Videos are not played, I upload the PC to the phone?

Hello,

I worked on Windows Movie Maker videos that I pulled after saving on my phone. It will show directly that the video may not play and if I want to copy it anyway. And then the video can't actually be played on my phone.

I have a new phone and my old cell phones have always worked. Have now the Huawei P20 Lite before Samsung and Motorola.

What do I have to do to make it work anyway? Is it due to the narrower display? Are there any other possibilities?

Maybe you can help me. Until then, thank you and best regards!

Looks like the file is corrupted, try uploading it to any cloud and then download it by mobile phone, otherwise I'll know how to continue net.

Thank you for your prompt reply. Have the video uploaded via onedrive. Could then watch the video, but when I downloaded it to my phone, it was the same again. Too bad. Otherwise I try out other clouds. Lg
