The freely available video stabilization software is in the beta phase with limited features. It handles basic stabilization tasks very well when the parameters are set correctly. Features like the rolling shutter effect reduction will be provided in future versions.

The video stabilization program features a new operational concept where video stabilization occurs before the video cutting process, using a program of your choice.
V0.2 Windows
The camera flow is displayed graphically, including the camera flow filters and the distance between the image edges and the desired image section for each individual frame. This means you can quickly find the optimal filter setting for the video without having to watch the video or re-analyze it.

As a highlight starting with V0.3 parts of the stabilized video can be improved by manually overwriting camera path lines for the optimal stabilization result. Sections with low motion can be stabilized like a tripod shot and moving scences can be stabilized to look like smooth camera wagon clips! The good adaptive filters from V0.1 described in the next section cannot come nearly close this new approach.

There are two adaptive filters to choose from, which in many videos increase the filter performance in quiet phases and weaken the filter performance in turbulent phases so that no image edges are visible in the desired image section during fast movements.
In the t5.json project you can see the use of adaptive filter type 5. From frame 2300 to frame 2700, the filter performance was massively increased. Before and after, the red line differs from the black line, which reduces the filter performance so that no black edges are visible in the crop (image section). If the black line falls below 0, it means that image edges can be seen in the exported video. The red line shows how much the strong filter would show the edges. Unfortunately, at around frame 1970 and around frame 2000, vertical edges can be seen in the exported video. From frame 2820 the video part is probably unusable.
The Version >= V0.2 now does provide a silent, fast and smooth Video Player where you can watch the stabilization result before exporting the video. On my PC a with an Intel 9400I CPU I was able to playback a on the fly smoothed 4K video up to 30 fps and FHD up tp 90 fps.
Average memory usage while stabilizing or exporting 2.5GB RAM
Windows 11: 8GB RAM, ca. 200MB hard disc space (without NVIDIA GPU-Accelleration)
Older Windows Versions: high likely yes, but untested!
Linux with Wine: Yes, but the fonts look mediocure.
Unfortunately, version V0.4 cannot copy the audio track, the exported video is silent!
The stabilization with zoom, perspective and homography are not yet available in this version. These generally deliver worse results when recording videos with all stabilization programs of moving objects.
An advanced, paid Professional Version is currently in development, set to include the following features:
Special thanks to all my supporters which enabling me continuing this work!

The operating system must be up to date to use this software! After the download you can extract the tar archive and install the program in the download folder with the call
pamac install freestabilizer-pkgver.pkg.tar.zst FreeStabilizer
For the Linux version it is allowed to adapt the application dependencies with the system calls patchelf + readelf to get FreeStabilizer running on your Linux operating system without any warranties. Following package dependencies are required: mkvtoolnix-cli openh264 qwt opencv qt5-base
V0.4.1 First Linux version + bugfixes for Windows
V0.4 Improved Manual camera path editing, Bugfixes
V0.3 Excellent Manual camera flow path editing added.
V0.2 Preview player integration, improved start and endings, dark theme.
V0.1.1 Windows facelift version with a total custom style.

V0.1 Initial Version with native operating system styles, uses only 1.5GB RAM.
Yes, for the new Mx processor series (>= M1).
Tip: You can run the Windows Version on a new 64 bit Wine (Windows Emulator). For X86 MAC Systems there should be no performance issue!
No, because a relatively new OpenCV library is required!
I'll make them here directly or with links available as soon as the release versions are ready!
Tip: You can run the Windows Version on a new 64 bit Wine (Windows Emulator).
