What are Digital Video Formats

Life was much easier, though not that convenient, during the analog video days.

You didn’t really have to worry much about video formats. As long as you had the right equipment to play your video content, you’re fine.

If you had a VHS tape, you played it with a VHS Player-Recorder and a S-VHS with a S-VHS player and so on.

The World of Digital Video

Enter digital video, which revolutinized the video production landscape with the introduction of optical discs (CD/DVD), flash drive and hard disk storage.

There are now at least a dozen popular video formats and a good number of little-known formats.

These formats came about mainly to accommodate size limitations of the different storage media.

Digital Video Format Versatility

Most digital video formats can be played back through hardware equipment – DVD, VCD, SVCD and all of them can be played through software media players over a computer.

The main aim of digital video format is to deliver video of high quality without using much storage space.

Digital video can be easily transmitted and doesn’t require bulky storage medium or hardware players like analog video (VHS etc).

Digital video can easily be copied quickly compared to analog video which must be copied in real time. A 2-hour VHS tape would take two hours to copy to another tape. A digital video file of the same length can usually be copied in minutes.

A digital video file, on the other hand, require only minutes and doesn’t need bulky equipment setup to replicate it.

A digital video file can be copied to a flash drive, hard disk drive, memory cards and even to cloud storage and be played back from there.
