![]() Not every scene gets animated, but strategically, you can animate some parts of it to make it more engaging to the viewer and to highlight certain parts of the message.Įven though its evolution from paper (or whiteboard!) to digital animation suffered, the three main elements we discussed earlier still remain. This makes the style more polished and clean, and it’s also faster to produce… and any mistake can be solved instantly without having to start over.ĭigital hand-drawn animation videos also introduced animated characters and situations to this style, which was something that couldn’t be done before! Gladly, nowadays the process is much more time and cost-effective because by now it’s all made digitally. On top of that, if the artist made even the tiniest mistake, it couldn’t be solved and they had to film it all over again! Of course, the classic style of animation translated into lots of time and effort, and also, in most cases, a very poor result. Also, some special effects were added, to give the style a boost (which also helped achieve a high-quality result!). As the years went by (and the technology improved), the technique was improved and empowered with 2D animation. Originally, these videos were drawn in real life, by an artist that was being recorded with a camera. Classically, it’s made out of a whiteboard background (or another kind of background that could serve to draw on, like a piece of paper), a continuous drawing, and a hand that draws.īecause of their popularity, you’ve probably seen them before! Let’s take a look at the basics of this video style. With an orientation+position keyframe at the first frame (red) and a position keyframe at the last frame (green), our system renders the corresponding canvas coherently throughout the video.Marketers love them! Because these videos give them the chance to explain a complex business idea in just a few seconds, in a highly educational way.īut what makes these videos unique is their style – they have a very recognizable animation style which makes it highly attractive to an audience. ![]() From user intent expressed through an arbitrary number of position and orientation keyframes, our algorithm can render a scene-aware canvas at any frame of the video with correct occlusions, perspective transformation and make the canvas follow a moving object. In a nutshell, we introduce a novel UI and tracking algorithm to unlock new edition capabilities for videos augmented with depth and motion data (obtained via existing computer vision methods). Our system takes care to interpolate keyframes by tracking the motion of moving objects in the video. Users can finely control the canvases with in our 2D image-space UI by keyframing position and orientation. ![]() The user draws animated doodles onto this canvas. In our system, the final frame is obtained by rendering our scene-aware canvas in a partial 3D reconstruction of the captured scene. We propose to assist the creation of video doodles with a user interface that leverages depth and motion priors to anchor scene-aware canvases in the captured video, onto which users can add hand-drawn frame-by-frame animations. The main difficulty faced by artists following this manual workflow is to make the drawn content interact convincingly with the video content. ![]() ResultsĪrtists typically create video doodles by drawing 2D animations frame-by-frame, using the video as an underlay. ![]() When testing our system, novices could create a variety of short animated clips in a dozen of minutes, while professionals praised its speed and ease of use compared to existing tools. Furthermore, we present a custom tracking algorithm that allows users to anchor canvases to static or dynamic objects in the scene, such that the canvases move and rotate to follow the position and direction of these objects. Our system supports these effects by relying on planar canvases that users position in a 3D scene reconstructed from the video. In particular, the drawings should undergo tracking, perspective deformations and occlusions as they move with respect to the camera and to other objects in the scene – visual effects that are difficult to reproduce with existing 2D video editing software. Video doodles are challenging to create because to be convincing, the inserted drawings must appear as if they were part of the captured scene. We present an interactive system to ease the creation of so-called video doodles – videos on which artists insert hand-drawn animations for entertainment or educational purposes.
