Well, you are getting a lot of advice; let me offer more. The
suggestion to use DV is probably the best suggestion so far because it
is only 5:1 slightly lossy, very well understood, and very
interoperable (no generic container required). Moreover, the ffmpeg
-target option supports it to make it very easy:

ffmpeg -i in.vob -target pal-dv out.dv

Alternatively, if you do not want any further loss of quality and are
willing to make large files (2:1 compression over uncompressed), try
the "Lossless Matroska" preset I added to Kdenlive's Transcode.
Right-click the clip in the Project Tree, and choose it.
