I'll tell you what I hate. .flv
Why not keep .avi or .mkv? Heck, the only thing I hate worse is .mp4

How is it courteous, it just adds an extra step for nothing and a bunch of files to deal with for nothing, and slows down transfers. (slower to transfer a bunch of small files than one big one) Just leave the file alone, it's already 1 file. If it's multiple files, then zip it as 1 file. Though unless it's text based data there's no reason to compress anyway.

It's about robustness. news posts get damaged/deleted all the time, smaller files = easier recovery.

Just use p7zip already.

I'm just glad when people use compressed formats at all, though in my case, it's people sending either BMP files or TXT files.

Nothing like waiting for an e-mailed 2MB BMP screenshot that could have been a 40kB PNG, or a 30MB TXT file that'd compress down to 2MB.
I really like that Windows 7's Paint program defaults to PNG for new saved files.

Pars are courteous because rars can become corrupted. Especially when they are transfered across multiple drives spread out over long distances.

But say 1 guy does it and another guy does it, but one of his files is corrupted, how am I going to obtain that file anyway, one guy might have compressed it differently than the other, so it's not like the files will be interchangeable. I still have to redownload the whole thing to get the file and if it's corrupted from the get go I'm screwed anyway. Typically these multi file rars are inside a single torrent or a single zip file so it defeats that purpose anyway.

And yeah I absolutely hate .flv as well. You can't do anything with that, like if you need to take a clip and put it in an editor or reencode or w/e.

.mp4 is not that bad anymore, seems vlc and xbmc can play it fine now, but when it first came out it was annoying.

And yeah I LOL at people who send email images in BMP format. At least use uncompressed jpg if you are scared to alter the quality, or PNG. The best is when they take a screenshot to send to the help desk, paste it in word, print it, then do scan to email. I've actually seen that lol.

...that is what parchive files are for... recovery of segments... They are found in a torrent because the seeder just used the same set that is meant for nntp.


You have never used multipar?

I just hate the compression. If something goes the slightest bit wrong you get that funny "4 pixels are different colors but move in a blob." Do you know what I mean?

OK, so you use *n*x OSes, but are oblivious to PAR and FFMPEG and mplayer? Seriously? FLV isn't directly supported by most editors, but you can work around it easily enough.

You can lose most or all of the file with very little data loss in the file, and yet it still remains larger than an MKV. I've never had a problem playing them, personally, but it's far from a good general format, IMO. Like ExFAT, its blessings from IP holders are what make it common, not its merits.

It's convenient for some users. What if they're not used to stable internet connections? What if your plan includes file hosts with size limits? Or, what if you want to recover files? It's more convenient to recreate a whole file than to try to recover a partial file and work from there, because the recovery will take longer than just running a parity-based recovery. If more than one file got damaged, then those partial recoveries will likely yield a correct working file set in the end, too.

Now, compressing them is just stupid, but splitting them isn't. If you can't extract them, then either they were intentionally corrupted, or something went wrong.

Having suffered corruption of backups between making them and needing them, I, like a few others here, I also pack and par any long-term backups.

Though, while I get splitting files, I don't quite get why people still use RAR...

I love it when people rant about an issue regarding computer or technology related topics and come to find out they obviously lack the higher brain functions to understand why their rant is borderline ignorant or downright idiotic.

I love proper releases with RAR files. I could download the RARs that were still available on a newsgroup server with low retention, then get the missing pieces from a torrent (while seeding the torrent with the RAR files I had already downloaded). I could revive a dead swarm this way when none of the peers had certain parts.

My peeve was when some asshole would take a proper RAR release and ZIP UP THE FILES into a single archive before making the torrent. Then I couldn't contribute using the files I had. Pointless.

I usually download legal / obscure things that don't get a lot of steady seeds.

Well I was trying to think of... Ummm... Legitimate purposes.

Par files are legitimate. If you're archiving your own photos (legitimate copying) it doesn't hurt to create some par files. Hard drives get corrupted and optical media goes bad sooner than it's suppose to.

A release group puts it out with a .NFO file describing the release contents and specific filenames. You get the missing / corrupted files "filled" by downloading them through an alternate source that is sharing the same release.

Huh? What does this have to do with mplayer and ffmpeg? I never even said anything about those.

I've never seen this, except for stuff loaded on free hosting sites that allow a max size per file that is smaller than the full video, but nobody needs those.

It wasn't a trend established on those sites, it was just practical to continue doing it there.

It started with newsgroups and is readily used on torrents. As mentioned earlier, it allows for consistency of a specific "release", regardless of your download source. Individual parts can be downloaded from anywhere, which comes in handy for so many different reasons. So long as all the original parts of the release are together, and there is no corruption, the media will be intact.

Even better, some modern media players don't even need you to extract the file from the parts; you can point to the main part file and the media will play.

There's your problem right there: you assume that the ones doing this are the ones sharing it. No. The ones doing it are the ones releasing it for everyone else to share. Duplicate, modified, or extracted releases are supposed to be rejected from the scene unless there was a problem with the original and it gets "nuked."

Sharing an extracted file is the essence of n00b, with or without the release nfo.

Nobody working in IT can be this clueless.

I think RS is putting together an alibi for his inevitable disappearance by the RIAA and MPAA black helicopters.

Just because I think something is retarded does not mean I don't know why it's done. I just don't think there's a point to it, it just adds an extra step and requires me to download a program, when they could have just shared the video file normally. This is equivalent to pasting a screenshot in Word, printing it, then faxing it to the help desk, when the screenshot could have just been sent directly in an email.

The corruption reason is silly, TCP/IP takes care of corruption as it will retransmit any data that did not make it properly. If the file is corrupted right at the source then no amount of splitting will fix that.

The point was mentioned in this thread probably 10 times already. You thought it was about compression but it's not. It's about having parity bits available.

What's generally the quickest and easiest way to deal with not being able to get to video or audio in a FLV? FFMPEG or mplayer from the command line, depending on your tastes. A couple GUIS can do it, like VLC, but they're harder to work than the terminal programs.
