Feature Request - Frame interpolation

[TheInvoker]

Hello
Is it possible to add this feature to Avidemux?

i know there are already 2 filters that change FPS but none of them actually change the smoothness of the video

Change FPS isto slow/speed the video
Resample FPS should be the one to go for interpolation but even changing from 30 to 60 fps there is no change in the video.

By courtesy of szlldm, frame blending and motion estimation based interpolation are available for resampleFps in Avidemux 2.8.0 with performance improvements in the latest 2.8.1 nightly. The motion estimation mode doesn't work miracles yet, but miracles are generally in short supply.

i assure you that just for interpolation i'm using a different software and it's working very well. It has 3 different methods: Proprietary, RIFE and SVPFlow (the one i use because it's faster and quality is still good)
i don't know if these 3 methods can be compared to Blend and Motion.

I don't know either, so you should try out, compare and report your findings. Whatever the result, only szlldm would be able to do anything about it.

does he read the forum?

Edit
Motion compensation always makes Avidemux freeze/crash

[eumagga0x2a]

Please use the latest nightly. This crash was fixed a while ago.

Motion compensation qualitywise is in the same ballpark as ffmpeg's minterpolate, but we can utilize multithreading, while minterpolate single thread only.
SVPFlow probably do better quality, but the end result should be compared (i can't).

ResampleFPS + Motion compensation can do 42 fps output (~ 70% of real time) in case of a 1080p sample, doing 23.976 to 60 fps conversion on my 8C16T up-to-date CPU.

while ago? i have the lastest official release 2.8.0

SVPFlow does good job for interpolation but it can add artefacts.
best method i saw is the proprietry of that other software that for what i understood is something between SVPflow and RIFE.
But having SVPflow in Avidemux would be good

i have the lastest official release 2.8.0

Due to lack of affordable time travel, fixes for issues found post-release cannot sneak into it. Please update to the latest 2.8.1 nightly. The last official release is more than 200 commits behind the current development.

edit: the crash in resampleFps in motion estimation mode was fixed on Apr. 17 by this commit.

we simply can not incorporate propriatery code
2.8.1 nightly available here

So how is it possible that the other software could do it?
Avidemux is the most complete software overall for what i need. Now i also understood how to use the queue and even if it's VERY uncomfortable, at least now i can put many files in queue and go to sleep.

It is a proprietary software, right?
Avidemux is open source.
