So i try to use the director editor and when i click on the cached videos it turns green and purple but the videos are good on sd card so i think its android malfunction so just seeing if anybody having the same problem.
I got an email from dji support.
They examined the videos i uploaded to their server.
It is an android problem on some devices (i use the samsung Note 4).
In the next pilot app version this problem will be sollved.
