Wich one would you go for (if you were shooting a slowmotion video)?

[DullElysium]

So let's pretend you have to shoot a slowmotion video with let's say a Canon eos 550d.

You'll be shooting everything else with 24fps 1920x1080.

Would you shoot the slowmotions with the same settings and the just slow it down to 50% OR shoot the slowmotions with 50fps 1280x720 and then slow it down to meet the 24 fps. The later version would mean that you had to stretch the video to the same resolution as the rest of the video..

I was just wondering wich one is better. 24 fps would have better resolution but 50fps would have smoother slowmotion.

I'm not personally shooting anything for real. But I was just wondering.

I'd always choose the higher frame rate if you're slowing stuff down.

Why not shoot at 1280 in both 24 and 50fps?

 

[DullElysium]

Yeah I was wondering if shooting everything 50fps and then converting the normal stuff to 24fps later would be better. I remember readin somewhere that converting higher framerates to 24 isn't the same as shooting with 24fps from the start. Any truth to this?

It'd just be cool to use the full resolution just because there is an option for it.

Edit: oh yeah. If i remember correctly there isn't an option to shoot 24fps 1280.

It's actually how they really do it...they never film just at 1080.

So what you're saying is people shoot the normal speed stuff with 1080 and the slomos with 1280 and then just stretch it to dit the screen? Will these shots be significantly different quality wise?

I would just shoot it all lower res at 50fps. Do you need the higher resolution?
For slomo, the more frames the better.

Here's a slomo trick:

No, I was referring to higher res all the time. You should figure out how long the scene is and figure out the math and how many fps you're bring it down to. You can do 60fps and cut it down to 30fps.

You mean lower res i guess?

But yeah. That seems like a solid option. And since it's 50fps it'd mean slowing it down to 48% would give me 24fps.

Do you think downgrading from 50fps to 24fps is similiar looking than actually shooting at 24fps? This would go for the normal speed stuff.


Edit: my bad. I've been saying 1280 instead of 720. So i see where you got the higher res.
