Masking problem occurs when I render a video

Hello,

I am working on a stop motion animation, which I have done using DragonFrame.

When I have imported the sequence of stills in Sony Vegas Pro 10, I have removed some parts with a mask (using keyframes,

frame by frame). When I checked the video in Sony Vegas, it looks perfect. However, when I render the video, it is as if the

mask does not even exist.

Can anyone please help me with this?

I am having a hard time fixing this.

Thank you so much for your time.

A screenshot of your mask window, the preview window & rendered output would help.

Hello! Thanks for your reply. Here is a screenshot of Sony Vegas and my mask and then a screenshot of the same second in the final video. It's as if it the mask does not apply on the rendered video.

However, in Sony Vegas I see it working perfectly.

Have you checked your keyframes?

The second shot is rendered at the exact same frame?

Need some explaining of what's going on. The shrimp(?) is the bottom layer, the hand is the top? You have the mask on the top event it looks like (both have pan/crop so not sure which). As there is black in the pan/crop/mask window that would mean it's complete solid black at that particular frame, but you have keyframes and show what it looks like at the other keyframes.

"Positive" in the mask means anything INSIDE the mask you drew will show through, so that hand would be what shows though and everything else would be transparent, but all the options in the mask are keyframeable so it's possible to turn that from positive to negative at different keyframes. Opacity could also be changed and that could change what you're expecting.
