Hello!

First of all, I should recommend to filter somehow VHS rip. Since its anime,
"hqdn3d" filter will make a lot of needed job. It will turn noise off, 
saving details.

Next, use xvid with "cartoon" switch. If raw material is not awfully 
bad, you may try to use
bitrate 1200-1500 for 640*480. Practically you will need not more than 
1000.
Even if you would rip a DVD it is good decision in 
slow-motion/panoramic/zoom-unzoom
scenes rich anime. I have seen, that VHS can produce miracles if extra 
high-grade film
were used while recording. Good 640*480 e.g. .

I would recommend this:

1st pass:
-ovc xvid -xvidencopts  
pass=1:bitrate=1000:me_quality=6:max_key_interval=500:keyframe_boost=50:kfthreshold=20:kfreduction=50:packed:max_bframes=0:bf_threshold=0:noclosed_gop:qpel:gmc:cartoon:chroma_opt:hq_ac:vhq=4:psnr 
"./v.avi" -o "/dev/null" -vf 
pp=hb/vb/hb:c/vb:c/dr,hqdn3d=4:3:10,unsharp=l7x7:0.5

2nd pass:
-ovc xvid -xvidencopts  
pass=2:bitrate=1000:me_quality=6:max_key_interval=500:keyframe_boost=50:kfthreshold=20:kfreduction=50:packed:max_bframes=0:bf_threshold=0:noclosed_gop:qpel:gmc:cartoon:chroma_opt:hq_ac:vhq=4:psnr 
"./v.avi" -o "./result.avi" -vf 
pp=hb/vb/hb:c/vb:c/dr,hqdn3d=4:3:10,unsharp=l7x7:0.5

If your target is DVD-player, these lines will produce a stream that 
possibly hangs it.
IT IS NOT SUITABLE FOR DVD-PLAYER!
If you need more help, mention your goal more clear.
