Videos keep going forward and backward randomly

[AC Question]

I have an android tablet 5.1 and when I play a downloaded video on any video player it start playing and like every 5-10 sec it flash some frames from past seconds on the video, but audio is perfectly fine.

I´ve tried cleaning cache
Restarted device
Unpluged and plgued SD
move video to internal storage
and nothing seems to work

Video is in mp4 and it works perfectly on my pc and my phone, also I've tried moving video from tablet to pc bc I think it could ve damaged while transfering it, but it still works perfectly on the pc.

Welcome to Android Central! Which device? Where are you downloading the videos from? Does this happen with videos you take with the device or with your camera? Are these videos being saved to Internal Storage or the SD card?
