Thank you very much that clears up a lot, but I still have one other question on a different note. I realized that the field order in Encore is always going to be lower which SD video usually is. I have also heard that if you bring in a video that is upper into Encore, Encore will automatically transcode it to lower and you will lose a lot of quality. If my film is progressive video and I'm converting it from HD to SD in apple's compressor should I just leave the field order as "none (progressive)" or should I make it lower?
I read somwhere that if a song was created pre-1970s then you do not have license it, is this true? I can't remember where I read it.
You must have the permission from the author to use any music.
In the UK, the duration of copyright for musical works last 70 years from the end of the calendar year in which the author dies. Copyright is comonly held by many authors; music, lyrics, producers, performers distrubution comanies to name a few.
I implore you to check the law in your own country as a producer, you have a deplorable lack of understanding of copyright.
For what it's worth...
You also need releases from all your actors, agreeing for you to use their sound/image.
You also likely need releases from the owners of the locations you film in, and/or permits if filming in public places...
And contracts for the crew, I imagine in this case, stating that they volunteered their time, or will be paid should the film happen to make money.
These are the types of things that will stop someone from taking your film global, should they see one of your self-published DVDs.
As the topic of this thread has bounced around, I noticed that no one seems to have addressed your field rendering order question.
If you want the DVD-Video content that you've authored to be to DVD specifications (which, well, you _should_ want this), then you need to conform your video stream (the MPEG2) to either NTSC or PAL standards. So, to comply with NTSC MPEG2, your video stream would need to be 720x480 lower field first. Your edited 24p master should go through 3-2 pulldown so that it's running at 60i. I allow for three files in my workflow: the 1080p24 HD master (usually Apple ProRes 422), then the 480i60 master (usually Apple ProRes 422, but sometimes DV-NTSC) and then the the MPEG2 480i60 encode.
On a side note, not all SD video is lower field first. D1-PAL, for example, is upper field first. Also, it's common to find older analog to digital transfers (VHS, Hi8, 3/4", and Beta to Radius VideoVision, Targe2000, or Avid AVR) to be upper field first.
