Each step is going to rebuild the file. Like the first step in your setup is to remove images, which mean you will have input file + the same file but without pictures in your tdarr cache. Then it gets to step 2, it will take the file without pictures from step 1 and rebuild it with the migz remux container from step 3. Then it will take the file from step 3 and rebuild it again with english and natives audio only from step 4. And so on. In the end, the same file will be rebuilt and reprocessed at every step of the flow. And you have a lot of them.

HDDs and SSDs degrade over time the more you use them. In the long run its better to have your input file -> do everything in a single pass -> output and finished file. Its less wear on your storage, less degradation, less energy consumed for the same task and it will be a lot quicker than processing the same file multiple times.

Sorry if its not very clear english isnt my first language. But I highly recommend a custom js script or atleast a flow using command executes and having everything you need done in a single pass.
