Encoding high quality h.264 / aacPlus v2 media for web streaming with Flash 9, version 2.

Update Notice

This post has been updated with a newer and improved script and instructions, please visit the new one HERE.

It was some months ago when I wrote a tutorial about how to encode good quality h.264 video with aacPlus audio in order to use the great capabilities of the new flash player version 9.0.115 (that in case you missed it, now can play h264 video and aacPlus v2 audio).
Due to some personal convictions for my prior tutorial, i decided to use FFMPEG, and while it does the job pretty well, it has some limitations (specially in the video scaling / resizing area). So in my particular case, I had to use several php / bash scripts in order to feed the encoders with the proper resizing data, etcetera.
Well, let me introduce you to the 2nd version of my h.264 / aacPlus v2 tutorial.

This time I used Mencoder, an amazing tool that comes with the mPlayer package, and i also created what i think is a really nice bash script to make the process almost 100% smooth and simple.

These are the things you will need:

Creating good quality h264 video for the upcoming Flash Player and Flash Media Server

Friday, September 28th, 2007

Important

This tutorial has been updated (and improved) a lot, for the new version please follow this link.

UPDATE: I realized that when i read a tutorial about anything, in most cases, i want to first see what result im going to get so then i can decide if the tutorial is worth reading (or not), so here is a head by head comparison: 

This is an h264 file encoded by the guys at apple.com, it’s the TV Commercial for the brand new iMac: ORIGINAL VIDEO

This is the same file re-encoded using the steps on this tutorial: RE-ENCODED VIDEO

Obviouisly, there is an small quality degradation, but keep in mind that apple’s original movie is 14MB in size, while mine is 1.5MB ;).
You can play my MP4 video with almost any video player out there, but remember that not all video players out there support HE-AAC audio (or aacPlus) and b-frames, so if you play the file with a player like QuickTime, it is NOT going to work.
I recommend mPlayer or VLC media player to play this kind of video, and obviously, Flash Player will play the file perfectly too.

Update for Macintosh users:

I updated the bash script on this post so it can be used also by Macintosh users, so instead of using the NERO Digital AAC Encoder, Macintosh users can take advantage of the native 3GPP AAC Plus V2 encoder that i just compiled. Visit this post for more information about it.

Like a lot of people out there, i was really happy when i found the press release from Adobe, stating the addition of h.264 video support and HE-AAC Plus audio to their upcoming Flash Player versions, and also, to the upcoming Flash Media Server.
After following several “Tutorials” all over the web, i found that there was not any single one that gave me the results that i wanted; that is, good video quality, with the less possible file size, so after a lot of trial and error and after a lot of help and optimizations by the guys at the ffmpeg and x264 IRC channels, i decided to create this tutorial that will most probably help you a lot to encode good quality h264 video, with HE-AAC Plus Audio, and all this inside an MP4 container with tags and all ready to deliver to your visitors.

There are several things that you will need in order to do this:

Some friendly bookmarks:
SVN checkout for x264:
svn checkout svn://svn.videolan.org/vlc/trunk vlc-trunk
SVN checkout for ffmpeg:
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

First of all, I’m assuming that you are running Linux, Mac-OS X or any other UNIX variant. I never tried this on windows because I am pretty sure that there are lot of really nice programs that you could buy to do the job.

Apple’s Think Different TV commercial, in good quality…

Tuesday, September 25th, 2007

As many of my friends already know, im working on an online archive of Apple related commercials and institutional videos, so well, some days ago i received a series of uMatic tapes, and i found this inside one of them.

This is, in my humble opinion, one of the better (if not the better one) examples of clean institutional advertising & branding, and one of those commercials that “touch your heart”.
Quick Tip: In recent pre-releases of Mac OS X Leopard, you will find the whole narration for this commercial in the high resolution icon of the “Text Edit” application.

I hope you enjoy this, because you wont find a better quality version in the whole web ;)
Please note that you will need a 512kbps internet connection (or faster) in order to watch this video without interruptions.

Quote from Wikipedia: “Think Different was an advertising slogan created for Apple Computer in the late 1990s by the Los Angeles office of advertising agency TBWA\Chiat\Day. It was used in a famous television commercial, several print advertisements, and several television advertisements for Apple products. Apple’s use of the slogan was discontinued with the start of the Apple Switch ad campaign in 2002. The slogan may have been a play on the venerable IBM Think motto coined by Thomas J. Watson.”
