1. Re-recording: If time permits, you can re-record the video resume to ensure a better recording effect. Before re-recording, you can do some preparatory work, such as preparing the content, dressing neatly, cleaning up the environment, etc., to ensure that the new recording will be more successful.
2. Edit and Trim: If re-recording is not easy or feasible, you can try to trim and edit the original recording with video editing software. You can delete unnecessary parts and adjust the brightness, contrast or color of the picture to improve the video quality.
3. Supplementary subtitles: If there are some irreparable problems in the recorded video, you can consider adding subtitles to the video resume. Text description can make up for the defects in the video, and introduce personal information, work experience and other important contents in detail.
