A lot of you asked me how to have the pdf of my Max presentation. The answer is simple: here you find the .pdf and here the entire session recorded during Max. Thank you all for the support and the appreciations received before, during and after the conference.
Many thanks to Kevin Towes, Desiree Motamedi and all the Adobe’s staff for have made my presentation at Max possible.

H.264 Encoding and delivery Best Practices @ MAX 2009

21 September 2009 9 comments

Only two weeks and the 2009 edition of Adobe MAX will begin.
This year in my presentation ( Encoding Best Practices for H.264 Video Using Flash. 5 October 2:00 pm Room 506 ), I’ll focus on changing the usual encoding perspectives proposing a dynamic approach in choosing the best resolution – bitrate mix.
Dynamic is always better than static, you know, and it’s much better in video encoding: reach a wider audience and save money!
I’ll also focus on playback best practices (full-screen acceleration, visual enhancements and so on).

Because a picture is worth a thousand words, today I want to show you the real potentialities of these approaches…


Me vs YouTube

In this test, I have downloaded from YouTube the video clip of Bjork “All is Full of Love”. This clip is an High Definition video encoded by YouTube in 720p (1280×720) at around 2Mbit/s.

The same (already encoded) video has been then re-encoded at a much lower bitrate of 500Kbit/s with a specific set of encoding parameters and pre-processings. I think the result is very good, and strangely enough, somewhat better than the original.

How can 500Kbit/s be better than 2000Kbit/s ? How can the quality improve re-encoding a damaged video at a quarter of the original bitrate ? Well, you are all invited at MAX 2009, 4-7 October in Los Angeles to discuss this and other topics.

Here you find the demo page

Note: decoding two HD video at the same time requires a fast computer. On my Core2Duo @ 2.2GHz Windows laptop it works very well.
Remember also that IE is faster in Flash Video decoding than FF.

But now let’s take a look by yourself and don’t forget to send me a feedback on your experience. What is the better looking video in your opinion, both in browser and at full-screen ?
