All completed movies I create in Android DJI Go 4 Editor using 720p video cache files contain audio synch problems and glitches/skips when played locally on the Android device (from the "production" folder), and also when uploaded and streamed from YouTube. But, these same movies play smoothly and have proper AV synch streaming from Skypixel.
Here's a recent example, notice the YouTube video suffers multiple glitches, and by the end the scene transitions are out of synch with the music. When streaming from Skypixel, it looks fine.
DJI Support, can you please comment if this is a known issue? I have never been able to have a DJI Go 4 movie stream nicely from YouTube or other sites other than SkyPixel.
