[NEW] FFmpegForge

[DVWannaB]

Just happened to bump into this thread today. So I decided to download (Win64) and give it a go. Impressed so far. Compressed a large h265 file 1920x1280 5.1 AC3 13Mbps to smaller 1280x720 2.0 AAC 2500Mbps. Fast encode and quality is great. Thank you to developers and you got my support homie!!

Hope someone can help. Still is early experimentation with FFmpegForge and wanted to test converting a 29.97 movie to 23.976 that I recorded from a cable movie channel. I have done this successfully many times using Avisynth for scripting using Tdecimate and encode with MeGUI. Tried mpDecimate auto settings in FFmpegForge and it randomly has some scenes with a slight motion stutter. Anyone have any idea how to properly use settings in mpdecimate to accurately and smoothly decimate? Thanks.

The basic filter in ffmpeg for IVTC (Inverse Telecine) is

-vf fieldmatch=order=tff,decimate

Thanks Sharc. FFmpegForge does include a detelecide filter, but provided much worse results than mpdecimate.

@Aaronstanleyfx - I would like to request if it is possible that the developer port the Avisynth Tdecimate filter into the filter listing within FFmpegForge. Thanks.

Decimation (e.g. TDecimate in Avisynth) alone is not sufficient for proper IVTC.
IVTC (conversion of NTSC 29.97 fps video to 23.976 fps progressive film) involves 2 steps: Field matching and decimation. Both are available with ffmpeg. No need to port anything. See the ffmpeg filter example in my post above. Or perhaps a bit more elaborate try

-vf fieldmatch=order=tff:combmatch=full,yadif=deint=interlaced,decimate
