What is Instant Upload / File Matching?
All files sent are stored in the system for many months. If you go to send the same file again, from anywhere in the world, the file will match to the one already available and will not need to be uploaded again, only matched. This matching is done using sophisticated hashing checks to ensure files are identical.
When you download watermarked files from StudioCDN, the system records the hash information. If you send this watermarked file to someone else it will match back to the original file first uploaded. This ensures that all watermarks are first generation (for best sound quality) and improves the performance of the system.
