Please explain bash$ mencoder -ovc x264 -oac mp3lame -x264encopts \ subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid=normal:weight_b \ -o hoax.avi ray_480p_normal.mp4 then o god o god.. is this a porn?

Read this page: http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-x264.html Each of the keys in the string has a value which is explained in the document. Basically they're claiming something revolutionary, which in the end is just using the x264 encoder with the right fine-tuned options.

They're not "fine-tuned" in the slightest; they're cargo cult options that are going to give worse results on a compression-per-speed basis than the presets that already come with x264. Many of those options are completely redundant; they're specifying things that are already default!

There are quite literally dozens of scam companies built off x264, claiming in many cases that they made an "incredible" magical proprietary encoder with "revolutionary" compression. Of course they just run x264.

Fortunately it is extremely easy to identify an x264-encoded stream, even if all the headers are stripped and rewritten: it would be extremely difficult to modify x264 to cloak such a stream entirely unless you knew the code line for line, and even then, some of the features of x264 that are responsible for much of its compression advantage are extremely obvious in an analyzer (variance adaptive quantization).

Fine tuned in the sense then that it's beyond the defaults.

It means the _normal.mp4 file was encoded in an absurdly high bitrate for no reason except to make their claim of 90% compression.

You hit the nail on the head here. While it's possible that the video they posted is 6fps (which is close to what those mencoder flags will achieve), it's more likely that they simply saved the first video with no compression and saved the second one as a regular video file with compression.

This is crazy... the website is a shell of an investment pitch. These guys need to get reported. Anyone want to make some money off the collapse. Wow, their first 'contract' is with a company called edgefactory OMNIMEDIA, which I think is owned by martha stewart OMNIMEDIA? edit: Wow, I just posted a link to this article and this thread on their facebook account and now the item has been deleted off their wall within…

that's OMinous...

But it isn't, really. If you want to trade compression for speed, the presets listed on the top of the help page are far more effective.

subq=6 Default is 7. This makes compression worse.

partitions=all Higher than the default, but for negligible gain. This is only enabled on the slowest presets.

8x8dct The default.

me=umh Higher than the default, for small gain.

frameref=5 Default is 3; 5 gives small gain.

bframes=3 The default.

b_pyramid=normal The default.

weight_b The default.

OP should contact some hedge funds with this info. If true they will be quite interested.
