any advice about what to buy for Video?

Hi guys, I'd like to buy a new camera for video, Now I use Cannon 5d2 for video, It's ok, but I'm thinking about Slow mototion, the 5d3 noly have 50fps, if I want beautiful slow mothion, I think I need something around 80fps,(I know nothing about slow motion).


SO please advice is there any other Choice? 

What's your budget?

The 5DmkII will shoot 60fps, which is the standard for basically all cameras in the <$10,000 range. 

For high-fps cameras, look at the Phantom Miro or the RED Epic.

High-fps shooting is a very expensive thing to get into; you might consider renting a camera and light kit now and again instead of buying the gear.

60fps really is not much of a slow motion effect. Depending on what you're shooting your really need at least 120-240fps before things start to feel like slow motion. And depending on what you're shooting you would need even higher frame rates. People moving look pretty slow at 120-240, but things breaking or liquids really need a lot higher frame rate.

Probably the cheapest camera right now that lets you do quality slow motion (120-240fps) would be the Sony FS700. The Sony will do higher frame rates, but the quality goes down quite a bit.

I'm pretty sure that the 5DmkII does not shoot 60fps.

I'm sorry, you're absolutely right; almost every other Canon DSLR, including the $500 T2i, will shoot 60fps (at 720p), but the 5DmkII missed out on that and won't go this high. My mistake.

Does anyone actually have FS700 slow motion footage up on iStock? My understanding is that it will do 240fps into a ten-second-or-so buffer at 1920x1080 (higher frame rates are possible with a drop in resolution) but that bitrate takes a significant hit. There's also much speculation and test-chart-shooting by folks who insisit that even at 240fps there is a drop in resolution, but the camera upsamples it to 1080p.  Nonetheless, some of the 240fps and even 480fps stuff on Vimeo looks great in their "HD" resolution, so I'm sure plenty of buyers on iStock would be pleased with it... but would it get past the inspectors. 

I have some - essentially look at my newest files. I can't see anything dodgy doing on with the resolution - I'm very happy with the quality. 480fps is a different matter.

The quality at 240fps on the fs700 is pretty good. The camera is doing line skipping when you do slow motion, so there can be a moire problem on thin lines, but probably not as bad as the moire on a Canon 5DmkII.

I have 48 slow motion clips shot with the Sony fs700 accepted. And 1 rejected, but that was because I really cranked the saturation in post to try and get a dull looking ocean to look bright blue.

Good Work Forrestbro, I enjoyed your lightbox!

I know this has been brought up before but would that after effect plugin Twixtor be an option?

Not true frames so its not an option for iStock

thanks for the information guys, I like the slow motion effect of fs700, but if I buy fs700, how about the lense, is that ok to use my canoon lense? and how about the quality if I use cannon lense on Fs700.


Now I heard cannon 1d c is comming, not sure if it can shoot slow motion.


 

I have the FS700 since august,.. and very happy with it. Slow motion quality is very good up to 240fps in good light, like daylight outside.At 480fps, you will feel a difference in results, sometime edit a little and, or downsize to 720p will do, sometimes not.. If you are planning to do slo-mo in studio,.. be ready to use a lot of lighting gears in your set to succeed and always remember that shutter speed fasten dramatically when shooting high frame rates too.


For the Canon lenses, get the Metabone adaptor, that is able to control lenses from the camera.


Really like that cam,.. it has much more features than just slow motion too,.. I do not use much the 5D anymore.


 

Why not? Animations are also allowed.

Its a quality thing for video.

Twixtor works so well on some footage that I doubt anyone would notice. Is Twixtor officially forbidden on iStock? Or any form of time remapping?

Yep - that's the official stance - in camera overcranking only.
