[Drizzt_G] “HD takes at least 5 times more storage than DV if not more.”
good point but not from someone that works in 444.
dv footage is about 3.75 mgs a second
1080p24 4:4:4 content is about 198.87 mgs a second.
1080p60 4:4:4: content is about 497.66 mgs a secondmy calculator says that is between 53x to 132.7x as much….

so far a 23.98 movie, played in a 29.97 comp in AE, and rendered out as a 29.97 movie has played back out in a 29.97 sequence in AE.”Why?
any board you are using to send the signal back out will do this on the fly when going out via SDI or component.?I do not understand why are you doing this in AE? the capture hardware will do this better than AE will and you must being using something to bring that signal in as 10bit Uncompressed.

January 8, 2006 at 6:47 pm in reply to: Video freezes every minute or so during capture.[Nick Balogh] “Im not sure what Journaling is…so i dont know if its turned on or not. I have no other applications running annd no other duplicate programs on the network.”
Journaling is an enhanced directory structure that allows Spotlight to operate efficiently, the process is time and data intensive
when we are talking about large volumes like your xraid.
Check in the disk utility to see if journalling is on which is most likely – since you did not know about it, you did not know to turn of off for volumes when using them for video capture.Gary Adcock

[Mariusz] “This is interesting statement since you can not record that much video on those cards.”
why ?
the P2 cards are in actually a 4 volume Secure Digital Raid 0 array. There are 4 SD memory cards striped together (controlled by an LSI chipset) Micro drives cannot yet maintain the correct spindle speed to achieve the capture rate needed for realtime acquisition.
The specs on this drive talk about read speeds and but not write speeds – with out the proper cache and raid control this is not possible.About LSI
this chip company makes a majority of controller chips for transmitting content over ethernet, fibre and SCSI in addition to a major supplier of RAID controller chips as is used in the Panasonic P2 cards
They also manufacture the Apple fibre cards and offer the windows driver for that low cost card on their web site.Gary Adcock

[David Davidson] “We’d be interested in shooting some tests to send to different labs. Especially tests which convert the material to a full HD 10bit 4:4:4 format, graded, put thru a film LUT, and how the material prints back with different negative stock. “

there are a couple of people already working on this – There is a soon to be announced 1/2 day session at NAB 06 where we we show this process from end to end. LaserPacific is suppling the us the proper support ( and their Christie 2K projector for viewing) while the x200 will only be part of the session, it will be one of the focal points of the process.Gary Adcock

I dont know what my options are at this point just short of reinstalling everything and re formating and re-striping the drives. Ideas?”
Please tell us you do NOT have journaling on.
your drives are fast enough to capture the footage you are writing.
you have nothing running in the background
— itunes, norton utilites/systemworks/ you are connected to the net running a duplicate or unlicensed copy of FCP —-anything that is not being used is not turned on.

January 8, 2006 at 5:54 pm in reply to: 24P advanced workflow in FCP and delivery at 60i[linkoping skrills] “im curious if there is a better way. or any kind of standard to making this work as well as possible. the 24pA is great and everything, but you cant be serious that plain 24p is way better for returning to 60i than 3223 advanced. “
in a interlaced 60i environment shane is correct, The advantage of the Advanced pulldown it it allows you to make a clean progressive frame. your are working in interlace, kinda defeats the purpose.
Secondly 24pA was never meant to be a “Viewing” codec. It was developed for progressive post when using a interlaced or segmented field capture. The “static frame” dupe frame look of 24pA has been know to be rejected by some networks transmission standards, they are accustomed to seeing the standard 3:2 pulldown.

[toke lahti] “Just tried to find from manual if there’s a setting in hvx200 for “V DETAIL FREQ” in 1080i mode?
If there isn’t, does this mean that 1080p24 always has reduced vertical resolution to remove line flicker from interlaced displays?”One has nothing to do with the other. Why? why should a progressive image have less detail than the interlaced content from the progressive capture. The camera has a 1080p imager. it starts as a progressive image.

[MR2005] “Can FCP 5 edit HD in a 4:4:4 uncompressed color space using a card such as the Kona 2/Blackmagic
for I/O? “yes, there are at least 10 post houses in LA using FCP and a Kona 2 for 444 editing.
