Re: [Avid-L2] GPU upgrade from GTX-680 to ????? Mid 2012 MacPro 12 core

Thanks for the confirmation.  Am I correct that by manually setting Resolve to only use the GTX-680 for GUI and not processing that Resolve is then capable of using the Titan X cards at full strength with their 12GB vram?

Yes that is correct. Resolve is limited to the slowest card, utilizing only the least amount of VRAM available.

Sorry John, I don't know the answers to your other questions.  The 780 6Gig card just seemed like the perfect card for me and my 2010 MacPro 5,1.  It has worked out for me well, and I believe it is a good fit.

I felt that since the MacPro only supports PCIe 2.0 spec and all these cards are spec'd for a PCIe 3.0 motherboard, that their extra power and features would be lost on a computer who's buss can't really support their faster output.  I recall reading an article that someone did tests with a bunch of the Nvidia cards in a MacPro and saw a diminishing return at a certain point on the power of the card, vs. what it could do in PCIe 2.0 on a Mac Pro.

Also, important to me, the 780 card was far cheaper than the newer breading edge cards.

Here is a stepping off point to the rabbit hole that got me started a few years ago, from everymac:

Another great website for turning the detail knob to 11 is Barefeats:

https://barefeats.com/

They have done tons of articles comparing computing power and performance, and they have some great tests of interest to video professionals.

The above two websites are enough to delete your entire weekend down the proverbial rabbit hole.  Apologies to your wife.

[Avid-L2] Frozen video in timeline

After editing all day on a Macbook Pro (Mojave), I come in the next morning and Timeline video will not play in the record monitor. Audio plays fine. Only way to fix issue is to restart my computer. Any ideas what could be causing this? MC 2019.11

Re: [Avid-L2] GPU upgrade from GTX-680 to ????? Mid 2012 MacPro 12 core

I have been using an NVIDIA GeForce GTX 780 (not the TI version) with 6 gigs onboard ram.  It has worked great for me, though I have not tested it with Resolve, or newer MacOS versions.  I am still running El Capitan on the machine that uses it, but getting ready to jump to HS.

Per an article from Apple website it is Metal compatible:

https://discussions.apple.com/thread/8613487#:~:text=The%20installed%20graphics%20card%20is,%2C%20it%20supports%20%22Metal%22.

This card may be an option for you, and flashed versions are available through Macvidcards.com (whom I hear is kinda flakey this days on his GPU business).  I got mine on e-bay a couple years ago.  Its a very solid card with one caveat.  It is power hungry and requires dual cables.  More than what you can draw from the two mini PCIe power connectors on the motherboard.  I used one of those, and piggybacked from my SATA optical bay for the second.

The card works fine most of the time, but if you hit it hard (like with a 3d render test) it will eventually shut down if you don't have it properly powered.  The Pixelas mod is also workable to power it.

Increased CUDA cores will affect performance more. More GPU RAM will allow more nodes and FX before you get the dreaded OUT of GPU Memory issue.

[Avid-L2] New Blue Titler 7 Ultimate Updated Credit Roll Issue/Solution?

It took me 4 hours to add one line to a new blue Titler Pro Ultimate 7 credit roll yesterday.  I could open the New Blue and make the change and it showed in the New Blue interface but when I would save it the timeline  would just say scrub to update.  Also changing the global position parameters was laggy and just plain weird.  I could not scroll effectively to adjust Y position as it would just start the spinning beach ball after a slight move.  I tried the mouse instead of the pen on my wacom tablet but no improvement.  Typing in numbers I couldn't seem to go from negative to positive.  It seems the parameter numbers don't seem to update until you actually scroll the timeline.  Today after a response from New Blue it seems that the brunt of my problem was that New Blue takes forever to cache when you make a change.  By forever it can take 4 minutes for it to cache after just retyping a name in the credit roll.

Unlike Avid title tool the credit roll is just a big text document that gets globally moved along the Y axis to make the roll.  I know After Effect workflows do a similar thing so that part seemed simple but just retyping text can take 10 seconds or more to see the text update.  I'm on a beefy mid 2012 macpro with GTX-680 2GB vram and 12 core 3.46 GHz and 64 GB ram.  There is also an expansion chassis with to TitanX GPUs with 12 GB vram.  Still New Blue is kludgy at best but I find it works better promoting Title Tools than Avid's Titler+.

So today I just waited the 4 or 5 minutes for the green progress circle around the play button in the New Blue Interface to complete and things are playing nicer.  Also if I click to type in parameter if I wait like 10 to 15 seconds the typed in numbers will appear.  It's all frustrating but this is the first time I had a credit roll.

Hope it helps someone else be patient enough to get it to work.  I'm thinking if I upgrade my GTX-680 to a better GPU it might really help New Blue as I think it likes a lot of vram.  I'm at the cusp of not wanting to abandon my TitanX gpus by losing cuda support and all that stuff that I hear goes away in Mojave.  I'm still Sierra and High Sierra on two different boot PCiE SSDs.

Here's what I heard from New Blue support,

"

Please be aware that making any change to the credit roll will cause the entire thing to be re-cached, which can take a significant amount of time. After making any changes, I would suggest leaving the Titler Pro interface open while it caches the credit roll and not closing it until after that finishes. As shown in the attached screenshot, once the title is fully cached there will be a green circle around the play button. You can watch this circle draw around the play button to monitor the caching progress. I wouldn't be surprised for this process to take 5 - 10 minutes or longer to complete. Once it's finished, you should be able to close the Titler Pro interface and view / playback the credit roll on your Media Composer timeline without any issues. 

More than likely when you were seeing the "scrub to update" message the credits were still being cached; the process tends to run faster when Titler Pro is open and in the foreground rather than using the background rendering option with the interface closed."
