Thanks for the nice tips about HD on YouTube. I need some advice. I have 640x480 videos that I want to upload to YouTube. I want YouTube to keep them in 640x480 instead of reducing them to 320x240 as it does. Is there a way to do this? My files are in the following form: Container: avi, video: H264, audio: mp3 , 640x480 pixels, 30 images/s. They come from a DMC-FX10 Panasonic compact camera, and I process them with "Format Factory" before feeding them to YouTube.
