I think I’ve come to a compromise with the scene. I was messing around the instancer, but it was too poly heavy, so I upped the AA on the hair and increased the segments. Looks a little better, not exactly what I wanted, but not bad either.

excellent, thank you!

Excellent! I didn’t even think of that. Thank you both so much for all your time.

This is my first time doing slowmo for 3D, so I wanted to make it as smooth as possible. What I did was render the frames that I needed as slowmo in Cinema at 210fps and everything else was 30. So I was guessing this would remove the possibility of warping.

In AE I interpreted the footage to 210, and put the input fps for Twixtor at 30, since that’s what I’ve seen work in the past. I suppose it’s just going to take some exploring to get this to work, as I’ve only used twixtor one other time.

Thanks again Walter and Dave

Thanks again Walter.

I finally figured out how to create a matte using an object buffer. I then applied the obj as FG Matte 1 as a precomped luma matte. It’s working great to cut the train out of the scene, but now my problem is, how do I reveal the background? I tried adding the twixtored background but thats warped.

Here’s a picture:

Also, I read up on the manual. It helped me get the idea, but didn’t seem to be complete after luma matting the object.

Ok, so I’ve rendered out the obj buffers easily. Added them to my scene and applied the first one as FG1. I inverted the second ontop of a pre-comp, but couldn’t figure out how to add anything but a mask to the the BG layer, so I created a mask around the train and added that.

I also read to keep the FG on alpha, but as an alpha it made the scene look like trapcode shine was applied to it.

When I mess with the sensitivity it changes the warping around but doesnt really remove it.

Thanks so much. I’ll give this a go and report back soon.

[Ryan Ainge]

Thanks for the response Walter. I’ve never used an Obj Buffer in Cinema so I wanted to walk through a couple details before I set my computer to render again, just ot make sure.

To do:

Add compositing tag to train
Assign it object buffer one.
Add obj buffer 1 to my multi pass

Questions:

Do I need to an external compositing tag to it as well?
Since I already have the rendered slowmo frames I want, is there a way to ONLY render the object buffer by itself?
Or if thats not possible, can I just lower my render settings to the absolute lowest since the object buffer isn’t effected by AO/GI etc?

Once in AE take the obj buffer pass and add it to FG 1, the invert it (assuming like a mask?) then from there I’m guessing that will clean it up a bit.

Just wanting to make sure I do this the right way since that slow mo scene took 2 days to render 🙂

Thank you again

Great, thank you very much Adam

[Ryan Ainge]

Ah! That is simple. Thanks much
