Need help with deflickering of video of projector screen
I shot a video of a technical symposium in which the speakers used a PC attached projector. I am getting a great deal of flicker on the shots of the projector screen. I have experimented with both the Donald Graft and MSU deflicker filters in VirtualDub without much success.
The video was shot with a Sony EX1R at 1920 x 1080, 60i. I would appreciate any suggestions. |

Have you played with the ECS FREQUENCY settings, page 51?

I haven't tried ECS. I would love to know more about it. Sony's brief two sentences in the manual don't give any application tips on it. If anyone has any helpful links, please post.

It sounds like you're experiencing the moire effect, this happens when you shoot a high resolution video display. You could try de-tuning the video by adding a slight blur or soft focus over the shot of the screen, it might help. |
