6 Methods to Resize Your MP4 Videos as You Wish

Method 1. Change MP4 video encoder without quality loss.

MP4 is a container format for storing data and its encoder greatly affects the size of video. For instance, an MP4 video with H265 encoder has higher compression ratio than an MP4 video with MPEG4 encoder and MP4 (H265) is much smaller than MP4 (MPEG4). So you can reduce MP4 video file by changing the encoder.

Step 2. Choose MP4 format from the Output Format menu.

Then hit “Ok” .

Step 4. Hit “Run” to start your task.

The process in method 3 will not change the video display size. If you want to play an HD MP4 file with widescreen size on iPhone and other mobile devices, you’d better change the aspect ratio from 16:9 to 4:3: Change Aspect Ratio for Better Display Effect.

Methods 4: Change resolution to resize video in MP4

Besides resizing MP4 with the methods above, you can also lower the video resolution. Generally, the more pixels a video has, the sharper the image and the larger the file size will be. So you can change the resolution to resize MP4 but the video quality may be damaged.

Step 1. Import the target files and choose MP4 as output format.

Step 2. Click “Parameters Settings” button and go to the “Video” section on the Settings window. Open the drop-down list next to Resolution and you can see all the ready-made options from 240px160p to 3840px2160p. Choose the desired one and then click “OK”.

Step 3. Specify an output folder and Run.

Or, on the file conversion interface, you can simply drag the slider of Quick Setting to lower video resolution to resize your MP4 file.

Method 5. Reduce bit rate to make MP4 smaller

Video bitrate is one of the most crucial factors affecting video size. So it’s an effective way to resize MP4 files by adjusting bit rate.

Step 1. Drag MP4 videos into HD Video Converter Factory Pro and select MP4 as output format.

Step 2. Go to the “Settings” window and adjust bit rate of the MP4 video. After that, click “Save”.

Step 3. Hit “Run” for the process.

Method 6. Adjust Frame Rate

Another way of reducing MP4 video sizes is to change frame rate. Often, MP4 videos in 24fps and 30fps are enough for vision. And 60fps may lead to audio sync problem. Therefore, we always change frame rate to resize files.

Step 1. Select and import the target videos. After that, choose MP4 as output format.

Step 2. Open the “Settings” window and go to Video section. Choose the desired frame rate from the options. You can also customize frame rate if you want.

Step 3. Choose an output path for the MP4 videos and hit “Run”.
