    Hi everyone,
    new to FFmpeg and muxing remuxing stuff.
    I have Qoocam 8K 360 camera which creates MOV container with 2 video tracks and 1 audio track. Camera also, presumably, creates metadata with on board sensors for stabilization and orientation purposes (perhaps even more proprietary data).
    I own Video Enhance AI software from Topaz Labs and I would like to:

    1. extract both video tracks
    2. enhance quality of those tracks (in Video Enhance AI)
    3. replace those two video tracks in original MOV file
    4. Stitch in Qoocam Studio to create equirectangular enhanced video file.

    Is there any other way to achieve better AI quality of the video?

    Enhancing stitched equirectangular footage creates artefacts at nadir and zenith areas because Topaz Labs products are not 360 aware.

    extracting all tracks:
    ffmpeg -i in.mov -c copy -map 0:v:0 out_0.mov
    ffmpeg -i in.mov -c copy -map 0:v:1 out_1.mov
    ffmpeg -i in.mov -c copy -map 0:a:0 out.wav

    combining tracks together (metadata is missing in Qoocam Studio error), this way the file isnt recognized in Qoocam Studio:
    ffmpeg -i Q360_20201108_135512_000000_track0.mov -i Q360_20201108_135512_000000_track1.mov -i audio_0.wav -c copy -map 0 -map 1 -map 2 output.mov

    Code:

  2. ffmpeg can copy some types of metadata

    can you identify any metadata in the source ? Try mediainfo, exiftool

    Or do you know where the "metadata" is - is it a separate track, embedded in video bitstream etc.. ?

    It might be helpful to post an unprocessed source sample

  3. Try upscaling with nnedi3_rpow2
