I have a bunch of recorded files that are either in a .mp4 or a .ts file that I've been recording to use for the past few months. All of them were recorded with Avermedia's Live Gamer HD.

For the .mp4 files, I can view them back perfectly in sync in Media Player Classic, Quicktime, and Windows Media Player, but when I import them into Premiere Pro CS6 they drift out of sync. I found out that this format from the packaged recording software (RECentral) provides a variable framerate. I'll post the mediainfo information from one of the files if anyone wants to look at it. I then went back to using Sony Vegas 12 to edit the videos because the audio did not drift out of sync like it had in Premiere. My problem here was that even though the audio did not drift out of sync, I could not sync a separate audio file of my voice to the video because it has a variable frame rate.

After not solving those problems, I moved onto using the .ts files. For whatever reason using the same recording software this file output gives a constant frame rate. Because of that I'm able to edit these in Premiere.

Then I encountered another problem. Even though I can edit this format more easily in Premiere, it freezes when loading or drastically increases memory usage to the point where I can't do anything on my computer (I think that may be because the file sizes are decently large thought). So I then tried to import these into Sony Vegas to find out that it only gives me a video track, not noticing the audio.

What annoys me more than the problems that I have, is that at the end of January I was able to edit and .mp4 file perfectly in Premiere. Since then though I've had to reformat my hard drive to install new parts into my computer.

So in short I guess my questions come down to is there a way to fix the variable framerate without any quality loss in the .mp4 files. And is there a way I can make Sony Vegas read the audio in the .ts files or fix the loading issues in Premiere?

I greatly appreciate any help!

I upgraded to Premiere CC and it seems to have fixed my problem with crashing trying to load .ts files. I'm still looking for a way to fix the frame rate issue with the .mp4 files though.

Audio film rate of .mp4 files out of sync when importing to Premiere Pro CS6?
Or, CS5.

I use Premiere Pro CC and may be able to offer some assistance. Do you use a separate drive for your source files or are the files stored on the same drive as Premiere and the OS? Though this won't help with the sync problem you may want to consider upgrading to 16GB of RAM as it will definitely help with large files. I will be looking into the variable frame rate issue.

I record the files onto a separate SSD drive and then transfer them to an external drive to store them. So when I load them into Premiere it's from the external drive and Premiere is on the same drive as my OS. I do plan on upgrading to 16GB but I have to wait a little while before I can.


I've also looked at some of the links above from my searching before he posted them and none have been able to help so far.

Is the external drive a USB 2.0, USB 3.0 or eSATA drive? Just wondering how that might affect the process as it relates to transfer speed. Anyway, I know that doesn't help with the variable frame rates. However, it might have an impact when trying to edit the .TS files in Premiere. Do you get the same freezing problem in Premiere if you import the files from the SSD instead of an external drive? I'm thinking the external drive could be causing a bottleneck but I could be wrong.

It's through a USB 2.0 cable, I haven't tried loading them from the SSD of my main drive just because of space. I can deal with the longer load times on the .ts files because they do work after they load. Right now I'm mainly trying to find a way to either fix the variable frame rate without any loss in quality or a way to sync the audio.

I spent a while researching the issue of working with a variable frame rate clip and I couldn't find a suitable solution. I'm not saying one doesn't exist but from what I read it appears to a difficult task at best.
The links below may be helpful with syncing audio in Premiere Pro CC.
