Subtitle not in sync

I'm going to assume that the issue is with the video file and 'not' convertxtodvd, but I thought I would post just in case. The video file and subtitle "is" in sync when I play them on my desktop computer, but not after conversion and when I play the finished DVD in my standalone DVD player. Windows 10, Verbatim DVD-R's, latest version 7.0.0.73.

Thanks in advance, log attached

In most cases problem is due different framerates.
Every second timing of subtitles drifts more off when this is the case.

If they "jump" off and then stay same amount off then those subtitles are for different version or video file has been edited.

Yes, did you do any editing to the source video to remove content before importing it into CXD? If you did, then the subtitles would be out of sync because the video file is not the same size anymore. You probably didn't edit the source file, but I'm covering all the bases.


Or, did you use the trim function in CXD to edit out video footage? I don't know, but I wouldn't think CXD would also edit the subtitle file to match the changes to the video. It might, but I would tend to doubt it. I just don't know for certain.

Thanks for replying, no I did not edit the file. FYI, the subtitle file was included in the over all mkv file. Did not 'find' or use a different subtitle file, which I do from time to time when a video file doesn't come with one. Just thought it was 'odd' that the file played just fine on my desktop PC but after conversion the 'file' was out of sync.

That's it. Found another 'video' file, something I usually do when something doesn't work right, and it converted just fine, no issues.

Thanks again for the input.

Stay Safe.

Yes, it was sounding more and more like the source file was the problem to begin with.

On computer file is usually played at fps that is was created to be played and player checks that frames are played on correctly.
On DVD it is played according equipment specification, and that might be totally different, causing small drifting (23.97 vs 24 for example)
