TS Muxer might work, but it can get glitchy very easily in my experience. I got myself TMPGEnc Smart Renderer for this type of stuff, works a charm - can even repair glitchy files by running them through it sometimes. It will also immediately show you if a lossless combination is possible or not - primarily depends on resolution and framerate of course, but there are lots of under-the-hood factors too. Someone else also mentioned VideoRedo as being able to do it well too.
