Deinterlace method setting for NTSC DV, 29.970 fps? at DVinfo.net

James Binder · February 20th, 2007, 12:53 PM

Shouldn't the ‘Deinterlace Method” (under the video tab in project properties) be set to NONE when working with an NTSC DV, 29.970 fps (template) project?

My current project is intended for DVD -- to be played back on standard NTSC televisions. The source video is standard 4x3 DV and captured as such.

I know this sounds like a silly question, but I wanted to be sure. For some reason, my project properties has this set to ‘Blend Fields” and I’m pretty sure this is not correct -- insomuch as I do not want to deinterlace the project or footage.

Shouldn’t the default for a NTSC DV< 29.970 project be ‘none’?

Thanks --

No. That's the option you use if your footage is progressive.

The deinterlace method only comes into play if you render to a progressive template. You don't want to set a deinterlace method for progressive footage.

David -- thanks for the reply -- I'm a bit confused though by your responce. My thickness, I'm sure!

My footage is NOT progressive -- just plain old NTSC DV 29.970 (shot 1/60 with XL1s)...

Maybe this is a better way of phrasing my question:

What is the correct ‘Deinterlace Setting’ setting for footage shot 60i (with my XL1s) and captured NTSC DV 29.970 – with the final destination being DVD for playback on standard TVs? My thought is that it should be set to NONE. Yes, no?

If anybody else would like to chime in as well, I'd appreciate it --

Thanks

EDIT:

Looking back on this, you may have been asking something slightly different than what I thought you were asking. My fault.

The default for NTSC DV *is* "None."

No. I don't think so unless I'm way off base here. The default setting for deinterlace method in Vegas is 'blend fields'. However, it doesn't matter unless you change the field order to None (progressive scan). If you leave it as interlaced footage (NTSC DV, lower field first), there will be no change in the preview look. In order to convert it from interlaced DV to deinterlaced DV, you would have to set progressive in the render template under the custom tab.

This is what my default is.

Now, I rarely ever go into an NTSC DV project, so I never had any reason to monkey with it.

James Binder · February 20th, 2007, 06:47 PM

Thanks David – Thats what I thought.

GUY – I do not want to deinterlace here. Unless I’m way off, I’m thinking that my footage (as noted above) needs to stay INTERLACED. Again, I do not want to deinterlace.

So then, with a NTSC DV 29.970 project (which is intended for DVD playback on standard TV) the deinterlace mode (in project properties) should be set to 'NONE'....I hope.

For some reason in my current project, it is set to 'blend fields.'

I’d be appreciative if somebody could confirm this before my head explodes…

Vegas's default settings are optimal.

James Binder · February 20th, 2007, 11:20 PM

Thanks again David -- none it is then.

I’m not sure why, but again, in my project settings it was set to 'blend fields' -- which was causing blur when graphic/video items moved vertically on the screen. It was particularly a problem after using the event pan/crop function and merely sliding down the source video for better composition (within the safe areas) -- this caused very noticeable blurriness.
