We have uploaded few asset for example below in to AEM Assets with background color white. But after uploading the assets AEM converted into black background.
After uploading in to AEM Assets it looks like:
Can you help us to understand why it is happening? and also which preview server AEM is using to generate the preview of asset?
Can you please help us reproduce this? Which AEM version are you on?
Is this happening for all Assets or few?
Reference Read:- Apply image presets or dynamic renditions
// Custom Renditions
Access the DAM update asset model from the workflow console (classic UI view steps listed below)
We are using AEM Asset 6.4 version and it was happening only for few asset. It might be because the dynamic media was not enabled.
