FS7: XAVC-I 4K in premiere?

Not necessarily.

Ben said he was using G-Raid drives, they should be plenty fast enough for 4K. But yes, I agree drives are usually the weakest link.

On my MacBook Pro I find PP to be a fairly 'clunky' experience. FCPX flies along, shame I hate the hate the interface...

I was editing music vids and commercials on Lightworks in London in the early 90s Ben. I've edited on film, tape, Avid and just about every NLE, that early version of Lightworks stills stands out to me as the best cutting tool in history.

We thought we were frightfully advanced - cutting multi-cam concerts on TK'd slow band Umatic, reading the VITC off the master, conforming into Lightworks on super expensive 2 gigabyte drives, cutting it frame accurately and then doing a neg cut at the end of it all.

Yes, a lot nicer than XAVC in Prem Pro. It is something I'd like to solve - and, no, I can't stand FCPX either...

Ben.

I don't use a lot of video effects, but I do want to run some kind of technical grade on log clips, so clients don't whinge.

I can imagine you are dealing with LOG material coming from different sources often. As a professional editor, would't you want to invest in a dedicated hardware LUT box or at least a monitor which supports it?

No, I only cut my own material now - all shot Cine EI/Log3 on an FS7.

A LUT box won't sort the exposure, which varies significantly on actuality shoots (Cine EI has saved my arse many times....) I use an Eizo CG247 montor - but last time I asked them, they're not yet supporting LUTs.

I could do a one-light grade, as Doug talks about with his Resolve workflow, but my schedules and shooting habits don't really allow for that these days - the last time I did a one-light TK was 1999.

And, dammit, if FCPX can work smoothly with this stuff, why can't PP? :-)

The two-drive G-Raids? They'll only hit around 200-220MB/s, and if that is the case, I'd suspect that'll be the issue. The times I had issues with XAVC were when I had to run it off anything less than my four-drive raid or SSDs.

I'm not a FCPX user, but I had been under the impression that instead of working with native XAVC-I files it was rendering them to ProRes in the background, in which case it's apples and oranges...

In regards to a different point, on hearing that a company has the most up-to-date systems I've often found that their idea of high end was very different than mine. On a PC I'd expect that you'd want not just a recent i7 but at least 32GB of RAM and a GeForce 1060 or higher processor, preferably with at least 8GB of graphics RAM. While I might consider that to be entry level, a corporate buying exec might consider it overkill.

One other thing I've noticed about Premiere is that it's really important to keep your graphics card drivers completely up to date.

Also - Are they dealing with the RedRaw files natively? or converting them?

You might want to spend a little time on their system yourself to see what the truths are.
 
Interesting thought. I'll look into this. It was bought on the advice from G Tech that it would far outperform the needs of XAVC, so I've not really considered it as the culprit.

Have you run Black Magic Disk Speed Test? That will tell you how good the drives really are. My edit drives read at about 1150 MB/s and write at about 1000 MB/s.
 
Don't forget to put latency in equation, it's not just pure bandwidth.

Get enterprise class SSDs, such as Intel DC S3700 800GB, enterprise class RAID controller card, such as LSI MegaRAID 9271.
With 4 drives in RAID 0 configuration, you'll get min. ~2GBps read / 1,6 GBps write on an old 2010 Mac Pro wit PCI-e 2.0 bus in AJA system test with real 2k (2048x1556) 10-bit uncompressed frames .
Add 4 drives more to double the numbers. Add another card with drives to octaple the numbers.

That would be enough on-line storage for projects in progress, use low-power 7.2k HDDs on integrated SATA controllers for near-line storage.
And back-up everything on tape regularly - LTO 6 (7).

What's interesting with Intel's S series Data Center SSDs is that there are no slow-downs, wear and tear, TRIM pauses, deterioration with time or fear of loosing data.
They were made as plug and play replacements for 15k enterprise drives, where none of above nonsense can be tolerated.
When I was researching the way to be employed and configured in the system, an Intel engineer revealed me what were their goals when designing the drive and the advantages over the rest of concurrent consumer and 'PRO'(sumer) SSDs. TRIM hiccups and no slow-down when drive is almost full are the most important ones that come first on my mind.

If you are not using it in server case, don't forget to put small fan on RAID controller heat-sink. A pair of 40mm Noctuas serves me well.

And that's it. Set and forget.

On more important thing, newer software versions use more of hardware features and use them more efficiently (usually at the expense of stability).
Don't expect large benefits when upgrading CPU and GPU or buying new system while using the old software that doesn't know how to take advantage of it.
 
Hi. I started a similar thread for XAVC-S. Then I found a pretty decent solution for my playback and scrubbing troubles, on the adobe forums. It turns out, the issue was a bad driver for an additional SATA controller on the MB that I wasn't even using; I disabled that controller on the BIOS and it feels like a new PC. Check this.
