If you edit your video to remove noise sounds or unwanted elements and upload it with the same title and description as the old video, it may have some effects, but they would largely depend on the context and platform you are uploading it to. Here are a few considerations:
Impact on existing viewership: If the video has already gained significant views, likes, and comments, uploading an edited version with the same title and description may disrupt the existing engagement. Viewers who have watched the original video might find the changes unexpected or confusing, and this could affect their perception and engagement with the updated video.
Search engine optimization (SEO): If the original video has been indexed by search engines, the edited version may not have the same visibility initially. Search engines rely on various factors, including title, description, and engagement metrics, to determine the relevance and ranking of a video in search results. Uploading a new version with the same title and description may require time for the search engines to recognize the changes.
Notification and subscriber impact: If your video has subscribers who receive notifications for new uploads, they might not receive a notification for the edited version, assuming they have already seen the original. Subscribers might expect new content when they receive notifications, so uploading an edited video without clear communication may result in lower engagement.
To navigate these considerations, it's generally advisable to communicate with your audience about any significant changes to a video. You can include a brief explanation in the video itself, update the title and description to reflect the changes, or provide a comment or pinned message explaining the update. This way, viewers can understand the reason for the re-upload and appreciate the changes you've made.
Ultimately, the effects of uploading an edited version of a video with the same title and description can vary, so it's essential to assess your specific situation, consider your audience's expectations, and communicate effectively to minimize any potential confusion or disruption.
