Gknot output .avi's wierd sizes

[chipzoller]

I am following the Divx-Digest guide as it has seemed to produce better results than the Doom 9 (sorry guys).

The problem started when I was trying to burn my .avi's up to a CD and none would burn execept one. I set the filesize at 700MB and tried to burn it. The actual size on disk was about 735,500,000 or something like that. And when I have to overburn to get that. But then when I verify that the file has been written ok (using Nero v5.5.8.0) its no good. It tried copying it off and as expected, it won't copy. I re-encoded the same movies but at 697 and the size on disk was still very high, about 729,500,000 or something. I did one movie at 690MB and still couldn't be read!! My CD-RW drive is fine. My Cd's are fine. My HDD is fine. Why is Gknot making my output files so large when they are comming up 690 or so?

I"m not doing the compressibility check. Just setting the audio bitrate, 1Xvbr deal, and choosing the output size.

Whats the deal?




thanks for your help

If I understand you correctly GKnot is prefroming perfectly.
You told it to produce a 700 MB file and it does just that, correct ?
To produce smaller files just tell Gknot to do so.

If you can't burn a 700 MB file, then there must be something wrong with your burn process. Are you sure your using 700 MB media ?.

I'm not so sure that it performing correctly.

You see, 700 MB is app. 716,000,000 bytes NOT 735,000,000 bytes.

And 690 is app. 709,000,000 bytes NOT 729,000,000 bytes.

Yes, i'm using FujiFilm discs and i tried a verbatim disc all are 700 MB capacity.

In Nero's settings, I did not enable multisession, burned at 4X, finalized the disc and wrote in Disc at Once format. I enable overburn at about 76:00:00, which should be fine as the size rating of a CD is "official" although "unofficially" it will hold between 4-8 MB more.

Is there anything I can do?

I am throughly pleased with the job that Gknot is doing. It is blowing me away. However, I started this process to backup my own DVDs in the instance that one or more failed on me due to laser rot etc. I want to archive those DVDs onto CD's so that I may insert the CD instead of wearing the original DVD.


thanks,

Nope-700 MB=716,800 KB=734,003,200 bytes. Gknot's doing its job. You or your burner or your burning program aren't doing their job.

Maybe you should have gone to Georgia Tech and learned some Math. :)

Well then it must be my burning program. I must have some wierd settings.

I am using the most current version of Nero.

Can you give me a configuration that you guys burn with on Nero to get them on there correctly? I just must be doing something wrong.

thanks,

Chip,

Why are you enabling overburning?

I can burn files up to 701 MB ~ 718,664 KB(rt.click the movie..properties..size on disk). I do this in Nero without overburning. Using Nero 5.5.7.2.

This version of Nero has worked great for me so I have yet to update it.

[chipzoller]

ok well tell me the settings you use to burn.

i.e.

disc at once or track at once, finalize, multisession. etc etc.


thanks,

I use the wizard :ashamed:

I think it says something about needing to finalize the cd to which I click yes.

That should work for you too...

[chipzoller]

Ok,

Well then I think it is my burner. I tried to burn these .avi's with 2 different burning programs (Nero and CDRWIN [both most current versions]) and they both indicated a successful burn but when trying to verify the written files, the verification failed, which means that the files can be read ok on the CD if you were to open the video in a software playback program, but you wouldn't be able to copy them over to your drive.

I've just purchased another CD-RW drive, which is the best one on the market currently for copying copy protected discs etc. so this might do the trick. It is a Plextor PX-W121032A.


Thanks for everyone's help.
