There is a frame-accurate video cutter developed in Joyoshare VidiKit to support nearly all multimedia formats, such as DVDs, ISO, MPEG, MP4, MOV, MKV, M4V, MP3, ASF, AVI, 4K video, etc. Aside from lossless video cutting, it also works to convert, record, crop, rotate, apply effects and more. What's more, it offers freeware to simplify your digital life. Anyway, it's a good video toolkit to consider.
