Dynamic Media Dynamic Renditions are incorrect for assets with the same name

[zen_____]

After bulk uploading a large amount of assets to AEM Assets, I noticed that the Dynamic Renditions for some assets with the same name were getting "mixed up" - they have the wrong image content in the renditions.

For example:

I upload two assets: /content/dam/page1/HeroImage.png and /content/dam/page2/HeroImage.png.

Dynamic Media requires unique filenames, so these were created in DM as HeroImage.png and HeroImage-1.png respectively.

When I look at the Dynamic Renditions in AEM Assets for /content/dam/page1/HeroImage.png, it's showing the HeroImage-1.png renditions.

What is the correct workaround for this? It's not realistic to expect every asset in the DAM to have a unique name.

Hi @zen_____ 

Adobe Dynamic Media does not allow two files to have the same name. Each item’s Adobe Dynamic Media ID must be unique. Because of this rule, Upload to Application has an overwrite. The exact effect of this option depends on the specified Overwrite Images option you have chosen. These options specify how replacement images are uploaded: whether they replace the original images, or become duplicate images. Duplicate images are renamed with a -1. For example, test.jpg is renamed test-1.jpg. 

You would need to check the Dynamic Media General Settings configuration. These are the options available:-

1. Overwrite in current folder, same base name/extension

2. Overwrite in current folder, same base name regardless of extension

3. Overwrite in any folder, same base asset name/extension

4. Overwrite in any folder, same base asset name regardless of extension
