Question

60fps video mixed with 24fps video - help!

Hi all,

I know that this has been asked possibly many times before, but I simply cannot find a solution to this. I'm getting jerky-looking (or incorrectly playing) 60fps video on my project timeline...

I have a timeline with a mixture of 24fps clips and 60fps clips. Now, the 60fps clips are definitely recognised as being 60fps by Premiere (so it tells me in the clip properties) but when I go to "sequence" and click on "sequence settings" it's telling me the timebase is 24fps.

As a test I created a new project and just pulled in one of my 60fps files and I checked the "sequence settings" and it said the timebase was 60fps. It played perfectly and smoothly.

So something is not right in my project and I don't know what it is...the 60fps video are a bit jerky on the timeline so I don't know what is going on.

There must be a way to seemlessly use both 60fps and other frame rates in one project, but obviously I am doing something wrong.

Thank you in advance.

Al.

There is.  The 24 fps material will play back in real time, the 60 fps material needs to be Modified to play back at 24 fps so it's in slow motion.

Right click the 60 fps clips in the bin and select Modify>Interpret Footage... and set the frame rate to match the other footage.

    Hi Jim,

    Thank you for your reply.

    The 60fps footage is already in slow motion. It's as it should be. The video file is literally ready to go without any modification needed to make it look "right".

    I assumed, perhaps incorrectly, that Premiere would read its frame rate and simply adopt whatever settings it had.

    As I said above, if I create a new project and drag on a 60fps video on to the timeline, it plays as it should. But within my project, which has a mix of 60fps video and 25fps video it is causing the 60fps footage to look ever-so-slightly jerky (I can only compare the way it plays the 60fps footage as if the computer is processing a task and it's slowing down the video, but this is not the case).

    There is something that I've missed somewhere....a setting or an option. Either that or Adobe Premiere Pro is actually quite useless and can't handle different frame rates on the same timeline (which I'm beginning to think is the case!!!)

    Define "as it should".  Does that mean at 24 fps in slow motion, or at 60 fps in real time?

    One thing to note is that you should not mix ATSC and PAL.  The math just doesn't work out.  So are the other clips shot at 24 fps (ATSC) or 25 fps (PAL)?
