Saving files
I’m using CS5 on a Mac and have a simple question. I want to save final chunks of a project and them bring them back into Premier to edit them all together. What would be the best (highest quality) files to output my video for import back into premiere (if that makes many sense)/

Use ProRes/DNxHD/AVC-I/Cineform for standard HD resolutions; uncompressed or PNG/JPEG2K for other sizes.
– Uncompressed formats such as RGB(A), YUV, or DPX produce the best quality but generate very large files.
– The preferred approach is lightly compressed, 10-bit, all intra-frame, 4:2:2 or 4:4:4 codecs such as ProRes, DNxHD, AVC-Intra, or Cineform. These formats withstand multiple generations of edits. However, they are only available in standard HD resolutions.
– PNG and JPEG2000 image sequences offer lossless quality and compressed file sizes. There is some risk of color conversion artifacts from 8-bpc RGB color.Another approach is to work with each sub-sequence individually within the same project, then nest them in a master timeline. (Premiere treats a sequence like a clip when it is inserted into another sequence.) This avoids the need to encode intermediate files. However, it requires all effects to be rendered during previews and final export.
