Abstract: Provided are systems and methods for personalized videos featuring multiple persons. An example method includes receiving a user selection of a video having at least one frame with metadata that include a first location and a second location and receiving an image of a source face and a further image of a further source face, modifying the image of the source face to generate an image of a modified source face and modifying the further image of the further source face to generate an image of a modified further source face, inserting, in the at least one frame of the video, the image of the modified source face at the first location and the image of the modified further source face at the second location to generate a personalized video, and sending the personalized video via a communication chat.

Abstract: Provided are systems and methods for searching and ranking personalized videos. An example method includes receiving a user selection of a category from a set of pre-determined categories, selecting, from a pool of videos, a first subset of videos, where a first video from the first subset of videos is associated with the category and having a calculated value of a performance metric, selecting, from the pool of videos, a second subset of videos, where a second video from the second subset of videos is associated with the category and having an unknown value for the performance metric, generating, based on a predetermined rule, a third set of videos, where the third set of videos includes at least one video from the first subset of videos and at least one video from the second subset of videos, and presenting the third set of videos via a communication chat.

Abstract: Disclosed are systems and methods for template-based generation of personalized videos. An example method includes receiving a sequence of frame images, face area parameters corresponding to positions of a face area in a frame image of the sequence of frame images, and facial landmark parameters corresponding to the frame image of the sequence of frame images, receiving an image of a source face, modifying, based on the facial landmark parameters corresponding to the frame image, the image of the source face to obtain a further face image featuring the source face adopting a facial expression corresponding to the facial landmark parameters, and inserting the further face image into the frame image at a position determined by the face area parameters corresponding to the frame image, thereby generating an output frame of an output video.

Abstract: Systems and methods for providing personalized videos are provided. An example method includes receiving preprocessed videos including a target face and facial expression parameters of the target face, modifying the preprocessed videos to generate one or more personalized videos by replacing the target face with a source face, where the source face is modified to adopt the facial expression parameters of the target face, providing a user interface enabling a user to share at least one personalized video of the one or more personalized videos with a further user of a further computing device, determining that an application to be used to share the personalized video does not allow auto-play of the personalized video in a video format, in response the determination, exporting the personalized video of the one or more personalized videos into an image file, and sharing the image file via the application.

Abstract: Described are systems and methods for generating personalized videos with customized text messages. An example method may commence with receiving a video template. The video template may include a sequence of frame images and preset text parameters defining an animation of a text. The method may continue with generating a configuration file based on the text and the preset text parameters. The configuration file may include text parameters defining rendering the text for each of the frame images. The method may further include receiving an input text and rendering an output video comprising the sequence of frame images featuring the input text rendered according to the text parameters. The rendering may be performed based on the configuration file. The method may continue with sending the output video to a further computing device via a communication chat.

Abstract: An example method for searching and ranking personalized videos commence with receiving a user request via a communication chat between a user and another user. The user request includes a phrase or emoji. The method performs, based on the user request, a search of a pool of personalized videos to determine a subset of relevant personalized videos. The personalized videos are associated with text messages. The method further includes determining first rankings of the relevant personalized videos. The method then proceed with selecting, based on the first rankings, a pre-determined number of personalized videos from the subset of relevant personalized videos. The method then determines second rankings of the selected personalized videos and present the selected personalized videos within the communication chat in an order based on the second rankings. The personalized videos of the first subpool and the personalized videos of the second subpool are ranked independently.

Abstract: Disclosed are systems and methods for providing personalized videos featuring multiple persons. An example method includes receiving a user selection of a video having at least one frame with at least a target face and at least one further target face and receiving an image of a source face and a further image of a further source face. The method further includes modifying the image of the source face to generate an image of a modified source face and modifying the further image of the further source face to generate an image of a modified further source face. In the at least one frame of the video, the target face is replaced with the image of modified source face and the at least one further face is replaced with the modified further source face to generate a personalized video. The personalized video is sent to at least one further user.
