Hi Nikse
See the attachment. It's a 4 line srt file. For convenience purposes, each line has it's start time, end time, and duration as text.
For people to be able to follow I'll put SE's list view:
Then export --> xml/png. Set framerate to 23.976 --> Export all lines. When opening the xml/png result in BDSup2Sub, timings get more off further in time. I took 4 screenshots from BDSup2Sub and put them in one image:
I don't know if you use BDSup2Sub internally, but it has a framerate bug. r0lZ, the creator of BD3D2MK3D, informed me about this in his software's thread. You can read more
here.
A way to force BDSup2Sub (the standalone I use) to output correct timing info is, in "Conversion Options" window, to tick "Change frame rate" and set both "FPS Source" and "FPS Target" to 23.976. See screenshot:
It has something to do with a default framerate that the program would assume, so my guess is that it's not a "specific 23.976 fps"-bug, but more framerates suffer from this.
I will test further for SUP output timings.
For now, cheers
