A few bits about EX1 shutter, blurs and transfer

[Steven Thomas]

Matthew (from another forum) shows that the EX1 resolution does not change during pan.

I believe this really is all about motion blur. I know with myself, this camera produces some of the sharpest detailed images over previous cameras “I’ve” owned, especially is the sub $10K USD market.

I believe some of this perception is from having this much detail and then moving into motion blur. It’s just more noticeable.

Even watching Hollywood HD productions I can clearly see the large diffence between still footage and camera pans adding motion blur.

I first heard about the EX1 going soft from movement from Barry Green’s EX1 review. Since then, I performed quite a few tests at higher shutter speeds and frame rates and moving images look fine. If the perceived additional blurring was due to some sort of slowing due to signal processing, it surely would not improve at more demanding higher shutter and frame rates. Also, Matthew’s tests show no rez lost during his pans.

Hi Ron-
Sorry I missed this post, way back in January. When you have a moment, check out our Flash XDR portable HD recorder, which is based on the Sony MPEG2 hardware CODEC. Flash XDR can record in both Long-GOP 4:2:2 full-raster MPEG2 at 50 and 100 Mbps as well as I-Frame only 4:2:2 full-raster at 100 or 160 Mbps.

We plan to record some panning video footage using Long-GOP and I-Frame only modes (and post on our web site). I do suspect that the I-Frame only 160 Mbps rate will essentially eliminate all these issues you discussed.
