I need to blend a video over the image, as done like in this example link:
https://hearthstone.blizzard.com/ru-ru
Where there is man with a beard and also a girl. The videos are blended with a background using what I suspect is a type of "lighting" blending mode.
Question:
Does anyone know how to achieve it with Elementor (a website creation tool)?
I've tried to find a setting in video container but there is no such option.

I think I understand the WCAG 1.2.5 Audio Description (Prerecorded) rule, but what I can't find a straight answer on is if what if the per-recorded background video provides no real value, like if it's just a short video of someone walking on a loop with no talking/audio. Does this rule still apply?
Short Answer
Assuming the video serves no purpose other than decoration then you are safe to hide it with aria-hidden="true".
Longer Answer
While the above is perfectly valid for accessibility, there are other considerations from an accessibility perspective.
Do you provide a way to pause the video? If someone has an anxiety disorder then the video can be distracting so you must provide a way to pause the video. (or you could use the Prefers Reduced Motion media query and use that to stop the video auto playing, however the support is not fantastic at 80%.)
You should also add the muted attribute to indicate that the video has no sound to screen readers.
If the video does provide a purpose (i.e. it emphasises what the company does) then you should add a description to the video using aria-describedby and pointing that to a hidden <div> with a description of the video contents as a minimum.
Final Thoughts
If the video is purely decorative, has no meaning within the page and is there just to 'look cool' perhaps consider replacing it with an image. It will massively help your page load times and so can only help with conversions, video backgrounds hurt more than they help as they take focus away from your call to action.
I'd like to have a background image in the NSSavePanel which I need to satisfy macOS Sandbox file export requirements. Such background image would be reflective of the overall imagery I use in the other application window and sheets. Apple's default NSSavePanel image style is okay for an app that cares little about its style, but my app is directed to video editors who can appreciate an artistic rather than mechanical atmosphere.
I've been able to use the panel's accessoryView property but it only appears as a differentiated section in the panel separate from the panel's overall style.
A simple background image for the panel overall capability would completely suffice, but it doesn't seem possible according to all the Apple Developer documentation. Maybe there's a practical HACK?
before I start I'm not a developer, so apologies in advance for any potentially daft questions. Our developer has just integrated a custom soundcloud player for our website http://www.samplephonics.com/ (see when you hover over the top 8 or recent sample packs) but I want to change the light grey background colour around the waveform to white.
As far as I am aware it's configured so that the light grey mask displays the shape of the waveform as a hole, which then has solid light grey, grey and dark grey images behind to show the apparent colour of the waveform in idle, loading and playing states..
Does anyone know how we can change this mask to white, or have any ideas I can send his way? He used this example as a starting point for creating the player: http://static.soundcloud.com/demos/soundcloud-custom-player/examples/sc-player-minimal.html
Thanks in advance :)
I've previously answered this here – https://stackoverflow.com/a/14731623/236135
unless the library you want to use for waveform customisation is using HTML5 canvas, you won't be able to use change the color of that chrome (so no, not possible with either HTML5 Widget API or Custom Player API)
In short, you'd have to use canvas or manipulate the images on the server and retrieve them from server.
I am working on a project where I would like to open a video (on a Mac) with QTKit. That part I can do no problem, but as I am playing it, I would like to edit or modify the video on the fly using OpenGL.
From what I understand, I should be able to intercept the frames and change them before it hits the display, but no matter what I do, I cannot seem to do so.
It sounds like you should have a look at Core Video and the display link mechanic.
You can basically get a callback on a high priority thread with the decoded frame in a CVImageBuffer and do whatever you like with it (including packing it up as a texture for OpenGL processing and display).
Apple provides documentation and demo code snippets on the developer sites.
I'm using the OSX QTKit sample code from here: http://bit.ly/mAaHGI
I'd like to crop the video, both on the screen and the saved file, to simulate different aspect ratios. What is the best way to do this?
It's a bit more involved than just calling a crop method, but Core Video allows you to manipulate the video stream. You can find the Core Video Programming Guide here:
