Red “effect failed to render” problem

[Jean-louis Coté]

Hi John,

If you have 2 video cards take one out. That’s what I did and the problem disappeared. But I think you have only one card. Here’s something you could always try, although it should not have an effect… try unplugging one monitor, maybe your card has trouble driving 2 large monitors. I have a ATI Radeon HD 2600 XT with a Dell 24 inch and a Dell 19 inch and have no problem.

You should call Apple and complain because this problem is unreal and I have found no solution with 2 cards.

That’s a good idea, Jean-Louis. I’ll see what happens with just one monitor. I also just found this on the FX Factory forum:

“Open your Sequence Settings window
Switch to the Video Processing tab
Select the “Render in 8-bit YUV” option”

I’m not sure if I had this selected in Settings, but if not, I’ll will try this tomorrow as well.

Update: The above suggestion worked. No problem rendering now. While this doesn’t fix the issue if you need high-precision rendering, it does let you move forward.

Having same problem – but have just one video card driving two monitors. Changing the render setting to 8 bit YUV did not work for me, but unplugging the second monitor did.

Strangely the fxplug rendered fine on my old G4 (Dual 1.25 with Radeon 256 card) … but will not render on my brand new Mac Pro.

Even more bizarrely – having unplugged the second monitor to get the various fxplugs working, I tried plugging the second monitor back in, and it all still works! So maybe those with second monitor cards may find that having removed the second card to ‘fix’ the problem, it’s safe to plug the second card back in…

Seems this is going to be a tricky bug to fix.

I to am having this problem.

I haven’t got a second monitor and have the aforemention render in 8 bit YUV ticked.

The only thing that I do have is the FxFactory plugin’s, so they must be at the root of the problem?

I’m on a MBP 2.4 4gig Ram FCS2 (all latest versions)

Mmmm.

Had the same problem. Solved by disconnecting the second monitor and rebooting Final Cut.
