Remove Duplicate Frames

[Mr. Fanservice]

How do I remove duplicate frames from videos?

You will always have to reencode, what exactly needs to be done depends on what you want:
a. just remove them
b. remove them and turn the clip from cfr to vfr
c. replace them with an interpolation of the neigbouring frames
...
and what the characteristics of your source are. There are multiple ways to do this through Avisynth or Vapoursynth.
Adobe Premiere and similar NLEs also have options to do this through a gui.
If you want to use ffmpeg, mpdecimate is probably the video filter you want to look at.

Ps.: you should be able to find an answer using the forum search, this has been answered before.

Once I did dumb trick of decimating freezing screencapture by:
-convert video frames to png files with ffmpeg
-Find duplicate images (by md5sum or with Total Commander) and delete pngs.
-re-encode unique pngs to new video and add original audio with ffmpeg.

I got 14.5 fps vid (calculated total frames by time) still it was not freezing.

Hi, Simple Video Editor have an function to select to delete duplicate frames, basicly just drag and drop the video or browse for it and then select Delete Dulicate Frames.. The command line can be customized by pressing ctrl and then on the save/proceed button! You might want to increase the process priority in the Windows Task Manager to get better loading times and such things! Ive tested the version 1.4.2.0 but there is newer versions avalible allso!
