Does 60P use more hardrive space and work computer harder?
 

Hi GUys,

It's a question that has been on my mind. If you record in camera at 60fps as opposed to 25fps does this make the file larger when capturing to hardrive and does this make the computer work harder. It just make sense that 60 frames will be harder on the computer than 25 frames a second. Look forward to hearing your thoughts. Thanks

Size will be the same. HDV format has not changed. Yes, marginally more cpu power would be required to play a 60p file vs. 30p. If you involved yourself in a heavily composited timeline then the effect could be as much as 2x the work for the cpu. 2x the frames = 2x the work. As well if you transcode to an intermediate codec your disc space will increase, as it will be converting the efficient mpeg2 codec into individual semi-lossless frames for efficient editing, but then that would probably require far less cpu power for editing over native editing making it null in that regard.

Thanks, as I thought, it would be even harder on the system. I cant shoot 60p on my hd111 so thats cool, just makes sense that its more work for the old computer.
Ok, thanks dude

Now I'm not sure if you're talking about 60 frames per second or a shutter speed of one sixtieth of a second (progressive scan or otherwise).

Some of the new camcorders will indeed shoot in the slowmotion mode, and the HC3 will record at 150 fps for short bursts. I imagine this would indeed be tough on the camera's recording system (hense the short bursts), but when feeding the signal to the computer there's no difference in the bit rate.

Hi tom, yeah I was referring to the 60 frames per second recorded to tape and then working with it in post. My hd gy 111 does not offer hd 60fps unless recording from the components out but I dont believe there is a compact unit that can store that data directly off the components out, I hope someone comes up with a unit though, it would sell very well I am sure.

Your HD111 has a 480p60 mode. Don't be shy to try it out. Looks very close to 720p, and is great for intercutting butter smooth slo-mo's. Gotta try it!

I will do, thanks for that, I have heard mixed feelings about shooting 576, here in PAL land, 480 in the U.S. Do you uprez or just stay SD. Do you mix your 720p with 576p or 480p in your case, is that possible or does everything have to be the same. Silly question but I just want to see what people do. Used to be straight forward, Standard def, 25fps, 4:3 or 16:9. Its great though, all these new possibilities.
