Hi, I imported a jpeg into Boris FX 6.01, animated it the way I wanted, and then came back to Media100.

When I render it, it flickers.
In some shots of animated videogame screen shots, the flickering makes it look like certain elements in the picture are flashing.

I just went into After Effects and did the same, and had no problems. So I've achieved the effect I wanted to achieve, it's not hindering my work.
But it would be nice to do it in Boris FX and Media100 in future, so I don't have to leave the programme and go into After Effects.

My guess is some sort of anti-aliasing is going on, creating problems when things move. Or maybe it's a lower field / upper field thing. But then it's a still picture imported, not footage, so I don't have those options in the media panel.

Interestingly, if it's just a still image, non-animated, it doesn't flicker in the Boris Preview, but does when rendered.

And FYI both images were scaled up a couple of hundred percent.

I have Media100 7.5 in OS9,
G4 Dual 400 Gigabit Ethernet
Boris FX 6.01

Hi Ajmetz,

The problem is interlace noise as you suspected. It can be solved by engaging the "1:2:1 deflicker" option in the local project settings of the Boris Preferences pane. The picture gets a little softer but you lose the flicker.

In some cases I find the softening actually improves the feel of the picture.

Hope that helps
