Hi. There are two things to look at. K-lite Codec pack and also Handbrake video converter software. #### I recommend Handbrake converter because I use it often for turning m2ts files from one of my cameras to MP4. It will convert most codecs like MKV/MOV to most codecs H.264 AND H.265. I also use it to convert different frame rates to other. For example, I have one camera that does 25 fps mp4, one that does 24 mts2, one that does 30 fps MOV and another that does 50 mp4. I use a drop frame algorithm in the Handbrake program to convert all frame rates to 24 fps to sort out sync issues. Hope that helps you.
