How can I tell If I deinterlaced my video after CCE2.67 encoding?

[videocheez]

I have been reading a little bit about deinterlacing my video and came to the conclusion that i should only deinterlace if I plan to show my video on the computer monitor.
I have been using premier to edit some DV of some home movies. In one case I deinterlaced the source using premiers deinterlace tool and then converted the movie to wmv for web transmission.
For the second conversion, my intent was to convert the video to mpeg2 using CCE and then author to DVD for viewing on the TV. I used the following script for cce:

AviSource("C:\1movie encoding\cce\huntington\huntington.3na.avi")
Complementparity
SeparateFields()
BicubicResize(688,224,0,0.6,0,13,720,214).Weave()
AddBorders(16,16,16,16)
Trim(0,17293).FadeOut(150)

In CCE 2.67, I unchecked the progressive frames flag and chose alternate scanning. The resulting mpeg2 video plays nicely on in media player and I don't see any interlace lines so I'm concerned that I may have deinterlaced my source when I did the meg2 encoding. The DV original had interlace lines when I paused or panned the camera sideways and they are annoying on media player but I read that I would get a clear picture on the TV by not deinterlacing any video that I did not intend to watch on my computer. I used a template that I picked up here at doom9 called CCE_267_templates.reg, some time ago and it has an interlaced video template. I used that template to encode and since i dont see interlace lines in media player I'm wondering if that template deinterlaced my video, or if my avisynth script deinterlaced it, or if the encoding is just wonderful and doesn't appear to be interlaced anymore. I used the standard matrix settings.
I guess i want to know how can I extract that template from cce to post here to see if I deinterlaced my movie or if there is a program that I can point at my movie and it will tell me whether it's interlaced or not.

Thanks in advance,

Well, you didn't deinterlace the video in your script. CCE doesn't do any deinterlacing IIRC so your video should still be interlaced.

Try to load the CCE encoded file in DVD2AVI (or VirtualDubMod) and look for the combing. It could be that your display adapter automatically deinterlaces the output.

Okay, I took your advice and opened it with vdubmod and I could see the fine tooth combing. Perhaps media player cleaned up the video a bit.

Thanks for the time,

If your interlaced MPEG2 is encoded properly, you should never see interlacing artifacts on playback, as it should be deinterlaced to 60fps on playback.

Do you mean that I should never see interface artifacts even on a computer monitor. I was just following the advice that i read in the following guide that says basically should only deinterlace if you plan to show your video on a computer. Check out the comments at the following URL:

You'll see the combing on your monitor but you should not see it on your TV. PowerDVD and WinDVD also have a deinterlacing option so they'll show you the clip without the combs.
