Got me Half Way! I’ll take it! And for FREE!
I had 6 .MTS files that I changed the extension to .m4v and couldn’t change back. All the other converters made the quality horrible or wanted me to pay $60 to buy the software, I only had these 6 videos to convert. So I tired this FREE Converter Video app and converted the .mp4 video- which was VERY slow and choppy BUT I was then able to open this video in iMovie (which I wasn’t able to with the .MTS or .m4v file). So I then exported the .mp4 video from iMovie to a perfect quality .m4v. SUCCESS!
