How to use Keyframes to animate effects and create custom transitions in Enlight Videoleap for iPhone «iOS & iPhone :: Gadget Hacks



One of the most powerful features in editing videos with Enlight Videoleap is the Keyframe tool that lets you add your own transitions, animate text, adjust the sound correlated, moving video clips over the frame, supplementing effects and more. If you want your video to change color over time or for captions to move across the screen, use key images in combination with Videoleap's other tools.

If you are new to video editing, key images can be a tricky thing to get used to, but learning how they work will give you almost endless possibilities to fine-tune both video and audio layers. Videoleap has lots of editing tools, and you can use all these tools along with key images for total customization. A sequence of key images determines how long the effect takes place, while the number of key images in that sequence determines the movement and other changes.

Step 1
: Get Your Project Ready

Make sure you have updated "Enleap Video Leap Video Editor" on your iPhone, as developers are continually adding new features and fixing bugs. If you already have a project open that you want to try key images on, proceed to step 2. Otherwise, you add some media to a new project.

Touch the red and white plus sign on the timeline, and select a video from an album in your app in Photos, from the cloud in the Files app or from the Videoleap stock option, which has a good amount of free videos to play with. Once you have added a video or two (or how many) you can immediately add key images to those clips or you can add some effects to animate, such as green screen movies or captions.

Step 2: Add some keyframes

Before we find out which key images can be done for you in terms of animations and effects, you need to know where the keyframe icon is and how to add and delete key images from your project. Start by tapping on a clip or effect in your project, which will change options on the lower toolbar. Over the toolbar to the right you see a diamond icon with a plus sign above it – it is the keyframe tool.

Touch the keyframe tool to add a keyframe marker to your clip. You just made your first keyframe, which tells the app you want the video, sound or photo to have the same settings as it already has up to the specified time. It will also be the beginning of your animation or change.

Move the playhead forward on the selected clip and press the keyframe icon to add another cursor to your clip. If you just add a second keyframe, it will be the end of your animation or change. With this keyframe selected in the clip, you can make changes with all available tools. When you play the clip, the video, sound or photo will play as usual, and at the first keyframe, it will begin to transition to the effect you applied to the second keyframe, but it will not become full until the game head hits the second keyframe.

It is the basics to add key images. Of course, you can have as many key images as you want for each key frame, which is sequenced, depending on how elaborate you want your animation to change to be in the entire clip.

If you want to get rid of a marker, press it, then the keyframe icon, which now has a minus sign. You can also use the back tool (far left above the toolbar) if you make a mistake. Getting rid of a marker is important to know because there is no way to move a marker, but you can remove one and place a new one.

As you soon see you do not need to Always add keyframe markers to the video clip manually. Once you have created one, move the playback head and then make a clip setting, a key frame is automatically added.

Step 3: Animating effects with key images

Now that you know how to put down keyframe markers, it is time to see how they work with effects. You can use keyframes to move through filters, change opacity, make speed adjustments, use different color tones, move text around your entire video and change the volume, to name just a few.

For this example, I will create different color tones for specific parts of a video, but you can do this with effects for audio clips and photos. I also start from the beginning, without any key images in the clip, so I can show you the other way to add additional keyframe markers.

Begin by pressing the clip and then moving the playback head to what you want the first keyframe cursor, then press the keyframe tool to add one. Next, with the clip still selected, move the playback head to the location you want the next key frame, but do not add one.

Since we change the hue in this example, click "Adjust" in the toolbar, then press the "Hue" option. A slider appears above the toolbar, so use it to adjust the hue to where you want it. As soon as it goes above or below zero, a new keyframe will automatically be added.

You can also set the markers in advance and change the hue after printing each, but the automatic keyframe option feels more intuitive. Just know you have options! You can continue moving the game head down the clip to add more shades, ie more key images, until you are satisfied. Use the keyframe deletion icon or the back button to set up new markers if you make a mistake.

When you finish adding keyframes, play you to watch the video to see if you like the effect. Videoleap automatically creates a transition for you between keyframes. The closer the markers are to each other, the faster the effects change. The farther away, the longer the transition takes. Play around with distance to see which transition you like best. Below is what my video looks like with several keys in different keywords.

If you create key images for text and move the text around with your finger, the animation becomes the path between the original location and the new location. For example, you can place text in the middle of the video, set a keyframe marker, move up the timeline, and move the text to the top right to automatically set another marker. During playback, you see the path animation of the text you moved.

Each editing tool reacts differently key images, so playing is the best way to see how the results will look. This guide was just a starting point for getting started and finding ways to be creative with it.
