convert GIFs with Transparent background to DXV

Post by dsquareddan »

Hi I'm trying to incorporate a few animated gifs into my visual set. The gifs I've found have transparent background. When I save them to my computer (OS X 10.11), they still show up as transparent in the preview window. However when I go to convert to DXV with Alpha, it renders the background as white. I've tried with Adobe Media Encoder & VVBatchExporter. Trying to get a download of Quicktime Pro 7 to see if that will let me.

has anyone had any luck with this?

I just tried this with Adobe After Effects. It was interpreting the alpha as solid white when I imported it. I fixed by chroma keying the background out then exporting.

Doesn't AE have an option where you can set the color for premultiplication? Should be under the file right-click > Interpretation menu.

Maybe I am doing it wrong. But the alpha section is greyed out after importing a .gif with alpha.

Ya but the problem is then that if there is white in color in the gif it gets keyed out as well

Open your transparent GIF in Photoshop.
Save it as a PSD document.
Import it in After Effects as composition.
Drag all layers to your comp in AE
Select them all
Size them to be 15f long
Right Click, go to Keyframe assistant, select Sequence Layers and click OK
Adjust the beginning and end of your work area to match the sequence (so if you have 8 layers, total duration would be 04:00 and the out would be at 03:29 at 30FPS)
Render as DXV3 with Alpha and you should have a transparent animation that matches your GIF
