Lip-sync tests

I have just installed my LG G3 OLED tv as my reference monitor and I was supprised how much delay there was on the picture. My older Plasma tvs had about 60ms delay.

This is my setup, Premiere Beta running on a 9900 i9 based PC feeding a BM Ultra Studio 4K mini. The LG tv is then fed via HDMI and the BM analogue audio goes to my monitoring.

The test I set up had a Prores file with black for 2 sec followed by bars and tone at 50 fps.

I configured my Racal Universal timer so that the audio started the count and the white of the colour bars stopped the count (via a photo diode trigger)

These are the delays I got ( all delay settings in Premiere set to zero) from different sequence settings

50 fps      108ms

25 fps      168ms

60 fps      90ms

30fps       147ms

Playing from the Source monitor     110ms

This is the same test done in AFX

50fps        180ms

25fps        270ms

60fps        181ms

30fps        240ms

and in Resolve

50fps        145ms

25fps        112ms
