with bit torrent no one else was willing to leave there PC on for 2 weeks straight so I was the only seed.
The projected file size will be about 700Mb, any Idea's

I'm not sure how Gmail would work. I'm sure it doesn't allow more than one user to log on to a single account. Then there is a 10meg attachment size limit, so Bytor would have to send 70 emails to the account.
I suppose everybody could sign up to Gmail and bytor would send everybody the 70 emails but that's just sounds way too difficult. I'd say it'll have to be a ftp/web server or BitTorrent...
BiTorrent can be used if people will stay and seed. If people just leech and disappear then it wont work. I'll be happy to keep seeding for a while.

No there would be ONE gmail account where people would log in turn. The video could be split in 70 files in RAR and sent to this account.
Or we could send it to a newsgroup but most people would have to sign up for a newsgroup provider.

I am doing some tests and the final file size in unknown at this point. The problem is resolution and bit rate. In order to keep quality up I need to keep the resolution higher then even DVD's, because the action (changing pixels) happens in a small percentage of the screen at a time. Think of how small a worm is in the screen compared to how big the main action is in a movie. It is like having to read a license plate on a car when the camera is focused on an actor crossing the street 1 block in front.
The logical solution is to lower the bit rate but the bit rate when using VBR skyrockets when the viewing area is changed. (using select worms, jetpack.exc.)
Encoding a video game is a lot more demanding then movies. I do however have the GOP structure nailed down. I have a lot of experience and knowledge in digital video encoding so at least we have the right man working on it :-) my target is under 1 gig for 90 Min
Actually recording the game may be a problem if I am playing in the finals. The output file size before encoding depends on the speed of the PC U are recording with.
If I am speculating the game I can record the game on my main PC wich is fast enough to compress the file so a 90 min game would only be about 30 gig- no problem.
But if I am playing in the game I would have to use my laptop to record the game and it only has a Pentium 4 @2.4GHz... Not real fast so the output file for the same game would be 100 Gig. The laptop's hard drive is not anywhere near big enough to store 100 Gig so it would have to write the file across my network to one of my Main PC's hard drives. The problem there is trying to write 1.2Gig/Min and be sending and receiving data over the Internet would be a stretch for my router.
Rest assured I will get it done, this is just an update of what obstacles I am working to get around right now

I'm not sure if this is going to be of any help, but here's a link to a codec that's optimized for screen capture. It should generate better quality and smaller files than what you would get with an encoder geared towards movies; it's also lossless, which is what we really need, and I think it doesn't need an extremely powerful machine either - 2.4 MHz might be just enough. www.techsmith.com/products/studio/codec.aspOn the issue of writing uncompressed video over the network, indeed, 1.2 GB/min means 20 MB/s, which is more than what 100 Mb/s Ethernet can handle. But Gigabit Ethernet is getting really cheap these days . Anyway, don't worry about the Internet traffic - it's nothing compared to these numbers. On the other hand, you might want to try another solution instead of Ethernet: an USB 2.0 or a FireWire link; either one of those provide 400 Mb/s, which means roughly 40 MB/s net throughput - should be enough. Windows XP even installs network drivers by default on top of any FireWire link it finds, and there are solutions for USB as well.

Yes I know about TSCC, I have looked into about all formats. Have U ever herd the saying "crap in = crap out" No PC is fast enough to do "real time" video encoding at the quality we need and get maximum compression ratio allowable buy the format. When U record a digital video in "real time" the PC encodes the video lightly and at a low compression ratio. The result is a file that is a lot bigger then it needs to be. In order to get the file small enough for distribution the video will have to be re-encoded at a latter time when it does not have to be encoded in real time to get the max compression. The initial recording format I already have figured out. The re-encoding format for distribution is where I am at now. TSCC to get usable quality runs about 20 Mb per minute of video so for a 90 minute game the file would be 1.8 Gb. I am real close, right now I can get the final file size down to about 8 Mb/min with hardly any visual quality degradation.

I wasn't joking. Indeed gmail is a good solution, cause we can use all our bandwidth to download the file.
The main problem is that gmail doesn't allow files bigger than 10 mb.

Right, can you explain how you see this gmail thing working in practise then?

dont know if its going to be a big help but polish o2 allows 20mb files, with 1GB of whole account capacity

sure thing, and it's easy to use even if you dont know polish www.o2.pl you just fill empty spaces on the left with username and password

there is a way called p2m (peer 2 mail) which uses a free mail account to split the file in .zip files and upload or download them from the mail server to your pc. Now gmail doesn´t allow to use p2m with its accounts, but we can use walla, spymac or any other allowed. www.peer2mail.com/

Ok I have got this thing nailed down. we should have perfect quality and a file under 1 gig. Unfortunately against my better judgement the final format will have to be DivX. There is bound to be some problems with playability with some of U having the right codec (this is why I did not want to have to use DivX) but we will cross that bridge when we come to it. I still have yet to run a full scale test ie. record a 5 round game to check stability issues with the video capture program and WWP. Any volunteers?
