Hi all.
I live in PAL land and use Reclock to play back my 25fps movie DVDs at 24fps. I'm currently in the process of converting them to AVC using x264.
However I believe that video encoders (x264 included) detect motion as part of the way they work. Presumably this motion would depend on the framerate of the source video. If this assumption is correct should I stick an AssumeFPS("ntsc_film") in my AVS script? I can then mux to mkv with 25fps timecodes to keep the audio / subs / chapters in synch, and it will all get slowed down together at playback.
I should point out that I've tested both ways and can't see the difference so I guess I'm asking out of curiosity rather than anything else. However if there's a minor benefit I might as well do it (or not if there's a minor drawback). There might be occasions where this is a good idea that weren't in my test.
Thanks.
