Inserting a USB flash drive into your Vizio TV's USB input will initiate the option of playback. Once you've worked the right magic to have your USB device and files detected, your photos, music, and video content is then organized into sections, and displayed in a plain but useable string of thumbnails across the screen. Supported files and unsupported files will both show up, so there's no way of knowing whether or not a video can be played back at all. For those people who have downloaded some movies from online with MP4 file formats or captured a MP4 video with your camera, camcorder, smartphone or tablets, you may often feel confused that your Vizio TV even can't recognize your USB storage devices or you can play certain MP4 files from USB on Vizio TV but fail to play other MP4 files due to the unknown reasons. Never mind, the following article will illustrate those problems for you with helpful tips and solutions:

The usage for the USB port(s) on your Vizio television will depend upon the model.

If the USB port on your Vizio TV is capable of reading the multimedia file type, to let the MP4 file work properly on Vizio TV from USB, please follow the suggestions below:
- Make sure the drive is formatted to FAT32
- Use a USB drive that is 8GB or less
- Make sure that the file is Vizio TV USB port readable file format
- Reduce the number of files on the drive being used
- Reduce the size of the file (if possible)
- Try multiple files of the same format to verify that the initial file was not corrupted

If you do not want to lose any file quality, you can split the large file into small parts by file size, count or length or trim to cut off unwanted parts to leave only your wanted segments. If you do not care too much about output video quality, you can try the following ways to compress MP4 file with some quality lossage:

- Lower the bit rate 20-50% of the default to get small files
- Lower the frame rate of the video to 15 or 10 fps can reduce the file size by as much as 1/2 or 2/3
