Legal analysis: witnesses are needed to record wills. A will made in the form of video should be witnessed by more than two witnesses, and its legislative intention is to ensure the authenticity of the recorded will. Testament witness refers to the third person who makes a will for the testator and can prove the authenticity of the will. There are six ways to make a will: writing a will yourself, entrusting others to write a will, printing a will, recording and video recording a will, notarizing a will, and making an oral will. Among them, except for self-made wills and notarized wills, the other four should be witnessed by more than two unrelated witnesses.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 137 If a will is made in the form of audio and video recording, two or more witnesses shall be present to witness it. The testator and the witness shall record their names or portraits, as well as the year, month and day by audio and video recording.

Article 140 The following persons shall not be witnesses to the will: (1) persons without civil capacity, persons with limited civil capacity and other persons without witness capacity; (2) Heirs and legatees; (3) People who have an interest in the heirs and legatees.
