Inserting deinterlaced clip into interlaced project
 

I'm forced to steady a clip using vdub's deshaker filter which works best deinterlaced. However, the rest of my project is interlaced. Is there a proper way to insert a deinterlaced clip into an interlaced project? I'm going to render the project to m2t and running vegas pro v10.
Thx

Your workflow should be

60i -> deinterlace -> 60p -> deshaker -> 60p -> weave -> 60i

If you are feeding 30p to deshaker, then you have thrown away half of your source video.

It shows how to do the deshaker in vDub properly here

If you deinterlace to 60p, you don't really have to reinterlace the clip.

You mean once dropped back into the timeline, sony vegas will re-interlace to the project specs?

Hi Art

Most of my weddings have interlaced footage from the main cameras and then progressive from my GoPro Hero ... as long as you set de-interlace in Project properties to either Blend or Interpolate then you can drop in already de-interlaced footage into the timeline with no issues!! Render will apply interlacing to the entire timeline if you have specified it in the render options or the template or used a template that has interlacing specified...just add the stabilized footage and render as normal

It will when you render.

I'll give it a shot.
Thanks all

Actually, it previews/renders in Vegas with black bars on the top and bottom with the project settings NTSC DV (720x480, 29.970 fps). The only way I can get it full screen is to add the final interlace filter in vDub then import to Vegas.

The bars don't have anything to do with interlaced/not interlaced. It has to do with frame shape.

Re: Inserting deinterlaced clip into interlaced project
 

I told deshaker to match the input size and even set it to 720x480 manually. Media info shows this to be true but sony sees it differently and adds black bars at the top & bottom. It's only when I uncheck maintain aspect ratio that it displays perperly at full screen and is all put back together by vegas.

Re: Inserting deinterlaced clip into interlaced project
 

As it should be! 720x480 has the aspect ratio of 3:2, so unless your project has that ratio you either have to add black bars or stretch it to 4:3 or 16:9 or whatever ratio your project uses. 3:2 is wider than 4:3 and less wide than 16:9. Wide screen DVDs adjust for it by setting the PAR accordingly so stretching a wide screen video to 16:9 or squeezing the full screen video to 4:3 is the appropriate action.

So, if you want to keep the 3:2 ratio of 720x480 in a 4:3 project, you need to add black bars above and below the image. And if you want to keep the 3:2 ratio in a 16:9 project, you need to add black bars left and right.

But if it comes from a DVD, the PAR is never 1. If it is a full screen DVD, you need to fit the 3:2 ratio of the video file to a 4:3 monitor (old style TV). And if it is a wide screen DVD, you need to fit the same 3:2 ratio to a 16:9 monitor (modern TV). The concept is similar to anamorphic film, though the ratios are different.

Re: Inserting deinterlaced clip into interlaced project
 

You don't have to do anything with "Maintain Aspect Ratio." You just just need to change the pixel aspect ratio of the clip from 1.000 to what it should be -- 0.91 for 4:3; 1.21 for 16:9.

And again, this has nothing to do with interlacing.
