Have you guys done any slow motion video with the 5D2? the highest frame rate I can get with this camera is 30fps, the 550D, 60D, and 7D can pull 60fps at 720p...what is up with Canon capping our 5D2 at 30fps? LOL


Here is my first attempt taken with 85L II @f/1.2 and 1/90s, ISO 800; 1920x1080 @30fps. Can it be improve if I did it outdoor with much higher shutter speed like 1/500~1/1000s? :)

Given how much bigger the FF sensor is, perhaps the maximum frame rate is limited by how quickly all the data can be processed.


At the beginning of time there was absolutely nothing. And then it exploded! Terry Pratchett

I don't believe that comes into play.

1080p HD video resolution coming off the sensor of the 7D and off the 5D II is the same.

1080p Resolution = 1920 X 1080

Why dose the 5D II only do 30 fps, while the others does 60 fps?

Because the 5D II is the older model, and doing 60fps @ 720p wasn't considered an option during design.

When you are talking about data being processed keep this in mind.

Canon states in its manual for the 7D that you need a FASTER CF Card when doing 8 fps STILLS. For Video you can used a slower CF card.

Why? Because of the amount of image data being processed for the mode resolution.

8fps Still - 5616 x 3744
1080p HD - 1920 x 1080


I guess, when it comes to doing video today, the Canon 5D II is a dinosaur! :lol:

Well Ben, I think your attempt at slow mo came out quite well since you lack the 60 FPS. I have to dabble into that realm, care to share what software you used? I'm very interested.

Looks like you used Timewarp in After Effects, it looks nice and smooth :) Just go with max details in Timewarp, a lot better than regular frame blending.

I use Twixtor plugin for After Effects, it's also available for many other popular video editing software. You can youtube twixtor tutorial (by AcrezHD) and i have learned to use it in about 15 minutes. :grin: As long as the subject has no massive motion blur I think slow motion would work quite well in Twixtor with only 30fps.

Slow motion video with 5D2 - no :-)
Slow motion need more fps, I would say. Ok, I had the luck to work with 1000 fps Visario camera, worth USD 100.000 some years ago.
