Problems with 720/30p in Vegas with ghosting

[AlanB]

I am new to HD and shot a project in 720/30p and used the HDV 720-30p template in Vegas. My question is, if I look at the event properties for a clip it is showing the Undersample rate as 59.940. I am assuming it duplicates the frames at this rate. Is that correct? Is this done in the HMC150 or with Vegas?

Here is the issue. When I render it out, there is some nasty ghosting on any movement. If I reduce the Undersample rate to .5 which is 29.970 fps, the render looks perfect.

Do I have to go into every clip and change the Undersample rate to fix this or is there some global setting that will fix this? I tried changing the Project Properties Deinterlace method to Interpolate fields, but that didn't help.

This is really frustrating. Any help would be appreciated.

Change field order to NONE.
I don't use vegas, but 720 footage is progressive, and it seems as if you are using an interlaced setting.

It's because the 150 records 30p in a 60p stream. In other words, every frame is represented twice.

Changing the undersampling may be the only way to do it, at least for now.

Changing the Undersampling isn't too big a deal. I can change one clip on the timeline and then copy and paste the properties to all the rest of the clips. What's one extra step. :)

How do you copy clip's properties and assign it to other clips?

[David Jimerson]

Copy the clip. Select all the other clips; right-click and choose "paste event attributes."

This must be done on the timeline.

Wow, thanks for the tip!
