No bottom field in procoder menu

[tamaronvideo]

After completing a project in edius, I am using the included procoder for DVD output. Since upgrading to 4.6 I do not have the option of selecting bottom field for output. When using the drop down menu in advanced options, only upper field is available to choose. All other options seem to be there. I am seeing noticable flicker on burned DVD's with this setting. Any suggestions? Thanks. Joe

Try export to canopus HQ, then use procoder to do the dvd transcoding using upper field.
It works

So did somthing change in 4.6? We are getting ready to upgrade.
Maybe we don't need to?

Choose Generic ISO MPEG stream under Stream Format.

This change did bring up the bottom field first as an option. Thanks. Any idea as to why it is not there when using DVD elementary stream as an option? Is there any quality difference making the change? Thanks. Joe

yes, it is incorrect to use lower field for DVD, this is why the option was disabled so users can't make a mistake

check any Hollywood DVD, they are all upper field

don't worry about the field order of the source, even if the source is lower, the destination can be upper and there will be no flicker

That is right.

What if you have been working entirely in 29.97 PROGRESSIVE? Is it ok to choose progressive output for DVD? Especially if you intend to display on a progressive device with progressive playback device? Or does the DVD spec demand it be encoded as interlaced?

Thanks,
Tim

the DVD spec says interlaced, however Blu Ray allows for progressive

progressive may work with standard DVD but I am almost sure it may produce some flickervision for the user?

DVD supports 3:2 24p (23.976p) pulldown, but only on NTSC.

There's only one way to find out. :)

I'll let you know my results. I'll try it on a number of different displays as well.

Anton:

You are unequivocally correct, sir. (As usual, lol.) Encoding as progressive does not appear to create flickering, however it creates a lot of "jaggies." Once things were encoded to upper-field first, everything looked as smooth as silk.

Seems a shame to take perfectly good progressive video (through-n-through), interlace it, send it through the DVD and de-interlace it ... but that's the way it goes. I suppose when the DVD spec was written, progressive displays were definitely not the norm. (I got my first DVD player in early 1997 and was amazed showing it on my 32" tube Triniton. My how things have changed.)

It certainly doesn't hurt to keep all of your video (or as much as possible) as progressive until the final encode though.
