I tested by using another softwares. The root cause is the original video's frames rate, i met 2 cases both of them has 24 fps. The 29.97 fps video is suitable for internet streaming than any others.

Then, Encoder software is the another issue with them. I usually use TMPGEnc with the preset optimize for small size but high quality (it need more computing power). Last night, i have tested by using Adobe Media Encoder with the same preset with TMPGEnc... it's end up like TMGPEnc. In some encoder for common user like AVS Video Converter, the quality of result can't be compared to 2 of above but the video end up is OK.

Maybe this is the bottneck of mp4. So, Youtube doesn't use mp4 for preset 480p of their video. I usually see the FLV.

I suggest the Pseudo-Streaming FLV feature for LiteSpeed.
