View Full Version : whats on the horizon for internet distribution of HD? Brent Marks January 21st, 2005, 10:37 PM whats on the horizon for internet distribution of HD? Will it be microsoft's new format.... wmvHD??? about 5to1 or HDV format What do you guys think..? thanks Nate Weaver January 22nd, 2005, 12:28 AM About the same as internet distribution for true SD resolution material. Nil. How do you think people are going distribute even 720p24 when it's not even practical to do 640x480 yet? Not until everybody gets fiber directly to their homes, and are pulling 50mbit down...a few years away, at the very least. Brent Marks January 22nd, 2005, 12:34 AM Bandwidth is extremely cheap now... I can get it for 10cents a gig... a 2 hour HDV movie would be about 4+ gig... so about 25cents cost to distribute... Do you think people are willing to wait overnight for a file like that?

I think AVC(h.264 like apple want's to call it) will be the next big delivery codec after mpeg2. I've done some subjective visual testing with Nero Digital and one can get dvd quality with almost 1Mbps. Apple has showed avc-hd with its qt7 with 8Mbps and I have undersood that is also target bitrate in avc-broadcasting (hd in Europe) and hd-dvd. So maybe adsl(2+/2++/3?) will be enough for households for a while. At least if they are not sharing their videos out... Steven White January 22nd, 2005, 08:59 AM When I complete the HD flick I'm working on I will upload several versions, and likely distribute them via bit torrent. For compatibility purposes I will probably compress with Soronson3 and WM9. At 1920x1080 (really 1920x818), 1440x613, 1280x545, 854x363 (or 720x363 if the PA ratios work out in-codec), and 480x204. There are plenty of ways to get true SD or HD material on the web through p2p networks, but hosting streaming video at that resolution puts a huge strain on people's servers. -Steve Brent Marks January 22nd, 2005, 09:50 AM Steve... would love to hear more about what you are doing! contact me via email: bcmedia -at- gmail dot . com Toke Lahti January 22nd, 2005, 05:09 PM <<<-- Originally posted by Toke Lahti: I think AVC(h.264 like apple want's to call it) will be the next big delivery codec after mpeg2.

It would be difficult to transmit a very long file that way, but it can be done. I hear a lot of talk about h.264, but I've yet to see any actual examples.

One comparison: http://www.doom9.org/codecs-104-1.htm Right now I know 3 major players in encoders: envivio, sorenson squeeze4 and nero recode2. From those I think envivio is the only one who offers free player. |
