Describe the bug
Found two issues with the subtitles after the last update

• The subs are no longer in sync if you trim the video. The subs always start from time 0 which causes a desync if you have a trim that has a different start time than the original video.
• The subs are always centered with respect to the original dimensions of the video. If your crop is not centered the subs would be cut off.

Software version(please complete the following information):
v3.40.4

I attached an example using the video from #93, you can see there is like a shadow where the subs are supposed to be and also the timing is wrong:
