00:00:00:00 timecode
-
eric and Michael: Thank you both for voting for 00:00:00:00 not being an issue at all.
Yes, the problem comes with subtitle import. I don’t import chapter markers but make the chapters inside DVDSP, so there you have still another serious side to the problem.
For subtitle import one can import subtitles with no track present. That is also the reason why I like the 00:00:00:00 timecode – if all else fails. But it seems to be different with NTSC, so one would have to make an mpeg-file with another encoder to be able to import the subtitles correctly. But one shouldn’t have to.
I was very impressed with the Cinema Craft SP demo, and then glad to know that the MP version would make it possible for me to stay in my Mac, and that it was supposed to be even better than SP. But I find it filled with issues, and I will continue my contact with the Omni Support.

One question. Are you sure your movie file’s TC actually starts at 00:00:00;00 and not 01:00…
If you export a movie from a default FCP timeline the TC would start at 01:00… an exported movie takes on the TC of the timeline unless you have gone in and changed it.

The 00:00:00:00 timecode should not be used in Cinema Craft. It has special meaning to CCE encoder especially when you use Pulldown or inverse pulldown. This was the case with SP2 as well. I wish I could tell you why, but I have no clue. I just follow the rules. If your subtitles are off by an hour now you can use any number of free tools to adjust subtitle timecodes. Or set the start time code to 00:00:00:01.

Yes, I’m totally sure. My preset is of course changed to 00:00:00:00 as that is my favourite timecode. And I also make the timecoded mpeg1-files for the translators myself.
And… the engineers at Omni _have_ confirmed that their encoder changes the timecode, but try to make it sound like a good thing.
The only question is if anybody heard of 00:00:00:00 timecodes causing problems on DVD’s.

Interesting. So it is a Cinema Craft-problem and not a DVD-problem?
But the Cinema Craft SP-demo still allowed me to use 00:00:00:00 as timecode with no changing.

Yes you can do it in SP. They RECOMMEND you don’t. Probably something they use in their algorithm in determining the pulldown or IVTC that causes an issue with the 00:00:00:00 timecode. In MP it probably changes it automatically so you cannot run into whatever issue it is they feel might happen. I have never used that timecode before ever. No Hollywood DVD use 00:00:00:00 either. It has always been best practice to use 01:00:00:00.
The people at Omni are pretty smart. If they say don’t use 00:00:00:00 I would adjust your work flow to adhere to that warning.

Thank you. I don’t use SP at present – I just bought the MP about two months ago. I’ve mostly been using BitVice.
DVDSP’s default state is 00:00:00:00, and some difficult bugs made me adopt the 00:00:00:00 timecode, to always be able to override.
But do you agree that it is a Cinema Craft issue and not a DVD issue?
-
I think it is confined to Cinema Craft, but I don’t think it is a critical issue or bug.
-
I’m shocked Omni would do this…thats interesting. I’ve never seen or heard of issues with 00:00:00:00 TC on DVDs.

The direct answer to your question is no, a timecode starting at 00 is not, to my knowledge, violating any part of the dvd specification per se. But to elaborate on that answer I’d like to add that the use of 00:00:00:00 causes major problems in other areas of production and is pretty much banned within the video industry. There are a number of good reasons to avoid using 00 as first frame. Mainly it boils down to the fact that tapedecks and other equipment (encoders, decoders, image restoration hardware etc.) need pre-roll time to operate properly. If a program starts at 00:00:00:00 there can be no pre-roll. So that is why professionally mastered tapes never ever start at 00.
That said, what is to stop you from altering the TC to suit your specific needs? Well technically nothing as long as you stay clear of professional video equipment, apparently including CCE. However, note that it is rather good practice to keep the original TC from the mastertape throughout the dvd production, and most professionally mastered tapes would start at 01, 02 or 10 hours.
