Rmvb VS H.264,,,有人专门做了测试，并放出结果和文件下载

KonW@2007-05-29 19:02

最近开始看英文字幕的动画，发现一个郁闷的问题，国外的都不用rmvb，结果是所有最小的就170mb，，，在论坛上和他们交流了很久貌似他们一致认为rmvb很垃圾，我帖出图告诉他们的一个177mb的片是多么不如这边的一个100mb的rmvb,结果扯了半天貌似h.264,,,,

Well, there have been some interesting posts in this thread with interesting claims that I wanted to test. The argument comes down to how they compare, using the best tools available. It's no good having some mythical Real encoder that can do 25mb encoding if you don't actually have access to it.
One RV10 encoder I did have acess to however is Real Producer Basic. It's the Real Thing from Real Networks (), the only thing it doesn't let you do is change the predefined profiles. To work around that, I found a profile that used the highest possible quality settings at a lowish bitrate (350kbits), and then encoded the x264 to the same bitrate. No audio encoding was included.

The source:
The file was Honey & Clover II HD - 01 [Solar-IDE][9304C110].mkv, a 720p 24fps "good-enough-for-what-I-need" source which was noise free and with no banding. It's still not licenced, right? Passed it through an AVS script to make it a little more compressible:
directshowsource("Honey & Clover II HD - 01 [Solar-IDE][9304C110].mkv")
killaudio()
bilinearresize(480,272)
Dup(threshold=0.8,blend=true)
removegrain(2)

The x264 Encode:
x264.exe --pass 1 --bitrate 350 --keyint 999 --ref 16 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --b-rdo --bime --weightb --direct auto --filter 1,1 --subme 7 --trellis 2 --analyse all --8x8dct --me umh --progress --cqmfile "m4g-lrm.cfg" --thread-input --threads 3 --output NUL "hctest.avs"
x264.exe --pass 2 --bitrate 350 --keyint 999 --ref 16 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --b-rdo --bime --weightb --direct auto --filter 1,1 --subme 7 --trellis 2 --analyse all --8x8dct --me umh --progress --cqmfile "m4g-lrm.cfg" --thread-input --threads 3 --output "hctest.mkv" "hctest.avs"
pause
Nothing special here - options were reasonably normal. Special interest is the ...'interesting' GOP size and that's about it. The matrix is sourced from here.

The RV10 Encode:
Done through Real Producer Basic. I used the 350kbits 'download' profile. Nothing interesting otherwise. I enabled 2pass.
(使用Real Producer Basic ,350kbits "download",开启了双通道?)

The Results
Here is the first 10 seconds of both full encodes. The screenshot is frame #50.
(这里是前十秒,截图在第50Frame )

rmvb 下载完整版 (full encode)

h264下载完整版 (full encode)

Of note is the size difference, there's obviously large differences to RC under the hood.

I think the first 10 seconds give a very good indication of the rest of the thing, if you reeeally reeeally need it I will post the whole things.

EDIT: I forgot
The Conclusion
China sucks.

EDIT2:
h264 on the left, RMVB on the right.

Not the same frame... I'm lazy.

Notice the funny colour in the RV encode.

Through this entire sequence the longer it goes on, the blockier and blockier the RV10 becomes. h264 stays nice and consistant quality, not to mention no smudging in sight!
(结果h264一直保持清晰但rv10却渐渐模糊)

两个文件都小于60mb且相同大小，，，

依稀记得貌似有一个观点说“x264会最终取代rmvb”..........

2pass翻译双通道？？

(这里是前十秒,截图在FPS 50?)

哪来的fps？frame number啊

RMVB并没有想像的那么差
因为输入片源差＋网上教程很多就在误导＋压的人本来就追求量产＋一定要压到某个大小
所以RMVB变成了劣质的代名词

那你说翻译成什么我就改成那个就是，，，，— —

恩，他们说以前很多观念认为rm的很差，所以一直就延用下来了，所谓的第一印象很重要，，，我觉得中国如果bt+动画字幕刚开始出现的时候网络条件像现在这么样普及avi/mkv可能也一样会成主流，实际上有些快帧的地方rmvb看着确实很郁闷，比如darker的06的后面有个打的地方不停的下着雨，那个画面简直叫模糊+模糊

幸运星我压过第一话1280x720 x264[ogg 64Kbps] 92.1MB VS 字幕组发布的 RMVB 704x396 95MB

不过Real的品牌效益比x264要好得多然后很多人认为x264占用很高的系统资源就54H.264标准了[实际上这里面某些人的机器能够完全流畅播放]

小道消息谣言以讹传讹 Orz

超底码，底码下，VP7可以轻易盖死除H264外的编码~不信去试试吧~

有哪个字幕组能不压RMVB的,我立挺啊.没必要我完全不想压这东西...

可能还是有很多人只是装了real，没装暴风之类的吧。
成了一种习惯。
不是早就有观点认为h264比rmvb强么
