i need to record my screen for more than 30m for free, what should i use and how do i use it

https://obsproject.com/ I think this works.

If OBS is going to be either too laggy or unusable for you, you can also try Movavi, though it slaps a giant watermark at the center of the screen. Movavi is very good when it comes to performance though

I use the Xbox screen recorder. It’s free I guess. It’s also on PC

if you have win 10 on your pc, use xbox game bar (win + g) if your on old os (like win 7, 8) then idk

best bet is to just use obs. fiddle with the settings until you got what works for your setup

i think im gonna use movavi cause my school owns my pc (oof) and movavi somehow works so thats fine :)

good for you?

Yes, I would also recommend OBS to screen record your PC, it is free. I tried to use Xbox Game bar, but it looks like it only can screen record gameplay, when I exit the game and it will automatically stop recording, is my method of operation wrong? If you think OBS is very hard for you to operate as it's unfriendly interface, there are some tutorial videos on YouTube, and you can use Joyoshare VidiKit, this software is very professional and easy to use, but free to screen record for 1 minutes.

@Nora96 I'm pretty sure OP has found a screen recorder in the past 4 months

ObsStudio is best for this

Based on my experience, OBS Studio is perfect for screen recordings, including in-game streaming. :)
