Thanks for sharing. The file is actually saved to the micro sd card after the recording is stopped. So if you turn off the drone whilst still recording the current video file will be lost and yes, it can corrupt the whole card. Always ensure to stop record before turning off the drone as part of a post flight check.
Not quite. The file is an MPEG stream, meaning it is in effect a continuous file, it is not saved after the recording is stopped, rather when you lose power, or shut the aircraft down, the file is not 'finalised', which is a fancy way of saying the end-of-file information is not written to the file, sometimes this is referred to as 'finalising' the file. The aircraft firmware has a routine that can detect this when the system is initialised, so switching the aircraft back on again briefly will write the appropriate termination information and the file will become readable.
It would not normally corrupt the card, sometimes people do not stop recording before shutting down a number of times leaving a trail of unfinished files, which tends to make people think the entire card is corrupt. |
