svideo or firewire? |
|
|
Hi there.
(I'm new to this stuff)
I have a video camera capable of outputting to svideo or firewire and I want
to do video editing on my pc.
My pc has an svideo port, but not firewire. Should I buy a firewire card or
will I be able to download my digital video tapes to the pc using svideo?
Thanks in anticipation :)

Thanks everybody - firewire it is!
I remember the days when PC's had it as standard. Mustn't have taken of eh? |

Firewire is 100% same quality as original tape. If you have a fast enough pc
you can create full digital video, HUGE hard drive req'd though. 15pounds
for
a firewire card.
Although I use firewire, USB2 is faster. Get one of those instead.

Are you advocating using a usb2 connection to transfer video, over a
firewire one? If so, you're mental. |

I'm afraid I'd disagree. It is *supposed* to be faster, but USB2 is a
"step-down" communication protocol, and will rarely run at anywhere
near it's max speed (and much slower than firewire).
Get one of those instead.
Not something I'd recommend.
While all video editors support capture through firewire, not all will
capture through USB2. And relatively few digital camcorders support
USB2, while all support firewire.
I'd be interested, BTW, in learning just which digital camcorders DO
support USB2. Ditto with video editors.

Firewire is a communication protocol. It has nothing whatsoever to do
with quality. It is the method used by your video editor to store the
captured video (AVI DV) that maintains the quality.

Imagine the loss of quality:convert the analogue signal of the CCD (s) to
digital, then to analogue (for the svideo) then to digital (inside your pc)
then to analogue (for you to view in the screen)...etc etc.

The issue is another. A signal over S-Video must be captured/digitalized.
DV over FireWire is copied bit by bit. This may (and most probably will)
cause a worse quality of videos captured over S-Video compared to the
same video transferred over FireWire.

A few modern camcorders support USB 2.0 for digital video transfer to a
PC. My Panasonic PV-GS400 is one of those. From my experiments with it,
I'd say there is no difference in the results of off-loading a DV tape
with USB 2.0 or Firewire.

Oh dear, here we go again.
The above is garbage.
S-Video is analog
DV is compressed.digital 4:2:0
Any analog to compressed digital means a quality loss.
Quality copy table
IEEE-1394, STIR 10
SD I 9.8
Analog Component (YE, R-Y, B-Y) 9
Y/C ("S-video") 8
Analog Composite 5
Point camera at screen and pray 1
Also, a conversion between different compressed digital formats gives a quality
loss.

Do try to get it right :-)

No quality loss there...

Untrue...
of videos captured over S-Video
Perhaps you could inform us just which video editors allow the capture
over S-video?
compared to the
| Quote: | same video transferred over FireWire.

You are confused.... Here, I'll try to help you understand:
S-video ---> DV = no quality loss
S-video ---> AVI DV = no quality loss
DV ---> S-video = quality loss
AVI DV ---> S-video = quallity loss
DV ---> MPEG = quality loss
MPEG ---> DV = no quality loss
device(1) ---> Firewire ---> device(2) = no quality loss
Take it step-by-step :-)
Device ---> Firewire ---> device(2) = no quality loss.
Take it step-by-step and I'm sure it will become clear.

So you have a 100% efficient capture solution then? No external noise
introduced? Perfectly shielded cables etc? I think not.

nonsense. DV is a lossy compression codec. No analogue > digital
conversion can have no quality loss, no matter the codec. Better kit
will do a better job, but it is IMPOSSIBLE to get a lossless analogue
capture.
| Quote: | DV ---> S-video = quality loss
|
Agreed.
| Quote: | AVI DV ---> S-video = quallity loss
|
Agreed. Although that's what you just said above. Repeating yourself?
| Quote: | DV ---> MPEG = quality loss
|
Indeed
| Quote: | MPEG ---> DV = no quality loss
|
Nonsense again. For the same reasons, DV is a lossy codec. What is
"mpeg" anyway? That's a pretty vague term these days.
| Quote: | device(1) ---> Firewire ---> device(2) = no quality loss
|
Keep spouting that bullshit, tony. |

Because it's cheaper, not because it's faster.
I have a USB2 external hard drive and it works OK for capturing video to my
laptop but it's barely able to keep up when I scrub the timeline or do
anything involving multiple clips from different files.

Not at full quality DV resolution they don't. My Sony camcorder supported
"webcam mode" through USB, at lower resolutions, and it supported the use of
USB to act as an external media drive to copy JPEG's and compressed clips
off the memory stick. But that has nothing on a full-resolution DV capture. |
