Dear Community,

I produced a video for use in academia last year. The video is screened with a transcript that runs alongside it. I was recently asked to change the spelling in one of the names in the credits. Simple, right?

I don't have the original media files on my drives, so I was going to use the H.264 version of final out put file and create new credits in Premiere.

However, when I executed this, the final film (a 58 minute film) came out 2 seconds shorter. I did not realize this and sent it back to them.

They replied that now their transcript is off, and they need the film in the exact same length.

I went back and imported the final H.264 file into Premiere. When I do so, that file, which is 58:41, turns into a file that is 58:39. Any idea what is going on?

Thanks.

Check the frame rates and match the rate of the original file in the timeline and in your export settings.

Thanks, Joe.

The client sent me specs for the file they are using. The frame rate is listed at 23 frames/second (see first screen grab, please).

The second screen grab, which lists the file length as 58:42, is off my own computer. It does not show frame rate, but when I import into Premiere, it says the frame rate is 23.98. I have also pulled it straight onto a timeline, and selected "change sequence to match clip settings" and it still comes in at 2-4 seconds shorter than the 58:42 listed on the file info. This makes me think it's not the frame rate.

Thanks again for any help solving this mystery.

Try converting your frame rate to 23.00fps, instead of 23.98fps.

Thanks...do you mean I can change the frame rate when I import the file into my project? How is that done?

Or to change the frame rate of the sequence? I don't see a 23.00 fps option in the sequence settings. Please see screen grab below.

Or do you mean when I export the sequence? I don't see a way to set it to 23.00 there either.

It's so strange that a file that says it's 58:42 outside the project reads as 58:39 inside the project. Can anyone explain this? I feel like the problem starts here.

And here's another odd thing: the file in my project, which says it's 23.976 fps, when put into a timeline, which also has the setting of 23.976, is only 58:35:13 long.

Thanks for any help -- I'm getting desperate!

Maybe it is the difference between drop frame and non-drop frame time code.

BTW -- I have tried several other files that are longer than about 20 mins and they all lose a few seconds when imported into my project. Thank you .

When the clip is in the source monitor, right click on the Timecode display, the blue or yellow numbers in the lower left of the source monitor. This will tell you what the clip is recorded in, DF or NDF.





Here is a clip from Adobe's site that might help.

Good to know...with this clip both drop frame and non drop frame are greyed out. About to pull this baby into FCP 7 and see if I can get any satisfaction there. Thanks!

I imported in FCP, and am getting the same result -- the clip is a few seconds shorter. I have tried several clips, and it seems like every clip I import is a different length in Premiere (and FCP) than it is when I hit apple-i on my desktop to see the length.

Is it possible that this is always the case (clips change length when imported into projects) and I just never noticed? And if so...do I have to tell this client it's impossible for me to send them a clip that's the same length as the last one I sent them? Thanks again.

I have a feeling that the original files was set to 23.00fps which is a computer frame rate and not a true video frame rate (23.98), so it is always going to be a mismatch when bringing it into a video edit system.

This would also be why it won't read DF or NDF timecode, it is a non-standard format.

With PP CC 2015 there's a new feature for changing duration:

I have premiere pro 2014. This would be a nice option, though. Still might not end up in sync with the file they have, though. Thanks.

Thanks Yair, I updated to 2015 and tried this...these are the settings I used. The ensuing file was 58:45... Does this function tend to not work very well? Thanks

I have no experience with this new feature.
