Stabilization better than davinci

Hi, i need help with stabilization a video: I tried already Davinci and Cuvista (github software) and it did not do the job good enough. Either it doesn't stabilize the image enough, or it creates artifacts, or it crops the image too much. So i wanted to ask you guys, if you have any advice ? The video is 4k120fps. So it has to work for such a task. I have rtx5080 and intel 13900k and 32GB CPU RAM. So i cant use one of these researcher-models where you need 100gb for 480p videos. Gyroflow dows not work good (artifacts). I guess the reasion is, that i want to use my smartphone-camera-app and i cant disable OIS. but i need to use the camera-app, because blackmagic oder motioncam can't use all my camera-features. And i'am using a scope on my phone with a special case, where you can mount the scope directly over the lens (it does not wobble or so, it is very stable). Please no discussion, about gimbal or sth like that. Its about stabilisation afterwards.

Does anyone has any idea?
The Video is uploaded.

Edit: I also tried vid-stab-gui, but all these "classical" things are not working good enough. I tried "Stabilization Camera" (android app), and it did the best job so far (basically no artifacts, but the stabilization-effect could be a bit better). Problem: It needs like half an hour on a high-end smartphone and on pc i can't use it with full perfomance of pc (i even tried android on windows and emulators and such stuff. but it does not work good).

StabilizeIT (AviSynth/VapourSynth)

Code:

clip = fromDoom9.StabilizeIT(clip, div=1.00, rotMax=0.00, thSCD1=8000, thSCD2=2000, cutOff=0.01, anaError=100.00) clip = core.std.Crop(clip, left=112, right=112, top=88, bottom=80) # cropping to 3616x1992 too lazy to check the minimal crop values ;)

seems fine,... (I used VapourSynth, but the same can be done with AviSynth)

The Vapoursynth script seems fine to me.
Does the Vapoursynth Preview report an error? If there is no error, does replacing the "C:/Program Files/Hybrid/64bit/vsfilters/Support/libmvtools.dll" with "C:/Program Files/Hybrid/64bit/vsfilters/Support/libmvtools_old.dll" fix it for you?
If there is an error message, what does it say?

Ps.: Also try latest dev.

Like I mentioned, I used:

Code:

clip = fromDoom9.StabilizeIT(clip, div=1.00, rotMax=0.00, thSCD1=8000, thSCD2=2000, cutOff=0.01, anaError=100.00)

Divisor 1 and cutOff=0.01 might slow things down.
You might get away with different settings, but you will have to test that.
0.6 fps seems too slow, I got:

Code:

encoded 570 frames, 82.48 fps, 42049.44 kbps, 23.85 MB

(encoding with NVEnc+AV1)
The whole script I used:

Code:

Atm. you are using:

Code:

clip = core.lsmas.LibavSMASHSource("C:/Users/Gaming-Tower/Pictures/LocalSend/Stabilisation-Tests/Hybrid-Test/VID_20251101_135145.mp4")

You might want to enable hardware decoding, by either:
a. using DGDecNV
b. using LWLibAVSource with libav hardware decoding mode 1
c. using BestSource with i.e. opencl or cuda
atm. you do the decoding of the source through software decoding.

Ps.: also test the latest dev, it probably has another libmvtools.dll (which works for me and is faster)

@Plantos: Happy to hear the dll in the dev worked.

About the SVT-AV1-HDR development branch:
No, I plan on waiting for the changes from there to hit the mainline. That said, if you build a binary from that development branch yourself, you can replace the existing one with it and add the new options via 'STV-AV1=>Advanced=>Custom addition'.

Abput NVEncC:
NVEncC has none of the tune options that svt-av1 has, since those are:
a. defined in the standard
b. not offered by the encoder chip
You can see the available options of NVEncC over at: https://github.com/rigaya/NVEnc/blob/master/NVEncC_Options.en.md

StabilizeIT does not offer automatic cropping.
Like I did in my example, you will have to crop manually.

side note: There are autocrop functions for both AviSynth and VapourSynth, but afaik those will not help. Their goal usually is, to remove black bars only as far as possible while not to remove active content.

Out of curiosity: can others posts examples what other tools produce of this clip in regard of stabilization?

Mercalli, Warp

It would be better to give less stabilization, because you can see how it turned out.
Additionally, at 60fps the image would be sharper and easier to stabilize.

@rgr: thanks
