I have a piece of video that’s exactly 30 fps but every fifth frame is a (visually exact) duplicate of its predecessor, suggesting that its true framerate was 24 (or perhaps 23.976) fps. It is not interlaced.
Viewing it in a typical media player looks too jerky for my liking, so I’d like to delete the duplicated frames and end up with my video running at the ‘true’ speed of 24 fps.
I’ve used Avidemux for many years and I think it’s wonderful for something that’s completely free open-source, but getting it to delete duplicate frames has caused me to pull my hair out many times over!
I’ve tried using Avidemux’s deinterlacing filters (Decomb Telecide & Decomb Decimate) even though the source file isn’t interlaced. However, my struggles have come from the tutorials out there being a bit light on detail when it comes to selecting the options.
Strategy – No strategy, 3-2 pulldown, PAL/SECAM, NTSC converted from PAL
Field order – Top, Bottom (this seems completely superfluous as my source isn’t interlaced, but I have to select one of these)
Postprocessing – None, None but compute, Postproc on best match, Postproc and show zones, Process image (not fields), Process image (not fields) debug
Try backwards – Never, If still combed, Always
– values for various threshold settings, etc.
Cycle – integer value – I presume I want 5 in this?
Mode – Discard closer, Replace (interpolate), Discard longer dupe, Pulldown dupe removal
– values for two threshold settings
Based on the above information, could someone guide me on which options I need to select to get what I’m trying to get?
