H.264 Encoding and delivery Best Practices @ MAX 2009
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.
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 ?
