I am using Sony Vegas Movie Studio HD Platinum 10. The original files are 1920x1080 AVCHD from Canon HG20.
What is the best rendering format for Youtube HD? I found there were two different format suggestions through out the internet. The first one is Sony AVC m2ts 1920x1080-60i. The second one is V11 wmv 1440x1080.
I did the tests on both. I donít see the quality difference shown on Youtube HD. However, the file size of m2ts is almost three times larger than that of wmv. For shorter uploading time, wmv is definitely the choice here.
Another advantage of wmv 1440x1080 is Youtube gives the choice of 1080HD and 720HD selection on watching the video. There is no 720HD selection for m2ts 1920x1080 videos.
My question is why people suggest using Sony AVC m2ts 1920x1080-60i format?
P.S.: Flickr does not process the wmv 1440x1080 correctly. It can process wmv 1280x720 or m2ts 1920x1080-60i well.
