Audio and Video are not Synced

[RoboticREX]

I record gaming videos for my youtube channel. lately, I upgraded from a free software to Adobe Premiere Elements 15. Sadly I have not been impressed yet as all my videos audio is of synched when I import them. They are fine before import but after it gets more and more of sync as the video progresses. I NEED HELP. I left all my recording and video specs below. What settings should I use?

SPECS:

Video Format:

MP4

Size: 100%x100%

120 FPS

Codec: H264 (NVIDIA® NVENC)

Quality: 100

AudioFormat:

Codec: AAC

Bitrate: 192 kbps

Channels: stereo

Frequency: 48000 Hz

Any help ASAP will be greatly appreciated

Thanks!

Premier Elements is a video editor designed around cameras that shoot in a constant frame rate.  Video capture devices and software seem to use variable frame rates.  I don't know why, but it will cause sync problems.  

To fix it, you can run your captured video through something like Handbrake and convert the variable frame rate to a fixed frame rate.  Others have done this and been successful.

I don't know which of the half dozen "affordable" video editors are ideal for captured, variable frame rate footage.  If you find one, I would be interested to know.

Bill is absolutely right. FRAPS and other software used to record videos on your computer nearly always produce video with a variable frame rate -- which results in out of sync issues when you load it into a video editor.

Okay, thanks!

Handbrake works great, Thanks man!

[Bill Sprague]

That's great!  Can you mark my answer "correct".  I get points and, at my current rate, I might get free software in a decade or so!

[RoboticREX]

Yup!

Great. Thanks, I will let you know how Handbrake works out.
