hdv to dvd, interlaced or de-interlace
I'm using FCP 6.0.5, Compressor 3, editing 1080i HDV captured as prores and exported to Quicktime movie as prores. Then, to compressor using default High Quality 90 min DVD settings, then to DVDSP. The DVD looks bad and with a ton of interlacing lines. Where am I going wrong and how do I get the interlacing issues solved?

You could try setting the field dominance to none in your sequence settings. The usual default is 'upper odd' for HD.
After opening your sequence go to Sequence/settings then click field dominance, click none then OK. You will need to render out your time line and export the self contained movie ready for compressor. it works successfully for me when I'm downscaling from HD to DVD. When you set it to none for field dominance, in theory FCP acts as though it's a progressive video and not interlace, so whatever the theory is, it works and gets rid of the jagged lines. another thing you could try when in compressor, is to use frame controls, this usually helps. |

Yeah, frame controls (set to deinterlace) really help the quality, but it also increases the length of time it takes to compress.

I noticed the default for Compressor's DVD setting was already set to deinterlace in frame controls. And thats when I got the lines. I tried setting the frame controls off, but it would say "failed".
I ran into Ken Stone's tutorial to export HDV to Quicktime Conversion, left the deinterlace un-checked, and it worked great. Even the jagged text was sharper. I also read threads saying not to use "quicktime conversion", but only quicktime - but so far this was the best method. I will also try setting the field dominance to none as Anthony suggested. Thanks for the replies all. |

Here is another method that someone blindly says it works great, but not tried this myself.
It's named the The Bonsai Method Step-by-Step |

I use compressor to do this via Frame controls - make sure that the output field is set to Progressive or it does nothing! And use the best setting for deinterlace. It takes forever though to process (I mean many hours).
Mind you no matter what method you use it is never perfect leaving some interlacing artifacts and will compromise the image quality a bit (softens it). Also recently I've noticed that certain DVD players do a very good job of dealing with interlaced footage (no artifacts and very sharp image) making it pointless doing it. It's a lottery though as some don't. If you print back to tape and view it from that medium deinterlacing is also unnecessary. |

Hi Pavel, if you have FCP 7. Or anyone else who uses FCP 7 (Version 7 seems to have a continued issue when downscaling from HD for DVD production with jagged edges).
Apple suggested to me after discussions about the jagged lines issue. They suggested as a work around, to set the settings in FCP to 'None' field dominance. And when ready to export, go to file/share. A dialog box appears, you have a selection of various devices, such as Apple TV, DVD, iPod, iPhone, mobileme and youtube. Select DVD and then choose your filename and your destination location, then in the bottom left of dialog box click on 'send to compressor'. Or if you so desire click on Export, this will simply create a m2v file for DVD production. If you click on 'send to compressor', compressor opens, just simply accept the default settings and click 'submit'. I have tried this a few times now and jagged edges have almost practically disappeared. |

Hi Anthony and Geoffrey
Thanks for your input, I was shocked to see the crazy lines. When I did a test with Upper field in FCP and interlaced in Compressor the output was unusable. This is a big issue in my view.
Definitely I went with field dominance set to None in FCP and Progressive scan in Compressor. Tip for Compressor : MPEG2 down conversion will soften your image. I used Sharpen edges in the Filter Pane and experimented with the settings (the setting will vary depending on your source footage) and it did improve the overall image. Also the latest update apparently fixes some issues with downscaling when using frame controls according to Apple. I am quite happy with the pictures now on computer screen. Did you see your "progressive" work on television yet? Thanks you. Regards, Pavel

Dont forget that you may need to change fields if going to SD DVD as SD is lower field or if you edit in a SD Seq the HD footage with need to have a shift fields filter on the footage.

Hi Simon, excuse my ignorance but can't a SD DVD stay Progressive if the source footage was progressive (25f)?
Thanks.
