Trapcode Shine only 8bit YUV?!?
I am trying to use Shine(tastefully!)in a DVCPro HD 720 24p timeline. It looks great when I setup the effect but only renders correctly in 8 bit yuv. I does not render correctly in RGB or High Precision YUV. Trapcode suggests that I use High Precision YUV to render their plug-ins correctly.
Anyone have a clue what to do?

I use Shine quite often, but never in FCP. It renders quite well in After Effects RGB, and comes into FCP just fine. Never had a compoaint.
Have a wonderful day.

The DVCPro HD timeline is only 8bit anyway, just leave it set to 8 bit render.
I’ve never used High Precision YUV render in any of our projects.

the time I used it once I had image quality issues, Shane confirmed at least
at the time that FCP is buggy with this setting. -
Whenever you start with 8b footage and end up in 10b, or you force High Precision rendering, or you end up with an 8b picture quantified in 10b.
If you mix in your time-line 8 and 10b footage, you will end up with a movie half partially rendered in 8b and partially rendered in 10b.

where did you hear that?
Forgive me but that doesn’t seem possible the way the fcp rendering engine works.

Hi Chris,
Nothing to forgive. I will be very happy if you correct me when I’m wrong.
I understand that when you put 8 and 10b footage in a 10b sequence, if you apply any filter to the clips the filter will be applied in 8 or 10b depending of the bit depth of each clip. After the resulting picture will be combined in 10b.
If in a layer you put 10b footage with a glow. In the top layer you put an animated logo with a blur.
FC will apply the Glow in 10b to the lower layer. The log will get his blur in 8b, and the two layers will be combined in 10b.
There are two other practical reasons that lead me to think like that:
– Probably this was a bug, but no long ago whenever all the footage was 8b and the sequence was 10b on exporting you end up with a movie tagged as 8b (in the QT info window) unless forced High Precision. This is not anymore like that.
– I’ve appreciated some banding problems in 8b pictures put together with 10b footage. The banding disappeared when I forced High Precision rendering.
Anyway I wish I could have more information about the insides of FC, not only about this matter but about many other questions.
We are talking since a couple of years about problems when with 10b codecs and 32b rendering. The truth is that I haven’t had no one so far.

There does not seem to be a way to post examples…Anyway, the 8 bit render is nice and shows the typical “Shine” whites blown out with basically the orange fire that surrounds the alpha channel of a graphic. On the High Precision YUV, the part that is supposed to be blown out is a transparent yellow color- it should be white like the 8 bit version. If I crank up the boost light=the same yellow interior, although on the screen and monitor pre-view the image is blown out and white. Does any of this make sense?
The sequence is DVCPro 720 p24.

the hi precision setting is buggy. heck even the 10-bit rendering
has some flaws in it according to Graeme N. Thankfully fcp renders
8-bit VERY well. -
Right,Nattress said few times that the 32b rendering was broken in FC.but I haven’t heard a complain in almost two years.
Now many people are working with ProRes and, at least here in the COW, I don’t see post reporting any problem.
