FS7: Premiere multicam question

This may be the wrong place to post but it doesn't look like many people frequent the editing forums here so:

How powerful a computer do I need to cut 4 4k cameras multicamera in current premiere ?

I have an imac 4 cores, i7 single processor , 3.5 ghz , 32 Gs ram , Nvidia gtx 780M graphics card w 4G VRAM - (cud )

probably cut a mix of FS7 and A7sii cams,.
Will that work ?
 
Give it a try. I suspect it's on the cusp, but not unreasonable. Or better yet, just convert to proxies, do your cut and then link back to the full rez files to finish.

I can do it - BUT - the sources cannot be own the same hard drive. Perhaps an SSD could do it, but my usual drives can't. With a couple on the fastest drive and one each on separate drives it works fine - with just the occasional stutter on my pretty fast editor.
 
+1 on having Premiere Pro generate proxies on import.
Will save you a lot of aggravation.
Premiere automatically goes back to work with the original (full res) files when you render/output your cut.
(Only issue would be if you are in a time crunch and need to go directly into the edit without having enough time to generate proxies. In this case definitely use multiple SSDs for your source material)
 
Thanks a lot. I haven't cut much in a couple of years and was previously on FCP7 so this will be a maiden journey of me on Premiere and with 4K . Proxy certainly sounds like a good idea.
One of my main questions was whether it makes a difference for multicam to spread my sources out one a few drives or just it put it all on one RAID or SSD? I'm guessing Paul ( above ) is right to spread it out.

About 6 years ago I had surprisingly good luck running 5 or HD cameras in a multicam on FCP7 with a laptop, and that time I spread my sources out among 3 ESATA drives.

So if I go with Proxy files do I still want to use a RAID or SSD's or will I be OK with USB3 or ordinary ESata drives?
 
Just noticed I can get Sansung 860 EVO 1 TB drives for only $167 on Amazon . Maybe a pair of those would be all I need. I won't have more than an hour of footage .
 
Get a pair of the Samsung drives in a dual-drive enclosure and RAID with DiskUtility. That would be very fast.
 
+1 on chat about drives - they're the significant data bottleneck. I forked out for a G-Studio Thunderbolt 2 24Tb tower plus iMac 5K last year and they're OK - but still not what I expect as an editor.

Multiple streams? I'd definitely do proxies.

Thanks a lot for all your help again everyone. I still don't even have a lock on this but as i'm new to Premiere and editing 4K and in a multicam there's a lot to think out first. Seems to be falling into place though and looking forward to it.

I would definitely do proxies, but wondering if I still need SSD's . I'm figuring yes to getting a pair of 1T SSD's (USB 3) but not raiding them. Wondering also if I shoot Log would the additional weight of using LUTS slow down the multicam. If so I'm thinking I could burn in the LUT for the proxies and go back to the original log for final?

Yes - totally. It's my biggest bugbear with PP - LUTs slow it down to near uselessness.

Add a basic grade to the proxies and you shouldn't need SSDs, if you use a lightweight proxy like ProRes LT. Decent high speed spinning disks should do the trick.

By the way, my first "proper" music concert edit in 1994 - for a UK band called Take That - involved initially cutting telecined proxies on LoBand Umatic, generating an EDL from that with the VITC and conforming the next stage of proxies with 2 second handles in Lightworks on super-expensive 2 Gigabyte drives. Final conform was done as a neg cut and then mastered on Digi Beta.

Nothing's really changed in 24 years... stuff gets faster, then the files just get bigger. And then you get LUTs...
