Processing Delay of ATEM TV HD: "6 lines" in milliseconds?
Posted: Sat Dec 16, 2017 5:55 pm
I noticed, that the tech specs of the ATEM TV HD mention a processing delay of "6 lines" (compared to 1 line for the ATEM Production 4K and "<2 lines" for the ATEM Production Studio 4K 1M/E)
Could someone clarify for me, what exactly "lines" would mean here and how this would translate into milliseconds? Are we talking about "lines" as in 1080 lines in a full HD frame? (meaning anything less than 1080 lines would be less than 1 frame delay? and 6 lines would be somewhere around 0.3ms?
Or are lines basically fields or half-frames in an interlaced signal?
as in 1080i50 - 6 "half-frames" = 3 frames = 120ms delay?
Further, does anyone know, wether the actual processing delay depends on the use of DVE, DSKs and such?
I found older discussion of the original ATEM series saying multiview +1 frame, DVE +1 frame.
I'm trying to find out if the ATEM TV HD is in any way suitable for a live setup where on-location projection would be needed too. 120ms would be definitely too much.
Thanks for any input on this,
cheers,
Daniel
