DVD interlaced at an angle

..or at least it looks a bit like that. I recently bought the remastered version of Mr. Bean on DVD. Two of the episodes had parts, that looked rather weird, like interlacing, only at an angle. Here's some example frames, it's especially visible at the glass of wieners: It may not look like too much, but the error moves sideways with every frame, which makes it very annoying when upscaled to a FullHD Screen. Has anybody seen the problem before and how can I get rid of it? Thx in advance. (Also, am I allowed to upload a short sample clip here? It is copyrighted material after all and I don't want to break the board rules)

Probably you are talking about the bad dot crawl. Look for dot crawl removers, such as CheckMate. You can upload a small sample under fair use. Use DGSplit to cut the VOB itself (say 50 MB), upload to mediafire.com, and post the link here.

Bad dot crawl is notoriously difficult to correct. Don't hope for miracles. Hopefully our members will help you find something that at least improves things somewhat. Good luck with it. I will move this to Avisynth Usage as it will likely attract more attention there.

Unfortunately, like most other BBC features, Mr Bean was shot on tape, not on film. The crawling dots are part of the taped video (original) and not obtained via digitisation or other post processing. I have the "old" version (it doesn't mention Remastered - whether it's the same or not I can't tell) and, while I am critical about image quality, I was not disturbed too much about these artifacts. I was more disturbed by the lack of dynamics in image, "tipically tape" :)

Mr Bean was ITV. The BBC would have used their transform PAL decoder for the composite to component conversion, which would have removed the vast majority of the dot crawl. Cheers, David.

I just noticed it on the two episodes while watching, as it was particularly visible there. The clip is from 'Do-It-Yourself Mr Bean' (DVD2/Ep10), the other one is 'Back to School Mr Bean' (DVD3/Ep11). I'm not sure, if there's dot crawl in other episodes. I may simply not have seen it, like it didn't faze Ghitulescu when watching the non-remastered version. I also noticed some bad frames and tried to fix them in photoshop, could upload the results if you're interested. (Two frames from Ep3 'The Curse of Mr Bean' and 7 in the Special 'The Library') Apart from that, I still don't know how to get rid of the dot crawl at least to a point, where you don't notice it when watching. (In order to push this discussion btt :p)

I checked my version. I played the original disc (from Universal, Germany edition) on a Pioneer DV-646A connected via SCART/FBAS on a Sony Trinitron 21". It's a pure analogue setup (matching its 4:3 DAR, too). I could not see any dot crawl. Yes, there have been artifacts, mostly from MPEG compression (around edges), nothing serious, anyway. And of course the analogue noise, which seemed filtered in the Remastered edition.

Yeah, I wouldn't have noticed it on the old version either, if I wouldn't have searched for it, even on my pure digital setup (mpc-hc with internal filters on my htpc connected to an 32" LCD over HDMI). In case that wasn't clear, the comparision frames were only to show, that the dot crawl is there, just not as obvious.

I noticed a weird thing in The Trouble with Mr Bean. For two shots (after the electric shaver incident) it drops from 50i to 25p-in-50i. It's the same where this clip appears in the broadcast version of The Best of Mr Bean, so it must be like that on the master. Some mistake in editing probably. There is rainbowing (we usually call it cross-colour) throughout on moving sharp edges, but nothing noticable on other things when watched in the same way as Ghitulescu. Given what a poorly decoded PAL composite signal looks like, this was already decoded pretty well. the film inserts look comparatively poor, but it's always like that in UK shows. Pity the folks who "remastered" it couldn't have fixed the bad frames. Don't expect faults like that on relatively recent shows (considering there's BBC colour video from the 1970s that still plays perfectly!). I don't think I'd have the patience to go through fixing it - I just want to enjoy the comedy, and it spoils it watching it with a "video restoration" mindset. I've spoilt a few CDs for myself by spending hours fixing them, and then not been able to enjoy the music for years after. Cheers, David.

Well, I'll try to capture the corresponding frames from my version. It appears that in your captures, dot crawl appears at edges of yellow-to-brown surfaces. It is not noticeable on analogue setups, like mine. I'll check it next on my pure digital setup (pioneer to pioneer via HDMI). I do not watch movies on laptops or computers.
