How can I edit and export 48fps footage in Premiere CS4

What program is that screen shot from? I have no trouble making H.264s (ether in Quicktime or an MP4) in any frame rate in AE CS6…

AE, but I only have cs4 🙁

The project is a comparison between motion blur at different framerates. It’s somewhat of a scientific endeavor more than a movie. It has to be exactly 48fps or the experiment is void. I want to be able to view the programs on a computer, and it will eventually be projected. I don’t have the details about the projector, but I’m assured it takes h.264 quicktime files at any fps.

Ah, well, then that isn’t going to work. I did preface my original post by mentioning I was working in CS6.

CS6 can make H.264s in any frame rate you want… To test it I made one just now at 46.98fps, not standard in the slightest.

You can still edit this project with your current software, (though I have no way to test if Premiere CS4 will edit 48fps, you might have to do it all in AE or in Premiere at 24fps) and then download the trial of CS6 to do the render. Not that I like the idea of using a trial version for a paying project, but in this case if you can’t afford to upgrade you’re kinda stuck with using the trial.

ok now i understand what youre doing
you should be able to test it to a broadcast monitor IF your hardware supports it, and i dont know of any that does currently

i also dont believe that h264 supports 48fps

like i mentioned earlier, i tried rendering a few different formats at 48fps and they all got really confused when i tried to play them back

.wmv was actually pretty funny .. it kept skipping forward every 10 frames or so ^.^

howd you do that ?

i was trying to do it earlier and it locked me into standard frame rates

Um… I added the comp to the render queue, clicked on the output module and changed the codec to H.264, render and done. This is on a Mac, perhaps that makes a diference.

In the output module settings there isn’t actually anything that sets the frame rate at all, it’s set in the render settings.

hrmm weird
im on a pc and it only had standard framerates as my options ..
ill have to test this mac business 🙂

Don’t forget I’m on CS6.
Tested on a PC. The options are exactly the same.

im on CS6 v6.03
when i change the format to H264 i get the following message
“Settings Mismatch”
“Warning: Frame rate of output file will be adjusted from 48 to 50 fps to meet format constraints. Audio may not synchronize.”

HOWEVER.
Rendering as a Quicktime H264 allows rendering to 48fps!

Now we know 🙂 … i learned something too.. its a good day 🙂

edit: playback sucks under windows media, but quicktime played it back perfectly.
