Question

Audio lags two frames behind video ONLY in Premiere

I recently discovered that any video I bring into premiere is two frames out of sync with the video leading the audio. I have tested and confirmed this using Catchin' Sync: http://quietart.co.nz/catchinsync/

VLC is in sync. Quicktime is in sync. It's just Premiere, and it's ONLY during playback. I can scrub through the timeline at low speed and everything lines up correctly, but as soon as I play something back in real time, it slips.

All the audio waveforms line up as they should. When I scrub through the timeline, everything seems fine and in sync. But when I hit play, the audio lags ever so slightly.

Anyone have any thoughts on what could be causing this or how I can fix this?

May we have more info to go on? System info and media specs would be great, @zstoltz and @SteiSi-Post_02.

Thanks,

Does your sequence frame rate match the media frame rate?

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

Free programs to get file information for PC/Mac http://mediaarea.net/en/MediaInfo/Download

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

.

Does your video use a VARIABLE Frame Rate? See https://forums.adobe.com/thread/1110005

If yes, use https://handbrake.fr/ open source transcoder/converter to convert to Constant Frame Rate

I'm on Mac.

It's not a VFR issue. I've already checked that.

I've attached MediaInfo screen shots of just one example of the type of video I'm sticking in Premiere.

The sync issue I'm experiencing doesn't seem to be a problem for other people I'm working with on the same project who are running Premiere. At least not the ones who are doing sound (thank goodness).

I've done a lot of research and can't find anything like what I'm experiencing, which leads me to believe that there's some issue with how my computer is interacting with Premiere, but I'm hoping there's a simple fix or something I can check. It's odd because the problem is the opposite of what there are options to fix in Premiere (I can delay audio, but I've found no options to delay video).

How are you monitoring the video?

How are you monitoring the audio?

What is your audio hardware configuration?

What are your Playback preferences set to?

Are you using Mercury Transmit?
