Best quality export for News streaming
I'm going to do a news coverage of an event in the USA, and I need to stream this news immediatelly for download here in China. Any suggestions to what compression I should use in order to achieve a respectable image for broadcast blowup? The business here is fast and reasonably looking.
What I have in mind is that file size shouldn't exceed 100 mb for a 1 minute clip. I was thinking on exporting the clip trough compressor in m2v. Someone would download the file and burn it on dvd. Then use the s-video connection of a dvd player to dub it to mini dv. What do you think? Probably not "Live"coverage, but a lag of about 1 or 2 hours seems acceptable for delivery. PLease help! |
Best to ask those you are delivering to what they are used to receiving.

DV would nearly do it, but it would be a little over 200MB for a 60 second clip.
What about photoJPEG? If they have Quicktime Pro on their side, they can drop that in and convert it to DV (without going to analog). PhotoJPEG I believe should give fast encodes and decent quality, although I haven't messed around with it much. |
you need one of the new efficient codecs that'll play back on a dvd player... i think that there are chinese-made dvd players for windows media and divx, for instance, and there is also a nero h.264 dvd player that's either finished or in the works, and it's also made overseas.

A DVD player may degrade quality slightly since you're going back out to analog and suffering a generation loss there. Why not just convert the downloaded file to DV and hit it off to DV tape?

thanks everyone. I'll mess around with the exports and see what I get..

try the new quicktime codex (quicktime7). I Find it amazing because the quality is reasonable good and it can be send easily over the internet. Dont know how it looks like as a blowup. BBC developed this codex together with apple and they use it for their multimedia purposes. It is better then jpeg that is for sure and a lot smaller in size.

Thanks, David. What's the name of the codec in Quicktime 7? Or what quicktime conversion are you refering to? |
It comes with quicktime pro. It encodes with the new H.264 video codec check the website http://www.apple.com/quicktime
