Is anyone aware of any tools that would help automate the process of creating a flipbook / SubUV texture from a video file? For example creating a fireball flipbook from stock video clip?
Here’s what I do:
- Open the footage in After Effects.
- Create a composition of the exact dimensions you want each SubUV frame to be and use the snippet of footage you want. Framerate doesn’t matter one bit.
- Math is your friend. If you want 28 (7x4) frames on a 1024x1024 texture, then you need a 146x256 composition.
- Render it out as a Targa Sequence. That gives you a folder with all frames of the footage you used.
- Now a little tedious bit. Delete the frames you don’t want. If you edited the footage to contain only the frames you want, you are golden.
- I use Contact Sheet II plug-in for Photoshop, which needs to be installed: (http://www.adobe.com/support/downloads/detail.jsp?ftpID=4688) or you can use the one from Adobe Bridge.
- Import all your frames using ContactSheet. Include no spaces or dividers.
- Final tweaks: move all layers 1 pixel up and 1 pixel left (I always found that necessary), give it all black background.
- Export as a single Targa subuv image.
Hope this helps,

Great, I will try this out. Thanks for the tip!
Thanks for the writeup and detailed explanation, Marcin!
Ok I tried this method out using AE and the Conact Sheet II Photoshop plug-in and it works great. (I also tried using Adobe Bridge output for the contact sheet but couldn’t quite get the right results). Regarding step #5, yes I found that lowering the frame rate in After Effects to the appropriate value can eliminate this step. (This can be found under the basic Composition Settings)
I am perfectly fine with this.
