--- --- Found 4 folders in the input directory with no PNG files, so they were skipped: 1. **Bag2PackScan_animation 2a** (0 PNG files) 2. **Bag2PackScan_animation 2b** (0 PNG files) 3. **Bag2PackScan_animation 4a** (0 PNG files) 4. **Bag2PackScan_animation 4b** (0 PNG files) The script only processes folders that contain PNG files, so these 4 empty folders weren't processed. That's why you see 28 output sequences instead of 32. All 28 sequences with PNG files were processed and have matching file counts in the output. The 4 missing sequences are empty folders with no PNGs to compress. If you want, I can update the script to create empty output folders for these sequences, or you can add PNG files to those folders if they should contain sequences. --- _**User (2025-12-11 18:21Z)**_ nah, we can ignore jpg, let's just report when we do that. --- _**Agent (model default, mode Agent)**_ --- Updating the script to process JPG files and report when we do: ---
