I was runin out of battery, I landed the drone, I turned off it, but i did not stop the video recording on my dji go4 in my cell phone. I found the video file in the SD card, together with all previous clips, bat that last one has more than 2.4 GB, has a name: DJI_0006.MP4 and i found the DJI_0006.THM file olso in the SD, but the duration shows 0:00 seconds, and i looks like the file was never finished, so I can not play it.

How can play it?, or how can I finished the clip...? or is ther any way that I my recover that clip. Please help me.
Also I look into my phone, and it is there.  but with low resolution and with sound and video unsyncronized...

djifix from djifix.live555.com can parse broken mp4s and creates new files with h264 extension

try putting the card back in and restarting everything and it should fix it.  

On Linux , untrunc helped me: https://github.com/ponchio/untrunc

(The files have wrong framerate now, but that can be fixed in editing)

Im glad to hear that.  Thanks

I forgot to stop my videos twice before turning off the Spark and I can play those video files without problems. The videos play all the way up and until I turn off the drone. Maybe the latest firmware fixed it.
