Welcome to TestVid !

TestVid does just one thing: ‘Tvids’ - an unparalleled set of video test clips, designed specifically for

testing the quality of video encoders - also with audio!

Special test video

Tvids are not standard stock footage, but were filmed, edited and documented for the sole purpose of

evaluating video encoders.  They are designed to stress video encoders in many ways, by providing a wide

range of subjects including 'difficult' video such as fast movement, reflections, lots of detail, night-time,

highlights, hand-held camera, varying focus, varying contrast..

• Mobile, web, SD, 720p, 1080i, 1080p, 2K & 4K D-Cinema
• 3D stereoscopic - see T3D003 Europe, T3D002 USA West,
  T3D007_Asia and T3D023 USA Europe   3D sampler video
• 8 / 10 / 12 / 14 bit
• 4:2:0, 4:2:2, 4:4:4

Whatever you need, we have it.  (Plus of course, the audio that goes with the video.)

By compression experts, for engineers

Tvids were all produced by personnel expert in video compression, understanding what can be hard or slow for an encoder to deal with and what can take an inefficient encoder a lot more bits to encode.  To aid the engineer user, every clip is extensively documented - 70 features are noted, such as scene content, global and subject motion, colors and contrast, properties such as focus & depth-of-field and sound.  This makes it easy for a user to find the clips that contain grainy night-time video, or water, or text, or whatever the video type is that causes the encoder trouble.

Why use Tvids?

Tvids were designed both for encoder users - such as broadcasters - and for encoder developers, to give full test coverage of just about any type of video feature that an encoder is likely to encounter - in sequences which you can freely use for demos / trade shows / on your website.

For example, Tvids are great for a broadcaster who has to decide which encoder to buy, or if the latest software upgrade to their current encoders really is an upgrade.  Or is maybe experimenting with D-Cinema and needs content to try.

Or a development engineer who needs a wide range of defined-content video to try at different resolutions, or to know if the encoder slows down to less than real time when dealing with a lot of detail or a fast zoom, or any of a host of other video issues.
