THE BEST IMAGE FROM A INTERLACED SOURCE...

DigiMortal wrote on 7/29/2004, 3:33 PM

I have a video captured with a Pinnacle DC10+, which this in format NTSC - 29,97fps - MJPEG - 640x480 and by defect has field order in UPPER FIELD FIRST.
I need to make a DVD with this video.
Setup used in Vegas is:

1. Project properties:
- Template: ntsc dv (720x480)
- Width: 720
- Height: 480
- Field to order: lower field first
- Pixel aspect ratio: 0,9091 (ntsc dv)
- Frame rate: 29,97 (ntsc)
- Full resolution quality: best
- Motion blur type: gaussian
- Deinterlace method: blend fields

2. In the timeline:
- Switches: reduce interlace flicker, smart resample

3. Render as:
- MPEG 2
- Template: DVD Architect NTSC video stream

Once renderized, soft horizontal lines I can see.
I have proven changing some parameters, but no obtain the necessary quality.
In the commercial DVD that I have seen, the image is nitid and without lines that obstruct his vision. My objective is to obtain this.

¿How I can obtain a video without interlace signs?, ¿what is the correct setting for my type of video?.

Many Thanx...

DigiMortal.

I thought the project properties are supposed to match your footage.

I've noticed that even though some files SAY upper/lower field first, they can actuatly be the other one. I'd recomend trying this:

set the clip to upper field first. Render out a 5 second mpeg-2 (upper field first) for DVD.
Set the clip to lower field first. Render out a 5 second mpeg-2 (lower field first) for DVD

burn those to a DVD-RW disk & play on your DVD player. The one that doesn't have interlace problems is the way you want to use the footage.

I've done this many, many times because (aparantly) my old analog capture card captures in the wrong field order, BUT the file is labeled in what it SHOULD be. That's when I discovered that if I do lower field first then everything is A-OK.

I have already proven doing the suggested thing, but... smooth horizontal lines again.
Now, I am going to change a little the question:

¿How YOU can obtain a clean image of video, without signs of interlace of a source like which I describe above....?

Thankz
DigiMortal.

PD: this subject about how to eliminate the interlace is more difficult of the hoped..

Make sure you view the results on a real television monitor, rather than on the computer screen. Make a test DVD, if necessary (if your player can read DVD-RW or DVD+RW, use one of those to avoid creating a disc you might not be able to use). The reason I suggest this is that your computer monitor may show interlacing lines (this is normal, in fact) whereas the video will look normal when played on a TV set. Thus, you might not need to do anything different at all.
