Ghosting

Hello All,

I am getting "ghosting" (it almost looks like it is showing the motion blur of the action, which I don't want) when rendering a QuickTime action movie and do not know how to get it to stop or why it's happening in the first place. Maybe I have something turned on the the program? Can anyone help me on this?
Please respond when you can.
Thank you.

Set your project frame rate and render frame rate the same as your media frame rate.
If your source media has pulldown you may have to jump through some hoops to remove it.

As musicvid said, make sure the frame rates in your project properties and rendering dialog are correct. And if you used slow motion, then you must select all video clips in the timeline and "disable resample" en mass before exporting. These two actions should ensure no ghosting.

Another possibility: if downscaling from HD interlaced source video to a lower resolution output, make sure you have an "interlace method" defined. In project properties, "Interlace" should probably be set to "Interpolate Fields".

If set to none, I think Vegas will downscale a "frame" of HD video by pretending it is progressive (even if it isn't) and scaling the original frame size to the desired output size -- even if the source video is actually interlaced and the even and odd scanlines came from different exposures.
