How Do I Convert Old Videos to MP4?
Convert them in the same pass that fixes the dates, so the new files keep the right timestamps.
Old home videos come in formats that modern players have quietly dropped: .avi, .3gp, .mpg, .wmv. Converting to MP4 makes them play on phones, smart televisions and browsers.
The catch is that most converters write a brand new file with today's date, so a converted archive ends up in one lump at the end of your library.
Takeout JSON Metadata Fixer converts and carries the original date across in the same step, so the converted videos land in the right year. It runs on your own computer and is free for your first 500 photos.
