💡 Tip: Remember that MP4 is just a container format and you may need to select a suitable codec to make the video fit for a specific purpose. Simply open the Parameter settings and select the encoder for video and audio separately. If you want to play the video on various devices, keep H264 for video and AAC for audio. If you want to compress the file size, you can use H265/HEVC for the video, which can significantly reduce the video size without noticeable quality loss.

For those who are already familiar with these parameters, you can modify other settings according to your needs. Or you can simply leave them as Smart-Fit to let the program handle the conversion with the common settings according to the format you selected. Don't forget to click OK to save the settings.
