90 minutes of HQ mpeg on DVD possible? at DVinfo.net

Darryn Carroll · August 25th, 2010, 07:20 AM

Hello all, I am learning (slowly I am afraid) and doing a lot of trial and error which leads to my question today. Can I get 80-90 minutes of HQ mpeg (DVD quality) footage on a single layer DVD? When I render to SP mpeg and burn, I can see the difference between that and a HQ mpeg burned to a DL disc.

Thanks all.

I too am going through that same learning process.

Going from HD to SD is all about how the transcoding is done.

I start with Panasonic 60p, import into Edius Neo Booster, export as AVI, import into TMPGEnc, export out as .mp2 and .m2v files.

Then you have to create the DVD files/folders, then burn to DVD.

Yes, it is ridiculous how many steps it takes to do this.

Even though I am struggling with the audio portion of my DVD creation, the video portion looks excellent.

Others on this forum suggested all the software I am using.

Now to your question of will it fit?

I'm sure you can make it fit, how it might look is a different story.

From what I have read, most people say 60-80 minutes is the maximum you should shoot for.

Thanks Alan,
I think I need to try my hardest to get these finished projects down to 60 minutes!

Darryn, check out this bitrate calculator:

Bitrate Calculator

You can see that at 90 minutes, you can still encode at about 6500 kbit/s with audio at 256. This should give a pretty good result if you use multipass variable bitrate encoding.

I usually see 90 minutes as about being the limit, however. Past that, your bitrate starts to drop alarmingly. For example, at 1 hour 45, you're down to about 5500. The sweet spot is about 80 minutes, where you are over 7000, approaching the max of what you would want to use anyway.
