Screen shot problem

when i take screenshot scene with subtitle , the subtitle doesn't appear in the picture
this problem suddenly appeared

With the default video renderer (EVR-CP) screenshots are always without subtitles.

If you select MadVR as video renderer, then you can include subtitles.
madvr options > rendering > screenshots

How i can make madvr as video renderer

MPC-HC options > playback > output > Directshow video > madvr

It worked thank you but when i connect the laptop to the tv by the projector , the video become kinda slow or something like vibrate

Madvr requires a (more) powerful graphics chip than other renderers. Certainly when outputting at high resolutions.

You could try these settings for better performance:
Madvr options > scaling algorithms > image upscaling > DXVA2
Madvr options > scaling algorithms > image downscaling > DXVA2
Madvr options > scaling algorithms > chroma upscaling > bilinear

Thank you very much it worked now
