Many guys share the same bad experience that iMovie 11 and earlier version will greatly increase file size, reduce video quality and need long rendering time when transcoding 1080P/720P AVCHD footage. Personally, I usually transfer MTS to 720P Apple Codec iMoviefiles and ultimately burn all of these files to DVD's using Roxio Toast. Among multiple softwares I've tried, Aunsoft MTS Converter for Mac is best to preserve video quality without file enlargement and rendering time. For users of Panasonic DMC-ZS35, DMC-ZS40, DMC-FT1, AVCHD Lite or Canon/Sony AVCHD 2.0 camcorders, you may need this too.
For creating good quality DVD my experience, if you get your AIC MOV, progressive (p), not interlaced (i), will be much better. 2014 Best Aunsoft MTS Converter for Mac has the ability to deinterlace bad video interlacing and remove the distracting horizontal lines with one click. Meanwhile, you can freely preset AVCHD transcoding settings. For instance, you can optimize output AIC MOV as 720P, 1080P, etc. Besides, though it's a pain for many users to keep or change frame rate with other software, you can set frame rate as 23.976, 24, 25, 29.97, 30, 50, 59.94, 0r 60 with this program.
Below is a simple step to step tutorial to burn MTS video to DVD Roxio Toast. The advanced technology and the clear interface it use make the timesaving conversion process with only 4 steps.
