After a few months I’ve managed to make an app that convert osu replays to mp4 videos in few clicks.
All you need to do is to choose the replay you want to convert and click the "Start" button.

You can download the app here:

Amazing feature :D
Not DT Farmer
wow it seems useful
I love you.
absolutely legendary. replay channels and users alike will remember this forever. Thank you!
This is insanely good work! bravo

Just tested it myself rn and it worked great. This has been talked about forever but never made so massive credit for finally doing it!!!


Edit: I just had a random crash with no error message? may have just been my system or a bad map. Also I'd suggest making .mp4 the default export if possible since its more often used and people are more familiar with it

great work nonetheless!!!

Edit2: Ok i found a problem

I realized for some reason (even though i disable mouse input in game), it appears as if i click and use mouse 1 every now and then, it isn't a massive problem, but an issue none the less
i remember we had one of these at some point, but its sadly abandoned now, glad to see people come back to it again, i really like the idea
thanks for doing this <3
Umm Hello, i got problem when i choose my osr, when i click open the program closed, and then i got error message how i fix this?
This information is worth millions.
That's actually really handy ! And also weird because i was wondering about something like that last nigtht haha what a coincidence :)

I found out that you have to switch to another skin, for example using default osu skin solves this problem
this tool is actually insane, thanks for developing it <3

this is going to save me a lot of time and hassle with uploading replays

Fixed, click on the update button.

And I'm here thinking .osr can't be converted into .mp4...

This is interesting.
App lags upon clicking start for newest detected replay exported, after few seconds showing information about timeout error, app will force quit itself upon accessing settings tab; is there any way to fix it?
