MKV stands for Matroska Video—which was first developed in Russia in 2002.

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

What they say
about VEED

Veed is a great piece of browser software with the best team I've ever seen.

Veed allows for subtitling, editing, effect/text encoding, and many more advanced features that other editors just can't compete with. The free version is wonderful, but the Pro version is beyond perfect. Keep in mind that this a browser editor we're talking about and the level of quality that Veed allows is stunning and a complete game changer at worst.

The Best & Most Easy to Use Simple Video Editing Software!

I had tried tons of other online editors on the market and been disappointed. With VEED I haven't experienced any issues with the videos I create on there.

It has everything I need in one place such as the progress bar for my 1-minute clips, auto transcriptions for all my video content, and custom fonts for consistency in my visual branding.
