I am working with Panasonic AVCHD (MTS extension) files from an AC-130 camera. I am preparing a large project where I will need to prepare several hundred clips with DVE and compositing before assembly into the final video. It's more than I think PP nesting was really designed to handle, so I am thinking about processing each clip and exporting the results to a workfile for that clip. I'll do my assembly from the workfiles and proceed from there.
I am concerned about losing quality with the additional layer of rendering (raw footage --> workfile --> assembly edit). So here's my question: What would be the highest quality rendering format for my workfiles? Ideally, I'd like to find something absolutely lossless. Any suggestions greatly appreciated.
Lagarith Lossless Video Codec (pc only)
Ut Video Codec Suite (pc or mac)
'Virtually' lossless codec:
Avid Codecs 2.3.7 - DNxHD (pc or mac)
I think I can answer my own question. After reviewing my project, I have decided that I can divide it into eight parts, each with its own project. Each part divides into about two dozen slugs, which will be assembled into the final part. So, I will edit each slug in a separate sequence within the project, then create a sequence to serve as the master for the project. I will use the master sequence to do the assembly and finishing for that part of the project.
That approach seems to be well within Premiere Pro's limits, and it avoids having to perform an extra rendering of the footage. Thanks to 'Jor Bloe Premiere' for the codec info--that's very useful info to have.
