G'day Sharktooth (and others)

Thanks for all your fine work and explanations on eqm_v3lr etc. I'm looking at efficient ways to repack Digital TV (SD or PD) recordings. The XviDs are to be specifically created for a Neuston MC-500 network media player. I've tried the Neuston forums, but sweet zippo from them :(

Anyway, the input data is in what DigiTV calls DVD format, probably means MPEG-2 PS. PAL. 720x576 PAR 1.422 DAR 1.77 Interlaced.

From what I've read this would appear to be very close to PAL-DVD format .

So...I'm not really trying to squash down to fit a given nbr of CDs as the Xvids are files streamed off a hard drive to the MC-500.

With MP3-128 sound, it would seem that a total bitrate of about 1,000 gives quite good results using the eqm_v3lr matrix. Would this be in line with what you'd expect..or should I be going for a different matrix and/or rate?

I've noticed that the MC-500 seems to skip frames unless you enable a packed bitstream. Does packing the stream lead you to suggest I should be trying another matrix?

Also I currently use VirtualdubMPEG2, resized via inbuilt filter to 576x324 Lanc, 2 pass, AS @ L5, ( B-VOPS 2 / 1.5 / 1.00) with [ Adap Q, Interlaced Enc, QPEL, GMC] all off, if that helps. QPEL and GMC are not supported under the MC-500. If any of these should be changed, pls let me know.

Thanks a lot.

Well, you can try to enable AQ (and Trellis?) and look at the results. The other settings seem to be fine.
However, if you have time for experiments i can suggest you to rise the resolution (or not resize the original stream) and encode it with EQM V3ULR at the same bitrate (1000kbps).
Compare the encodes and choose the one which looks better.

Excellent. Thanks for that. Happy to report that the media player can cope with AQ and Trellis.

Tried 592x336 instead of 576x320. Also used your suggested EQM V3ULR mtx with the same bitrate. Am very happy with the results and will stick with these as my defaults.

Just wondering, are the numbers actually displayed for EQM V3ULR http://forum.doom9.org/showthread.php?s=&threadid=83125 the same as those in the download file http://www.aziendeassociate.com/cqm/eqm_v3ulr_rev3.xcm ?

Thanks

EQM V3ULR mtx is very good I use it for 2.2 gig xvid full dvd res rips
output is very close to the real dvd.. No microblocking at all.. the EQM V3ULR works good very good in all bitrates
