Keep High Quality for HD, 4K, and 8K Videos
UniConverter helps you convert videos while keeping clear image quality. You can handle HD, 4K, and 8K files with output settings for resolution, bitrate, and codec. Codec means a tool that compresses and decompresses media files.
Adjust MP4 Settings for Your Workflow
You can choose MP4 settings based on your goal. Use H.264 and AAC for broad compatibility, H.265 for smaller file size, or advanced settings for high-resolution videos. This makes your MP4 files easier to play, upload, or edit.

UniConverter also helps you compress MP4 videos, extract audio, convert MP4 to MP3, create GIFs, add subtitles, and enhance video quality. It gives you a simple workflow for common video, audio, and image tasks.
Recommended MP4 Settings for Quality and Compatibility
Not sure which MP4 settings to choose? Start with your goal — better compatibility, a smaller file size, or higher quality for editing and sharing.
H.264 + AAC
Choose H.264 video and AAC audio when you want your MP4 file to play on most devices. This setting works well for phones, browsers, media players, presentations, and social platforms.
H.265 / HEVC
Choose H.265/HEVC when you want a smaller MP4 file with good visual quality. HEVC means High Efficiency Video Coding. It works well for newer devices, but some older players may not support it.
Keep Original Settings
For HD, 4K, or 8K videos, keep the original resolution and frame rate when possible. Use a higher bitrate if you want clearer details. Bitrate means the amount of video data used each second.
| Setting | What It Means | Good Choice for Most Users |
|---|---|---|
| Video codec | Compresses and plays video data | H.264 |
| Audio codec | Compresses and plays audio data | AAC |
| Bitrate | Controls quality and file size | Medium or high |
| Resolution | Sets video size, such as 720p or 1080p | Keep original or 1080p |
| Frame rate | Controls motion smoothness | Keep original |
| Aspect ratio | Sets video shape, such as 16:9 or 9:16 | Match your platform |
