downloaded video is choppy and laggy

I have a solution! Basically go to files right click on your keypad then u should see a tab of options. Click the one that says “open with” click the option that says photos as it takes you there save the video on files you can also trim it so it’s easier and the once you save it, it lets you change the format for example if the file is in mp4 it lets you change the file to any supported file. So that you are able to see the download video. This happens because the video may not be supported in what ever app or program you’re trying to use to open it. Or In some cases, a choppy or laggy video could be caused by an error that occurred during the download process. For example, part of your MP4 movie or 4K film file might not have been downloaded correctly or could be corrupt. Re-downloading the videos might be a simple way to fix choppy videos on your device.
