ogg format ready for primetime?

[canadian_fbi]

hi there. just wondering if with all these problems being reported, whether or not people are actually encoding their movies exclusively in ogg or if this is still solidly in the experimental stage and ogg is simply not reliable enough yet to move away from the tried and true methods.

[Doom9]

well.. that is always a question of definition. Most of the programs we're using to rip are somehow in beta status and yet we don't question them (okay... flask aside).

I'm sure there are people using ogg for all their rips, I've actually started to use vorbis and ogg media streams, too. Atm I'm playing with subtitles in ogm streams. I also use xvid ;)

[meleth]

For ogg the only thing thats holding it back is the directshow filter. Once it supports multistream,multichannel and subtitles it should be fine to use ogg. Ofcourse this depends on your target audience.

[Doom9]

subs is there. If you read my updated ogm guide you should know that multichannel encoding is still far off... it doesn't only require a working filter.. but to really be smaller than ac3 the vorbis core still needs a lot of work or you'll either have to live with degraded sound quality or sizes that don't really differ much from AC3

[meleth]

As i understood it headac3 already supports this? To be honest though i don't need multichannel support since i only do anime anyways and they're rarely anythign else but normal stereo.

I'm doing my movies as *.ogm at the moment (since 0.9.8.3...). 3 so far, 4th and 5th are coming now. No problems so far, I enjoy having 2 languages on the same CD instead of needing 2 CDRs for having both languages of a movie.
I just tested that on another computer with just active boxes attached and it sounds perfect. On my stereo though, you hear the "aliasing" effect of such low audio bitrates(I target 64kbps per language...), but those aren't much worse than using 96kbps mp3 audio...

Doom9, just out of curiosity, which XviD version/build are you using?
What do you think about the quant_type_modulation?

Well i never said that subs and multistream weren't in, just that one of the requirements befor eyou could start considering releasing stuff made it. The biggest reason why i am looking into this is that you can mux both audio streams and the sub into the avi itself. Smaller filesize is just a bonus for me. Not to mention that vobsub has gone shitty since .05 and refuses to work anymore. Might be that is has somehting todo with dx 8.1 although i'm more inclined to believe that there's somethign wrong in the registry. Might be that it is dx 8.1 that causes this though.

All I can say is that several of us already have moved away from AVI and MP3 weeks ago. When D A released his latest HeadAC3he 0.21, which supports bitrate predictabilty, I now have no reason at all to use MP3. Doom9 and Everwicked have great guides to mux the audio.

I've also moved away from Divx and moved onto Xvid. These are glorious days for us. Xvid-Vorbis Audio all in a nice clean Ogg container. Now were talking:D

Well as far as i know xvid is still not an "approved standard" so to speak, while ogg is.

@koepi: currently Nic's compile 13/2.. don't think that has the quant_type modulation in yet. Though as long as I'm still in my exam period I'm not doing much encoding, maybe one movie a week. So I'm afraid at this point I cannot give any useful feedback on the new XviD features.

When did Ogg become an approved standard? I guess the container is somewhat mature. Then again...Xvid is maturing everyday and it certainly shows with each new build.

[meleth]

Well i have high hopes on xvid and divx4. Sooner or later they should be able to produce better results than divx and when that happends you can be sure i'll switch over to either of them.

XviD already do for me;)

I think it's already happened my friend:) Have you tried the latest build? Absolutely amazing quality, not to mention my encoding speed.

No, i haven't had time to do that yet. Been busy checking out the new ivtc filters and playing with ogg trying to find out a better wya todo sub-dubs. I am curious however if anyone of you have had a chance to encode any anime? And if you have if they also turn out better.

At times i hope that someone would write an anime codec to be used for the sole purpose of encoding anime, since that is quite diffrent from normal movies.

[Koepi]

I tried "emperors new groove" if you count disney as cartoon.
Amazing quality with XviD playback, DivX4 DS filter screws up a little here(setting post processing to 0 makes it a lot better though)...

hrm guess i'll have to find time over the weekend to test it out then. What troubles me is that there seems to be two tracks of the codec, yours and the other one. So i think i might wait until yours as been commited into the cvs before testing it.

[canadian_fbi]

i think i'm going to do some testing of ogg/xvid this week or weekend... i'm sure it probably gives better quality for the bitrate than divx4/mp3, but there also seemed to be a lot of bug reports popping up.

the main reason i got curious about this i suppose (in addition to the increased quality) is that a couple of divx movies i'd burned to cd had choppy playback at two points for about five seconds. it seemed that the cd-rom drive wasn't reading them fast enough. i tried burning other cds with the same result. playing them off the hard drive solved the skipping problem, but you could notice the increased hd usage at that point. the scenes weren't terribly high action or anything, so i suspect that it's the vbr mp3 muxing that's having something to do with it (one was 800/150 video to audio, the other was 1300/190). either on one of doom9's posts or guides or somewhere else i read that this problem could result from the rather hacked together implementation of vbr mp3 muxing in avis. so if this is the case, i'm hoping ogms will fix the problem.
