Thank you for clearing that up!
I’m still a bit curious about the GOP length setting… When I start Shotcut it shows the value 125. When I click the YouTube preset it changes to 15, and I see this is specified in the preset file. When I click any of the H.264 presets it changes to 13, but I cannot find that specified in any of the default preset files so where does that value come from?
YouTube’s recommended upload encoding settings specifies GOP of half the frame rate, but does not indicate what this means for PAL - half the frame rate is 12.5, so either 12 or 13. My impression is that 12 is most used. My PAL AVCHD camera records with GOP length 12 (according to MediaInfo). From guides on internet it seems to me that 12 for PAL and 15 for NTSC are kind of a (de facto) standard. Is the intention behind the GOP length 15 in the YouTube preset to be half the frame rate - but assuming NTSC? I guess it is not possible to create a preset with a GOP length depending on the current frame rate setting? Why is the other H.264 presets using GOP length 13 - why different from the YouTube preset, and if assuming PAL then would 12 more in line with others than 13?
(Sorry if I’m asking too much about unnecessary details here, I’m just curious).
