Audio Desync

[PawButtox]

Hi,

I stream to a platform called Twitch and after I finish streaming I download the VOD from twitch. I stream at a constant bit rate of 3000 and at 30FPS but when I import the footage into Premiere pro the Audio is completely out of sync from the video! I've done some research where Adobe employees say that Premiere Pro supports constant and variable bit rates. I've tried everything possible and my only solution is using handbrake to convert the file which is not exactly helpful as it can take a while. Is there a way to get the audio to sync within Premiere Pro without using Handbrake?

Many Thanks,

Mark

Exactly what is INSIDE the video you are editing?

Report back with the codec details of your file, use the programs below... A screen shot works well to SHOW people what you are doing - For Windows Internet Explorer press the PRINT SCREEN button on your keyboard, and then do CTRL-V to paste the screen print from the clipboard into a forum message

- when you analyze your file in MediaInfo and post a screen shot in the forum, do so in TREE view

Premiere Pro doesn't work well with some types of variable frame rate video.

Transcode with Handbrake before importing into Premiere Pro.

Here are links to Handbrake tutorials:

I have notice similar problem BUT...I noticed something different. 
I download VOD which is already muted in some parts. I can see that when I import it to Premiere, then move to timeline...it removes all the muted parts and that's why video/audio is desynchronized. 
Then I can see that at the end of the audio track i have silence...it's like moved to the end.

Any idea how to prevent premiere to do it by itself?

I always recommend folks use hardware recorders for screen capture you intend to edit.  They usually record to ProRes or DNx, which are much better for editing.

Thank you for the help guys, I'll use Handbrake for now and record in CBR separately from now on so I don't run into the problem again.

Not Constant Bit Rate.  Constant Frame Rate.

If it's a recording it should come out as a constant frame rate anyway as it's from OBS, I think just because it was a stream VOD the fps was all over the place

Some screen capture software records in variable frame rate to save space (I had one that did this) as when the image stops moving (like if you're on the desktop and the mouse stops moving) it actually just duplicates the frames.  Had a nightmare of a time even transcoding my footage.

Software screen capture often doesn't record a proper file for editing.  Hardware recorders are best.
