Systems, methods and graphical user interfaces for motion editing and animation applications

A first electronic device comprising:

• one or more processors;
• memory;
• and
• one or more programs stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for performing a method comprising:
• presenting, at the first electronic device, a computer-generated environment including:
• a representation of a second electronic device, wherein the second electronic device is in communication with the first electronic device, and wherein the second electronic device is running a content creation application;
• and
• an animation user interface associated with the content creation application, including:
• a first object having a first pose;
• and
• a first user interface element including an animation timeline;
• while presenting the computer-generated environment at the first electronic device, receiving, at the first electronic device, a first input corresponding to movement of the first object from the first pose to a second pose, different from the first pose;
• in response to receiving the first input:
• updating display, in the computer-generated environment, of the first object to have the second pose;
• and
• transmitting, to the content creation application running on the second electronic device, data corresponding to the movement of the first object from the first pose to the second pose.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of a first electronic device, cause the first electronic device to perform a method comprising:

• presenting, at the first electronic device, a computer-generated environment including:
• a representation of a second electronic device, wherein the second electronic device is in communication with the first electronic device, and wherein the second electronic device is running a content creation application;
• and;
• an animation user interface associated with the content creation application, including:
• a first object having a first pose;
• and
• a first user interface element including an animation timeline;
• while presenting the computer-generated environment at the first electronic device, receiving, at the first electronic device, a first input corresponding to movement of the first object from the first pose to a second pose, different from the first pose;
• in response to receiving the first input:
• updating display, in the computer-generated environment, of the first object to have the second pose;
• and
• transmitting, to the content creation application running on the second electronic device, data corresponding to the movement of the first object from the first pose to the second pose.
