Converting SWF from JPEG to Lossless (LWFS)?

Hello,

I can't find a good answer to this on the net. I'm not developing this game in Flash specifically, but SWF is a flash format so I thought I would ask this question here. Feel free to move my topic, mods, if you think there's a better place to post this.

Currently, I'm trying to use LWF (http://forum.unity3d.com/threads/lw...ng-flash-animation-to-unity-and-html5.158771/) to play an SWF animation in the background of one of my game scenes in Unity. However, I run into a snag when trying to feed files to LWFS as per the guide posted by Gree, the developer of LWFS

When I post the SWF file to convert, it gives me an error saying that my SWF images are as JPEG, and they should be as Lossless. Does anyone know of a way to convert the SWF file from JPEG to lossless? Or a better way to load SWF images into a Unity scene? Thanks all.
