View Full Version : Why do I use DivX and not XviD?

I have been using DivX since 3. But I am wondering why I am not using XviD. XviD wins the codec shootout every year (by a small margin). The new DivX converter is a joke, the DR2 is not ready for primetime. AutoGK does not support the latest version of the DivX codec (without a hack). The tools (AutoGK, MPEG Mediator, avi.net, staxrip) for XviD are just as good as the Dr1 ever was; if not better. Encoding is slightly faster in XviD.

As long as you keep qpel and gmc turned off in XviD the final avi file will play in my standalone player and my pocketpc.

I orginally thought that DivX would overtake XviD since they generated revenue and had funds for R&D; so I happly paid them, but that never happened. And now it looks like the world will move to AVC coders before DivX will catch up to XviD.

Someone tell me why I should stay with DivX.

Someone could always find something to tell you regarding why to stay with a product and not switch to another, but that's not the point. What's important is to make your own mind what matters to you. I can summarize what matters most to me: I want the best visual and overall (speed, integration, etc.) quality, so I read up and I test on my own what works best, and make up my mind. I don't just listen to people who tell me why I should and shouldn't do this or that.

Well, your money were not wasted. DivX is getting near the Xvid quality and speed. They made (hacked) a container to make it support menues, subs and other goodies. They're still working on integrating all the possible stuff that will make DivX (and xvid too!) even more supported by hardware manufacturers.
So, i dont think your money were not well spent. Remember always what DivX done, and if you have a SAP that can play your DivX/Xvid encoded files you should thank DXN which made this possible.

It seems that often the less you pay for a program the better the support from the author(s) and the more often it is updated, and of course you pay less for the updates.
With some of the larger companies you get nothing but an autoresponder message promising to answer soon (and I wouldn't hold my breath when their autoresponder messages take 3 weeks to go out (No this wasn't Divx).

Well, nobody said that Divx devices will be wisely supported as DVD MPEG-2 during 10-20 years. There is no any document.
There aren't DVDs in .divx format. You're on your own.

Heh, well, since "DivX format" is actually MPEG-4 advanced simple profile, I'm quite sure a lot of players will support that.
The avi container, with packed bitstream and stuff like that, sure, that may be a problem, but who cares if you can remux into .mp4?

I use a fixed quantizer of 1 for DivX 6 encoding... at this level, DivX outperforms XviD by a significant margin in pure quality. It seems at lower bitrates XviD has the advantage though?

You tried to play with CQMs?

I've seen the Divx name on the outside of lots of DVD players. That cannot be said for any other codecs.

There is your answer.

I don't understanded. What is the advantage of that? Only that it is more popular?

It's like a safety blanket.

Point being though, if it says DivX on it it's more-or-less saying it'll play Xvid aswell.

Gives you the same chance as with any DivX material at any rate

I have two standalones, they both play Divx, only one plays Xvid.

Ok, so you might need to change the fourCC for some (Sony?) players. Still plays XviD though.

Could be to do with having the wrong level of GMC or bframes etc in the Xvid files, but AFAIK you can generate DivX files that break these rules too

This will be advertising, but I have an almost one year old LG dvd&divx player, which can be update via cd and playes DivX pro, divx6....and, plays xvid, sometimes it has a problem with higher bitrated xvids, but plays them. My friend bought an Philips player with played xvid perfectly.

Getting a little of topic.. I have a JVC XV-NP10S and for some reason the player decodes xvid videos much smoother than divx. Low bitrate xvid videos look much better compered to higher bitrate divx videos. There are almost no blocks when viewing xvid videos while divx videos show alot of blocks.

Why do I use DivX and not XviD?

Divx is faster converting, on my P4 2.80, 512 Ram divx outperformes xvid on the speed of conversion.

Video quality is a bit better when using Divx.

Uhm... exacly the opposite of what doom9 found in every divx vs xvid comparison.
Maybe you should check the settings :p

Hacked? How is the container hacked? That implies some half-baked solution.

.divx is an "extended" .avi...

-For standalone DVD players, use XviD without Qpel ,GMC!!! and maybe? CQMs. Packet bitestream in XviD is debatable. Use classic Open-DML AVI (VD, VDM), not RecStyle (AVImux).
-For Pocket PC use XviD without Qpel,GMC. Use Bulletproof's Heavy Compression Matrix (or other ultra-compression/ultra-low-biterate matrix) and One-Pass with fixed quantizer 2-5 or more (as you like) encode. This should beat whatever other codecs including AVCs (I mean optimal size vs video quality vs baterry life).

My standalone DVD player eats CQMs and Qpel. GMC partially (jerky).
I make encodes for my PPC with Q4 Xvid+96kbps Mp3, movie size 150-250Mb.
