Frame delay on NX70 HDMI output?
on May 22, 2014 at 7:27:08 pm

I've looking for a compact 1080p60 camcorder to use in a live production setting. I want to use HDMI output, because most of the rest of my system is also HDMI. And I need as little delay as possible, because I'm using a software video switcher (vMix) and the capture card and output from PC also add their own delays.

With the Sony HVR-V1U 1080i camera, I get a delay of about 30 ms on the HDMI output. My method of measuring the delay is to point the camera at a laptop running the timer at tft.vanity.dk/inputlag.html , connect the camera's HDMI output to an HDMI monitor, and then take a picture of both screens with a DSLR camera on a fast shutter setting.

What I'd like to know is how the Sony NX70U performs in this kind of test. I've tried a Canon 1080p camcorder and its delay is about 67 ms. Hopefully the NX70U is better. Would any NX70U users be willing to try this to help me out?

Here's a picture showing the test with the Canon camera:

How about NX30, then?

Please?
I would really appreciate if someone could try this quick test.

Alternatively, if it's done on the NX30 that would be helpful too.

Thanks.
