I've come across a problem and I can't find the solution. The problem: after exporting my video and audio form premiere pro they aren't in sync anymore. while they were in sync in the timeline in Premiere Pro. I believe the problem doesn't have to do with variable frame rate, because the frame rate is constant. I have the last updated version of Premiere Pro (14.3.1.), so bugs shouldn't be a problem either.
When I export I pay close attention to my settings. In this case I used the following settings: H.267 - Match source - High bitrate. (i've also tried others.) While exporting I made sure that the frame rate in the export (25) settings is aligned with the frame rate of the video I recorded (25), so this shouldn't be a problem.
To be clear about the result after exporting: In my Premiere Pro timeline the video and audio are both 1:45 seconds long. After exporting the audio is still 1:45 seconds, but the video changed to 1:24.
Does anybody have an idea about how I can fix this problem? Your help will be very appreciated!
If that doesn't work, try resetting the Workspaces: Reset a workspace Reset the current workspace to return to its original, saved layout of panels. 1. Do one of the following: • Click the Workspace menu icon and select Reset to Saved Layout. • Choose Window > Workspace > Reset to Saved Layout. from here: https://helpx.adobe.com/premiere-pro/using/workspaces.html
If that doesn't work, try Preferences > Audio Hardware and set Input to None.
If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.
If that doesn't work, try creating a new project and import the old one into it.
