“I've got an MP4 video file that's around 1.5GB. I want to trim it down and I don't have a problem using the editing tools to get it to about half its length, but when I go to save the project it ends up being just as large, or larger. How can I just trim it down without increasing its file size?”
There is a general misunderstanding about video trimming that if we cut out some parts from a video, we get a file with a smaller size naturally. But you may experience times that the file gets even larger than the original video after cutting. The main reason is that the video has been re-encoded/transcoded differently. Many video editors will use a different compression method (encoder) or increase the video bit rate, etc. to get the output video quality close to the original, thus increasing the file size. That said, to trim video and reduce the size, you should avoid re-encoding or keep the output settings the same as the input.
In the next part, we provide a reliable video editing program to help you cut video properly without increasing file size. Just read and follow.

Run HD Video Converter Factory Pro on your PC and open the “Converter.” Next, drag your source video into the blank workspace. You can also use the add buttons to import file to the program.
At the bottom of the interface, you can hit the triangle button to set an output path in advance or leave it as default.
Click the scissor icon below the video task to open the Trim window. Next, drag the sliders to select the part you want to keep, then click “Trim” to create “Clip 1.” You can also type in the start time and end time to trim your video more accurately. Repeat this step and you can create multiple clips if you want. When you are done with the trimming, click “OK” to save the changes.
Now, go to the right-side output format list and select an output profile under the “Video” category. It is recommended to keep the same format or choose a format that supports the original video encoder. By default, the software will smart-fit the output settings the same as the input, meaning the same codec, resolution, frame rate, etc. This will help you export video without re-encoding. But you can go to the “Parameter settings” and choose a more advanced video encoder (H265) or lower the bitrate to compress videos to even smaller size.
Finally, click “Run” to finish the whole process. If the hardware acceleration is enabled, it will boost the conversion speed greatly.
