Yes, I am hoping to add a 30 second video to explain the whole process. Basically you upload a srt file in the first screen and then match any 3 subtitle text to the correct time (as determined from watching the video).

Based on that information the script calculates the discrepancy in the frame rate or time shift by comparing it with the original file and then fixes that for you (also gives you two different versions if more than one solution fits)
