View Full Version : Trigger - AVI- Codec question

June 1, 2007, 07:31:19

I use the 31BF03 to capture stills to AVI, using IC Capture and the camera trigger. This works very fine, but if I use the Huffyuv losless codec or the Microsoft DV codec this is what happens:

These codecs are adding 'D' frames between the keyframes. The keyframes are the original 'triggered' frames. If I capture very slow (1-2 frames/sec) I get more 'D' frames. It looks like these codecs are looking at the camera's frame rate and are trying to fill the gabs in time with 'D' frames.

If I capture uncompressed, everything works fine. One trigger = one AVI frame, no matter the recording speed. I have only tested uncompressed RGB24 for now, but it works.

Of cource these files are h-u-g-e.... is there another way?

Thank you,

You can try to use a codec from here:

LEAD MJPEG2000 Video Codec seems exactly to do what you're looking for ...

Hello Elha,

Thank you for the suggestion!
I will try the Lead Mjpeg codec evaluation.
