Generating personalized videos with customized text messages

A computing device comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, configure the computing device to:
• receive a video template including a sequence of frame images, a default text, and at least one parameter for animation of the default text across the sequence of frame images;
• provide a user with a first option to replace the default text with an input text;
• in response to receiving the input text, generate, based on the input text and the at least one parameter for animation, a configuration file including a plurality of parameters for rendering an output video, the plurality of parameters including:
• a text style for the input text for a frame in the sequence of frame images;
• a position for the input text in the frame;
• and
• a predetermined number of text lines for the frame;
• split, based on the configuration file and a length of the input text, the input text into the predetermined number of text lines;
• render, based on the configuration file, a plurality of output frames of the output video, an output frame of the plurality of output frames including the frame in the sequence of frame images and a layer, the layer including the input text stylized based on the text style and placed at the position and in the predetermined number of text lines, wherein:
• the input text includes a text message;
• the text message is rendered unchanged in each output frame of the plurality of output frames of the output video;
• and
• the text style and the position of the text message change in the plurality of output frames of the output video based on the plurality of parameters included in the configuration file;
• play back the output video;
• while playing back, provide a user with a second option to change the at least one parameter for animation;
• and
• upon receiving an indication that the user has changed the at least one parameter for animation, dynamically change, in the output video, the position of the input text in the output frame according to the at least one parameter for animation.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that, when executed by a computing device, cause the computing device to:

• receive a video template including a sequence of frame images, a default text, and at least one parameter for animation of the default text across the sequence of frame images;
• provide a user with a first option to replace the default text with an input text;
• in response to receiving the input text, generate, based on the input text and the at least one parameter for animation, a configuration file including a plurality of parameters for rendering an output video, the plurality of parameters including:
• a text style for the input text for a frame in the sequence of frame images;
• a position for the input text in the frame;
• and
• a predetermined number of text lines for the frame;
• split, by the computing device, based on the configuration file and a length of the input text, the input text into the predetermined number of text lines;
• render, based on the configuration file, a plurality of output frames of the output video, an output frame of the plurality of output frames including the frame in the sequence of frame images and a layer, the layer including the input text stylized based on the text style and placed at the position and in the predetermined number of text lines, wherein:
• the input text includes a text message;
• the text message is rendered unchanged in each output frame of the plurality of output frames of the output video;
• and
• the text style and the position of the text message change in the plurality of output frames of the output video based on the plurality of parameters included in the configuration file;
• play back the output video;
• while playing back, provide a user with a second option to change the at least one parameter for animation;
• and
• upon receiving an indication that the user has changed the at least one parameter for animation, dynamically change, in the output video, the position of the input text in the output frame according to the at least one parameter for animation.
