Switch clips are both easier and better quality than some shaky camera footage. Obviously there is a concern for splicing however with runs that use an in game timer this shouldnt be an issue as there is no way to fake them in this way (unless its possible to TAS save states in switch games but then it would also be possible to record a tas without seperate clips). For a irl time run clips would make splicing easier and timing inaccurate but for in game timer runs i dont see the issue. If all clips are consistent with the previous and there is no gaps i think it is almost impossible for someone to fake them.
