Posted by: i4004 Nov 17 2004, 08:02 PM

i've had some success here, so i thought i should share:
i was succesfull in transporting .wmv streams to .avi by mencoder usage.

i wasn't satisfied with the fact that i didn't really find a player that could slow down my wmv streams, and while i was searching for something (on the web) i've run into some hint that this could be done ( http://zebra.fh-weingarten.de/~maxi/html/transcode-users/2004-03/msg00342.html although this sample is reencoding wmv to mpeg4 ), so i gave it a try, few cmd lines i tried;

CODE

mencoder D:Videoexperimentalw.wmv -nosound -ovc copy -ofps 25 -o D:Videoexperimental1.avi

mencoder D:Videoexperimental2.wmv -oac copy -ovc copy -ofps 25 -o D:Videoexperimental1.avi

(if you'll use mencoder or mplayer, here's a brief .bat file that should make your life easier:

CODE

cd D:VideoAVISYNTH252 scripts+filters_
cmd

put path to mplayer or mencoder after 'cd'.
save this as (for example) "cmd_launcher.bat" and when you wanna use mplayer or mencoder click on it, and it's ready.)

i have tried this with wmv7 and wmv9 (both with wma9 sound) and all worked well.
wmv9.avi is recognized as "ms-wmv9" (ie same as files made with vcm9) , and wmv7.avi is "fvfw" to windows (this is .avi with 'wmv1' fourCC) and they are decoded via 'wmvideo decoder dmo'.
(if you want, you can decode wmv7 and wmv8 via ffdshow too...my version of ffdshow says wmv8 decoding is 'incomplete, though.)
if you decided to leave sound too, it works too!
(.avi sound is then decoded via wmaudio (or wmspeech (

) decoder dmo ).
wmplayer6.4 can't decode the sound of such files, but all other players i tried can.
the sound wasn't really my objective as sound can't really be perfectly synced in slow motion anyway (in any .avi files).

now i can use this to convert wmv files i wanna slow down on playback.

on winxp you shouldn't have such troubles in the first place, as wmplayer10 seems to have playback speed control. (wmplayer10 is available for xp only)
but i won't use "bob" (

) just because there is no wmplayer10 for win2k.
you can use it on winxp too if you think wmplayer10 is ugly, or something.

so there cyberman, now it can do anything avi can (as it is .avi

)

Just gotta say, the playback speed control in WMP10 is a hoot. It slows the audio too, but doesn't affect the pitch, so it sounds like everyone is just talking r.e.a.l.l.y. r..e..a..l..l..y.. s...l...o...w...

Makes smart people sound retarded. ROTFL

muxing in graphedit doesnt work?

Posted by: i4004 Nov 18 2004, 12:57 AM

i'm not a big fan of graphedit.
(although, you may enclose an image that shows the graph ; perhaps it will be of some use too)

but ok, people, get this; this even works for .mp4 files (mpeg4 video inside).
i just converted one "computer chronicles" episode.
yeah, sound had to be decompressed (from aac to pcm) but what the hell, it works!

CODE

mencoder D:Videoexperimental1.mp4 -oac pcm -ovc copy -ofps 29.97 -o D:Videoexperimental1.avi

the seeking is problematic ie. very slow (transferred stream has 0 keyframes in .avi), but...what the hell it works (

) , and i'm watching cc episodes without jumping on the timeline anyway. (if seeking is needed, one can 'rederive kf flags' via vdub and ffvfw codec, and save via "direct stream copy" )
so now i don't even need to use mplayer's command line (or them silly 'launchers') to play .mp4 files.
hoooray!

Hi,

Sorry, if I mension different program in here.
But there is easier way and you happen to use same codec, here is answer.
Newer version Dr.Divx 1.6 will convert WMV to AVI automatically without much cry in same same resolution (video and audio).
ASF conversion will be problem even if you do ASF-WMV-AVI (vertualdub can't do anything anyway, problrm is codec).

Bad part is they only use;
1. Divx codec only.
2. Resolution is Limited to 720 x xxx (DV max conversion by Premere Pro) unless use HD certified option that is not compatible to any Divx player currently available even if certified by DivX. No one is certified HD resolution yet. Well there is only one (AVeL LinkPlayer 2) $ 249.00 and play upto 1280 x 720 in cerfied level but goes upto 2048 x 1532. Play WMV as well
3. Quality is not as good as Xvid even if double resolution (well, you use vertualdub will not make any different, Dr. DivX is just automated. They may paid to M$ to get that WMV shxx.
4. Maximum FPS is limited to 4000 as DivX max compair to Xvid 8000 and WMV quality is as good as Xvid but they are not certified by nay player but one.
5. Xvid speed is lot fater than Dvix but Dr. Divx, you never have to attended encoding. You encode 10 of them at same time before go to sleep, it will be done next day:-) Let me know, if is there any automated 2 pass Xvid version in one shot like Dr. Dvix.

Well, I messioned my home video conversion to AVI in XviD was impossible because bottom (almost 50%) part of conversion was blockey (all of bottom part is fill by moving block and very big size).
Ooops, not in PC play since I can load 1 million codec but my Divx and Xivd Player (Neuston 1201 and Philips 642/37) are not. DVD conversion to AVI in XviD was very good but, home video (Mini DV) conversion was bad like explain above.
I finally converted to 3000 - 4000 FPS to make better quality but still 1500 - 3000 in Xvid is lot better:-(

Anyway, let you know I did try evey filter in vertualdub and lots or commercially available filter.

I will go whatever easier way, and quality way.
If Dr. DivX let me use choise of codec and more option, I will choose them before any others. Well, they are not free but it still well worth 20 $.

Hopely vertualdub have 2 pass automated option.
Well, if I am as smart as your guys are I could make scription to do that or something but 99% we are dumb:-(

Hope it help.

i was talking about putting video from one container to another, not about re-encoding options (plenty of those exist too).

I found a way to convert wmv using AVISYNTH.
But there is no sound. I'm very new to avisynth
Anyone know how to get the audio? thanks..

convert.avs

directshowsource("E:test.wmv",25)

Sorry if this constitutes a double post, but this is appropriate info.

Hands-Down the Easiest, Cheapest, and GUIest Way to Transcode from Wmv to Avi

1. Drag and drop a .wmv file into TMPGEnc
2. File -> Output to File -> AVI File
3. Configure as necessary

Blazing fast! No cmd functions! No coding necessary! n00b friendly!

Posted by: stephanV Jan 5 2005, 05:57 PM

i found a rather weird way of doing it.

1. use graphedit to mux the video in Matroska (without decoders), demux the audio stream with a wav dest filter(no decoder again).
2 open the file in VirtualDubMod, add the audio stream to the strams list and save as AVI

c'est ca

you keep both audio and video this way. i tried it with a CBR WMA stream, i dont think VBR will work but
ill give it a go.

Posted by: stephanV Jan 7 2005, 06:03 PM

VBR doesnt work... but CBR WMA9 Pro does

goes for you too.

Forgive me. I've resisted using AVISYNTH for the longest due to fear of the unknown. I suppose I have not yet experienced the functionality of a different wrapper vs. a complete transcode (with the obvious exception of saving of HDD space).

But I am now that much closer to actually buckling down and joining the 21st century's best practices by becoming familiar with AVISYNTH.

Posted by: stephanV Jan 12 2005, 03:37 PM

AVIsynth will always cause you to re-encode... so if you want to remux, sue Ivo's method or my method (my method is of course far superiour

), although his is faster.

avisynth is more of a 15century gutenberg-interface(simillar to mencoder), but that makes them powerfull.

the stuff stephan just said is probably true; i dunno, i don't use matroska, but no reason to doubt his words.

Posted by: stephanV Jan 13 2005, 05:07 PM

its alll good, it shouldnt matter in principle.

im just not a big of fan of CLI thingies

Posted by: i4004 Jan 13 2005, 07:28 PM

graphedit is worse than any CLI i saw.

Posted by: stephanV Jan 13 2005, 08:06 PM

each to his own

graphedit is not so bad when you get used to it, although it is the last thing id try (well, before a cli tool

)

i already saw it before... had to read a very long HTML doc before i actually could do something with it...

i just want things to click on

i just spent 5minutes troubleshooting the avs script whose "only" problem was the line-feed on the wrong spot. word-wrap problem, so to say.

CODE

AviSource("D:VideorawstuffS_T__R_I_p000.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p001.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p002.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p003.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p004.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p005.00.avi") ++ aviSource("D:VideorawstuffS_T__R_I_p006.00.avi") ++ AviSource("D:VideorawstuffS_T__R_I_p007.00.avi") # ++ AviSource("D:VideorawstuffM6_008.00.avi") ++ AviSource("D:VideorawstuffM6_009.00.avi") ++ AviSource("D:Videorawstuffperf_11.00.avi") ++ #AviSource("D:Videorawstuffperf_12.00.avi") ++ #AviSource("D:Videorawstuffperf_13.00.avi") ++ #AviSource("D:Videorawstuffperf_14.00.avi")

this cannot happen if you have gui.
you win.

Posted by: stephanV Jan 14 2005, 12:29 AM

well notepad (++) is not that bad though... its the CMD i dislike

and doing all this scripting on a GUI...
