How to Edit MP4 Video in Mac/Windows (Windows 8 included)

MP4 is a very common media format that can keep high image and sound quality. Many downloaded movies, streaming music videos, or recorded video clips are with .MP4 file extension.

If you have many such files, chances are that you need to edit MP4 videos. Although various MP4 editors are available on the market, they are a little space-consuming in order to ensure good performance. Here I’d like to share a powerful and efficient MP4 editor that designed for beginners and hobbyists. It’s Wondershare Filmora (originally Wondershare Video Editor). With it, you’re able to trim, rotate, crop, merge MP4 files, as well as personalize your MP4 videos with rich text, filter and transitions. Moreover, after you finish MP4 video editing, you can directly share your creation on YouTube, Facebook, or save to any format you want.

How to Easily Edit MP4 Video:

1. Cut MP4 Video

To cut your MP4 video in to certain parts, drag and drop the video on the Timeline and highlight it. Then place the red Time Indicator to where you want to cut the video, and click the Scissor button above the timeline. After that, move the red marker to the end of the scene, and repeat this again to cut the video into several fragments. If you want to cut off the unwanted parts, right click the video and choose "Delete".

2. Join MP4 Video

To join several MP4 video files into one, you just need to place all the video files on the timeline, adjust the order and hit "Create" to export it.

If you want to make the joined videos look like a really intact movie, just add transitions between clips for smooth change from one to next. To do this, click "Transition" tab on the main screen. Then drag the effect you like to the timeline to apply. If you don't want to choose the transition one by one, let the software choose the transition randomly by right clicking and selecting "Random to All" option.

3. Edit the audio of MP4 Video

Sometimes you may need to adjust the settings of audio. To do it, double click the video on the Timeline. Then a editing panel will pop up. Switch to Audio column and you can easy change the Speed, Volume, Pitch of the audio file or add the Fade in/out effect to it.

Want to change the original audio track of your MP4 video? No problem. Just highlight your MP4 video, right click and choose "Audio Detach". The audio file of your video will immediately be separated and appear on the music timeline. Since it is separated from the video, you can easily delete the audio track or replace it with your own music.

Hi Mak, sorry you can't edit with Filmora.
Yes that is sufficient!
I have an IBM / Lenovo desktop with onboard Intel Q35 chipset graphics. Is this sufficient to run your software?
Is there any way I can edit my existing mp4 video text ?
Hi, Bree, I checked our software can't help to create new audio files from the character's voice. it only support to insert voice/music which has already been created by other ways. I will send to our R&D department for reference. Kind regards.
I have character's voices that I want to use but the stuff I want them to say I don't have. In this program is there a way to use an MP4 of the character's voice to get/create audio of what I want them to say?
Sorry to say the mac version can't export to audio files, but the windows version has this feature. We will try to add this feature for mac in future.
is there an audio format for export on a mac to download the audio so I can run it through audacity to remove some background noise - the auto denoise and enhance doesn't help
While attempting to install from the 960 kb downloaded file, it is again downloading the source .exe. Is it possible to save this large source .exe file from which the installation actually happents and what is the path of this large source file? this is to avoid repeated downloading to save bandwidth. Thank you.
It depends on the size of your video.
