Easy Updates: When we needed to change a video, we just edited the text. We didn’t have to re-shoot the whole thing. This saved us so much time.
Simple Translation: We have offices in different countries. We could make one video and then translate it into other languages with one click.
一貫した外観: We used the same AIアバター for all our videos. This made all our training videos look the same and feel like they were from our company.
Better Teamwork: Our team could work on the same video at the same time. We could leave comments and make changes together, which made our work better and faster.
