KI Pro stops record with 10% left
I purchased a KI Pro to replace a IO/HD and lap top system for digitizing the international version of the show I am currently editing. We are in 720 and the international needs to be in 1080. The system worked great except that with about 10 minutes left in the show, the KI pro stopped recording. It said 10% left on the display and would not record any further. Luckily, we were still in the test mode of the new system and we were dual recording using the IO/HD. Is this a safety setup so as not to record to the last bit.
We can’t trust the system until the 500gb drives come out. It will work during pre-pro to digitize clips for features we are editing. It worked great for that. Set up a producer or AD with the Ki-pro and a tape deck. They could log field tapes and digitize at the same time, just don’t tell the DGA.

Just curious, but was this from a long record or where you starting/stopping?

I was starting & stopping so as not to have one large clip to cut up.

[Kenyon Blower] ” The system worked great except that with about 10 minutes left in the show, the KI pro stopped recording. It said 10% left on the display and would not record any further.”
That is correct, the unit is not designed to work until full, it will auto shut down when there is less than 10% of the active volume left, this is designed as a safety measure and is common in every disk based recorder I have worked with. (have you ever noted this limitation with scratch disks is within FCP also)
My question is why? if you are starting and stopping the recording process, why not swap out of drive while you are doing that, I have a good deal of practice and I can easily swap a drive over a commercial break.
What kind of show are you recording and how? I have now done a couple of large multicam shoots (6-10 cameras) on 3 hr concerts and not run out of room on my setups working with ProRes(non-hq) and all were done at 1080 60i.

[gary adcock] “it will auto shut down when there is less than 10% of the active volume left”
That seems to make sense. Is the actual, usable drive space listed anywhere for the AJA 250GB drive? This would come in handy for future reference when I only have 1 250GB cartridge and I’m using AJA’s data rate calc to figure out how much record time I have. I wouldn’t want to overshoot.

Gary pretty much answered my question which is why I asked. As of right now, the Express34 cards aren’t operational, so there’s no roll over function. I would simply buy another $250 dollar 250GB drive.

Copy that, but either way I’d like to know what the actual recording capacity of the drive is with the 10% buffer. I guess I could just figure it at 200GB to be safe.

Or just knock 10% off the posted available space.
How much footage did you have when it wouldn’t go over 10%. That should be your ballpark.

Yea, that was my question. Where is that posted? I don’t own a KiPro so I can’t pop in a drive and check it. I’ve never recorded long enough to encounter the 10% limit, but for future reference I’d like to know the correct amount of usable space so I can calculate my record time properly. That would be one devastating “gotcha” in a live event situation.

[Michael Craven] “Where is that posted?”
Right on the front if the KiPro when it’s on.
It’ll say something like D1, 77%.
Here’s a pic from the Transport Controls web interface.

No, I understand that part. I’m talking about an actual number, like 234GB (for instance), of actual recording space on a 250GB drive. Until I know the actual number I’m just going to use 200GB in my calculations. That should keep me more than safe.
Thanks,
Mike
