3. Choose Efficient Encoder

MP4 files can be made smaller by selecting more effective video coding. For instance, H.265 (HEVC) and AV1 (AOMedia Video 1) are designed to offer improved video compression performance and achieve higher compression rates.

Any Video Converter also supports these two efficient video encoders: HEVC and AV1, allowing users to effectively compress MP4 file for storing, transmitting, and sharing video content without sacrificing video quality.

4. Lower Video Bitrate

Reducing the video bitrate also reduces the size of the video file. In more technical terms, this means reducing the amount of data transferred or stored per second.

When you finish uploading MP4 videos in Any Video Converter, you can see the current video bitrate. Then you can customize the new video bitrate as required.

5. Reduce Video Frame Rate

To shrink MP4 file size, you can do so by lowering the frame rate of the video, because the higher the frame rate of the video, the more frames per second it contains, and therefore the file size will increase accordingly.

Similarly, you can see the specific frame rate of the uploaded MP4 file in Any Video Converter, and then you can lower the frame rate of the video in the FPS option bar on the right.
