I have had a few threads where I asked about my 1920x1080p 59.94fps video and the problems (stuttering video) when I tried to just author and burn to bluray, because bluray can't handle 1080p 59.94fps video.

I have now had success with these 3 steps and the video quality (now 720P 59.94fps) is visibly no worse than the 1080p 59.94fps.
Here is my 3 successful steps:
1. Using Freemake Video Converter, I pull my video files over to Freemake. Next I use, to Sony, title Custom to convert my video files to 1280 x 720p 59.94fps, H.264 video codec, bitrate (Kbps) of 26000. Audio codec of AAC, 48000 Hz, auto bitrate. I join my files together (but that is not necessary). I then use 1-pass encoding (high speed) and convert!
2. Then I take that converted Mp4 video to MultiAVCHD and author to blu-ray.
3. Then I burn the files using Imgburn.

The quality is just as good as the original 1080p 59.94fps video from my camcorder, except now it's on a easy to view blu-ray for my family to pop in and see anytime.

I really like Freemake and Multiavchd. It takes about 2-3hrs to encode a 6GB video. Multiavchd only took 1hr to author my 21GB video.
