I know this is the "Audio" board, but I wanted to post this here because the main page for all the boards shows that this one has a lot of users, so I figured it would maximize my chances of a good response.
I am trying to burn some episodes of a show I have onto blank DVD discs. The episodes are 20 minutes each. The discs are 120-minute discs. I want to fit 8 episodes onto one disc. 6 episodes are 120 minutes. But because I want to fit 8, that runs me to 180 minutes.
I hear there is a way I can set DVD burning software in such a way that it will allow me to fit more than 120 minutes worth of video onto a 120-minute blank DVD disc.
Will 40 more minutes make that big a difference if I fit two extra episodes onto the disc? To paraphrase will two extra episodes really run the video quality down much if I "cram" them on there? It's a cartoon, incidentally
Any help is appreciated. -

A few notes:
- Your question has nothing to do with "Audio Equipment and Home Theater Audio". I suggest posting in the "Computers and Software" section.
- A user account lets you post anywhere on the IMDb forums. Posting to a topic where there are more user names will not get you more views, especially if it's off-topic in the area where you posted it. Granted there are some people here who haven't figured out that there's a main menu, but would you take advice from someone like that?
- While time and space may be interchangeable when discussing theoretical physics, it's a
non sequitur
when it comes to blank DVD discs. There are single layer discs and double layer discs; they both occupy the same space, but the DL type hold roughly twice as many
bits
, which is the quantity that matters most here. I did find an old spindle of CompUSA DVD+R discs that were labeled "120 min", right under "4.7GB". The "120" is a somewhat arbitrary number when dealing with lossy compression.
You could either increase the lossy compression (at the expense of video quality) to make all 8 episodes fit onto a single, 4.7GB "DVD-5" disc, or buy a similar sized but greater capacity disc such as DVD-9. I'm presuming that you've already edited out any commercials, as each episode is only 20 minutes long.

Yes. You do this in the MPEG ENCODING step, BEFORE burning the disc. If your DVD authoring software allows this, set the bit-rate of the video signal lower than the normal 4000 kbps for 2 hours, like 3000 kbps. The visual quality will be horrendous, but that's the trade-off with compression. Or you could encode the video not as a DVD but as a video CD.
Use Dolby Digital or MPEG Layer 2 audio as an audio encoding option, as these use much less space than PCM.
