HTML5 Video Editor release

29.08.2022 Olga Krovyakova 790 Comments Off

HTML5 Video Editor is the professional online video editing tool that can be embedded in your Media Asset Management System (MAM), Learning Management System (LMS), Newsroom or in Healthcare system.

The editor can work both in the cloud and on premise, as it integrates with existing systems.

What is especially significant, when editing the smart rendering technology is used.

It means your users no longer have to worry about the image quality of the resulting video, as it will remain the same as it was in the original file.

Since this editor is online, it is fast and efficient and, due to smart rendering technology used, reduces energy consumption and pollution of the planet, which has a beneficial effect on the carbon footprint.

If your customers want to cut and join one or several files, add audio to the video file, add pictures or transitions between video segments, add text overlay – this all is possible with HTML5 Video Editor.

We had been working hard on the editor and are happy to announce the official release of HTML5 Video Editor. Let’s tell you about some new interesting features.

Bucket name, Secret key and Access Key ID are used to control access to files.

For convenience, when there are a large number of files uploaded to Media, we have also added a search bar and filters to sort files into categories (video, audio files, pictures).

Video cut, join feature, rearrange of pieces of files, smart reencoding 


The editor allows you to cut video and audio files and preview the changes right away – delete unnecessary segments and save the rest.


If you want, you can also join multiple clips into a single file. Just place several clips one by one on the layer of the timeline and click the “Publish” button to merge them.



The rearrange of pieces of files at the timeline is also available.

While cutting or merging the smart reencoding is used. It means that used files for cutting or merging can be of different parameters.


To make your videos more attractive, we have added the ability to add different transitions between multiple videos or their parts.

Currently available transitions are: Fade In, Fade Out and Dissolve.


To add the transition to video select the “Transitions” section on the left of the editor, grab the required transition with the left mouse button and drop it into the necessary position –  between two files /  segments of a file, at the beginning or end of the specific file.

You can also adjust your transition. For this select the transition on the layer, it will be highlighted with the blue color, and click the “Settings” button as shown at the screenshot below.

Text and graphics overlay 

If you want to add the header, annotations or any text to your video file you can do this with HTML5 Video Editor.

Just select the “Text” tab on the left side of the editor, drag and drop the “Text” template to the timeline area and select the properties for your text: enter the text itself, select its position, color, size and other properties.

You can also overlay an image on the video. For this, upload your image to the Media list, then drag it with your mouse and put in the timeline area.

Note: the picture should be placed at the layer above the video, not under it.

You can set properties for your image as well. After you put the video to the timeline area’s layer, click on the image at the Preview area and you’ll see available image options at the Media area. The settings that can be changed include size, position, rotation, opacity and other. The PNG files with transparency are also supported.

Audio overlay

Adding an audio file over a video is one of the most popular tasks.

To add the sound to the video you need to do the following:
  • place the video file to the layer
  • select the audio file from the Media list
  • place it at the layer under your video file
  • click the “Publish” button to get the desired output file.

Moving Layers

If necessary, you can rearrange the layer moving them up or down within the timeline.

Simply use “Move Up” and “Move Down” buttons to control the layers position.

Support of MXF XAVC with pre-existed proxy files (demo mode)

MXF files are quite large and difficult to work with, and online are completely impossible to work with because the browser does not support them natively. Proxy file is a pre-encoded file with lower resolution that solves this problem. The feature is supported in demo mode.

Audio library

HTML5 Video Editor contains the audio library that allows to add music to your video. The music is grouped by genre and by mood, so you can select the best appropriate track for you.

You can also add some sound effects to your video.
