Avidemux Forum

Hello,

Here, I want to convert a 29.970 interlaced video to 23.976 fps (which will therefore be deinterlaced) but when I try to modify the framerate in Avidemux, it also modifies the duration of the video.

Usually, I go through Avisynth for this kind of manipulation and by doing a Decimate, I can do this without modifying the video timer.

Is such a thing possible in Avidemux and if so, how?

I take this opportunity to ask you another question about deinterlacing: in Avisynth, for the videos I want to process, I apply: tdeint mode 2 but this does not seem to exist in Avidemux.

What would be closest to it? Better yet, is it possible to make Tdeint work in Avidemux and if so, how?

Thanks.

The video filter performing this operation without modifying duration is called "Resample".

I cannot tell how close the results are to TDeint, but the best cross-platform deinterlacer in Avidemux is Yadif in picture-per-field mode. On Linux, hardware accelerated deinterlacers (VDPAU and VA-API) work pretty great on hardware with necessary capabilities IMHO.
