PGVV is apparently a video codec generated by either the Video Vision hardware grabber card, or with the Radius Studio software. All the brochures and reviews say that it is using an "adaptive JPEG". Probably it means adaptive rate control as described in their patent 5,621,820. There are some lossless conversion utilities to MJPEG-B, thus it should be very similar to standard JPEG.

PGVV is apparently a video codec generated by either the Video Vision hardware grabber card, or with the Radius Studio software. All the brochures and reviews say that it is using an "adaptive JPEG". Probably it means adaptive rate control as described in their patent 5,621,820. There are some lossless conversion utilities to MJPEG-B, thus it should be very similar to standard JPEG.

A quick look at the header of the frames tells the following:

 32bit always zero?
 32bit always zero?
 16bit ? (was 0001)
 16bit ? (was 0020)
 32bit ? (was 00000008)
 32bit always zero?
 32bit ? (an incrementing field, in the only sample: 480, 512, 680, 1284, ...)
 32bit always zero?
