SCC Captions Frame Rate

[Gigot]

Peace to all!

Could anyone please tell me why my SCC is shown as being 23.976 in Subtitle Edit (on Windows), but both Media Info and Premiere consider it to be 29 fps? I had originally converted it from an SRT and subsequently fine tuned it in Subtitle Edit, synching it with my 23.976 video in that app, and all seemed fine but when I tried it out in Premiere it played out of sync (drift).

I tried changing Premiere's Indeterminate Media Timebase setting to 23.976 but it still lags a few seconds towards the end of the movie. Please help me to understand why this is happening and especially, how I can be certain it won't happen in other streaming platforms.

Thanks so much!

Open it in Notepad or some other plaintext editor. Check the timecodes along the left-hand side. They're displayed in the format 00:00:00:00 or 00:00:00;00. That's hours minutes seconds frames. If any of the frames values are larger than 23, it should be rendered as a 30fps caption. For the most part, the effect will be captions that each begin at the right time but end early.

If you want to upload the scc for proofreading I can maybe tell you what's wrong. I’ll also need to know the duration of the actual video.

Is the default frame rate set to 23.976 in "settings"?

Thank you very much. It seems like the SCC is not synched properly because I used a downloaded video as a reference in SE instead of the original. I was told to import the original video into SE and do a point sync. Another person told me to convert the file to drop frame with SMPTE in SE. Please tell me what you think of those options.

*I just imported*my*original video (copied from my HDD and downscaled with Handbrake) together with my*SCC in Subtitle Edit, and they matched perfectly. So it seems like my SCC was good already, and uploading*it to YouTube gave bad sync results because of whatever the* YT processing does to videos.

I wish I could double check it in Premiere, but Chat says Premiere is not a good test grounds for OTT and I learned that the hard way!*I guess I’ll have to trust the sync I’m now seeing in SE as a final assurance. Does that sound good or should I try to play on VLC or somewhere else to be sure it will be in sync for OTT?
