Will a "professional" GFX really solve all rendering errors?

Rendering errors.

As you might know, dear reader, a lot of people are fighting with rendering problems.

For me it's always been persistent and prolonged a majority of projects by at least 50 % just to get the project out of the computer(s) we have at the studio.

After recently updates, instead of giving "Error Compiling Video" it now actually gives an error code, and I can see that on all our machines it's nearly always the GPU that causes the problem one way or the other.

We have a variety of different GeForce GTX cards, but we have not any Titan cards that I assume is labeled as "professional". So now my question is: Will it change my rendering experience if I dig deep in the pockets and buy one of these extra expensive cards? Is that what it takes? or...

We have been editing RED with 4 to 8K material, starting 5 years ago an editing and rendering have never been easy. It's just now at this point where I am also getting older, and I wish I didn't have to sit night after night trying all kinds of weird methods so I by the grace of the rendering God, can have my film ready for deadline.

All rendering errors? Doubtful. It depends why you're getting the error though, are you running out of VRAM? Do you have enough VRAM to render each frame? There is some math that can tell you how much you need depending on your frame size, let me find it.

Ok, I'm back and I couldn't find it, but perhaps a friendly face from Adobe could. Kevin-Monahan, do you have that info handy?

You might try a GTX 1070 with 8GB of VRAM. They run for under $400 at Newegg.

With frame sizes that large, lots of VRAM might be called for.

Yea ... and lots of cores, threads, system RAM ... PCI lanes ... SSD drives ...

Modern editing Life. Hardware still makes a huge difference.

If you want to get a real assessment of the performance of your system(s) run my Premiere Pro hardware BenchMark (PPBM) maybe you have other weaknesses. Submit the results for free feedback.

Thanks for all the answers guys!

The system right now is right beefy, and I suspect the only weak link to be the GPU - especially now when AME gives the error code related to GPU every time.

We do mostly edit in 4K sequences, and output to HD. Honestly I gave up trying to output to 4K because it's a 100 % fail these days. At least with 2-pass and maximum render quality turned on.

And, the GTX 970 only have 4gigs of ram, so perhaps that is the short coming?

Bill Gehrke thank you so much! i will do that next time I am near my workstation! super excited to see that result.

Maximum Render Quality is only required if you do not have GPU acceleration!

I recommend not using either.

MRQ will shove GPU accelerated processes to the CPU and slow things down dramatically. Likewise all you really get from 2 pass is a longer cofee break.

I noticed that I've seen some small glitches and banding disappear when using two pass. Can't that be true, or is just me playing tricks on my self?

we often scale and move around our 6K footage, and I have this idea that maximum will make that scaling quality better.

I will do a side by side comparison, but can you explain why the options are event here in the first place if it really don't make a difference? It's confusing to navigate in software where there are options that are actually obsolete. No?

Oh the struggle.

CUDA will offer the best scaling quality. MRQ will force the process back onto the CPU. You don't want that.

Thank you Jim.

Amazing news to be honest, because it is so darn slow with MRQ.

So for now and in the future I can just leave it off? Great news.

Do you still insist that two pass is obsolete?
I will do a side by side comparison when i'm back from my travels.

Max Render Quality can at times be of help with scaling/moving/resizing issues. But with many of the recent GPU's, it's not seeming to be needed as much. And sometimes it can add time and/or glitches of its own.

Max Bit Depth can be very useful with 10/12-bit media and heavy color correction/Fx work. But again ... not always makes a difference, and can add time and the occasional artifact.

2-pass is one that as Jim says, seems to be mostly unnecessary ... mainly adds time for most projects.

But like anything else in a professional workflow, test it yourself of course. If you need one of them, well ... you do need it. If not, save time & hassle.

It's like the "Import sequences natively" option in the AME preferences ... for a whole bunch of issues, it needs to be turned off.

I've not found it useful in a while, but...your proposed test is not out of order.
