Hdv render problem
The timeline contains m2t clips which are rendered using mainconpect down to WSDV ready for import in DVDArchitect. Playing the resultant mpeg shows pixilation were the action is fast. (eg flapping butterfly wing)s. This file is not of a sufficient quality from which to make a DVD. The same shots taken in SD, imported as an .avi and prepared for DV via mainconcept are OK (no pixilation).
I can get round the initial problem by printing to HDV, and importing the m2t file into DVD Architect and making the DVD from this file. There is no pixilation and the resultant DVD is a pleasure to watch.
I’m sure this is not the way to handle HDV. What am I doing wrong. -

What template are you using to render to DVD? You should be using the DVD Architect NTSC Widescreen video stream (or PAL equivalent) template.

Thanks John,
I did use DVD Architect PAL Widescreen video stream template. The same one that I have used with normal DV.
Sorry too much ‘shorthand’

Problem solved
File->Project Properties
Changed
1) Full-resolution rendereing from Good to Best.
No visible improvement2) Change Deinterlace method from None to Interpolate fields.
This later changed fixed things.I knew the field order was swapped between HDV & DV. It didn’t occur to me that I would need to instruct Vegas to carry out this change whilst rendering down.
Too much time spent with Avid!

If your video is under an hour, try changing the bitrate encoding to CBR 8,000,000 or use the Two Pass option for variable bitrate if you have more than an hour. This should allow enough bits to maintain the picture quality.

It’s important to understand what happened here. Vegas is extremely smart (unlike Avid) if you don’t lie to it. Setting the deinterlace to none is NEVER a good idea unless you are working with 100% progressive footage. If ANY of your footage is interlaced, you need to tell Vegas how you would like it to be deinterlaced should it ever need to. Vegas will take care of the fact that some of the footage is upper field first while others are lower field first. Like I said, it is very smart and knows what to do if you don’t stop it. 😉
