Here's a tip for you guys who present videos on your websites.
Did you know that there is metadata encoded into the mp4 file and it (stupidly) is encoded at the end of the video. This means that a player like flowplayer, gddflvplayer and most others download the entire video to your browser before playing it. I discovered this only by noticing two videos, same filesize and same bitrate, but one started playing immediately in my browser while my Cyberlink-PDR created one took ages to download before starting.

The trick is to get a copy of MP4FastStart.exe and process your finished mp4 file before uploading to your server. I show here a look at the beginning of my mp4 and then again after MP4FastStart and the metadata has been written to the beginning of the file !
Remember to run as administrator if you use Vista
Now the video starts playing immediately in the browser !

Might I suggest that the boffins in Cyberlink HQ automatically code this as a default since it is crazy to put it at the end of the file (Sony and other nle editors have the same problem) Google forthe MP4FastStart site

If you can't solve the problem - Change the problem
