How do I fix a video that has jumping fps from 12fps to 30fps

Hello,

I have a problem with Vegas Pro 14, I got a video that has a properties of 12fps but in the middle of the video it will jump back to 30fps then return back to 12fps, so how do I make this video play like this on Vegas Pro? Because if I played it in Vegas Pro or after rendering it, it will play only at 12fps.

Also I have tried converting the video to 30fps but that didn't work too.

You mean you want to accelerate a part of your 12fps video source?

Yes, but if I played the video in my desktop it will play the part where it's faster on 30fps. On Vegas it will only stays at 12fps.

But I don't want to do this manually, like on each part I have to make the video clip faster.

Vegas Pro does not support variable frame rates.

Okay, so it's not possible to fix it?

In Vegas Pro, I doubt. Don't know if there's any NLE which would handle variable frame rates that way except the latest version 12.0.1 of Premiere Pro.

Hm. I did editing some VBR videos in Vegas Pro 13. It used to work (smart resample did its job, you should not disable it with VBR).

However, I did not like the result so then before editing in Vegas I converted VBR video into CBR in Handbrake. I did not mind some quality loss because of additional encoding (I just used high bitrate for the intermediate video).
