Hello SonotaCo:

I tried to get rid of flickering distant lightning to no avail . is there a good setting in video trigger to se to ignore wide area ( pixels sudden increse in brightness -eg due to lighning?)
I still have stars in my FOV?

Also for some unknow reason - i have a ' fail to connect to avi source' problem and the sw close down. Earlier while playing with settings - i got "... invalid parameter things" Any idea what conditions in your coding that output these type of errors...

Thanks

Hi all:

Why not try on ligtning I thought to myself ? So I replaced my watec 902H with a color 1/3 CCD - integrating camera , put on a 12 mm lens and try to capture the lightning.

To prevent over exposure i chose 1/750 sec and run UFOCapture in the background . After a few trial and frequent moving the lens to follow the lightning clouds I finally got this one - to show you folks.

I hope you like it...

Yes, if you want to ignore flashes , Try EXsize = 0 and Min(frm) =2 or 3
This means flashes which do not have duration more than Min(frm) will be ignored regardless of its size.
This may decrease captures of flashes though it is not perfect.
But I do not like this setting, because it aborts all chances to get Sprites.

"UE059: Failed to connect AVI file source" means DirectX cannot open the avi file as a source file at the moment.
I am not sure what is happening. But I think it depends on system performance.
If the previous DirectX task delayed very big (it means the limit of CPU or HDD) system may confuse and go to panic.
It is the problem of entire DirectX which I cannot handle.
In my experience, there are very little problems when CPU load is under 60%.
If you can reconfirm the detail operation, I can research possibilities.
