I'm starting a documentary that will be placed on one of the major networks or regional PBS. We are doing some of the shooting with JVC gy-hm750's. Footage will be shot in 1080 24p. Does anyone have a recommendation on setting the nanoflash in a sweet spot for better visuals (vs the 750's 4.2.0 and 35mbps) and a Mbps rate that will satisfy the networks?

What do you say Dan K?

Network minimum is 50Mb 422 LGOP or 100 plus I frame

100Mbps L-GOP is popular with many EX1/EX3 shooters, this should more than work for your JVC as well.

I would shoot 100Mb/s LGOP, that is where my Nano lives.. It lets editors who need 50Mb/s to have some head room with the extra bits.

I really like 140mbps I Frame. There is a lot of headroom for color correction and you are not using that much more card space compared to 100/long GOP. Recently, I have been recording 1080p/24p out of my HDX900 with amazing results. It has given new life to this camera.
