Footage out of sync on export

Hi guys,

 

So compared to my sequence edits. My export is using different parts of footage. This is the 2nd project I've had this issue. I didn't bother the first time it happened but I'm hoping you guys can help point my in the direction of things I can look out for.

 

So my first project it happened on some iPhone footage.

this one is 120fps GoPro footage.

 

What things should I check.

 

fyi I did some searching on internet to try and find solutions. But I keep running into "audio out of sync" problems/ solutions. My issue isn't that the audio is out of sync. It's the export is of a different time code then what is actually in the project.

 

i.e. My sequence might be from 3s to 10s in a piece of footage and the export is putting out 15s to 22s. I hope that makes sense. 

ideas?

What version of Premiere are you using?

 

In general, I think it could be one of two things:

 

1.) VFR media - I've seen plenty of instances of people having trouble with VFR (variable frame rate) media jumping around in editing/export. Premiere does support VFR, and knock on wood I've never had any issues with VFR media myself, but iPhones (all smartphones really now) tend to shoot VFR. You could run the trouble clip through Media Encoder, and make sure you uncheck the "Match Source" box for Frame Rate and manually set it to your target frame rate. This will make it constant frame rate media. At the very least even if VFR isn't the issue, if you took the trouble footage by itself and created new files and replaced those in your edit, it might solve the issue regardless.

 

2.) Could be variance between your sequence frame rate and export frame rate. I dont think this is it, because usually at most this would only cause variances by a frame or two, but for best practice make sure your sequence timebase matches your export timebase. Otherwise, what you're seeing in editing is not 1:1 to what you'll get on export.

The other thing I've seen is that Hardware Encoding can cause the issue of the different video lengths on export.

I'm using the latest version of Premiere Pro it's updated to whatever is the current version.
The second occurrence was a clip with  120fps GoPro footage. I'm using proxies because my computer is not as powerful as I'd like. The problems are more than likely non-related. i.e. iPhone footage vs goPro footage

with the GoPro footage it's 120fps and my sequence & export are 24fps. I have some clips in the sequence at "20% speed/duration". Both speed clips are mislocating the footage.

I'll try your recommendations, VFR & using/checking settings in media encoder. I might also try looking at media info, turning off proxies. maybe even doing a new project and trying to replicate the problem.

Hoping I can get to the bottom of it. Rather annoying I must say.

Appreciate the response mate. gives me a couple of ideas for sure.
