Best quality export for News streaming at DVinfo.net

Sergio Perez · August 1st, 2005, 09:14 PM

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.

That's the problem. They aren't used to receive. I'm not going to send to them directly, since their internet communication network is non existent. SO i'm planning to have someone from my production team over here receive the file and burn it ready for delivery. So, any suggestions?

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
