Emulating Avid performance

Seems some Avid systems use 'striped' arrays that you need special code to read.
That got me thinking. If each video track was a contiguous file on a seperate drive with it's own pipe to the CPU things should run a lot smoother. After all it's the seek time of the drive that's the killer rather than the data throughput.

Common guys, I want this feature in V6!
Then we can all say we use a 'Pro' system cause nothin else can read our files! Oh and yeah that'd mean you need a drive for every track, that I like, a tower of 50 drives all blinking away, now that's got to impress the clients.

Buddy, I have an AVID Media COmposer gathering dust since our editor decided he wanted a career change. I know how to use the system but being primarily an old fashioned shooter (tripod, always think of previous shot and next shot) most of my work can be very easily straight cut (no fancy real time effects) so those super cool striped SCSIs just sit there. Vegas does everything I need except easy rolling titles/lower thirds and I have Adobe Premiere for that. AVID is a good product but I don't use it. I think we are getting another AVID editor in a couple of months so he can go nuts with the system.

I still want an EDL Suitable for the Labs to make a neg cut.. Then IMHO Be Professional ..

Here's a funny thing about AMC, when ever anyone rings up asking for a DV deck with component O/Ps I say something like 'you getter better quality ingesting via firewire' and they say 'Yeah but my system can't' and I say 'Ah, you've got an Avid Media Composer' and I gather Avid want the national debt of a small country to put 1394 into that system.

But all joking aside, I was originally thinking of doing it using Vegas and having one track on each drive, nothing as complex as SCSI, just SATA drives, not even in RAID.

Mark, I'm curious. How many times do you anticipate using the EDL feature?

Jay Why ?

But seriously, maybe this could be helped out with some heavy duty caching. After all, it's pretty easy for software to predict what's next on the timeline.

This also gets into the sort of hardware dependency that Vegas avoids religiously. To design it, you'd want a base Vegas system that just works, and then optional drivers for Vegas-like a massive read ahead driver to work with big striped arrays.

Not only does it have to read ahead, it has to process ahead as well. Definitely time for a dual cpu system then.

Maybe you could sell the whole module for $1200.00, not including the fiberchannel controller and 10+ disk array.

Like I said, I'm just curious.

I dont know On a day by day or weekly/Monthly/ Yearly basis Hope that dosnt sound Sarcastic But Its a little like asking me how Many Posts I intend to make I have no idea perhaps I may become succesfull perhaps I may more likely never get past this level I anticipate NO I Know I will use this Facility if it were available at least as many times as I need to...

I dont really understand the Nature of this question

Confused ?

Mark, there's nothing to be confused about. You said you wanted the EDL capability added to Vegas. I was simply curious to know how many times you thought you might be using it if it were available.

You answered my question. Thanks!

Sometimes the "How often would you use it" question is a little misleading.

Suppose you had worked for 5 years on a 2 hour documentary. You had about $200K into it and you planned on using EDL output at the end (for whatever reason).

The answer here is "I'd use it once". And maybe that's enough. It's a big "Once".

It's like my favorite producer comment. "It's a really short shot. We don't really need to light it". My unsaid retort is "we are we shooting it, if it's not important?" The point being, if it's important enough to shoot, then it's important enough to do it right.

Similarly, if a step is important to your process, it doesn't matter that you'll do it only once. (This is not to say that there isn't a better way to do it)

you seem to be OK With my answer of Uncertanty... Just that you know I would use this facility is sufficent..

The reason I mentioned an EDL suitable for a neg cut in this thread.. Bob has mentioned in a previous thread that it is possible someone here could maybe do it..and also its something I would definately use

Rob, your point is well taken and fully understood.

Thanks!

Rob

My answer was

"if it were available at least as many times as I need to"

was not really an answer.... This was where my confusion lay... How could I predict an outcome That circumstances ect could alter to such an extent as to make the question and answer pretty much Unanswerable..

I missed the fact that what Jay was really asking is would I use this Facility if it were available..

This was where my confusion lay..
