Don’t panic, there is a 50/50 chance that your files are somewhere hidden in the output folder.

1. Refresh the output folder (There is a purple refresh button at the bottom of the file browser)

   

2. Check the following nodes in the workflow, Save Image/Video Combine, there is a chance your output folder and file names are set to a specific value.

   1. Please NOTE, there are only four folders that will be persisted across machine sessions,

      1. /home/user/ComfyUI/custom_nodes
      2. /home/user/ComfyUI/models
      3. /home/user/ComfyUI/input
      4. /home/user/ComfyUI/output

   2. So please do make sure your output path is actually in /home/user/ComfyUI/output folder

      1. We have seen numerous times that customer put a path, such as /home/user/ComfyUI/videos, /home/user/ComfUI/shots, /home/user/ComfyUI/results, etc., that are not going to be persisted across sessions and you won’t be able to find them in the file browser.

      

3. Remove VHS video combine node and re-run the workflow, leave the Save Image node there so you could come back and get all the image frames at least.

   1. We are seeing VHS video combine node crash silently a lot when dealing with scale of hundreds frames (300ish and above, depends on the resolution).

   2. Why can’t I have both Save Image node and Video combine node at the same level so it will save the image (as a failsafe) first then try to combine the video?

      1. Because you don’t know which one is going to be executed first from the first appearance, thus there is a very high possibility that VHS is going to run first (and crashed), then Save Image (will not run due to ComfyUI crashed already).
      2. If you want to know which one is going to be executed first, go to ComfyUI-Manager, turn on the Badge: #ID Nickename, and you will see a small number on top of each node in your workflow, the execution order will be ascending based on that number (if the nodes are in the same level).
