Codec & Resolution Guide
H.264 vs H.265
A codec is the method used to compress and encode video. Choosing the right codec affects file size, quality, and compatibility.
MP4 Resolution
Resolution is the number of pixels in a video. Higher resolution gives better clarity but increases file size.
| Resolution | Pixel Count | File Size | Best For | Notes |
|---|---|---|---|---|
| 1080p | 1920x1080 | Medium | YouTube, social media | Standard high-quality viewing |
| 720p | 1280x720 | Small | Social sharing | Balanced quality and size |
| 480p | 640x480 | Very Small | Email, low bandwidth | Lower clarity, minimal file size |
Tip: 1080p is recommended for most users for a balance of quality and file size. Lower resolutions are only for low-bandwidth sharing or email attachments. | ||||
