7D HELP: Flickering Buildings and on the Water

Sounds like a recipe for some really disappointing footage, actually. Wide-angle deep-focus shots are the ones that DSLRs struggle the most with, and the 720p mode on the Canons is really bad -- it's quite low-res and extremely prone to aliasing. Combine that with the wide-angle and deep-focus and the rolling shutter, and I would suggest you really should be looking at just about any camera other than a Canon DSLR for your helicopter shots.

Sorry Barry, But I have to disagree.

Those ariel shots were done with a T2i. This video looks amazing!

Hi EVEYONE!

As Thread Owner I am really happy to be able to discuss with you ALL my situation, questions and problems!!!!

I have 3 Weeks Time and then I will be in the middle of the shooting..

Well, I can find here Tipps, Different opinions, and example Shots. I think that I should take the best solution for my point of view.

Well, something that I have to accept: My 7D will also show some Aliasing in 1080 Mode. Bad side: 25fps and Slow Motion not really possible. If I shoot at 720p->Slow Motion possible but Aliasing / Moire.

So between Slow Motion and Moire->I would stay at 1080 (Better Footage and NO Slow Motion)

One thing is sure: I will use my 7D in 1080 Mode for all Shots (On the Yacht, Close Ups, etc..). Reason: I have my Filters, Rigs, etc..

For the critical Scene like my post and on the helicopter following the Yacht I am planing to do that:

I will shoot with 2 cams. The 7D and the Sony HDR-XR500 at the same time (My old HD Cam). The sony cam is very small and I will fix it on my Rig. I can choose the best shot than.

What you think about that?
 
Oh another question: If I shot in 1080 at 25 FPS. Which Shutter Speed would you take for the shots on the helicopter and following the Yacht in the sea?

And they use a dampening system. You can shoot with a DSLR on a heli (remote or manned) but if you don't have the correct system in place and are trying to hand hold it or direct mount, you are going to get rolling shutter problems. I've seen it. My cousin is a Blackhawk pilot and I know what they've produced in air. Most of the helicopter systems I've read about use a gyro mount. Using one, they produce amazing footage.
 
FWIW:

ariel is the lead character in the little mermaid
aerial is the word for things related to heights

The car video is showing some rolling shutter though in a few of the shots. I didn't see much Aliasing. They used some post video stabilization which gave it a little "wobble".
I've seen tons of footage shot at 1080 with the Canons. Im no Canon user so I cant comment on the moire at 1080 vs. 720.
This was also pretty far away from the ocean, so you cant see wave details... which probably helped with the moire.
Best approach would be to be safe, research effect Heli companies and/or see how the footage looks form these high end Heli companies and the camera they used.
Also, the clips played to long showed loads of problems, so short intercuts will help.

I agree, I mean I'm not saying the shots look perfect but used in 5-10 second cuts it works. Also what would be a good gyro system to use for a Dslr?

Sorry to hi jack this thread, but I have a personal project where I might go up in and shoot something in a Helicopter and want to find the best affordable way to do it.
 
I've solved this problem by adjusting the focus on the lens very, very carefully so that my focus is off – then sharpen in post.

This technique is not for everyone or every situation. Also it helps to run tests as you want the minimum amount of off focus to stop the moire/alias.
 
Hi Guys,

a friend that are over 30 years in the business prepared this mount for the heli:
Steadi_Mount.jpg

Please tell me your opinion for the heli shots on the cost (like my post) and following the yacht in the middle of the sea:

- My lens has Image Stabilization, so it should help a little bit and we will shoot so wide we can
- 1080, 25fps, Shutter 50? or maybe higher?
- Pol Filter, but no ND Filter (because it could be difficult to adjust the focus than)?
- Set the Sharpness to Zero? And bring it back in post?
 
I can't really comment on your mount but if you want proper shots from a helicopter, then use a gimbal mount. Anything else and you're wasting your helicopter hire time. Your shutter should be at 50 if you're shooting 25fps. If it's a sunny day, you'll likely need nd filters - they don't make it any harder to focus. As for sharpness, do a forum search on picture styles.
