one I didn’t tested yet):
“JPEG 2000 images can be saved in a set of tiles. This can allow an image decoder to view select pieces of the image instead of having to decompress the entire thing. Can be especially helpful with very large images. Defaults to tile size of 1024 pixels”.
As output is set of pictures all you need is import to Premiere and work on nested (can be replaced with clip as any regular clip).https://www.fnordware.com/j2k/
