Strobing on slow pans 7D
Hi All,
Been shooting with my 7d for a month now, really like it, have come from Digi so there is a fair bit to get used to!
My only real issue thus far is that I am getting awful strobing when panning on a tripod. Doesn’t matter what speed, or where I am on the lens (though at the end is worse). Looks fine when shoot it (as far as I can tell at least), when it gets dig’d in the strobing is there!
I’m shooting 25p @ 1/50 – Then going to Pro Res for progressive. But the native files have the strobe on them too…
Oddly, the whip-pan issues I keep hearing about are negligible (hand held stuff doesn’t seem to suffer from it),I just can’t seem to get a nice slow pan without awful strobing…
I’ve got fast cards and it’s freezing cold here, so it’s not those things (I have heard them sited as potential issues..)
Establishers are rubbish without a bit of a move on them, what can I do??

I noticed this on a few shots, most of my footage is fine. I’ll have to do some tests to see how to eliminate the strobing during a pan.

That camera makes p50, doesn’t she?

What most people refer to as strobing is caused by an inconsistency between the camera’s frame rate and the flicker pattern of the lights used.
If that’s what you are talking about, then questions to ask are: What if any lights are you using? Are you in the right part of the world to be shooting 25p? Or is this a different problem altogether?

Where are you viewing the ProRes files, in FCP on broadcast monitor, or in Quicktime?

Cool, thanks Malcom

It can shoot 50p, yes but I prefer to shoot 24 or 25 unless I specifically want slow mo stuff…

I’m based in the UK, so yes, 25p is the norm here. All of the shooting I have been doing is outside so lights have not been a factor.

All three!

Hi Phil,
I’ve put 3 clips up

They are entitled rolling shutter tests 1, 2 & 3
It’s worth mentioning here too that I’ve been using a vision 10, so the head is smooth as you like, though these clips may make it look like that is not the case, hence my problem!
