What says Cotty?
24 and 25 fps is a 'progressive' frame rate. That is, there are litterally 24 or 45 frames per second. They're indistinguishable - unless you try and convert one to the other. Picture? No problem. Sound? Problem! But hey. Surprisingly few things are shot 25p for UK broadcast. It can give a very jittery look to unsmooth camerawork or rapid movement in the frame. The standard framerate for UK broadcast (PAL) is 50i ( that is 50 frames interlaced - 25 frames per second, 2 interlaced fields per frame) and in the US (NTSC) 60i. These rates give a much smoother look, but also some would say a very sterile video look. Shooting at 30 fps will smooth it out that little bit more. The most important thing in any video acquisition format is bitrate. Most people think they can go buy a Canon 5D and shoot a lovely doc and try and hawk it to a network. Ain't gonna happen. All networks from the BBC down ;-) will only accept certain bitrates set out in their technical requirements. For most broadcasters across the globe you're looking at 50 Mbps on acquisition. 35 for news. Top end drama and docs 100 Mbps for some. High stakes indeed. That said, who needs old fashioned broadcasters? I'm producing 6 short videos for the British Chiropractor's Association on best practice re posture and the target is Youtube. Horses for courses. Got a camera? Go shoot something, cut it together, broadcast it on the web. Your viewers will find you! It takes some time to get the hits though. I produced this video about a top London cakemaker 18 months ago and it's only just reaching 45,000 hits: <http://www.youtube.com/watch?v=JqOaGyXkV1k> I fall asleep watching it but if you're into wedding cakes they tell me it's best of the best. People ask me what the most important aspect of video is (eg cameras, bitrates, editing etc) and I always say the same thing: learn how to tell a story! If the viewer so much as turns to his Mrs to ask for a cup of tea after starting to watch your video, you just lost him. I noted the discussion about manual vs autofocus and both camps are right. If I'm shooting on the big (main or A ) camera I must have manual focus - absolutely mandatory. But for other things like a small camera on a pole for a topshot, or on the dash in a car looking back at the driver and so on, autofocus on a locked-off B camera is fine and dandy. One of the reasons i got my little Fuji X10 - I can shove it anywhere on a magic arm and record video (and pretty good audio!) with the AF keeping things sharp. Well, that's what i told the Mrs. And then I can play HCB with it at weekends :) I don't understand the K-01 at all, but that's just me. .02 -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ---------- http://www.cottysnaps.com _____________________________ -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
