A Few questions to do with digital files.

[jason69uk]

Ive noticed over time that my divx files seem to be worse quality than b4 it might be just me!!!! But in scenes thats filming people far away in the background they have a lot of pixelly round them.. that could be a bad rip.
If its pixelation caused from sectors would it be a different type of pixelation.. a definate noticable type that would smear the graphics all over the screen in blocks and go back to normal after itHuh?

Also ill ask u this while im here too.

After ripping, converting from avi to dvd. from ripping dvd to avi i get this wierd lines when the picture moves fast. Try this now, move your page down really fast and looking at the top there'll be a horizontal line for a split second from where the last page left off. Sometimes this happens it must be to do with memory i hope u know what i mean anyway.. Well after convertin an avi to mpg i get this line of fast movements thru out videos on the computer, what is this its like interlaced i think interlaced is loads of little 1mm lines but this isnt the prob i have here, when issuesl ike this happen the screen moves slowly because the lines are causing it to..

Whats going on here??

Also i had a prob with the external hard drive if i did have data corrupted on it would the freezes be logged in a program called divfix? i think the freezes may have been caused from unplugging it without stopping it in windows, can the corrupted data be recovered though? would deleting the file and getting it again sort the problem out? and even formatting the disc then using a program like spinrite sort it out? and no unwritten part of the drive would be corrupted would it or if it could be could that be recovered?
ive already run a program over it from the makers of the HDD's website it does a sector scan.

Sorry if these questions have been answered already i forgot the answers and cant find the topic on search.

thanks 4 all this help!!

unless you are reencoding the avi files, they cannot change quality. you may see a difference in quality between different avi files, but one file cannot degrade in quality over time.

you ripping problem could be an issue with ripping software or the settings used for rip. my guess is your software is configured incorrectly

if your HD is still readable, there is no need to format. just delete the bad file and start over

jason69uk,

Lots of questions, here's my take on them:

1 - People shouldn't download movies. That's just a blanket statement.

2 - DIVX/XVID movies (or other files) do not degrade (no techie wackos please) over time. Period. Whats happening is that you're becoming more discerning over what you're viewing. Probably a result of re-encoding movies and looking to get the best overall quality. Sorry, unless your eyesight get worse, there's no going back. In fact, this new ability to see flaws will only increase with time. Yes, its just you.

That pixelly thing in the background is what is given up to make the forground keep as much quality (to our eyes) as possible. You don't get something for nothing. Its the nature of lower bitrate vidoes and what is used to create them. Better to give more emphasis on the forground (what our eyes/brains concentrate on) than on the background.

3 - Blocks smeared over the screen. The player you're using, either the software player on your PC or the settop player for your TV, is unable to handle something in the video. For the PC, it may simply be part of the file. That is, the corruption was there in the first place. For the settop player, this is usually due to bad or incompatible media used, or, less likely the process used to create the DVDr.

4 - The weird lines you're seeing is probably interlace. When you convert from avi to dvd you should keep this. More than likely you've got a setting incorrect in your encoder. Or, the ding dong who created the video kept the interlace lines in because of improper encoding. Either way, its just a downloaded movie. You get what you pay for.

5 - Sounds like you have very little experience in dealing with the lower levels of hard drives. I'd stay away from this unless you willing to lose everything on it. If you are that curious, I would get another drive to play around with.
