Abstract: A method and device for video editing. The method includes: obtaining a first video draft generated by a first client, which includes first editing capability information supported by a first client but not supported by a second client; performing an editing operation on a first video clip based on the first editing capability information to obtain the second video clip, whereby the first video clip and the first editing capability information overlap on the video editing time line; replacing, in the first video draft, the first video clip with the second video clip, and deleting the first editing capability information to obtain the second video draft; and providing the second video draft to the second client.

Abstract: A chaos engineering experimentation method for a system, a device and a storage medium. Minimum experimental traffic of a service request required by a chaos engineering experiment is determined as target service request traffic; service request traffic is adjusted for a canary cluster in a to-be-tested server cluster according to the target service request traffic, where the canary cluster is a cluster formed by servers in the to-be-tested server cluster, the servers being used for canary release when a service is upgraded; an experimental task of the chaos engineering experiment is executed in the canary cluster, and an experimental result is outputted. The chaos engineering experiment is conducted on the canary cluster, and the service request traffic of the canary cluster is adjusted to the minimum experimental traffic of the service request required by the chaos engineering experiment.

Abstract: The present invention provides a method a device and a system for processing parallel services, which includes: determining, by a synchronization locking server, whether a service request for locking is locked after receiving a locking request sent by a service server, and locking the service request when the service request is unlocked and returning a locking success response to the service server, or returning a locking failure response to the service server when the service request is locked, so as to ensure accuracy of a processing result of the parallel services that are processed across the cities, IDCs or servers.
