Conditions: My source is a cheap CCD, not too bad, pretty good detail, excellent chroma, some mild noise when in the dark but otherwise it's clean. The camera is amateurishly handled: quiet scenes interrupted by bursts of brutal motion. It stores the image in NTSC 480i DV format. I capture it with dvgrab over IEEE1394.
Goals: I want to put my movies on DVDs with the highest quality that's achievable with the mpeg2enc encoder. Also i want to obtain the highest portability and compatibility especially w.r.t. standalone players. When i can choose between two settings that make no difference quality-wise, i want the one which provides faster encoding. I don't care at all about the compression factor or the resulting file size (i never make DVDs bigger than 60 minutes). Now the questions: How often is actually needed -s? What do i loose if i don't use it? Any side-effects of -c? Is it a good choice to use -g 6 -G 18? Any possible side-effects of doing that? In general, when would you recommend to tweak -g -G? Did anyone actually encounter a set-top DVD player that gets upset by -R 0? Any chances for that to happen in the real world? What are the default values of -4 and -2? (the equivalent of not using them at all) -E -20 corresponds to what kind of quality? VHS-like? Broadcast-like? What's the _visual_ difference (the result) between positive and negative values? When would you recommend either side? What -E value would you recommend to start experimenting with in my case? Could you please comment on this combination of parameters? Anything that doesn't make sense? Any contradictory parameters? -b 9800 -E -15 -q 6 -R 0 -s -c -I 1 -g 6 -G 18 -4 2 -2 1 -K tmpgenc -N 1 Whenever that makes sense (such as what are default values, etc.), please add the answers to these questions (if any) to the mpeg2enc man page.
