I just released Ume Movie Editor - a lossless video editor with multiple videos per project and subtitles/chapters support. I could only test it with what I had on hand (Sony FDR-AXP33 and some smartphones). Is anyone willing to check the demo and see how messed up the export results will be when used with professional cameras? [spoiler:lit]inb4 buy an ad[/spoiler:lit]
