File cant convert to mp4

For me, it seems like loosing time to encode 3 times. Shocut, Handbrake then youtube.
If you really want to do it, tou should use Shotocut in a loss less setting.

5Go is for a clip which propoerty?
Duration? 1080p? 50 fps? which Settingzs in shotcut (I presume you use “Youtube” pre set?)?
