* Ripping TV Shows *
These are my notes from all the testing with bend on TV shows.
Some generic conclusions:
- Do a two-pass and force deinterlacing on a live-action show for best results if the show is not variable framerate. - Do a one-pass with hard_fps dropping on cartoons - If it's a variable framerate, do a one pass and force the input and output framerate.
Everything else documented revolves around those three basics.
* 2pass notes
The two passes on cartoons seems to blur the lines in every case. It could be because I'm not doing –hard_fps at all, but adding that usually throws the A/V out of sync.
Without deinterlacing on a 2pass, you will see some horizontal lines as artifacts on *some* shows, not all. It seems to be the minority, actually, as most do fine with just 2 passes.
For deinterlacing (on 2 pass), -I 1 and -I 3 seem to work fine. -I 3 has consistenly delivered great results, and limited testing proves that -I 1 works fine. The only problem with -I 3 is it doubles the encoding time, so a one-hour show will take up to 4 hours to encode on two passes.
* 1pass notes
If you are forcing the framerate, go ahead and use all the filters mentioned in framerate.txt.
If not, just use 32detect. Adding anything else throws the a/v out of sync.
You can use –hard_fps on both, though.
Generally speaking, 1pass usually will result in larger filesize. The difference between one and 2 pass for filesize can be dramatic (I've seen from 20 megs to 200), but not consistently rational. If a one-pass is working and looking really nice, go for it. You'll probably end up with larger files, but save time and get good quality.
Overall, I'd say use the one-pass method if you can afford to be very liberal with harddrive space. There are some cases where using it actually causes jitter, so the two-pass is better because it cleans that up.
