As we say in the FAQ, use Share/Personal Computer/DV-AVI to output an AVI and then use Windows MovieMaker to output a WMV from that rather than publishing directly to YouTube, then follow the rest of the instructions here:
I guess I'm not communicating. I DID try to use the forum and FAQ etc. to find the answer to my question. After a long time of trying, I finally chose to post.
I did that (the Movie Maker part) and the video looks OK, but it's not what I would call HD.
I guess I have my answer. I cannot upload an HD video to YouTube and have it truly look HD. And, yes, I did change the setting in YouTube to the highest HD setting of 1080p when viewing.
I had the best success using the John Cloudman method from the link you posted. The video was much better quality on YouTube (in my opinion) with this method than the method of going to Movie Maker etc. I tried John Cloudman's Frame widtht of 1280 and Frame Height of 720 and then frame width 1920 frame width by 720. I found 1920x1080 better quality on YouTube than Mr. Cloudman's 1280x720.
I pasted in the part of the link below that I found most useful. A big thanks to John Cloudman for posting this!!
John Cloudman offers further advice:
From the Share tab, choose Personal Computer and then QuickTime. Choose the Cable Modem, DSL preset and then click the Advanced button.
From the settings window, do the following:
b Video Tab
*Video Codec: H.264
*Frame Wdith: 1280
*Frame Height: 720
*Frame Rate: 29.97
*Field Order: None
*Pixel Aspect Ratio: square
*Set Bitrate: checked
*Bitrate: 8000 kbps
b Audio Tab
*Audio Code: AAC
*Output Channels: Stereo
That should generate a .mov file that Youtube will handle correctly. You can modulate that Bitrate to reduce the amount of data size, and you can modulate the Quality number to reduce the encoding time. I wouldn't go lower than 3000 kbps for a bitrate or below 50 on Quality. Hope this helps everyone!
