-
-The only known case where thumbnails might be missing on desktop is when
-uploading **videos** during a Google Takeout or watched folder sync on **Intel
-macOS** machines. This is because the bundled ffmpeg that we use does not work
-on Intel machines.
-
-For images, we are able to fallback to other mechanisms for generating the
-thumbnails, but for videos because of their potentially huge size, the app
-doesn't try the fallback to avoid running out of memory.
-
-In such cases, you will need to use the following workaround:
-
-1.  Obtain a copy of `ffmpeg` binary that works on your Intel macOS. For
-    example, you can install it via `brew`. If you already have `ffmpeg`
-    installed you can copying it from `/usr/local/bin` (or whereever it was
-    installed).
-
-2.  Copy or symlink it to
-    `/Applications/ente.app/Contents/Resources/app.asar.unpacked/node_modules/ffmpeg-static/ffmpeg`.
-
-Alternatively, you can drag and drop the videos. Even without the above
-workaround, thumbnail generation during video uploads via the normal folder
-selection or drag and drop will work fine, since in those case we have access to
-the video's data directly without reading it from a zip and can thus use the
-fallback.

-## Regenerating thumbnails
-
 There is currently no functionality to regenerate thumbnails in the above cases.
 You will need to upload the affected files again.
