Hi,
today I finally received my GoPro HD and did some test flights with v2.4 and camera stabilization activated. Here you can see a little video taken in 1080p with acro and attitude mode:

But as you probably see I need to rebuild my camera mount because it vibrates too much and so the video quality is not the best...

regards

The go pro quality comes through. Keep the videos coming.

What was 0.85? Can't be for the 2.4 software?

Seems like it's all working good anyways! You might wanna check the motors/prop mounting since you hear that intermittent "squealing" at random frequencies.

It was just a blooper, I meant P=85 for acro mode. :D

Today I did some more tests, but my camera mount is still not resistant enough against vibrations. So we filmed our MultiWiiCopter by hand (a bit shaky):

Next time when I have found a suitable camera mount I will post some more videos taken with one of our 4 AeroQuads. :p

Hi All,

The higher frame rate (60fps) works better.

Looking good - your quad is nice and stable! Have you tried running image stabilisation software on the video? Deshaker is free and quite good, though I'm not sure how well it will fix those high frequency vibrations. http://www.guthspot.se/video/deshaker.htm

@alamo:
Thanks for the tip, but it doesn't really help much and after deshaking the video size grows beyond good and evil (over 25 GB, probably I did something wrong :D), so I will try to reduce the vibrations.

@Scott:
I will try that, but as far as I can see this is only possible in 720p and I would like to record only in 1080p, but anyway thanks for your advice.

DeShaker will not help with the jellovision effect on a GoPro too much. There is a rolling shutter setting in the software, you can try changing the settings. The jello look has to do with the rolling shutter of the camera and the frequency of the vibrations of the quad. High frequency vibes and a GoPro is a bad combo unfortunately.
You didn't do the DeShaking wrong, it outputs to an .avi file, uncompressed. You can use a different codec to decrease file size some, but its still gonna be huge. You need to then re encode to a proper size and file type, I like mp4.

@Scott: I have read the opinion that the 60p setting helps with jellow vision. I don't believe its true. I have tried both settings, with equal results. Perhaps the extra field of view on the 720p setting masks some of the effects, I am not sure.

Another day, another flight, another video :)
I rebuilt my camera mount and limited the servo's sweep on roll axis, so finally most of the vibrations are gone now.

Moreover I had my first night flight with my MultiWiiCopter today:

Just a quick update:
Today I had my maiden flight with my recently built up Mikrokopter (Hexa) and I have to admit that Altitude and GPS Position Hold are really impressive even in stronge winds like they were today. Also camera stabilization works really smooth.

Here's a short video:

Is that the landing gear moving around jsut to the left of the frame? If so that is some amazing camera stabilization.

Yep, that's a part of the landing gear. I'm also really impressed by this smooth stabilization.
