View Full Version : Scenarist - Subs out of sych - drop frame

I converted a PAL movie with Procoder at 23.97 fps progressive.

I made the pulldown with BatchCCEWS which enables the drop-frame flag.

When muxing back, original audio and video are perfectly synch, but the subs start getting out of synch as the movie goes on. By the end of the movie audio is ahead by a couple of seconds (~2 seconds not minutes).

I know this is a drop frame issue because I can mux with DVDLab, use the same .sst file and bmp's and get the subs in synch if I select "Timecode is written in real time, 29.97 fps".

Or I get the same out of synch problem if I select "Timecode is written in non-drop frame, 30 fps".

How can I solve this problem in scenarist?

Any Scenarist Wiz out there that can help me.

are you making sure drop frame is enabled for your video/audio in scenarist? it defaults to non-drop. also.. what tools did you use to make the sst?

I got it!!

After many trials and errors, I got it, although each trial implied a 25 min muxing :mad: .

You are right, Scenarist defaults to non-drop frame, I tried to change that in the imported video asset properties, (Property Browser Window), but scenarist would say, "The drop type of ..... cannot be changed because it is part of a track."

So what worked for me: before importing any asset, I changed the the settings to drop frame: menu Settings->Default Settings->Timecode Format->(choose drop frame).

That was all, everything n-synch now. :)

To answer your question, I used Subrip to extract subtitles from idx file demuxed with DIF4u.

You can do the same thing in Scenarist without changing the default values by first importing the assests. Then doubleclick on the assets in the data bin and changing their properties to drop frame there. You have to do this BEFORE you build your tracks or scenarist won't let you change them as you found out.
