SD anime, 23.976 vs 29.970 fps ??

<< < (2/2)

cold_hell:
For normal 29.970->23.976 nothing special really, while TFM has alot settings and you should read TFM - READ ME.txt (894 lines, not so big)

for most sources something like this will probably work fine
deint = (whatever deinterlacer you want to use).SelectEven()
TFM(slow=2, pp=2, mode=5 ,chroma=true, scthresh=6, cthresh=6, micmatching=3, clip2=deint).TDecimate(mode=1)
however all depends on the source

Yes RTFM - I heard that someplace else too :P

OnDeed:
And if this wasn't clear, 23,976 fps (24000/1001) definitely isn't a thing of "SD" anime. Virtually everything is made at this framerate - which we often call just 24fps for simplicity, although it is not precise.

As for 29,970 fps, colloquially 30fps shows (the exact framerate is 30000/1001), there are mere few examples, and all that I know about are actually SD too:

Aria the animation (maybe the sequels too?), Kuttsukiboshi, Himawari! and Himawari!! (but at least in the case of the second season, the content was mixed - something was animated at 24fps and telecined, something was 30 fps).

Most of the stuff you will see encoded at 30 fps is actually just something that the encoders messed up and in reality it is 24fps.

Krudda:
You'll find that, if properly done, a 29.970fps encoded file won't end up larger than the 23.976fps encoded file (a tiny bit, but bugger all)
The issue is as everyone else here stated, the frames are choppy due to the 'extras' included.

I doubt I need to explain more, as everyone seems to have covered it well already, though you will benefit from reading the following link.

It's a little bit confusing for beginners (and some parts are still confusing for me :s, but overall, it will definitely help you understand the way framerate works and why)

This is not necessarily true. Consider this: if your source is hard telecine, then there will be unique fields in the repeated frames. Any noise in them will cause the "dupes" to be significantly different and it won't nearly compress in low amount of bytes.

BTW, x264 now adjusts its compression based on input framerate, so unless you override, it will treat a 29,970fps input more roughly than a 23,976fps source.
