I don't see in the docs which image or video formats are accepted by Sencha. I discovered by myself that tif images are refused while png's are accepted, and I can't load a mp4 video that I made with ScreenFlow.
What formats goes with Sencha ?
Thank you for the suggestion, we will look into adding this to documentation.
The image formats that are supported by Animator are the same ones that are commonly supported by webkit browsers. These are: .jpg, .gif, .png, .bmp and .svg. TIFF format is not supported by any major browsers.
About the movie, it will not play inside Animator project when imported, but when you export the scene, you should be able to see / play it. MP4 is supported, and should play correctly. If it still doesn't load after export, please let us know.
