Hello. I,m looking for best free software to muxing-demuxing-remuxing video/audio files?
What I know:
- LosslessCut - Quick loading huge files, huge(over 100mb), focused on cutting, I get "not supported audio" with some files. Also little lagging.
- VidCutter - (Not tried it) Also huge and focused on cutting
- Avidemux - best of listed here, but chapters not supported, very slow MKV loading, huge but universal (also can do re-encoding if I want, filters etc.)
- MKVToolnix - could be the best but no preview like in Avidemux

Do You know any free program like Avidemux, with A/V tracks demuxing, joining, splitting, real-time preview, fast MKV loading, but which supports chapters like MKVToolnix, and which supports all possible formats (including rare used), which also allow to re-encode and add some basic filters if I want?
