yes and no, IMHO. Firewire definitely _was_ the best way to get video,
off cheap or expensive video cameras, and therefore it will continue to
be used and provided for a long time. BUT (!) I think the paradigm is
shifting to camera's with more intelligence - consider the "purist" such
as myself, who likes to get exactly what the camera recorded.
Firewire leaves the video stream open to a bit of interpretation - such
as what format to store the file in; exactly what frame to start /
finish on; how to encode the audio, etc. This is all well and good, but
every time you capture the same minute of video, you may end up with a
slightly different output.
Directly downloading the video as a file however lets you get the exact
checksummable file that the camera decided to record. You could do it
10 times and get the same result. The camera can make a direct relation
from each pixel captured by it's CCD('s) to each pixel on each frame in
the video. How it then compresses this video is up the the quality of
the camera, but at least I can be sure that I get the exact, in sync,
video and audio, at the correct aspect ration and resolution.
That's what I think anyway :) It is of course my opinion to prefer USB
filesystem over firewire, and others may differ. I do predict though,
that with the ease and speed of USB filesystem transfers vs firewire,
that any hard drive video camera from the cheapest to the expensive
amateur models will soon have (if not already) this option.

i meant its main function is taking photos. an added feature is it takes movies, i wouldn't consider it a serious camera. show us what you are getting in dmesg when you plug in the camera. and i think it is very stupid that someone would make it so you could only transfer photos with usb. if it shows up as a hard drive you should have to do more or less exactly what garry said. if you can get a usb thumbdrive to mount on your computer, you should be able to mount your camera in the same way.

Re: [gentoo-user] OT :video cameras and gentoo
I don't believe that's the case for video cameras, which usually use firewire for video transfer. I have a customer who bought a DV camcorder with a USB socket & it transpired that this socket was only capable of transferring photos from the camera (which had both a video and a static "photo" mode). Video had to be transferred by firewire. Although videos appear in the mass storage device of my mum's digicam in "proper" video recorders firewire is MUCH more common. If I wanted to record video I would expect to be buying a firewire-capable video camera; although I might well take Iain Buchanan's advice of 13th August 2007 00:00:23 BST to supplant my previous expectations, I wouldn't expect USB is a "serious" camcorder.

After playing around with video camera's for a few years, I have come to the conclusion that the best way to go is the hard-drive based models, such as the JVC everio series (their 3CCD model looks nice). I've done lots of firewire video capture over the years, including a few amateur wedding videos, and the biggest pain is capturing and storing the footage. With a HD model camera, you just plug it in like an external hard drive (JVC works this way, I assume others would be the same) and download the video files. No need to worry about how to encode, because it's all done for you, and at the exact aspect ratio and quality that the camera recorded in. Very fast! A mini-DV camera takes 1 hour to download (capture) 1 hour of footage. A mini DVD camera only stores about 1/2 per DVD. A HD camera can store 10+ hours, and take only 10 minutes to download it! > Hopefully I can find a video > > camera that transfers directly to a gentoo > > sytem via usb 2.0?

i have a sony digital camera that takes movies, and it just shows up as a usb drive. i would assume that the video recorders would work the same way. maybe you can take a laptop to a store that sells them and check to see if it works that way or find someone that has one and borrow it. if you dont want sony recorders im sure you can find another brand with the same interface.

I think with Linux you will be limited to FireWire port only; correct me anybody if I'm wrong. -- #Joseph On Fri, 2007-08-10 at 17:39 +, James wrote: > Hello to all, > > I'm in need of a portable video camera(or rig), such as the > sony SR82, but one that is gentoo friendly > for video transfer.

[gentoo-user] OT :video cameras and gentoo
Hello to all, I'm in need of a portable video camera(or rig), such as the sony SR82, but one that is gentoo friendly for video transfer. Hopefully I can find a video camera that transfers directly to a gentoo sytem via usb 2.0? After my experience with a Sony Viao Laptop, I'm not really keen on anything else from sony (now that I think about it). Another nice feature would be the ability to use the laptop screen for viewing (while recording) instead of looking at that 2.7 in popout screen. A remote control (wireless or via the usb cable) from a gentoo linux system would be keen. Am I dreaming or has somebody seen a linux friendly video camera. My target is to record video at football and basketball practice where my kids play. Or maybe somebody has interfaces a PTZ (pan tilt zoom) to a linux system and record in ntsc(pal) then later on convert to h.264 or such? I considering mounting the PTZ camera on a pole, so I can sit in the shade or a camper and record video, gentoo studio style... (beginning to sound like a project). Maybe use a logitech joystick to map all of the camera functions and use a laptop for recording (under the shade) ideas? James -- [EMAIL PROTECTED] mailing list
