x264/mkv -> XviD/Avi?

[therock003]

I need to try converting some mkv i have encoded with x264 codec to xvids in .avi container in order to test performance on a standalone player i own that doesnt support x264 encodings and the mkv format.

Of course though, i need the result to be the best possible, (lossy it will be of course due to re-encoding) but i want to retain bitrate resolution and picture quality as much as possible.

and you question/query is????

This is the question. Cause conversions can be done with a 1000 different software and it is not hard to find one, but i want to retain quality as much as possible. So my question is, how do i make this conversion while keeping loss at a minimum?

Try Super with the same resolution and the same bitrate as the original, with codec xvid and container avi

For starters, use with the original source instead of the .mkv. The quality will be noticeably better.

Most standalone players are constrained and can only playback 720x480 (720x576), qpel & gmc turned off. So if your source is hi-def you have to resize. They also usually choke around 5000kbps for xvid/divx so you have bitrate constraints as well. (I'm assuming this is a dvd standalone unit, not a media player)

Many programs have profiles/presets that maximize compatibility with stand alone players. If you want an easy to use program, try xvid4psp.

Ok thanx, since i aleady have SUPER that wont be too hard, but is this the best option here? I just want to be sure i get the best results doing this, but i'm cautious since this is an unsual conversion.

Anyway i guess i'll try that for now, but if there's anybody that knows of some way that gives better results, please let me know.

xvid4psp is the best. just choose the avi hardware profile.

but this is no advanced conversion. moving you.

Just tried i yesterday.Why does it take forever? The encoding rate was 2 fps and the estimated completion was 10-11 hours!Is it really that bad.

My specs were t5200 dual core and 2gb ddr2 on an asus laptop.

BTW i left the hg xvid profile, but did not make any changes. did i have to alter anything before i started with the encoding?

[poisondeathray]

You probably left the priority as idle. Change it to "normal" if you want it to make use of more CPU cycles / s

[therock003]

Nope i did change the priority to normal...

It shouldn't take that long if you are not doing any filtering.

Double check the avisynth script (avisynth=>edit filtering script). Sometimes the auto-analyze functions can introduce problems. Post the text here if you are unsure of what it means

Make sure you don't have any other unecessaary processes running, (viruses, virus scan, other apps..etc...) eating up cpu cycles

[therock003]

Nope i have not enabled any filtering, plus the computer is brand new and it ha not connected to the internet yet so there's no chance of virus either.

Dunno what's wrong though. I eve ntried AutoMKV and it even took long for the field analysis so i interrupted it before it could start encoding.

Maybe it's a VISTA thing. It came with theOS preinstalled nothing i could do.

[poisondeathray]

"brand new" usually means pre-installed with 16 kinds of software like Norton, Nero and other crappy software that bloats your system. If you didn't install it/build it yourself there's is 100% chance that many bloated apps are on the PC already.

Something is seriously wrong if you get 2fps. One of my 5 year old single core computers would get at least 5-8fps doing the same conversion

Open up taskmanager and look at the processes, see if other things aren't eating up cpu cycles

I'm assuming your mkv plays back correctly in a media player? (ie. no errors?)

You could make your own script and use vdub or megui to encode to xvid/mp3/avi (megui also has a script generator, but it might hang like automkv did). It could be as simple as 1 line, write it in notepad, and change the extension to .avs

DirectShowSource("file.mkv")

I wont have access to that computer fo another week, but i had already tried taskmanger. It was either ctrfmon or rundll32 with cpu of 45% there rest of the processes were next to zero. IT does have norton and other crap on it.
