Field settings when rendering to DVD - help please

bearded wrote on 7/21/2002, 3:26 PM
I have been trying to generate DVDs from interlaced source material with a combination of upper field first and lower field first material.

I assumed that it would be best to select a progressive output. However this generated horrible flicker during playback on a TV

Can I assume that if I render out to DVD option and select lower field first option then all the upper field first frames will have the field order reversed ?

Many thanks

your progressive DVD shouldn't be flickering on your TV. Vegas should take care of that. you may want to double check your source files. right click on each source file in your media pool and hit properties and verify that the proper field order is selected. then go to project properties and make sure you've selected progressive.

if everything looks correct, you should try the 'reduce interlace flicker' switch on each of your events.

as long as your source files are showing the correct lower/upper field first settings, Vegas should take care of any field order issues for you. so you can safely render to a lower-field-first format rather than progressive and everything should look correct.

lots of 'should's in this post. :/ hope it works for ya!

Cheesehole,

My problem is that when I try and find out the properties of the clip, as you suggested, it comes up as progressive when I know it is not !

The video is captured using MJPEG h/w compression (Matrox G400-TV) which should be upper field first. However for some reason this is not always the case.

So I thought..... that if I set the output to progressive then I would not get problems changing from one field setting to another

Looks like I have underestimated the problem

So do you know any way of reliably resetting the field setting to be uniform and consistent

Thanks for your interest
