Musescore sharp - OBS blurry - SOLVED

• Jan 30, 2025 - 13:10

Has anyone tried to use the OBS "start recording" feature to record Musescore while it's playing the score and had/solved the problem that the OBS recording is not as clear or sharp as what one sees on Musescore?

I've looked at various OBS posts about text blurriness and have tried:
> OBS > Video > General > Base and Output resolution are the same (1920 x 1080)
> OBS > Output > Simple > Recording > Recording Quality > Indistinguishable Quality, Large File size
> OBS > Output > Simple > Recording > Recording Format > mkv
> OBS > Output > Simple > Recording > Video Encoder > Hardware (QSV, H.264)
> Windows > Display > Scale > 100%

I'm using a Lenovo P1 Gen 3, i7-10850H, 32 Gb ram, Nvidia Quadro T1000 with PC bios set to with Graphics Device set to Discrete Graphics.

I've fiddled a little bit with anti-aliasing in the Nvidia Control panel to no avail.

Here's two images: one showing the resolution of Musescore and the other showing the blurriness of the OBS video recording.

If anyone has dealt with this OBS blurriness issue (several posts on OBS forum dealing with blurriness), I would be interested to hear.

SOLVED (good enough)

I was able to get sufficient improvement of OBS recorded text by assigning the Quadro T1000 graphics processor to OBS as outlined here:

https://obsproject.com/kb/gpu-selection-guide

> Windows > Settings > Display > Graphics settings > browse > find obs-studio executionable > Options > select High Performance

---> OBS recorded output was sharper!

Also added OBS filter to increase contrast +0.2, lower gamma -0.7. That made the text a bit sharper.

Windows Task Manager showed GPU usage around 30%. Lots of GPU processing left.

Whew! What a bother!
