downloaded Broken xvid, plays fine if run through avisynth--

[jorwex]

i downloaded the first few seasons of some unliscensed fansub for my friend with bit torrent and so far, 2 out of 35 episodes that he's seen so far are broken, from what i can tell..

the audio will continue, but itll freeze every 10th frame or so, for a good second. what's really strange is that all the programs ive looked at them with report the two clips as having 119 fps and when virtualdub opens it, the first frame it shows is a black screen with white text saying :"nothing to output Bframe decoder lag."

i can however get the file to play fine in media player classic if i use avisynth with AviSource(). it seeks just a liiiiiiiiiiiiiiiiiiitttle slower than normal though.

any ideas? i'd prefer to fix the file itself rather than running it through avisynth all the time. also, when i strip the header with tsomething like divfix, the file will play pretty well in media player classic---maybe it rebuilds the header the same way avisynth does?

if i load the avs into virtualdub and save, itll either freeze, or output REALLY slow and then if i close that and open the output, its outta synch and really choppy

any insight would be great. thanks

Sorry, afraid not. Somebody somewhere owns it. Warez.

Bad xvid encodes,dump em.

[jorwex]

but if i can get em to run through avisynth fine, isn't there a way to save em? i've looked at about 60 or so of the files and only these two are bad, so it'd be a shame to toss em. any ideas??

avisource() with AVISynth and directly opening with VirtualDub should basically have the same effect. They will both open up via VFW and ACM.

AVISynth serves the video and audio up raw, so if you resave you need to recompress if you don't want massive files.

Try playing them with mplayer or VLC.

thanks celtic_druid

is there a way to load up a file in virtualdub and record all of its attributes (ie, video & audio compression settings, resolution, etc..) and then apply those to another file to recompress? i'd like to take one of the good files and save the screwd up files with those settings after opening them with virtualdub--cuz if i do it manually, everything gets screwd up even more and outta sync, etc.. cuz (for one) the framerate of the bad files is like 120 fps but it'll play fine like that in virtualdub

any ideas? thanks

A combo of GSpot and MPEG4Modifier should give you basically all the settings needed.

GSpot will tell you resolution, framerate, codecs, bitrates, etc. MPEG4 modifier can tell you the quant matrix used, and some other usefull stuff like max bframes, etc. Both can tell you the XviD bitstream used and whether GMC, qpel or bframes were enabled.

one more thing. ive always had this problem with lame ACM...

once you click "show all formats" or however its phrased in vitualdub, not all the formats there work. and not every bitrate is there either. like the format used in the vids is 112kbps, and neither the built in windows mp3 codec nor lame acm have that one listed. the closest is 128, but theres a mono CBR one, and a stereo ABR one only too. why isnt there a stereo 112kbps CBR setting? what are people using? i thought it was lame acm..

solving that one problem would be worth this entire post...ive been wondering about that for years but never bothered to look into it!

thanks!!
