Does DVD Studio Pro have an 11 Gb file restriction?

Hi Everyone,

Does DVD Studio Pro have an 11 Gb file restriction?

I have finished a short film (exported in DVCPROHD1080p25). However, DVD Studio Pro won't burn this file.

A message says "data rate too high" in the log window inside DSP.

Appreciate any help or suggestions.

Thanks,
David
 
A standard, single-layer DVD can only hold so much (4.7 GB). Plus, it uses a completely different codec. You need to prep the file for DVDSP, as has been mentioned, using Compressor. Use the DVD Best Quality preset for the lowest amount of time that will fit your project. This will result in two files (one video, one audio). Use those in your DVD project.
 
First thing we need to know is how long the video is in total minutes.

That is the determinative factor, not the size of the video file.

Also, you need to encode the audio to ac3, not uncompressed aiff, which causes the message you received.

I have to disagree… using ac3 does reduce the overall nitrate compared to
uncompressed PCM, but it's only one way. The video nitrate can be lowered for the same effect. The video bitrate alone can be problematic. You have to look at both audio and video components of the overall bitrate to decide on a compression strategy.
 
I agree. The video may be encoded at too high a rate. Too often, people mistakenly believe that more is better when encoding for DVD authoring.

However, in so many cases, it's the combined rate that is the issue, so why add unnecessary overhead using uncompressed aiff audio files assuming your video is encoded no more than about 6.5 mbps for a 60 minute segment.

However, without knowing the total length of the video in minutes, we are all shooting the dark.

Re: question of length

FYI, in answer to the moderator's question, my short film is 13 minutes. It was also edited and exported at DVCPROHD1080p25.

Hope this helps!

13 minutes is nothing for DVD. However, if I'm reading your posts correctly, it looks like you're trying to author the DVCPRO HD file to DVD, and that's not going to work at all. For one, DVD is not an HD format. Second, it needs a video file that's prepped for DVD.

You need to take your DVCPRO HD file into Compressor and use one of the DVD presets (for PAL, of course). I believe the highest bitrate in the presets is in the "DVD Highest Quality 90 Minutes" option. You'll end up with separate audio and video files, which you'll then import as assets to DVDSP.
