I archive NTSC video in MPEG-2 at roughly 30 Mbps.
That way, there are no worries about future codecs being too good for
the archives.

Whilst MPEG-2 for broadcast purposes will be in the 3-5Mbps range,
MPEG-2
for archival/storage will be at a significantly higher bitrate. If
you're
storing at high bitrate MPEG-2, the transcoding to MPEG-4 will have
much
better results than if you transcoded from broadcast quality MPEG-2.
