Title safe was from days when the tube (CRT) of the television was masked by a bezel that surrounded it. There was a lot of slop in how much was masked, how much the manufacturer overscanned the tube/border combination, etc. No good way to know, so title safe was very conservative. I’d say with LCD monitors, this is much less the case, but not everyone has LCD monitors yet. For the web, you get no border or masking, so you can use the full frame without regard to title/action safe. (i.e., you are right)

I’d say it depends on what working space the 255 level is in. RGB video in most computer video environments is perfectly legal at 255,255,255: it’s 100 IRE. Likewise, 0,0,0 is 0 IRE (or 7.5 if you use setup in the output hardware). The 16-235 range is for SMPTE digital. _Some_ hardware/software environments do use this (AVID for one, I think). But most (desktop) computer environments can use “direct math:” i.e., 0.75 x 255 gives you 75% bars: 75% red = (RGB) 191,0,0 for example. Consequently, a system using the 0-255 range is not able to output superblack or superwhite, though illegal saturation is certainly obtainable.
Look at it on a scope to confirm…

I think Jeff P. notice what I did not: Photoshop sequences. Have you tried setting preview mode to something more video-oriented, like Yuv-AVI?

Video capture boards are very fussy to configure, and do not work with all motherboards. My Xena2Ke works OK with my Core i7 system (SuperMicro motherboard), but will confess I only use it for output. It might have trouble with capture– I don’t know.
The best place to start is look at the AJA pages and find an “approved” motherboard that has a layout most like yours, and try the arrangement they illustrate.
Also– What kind of tapes are you capturing?-Jeff

I am not a hardware/RAID expert, but it sounds like you are using a software (Win7) RAID 0 ? If so, I would wonder if that is the issue– the system is juggling Premiere and software RAID at the same time. Perhaps something to investigate…

What kind of problems are you having?

No: pulldown is for putting 24P footage into 30i playback. Or, for ‘extracting’ 24P footage (that was originally 24P) out of 30i footage. You’re in a situation of squeezing 30 frames into 24. So, yes, get Twixtor…
There’s some good info about pulldown HERE.

You have more experience that I do! But, for what it’s worth, I built my current workstation about 7 months ago. The only issues with my Intel SSDs (one system, one “scratch” drive) were: having to make sure the system BIOS was set to AHCI mode on installing* (for Win 7 to recognized SSDs as such). Added the Intel management sofware, which I have set to “trim” once a week. My disc I/O in “Windows Experience Index” is 7.5. The mobo I’m using is a SuperMicro X8DAH (single i7-hex) as part of a 5046 “barebones workstation.” [nice unit, BTW].
*in my case, I found out _after_ installing, and had to do some voodoo to switch from non-AHCI to AHCI to get the drives seen as SSD by Windows. At this point, I forgot what the ‘voodoo’ was, but I don’t remember it being too painful.

If you can spend a little more for your system drive, I’d suggest a SSD (Solid State Disc). It will make program loading quicker; I’ve been very happy with mine on a recent build (Intel SSD; Win7pro; SuperMicro MB).

It may also depend on the processing in your LCD monitor. I use a JVC-Pro LCD monitor (via an AJA board), which absolutely does show interlaced signals properly in HD or SD (or improperly, if I screw up!). I believe some consumer LCD monitors process everything to progressive– which is OK for consumers, but not for producers. Wish I could be more specific for you.
