376 minutes in a DVD?
on Sep 2, 2009 at 4:12:53 pm

Hello,
I have to make a DVD from 376 minutes of video.

Is it possible?
I'm working on MacOs X, what's the best program to compress?
I have Apple Compressor, is it good?
What settings have I to set?

Thanks
Greg

[Gregorio Pellegrino] "Is it possible? "

Sure, but quality will not exist.

[Gregorio Pellegrino] "I have Apple Compressor, is it good? "

Compressor is great but no compression software in the world is going to do what you're asking and be able to deliver a decent image quality at the original frame size.

[Gregorio Pellegrino] "What settings have I to set?"

If you had no menus (gfx, pics, etc) you might be able to get away with a bit rate of up to 1600 Kbps for video. This will leave a little (very little) room for audio.

If you're doing this for a client I'd dig a little deeper. You may find that they're needs and expectations don't mesh.

Good luck.

Yes I know that there will not be quality, but it is the video of a lesson, really static.

The problem is that in Compressor the bit rate is in Mb/s and the minimum possible is 2.0 Mb/s.

Thanks for your help,
Greg

Ah yes, you'll need to get Episode from Telestream to go to a lower bitrate.

You could use compressor and you'd get watchable quality (depending on your source format) but only if you used a Dual-layer DVD

Ok, but I don't know if every DVD player could read a duble layer cd...

All DVD players support dual layer discs.

Ok, I'll make a DVD DL. But I have another problem, the smallest bitrate in Apple Compressor is 2,0 Mb/s that compress 175 minutes for layer, so for two layers 350 minutes; but I have 376 minutes, how can I do?

Thanks for your help
Greg

Like I said, you'll need to use another application to get a lower bitrate, and I recommend Episode

Is there an application cheaper then Episode, or free?

Thanks,

There are two free encoders that can create compliant mpeg2 dvd streams

http://mjpeg.sourceforge.net/

http://ffmpeg.org/

Both will allow really low bitrates. At really low bitrates rescaling to 352x480 half-D1 frames can reduce compression artifacts and increase quality.

What bitrate calculator do you suggest to me?

You can do this.
If you use a DL DVD+R, your bitrate will be 2.7 for the video only, assuming you use a Dolby AC3 stereo track for audio.
This will look pretty bad in Compressor because it has a max of 2 passes. Using something that will do more passes will give you more opportunity to save some quality. I'd suggest Cinemacraft's CCE-MP encoder which works as a plug in to Compressor. It's $800 and does a good job, but I've never gone as low as 2.7 with it. 3.5 looked pretty good and that was fast action stuff with a lot of detail whipping by with camera pans and quick edits.
Keep in mind too that some DVD players may have trouble playing back a burned DVD-9, so your other option is to make this a set of DVDs and split the program over two or more discs.
