# Lower Resolutions (720p and below)

### General concepts

Even though intermediate resolutions such as 936p are feasible, typical V-Nova LCEVC resolutions below 1080p most frequently range from 720p down to 360p. Resolutions lower than 360p are not recommended, even for extremely low bitrates, e.g. <50 kbps. For these bitrates, it is preferable to employ a lower frame rate; for example, 360p at 7-15 fps is recommended. As illustrated above, for resolutions lower than 540p and relatively high-quality points (e.g. proximity to “convex hull”), 1D mode is generally recommended.

In general, for a given bitrate, V-Nova LCEVC \[x264] allows retaining a higher resolution vs. that of the corresponding native codec \[x264]. For example, for mobile use cases and bitrates lower than 800 kbps, the following bitrate ranges are suggested, based on V-Nova LCEVC x264 -preset slow.

| **V-Nova LCEVC resolution** | **Frame rate** | **Bitrate range** |
| --------------------------- | -------------- | ----------------- |
| 720p                        | 25-30          | 500 – 1000 kbps   |
| 544p                        | 25-30          | 350 – 700 kbps    |
| 480p                        | 25-30          | 150 – 500 kbps    |
| 360p                        | 15-25          | 50 – 250 kbps     |

V-Nova LCEVC settings for lower resolutions are typically in line with the recommendations of the previous sections. The quality of V-Nova LCEVC-enhanced encoding at low bitrates depends mostly on determining the best combination of bitrate, resolution and frame rate for the specific content.
