3. Repair Damaged Files

A lesser-known feature of Format Factory is its ability to repair damaged video and audio files. Users often keep a portable version of 4.3.0 on hand specifically for this purpose—if a file won't play, running it through Format Factory can often re-index the data and make it viewable again.

Step 4: Batch Processing (The Real Power)

FF 4.3.0’s batch mode is where it shines. Add 20 different files of different formats (MP4, AVI, MKV). Select one output format for all (e.g., MP4). The software will individually process each file without user intervention. This works exceptionally well in v4.3.0; later versions sometimes crash with large batches.
