  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Some observations

Pretty nasty... mitch. I mean lets face it guys this thing is a great camera. You cant whip pan a film camera that fast, but I am glad other people are noticing this it just helps us all out as owners/ops/directors etc... I need to get a handheld example up for you guys both arms extended and shoulder. Shoulder you notice nothing unles your super long lens like 120 or so maybe longer. arms out our held to waist something like that you get the wobbles around 85mm. Lets not totally focus on the negative though. We are shooting cinema quality images at a fraction of the cost of what it was 2 years ago. Its amazing, just issues we have to be awear of.

Here is some rolling shutter on a whip pan.
Scarlet-X at 3K 48fps, 180 degree shutter and 250mm.

What lens were you using? If its a Canon IS lens and you have IS off you will see results similar to this.

As a side note when your shooting 1/48 shutter you typically stay away from whip pans as motion blur at this speed gets ugly. ( not talking about your example video)

That would explain it... The lens was a Canon EF 70-300mm f/4-5.6L IS USM.
Not sure if IS was on or not because I wasn't using the camera.

It was 1/96th shutter. Probably should say that I didn't shoot this footage. I let my friend borrow it for the weekend because I had no work and he wants to shoot surf videos.

I know theres a post by Joseph Hutson posted regarding IS on canon lenses with a video example of IS on and then off. I can't seem to find it.
You get a swaying effect from those lenses with IS off with movement.

Yeah I saw that the video was 48fps, I was just making a general note for everyone.
 
I think the only way to overcome the rolling shutter limitations of any CMOS chip is to go to a mechanical shutter, which is an option on both the Arri Alexa and the Sony F65. I have yet to see what that looks like, so I don't know how effective it is, but I expect it'll improve or even eliminate the problem. But that's a very expensive solution.

Nice explanation (with photo examples) on Wikipedia:

The stuff I've seen on Canon 5Ds and 7Ds is far, far worse than what I typically see on Red One's.

If that's the rolling shutter I have to put up with when mine arrives, I'm very happy :) That is quite good IMHO....especially at 250mm!!!

+1, I didn't think it was too bad either and how often will we be whipping that fast?
 
I'm still just very confused as to why the OP was trying to shoot the Scarlet handheld with an 85mm with the camera held "with arms stretched out in front"...seems like a disaster of a shot, unless you got some super biceps. I just cant get my head around what the OP was expecting from the shot...and why would you be so disappointed?

if you want usable "loose" movement in your shot at least get the camera on an easyrig or even a monopod with a head on it

He wasnt arms fully extended think more arms bent closer to his waist one hand cradling from under the other on side handle. It is still an unnatural way to film with a film camera but tends to be common as you get to smaller cameras etc... just doesnt work for this or DSLR's
