I need to use the frame counter in order to cleanly edit closed captions in ATSC TV recorded .ts files.
I have submitted a request to provide an option to display the 2 EIA608 closed caption characters in each frame as part of the on screen information. THIS IS VERY EASY TO DO!
In the absence of this feature, I currently parse the file and generate a list of closed caption characters by frame number. This then allows me to know where to place my edit points and align the captions at sentence breaks and no in the middle of a word.
This is working just fine with one exception..and this is really weird! VRD is using the frame number 336 twice! ie: it displays 336 for frame 336 and then displays 336 for real frame 337 and 337 for 338 and so on. This only happens at frame 336! It doesn't happen again in the 30,000 frame files I have tested. So every frame number displayed after 336 is low by one. This is in V2 and the beta.
Does this matter? Well it does if you are trying to edit the captions.
