How do I trick my GH5/4 into playing back exported .movs transferred to SD?

The long title says it all The file shows up in the viewer when named according to the cam system, but I get an error message "this motion image can not be played". I exported 4k, 24p, h264 from FCPX, using GH5 footage. Need the illusion as a prop for a shoot. Can it be done?

There are two ways to do this.

The NASA spending millions on a pen to write in space approach or the Soviet using a pencil approach.  (Yes,yes, I know thats turned out to be an apocryphal story but I like it anyway  )

The NASA way would involve copying and renaming files (there is a catalogue file hidden away in a Panasonic folder on the SD card) and using a hex editor to append chunks from a genuine file and trick it into thinking it came from a Panasonic camera. I've just spent some time doing this and managed to change the error but not much else so you'd need to dig a lot further in. Another NASA approach would be to use a tracker in your NLE to graft the video onto the GH5 screen.

The Soviet way would be to play the file you want on an iPad or some other screen and just film it with the GH5. No hacking, no plugins, no rendering.

Its up to you but I know which route I'd choose, tovarich.

I'm guessing that the profile level, keyframe distance, reference frames, etc. aren't matching what the camera records in. I use a program called "videoSpec" on my mac that tells me all this, so use that to figure out exactly the settings to export from compressor (by dropping in a file you shot on the camera), and it should work fine. Just make sure to put it in the right place on the sd card.

Thanks for the great replies guys. The Soviet way prevailed.
