reverse fields when making DVD
I have FCP 4.5, I am working in PAL, I have made a Photo-jpeg timeline, I have captured some footage from beta SP YUV using the photo-jpeg capture setting, I have also captured some DVD footage from composite input of my Deck-link Extreme card using the same capture codec, all’s fine when I edit and play back, I do know that Pal DVD footage is Lower field, but if I have captured this material using photo jpeg does this mean the codec has correct the material on input when I captured it.
When I go to burn a DVD, on the sequences that have been captured on DVD it’s jerky and it look like its in reverse field dominance also on some of the beta slow mo sections this happens too.
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.
As I have read this is the way to make DVD from FCP. -

PAL DVD supports both: lower AND upper field first ! I had this problem once too and it was a question of getting the right settings when encoding it with compressor. I don’t know about iDVD.
But you can export your Decklink Timeline to compressor and the result is a upper field mpeg2 stream, and this works well!. Maybe you have to make a special compressior setting to force encoding it with upper field. -
Hi Noe,
iDVD is a consumer product and requires a linear video stream. This means that you cannot drop mpeg files in to it. This contrasts to DVD Studio Pro which does allow you to add mpeg files in to a DVD Studio Pro project.
The Help for iDVD recommends exporting movies from the source program in to DV NTSC or DV PAL QuickTime movies.
I haven’t used DVD Studio Pro a lot but I was very impressed by its ability to create High Definition DVD’s using the H.264 codec. It did take a long while but the results were stunning. DVD Studio Pro is definitely capable of producing higher quality DVD’s than iDVD but I’ve also found iDVD to be surprisingly good when in a rush.

Thanks for the advice I’ll use compressor for the DVD.

Hi,
It would be great to know if that makes any difference. In theory what you’ve already tried should work well. However Compressor is more powerful than a simple QuickTime export so hopefully it will help. Please let us know how you go.

Yes
I’ve had this problem as well in NTSC. Sending BM NTSC 10 or 8 bit files to IDVD. I think IDVD does not play nicely with 720 x 486 files. It prefers 480 in DV codec. I’m guessing it it gets confused with the 6 extra lines. This is too bad – it kind of kills 8 or 10 bit picture quality if you have to compress to a DV codec movie prior to exporting to IDVD. Even though IDVD is a consumer app, its so convenient at times to use for quick roughcut outputs for client screener DVD’s. For me, in many cases dumbing down to DVCodec and Meg2 on top of that is not too great for the client reviews.anyone else experience this? – any other work arouunds besides the Compresser to DVDSP or DVcodec to IDVD route?
