View Full Version : HD space -> Video Length

02-02-2004, 11:28 AM
I'm running VT[2] and have a little 110Gb Video RAID and I was curious if anyone out there knew a way to convert minutes to Gb's in Toaster, using just standard uncompressed video.

Any help would be greatly appreciated!!

I'm sure someone will post the exact numbers, but if I remember right uncompressed RTV is in the vicinity of 80GB / hour. For comparison, DV uses approximately 12GB / hour, and is a good choice for small or slower drives (or longer projects) if you don't need the pristine quality of RTV.

Don't forget that cache will use up some of your drive space, but as long as you're not doing an effects extravaganza it's usually not too much.

Hope this helps! -MG.

that link will dload a nice little codec storage calculator that does rtv also.

We basically use the conversion of 1 minute of RTV equals 1 gigabyte.

So 1 minute = 1 gig.

Simple math to figure on.

Pretty cool tool.
Just about every video codec there is I think.

Yup ! Already had it on the hard drive, but forgot it was there..... :rolleyes:

As mentioned, always use 'gig a minute' and you will be very close to actual.

Thanks to everyone who responded! MUCH appreciated :)

That's a great little utility - how on earth did you stumble on it? I tried to find some info on it from their home page w/o success.

It's just something they put together for their customers.

Thanks, Paul - I was looking to find a page listing details, and some info that would answer questions like 'would they permit a link from an outside webpage' with proper attribution.

(I don't want to stick a direct link on my site w/o permission, and yet I can't find it on their site to direct people to their page.)

ooops... well... ooops....

I've had the app for a while, can't remember where original link came from. I went to site also (Rorke data) to find info or link and couldn't either so a google search for the filename itself gave me this page:
That page gave me above link.

Cool app.

I'm sure there's no harm done, Jim - I just don't want to overstep. I'll send 'em an e-mail and see what they say. :)

This may be slightly off-topic (and I think it was covered somewhere else) however:
I made a 1 minute clip consisting of 75% NTSC bars from the 'Patterns' folder with 1 minute of 1k Tone (48k stereo).

This clip rendered as an RTV in VT[3] = 1,241,082 kb.
This clip rendered in AE 5.5 using the RTV format = 1,855,998 kb.
This clip rendered in AE 5.5 using Uncomp AVI = 2,468,960 kb.

If these clips are truly uncompressed, why the file size difference?

If I remember right the topic came up on the beta forums and I posted a direct link to it and several people got it then. However, the link at Rorke is not shown to you until you fill out a brief contact or 'more information' survey. So, they probably don't want a direct link made too public. But then again, they may appreciate the traffic to their site...

Those sizes mentioned look like the RTV from VT[3] is a "plain" RTV.

The RTV from AE is an RTV PLUS alpha channel.

And the uncompressed AVI from AE is in RGB space not YUV.

But these are just educated guesses. :)
