I dont have it all figured out yet, but I thought Id muddy the waters with a few free apps that may be of some help. I have been using HDVSplit to capture HDV from my HV30. From there I convert the m2t file into mpg using MPEGStreamClip. You can deinterlace the file and set your output size to 720p when converting. I must say, that when the file is converted to mpg it is perfect…however what I have not figured out is how best to prep for Vimeo. When I upload the file still appears to be interlaced even though I deinterlaced it with MPEGStreamClip.
There are some forums on Vimeo that may be helpful, but when I tried them I got worse results than when I did the above.
So, who knows…maybe one of these apps will do something for you. Both are pretty fast so you wont waste too much time if it doesnt pan out. If you figure something out, please let me know!
