Slow mo clarification please

[Jonathan12uiz]

Ok so for all my slow mo clips I try to make it easy.

To my understanding, the easiest way to do slow mo is only in 720p60 with 1/125th shutter speed. Then 50% the clip in editor with no frame blending.

That is all fine and dandy I guess, but how would I do a 1080p24 slow mo?

I thought I read about a guy with a 5d that shot in 1080p24 at 1/4000 shutter and got some great super slow mo, but how did he do that? 50% speed? Slower? Frame blending?

I just want to know how many other ways besides the 720p60 50% there are to slow mo with the gh1

1080p24 is about the worst possible starting point for slow motion footage. There will be blended frames, severe ghosting, and/or duplicated frames - Unless you use something like Twixtor which creates new frames through motion estimation.

I always shoot 50p or use my FX7 and shoot 1080i if i think there is any chance I will want to use slow motion.

With the camera being locked to only a couple of frame rates all you can do besides those set ones is work with it in post. Which isn't going to be as clean as if you could do it in camera. So for the NTSC version you're locked at 60 fps which can give you a decent 1:3 slow mo in post if you are putting it into a 24fps timeline. It's no Phantom but that's pretty good. That's on par with several 16mm cameras.

i did my first long track of bball players on the bench last week in 1080 and it looked terrible even at normal speed. mind you i was shooting at 1/50th so that didnt help. There was no chance to do a reshoot and I had to have it slowed down for the effect I wanted. Had not planned for it to be slow mo originally and was a post decision. Twixtor managed to save my footage to a usable degree but warped out the ball bouncing across the floor but it was looking heaps better that original. thats how ugly the original footage was.

I will never shoot in 1080 for slow mo again, especially if there is alot of movement.
