Audio synchronization issue with Highlights video on export
I've created a highlights video for one of my streams, which clocks around 30'
The video plays correctly on Twitch, but when I try to export it, either by downloading or by uploading to Youtube, at certain points in the video the image freezes, while the audio keeps rolling, which causes the whole thing to desynchronize.
I suspect the cause might be highlight clips that are too close together, or too short... Or maybe I have too many highlights.
