go to this web page

Why 3 D to 2 D?
well this has made because I have too encode one movie sterioscopic "3 D" to 2 D my system is not good (I don't have all hardware). So I add to found a solution for encode 3 D to 2 D, I goggle it but only found how to encode (convert) to 2 D to 3 D. Them came to me the idea try this on MEgui, well the result has amazing, but this as made on Windows, and I want try to on Ubuntu in Avidemux, so I use the sample of to make this "how to".

"how to"
This is on Ubuntu 10.10 64bit this sample of the "how to" take 30min to encode on my laptop 2hz coredue 2GB memory, your miles may very.
Start, go to Applications, Sound & Video, Avidemux, (if you don't have this install it, using Software centre),
locate the file to encode (convert) by click on open,
the stereoscopic "3 D" look like this, we need change the video codec, audio & format, we want keep the quality so for video MPEG-4 AVC, audio AC-3, format MKV.
after you choose the video codec, you can use configure, for the encode,
encode by ["encode mode" (single or dual pass)], ["target size" (if is for a single dvd 4Gb], or ["quantizer" (big number to low, from 51 to 0, but 51 bad quality 0 best quality).
by default the max ref. frames are 3, but I use 4, don't go over 6, software like multiAVC will claim about it.
"filters" menu where we need change a few thing for the best end result,
on transform filter use resize, crop & resize but this is only necessary only like this case the sample is 3000x800 so resize first to 1280x720, them crop 640 & resize again to 1280x720,
                                           3000x800 to 1280x720

destination 16:9 and lanczos3, [on MEgui is lanczos4]
screenshot of correct sise 1280x720, now crop,
half of 1280 is 640 input that on with and click enter (return key),
choose from left or right to crop in to half,
them resize again to 1280x720, from the filters menu you have to use for this first resise MPayer,then crop and last resize with avisynth,

screenshot after all the settings apply,
save the file for Avidemux start the encode, my is avt.mkv, in Avidemux you have to add .mkv to the end of the file and after the encode  use the MKmerge to change the internal name of the file "tag" for the name that you want.
Mkmerge gui

in Mkmerge, file segment title, under global tab is "Avidemux", change for the name that you want or clear it, is up to you. MEgui you don't need do this, so that it I hope this will help someone.
The end result to compare here:

JDownloader your Manager

After doing the latest update to Ubuntu 1010, Jdownloader stopped working, so I had to install it again. I went to the web site and click on the download link to Linux and this time I used the script.

This is a bit confusing to understand because the instructions on the web site is vague , so the reason of this post. Click Download Then right click, "" file
Properties, Permissions, click, "allow executing file as program". Opens the terminal,

and using the "cd" command to change directory to the location where the "" file. Now you use this command "chmod + x", this command causes the script executable I think, clouse terminal, click on "" file and a window will appear,

click run in terminal now "jd" will be installed, when you finish the installation, click "" file,

and again a window will appear, click Run. Now is the time to create the launcher of the program,

the top panel click "add to panel",

choose "custom applicatiom launcher"

icon can be found at "/.jd" folder,

name "!!", command, I change the "" file to "/.jd" directory,

and this is the end of the installation of jdownloader, maybe it helps someone.
