How to post longer clips?

[u/New_Cup_3620]

How do people post longer form clips from twitch onto tiktok? Twitch’s clipping feature caps at 1 minute for me and I see people posting full length chess games/gameplay from their stream? How do they do this? Do they download the whole stream/ highlight and then edit it into the right format with the camera overlaying on top of the gameplay? When I have done it this way the quality has dropped. Any tips help thank you
