Motion Blur after render at different framerate even with disable resample
So to produce a “stutter” effect in one of my clips, I used undersample to reduce the framerate of the clip. That means the project is at 29fps and that individual clip is at 14fps.
When I play it back in the timeline everything looks fine, I get the exact “stutter” effect I was looking for. However once I render the video using the Internet HD 720p 30fps preset, I get a ton of motion blur on that clip. A quick google said that switching that clip’s properties to “disable resample” should make it just drop half the frames instead of blending them, thus eliminating the motion blur. However this did not work, and the motion blur did not improve much if at all.
Again, the blur is not there when I preview in the timeline, but appears after rendering.

Try right click on the clip and switches – reduce interlace flicker.

That had no effect.

Have you tried changing to progressive scan when you render?
-
I believe it already is. Field order for the clip is set to none (progressive).
Which option are you referring to?
-
Its only if you are rendering to mpeg, you can change the field order in the custom tab. If you are rendering to wvm there is no option.
-
Yep, that is already set to None (progressive scan), and I still get the motion blur after render (but not in the preview window).

Also, I recently found the “disable motion blur” button on the timeline of the video track, but selecting that (even if I do it for all tracks) doesn’t help either.
This is ridiculous. Vegas adds motion blur to prevent stuttering with a lower frame rate. But I WANT it to stutter. Why can’t I tell Vegas that?
-
Hmmm, so apparently the clip had someone gotten the field order set back to “lowest first”, which apparently overrides the project settings.
However, changing it back to None (progressive scan) greatly reduces the motion blur, but at the same time it shows up badly interlaced (the original clip was interlaced). It’s weird because it doesn’t show up interlaced in the preview window, and even weirder because After Effects has absolutely no problem rendering the same clip with no interlacing or motion blur.

Ok, I finally got it fixed.
For anyone out there that comes across this from google, the thing that finally did it was changing interlace method from Blend to Interpolate. This finally got rid of the blur.

Hi there,
I’m having the same issue as you with motion blur on my video, but being fairly newbie at vegas, I’don’t know how to do the above to try and fix it.
I have Vegas 9 – can you offer some instruction on how to set the interlace method pls?Many thanks!
