Simple settings for proper interlacing

Rootwitch wrote on 7/22/2004, 8:55 PM
Oh my goodness, could this be any more of a pain. There must be some default config for what I'm trying to do. I'm simply trying to convert VHS concerts to DVD, but high movement frames come out looking like this http://www.loudlove.org/richie.jpg - Now, not every frame looks like this - Only high movement.

I'm using a Canopus ADVC-100 capture device. I've got 'Lower Field First' set on the clip, the project properties, and when rendering. (Does one combat the other is set differently?). I've got "Reduce Interlace Flicker" checked on the clip. The clip is 720X480. I've got Deinterlace Method set to Interpolate.

I've read through a lot of posts here relative to interlacing, but haven't found an asnwer that works. Now, to watch the DVD on TV, it's not terribly noticable, but it's there.

Is there something I need to config before capturing? Did I capture incorrectly, and nothing I do after the fact will correct this? I've spent the last 2 days reading and testing -- Please help....

I never have this issue, however this is my method.

Capture in AVI lower field first.

Into vegas with project settings set to Deinterlace method Blend fields.

Frame serve to procoder 2 with the mpeg set to top field first.

You don't need to de-interlace if going out to normal DVD!

The only time you need to de-interlace is when making a 24p DVD and for something captured from a VHS tape that'd not be a wise move. If it's from film as far as I know there's no way for the field cadence to be preserved so the pull down removal could be all wrong.

So ignore any wierd interlace problems you see on the PC monitor, they're normal, in fact worry if you don't seen them. Project settings should be Lower Field First, the default NTSC template.
Then encode to mpeg-2 using the DVDA NTSC 720x480 template. For best results turn on 2 Pass encoding, may or may not make a noticable difference.
Then seperately render out the audio as a .wav file 16/48K. If the video is less than 1 hour it'll fit no sweat.

I think you've treid to fix a problem that wasn't there and created a real problem in the process.

Do the capture with Vegas,
If you wanna watch it on TV keep it interlaced(assuming that you're not using ProgressiveScan TV),
Start new project in Vegas,go in the project properties,click the "Match Media Settings Button" the field order will be set by Vegas, so you don't have to worry about wrong field order.

"Capture in AVI lower field first.

DO NOT DO THIS ! ! !

Encoding the video with wrong field order results in jerky playback, if you watch it on TV do not DeInterlace, no need for that.

when you try viewing it on the TV and there is inerlace problems, only THEN change the field orer of the clip & see if it still happens.

I capture via an analog card that capturesthe fields backwards. Vegas says it's lower field first but it is really upper field. So, I change the clip to upper field & render the mpeg out to upper then it's ok. However, I tested rendering different ways EXTENSIVELY before I can to this conclusion, and you shold to (because it shouldn't be).
