Having your videos sorted in order from oldest to most recent makes sense for archiving and viewing continuity. Therefore it is recommended to check any tape labelling and add numerical order if you wish, if not already done. Do not worry if this is not possible as you can rename MP4 files yourself when you receive. If labelling is on outer cases and not on tapes, do your best to try match correctly in case tapes are not in the correct cases. If tapes are not labelled, do not worry. Check handwriting is legible, feel free to add post-it notes with clear labels or a list of tape names can be sent digitally by email which can be copied and pasted when creating and naming your files. You can number with 2 digits such as from 01,02, 03 if you wish in order. Also avoid punctuation, use only spaces, dashes and underscores in names. If you have access to a computer, you can always rename the files yourself to suit.
