Hi, I have some trouble in making adaptive gamma when previewing in low luminance condition.
The symptom is as follow.
1. there are 2 gamma curve(gamma curve #1 and gamma curve #2) I have and when DM365 is in normal luminance condition, the gamma curve #1 is adapted. And in low luminance condition, the gamma curve #2 is adapted.
2. This change in gamma curve happen in real-time by AE engine
3. The problem is, when the gamma curves are changed, the adapted frame is not synced, which means the scene that gamma curve #1 was adjusted and the scene that gamma curve #2 was adjusted exist in same frame. That causes that in one frame, there exists two different scenes which have different brightness.
4. So, what I want to know is
1) when I adjust gamma curve by using davinci previewer, which time the adjusted gamma appears in scene? ( I want to know it is synchronized with VD signal or not)
2) If gamma is not synced with VD, then is there any other way to sync it by software?
3) I'm not sure it is controlled correctly or not. So,please can anyone help me to get correct information to control gamma in real-time?
Thanks and regards.
