Interlacing Issues during fast movement in Veg10
I’m rendering out an HDV project in Vegas and it seems that no matter what settings or format I output to, there are major interlacing issues in the rendered video. One thing to note is that I shot some footage Progressive and some Interlaced (with a Sony Z7U and Z1U). The problem is with the interlaced footage.
I’ve set the project settings to match the HDV interlaced footage and outputted to AVI DV Wide, DVD Arch widescreen template, outputted to Upper field, lower field, and progressive. I’ve even tried to output to HDV 60i and I still get interlacing (only thinner lines).The way I’m finally able to get rid of them is to render out in Preview Quality (instead of Best Quality). (Just figured this out as I was typing). This work around works for me, but I’m wondering if I’m losing some quality. Were you guys aware of this? I’m curious if you get the same results when you render in ‘Best’ quality.
Thanks guys!

DV Widescreen is an interlaced format and you should have interlacing. Why is this a problem? Are you seeing interlace artifacts when you watch the DVD on your TV?

Sorry. My initial post was unclear. it appears very ‘jaggy’ when there is motion. Some jagginess is expected with interlaced footage, but this is extreme and the interlaced lines appear very thick. It looks as if the odd and even fields are out of sync with each other by a few frames. I tried to attach a video still of the problem to this post, but it instead started a new post…so I don’t know what happened to that pic. …but it should be somewhere in this forum?

Set your project settings to progressive and field order to blend and render to progressive as well you will see no interlace lines.

This sounds like you may have resized the interlaced footage and it didn’t properly deinterlace. In your project properties, what is your setting for the Deinterlace method?

Danny,
Came along this thread after a google search. This worked perfectly. I’ve been struggling with this for a long time. Footage never “looked” progressive until I applied these settings. I created a Creative Account just to thank you.

Your welcome Lonnie. Sometimes I set my preferences to Progressive, field order to interpolate, if the video isn’t too fast, it looks even clearer than blend. But if the video is fast moving, it can look jittery. Also, welcome to the CreativeCow forums.
