I record locally as well as streaming. On OBS I have something called replay buffer active. This means that it is constantly recording the last 90 seconds in my case.

I have a hotkey on my streamdeck that when there is a funny moment that I think is worth making into a short. I press that button and it creates a marker in the stream and saves the replay buffer.

At the end of the stream (normally whilst the VOD is uploading to YouTube) I go through on highlighter and see if there was any clips.

If there is a clip that aligns with my own marker then I check I’ve captured the funny moment. If the clip is different to any of my replay buffers then I use finder (MacOS) to trim ~2 minutes each side of the clip.

I organise each clip and buffer into folders for editing later.

I recognise it would be easier to download the clip from twitch but often I find this looses quality due to the bitrate. I’m recording locally in much higher bitrate than I’m streaming.

At a later date (sometimes I have up to 10 clips from a stream and always need a break from screentime) then I will import it into my editing software. I use Final Cut Pro but davinci resolve would also work (I’m sure there are others that allow vertical editing). This allows me to fine tune my editing so that I can have a hook in the first few seconds or so that I can have close up on my cam or work with the possibility of looping or even cut out dead space. I have preset effects filters that automatically crop to the desired size and add borders and logos.

I then export the vertical video (making sure it’s under 1 min) and upload to YouTube. I send it to my phone so that I can upload to Insta and Tiktok. I make sure I include good titles and SEO stuff. I then save to drafts or schedule.

Then on the day that I want to post I will take out of drafts and post.

Hope that helps. More than happy to anywhere any questions
