Technical question about the Rollingshutter correction

[c-r-o-n-o-s]

Hello.

I have a question about processing videos.
My "camera" has a hybrid shutter.
The normal photos that I load into Metashape are seen as with a globalshutter.
For videos the rollingshutter method is used.

When importing video frames all Exif data is lost. (Or are not present in the video at all).

Does Metashape not need the exposure times of the photos for the "rolling shutter" correction?
(Or can I improve the correction by adding the exposure times manually?)

Thank you!

Regards
