nanoflash EX1R limit?

The nanoflash can record up to 280 Mbps from the EX1R. But isn't that top rate unnecessary?

What I'm asking is: does the 100mbps recording from the EX1R look better than the 50mpbs? Does the 280mbps recording from the EX1R look better than the 100mpbs?

thanks

Any idea why that would be? Seems like it would be just the opposite....(?)

I've read that over 100mbs on the EX1R is noisy, so not sure how 280mbs is better, but don't know from experience, only what I read.

Piotr ~

How do you know that 100mbps doesn't look better than 50mbps? and that 180mbps DOES look better than 100mbps? from your own experience? or can you point me to the info?

thank you!

I thought you wrote 280 (not 180) Mbps in your OP. It's the 280 Mbps I-frame that gives the best results with the nanoFlash.

As to Long-GoP 100 not "looking" better that 50 - this holds true with the EX series cameras which are quite noisy. With lower bitrates (like 50 at 4:2:2, or 35 at 4:2:0), the compression is high enough to mask this noise a little. With 100 Mbps and up to 180 Mbps L-GoP, the noise gets augmented.

HTH

Re: nanoflash EX1R limit?

I concur with Piotr. If you want a good read, go find his very long thread in the nanoFlash forum.

I find the Picture Profile settings even more important when using a nanoFlash at high bitrates mainly due to noise. I can't recall my settings, but I turned the sharpening settings down quite a bit (I think frequency and crispening) in order to reduce noise.
