need help with DVD to DivX encoding with GKnot...

[9inchNAIL]

When I encode movies (I own) with Gordian Knot to play on my HD
they are usually of fairly decent quality, but many
movies use'divxmpg4ver3' instead of the regular 'divx codec'
video compression you get in the GordianKnot download
package, and it seems to give a much better quality with less
picture noise.

Would I have to buy or download another dvd to divx program which features this video compression, or is it possible to download it as a plug-in and use it in GK? And if so, does anyone know how?

I hope someone can help, and at least has a vague idea of
what i'm on about,not entirely sure if I do..(!)
Thanks

This was your first post to Doom9's forum. Welcome.

As best I can recall, "divxmpg4v3" is an older name for what is now known as DivX 3, and is one of the codecs you can encode with via Gordian Knot. DivX 3 was based on Microsofts old MPEG-4v3 codec from the late '90s.

However, on your first post, it appears you are in violation of Rule #6 (http://forum.doom9.org/forum-rules.htm), since you are apparently asking about movies that you do not own. Rule 6 is one of our most important rules. You may have missed, or misread, this announcement (http://forum.doom9.org/announcement.php?s=&forumid=6). Please review it, and the rules. Thank you.

Thanks for the reply, although I have to say I wasn't intentionally referring to movies I do not own. I'm pretty sure that there are movie trailers which are free to download from official movie websites, which Im sure was how I found out about that particular divx codec (mpg4v3), which seems to give a higher quality divx encoded movie overall than with the codec you get with GK.

I'd like to at least know how I could get a better quality output of movie overall, encoding with the divx video codec you get with the GK pack gives a fairly decent output, but I'd like to know how I could get the best quality encoded movie and get rid of some of the noise that still seems to appear in the picture.

I like to watch movies (that I own already!) on my hard-drive to save the trouble of taking them out of the box all the time, and Ive got a rather large HD anyway and its always nice to be able to find a use for it. If you can (legally) download other DVD to divx video codecs to use in GK for a better picture, does anyone know where I could find them?
thanks for your help

Let me try to be as clear and as helpful, as I can. "Divxmpg4v3" is DivX 3.11 alpha, also known as "DivX 3 ;-)", also known as "DivX 3".

DivX 3 is included in the Gknot suite, and is one of the three codecs Gknot is designed to work with. You will find it in the Codec selection area on Gknot's Bitrate tab.

DivX 3 encoding with Gknot is done through Nandub, which is a VirtualDub variant installed as part of the suite.

You can use DivX 3 completely automated, as you would DivX 5.

You can also do a lot of manual manipulation.

Start reading about Gknot and DivX 3 encoding here (http://www.doom9.org/divx-encoding.htm).

Doom9 has a DivX 3/4 forum (http://forum.doom9.org/forumdisplay.php?s=&forumid=19) where this codec is discussed.

There is even a FAQ thread (http://forum.doom9.org/showthread.php?s=&threadid=16981) there. Doom9 writes of this codec in the top page of his DivX Guides:DivX3.x ... is the more well known and has been around for a while. It's also known as DivX ;-) and is basically a hacked version of Microsoft's MPEG-4 v3 codec. {It} has been around a while ... {but its} legitimacy is to be doubted, the codec by itself is not very controllable and only very advanced (complicated) encoding tools will give you something as size predictability or in other words, making a movie fit on a certain number of CDs is a pain. I understand your claim, that you are downloading legal content. But we are very strict on our interpretation of Rule 6, and we can not verify nor validate your claims. Commercial trailers are sometimes made available to the public at large for download, true. I can't think of a single commercial trailer that has been encoded into this codec by the distributor, as this particular codec has problems with its history.

But far, far much more copyrighted controlled content is shared on the internet. Due to the prevalent nature of intellectual property available on the internet, and our need to avoid repercussions from the appearance of supporting "file sharing" in any way -- we are very strict with our interpretation of Rule 6. You are not required to like the rule, but you agreed to it when you joined this forum.

@jggimi: very, very nicely said... i think we got to incorporate this into the sticky somehow!

@9inchNAIL: we're not as picky about this topic because it is fun for us, but because we want to protect this forum, the site www.doom9.org and the creator of it all, doom9 himself. now by talking about illegal content, which yours may or may not be, we endanger the whole "project" and therefore we do not allow it.
hope you understand

I understand with the whole legality issues of it all, and I
guess there's no real way to validate anyone's claims as to
whether they're using GK+encoding for legal purposes or
otherwise. I'll certainly abide by the rules, and be the first to
tell anyone off I find on here doing otherwise...!...
thanks for the links, very helpful- top notch site- very informative
