[mythtv-users] mencoder and NBC 1080i

[Mike Rosack]

I've been encoding all of my 1080i HD recordings to x264 (1-pass) for
a while now using the following command line:

mencoder "$1" -oac copy -ovc x264 -vf pullup,softskip,scale=1280:720
-ofps 24000/1001 -x264encopts
bitrate=2250:subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid:weight_b
-o "$2"

This works great for most of my recordings, but for a small percentage
I get a constant stream of "1 duplicate frame(s)!" errors from
mencoder.  The resulting output looks pretty bad, extremely stuttery
and almost unwatchable.

I'm not 100% sure, but I think that I've only ever seen this happen
with NBC shows, so maybe it has something to do with my local NBC
affiliate.  Has anyone else seen this happen?  Am I missing something
in my mencoder command line?


Thanks,

Mike Rosack
