Poor image quality when uploading an image with Rise
Hello,
I created and saved-for-web a .png image in Photoshop. When I uploaded it with Rise (as a centered image in my blocks-lesson), it converted it with poor quality. Is it possible to avoid tho...
Hi everyone!
Do you have an image that looks blurry in Rise 360? We've designed a workaround to keep your images looking crystal clear.
If you'd like an image to keep its specific file format and not undergo compression, you can opt-out of image optimization on a case-by-case basis. Add _NOPROCESS_ to the name of your image file. It'll upload and display exactly as you saved it. Keep in mind that the 5GB file size limit still applies, and you could see an increase in your output file size.
My own experience on this issue is that Rise uses a very agressive compression of bitmaps when stored on the cloud during authoring, not on final export. I guess that this is intended to limit the storage cost. But amazon and google have image archive solutions that preserve quality and are offered for free.
In previous Rise releases, full color PNG images where always palette-reduced and dithered without warning. Now they are always converted to JPG and the poor quality produces a lot of artifacts on flat areas.
Anyway, the current situation is not acceptable for a quality (and costly) authoring solution and should be addressed. Maybe on general settings you could configure the media quality for storage? At least, you could preserve PNG quality and apply compression only to JPGs. That way, authors could choose what kind of image to use for different scenarios.
