MP4 Player gives you the ability to play files in MP4, FLV, and WebM video format on your Windows machine anytime without the need for a conversion first. It's nothing fancy, but if all you want to do is watch videos in their supported formats through a convenient interface, this is a good option.
Smooth playback: All videos we tested through this app played clearly and smoothly, without long loading times or other issues. We tested videos in all of the supported formats and found no issues playing any of them.
Playlist options: In addition to playing individual videos, you can also create a playlist from the videos on your computer and then let it run without needing to constantly go back and choose a new video to play. Adding videos to playlists is straightforward as well, and you can even add the contents of an entire folder at once.
Opening from URL: There is an option to open videos straight from a URL, as opposed to opening files already downloaded to your computer, but this feature didn't work during our testing. We attempted several times to paste a video URL into the appropriate field, but once we completed the process, the app just went back to a blank main screen.
MP4 Player is a competent program, and while it doesn't include a lot of bells and whistles, it does offer quality playback and a convenient interface. It's free to try for 10 days, and the full purchase price is $29.99.
Editors' note: This is a review of the trial version of MP4 Player 3.7.23.
