GoPro "Highlights Tags" / Chapters

Resources
1

hi,
i can use a Gopro 9 of a friend and found this nice feature, witch i can mark “Highliths” while filming.

now. i can’t see any option anywhere to use those markers in any application. Only a automated Highlight Video is generated from the GoPro Cloud.

when i open a Video in VLC, i can jump to the Hilight Tag via “rightclick”->PlayBack->Chaper->(1,2,3…). so those Tags/Markers are in the Mp4 File.

is there a way to get those markers in shotcut and insert Markers?
or does anyboddy have a usefull easy “workflow” or “Lifehack”.

this woud massivly improve my editing speed for the Floorball Highlight videos i create for my Kids

instead of waching the complette machted to get special Moments

thank you
Steeve

Use another player including GoPro Player, go to a highlight, note the time. Now, in Shotcut, go to that time (there is a keyboard shortcut) with the clip in the Source player. Keep in mind that most players do not use a full time code with a sub-second field counter and might only show minutes:seconds. See the bottom of this page for more info about entering time:

Thank you for your help.
i’ve found a pythonscript witch extratcs the Times for the “Highlights” on Blaming GoPro-Highlight-Parser/GP Highlight Extractor.py at master · icegoogles/GoPro-Highlight-Parser · GitHub

I found there is another way to get these times using ffprobe that is already included with Shotcut from this GitHub Issue

I just tested it with my Hero 11 Mini, and it worked for me:

$ ffprobe -v error -show_chapters -of default=noprint_wrappers=1:nokey=1 -sexagesimal -select_streams v:0 -show_entries chapter=start_time -of csv=p=0 GX010071.MP4

0:00:14.197000
0:00:27.827000
0:00:53.136000

It also works with the .LRV proxy.
The time values it outputs are similar to Settings > Time Format > Clock menu option. But even if you do not have or use that, you can still manually copy and paste the times into Shotcut Timeline Markers for a workflow like:

  1. Add video file to the beginning of a track
  2. Run ffprobe command (See Export at the Command Line for how to use bundled command line utilities.)
  3. Copy a time
  4. Click Shotcut’s timecode display below the player, or switch to Shotcut and press Ctrl+T
  5. Press Ctrl+V to paste and Tab to seek and clear focus
  6. Press M to add a marker

Tip: Learn to trim directly on the timeline using shortcuts including variations to ripple shown in Timeline > menu > Edit.

P.S. Yes, it might be good to integrate this feature somehow, but that should actually create clip markers instead of timeline markers, and Shotcut does not yet have clip markers. Shotcut already has File > Export > Markers as Chapters; so, it should probably add a feature to import a chapter text file to timeline markers. However, even that is not a great fit. A quick feature addition is Properties > menu > Get Chapters that runs ffprobe in the background as job. When done, the job in Jobs shows these times in a text dialog like we use for various job functions.
