Mine crashes too, but problems are in software.
If there would be defect memory _all_ software would crash _all_ the time, when they would try to use that defected portion.
How does pro still photographers cope with cf-memory, if that is somehow less “Zero Defect Tolerance”?

[Jan Crittenden Livingston] “Zero Defect Tolerance”

All digital memory is usually Zero Defect Tolerance.
Otherwise programs in computers would crash.
For absolute certainty you would need ECC memory (used in servers).

AFAIK you don’t _have_ to have pixel shift to avoid striping.
You can take a sample from center of a pixel and represent it as it would be from the whole area of pixel.
Then you of course need very precise timing in quantization to sample the centers of a pixels, not the sides.
But that’s why video cameras usually have constant sampling rate.
Am I wrong?

[Emery] “Also, whats stopping people from connecting a hard drive to a PC adapter?”

Maybe one restrainer might be that fast enough hdd is 3.5″ sized and it needs AC.

Firestore for HD might be raiding couple of 2.5″ or 1.8″ hdd’s to be albe to work with batteries.

I have no real experience with p2’s (like most of us here),
but I have understood that they are just fast memory without any further intelligence.

Jan once said that they tried microdrive pc-card as a replacement of p2, but I believe
that they were trying to record dvcpro50 to it and microdrive just wasn’t fast enough.
Maybe they didn’t inspect the situation more closely.

But _if_ you would like to record only 720p24 and _if_ the card does not record dupe frames,
then next generation cf-cards (16GB) should easily handle the bitrate (40Mbps = 5MBps).

If you don’t see any problem with varicam’s 46mins recording time, then 2 * 8GB p2’s 40mins
shouldn’t be a big problem. Then if you could use 2 * 16GB cf-cards the time would be 80mins!

Going to jungle depending on laptops and hard drives (which need AC) might be a bit alarming.
Even normal rugged ENG cameras can have problems with all that moisture.
(16mm film would of course be the safest.)

And with LaCie’s Bigger Disks, everybody should remember that their capasity and speed is
achieved by bundling four hdd’s in RAID-0, which means if one hdd fails, you loose everything.
So backup with bigger disks is mandatory!
Btw, lacie has a new “Biggest Disk” enclosure that can be mounted as RAID-5, so it would be
a lot safer.

I’m not a dsp programmer, but in addition to gamma correction, they make all kind of low pass filtering, color correction, white balance, edge enhancing, skin tones, knee, toe, elbow & other body parts and lot of more.
If the end product is 8bit and changes to picture is made in a intelligent way (not too recursively),
I don’t see any reason for more than 12bit in dsp.

And for the resolution, I hope it isn’t more than 1280×720, that’s enough resolution and more would be always away from sensivity.

[Toke]

If you are going to shoot 720p24 with varicam, then you’ll have 40 mins with same format to two 8GB p2’s.
Then buy two LaCie Bigger disks with your laptop. Other one is for back up.
You’ll have to offload p2’s 2 times during shooting to get 120 mins.
You’ll get 48GB from hvx a day, making 1.5Tb total for 30 days, which just fits to Bigger Disk.

Other option is to buy 6 p2’s. Or more if you are shooting with higher framerates.

P2 CF-card adapter might be also interesting. By the time camera will ship there will be 16 GB cf’s for about $400…

My vote goes also to detachable!

Well, if average European commercial channel has now 50% of American programs, switching to American frame rates would not make any additional costs.

I don’t believe switching between different framereates would be a big problem, if it’s demanded from receivers to handle them.
Already here in Finland AR changes when going to commercial brake, programs have different audio languages, different dvb subtitling, teletext subtitling, mhp services etc.
Programs are played out from servers where they are stored in file format. Pure digital stream is then statistically multiplexed and transmitted within dvb signal.
Now where would the problem with changing frame rates be?

Video equipment has been independent from AC electricity Hz for quite some decades.
Or did you mean that tubes would flicker?
