Filesize

[weaver4]

I have encoded a movie 4 times the filesize for using AutoGK in Xvid appears to be outside the norm.

AutoGK XviD 67% (quantizer or 3) ---- 1050K
Avi.Net XviD Quantizer of 3 ---- 784K
AutoGK DivX 50% (quantizer of 4) ---- 853K
Avi.Net DivX Quantizer of 4 ---- 790K

The filesize for the AutoGK XviD is a whopping 34% larger than the same movie done with avi.net even though they use the same quantizer.

I threw in the parameters for DivX to show that the quantizer of 4 typically give the same filesize as XviD with a quantizer of 3. But with AutoGK the XviD is a whopping 23% larger than the DivX counterpart.

I have the ess option turned on. If I turn it off the filesizes get larger.

Anyone know why the AutoGK XviD is so much larger than the rest; if it is using the same quantizer shouldn't the filesize be roughly the same as avi.net?

I have seen this in another thread, but am unable to locate the specific one. :)

This may seem a bit n00bish, but have you tried to uninstall avi.net and AGK, then reinstall AGK to run the test fresh?

I encountered a similar problem about a year ago, after multiple tests, uninstall and reinstall solved the problem. (sorry don't have specific technical data as I can't find the thread)

Good Luck!

Did you make sure that both programs used exactly the same AviSynth script and Xvid setup? And I mean the whole setup not only the same quant. If the settings are not identical different file sizes are to be expected.

I reinstalled AutoGK and the filesize went down 1050K to 860K. But I have no idea why? Any ideas? Could it be because some other application installed XviD 1.1 over 1.2. Or can both reside on the same computer?

Does AutoGK check to make sure the correct version of the codec and other tools are installed before it encodes?

In order to function properly, Xvid must be uninstalled before a different version is installed in its place. No, two versions can't co-exist.

No, it will either give a bad end file or it will give an error.

So AutoGK uses beta XviD 1.2 and the rest of the conversion programs (avi.net, staxrip, fairuse, mpeg mediator, avidumux, etc) use the stable version 1.1. But when you install AutoGK it writes the Beta XviD codec over the stable version? Is that correct?

I think 1.2 has been beta for six months, seems like they should have released it by now; or AutoGK should go back to version 1.1.

You can deselect the installation of Xvid during the installation of AutoGK, or you can go back and uninstall/reinstall Xvid to the version you prefer. You're not locked into using the version of Xvid that comes bundled with AutoGK.

Just to make sure I am clear on this. AutoGK 2.40 will completely work with XviD 1.1. Is that right?

I doubt that that is true, because I found that Encodes with AutoGK and XviD 1.1 to be much larger than XviD 1.2. That is what started this thread.
