Flicker in t2i video?

Hi guys, I'm wondering if anyone has had this happen with their t2i video.

It's happened to me a couple of times. The light will change/flicker, almost as if the aperture or exposure correction was shifting during video recording. Any thoughts on this?

You can see it happen in this clip at :07 and again at :10

I tried to disable the exposure control and have since disabled the auto lighting adjuster but want to get to the bottom of it.

thanks in advance!
 
The only thing I can think of is the white balance is set to auto. Something similar happened to me when mine was in auto. Maybe its that?

Seems like your white balance is set to auto and by you going closer to your subject the camera compensated for the difference in lighting. Other than that it is BARELY noticeable and not something IMO you should stress as had to watch it twice to even notice it



peace
 
Does it do the same thing in the raw footage? Thats happened to me before but the grading plugin was the problem not the actual footage
 
hey guys, thanks for responding.

ghking, looks like you're right. original footage looks clean, or if there's something there, i don't see it. phew, i know it's not too terribly noticeable but it was enough to bug me.

thanks again for your time dudes.
 
my T2i does the same thing. I will do a test shoot tomorrow and see if it's the auto white balance.
No more than the camera costs, what it does in terms of shooting video is okay, but man if the 7D or Mark 5 is the same I can't see using it professionally as opposed to a pro video camera just to get the shallow DOF. I also have an HVX200 and Letus Lens adaptor kit I've shot with and will continue to use for long shoots. Even though it's a longer setup time, it gives better DOF control and of course pro audio inputs and other nice features. All the better light sensitivity and less noise that's raved about with these cameras..i just don't see it's that much of an improvement for all the tradeoffs you end up making. But like I said, for the money..and if that's all you have..it's great. As far as a still camera...it's the best ever! I love it.

You obviously do not know how to use the Canon t2i or any other dslr, so before you go out and say that it is not this or that you need to spend more time with your gear as it is only a tool. Outside of long recording times there is nothing your Hvx can do that a DSLR can't without the proper gear.


Also your HVX will never have the low light sensitivity that a dslr has. To finally top it off the Hvx cost about $4000 with that kind of money you can have a dslr with an amazing kit, lens + more and probably still have money left over for another camera.

Well that's a little shortsighted and not true at all.

I love shooting with my 7D, but there are plenty of circumstances where I'd want an HVX or my old Ex1 back.

I agree that in the post you were responding to it seems like he needs to get more experience with the camera before coming to a conclusion. But instead of your kneejerk defense of DSLRs, I think it would be more productive to offer advice on how he can get better footage from his DSLR.

I have an HPX-500 and a 7D. Both are great cameras and serve the user's well. I believe there is no need in saying one is better than the other. It is impossible to compare the two cameras as they are completely different animals. Just enjoy them for what they are. We are so lucky to be living in these times when manufactures are offering so many great options.

I was waiting for a hostile reply. There it is, thanks Cieloent!
But where did I say it was NOT this or That? I only stated my opinion, hoping to get some OTHER OPINIONS. Ok let me say this then: The Canon T2i will NOT record professional, usable audio. But I already knew that before buying the thing. The camera does NOT have any audio controls or settings in the menu. The camera will NOT output to a monitor live video in HD while shooting. The camera will NOT allow you to see what you're shooting outdoors in bright light because you can only utilize the LCD screen (unless you buy an adaptor). The DSLR has a CMOS sensor and nasty jello motion. And oh yes, in auto white balance the camera flickers under changing light levels.

Yeah the camera costs thousands less than my HVX. What I guess I should have clarified in saying was that since I ALREADY own an HVX and already own a Letus DOF adaptor, I just couldn't see the benefits of switching to a DSLR. And as far as my statment about better (more shallow) DOF, that is a FACT. The T2i's sensor is slightly smaller than a 35mm camera frame. With the Letus adaptor, I get the same DOF as a 35mm camera.
Anyway Both have pros and cons. I totally agree. The HVX has more noise in the picture. Supposedly the DSLR's are better light sensitivity. Not saying thay don't. But right now for me, the Cons of the Canon DSLR outweigh the pros. Unless someone can show me how to overcome these issues without throwing alot of money at it.

I hope most of the issues with DSLR shooting video will be addressed/solved in the Panasonic AF 100 4/3 camera coming out at end of year. So rather than spending thousands on a DSLR to try and make it do what it wasn't designed to do, I will wait and see about the AF 100. Of course we are talking a small investment here. But to spend more on my DSLR to make it work the way I want seems like a waste for my budget. Rather wait til I can afford something that will do more of what I want it to.

Now, after all that to try and make my points clearer. I will say this. There is some really awesome video on here that others have shot with these cameras. And given the time, I will spend more time with mine and try to get better footage. But when it comes to shooting stuff for clients for my business (to earn a living) I won't trust or deal with the headaches of a DSLR until either I get better with them or they improve upon them.

Last thought: If I got on here and said a piece of equipment sucked or was not this or that, WHY in the world would someone get defensive or offended by that? I find it so amusing how people get all torqued up on DVXUSER when another person disagrees with them about a piece of metal (or plastic) that is here today and thrown in the trash tomorrow. LMAO
