Raspberry Pi Global Shutter Camera files

I have been experimenting with a new camera; a Raspberry Pi 5 with the new Global Shutter Camera module. I am doing this to record fast movers (Rockets) without shutter roll. Global Shutter cameras' video is like a high speed photograph where each frame is geometrically stable. This affords stabilization in POST without distortion.
It would be great to import these video files directly into DaVinci Resolve: .h264 and .raw

You need to the remux the raw h264 stream to something Resolve can load. Here is the relevant section in the Raspberry documentation:

The point to get DaVinci Resolve to import these files directly is to avoid the time consuming and interim steps that causes loss of resolution and dynamic range. There is so much to suspect that image quality is lost when converting one h.264 file to another h.264 file, never mind multiplying the file count.

FYI. The .mkv recordings will mount in the timeline directly without conversion.

Update to RPi Global Shutter Camera files. Succeeded in recording 1456Wx1088H, 60 fps, 10 minute video .mp4 file without dropping any frames. This file imports directly into DaVinci Resolve. Will soon test recordings of fast moving objects for stabilization in post.

Re-muxing does not affect quality, it just adds/changes a container.
