WebODM VS ReelSteady-Joiner

I've also worked with WebODM but that's more for drone mapping and can be a little tricky to get to work for free.

A better solution would be to use a program that does what most people think of when they hear the word photogrammetry these days, 3D reconstruction from multiple images, and then make an orthorectified image from that.

OpenDroneMap can do that for example.

I like webODM. https://www.opendronemap.org/webodm/

Free, if you install yourself. One time charge of $57 for an installer. https://www.opendronemap.org/webodm/

I use Litchi and webodm with my mini 2. There are instructions for installing webodm on their webpage. https://www.opendronemap.org/webodm/

If you're into open source and self-hosted platforms OpenDrone processes and shares 3D models, orthos, point clouds, etc. Plus it's brandable to your company. It's an amazing bit of app if you're comfortable hosting something yourself/in the cloud.

For stitching I use WebOGM https://github.com/OpenDroneMap/WebODM

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.
