[Dogfather] “The work flow to make a DVD is as follows, I export my Timeline out to a DV pal 48k as a reference file then drop that into my idvd project and burn.”
I had to deal with this myself when I started using P-JPEG. The only way you can make this work is to use Compressor to create your MPEG files – and you have to export to Compressor directly from FCP. Exporting a reference or self-contained file first will not work.
When you export to Compressor directly from FCP, FCP will tell it what the correct field dominance is. Unfortunately, there is no other alternative.
The reason this is screwed up, I think, is because either Final Cut or Blackmagic requires NTSC video to be lower-field first (I’m in NTSC-land, the oppisite may be the case for PAL). So it captures and edits P-JPEG as lower-field first. However, according to Quicktime, P-JPEG is supposed to be an upper-field first codec and will interpret it as such if it doesn’t know any better.
DVDs (in NTSC) are upper-filed first. So even thought it should, iDVD will not reverse the fields of Photo-JPEG because it thinks it is also upper-first.
The only way for the QT app to know what the field dominance should be is if Final Cut is directly communicating with it. That is why exporting directly to Compressor works just fine.

[Michael Lynch] “IMHO it’s a sad, sad oversight on the part of Apple”
This was not an oversight. Believe me, it was a calculated decision.

Motion comes with some smoke particles.

I don’t speak German so I don’t know what nico just said, but your best solution would be a Multibridge. This will give you 8 channels analog output. You simply set up the audio tracks in your Final Cut sequence to achieve what you want.

Daniel, I understand you think the new sequence settings matches the settings of the reconnected clips. It does not. If it did, you would not have to render. It’s that simple.
I’m fairly certain that your clips have Motion attributes applied to them because they were altered to match the frame size for your offline P-JPEG work.
You need to open up one of the clips and go into the Motion tab. Make sure scale, center, and anchor point are set to zero. Now click the triangle next to “Distort”. Make sure “Aspect Ratio” is set to zero as well.
If any of these are not zero, you need to select all of the clips in the sequence, ctrl-click, and select “Remove Attributes”. Then check the appropriate boxes.

[RitaKSanders] “Or will I have to reverse telecine each of my 1500 clips individualy with the correct field choosen”
As far as I know, you have to do it this way. Doing a batch assumes the A frame is on TC 00. I’d consider going to a place that has a Teranex.

I’m not so sure the Decklink has a built in limiter. It could be the codec that causes the clipping. You might try testing different codecs in the capture settings (try Apple and BMD codecs). Or try the Decklink Capture Utility as well as the NLE capture.
In Final Cut, I remember having a lot of trouble taking a 4:1:1 DV source and render it to Uncompressed without it legalizing it automatically (even if though the sequence was set to “Super-White”). So I suspect it’s the codec and not the card. Just a hunch though, I have no way of testing your situation myself so I could be completely wrong. Hopefully someone from BMD can chime in on this.

[Lili Lab] “‘m sorry, I wasn’t clear – I meant putting it from a Blackmagic 8 bit Uncompressed 1920 X 1080 sequence to a DVCpro HD sequence then compressing it to DVD… I heard the DVCpro Codec is much closer to native SD than the HDCAM 8 bit uncompressed directly to SD. Is this true?”
I assure you that you heard wrong. Two things:
1) Converting it to DVCPro first will degrade your DVD’s picture quality, not improve it. I don’t know who told you this was a good idea, because it isn’t. You’re being fed bad information based on voodoo science and supersitition. Yes, DVCProHD and widescreen DVDs do have something in common, they both cheat 16:9 by using anamorphic 4:3 resolutions. But this means absolutely nothing in regards to what we’re talking about. It’s about as significant as the fact that both formats start with the letter “D”. If you do this, it will add an additional level of lossy compression to the workflow. The DVD will look worse, I promise.
2) Even if you did render it on a DVCPro HD timeline, Compressor and Final Cut will reference the original media. So what you’re proposing would not accomplish what you want to (but shouldn’t want to) do.

I know a couple of videographers who are very smart, yet very ignorant on this subject. I think when you invest a lot of money into a camera, it’s hard to accept how inferior it is compared to HD video.

It can be done. There are Easy Setups for it (“Blackmagic NTSC 23.98hz – 10 bit” is one of them). It will only work if the cadance does not change and if it is correctly matched up with the VITC timecode (the A frame falls on 00 frames, I think). A properly mastered feature should be fine.
Keep in mind, if you do this, you cannot batch re-capture selected clips via Media Manager later on. So take in everything at full quality before you start editing.
