Is it better to use other advertiser’s videos to run Tiktok ads?
使用其他广告商的视频来投放抖音广告是否更好？
It's better to use your own video! using other people's creatives to promote your product without their authorization means that you’re infringing in their copyright! It's possible to face a DMCA takedown notice or even a lawsuit if you’re infringing on other people's copyright. Aside from obvious Copyright issues, there is the issue of ad fatigue. If a video has been seen multiple times by the same audience, people get tired from seeing that video. Ad fatigue reduces ad performance such as the video click through rate.  If you are using someone else creatively which they have overly promoted. You might experience a low ad performance.
最好使用自己的视频！未经他人授权使用他人的创意来宣传您的产品意味着您侵犯了他们的版权！ 如果您侵犯了他人的版权，则可能会面临 DMCA 删除通知甚至诉讼。 除了明显的版权问题外，还存在广告疲劳问题。如果同一个观众多次观看某个视频，人们就会厌倦观看该视频。 广告疲劳会降低视频点击率等广告效果。  如果你创造性地使用其他人，而他们已经过度宣传了。您可能会遇到广告效果不佳的情况。
