High Quality YUV Rendering Problem

[Steve Drew]

Thank god someone else is having this problem!

I’ve been too busy to post it recently and have just been rendering everything at 8bit as everything WORKS at 8bit. 10bit also gives awful results on multiply transfer modes in the timeline.

I get the green garbage around my photoshop alpha edges, as you said, but only when I’ve got a drop shadow on it. I’ve found a cumbersome way around it:
Firstly, check that the clips giving you the grief are photoshop “sequences”, not the individual layer from the photoshop sequence.
Then remove any FCP drop shadow effect.
Open up the photoshop sequence by double clicking it
Apply the drop shadow to the layer INSIDE the sequence
Than return to your master sequence – all should be good.

It would be dandy if this was sorted.

Thanks for that, it only shows on Photoshop captions when I applied, in this case a ‘cube spin’ effect, it shows as the image compresses. I had a lower third name caption over an after effects animated background with drop shadow and it gave the garbage with no effect applied.

I don’t know if this is a Blackmagic or FCP problem, I guess the boys at BMD are busy with IBC. I’ll wait and see if they can shed some more light on the subject.

Hi Roddy,

I’m having trouble reproducing this problem. Perhaps you can send us an email at support[at]blackmagic-design.com or if you have any test files, drop us a download link so that we have a common working reference.

Hi guys,

We’ve replicated this problem and further testing points the problem to a possible bug in FCP. We have logged the bug appropriately with Apple and are waiting for their response.
