Dropped Frames 720p 10bit on G-Speed

[Jeremy Garchow]

Are you sure your capture/render files are pointing to your GSpeed?

Have you mixed down your audio (select all {apple-a} in your timeline and then hit option-apple-r) ?

Using a disk speed test (free from AJA and I think Blackmagic has one too) what kind of speed are you getting on your drive?

Regarding FT, I understand your frustration but if Apple offered to buy you out to save the company otherwise you go out of business and can’t feed your kids, would you take their offer?

Hi,

Thanks for your help.

Yes, all media was captured to the GSpeed, and the render bins are on there too.

I had mixed down the audio. And went from 14 audio tracks to 10.

The tests on the Aja System Test for 1280×720 10-bit, 4 GB file size is:
write: 185.7 MB/s
read: 165.9Mb/s

I took my footage and dumped it onto a 1080i 23.98 10-bit and rendered it out and it worked fine. What up with that? LOL
Are the easy set-up’s in FCP a safe way to go, or do you always customize?

I’m beginning to think that it cant handle 59.94? only play’s back 23.98 and 29.97?

WOW, i didnt know FT was dooing that bad, well, at least his kids have nothing to worry about ever again, while the rest of us, well, I’ll just shut up and keep working before i cant pay rent, LOL

So you disk speed is up there, so it’s something in your project.

Does it conk out at the same place every time?
Is absolutely everything rendered? And when I say mixdown audio, I don’t mean mixdown in the avid sense, I mean mixdown the FCP sense. Mixdown in FCP is way different than the Avid term.
Is all of your media playing from the GSpeed?
Do you have any music/still frames/anything playing off of your boot drive?

[Vahe Douglas] “using kona Lh to 720p 10bit 59.94, going to 3TB G-Speed Fiber Channel. The capture went well, but now I can’t get past 13 seconds without a dropped frame on any playback (except playing back QT’s on desktop) and cannot capture at all. I have about 260 gigs left on the G-Speed and over 200 on my internal drive, 4 Video Tracks, 10 Audio Tracks.”

You say you have 4 layers of 720p59.94 @ 10bit??? Then each track of your 10bit video needs at least 147mgs a second to maintain that data rate. Thats over 588 megabytes a second the drive needs to maintain or over 2.5 times what the drives were built to sustain even in Raid 0

Also your drive is over 90% full and when any drive is that full- video data rates will diminish as well as system performance on your mac.
