Video files can have extreme sizes depending on formats, resolution and quality settings. If you have ever captured a game video of a game running in 1920x1080 in 30 or 60 fps, you know that even short videos will reach the Gigabyte level quickly.

Deepnut is a free program for the Windows operating system that has been designed to process video files you add to the program's queue.

It is a simple program that requires no knowledge of technical terms like bitrate, aspect ratio, resolution, frame rate or other terms that you come across regularly in the video world.

It is as simple as it gets: load a list of video files that you want to convert to mp4 with a click on the video selection button that is displayed on the first screen of the program interface.

There you may also select a different output folder for the converted video files. The only configuration options the program provide are listed on that page as well.

You may move two sliders up and down that influence quality and file size of the resulting video files and the time it takes to process them on the computer.

A higher quality setting results in larger file sizes and longer processing time while the low quality setting speeds things up and produces smaller video files.

As far as file size is concerned, the author of the program reveals in a tooltip that high quality files will use about 20 MB per minute of playtime while low quality files only 6 MB.

The process is automated once you hit start afterwards. The program switches to the progress screen that highlights the total progress, successful and failed conversions, and the current file that is being processed from the queue of video files you have added to it.

So who is this for?

Deepnut is for people who want to convert video files to mp4 quickly without having to worry about setting the right bitrate and formats. The program supports the majority of input video formats thanks to its reliance on ffmpeg.

It is not for users who want control over all conversion parameters, users who want to convert videos to other formats, and those who want to merge files.

Since there are virtually no options to change output parameters, for instance by lowering the output resolution, it is unsuitable for anything other converting videos to mp4 quickly.

If you need a program that is giving you more options, try Freemake Video Converter or Super Simple Converter instead.

Now You: Which video converter are you using predominantly, and why?

    Why not make use of the mplayer.conf?

    Huh, I have never even seen this “font cache” pane; videos play at once for me, using VLC & XP SP3.

    1. Martin said on August 1, 2010 at 3:39 pm

      Mike, in theory this should have only been displayed once to you, at the very first video that you played with VLC. The time this window is displayed depends largely on the number of fonts in your font directory.

        huh, I lucked out for a change?? Amazing!!
        Apparently VLC keeps this info through version updates, but I didn’t see this message after a fresh OS install about 8 weeks ago, & a new VLC.

      Great tip, thanks a lot Kishore.

    @Kishore, I’ll try your tips, but does this mean it will no longer show subtitles either?
    I do use subtitles, but the fontcache dialog box pops up (almost) everytime I play a file.

    Could this be related to the fonts I have installed? Or if I add/remove fonts to my system?

    I’ll try to do a fresh install also, if your tips does no work. I’ll post back here later…

    @ Javier, The trick i posted will show up subtitles too. If not,Dont worry, VLC is currently sorting out this issue and the next version will be out soon.

    Try running LC with administrator privileges. That seemed to fix it for me

    I am using SMplayer 0.8.6 (64-bit) (Portable Edition) on Windows 7 x64. Even with the -nofontconfig parameter in place SMplayer still scans the fonts. Also, I have enabled normal subtitles and it is still scanning fonts before playing a video. Also, it does this every time the player opens a video after a system restart (only the fist video played).

    Does that mean that only instrumental versions of songs will be available for non-paying users?
