Increasing the crf to 22 will probably get you down to 1.3-1.4 GB.
BTW I use crf=22 for low bitrate PVR recordings off TV. 20 for DVD.

DVD5 is MPEG2 compressed. x264 (MPEG4) should be at least 3x more
efficient at compressing (one third the stream size)

I might accept that size for 2 hours off a DVD9.

The quality of h264 at low bitrates is streets ahead any other video
compression (until h265) hence it's adoption on telephones where
bandwidth costs the customer money. But if you want to watch a film on a
nice big screen it's better if you spend some bits to get better quality
and larger resolution.

2 pass is the maximum required, the first pass is a test to tell the
second pass what bitrates to use.

The manual says:
For MP4 files, HandBrake will automatically use the extension M4V when
you pass-through audio (AC3), use SRT subtitles or have chapter markers
enabled.

You can simply change the file extension between .mp4 and .m4v as the
file is exactly the same.

I'm going to reply to your other post too.
