Johan,
This can be done pretty easily, since you are dealing with the same frame rate. The best way would be to take it to a dvd authoring house and have it encoded with a high-end hardware encoder (ie. Sonic, Digital-Rapids, etc.) However you can simply use compressor to encode the DVCPro to mpeg2 for dvd. You may want to search the archives of the DVD authoring, Sonic and DVD Studio Pro forums. There is a lot of info there that can probably get you going in the right direction. Hope this helps.
Best Regards,

What is the frame rate of the DVCPro?

[Walter Biscardi] – “Graeme Nattress’ filter is only for SD.”
This is not true. You can use the Nattress filter for HD frame rate conversions, which is why there are HD resolutions under the “source pixel size” option of the plug-in. We have gotten very pleasing results converting 1080 HDCAM material from 25 to 29.97 using the the G-converter filter on two different features that we did. Granted, the best and fastest way to do this is with a Terranex, but Graeme’s plug-in works extremely well when going from PAL to NTSC frame rates. We have not had as good of success using it to go from 29.97 to 25, but this was coming from 23.98 material with a pull-down added. We have not tested it out with HD material actually shot at 29.97. Shake does a pretty good job converting HD material from 29.97 to 25, but it takes forever and is still not nearly as good as a Terranex conversion. It may be different for HDV material, but for the Nattress filter does work well with 25 to 29.97 HDCAM material.

“my aspect ratio changes to 720 x 480”
If you are endcoding an SD dvd from an HD 16:9 source, then this is correct. You are basically creating an anamorphic 4:3 version, which when played back, will be anamorphically squeezed down to display 16:9. This gives you a much better picture then simply letter-boxing 16:9 to 4:3.
“And what’s the scoop on the HD DVD settings?”
These settings are for creating HD DVD’s, you can encode to these settings and put them on a regular dvd-r, but you will only be able to play the material from that dvd-r on a computer that is fast enough to handle the playback of those files, in this case you are simply using the dvd-r as a type of media to store files on, it will not function like a regular dvd, so a regular dvd player will not be able to play it. These settings are for creating HD DVD’s or Blue-Ray DVD’s, which are an entirely different type of media and have compleatly different specs then regular DVD’s. They require a different burner, different player and different disc format.

“The test I’ve done in the past created duplicated frames”
You most likely got duplicated frames because your settings were probably set to encode at 29.97. If you are encoding from a 23.98 source, then you want to make a 23.98 mpeg for your NTSC dvd. It’s written into the DVD specs that all dvd players and decoders will add 3:2 pull-down to 23.98 mpegs, for ntsc playback at 29.97. Do a search in the DVD studio pro manual for 23.98.

Hey Mike,
You can download the AJA quicktime codecs for both Mac and PC here

Walter,
I’ve been using the plug-in version on a quad G5 to grade 1080p material and I have had no problems. While it is not Final Touch and definately not Speed Grade, I think it’s light years beyond the FCP 3-way corrector. I’ve created a coloring window setup to give me previous and next shot previews and it’s been working very well. My biggest complaint would be having to refresh the monitor out when stepping out of the UI, but I’ve simply programed a button on my wacom tablet, so I just hit it after stepping out of the UI. All in all, I can still move very fast and grade quickly with this setup, for the money, the plug-in is a great add-on. Just my 2 cents.
best regards,

Mark,
If quicktimes are no problem, then simply edit in HD at 24p and export sd resolution quicktimes. We give our audio department 24p photo jpeg at %75 quicktimes and it works great for them. They have a good looking sd resolution version at 24p and file sizes are not to large.
best regards,

Mark,
Is your final delivery 25 or are you just needing 25 dubs for audio and other areas of your workflow? Because there are a couple of different ways to approach this depending on a few parameters. Some options are obviously more expensive then others and some have benefits that other options don’t. Will you be going out to film, HD, SD or straight to DVD?

Walter,
Congratulations! Was this a project that you finished uncompressed, or was it DVCPro? Just curious, because I know you do a lot of DVCPro work.
