Does this video look right?

[Texas_Willie]

I am wondering if I have things set up correctly for 4k video, with my new 8.25 Peau lens set up. I watched it this morning and it seems to jerky...I don't know if it is the video or my computer.

Feedback would be appreciated!

TIA

Well it was a little windy and coupled with the narrower view there was some shake apparent in the video, better in some spots worse in others. Overall the picture looks pretty clean though. Did you have any lenses or filters on the camera? I was developing a sunshade for the CG03+ a while back and in the end found the gimbal, while very good, cannot handle much overload. There is another video on the forum where a camera is being flipped sideways 45 degrees in a stiff wind. But ultimately the narrower view is magnifying subtle movements that would normally not be apparent. I think that lens has a 41 degree field of view vs the typical 95 degree.

Nope i see it, I edited my post when you edited yours now it is there.

Ok, so you are seeing the same thing I was...I guess my next question is what settings should I be using for 4K video to get rid of the shakes? I don't think the wind was strong enough to make that much difference...It was only about 5 mph and I have done videos that were silky smooth in much higher winds, although those were with the stock CGO 3+

Do you know what your settings were when shooting? With that narrow of a view, when shooting video you will want to get the shutter speed way down to twice that of frame rate so if you're shooting 30FPS then you'll want the shutter at 1/60th and to do that you will need ND filters

I shot the video with default settings..I do have ND filters and was using an ND8 from NEEWER. Next time I will make the adjustments to the frame rate and exposure and see how that works. Thanks for the feedback Ty

Its like shooting a rifle. Small movements will have a bigger effect the further away the target is. With a camera as you zoom in, the movements of the camera become very critical. That type of lens will be great for Photos but as you see, videos will be a little more difficult but as I mentioned above to get the best picture drop that shutter speed.

TW, I found on a bright and sunny day that an ND 16 was about perfect to get the exposure right with a shutter speed of 60.

P.S. What a beautiful place to fly, I would love to be able to shoot in an area with mountains.

Thanks again for the input Ty...Much Appreciated. The Pacific Northwest is indeed a photographers Paradise!

You're welcome, anytime. Look forward to more videos.

I watched the video several times and there seems to be slight instability throughout. I'm rather new here and am always impressed with how stable the video generally is. Is it possible that somehow the camera is connected directly to the H? It seems that the dampers aren't doing their job.

There are at least 3 members on the board (including myself) who have obtained the same results from the Peau 8.25mm. Unfortunately the CGO3+ gimbal is being pushed to it's design limits. I found the image quality to be fine for short "B roll" sequences, but there is little you can do to significantly remove those shakes from video output.

Much of the marketing of the Peau lens has been as an inspection and construction areas, when used for photographic inspections. When taking photos, the ND filters need not be used... the resultant high shutter speeds will minimize any softness in the image.

Because the dampeners are designed to accommodate a much wider angle lens. Changing out to a longer focal length lens increases the magnification, which is what makes the vibration visually perceptible.

After I posted my first reply here I hadn't considered any electronic stabilization and wondered if recording at 1920x1080 might render different results. Do you know if any type of stabilization is used by the CGO3+? Your reference to high shutter speeds minimizing image softness is confusing to me. Can you elaborate on that? There are just so many things that leave me baffled. I'm still amazed at the H and it's capabilities. Hardly a day goes by without me learning of additional features.

To my knowledge there is no stabilization used in Yuneec cameras... I have used the stabilization program offered by Mercalli

Mercalli V4 SAL

I do not know that recording at 1920x1080 would help, as that basically further crops the 4K area to HD.

As far as my reference to high shutter speeds... the following only applies when you are using the camera for photographs, not video. Settings for optimal photos are not the same settings for optimal video. The shakiness that is apparent in the video is caused by a slight amount of movement between the camera and the subject.

In a still photo the same shakiness will make the photo appear blurry at slow shutter speeds... (for example the video shutter speed of 1/60 that TyPilot mentions above). However not using ND filters when shooting photos, produces high shutter speeds of 1/1000 or 1/2000... shutter speeds in this range will completely eliminate that blur by reducing that exposure timeframe and "freezing" the image.

I shot this footage today with the setting you recommended...I am still not sure I have it right...BTW, the darkest ND filter I have is the 8, I will look into getting a 16 later.

That slight instability is caused by the aftermarket lens which is effectively zooming in past the ability of the gimbal and dampeners to hold the camera steady. No change in video resolution or size will effect this phenomenon. Check out my other posts above, this is not the stock lens.

TW, that looks a little better. I have never tried a narrower lens so I am guessing as EEV has, there have been attempts at different dampeners to try and minimize the shake but perhaps it may never be perfect. I must say that I do like the no distortion image and slight parallaxing effect when the camera is moving, but those shakes do stand out a bit too much. Though I bet it will take some nice stills.

100% on the money. The longer the effective focal length the better the gimbal has to be. The gimbal has to be tuned for the lens. If a camera or lens has internal stabilization, be it mechanical or electronic, they will always be set up around an average focal length. Electronic stabilization provides a wider range of stabilization. It’s why 800mm lenses are usually mounted on a tripod.

I see the jitter that's being reported watching it on my 5120x2880 monitor. As has been said, its most likely the lens/gimbal combo.

4K is tough for me to really get into on YouTube. I leave critical analysis of 4K for Vimeo uploads. The "stats for nerds" on YouTube don't always report the resolution correctly for me either.
