View Full Version : Is this video REALLY hybrid?

Megui's avisynth script maker identifys it as Hybrid video with TFF, so I decided to use the 2 pass TFM process outlined here:
http://avisynth.org/mediawiki/VFR

But when I look at the resultant timecodes, the bottom reads:


vfr stats: 97.66% film 02.34% video
# vfr stats: 42280 - film 1015 - video 43295 - total
# vfr stats: longest vid section - 30 frames
# vfr stats: # of detected vid sections - 84



Which seems to be almost all film!

What would be the correct way to IVTC this?

a quick test could be done by running MeGui deinterlacer analysis

it's quite accurate (a great work by Berrinam)

Yeah, I already tried that and it said it was hybrid, but TFM reports it as almost all film...

Is it better to go with what megui recommends (which is something like tfm().tdecimate(mode=1,hybrid=1), or use the VFR timecode method?

Impossible to say without seeing it. If the video sections are in the middle of the show, it could be noticeably jumpy, but if it's at the end or very beginning it probably won't be very important.

Are there any significant downsides to using the MKV timecode method outlined in the avisynth wiki? Or rather, which one would get me smoother output?
