It must be: Panasonic MDH 1.
Storage medium: SD card. An SD card with 16GB can be recorded for two hours (HD mode 1920* 1080), which is just enough for a wedding, so it's better to prepare another one just in case.
The original battery life is more than 4 hours (including standby and recording). If it's not enough, buy another one with a thickened battery life of 9 hours from the seller, and take both of them out to do the task, so the charger is free (slightly lighter when traveling).
Disadvantages: the shooting effect is not ideal indoors and at night, that is, in low illumination, so you need to buy another camera lamp. But the photos taken in the daytime and sunny outdoors are definitely worthy of the word "HD".
Note: The sum of all the outsourcing accessories and one package listed above will not exceed 10000. As long as it doesn't exceed 10 thousand, it will be used in wedding photography, which is guaranteed during this period! Highly recommended.
