Here's a problem that's hurting my brain..

I have an old video that was rendered at 25fps..

I'd like to now replace the 25fps video with new HD footage.. but the HD footage is 60fps,

and the old audio was (meticulously) synced to the 25fps footage and doesn't match up with the 60fps footage..

Between the old video, the new video, and the sequence frame rate, is there some way I can get these things to match up? thnx!

One thing I've noticed is that PP isn't especially good at mixing PAL and ATSC frame rates.

Using 25 or 50 in the same project, you're good.

Using 24, 30 or 60 in the same project, you're good.

Mixing the first group with the second, not so much.

That is so true.

I try to avoid ntsc footage at all cost as I am living in a pal-country.

If I have ntsc footage I need in a pal project I convert it first in Ae.

Interesting question. Sort of scratching my head. Because if you have 1 second of audio with 60fps video and 1 second of audio with 25fps video the length of the audio should always be 1 second. The difference is you are just capturing more video frames per second during the duration of the audio. So I would think that the audio and video should line.

Why 60fps and not 50fps? 50fps would be the logical way to go because now you are mixing standards.

Are the sample rates of your audio different?

Does the audio start in sync and then drift apart?

What are the camera and audio devices used for capture?

The sample rates are the same, but the video doesn't align.. it's actually quite a mess.. it may be a lost cause lol.. the original source is a rip of a rip of a dvd, and the new footage is a screen recording of a dvd clip,, so i may have to sync frame by frame :$

Hello again! So, I got a copy of the DVD, copied the VIDEO_TS folder to the hard drive, and tried playing the .vob files in Quicktime and VLC and they looked very glitchy (see images). When I tried importing the .vob files into Premiere, it would only import the audio component.. Any ideas? thnx!

Also, I tried ripping the scene from the DVD using HandBrake on a number of different settings, and the resulting video was consistently less detailed and played less smoothly than the source (i tried taking a comparison picture but Apple censored it)..
