Where do we confuse those two? We specifically talked of codecs and =E2=80=9Ccontain=E2=80=9D. > .ts is a container format, h264 is a codec.

You say you don=E2=80=99t understand it, but then= explain it. TS is like AVI and MKV: a file structure for the payload data. And payload data can be all kinds of stuff, from ASS plaintext subtitles, over opus audio to mpeg2 or h264 video. > Incidentally, sticking this stuff in a .tar is probably okay - that's just > another container, but sticking it in a .tar.gz is not, the gz is your co= dec > and will make the file BIGGER in all probability. Tar does not compress, it simply puts all inputs in a 1:1 stream. It does add some metadata (filename and so on). Packers reduce data volume by increasing information-per-byte. So if the total information stays the same (for lossless coding), the number of bytes decreases. Encoded video data ideally has even entropy. It is indistinguishable from random noise. That= =E2=80=99s why compressing it again does not yield anything, or even adds some volume again. --=20 Gr=C3=BC=C3=9Fe | Greetings | Salut | Qapla=E2=80=99 Please do not share anything from, with or about me on any social network. =E2=80=9CMankind must put an end to war or war will put an end to mankind.= =E2=80=9D =E2=80=93 John F.
