Interlacing on DVDs?

Can you post a picture screenshot of your Project Properties? Let’s start be using how you have your project set up.

Here’s the picture. BTW, I wasn’t ragging on Vegas in my OP, its been my NLE of choice for years, I just can’t figure out why it’s putting out the footage this way.

[John Rofrano]

Your project properties are fine for delivering HD but you are delivering SD DVD. I’m wondering if Vegas Pro is interpreting the 60p as 60i when it renders to DVD?

Try this… start a new project but set the frame rate to 29.970 to match the DVD. Then drop a piece of footage into the timeline, right-click on it and in the Properties, check Disable Resample. Then render that to DVD and see if it fixes the problem.

Disabling resample and loweriing the project framerate didn’t solve the problem. The only choices for rendering to DVD at 720×480 16:9 are 60i or 24p. Rendering at 24p gets rid of the interlacing, but it’s 24fps, which negates the whole point of shooting at 60fps.

Edit: If it helps, here’s a picture of what I’m seeing in the finished product at 60i

Sean,
on your project properties you have a de-interlace mode set for progressive footage. I don’t think you need that and it may be doing some harm, i.e. contributing to the jagged lines. Set it to where it should be for progressive footage, i.e. none.

Are you trying to get half speed on the DVD?

If you want to post a short clip somewhere it will be easier for others to help resolve the problem.

[Sean McNally] ” Rendering at 24p gets rid of the interlacing, but it’s 24fps, which negates the whole point of shooting at 60fps.”

Well… there is no point in shooting 60p if your delivery is on DVD because DVD doesn’t support 60p. They only support 29.97 fps so that’s all you will ever get.

[Sean McNally] “If it helps, here’s a picture of what I’m seeing in the finished product at 60i”

Was that image taken from DVD Player software of just Windows Media Player because WMP might not be smart enough to deinterlace the footage.

I must say that the interlace lines look too big to be normal interlacing. Did you zoom in at all? That looks like zoomed footage that wasn’t properly deinterlaced.

Right-click on one of the clips on the timeline and select Properties and go to the Media tab and post a screen shot of the media properties. I’d like to see how Vegas Pro is interpreting your footage.

Tried this, did not fix the issue.

[John Rofrano] “Was that image taken from DVD Player software of just Windows Media Player because WMP might not be smart enough to deinterlace the footage.”

It was taken from VLC media player. I could manually turn on the de-interlace feature during playback in VLC, but that makes motion blurry, which is not what I want for this project. The reason the de-interlace lines look so big is because I cropped the screen-grab to emphasize what you should be looking at.

Here you are:

If I render it out normally it will look fine, it’s only when it renders in DVD format that it looks this way.

[Sean McNally] “It was taken from VLC media player. I could manually turn on the de-interlace feature during playback in VLC,”

The reason you are seeing the interlaced lines is because you are viewing on a monitor that does support interlacing and you did not turn on the deinterlacer. You should burn this to DVD and watch it on a TV and then see if you still see the lines,

[Sean McNally] “…but that makes motion blurry, which is not what I want for this project. “

You are not going to get smooth 60p playback on a DVD. You don’t have much of a choice if you are delivering on DVD. All you get is 29.97fps.

Alright, thanks. One last thing, if I’m rendering at 24p, is there any benefit to shooting at 60fps, or should I set the camera to 24 or 30 fps next time?

There is no benefit to shooting 60p if you are delivering 24p. You really should shoot 24p so that what you see in the camera’s viewfinder when shooting is what you will get on the timeline. The only time I would shoot 60p is if I needed to do a slow motion effect. Other than that, if you are delivering 24p I would shoot 24p.
