Anyone notice some weird VHS-ey waving dots that are shown on episodes that were made before 2002. Not the flashing cue dots that appear in season 1, due to cel animation, I'm talking about weird wavy lines or dots on bright objects. These only appear on TV, not DVD, since the DVD episodes are remastered. 

 

 

Look at the orange flower, and you'll know what I'm talking about. This isn't only in spongebob, this weird effect is seen in a lot of older shows that were made prior to 2002 or 2003.

Yeah, I noticed this too. Some non-HD episodes (even up to at least Season 5) have a weird moving dot right near the talking shark thing in the intro. Noticed it in at least Procrastination and 20000 Patties Under the Sea. At first, I just assumed it was one of the many things messed up with the Procrastination airings, but then I noticed it in 20000 Patties Under the Sea

I think it’s because Season 2-8 were drawn on 480p screens, yet some parts were digitally messed up to accomodate 480i TV screens. Either way, I find this to look nicer due to the more vivid colours and a slightly higher refresh rate, but I can see why it’d be distracting.

Nick should try to make the episodes in HD like CN does with a lot of their old programming (such as Teen Titans, old Scooby-Doo Movies, and that Billy and Mandy special they aired recently in October).

I actually mentioned this in a recent topic I made. Is it possible for Nick to fix this? They fixed it on DVD, so why not TV? Speaking of which, SpongeBob is actually yellow on TV, and if Nick fixes that problem you're stating, it would be on par, if not better, than the DVD's! In my opinion at least. :)


EDIT: While I do find the wavy dots to be distracting, I still find the quality better than most other rips of these episodes, and plus, it adds nostalgia value :)

They probably don't improve the quality like they do with the DVDs.

It's a distortion based on the analog source of the episodes, if I recall correctly (has something to do with the deinterlacing method) - lots of older shows face the issue, as you said.

Also, kind of weird. In some episodes like "Have You Seen This Snail?", some scenes look perfectly normal, but then it cuts to another and it looks like it was from a VHS or something.

Yeah, like the scene where Spongebob was crying on the kitchen, it looked all VHS-ey, but then next thing you know, when Gary is with the old lady, it's back to normal.

I think it’s because Season 2-8 were drawn on 480p screens, yet some parts were digitally messed up to accomodate 480i TV screens. Either way, I find this to look nicer due to the more vivid colours and a slightly higher refresh rate, but I can see why it’d be distracting.

 

This issue never occured in seasons 6-8, all the studio equipment went digital by then. I think after season 5 or so, they stopped producing episodes on master tapes, and switched to having the episodes air on tv, by using digital computer files.

Something similar happens in the digitally colored seasons of dexter's lab, one scene looks all new and clear, then next thing you know the lines get wavy and it looks all VHS-ey.

Yet Nickelodeon hates CN and wants nothing to do with them.

If that's true than why would advertise TTG's 100th episode or whatever that was? I remember them advertising that a while back and I never understood why. I remember seeing Gumball and We Bare Bears advertisments too.

 

Can't hate them too much if they're willing to advertise their shows on occasion.

Two episodes from season four on DVDs have VHS quality through and through - Best Frenemies and Bummer Vacation and I always wondered why, because on TV those episodes looked perfectly normal if not better.

No it wasn't I remember seeing the episodes in their original airing. Then again when the episodes first aired I watched them on an older tube based tv.


Bummer Vacaction still has that VHS effect on certain airings on Nick

It's not Nickelodeon's choicr airing ads for other networks. Your cable/sattellite provider inserts ads like those for a minute (like for me DirecTV airs Nickelodeon promos on CN). It's very hard to explain why TV does that but I hope I cleared things up :P

last time i checked theyre besties on twitter

Now come to think of it, whenever I watch tv on older CRT TVs, It actually does have the weird VHS effect, unless I'm using component.

That is very interesting. I think that's an older rip of the episode SGOD, because I saw the episode air on my TV a few days ago, and while it had the VHS effect, it wasn't as noticeable as it was on Nickelodeon's website.

VHS tapes and tapes in general do not use pixels, in fact old CRT monitors did not either. They used horizontal lines behind something called a shadow mask to display the picture. So that is what the effect looks like. But I doubt this is the main cause, that is probably interlacing. Every wonder what the "p" after 720p or 1080p means? It doesn't mean pixels, it means progressive. What television programs are transmitted as is an interlaced signal (like 720i or 1080i). This means that the signal is spilt into horizontal lines (like CRTs) and is transmitted with usually every other line, with the image usually stretched out. This is done to save space in the transmission. This creates something called visual artifacts on the screen, something that may be more noticeable on a television broadcast as most are done using interlacing methods. Now the effect appearing on the DVDs and on Nick.com may have to do with them using the interlaced video, on them storing the footage on tapes that use horizontal scan lines to display images. I hope this clears up any confusion!
