"I see no pulsing"
I see "detail pulsing" on the tree, every 13 frames.
Please see with "Preview HALF" quality in Vegas.
Look. I made stepping frame by frame in the timeline and place a marker,
when i see some big detail changes.
The result is here
I don't watched the frame counter meanwhile, just hit "M" when changes appear. Do you see some normality at the marker position?
Yes, everyone follow the next after 13 frames.
This can't be the iris adjust, i just don't walked so precisely
And the GOPs are exactly so long..
Actually light was more than enough, the lens wasn't open wide, and the tree is not out of focus. It just don't have enough contrast for the realtime MVC encoder. I think because the background has very tiny details (especially on the ground, brown leaves), and this changes from frame to frame, the encoder need more bitrate! Around 16mbit is just not enough for full hd. Remember the other 8mbit is for depend view in MVC stream.
So because the tree is dark, and don't have enough contrast, the encoder
simplify this part of the frame, not to carry much attention (heavy compression)
And because at every 13 frames the whole frame are encoded again, without any reference to the previous, this looks good again..
"Come in from the other side with the sun to your back"
I will check it.
"The maximum bit rate for 24FPS here is 28Mbit."
I was in 3D mode, so i cannot change anything for the bitrate.
And it's 50i.
