Frequently Asked Questions

How do I make an MKV file smaller?


1. Select your MKV file and upload it to VEED

2. Adjust your compression settings

3. Export and save

4. Share

Why are MKV files so big?


An MKV file is typically larger than an MP4 because it can contain multiple audio and subtitle tracks. You may notice that when you save a video as MKV, you will end up with a larger file size than when you save the same video as MP4. 

How do I convert from MKV to MP4?


VEED automatically converts your MKV videos to MP4 format after compression. You can also convert your MKV files (without compressing them) by uploading to VEED and simply hitting the ‘Export’ button.

Will I lose image quality if I convert my MKV file to MP4?


No. Converting an MKV file to MP4 will not result in loss in image quality. Both MKV and MP4 are ‘container’ formats which means they can ‘contain’ and play the same video and audio in the same resolution.

How can I send a large MKV file via email?


Mail servers tend to limit the file attachments you can send between 20 and 25MB. It’s best to compress your MKV videos before sending them. 

Can I change bitrate, frames per second (FPS), resolution and CRF?


If you’re looking for a more advanced set of options, and you wish to control CRF, bitrate, resolution and FPS, then simply click on ‘Advanced Settings’. In this menu you will be able to adjust the video compression options to your exact specifications. Under ‘Resolution’ you will be able to choose from 480p, 720p, 1080p, 4k and more.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

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!
Quotation Mark - What they say about VEED

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.

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.
