ReelSteady-Joiner VS gyroflow

What's the best way to combine these files to a complete MP4 while keeping all the metadata intact? I did a bunch of google searches, but all the methods I found completely screw all the metadata / additional data streams in the file. I've tested "ReelSteady Joiner" (which just runs ffmpeg in the background), I've tested ffmpeg and udtacopy as suggested on the GoPro Labs page, I've tested various different ffmpeg versions and commands I found through Google.

The easiest fix is to get this program: https://github.com/rubegartor/ReelSteady-Joiner

If you want to stitch these files together and retain gyro data for stabilization, download and use this tool. It will do all the work for you and output a single, big file.

I am no videographer and only read somewhere about gyro-stabilization and https://gyroflow.xyz So maybe that's an alternative to that software. Just leaving it here.

You can get pretty far with Rust + Qt and I've been very happy with it, see Gyroflow

I need some math in Gyroflow for lens geometry and lens projection if you have experience with that

Rust has quite decent support for QML though. One of the really famous video footage stabilizer apps uses Rust with QML: https://docs.gyroflow.xyz/app/technical-details/used-technol..., and that is a non trivial UI: https://gyroflow.xyz/

I think you would get the same result if you just recorded a regular video (at whatever resolution you want and a minimal framerate), then pass it through something like Gyroflow and increase the speed. Downside — it’s not automatic and you can’t preview on the camera. Upside — it won’t overheat you have more options to tweak after the fact.

My buddy and I have been playing with Gyroflow (free and open source) for stabilization. It uses the A7C's gyro data to smooth out handheld footage. There are a ton of options to play with, too - much more to work with than Resolve, which is what we had been using. We've had solid results on the A7C and excellent results with the BMPCC6K.

Maybe it wouldn't be a bad idea to dig into the Gyroflow's sources.

You can convert that data into a CSV using Gyroflow in combination with this Python script.
