"I have a camera that captures in .mts files, and I want to convert MTS to Apple Codec iMovie files (720p). And ultimately I want to burn all of these files to DVD’s using Roxio Toast."
Aunsoft top MTS Converter for Mac does pretty good job to transcode MTS to AIC MOV, ProRes MOV, DVCPRO MOV, etc for iMovie, FCP, QuickTime on Mac Mavericks. It solves the problem that iMovie 11 and earlier version that greatly increase file size, reduce video quality and waste a lot of time in the process. The output AIC MOV will preserve the quality almost as high as original file for you to make good quality DVDs with Roxio Toast. For creating good quality DVD my experience, if you get your AIC MOV with progressive before using it in iMovie 11, iMovie will not degrade the quality. This program allows you deinterlace bad video interlacing and remove the distracting horizontal lines with one click. If you have a camcorder like JVC GY-HM650 (record in MXF, AVCHD, H.264 MOV, and MP4), you can turn to multiple video supported iMedia Converter for Mac.
