Just curious how to make sure music stays in sync with shooting 48 fps playing music at exactly 2x the speed?
Does this work shooting 23.98 time base?

Would love to know the tricks of this using the EPIC

thank you!
 
How did you do your music playback? What speed?
 
So just to confirm (I will test) i can't shoot a 23.98 timebase, I need to shoot 24 timebase and shoot at 48, and play music at 2x?

BTW, very nice video!
 
I would expect a TB of 23.98 to drift @48fps. So long as your frame rate is a multiple of your time base I should think you could shoot in whatever time base you choose. Right? 1 second= 1 second, 23.98 frames does not =48/2

Let us know what you learn.

Very true! So I guess shooting 47.96 would solve that.. I keep forgetting how easy it into enter any frame rate you want
 
Where will this be required to play back Justin? Be sure to choose a time base that the player can handle.

Ahhhhh, yes, true.. Guess testing will be the best thing.. Are there any APPS that you can doctor up speed on music or song playback?
 
Frame rate..

Frame rate..

Be sure to test playback at 48.048, and actual 48.00

Call Glen Trew at Trew audio for the definitive expert opinion... he has prepared more playback than anyone else I can think of in the USA..
 
We shot this video last year using a mixture of 12fps, 23.98, and 48fps, so we could mix high speed, slow mo and a "normal" timebase.

I did a basic 2x speed up on the music track for the 48fps, but I didn't feel like it mattered that the math be exact. I think the audience forgives a little slip, as it's being slowed. However, I did make sure to give the band the 2x sped up track a week in advance so they could practice. I felt like this was extremely important. And it certainly made a difference when we were shooting, as they were prepared for how much faster they would need to perform and sing.

Hope this helps...
