Canon to add manual video controls to EOS-5D Mark II
Date posted: Tuesday, May 26, 2009


Due to high demand, Canon will soon release a firmware update that will allow users to adjust the aperture, shutter speed, and ISO while recording videos. I know a lot of folks wanted this, and it's nice to know that Canon listened. A little more detail after the break


Thats nice but hum what exactly does that mean for recording video ?

Are you gonna be able to change your aperture/ss/iso while filming?

Was it only me that was expecting to pick whatever aperture/iso i wanted to record my movie in the first place? SS might be weird, even at 1/4000th, its still only gonna be 30fps no?

Somneone with a 5dm2 please chime in here...

i'm pretty excited about this!!! up until now i've had to trick my camera into using a large aperture by holding my hand over the lens til it opens up..then take my hand off, let it adjust and push exposure lock before it closes the aperture.

as far as shutter speeds go, someone can correct me here, but the only thing i can think of is it does 30fps but each frame is its own picture using whatever shutter speed you have...so a fast one will have less motion blur with moving subjects when you pause on that certain frame. also less motion blur when panning??? i'm just guessing here.

edit....yea, it's the same as still pictures. you stop motion with faster shutter speeds.
you can see a comparison on this page

Holy crap! Good bye 40D, hello 5DMKII and loads of debt!!!

Definitely makes the video feature (much) more useable... I'm still holding out for 24p though. ;)

[TheObiJuan]

My Sony TV can automatically convert it to 24p. :)
Can the conversion not be done in post?

I haven't tried it, but my understanding is it is a mess going from 30p>24p. You can go the other way no problem. And supposedly, even 60i>24p is doable. But 30p>24p is to be avoided if possible.

[adam75south]

peter can you give me a cliff notes on why 24p is better than 30p? i understand broadcast television is 24p, but i'm still pretty lost on that stuff. does it make any difference at all with youtube hd?

Well it's purely aesthetics/personal preference. There's no technical advantage at all. To me, when you have those extra six frames per second (30p/60i), you get video. People will argue forever that it's more than 24 fps that gives film it's "look" - lighting, DOF, contrast, etc. But doing all those things will never make video look like film (again, to me.) Even soap operas have caught on. For years they have very dramatic lighting, long lenses (for some shots at least), etc. But they were all shot on video. Now at least one (Days of Our Lives or All My Children - don't recall which) is shot with Canon XH-A1's using 24f (rough equivalent of 24p on that camera.)

But again, we're talking purely personal preference here. Technically - even on YouTube - there's no advantage one way or another.

I think it is an interpolation type thing that gets people upset. I expect most of us that consider ourselves still photogs that just do video for fun won't care or notice much. But it seems like in addition to the "film look" there might be an issue with how it is displayed on the TV. Just like when you drop the resolution on a photo, what pixels get lost, when you drop those 6 frames, which ones do you get rid of? Is it going to look almost jerky to have 6 longer gaps between frames each second?

Well there is a difference between spacial resolution (dropping pixels when resizing a still image) and temporal resolution (dropping video frames), but yes, you hit the issue exactly: dropping 6 frames from a 30 fps video sequence will never look normal/smooth compared to properly recording 24 fps in the first place. My Canon HV20 records 24p in a 60i "wrapper" - it basically repeats 6 frames every second which are appropriately spaced out in the 30 frame / 60 field sequence, which can be plucked out later by the right software (Canon infamously declined to "flag" those extra frames which would have made deriving pure 24p much easier but there's still software that can figure out which are the repetitive frames. Interesting the new HV40 does pure 24p - no 60i wrapper - solving that problem.) But you are right that 6 frames plucked out a 30 fps sequence - even if evenly spaced - will cause an ugly result.

[adam75south]

ok so why does it need to be at 24fps? why drop frames at all?

[TheObiJuan]

I like the view, the feel, that 24p gives; cinema type look.

x2 i prefer it aswell

It's quite nice to finally be able to set the shutter speed and aperture in manual live view mode when taking shots. :)

The DoF control with this new firmware will make the camera a lot more useable.

I love subject isolation, but shooting everything wide-open is not without problems.

[VTEC_EATER]

Does anyone have examples of 24 fps vs 30 fps? I cant really imagine what what you guys are talking about. Is it similar to a 60 Hz television vs 120 Hz?

[adam75south]

yea same here. i tried to find some on vimeo but couldn't tell a difference. it's probably the same as the difference between real bokeh and photoshop blur...comes with experience.

[TheObiJuan]

Watch Lost (24fps) then watch Survivor (30fps).
The movement and 'look' is completely different.

I'm totally hooked on Lost, sad but true. ;)
