I apologize. I was not directly attacking you. XviD is pretty terrible when in comes to quality and I wasn't personally attacking you for saying it's high quality. I was simply attacking the fact that people think it's high quality for whatever reason.

I'm going to reply to the post in the video thread countering some points you made, but do not take them as an attack against you. I will simply be stating facts about H.264 and x264.



Also, for the record, videos encoded with x264 can easily produce a video that has a smaller filesize while still looking incredibly better. That's H.264 for you. XviD is a thing of the past. ;)

I'm sorry too, But I feel EXACTLY the same as dopefish about XviD.

XviD is pretty terrible when in comes to quality

I'm not trying to throw gasoline here, but you must be saying that XviD quality is terrible given a certain bitrate, right? (vs. similar bitrate with H.264)

-edit-
Well I see that's exactly what you said in the last sentence of your post, so question answered.

With nothing to compare it to, wmv has insanely high quality! :wink:

I've always addumed folks think it's teh best codec because it's no damned popular. Same with .mp3.

Ooooo how much mp3 pisses me off. Why couldn't everyone adopt somethig nbetter? Arg.

But they're popular and easy, so i['m sure they won't be going anywhere soon.

Indeed. I prefer AAC over MP3. AAC is a much newer specification than MP3 and it was designed to overcome many of the drawbacks in MP3. It is a better codec. AAC at 128kbps is better than MP3 at 160kbps or higher, and it only scales up from there. The resulting filesizes are smaller, too.

The same can be done with x264 versus XviD. You can actually encode with x264 at a lower bitrate than XviD, and have a better looking video and a much smaller filesize.

Apologies accepted, and sorry if I sounding like a complete ass in my responses. I have some interesting videos I'm about to post tonight showing my preliminary tests between Xvid and x264. Had I known that AutoMKV makes it so easy to use, I'd have tried it before. I have been rather influenced by the huge file size differences I've seen on TV show archiving sites though. The x264 ones are generally nearly 3 times the size.

I don't want to give away too much as far as the results of my test here for two reasons. I prefer it be chatted about for the most part where it's posted, and I am too new at x264 to know the best setup yet. In other words I haven't even bothered experimenting with settings like qp_min or psy yet. THAT is the main reason I call the test preliminary, it's going to be a work in progress for me, but I must say, so far it hasn't been as daunting as I thought it would be.

I got a couple warnings in the process of experimenting with compression settings. One was VBR <######> Level Limit ######, the first number being about 5,000 above the second (eg: 25000 vs 20000). At one point I knew I was trying a bitrate too high because I got a warning saying try reducing qp_min, current is 10. I didn't bother changing these parameters because qp_min not being seen anywhere but in the command line appeared to require editing it, and of course the bit rate leveled out as I got better at setting it.

The results are rather surprising to me so far. I must say, little did I realize x264 could compete so well in the small file size arena and still retain it's legendary image quality. Truth be told though, I had to zoom the 640x480 videos full screen to really see noticeable differences, but they're definitely there. I imagine the most noticeable differences are at 720p and up resolutions.

On AAC, last time I tried it, via sampling iTunes a while ago (which I despise), it didn't sound as good to me as wma, and not even any better than LAME. Since I've been using Xvid though, I've been using mostly LAME. If AAC can be used with x264/MKV though, I'll give it another go. Upon installing AutoMKV, I noticed there was an option regarding Nero, and I thought it said something about AAC too. I opted out of the Nero thing because I didn't think it would apply to my uses, even though I burn with Nero.

The warnings can be ignore if you're just going to put the videos online. You'll notice when you encode with x264 that it will have a target level, 4.0, 5.0, etc. There are exact specifications that you need to comply with for these levels if you want to be compatible with the specification. For example, if you want to encode a video to be played back on the PS3, it must conform to level 4.0. Exceeding the bitrate for that level will spit out a warning letting you know. If you are just going to play these files back on a PC and nowhere else, then you can ignore the warning.

LAME is the highest quality MP3 encoder out, and yet AAC can still have better quality bitrate for bitrate. Just like with LAME, though, depending on the encoder there are plenty of options to tweak the sound. Comparing with iTunes may not be the best. neroaacenc is pretty high ranked in terms of output quality. I think for the best comparison you should compare LAME to neroaacenc.

As for the audio format with MKV, you can pretty much put anything you want in that container. MP3, FLAC, AAC, WAV, etc., etc. It's really a great container. MP4 has more popularity and support over MKV, but MKV is superior in features, audio/sync, etc. They're easily interchangable, though. You can easily extract tracks out of both MP4 and MKV containers so you can switch between the two very easily.

Go ahead and download the Nero AAC, it's nothing to do with burning, it's just a codec they've made. The link in AutoMKV doesn't work, use this one. Put it in your BeSweet folder. :)

OK, thanks got em in there now. It didn't show up in the drop downbox at first but then I realized you have to take them out of the folders they're in. I'll give it a go next time I compress.
