Hi All
When I take .avis of, say, Jupiter, using my DBK21AU04.AS camera, I am getting a series of lines - this I think is the Bayer.
What video codec should I be using, to eliminate or minimise this.
I am processing the images using Registax and with only a small amount of wavelet action these lines appear. See the attached file.
Your help and advice would be appreciated.
Cheers
Frank

Hi,

From my point of view, and this is a first guess only, the stripes do no come from debayering. I suppose, the stripes must be nearer, if they come from debayering. I did not check the distance of the stripes right now, therefore, I can not say more at this point of time.

Which video format and codec settings did you use? Both "Y800"?

Hi Stefan
No - Video Format was: Y800 and Codec: DV Video Encoder

From your question, I assume that I am using the incorrect settings!!

Outch!
The DV Video Encoder changes 1) the resolution, 2.) compresses the image data.

Use Y800 as codec.

Sorry to cause you pain ;-)
I'll change to Y800 for the codec and let you know how I get on
Thanks

I think the lines are related to a debayering process. My own recent tests seem to confirm this. I have also had similar issues to yours debayering in Registax. However if I debayer first using Virtual Dub I do not get the lines.
