Question

Possible Conflict between Record & Video Out - Sony NX5U

Good morning

We are using Sony NX5U as one of our cameras for streaming a hockey game.

1. We send the video out via the SDI port at 1080

2. We simultaneously record on a SDHC card

a) When we record at 720 there are no issues

b) When we record at 1080, my guys say the video appears jittery in our streaming broadcast.

Could/should there be any correlation between the recording format and effect on the streaming feed via SDI ?

The SDI video out goes to an ATEM TVC mixer

Thanks

Whit

My bet is 1080 pushes the capability of the product.

Put another way, it doesn't have the horsepower to do both. You may have to confirm with Sony but this sounds like it to me.

Another possibility is

the network connection somewhere along the line is not robust enough. You said, "video appears jittery in our streaming broadcast".

What we don't know:
* what is upstream of the ATEM TVC mixer (network being used);
* what the viewing devices are on the receiving end;
* how the viewer's devices are connected (i.e., wifi, LTE, wired Ethernet, something else) to receive the video... and if the devices are on a shared network we don't know how busy that network is...

My suspicion is the NX5U, while not designed to be a studio-type camera but being used as one, is OK.
