Premiere Pro Mismatch - Export is 3 Secs Longer Than Sequence Duration
on Oct 17, 2017 at 1:39:32 am

Hello everyone,

I have an issue here with PP CC 2015 - or maybe I do not understand frame rates / time codes correctly.

Here's the PP project info:

> PP sequence setup is 23.976p
> all footage used in the sequence was shot at 23.976p
> timeline in the sequence shows a total duration of 00.39.59.19
> when I export the video as 23.976p, it then shows a duration of 40 mins 2 secs in MediaInfo - a full 3 secs difference
> VLC player shows a duration of 40 mins 2 secs as well when playing the file yet the time code that was burned into the exported file shows 0.39.59.19 on last frame...... (?)

When I import that PP video file into Pro Tools into a 23.976p timeline it shows a duration of 0.39.59.19, but when I click on video properties I see 40 mins 2 secs 19 frames...

What am I not understanding here ? Shouldn't these SMPTE timcode values refer to the actual length of the sequence depending on the frame rate setting ?

Why does the total duration of my export differ from what was stated in the sequence timecode ?

Thanks !

Could you post a screen grab of your export setting dialog window with your settings?

Weird. It sounds like a drop frame - non drop frame issue. Which shouldn't happen.

23.976 fps video uses timecode running at 24 frames per second...so there is a discrepancy.

Back in the NTSC world, the discrepancy between 29.97 fps video and 30 frames per second timecode is dealt with by using drop frame timecode.

There is no drop frame timecode in the 24 frame world. Its all non-drop frame, so you are seeing the result of that inaccuracy.

thank you.

shocking that there is no adjusted display when it comes to sequence duration.

Yeah, Avid has this...the ability to see the 23.98 sequence with 29.97DF timecode. It would be nice if Adobe did the same.
