"Just bought Canon HF S10 last week. Of course I like it. But I've realized that it records files with MTS extension. Before I’ve used mostly free Handbrake for converting general video into MP4 video, because it’s free. Now the thing is somehow Handbrake doesn't recognize about 30% of my MTS files but give "No Valid Source Found". Can anyone help me reach another best way to convert .MTS files to .MP4(H.264 video) that i am able to import them to Premiere (which is not possible with MTS nor is it in final cut pro)."

MTS format is a high-definition MPEG, AVC, H.264 transport stream video format, which is widely used by HD camcorders. The AVCHD(*.MTS) format has become a very popular format for sharing movies because it works well with retaining the quality of high definition movies. It’s a popular demand to convert MTS to MP4 these days because MP4 format is widely supported. In this guide, I’m going to share with you the best way to do the conversion on Mac and Windows without quality loss.
