Thanks for the ideas Uli. Let me respond:
The frame controls were ON and consistent with all 3 attempts. Without them set to their highest qualities, the video comes out much worse. Still, with those settings all ON, the first 2 shows came out via Compressor in 7-8 hours, the 3rd had trouble. I should mention this also happened when compressing trailers for these shows–2 of 3 compressed in much shorter times than the 3rd, and no, that 3rd was not part of the same full program that is taking a long time now.
I am starting with a stand-alone DVCProHD 720p 59.94 file, and ending in a MPeg2 59.94 file. No FPS changes. I do have to resize the aspect ratio when I spit out of FCP, to get rid of the HD anamorphic–so I’m exporting as 1280×720 rather than 960×720. I’ve done tests, and this step seems necessary to ensure the final DVD aspect ratio is consistently correct.
We do have MPeg Streamclip–I will try your suggestion for downscaling from HD to SD with that rather than Compressor, separating the 2 steps. Likely will save a lot of time. Are Photo JPeg and DV50 the best codecs these days? I am more concerned with saving time than saving drive space.
