Export trimmed MP4 video

It's a good idea to preview your MP4 video before saving to computer. When you're ready, go to Export menu on top, and select where you want to share your video. Here choose Creating Video. A window will appear, in which you can choose MP4 from the Format dropdown list. Change these settings if necessary. For example, lower the resolution will reduce MP4 file size apparently. In this window, you can also transform trimmed MP4 video to device-compatible format, or directly upload to YouTube. All popular devices are supported, including iPhone/iPad/iPod, PSP, Zune, Creative Video Player, etc.

Besides video trimming, Filmora Video Editor also provides you with other video editing features like splitter, merger, adding special effects, applying transitions between clips, etc. The transition effect is especially useful to merge the two MP4 video clips.
