I need for a AMIGA 4000/40 a frammegrabber card.
I need for my software a very fast card (Z3 if possible)
I have a Macrosystem VLAB but this card is very slow.
explain:
librarie version =VLAB.library V8.2 (10 may 1994).
image size = 720 x 310.
when i give the function VLab_Scan() and i have the return of this function the
time elapsed is: 0,2 sec in gray & 0,6sec in color (YUV).
I need for work a card for grab a 310 x 310 color fullframe in 1/25 sec (in
pal).
My amiga Workstation have:
– AMIGA 4000/40 8Mo Fast
– Z3 Fastlane with 16Mo
– VLAB card.
– Amax IV
– EGS Spectrum in Z3.
All response are Welcomme.

Hello, for digitizing 25 pictures per second, you need a framegrabber with
realtime JPEG compression (for example the VLab Motion card). With this card
you can save a motion picture realtime to your harddisk. The problem is the
price of this cards (about 1800 DM), and that you need a very fast and big
harddisk to store more than a few seconds. Hope this helps you ,

Hello,
Yes i have been seeing this card in action but the problem is the file.
In Mpeg the movie is coded in one file the 3 or 4 first frames is normal
pictures, and the rest of the movie is delta image of this firsts frames…
For my development i need a very fast card to transfer in 1/25 sec a global
image at full video (broadcast). for using in my software.
I have never see the PAR, have you seeing this card ???

That's not how MPEG works. Every few frames are normal pictures. The frames
between are special frames.
