700MB avi to DVD compliant

[Intuit]

Hello all. WEll I thought I had this whole AVI to MPEG2 thing figured out, but apparently not anymore. I recently am running into problems I never remember having before. I have always been able to take a 700 mb avi, encode it and end up with a movie that is less than 4.4 gb. Now, when I encode I end up with a 6gb file. I can't figure out why. I am doing everything the same as before I think. I use Canopus Procoder 2. I set my bitrate to CBR 8000 and audio as mpeg2 audio. My quality is set to mastering. Anyone know the correct settings to get a 700 mb avi file on to a DVD to keep the best quality? Thanks!\


Oops, update, my file was XVID not AVI...

The size of your AVI file is immaterial. It's the running time that matters. For your output MPEG file:

file size = running time * bitrate

Use a bitrate calculator to determine what MPEG bitrate to use:

My run time is 1:45 or so. Whenever I try and go to the bitrate calc, my ie closes???

I come up with an average bitrate of 5750 or so for an hour and 45 minute movie (that's what you meant, right, and not a minute 45 seconds?) with an audio bitrate of 192. Of course you're going over setting it for 8000 CBR. You should be using VBR encoding anyway.

Use a different bitrate calc then, if you have trouble getting to the Videohelp.com one. I use GKnot's one.

Yea, I went through another guide for TMPGENC and came up with 5250 as well. But I still can't figure otu why IE closes everytime I try to goto the bitrate calc.

My source video is 1 hr 45 minutes.

If my source video's audio is only 136 kb, does it do any good to set it higher when encoding?

Hi-

Getting it sorted out now, eh?

If my source video's audio is only 136 kb, does it do any good to set it higher when encoding?

I don't use anything less than AC3@192 for stereo tracks. Up to you. You're right though, that the audio quality's not going to improve by using a higher bitrate.

[Intuit]

Yes, slowly but surely. Thanks for your help Manono. Which AGK package do I DL? The one thats the codec pack or the one for ripping?

[Intuit]

one last thing, what is the min bitrate to maintain a good quality DVD assuming the DVD is not over 2 hours long
?

[manono]

You'll want the Gordian Knot Rip Pack if you only intend to use it as a bitrate calculator.

The usual advice is that for DVD you use 3-4 times the bitrate of the AVI source. To find that AVI bitrate, open it in GSpot.

Thanks alot for your help. I learned a bunch. Hopefully now I will be able to get these new scifi vids off my cpu so I can watch them on the TV!!!

[manono]

You're welcome, and it was jagabo that gave you the most important bit of information in the whole thread.

[Intuit]

Your right, he definitely helped as well. Thank you as well Jagobo!!!

[jagabo]

You're welcome Intuit. Sorry I missed out on the rest of the conversation.

By the way, if you still can't get the online version of VideoHelp's calulator running, you can try downloading the version that runs locally:

If that doesn't work there are others:

.......... But I still can't figure otu why IE closes everytime I try to goto the bitrate calc.

You have a BHO (browser helper object) not helping. Very possible it is the "Yahoo" toolbar. Remove it and/or any other tool bars.

[Intuit]

Thanks Jagobo and Holistic. Unfortunately I don't have the Yahoo Toolbar or any other toolbar installed....any ideas for anything else to try?

For now I will jsut download the local calc, but it would nice to fix this browser problem...

I do have Java installed btw. Thanks again.

[jagabo]

The link I gave earlier leads to several bitrate calculators you can check out.

The problem with VideoHelp's online calculator is probably Java related. You might try upgrading to the latest Java engine from Sun.

[Intuit]

Right on. Thanks! Funny thing is, the vidhelp calc worked after i UNinstalled JRE and Sun!!!!
