everything has lag Jason...that is jsut how it is

Jason Rodriguez · October 6th, 2004, 03:19 PM

Yes, I realize that everything (electronic) will have lag, but the chief issue is HOW MUCH lag.

I don't mean to be making this an issue, but it can quickly become one if there's too much lag to follow fast action. In other words, if you're 5-6 frames behind, that can become quite a hinderance in recording fast moving footage.

HUGE progress today!!

things have been reworked and the CineLInk is looking REALLY good..gone from 100% CPU on preview to about 40-60% cpu..frames are SMOOTH now and the image slicing is GONE..not much time now..I will update later...I am excited!! Steve, don't choke on that muffin! :)

Hey Obin,

Great news!

BTW, if you can, how many fps are you getting to your hard-drives? I know you said as many as you want, but realistically how many, at least with the SI-1300? Also are you still recording RAW files, or is there another format that you're exporting to?

Also how fast is your CPU?

Obin Olson · October 7th, 2004, 12:06 AM

I have a glitch in this beta I just got but I should get around 30-50fps 720p on a fast SATA disk drive...maybe more with that special 10,000rpm drive someone was talking about on this board...plus it will save images on 2 disks at a time. This will speed it up alot..I will let you know

still RAW files and converting them into tiffs 8 bit at the moment..very soon 16bit and quicktime Sheer or any Quicktime codec you want ;)

CPU is a 3ghz tower machine at the moment...will be a Mobile Intel 2.6 or 2.8ghz on the micro board

26.37 - 43.95 MB/s sustained on that SATA drive Obin? Which
drive is that?

Obin Olson · October 7th, 2004, 07:06 AM

I get 26-30MB sec on a standard SATA disk drive 50-60MB/sec on 2 drives

I will test the 3300RGB today with 1/4 quad preview and see how that is...and we are working on the "bug" that is not allowing save-to-disk

Rob what is the datarate of the 3300rgb 1080x1920 12bit raw at 24fps? and what is it at 8bit 24fps?

don't we have a table on this board with all the real-world datarates of the SI cameras?

Jason what was the link for that tiny motherboard..it's about time for me to order one ;) for testing!

I know it was not this board:

Rob Lohman · October 7th, 2004, 09:59 AM

Obin,

Again, your programmer should easily be able to supply you with
such a table. But here are your answers:

1920 x 1080 @ 24 fps : 12 bits in 16 bits = 94.92 MB/s
1920 x 1080 @ 24 fps : 12 bits packed = 71.19 MB/s
1920 x 1080 @ 24 fps : 8 bits = 47.46 MB/s

Obin Olson · October 7th, 2004, 10:15 AM

so RAW 12bit would be 71MB/sec?

Rob Lohman · October 7th, 2004, 10:29 AM

If you pack it (ie, not put it in 16 bits), yes.

Jason Rodriguez · October 7th, 2004, 12:23 PM

the board was the SBC83810 from Axiomtek

http://www.axiomtek.com/product_deta...2+x+8%5C%22%29

hope that helps (and hopefully I can start building one soon too :)

Obin Olson · October 7th, 2004, 12:38 PM

thx Jason that is it

Jason Rodriguez · October 7th, 2004, 01:30 PM

Hey Obin,

The fastest you're going to get is 2.0Ghz, because you're using Penitum M, not the Pentium 4 M (the Pentium M is much faster BTW, even at 2.0Ghz, and yes, I know, it's confusing).

Obin Olson · October 7th, 2004, 01:33 PM

do you think the 2ghz M will have enough power for 1080p 1/4 quad preview and raw data save?

Juan M. M. Fiebelkorn · October 7th, 2004, 05:36 PM

To anybody interested, take note that usually you have a minimum lag of around 20 milliseconds at the video board level.
At least expect to have that delay if everythings works perfect......
