Just left SMOKE for MAC DEMO, have more questions.

Hey I just left a SMOKE for MAC demo, and I have a few more questions. I appreciated the guy doing the DEMO, but I stumped him every step of the way. I think he was pretty green, and mentioned numerous times, again, and again, that there is a steep learning curve to SMOKE.

1. YUV.
How are you guys dealing with YUV codecs? The demo guy said their will be a gamma shift, because the codec will be YUV and the rendering of any effect/dissolve will be RGB. He said you just apply a LUT. And I was like you apply the LUT to the dissolve? or the whole clip?

He didn't have an answer. How are you guys dealing with mixing RGB/YUV codecs?

2. LUT management.
He didn't know how to import a LUT, but can you import LUT's pertimeline, per clip, per entire project?

3. Digital Painting.
He didn't know how to paint, but can SMOKE for Mac animate paint stokes? So say I do a beginning part of a stoke here, then finish down the timeline, will that stoke animate?

Hi John,

As far as am aware there are no gamma shifts when mixing RGB with YUV. If you import a codec that is working at YUV, it will exist in Smoke RGB environment and it should look exactly the same. There should be no need to apply LUTs to the clips either. This is not an issue.

For LUTs you can use them in all Autodesk system products in two ways. You can apply it just to the display so that you keep your material in LOG space but display it on Linear screens. The second way is that you can apply a LUT to a clip and physically convert it from LOG space to LIN space for compositing.

Smoke also has a paint tool that can paint strokes over time. It is located in the paint module. You simply load your clip into the paint module and use a tool called auto-paint. You can choose how long it takes to paint the stroke and you can even track the stroke to your images.

I run a Flame and Smoke video blog on the Autodesk area - http://area.autodesk.com/blogs/discreetuk and I am covering all aspects of the software and funnily enough I will be posting a video blog on auto-paint, so check it out this Friday/Saturday.

I am slightly concerned that you had a demonstration of smoke and the "demo guy" did not know his tools properly. He should have been able to deal with your questions as they are not out of the ordinary. Please would you let me know this was (you can message me privately on the autodesk area on my blog)

Kind regards

The truth is, the Smoke does have a relatively steep learning curve, especially compared to FCP. But, the Smoke has a very deep toolset, and is a far better system for finishing then FCP. I highly recommend getting training from Autodesk on the Smoke, it is money well spent.

Paint is a very powerful tool. It does have AutoPaint, which will allow you to animate a paint stroke on a scene, and like Grant mentioned, even using tracking on that paint stroke. This is a great feature when doing something like object removal, or touch up.

How about media that is YUV that is soft imported with dissolves in it?


I take it smoke is doing a YUV>RGB conversion before proc on any YUV codecs when soft imported also?

Is this why media on a 500MBs+ array (DAS) with a codec with a datarate of 40MBs still doesn't play RT ?

Everything is processed in RGB. When you render that dissolve, you will end up with RGB dpx frames on your storage.
