DVD Studio pro won't go 24p

I have been trying to burn this dvd forever. I export my 24p timeline FCP movie using compressor, also set at 24p. I open the .m2v movie in quicktime and it says fps of 23.976, but when I import the asset into Dvd studio Pro, it says it's 29.97. When I burn a dvd of this it's obviously wrong.

What am i missing here?

Thanks for any help.

First of all, anything that is "Burn" to DVD is going to be 30fps (29.97). DVD's are not met to play-back 24p. That's if you're burning as a "DVD" with a menu and etc. As I read above, it seems thats what you're trying to do. Anything that you burn to DVD, you should use compressor: here are standard rules.

1.) If the project is under 90 minutes which it probably is, go ahead and select the folder for DVD 90 minutes (Best Quality). You should be able to select two files:
- .m2v (Media) and ac3 (audio).
Then select a directory of where you want to store the final export.

2.) after that, go ahead and open DVDSP and import your assists. You should be good from there.

Never export anything at 24p for a DVD. You can shoot 24, but you can't burn it as a DVD that would be played on a stand alone dvd player. Anything that is digital (DVD), will play back at 29.97....period.

good luck.

Hi Murray,

No offense, but you are wrong. DVD's can indeed be 24p and DVD SP does work with outputted 24p footage.

http://en.wikipedia.org/wiki/24p#24p_on_DVD

My understanding the reason DVDSP shows up as 29.97 is that it is including pulldown flags to the DVD player and to be 'compatible' with NTSC standards; a progressive DVD player will automatically disgard this added pulldown and will display 24p properly.

If Compressor output your 24p (23.98), and the good thing is Compressor naitively knows the frame rate of the source, then you're project going into DVDSP will be 24p. Some more info:

You can also google more info about 24p DVD's. I know some compression tools require a specific step to include pulldown info, but I'm not sure which ones do.

I was basing my knowledge off the NSTC standards. Any boardcast information is always 29.97.

Since a 24p DVD allows me to use 30% less compression, I will disagree that it makes no difference, and that clients are not able to tell.

But, you do what makes you happy. You might want to call up the Hollywood studios though and tell them to stop using 24p DVDs. We just want to be entertained.
 
I found the solution to this and thought I'd post if others have the same problem.

I was exporting my FCP project directly to compressor. WRONG way to do it.

This is what I do now and it works great-


1. Export FCP project to quicktime movie using current sequence settings
2. Drag the exported file into compressor and use the compression that best suits the project (90-min...) making sure the frame rate is either "automatic" or correct for your frame rate. *
3. drag the M2V File and audio track into DVD Studio pro. The inspector will still say 29.97, but it is a bug. It will be a 24p dvd.

* I initially had problems with this and it would say "could not open source media" or some such. A little googling later and I found out it was a Quicktime version issue. Once I reverted to an older version, (7.3 I think) it worked like a charm.

I was having a similar issue, where DVDpro is showing the imported clips as 29.97, when I know in FCP they are 23.98. I noticed this when some of my clips where jumping/cuttting off early. I checked the edited footage in FCP, everything was fine. That's when I checked the settings in FCP and noticed it was compressing with H.264, which the DVDpro book specifically says might cause issues because it only samples like every 15 frames or something like that, so I changed it to dv/dvcpro-ntsc. Problem is, when I do that there is no setting for 23.98, or even 24. There are frame sample rates or something like that, I read somewhere you have to use a multiple of 24, such as 12, 8, or 4. Should I set that at 12, could that be what is causing the problem? I know it is definately NOT the source footage, everything points to the export/compression method, since I assume DVDpro4 only imports whatever the file is already set up as. What is the best sample rate to use? What key frame?
Also-every time i change these settings, and go back, they always revert to the original (H.264) settings, so I have to change them every time, which is very annoying. There does not seem to be a "set as default" or "revert to original settings" button which really sucks!

I'm digging up an old thread here, but I am still having the same problem. I have exported my video as a custom m2v (it's only 20 minutes so I upped the bitrate) in compressor at 23.98fps and DVDSP won't let me import.

Is this roundabout, QT method still the best way to rectify this problem?

I'd prefer to stay in 24p, obviously...

I still use the method I mentioned, but no longer consider it to be a 'roundabout' method because you make your master file, then make the m2v from that.

It sounds like you might have gone too high on the bitrate and that's why DVDSP won't let you import. ??? Just a guess. Try a lower one and you'll know. I don't use anything over the '90 min best quality' setting, which is safe for most dvd players to handle.
 
Maybe you are right about the bitrate...

I'll let you know... I am currently compressing the "master file" with the same bitrate as before. So, we'll see if it works. I just want to use up as much space as i can on the DVD... no point wasting it!

And, you do make it sound less "roundabout" the way you describe it.

Thanks

The DVD specification has a maximum bit rate. You can't just use anything you want. I believe 9.8 Mb/s is the upper limit and that is Video and audio combined. So to stay safe, don't specific anything more than 8.5 Mb/s for your video stream. Or you could use a bitrate calculator like this one:

http://dvd-hq.info/bitrate_calculator.php

So you don't have to rely on silly sliders with vague options like "good" or "best".
 
Yeah, I think it's really handy to have a master file (uncompressed or prores) of your movie, because then you can make other versions (web, projection, send to tape etc..) without needing to open up a fcp project that might have missing media.
 
great points...

and, perrone, you are correct...

I ended up just using "best quality 90 min" and it worked.

thanks guys!

(it also seems to go much faster working off the "master movie file" rather than from the sequence!)
