Extensive XVid artifacting -- a B&W issue?
Hi,
I'm trying to encode a black-and-white movie using XVid, and I'm getting severe artifacting (to the point where certain shots 'repeat' themselves several times, as the file catches up to itself). Is this a B&W issue, or should that not matter? My settings line up with many of the recommendations in the export settings thread. -AzS |

File's pretty big (even about 20 seconds is nearly 25 mb) -- filesize limit here is 300k for a .zip file...
The artifacts happen primarily on movement... I'm encoding a 720x720 square pixel video (yes, it's a weird size) Profile is unrestricted, as a result. I'm encoding "single pass" (other encoding types don't work, for some reason -- I get error messages). Target Quantizer is 1 for maximum quality. Quality preset is "General Purpose", though I'm going to try the "Real Time" preset now, too... -AzS |

Nut sure what the region is, though I imagine it's region 1. The movie, though, is from the late 1930s, so I doubt there are multiple angles at work...
I disabled BVOP (not sure what it is), and I'm getting a somewhat smoother picture, but there's still a lot of artifacting (the blocks are smaller, though...) -AzS |

If you have the original single disc version, play it and you'll note that the film is of poor quality - and this probably leads to the issue you've described.
On the other hand, if you the 2 disc "Collectors' Edition", you have a wonderfully cleaned up version of the B&W film, that should give you the problems you've described, plus a colorized version... |

Old thread but thanks is in order to Setarip_old for above comment.
I bought a copy of PAL DVD "It's A Wonderful Life" on Wednesday, and as it was a pretty lousy conversion I did search on it and found this thread. Having seen Setarip_Old comment Quote:
So, yesterday I bought the two disk Platinum Editon and is much better B&W version + colorised verion is done from that better restored B&W. The lousy version also has two documentaries not found on the Platinum version, so I guess I'm happy to keep that one too. Here, link to Cex/Webuy (In the UK, 2nd user DVD+Bluray + I.T. related stuff):- https://uk.webuy.com/search?stext=it...list&inStock=1 The lousy one is the green tinted one shown first [at time of posting - if not shown, then untick "In Stock Only" to show items no longer in stock]. Here, 3 images of lousy, restored B&W and colorized. And again thanks, SO. EDIT: The colorized one that I have has the title over a blue background but the colorized cover @ above link one is presumably the same (has both B&W and color). The Lousy one seems to have been converted from NTSC version, rather than directly from the film. EDIT: Looks like there is a lousy version + a good verion of the BluRay too at above link. EDIT: From IMDB, https://www.imdb.com/title/tt0038650...ef_=tt_trv_alt Quote:
EDIT: This is exactly the one I have, (there seems to be quite a selection of DVD covers/releases):- https://www.amazon.co.uk/Its-Wonderf.../dp/B01LQ7RBTI Runtime 2:05:29.32 secs PAL speedup. [lousy one 2:10:13.56 PAL] EDIT: Also got me a restored Anniversary edition of The Wizard of Oz, interesting documentary and good restoration job.
