Set final MP4 file settings

When you click the "to MP4" output format, there will appear a window where you can set the final MP4 clip parameters. First of all, choose the media quality that you need. If you want to keep everything "as is" without losing video quality after the conversion, select "Same as source" option. Keep in mind, that you have a video file in a non-HD resolution; you can’t select HD or Full HD quality.

Then you need to choose the video codec: MPEG-4 or h.264. Most ready presets go with the second option. However, if you need strictly MPEG-4 codec, you can change the parameters by creating your own MP4 profile. Use the cogwheel button to open the settings & change video resolution, frame rate, sample rate, bitrate, audio codec, and other settings. If necessary, limit the output video file size, and the software will automatically change & suit all the conversion parameters to that value.

In case you want to upload the ready MP4 movies onto your website & share online, mark the option to generate a ready code for your page at the end of the conversion.

One more option for the output video: you may add subtitles downloaded from the Internet. Find the respective option in the main freeware window.

When everything is ready, click the "Convert" button and encode your AVI files to MP4 with the best quality. The conversion process may take some time depending on your PC capacity.

Optional! After your MP4 movies are ready, you can start watching them on a PC or transfer to a portable gadget. We recommend you to play the converted file in a standard media player on your computer. For example, Windows Media Player or VLC are ideal for most multimedia playback.
