Question on really good conversion and compression.

[poisondeathray]

My understanding is that he was simply saying, an overcompressed encode of a BD might look worse than a retail DVD .

That's it

I don't see any " weasel words "

By the same token, weasel words are not the basis of a sound argument.

Nice try. There's nothing like showing up here just to derail someone else's thread by making fallacious arguments against points that were never made. And then claiming foul when called out on it.

Reminds of the 'Big Nose' sketch from 'The Life of Brian'!

Yes they are.
Good Morning!...

...weasel. (loosely taken from argument sketch)
Sorry, just had to use one of those "weasel" words.

Wow, quite a bit has been going on here since my last post. I an answer to the question that the person used to rip and post the 2.2GB MP4. I asked him what software he used.

anydvd hd.... x264, avsynth, nero-aac... various other components

I am guessing x264 is a codec. I am not sure what Avsynth is. I looked it up and it seemed to be a command line utility. I am find with commandline utilities, but is that all I need, he states various other components. I am guessing he doesn't want to get rid of his secret sauce. Any ideas?

Again, the help has been amazing and I really appreciate it.

Thank you!

Any ideas?

What you mentioned are the tools a good video enthusiast and encoder would use to compress the hell out of something, especially AviSynth.

You might ask him the AviSynth script he used. But he might not be willing to give it out.

I am guessing x264 is a codec. I am not sure what Avsynth is.

x264 is encoder that encodes H.264 video. It is a command line program or you can find a lot's of GUI's for x264 here on videohelp
Avisynth is sort of frame server, it doesn't encode. It reads script that consists of some lines of text. It knows tons of commands and treats video accordingly. Script can have just line:

AviSource("video.avi")

where it just loads video or couple of pages of script that filters video, adds filters etc.
for example , two line script with one resizer (filter):

AviSource("video.avi")
BilinearResize(640,360)

where video.avi is 1920x1080 and BilinearResize resizes it to 640x360

Finally, after you install Avisynth, you just load that script - meaning text file saved as avs instead of txt - into encoder and it will accept it, kind of moment of awe for everybody that did it first time. It looks like you are loading text into encoder but Avisynth works as frame server in the background, reading that script, executing those filters and serving produced video frames into encoder. Encoder needs it, Avisynth serves it. So there is no big uncompressed intermediate file. Only perhaps certain limited number of frames somewhere in the buffer.
Use Avisynth for unique video you have - home videos, producing something as videographer or just for some YouTube fun etc... ,screw the movies

If that's what he intended to say, why couldn't he just say it just like that? Why all the misleading rhetoric?

The x264 is a library can be used to convert and manipulate H.264/AVCHD video. The Nero AAC codec is used for the AAC audio stream. That's the core logic, and it's nothing special. AnyDVD HD is a ripping program, so chances are that the original source was a BluRay disc. AviSynth helps automate the process. (Looks like it does more than AVI files.)

The bottom line (still) is that H.264 can produce some amazingly good output at low bit rates. That is, after all, what H.264 was developed far originally.
