Video/Audio Lag

[Kartik Chopra]

Hello All, looking for some help here,

I have 3 mobiles, a Karbonn sparkle v, a Moto G4, and a lumia 950xl

When I play a 720p TV show on all three mobiles, I have noticed the Karbonn sparkle v plays back without fuss, the Moto G4 has very short lag in either video or audio (for a second or so and then it goes away), also there is grey stuttering of video for a short period sometimes, and the lumia plays the video better than the Moto G4 but too has very small issues with video/audio lag.

A Laptop with integrated Graphics plays it fine.

 

As the specs go, the videos are played back from an SD card (class 4 on the sparkle v and class 10 on other mobiles) and the videos are played back on VLC (I have tried other players with little to no improvement)

Am I doing something wrong, if the sparkle v can play a video, all three mobiles should play it. I have played YouTube 4K rips smoothly on the lumia.

Please help.
