Blue Background Animation

[Doria Vilcan]

Imust be doing something wrong, because when I have my two frames with the adequate changes between the two, I click tweens on the frame timeline and then deselect opacity, I made sure to choose to tween with the next frame, and then I click okay. Photoshop doesn't tween for me, there is no slow change from one image to the next:

I'm not trying to animate the blue background, I'm trying to animate the clouds moving across the screen slowly. And when I have the opacity parameter turned on, Photoshop's tween effect looks strange. I suppose I expected something different, but this just must be the way Photoshop tweens. Thank you for your response

You are making tween! It's OK but you didn't change anything from frame 01 to frame 02.

You should make the main keframes first, make changes in Position, Opacity or Layer Style between the main frames.

But tween can't make animation for the same frames.

I was not careful about placement. I'm sure you'll know that with the gradient, you'd need a decent colour depth to avoid banding. I got away with 128 for the example below. That has produced a 400k file size with 200 frames, and it still pretty jerky.

Can you indicate what you think is happening with your animation? Perhaps upload the resulting GIF. At the moment I can't see any issues from your screen shots. Does your workflow roughly follow what I have described above?

Still a bit slow, but reasonably smooth for a frame animation. Strangely, the smoothest looking frame animations are those with either very slow, or very fast movement. With the latter, the eye fills in the gaps, so to speak.

Reveal supports a number of animated transition effects for both slide changes and slide background changes. By default no transitions are used, however you can enable them either globally or per-slide using the options described below.

When preparing a presentation it can sometimes be helpful to prepare optional slides that you may or may not have time to show. This is easily done by appending a few slides at the end of the presentation, however this means that the Reveal progress bar and slide numbering will hint that there are additional slides.

Reveal will automatically scale presentations uniformly based on the normal size to ensure that everything fits on any given display or viewport without changing the aspect ratio or layout of your content.

The absolute class lets you position elements at arbitrary positions on a slide. These elements have CSS position: absolute and can be placed relative to the top, left, bottom, and/or right edges of the slide.

The following attributes can be used with absolute. All of these values can be specified in CSS units (e.g. px, em, etc.). If a number with no units is specified (as in the above example) then pixels are assumed.

The center class when applied to a slide, will vertically center the slide content by adding the appropriate spacing at the top of the slide. Vertical distances between elements will not be modified. For example:

The r-stretch layout helper lets you resize an element, like an image or video, to cover the remaining vertical space in a slide. For example, here the image will automatically be resized to fit space remaining outside of the slide title and text before and after it:

Revealjs can automatically animate elements across slides. All you need to do is add the auto-animate attribute to two adjacent slides and Auto-Animate will animate all matching elements between the two.

This example uses the margin-top property to move the element but internally Reveal will use a CSS transform to ensure smooth movement. This same approach to animation works with most animatable CSS properties meaning you can transition things like position, font-size, line-height, color, background-color, padding and margin.

Animations are not limited to changes in style. Auto-Animate can also be used to automatically move elements into their new position as content is added, removed or rearranged on a slide. All without a single line of inline CSS. For example, here the delta between the content on two slides is implicitly animated:

In situations where automatic matching is not feasible you can give the objects that you want to animate between a matching data-id attribute. We prioritize matching data-id values above our automatic matching.

You can override specific animation settings such as easing and duration either for the whole presentation, per-slide or individually for each animated element. The following configuration attributes can be used to change the settings for a specific slide or element:

Multiple fragments can be applied to the same element sequentially by wrapping it. The following example will fade in the text on the first step, turn it red on the second and partially fade out on the third:

By default fragments will be stepped through in the order that they appear in the DOM. This display order can be changed using the fragment-index attribute. Note that multiple elements can appear at the same index:

By default these controls appear at the edges of the presentation, you can position them in the bottom right corner using the controls-layout option. You can also provide an extra visual cue to viewers that the controls are available using the controls-tutorial option. For example:

To use Revealjs plugins, you need to package them into a directory with a config file (plugin.yml). The config file lets Quarto know how to inject the plugin into the presentation (e.g. what scripts and/or css files to include, what the default configuration should be, etc.).

Download the plugin files into the created folder. Here the plugin only have a JS file called plugin.js that you can find on the repo rajgoel/reveal.js-plugins. You can keep the name or rename it, e.g fullscreen.js.

The custom plugin will be loaded in your presentation and you can use it. The plugin fullscreen documentation shows an example of adding a Map fullscreen in a slide by adding an attribute on the section, and using stretch on the content. This would translate to having this slide in the .qmd file:

You can set a transparent background under Render Settings > Film > Check Transparent.

But keep in mind that not every format supports an alpha channel. So you might be better of rendering a .png or a .exr image sequence.

You should be able to pull an image sequence into your video editor as a movie. That said, Blender is great for this sort of thing. That tutorial I linked to above is ALL blender apart from the initial green screen of the actress. Removela of markers, greenscreen and compositing is all done within Blender.

Should behave exactly the same as in Blender I would of thought. I did this in Serif Photoplus just now, using a couple of layers of transparent particles with glow on one of them and varying opacity. The blue background is a separate layer, as is the logo.

If the subject of your video is green or is wearing green, you should record in front of a blue background. Likewise, if the subject of your video contains blue or is wearing blue, you should record in front of a green background.

The audio from the original clip and the audio from the green-screen or blue-screen clip play simultaneously. You can reduce the volume of either clip so that sound from the other clip stands out. For more information, see Add audio effects in iMovie on Mac.

One of the reasons filmmakers moved from blue to green screens is because digital cinema cameras record more color information in green. However, USB cameras process video differently, and we weren't totally sure what to expect going into these tests. Here are the results.

We grabbed a frame from the 720P and 1080P camera with both a green and blue background. Then on Windows we ran the frames through WMM 6.0 with the Rehan ShaderTFX plugin applied, and on OS X we used iMovie with the Chroma-Key effect applied.

I want to colour this background, say with white. Unfortunately I could not generate it, nor with the filling tool, nor with the context menu. finally I draw a white rectangle of the same size as the canvas.

I want, that the colour of the backgound is slowly changed while the animation is running, say to light blue after 5s. Is that impossible? At the 5s point I changed the colour of my rectangle to light blue, but now the colour is applied already at 0s. There is no colour transformation.

MICA uses multiple bold background colors, although the bright blue is used most often since it matches the MICA logo and brand. The background changes as the user scrolls, making the experience more dynamic.

PHOTON incorporates blue into its black and white website design to showcase its company and product in a clear, bold way. This color scheme is ideal for presenting a complex product in an engaging way without overwhelming visitors with information or color.

Bridge uses a sophisticated color scheme of navy blue, white, and teal to reinforce its brand identity as trustworthy and contemporary. This navy blue website also uses a stark white for its text, forms, images, and other important elements so they stand out.

Since Ville de Sorel-Tracy is known for its skating rinks, swimming pools, and river that runs across the city, navy blue is a fitting color for this website. It cleverly alternates between using navy blue as the background color and the accent color, depending on how text-heavy the section is.

VTB Digest actually uses multiple color schemes. When you first land on the homepage, you see pastel complementary colors. But as you scroll, the website design changes and incorporates navy blue, bright blues, and lighter shades as well. All of these shades of blue are ideal for a banking site that wants to evoke feelings of trust and confidence.

This color scheme is ideal for innovative companies in tech and other industries. Use the ebony and iron colors as your background and text colors, and the blues for animations, navigation links, and more.

This color palette is a twist on the traditional black-and-white color scheme. The blue and black combination will make an unforgettable impression, while the pastels can help introduce warmth and balance.
