Field dominance issues

#42 – Quick and dirty way to author a DVD

Shane’s Stock Answer #42 – David Roth Weiss’ Secret Quick and Dirty Way to Author a DVD:

The absolute simplest way to make a DVD using FCP and DVDSP is as follows:

1. Export a QT movie, either a reference file or self contained using current settings.

2. Open DVDSP, select the “graphical” tab and you will see two little monitors, one blue, one green.

3. Select the left blue one and hit delete.

4. Now, select the green one, right click on it amd select the top option “first play”.

5. Now drag your QT from the broswer and drop it on top of the green monitor.

6. Now, for a DVD from an HD source, look to the right side and select the “general tab” in the track editor, and see the Display Mode, and select “16:9 pan-scan.”

7. Hit the little black and yellow burn icon at the top of the page and put a a DVD in when prompted. DVDSP will encode and burn your new DVD.

THATS ALL!!!

NOW…if you want a GOOD LOOKING DVD, instead of taking your REF movie into DVD SP, instead take it into Compressor and choose the BEST QUALITY ENCODE (2 pass VBR) that matches your show timing. Then take THAT result into DVD SP and follow the rest of the steps. Except you can choose “16:9 LETTERBOX” instead of PAN & SCAN if you want to see the entire image. This is what I do for my DVCPRO HD projects to get them onto DVD…and I have no field issues whatsoever.

Thanks Shane for the response. I’ve been doing what you suggested and at that stage (DVD) the image looks terrible.

I think you are suggesting that this is not a field issue and that FCP, Compressor and/or DVDSP are managing the field orders irregardless of how the clips were captured. (?)

If that is the case it goes back to what I had first suspected which is that the brighter scenes are causing Compressor to degrade the image. I tried applying the broadcast safe filter which didn’t seem to help either. Any ideas?

thanks,td

Let me guess, this is in FCP6, correct? THat shift fields thing is a bug and annoying as all get out.

720p is progressive, are you sure you have your sequence setup properly? There’s no way it should have captured with fields. What frame rate are you working in?

You should make a DVD from the HD material, and not render down an SD timeline. If you are working @ 23.98, keep the DVD @ 23.98 and make sure you tell compressor that your footage is progressive 23.98 and to keep it that way.

You have an interlacing mess. Yous should start checking the field order of your footage. You can do it in Shake or in AE.
Another matter is, don;t let Compressor guess the field order of your movie. Set it manually in the “Video Format” tab of the compressor. Compressor expect always the DV movies to be lower-first, but this is not always like that. If you feed Compressor with a Dv movie upper-first, Compressor will set the wrong field order, unless you tell him the correct one. In DVDSTP you have not the chance of setting the proper field order.
