Using a config file on the microSD card, create a config.txt file with:
[VIDEO]
bitrate=25000000
resolution=720p
hdr=on
A higher bitrate (25 Mbps) at 720p preserves details better than a choked 1080p stream at 15 Mbps.
Using a configuration file (if supported), set the bitrate to between 8-12 Mbps. The April D1 handles 10 Mbps perfectly for 720p. Higher bitrates cause buffer overflow; lower bitrates cause blockiness. cuiogeo april d1 720p better
Comparative analysis against reference 720p encodes revealed three issues:
| Artifact Type | Severity | Likely Cause | |---------------|----------|----------------| | Blocking (8×8) | High | Low target bitrate (<1.5 Mbps for H.264) | | Color banding | Medium | 8-bit depth + high quantization in flat areas | | Ghosting | Low | Unoptimized motion estimation (likely fast preset) | Using a config file on the microSD card, create a config
Conclusion: The encode prioritizes file size over fidelity. Improvement requires transcoding or post-processing.
Older firmware (pre-2023) may hide true 720p 60fps. Update to the latest version from the official Cuiogeo support site (look for "April D1_V2.5_2024.bin"). A higher bitrate (25 Mbps) at 720p preserves
One of the biggest complaints about budget cameras is poor night performance. Because 720p uses fewer pixels per frame, each individual pixel can capture more light. On the Cuiogeo April D1, switching to 720p results in:
For dashcam users driving at night or dawn, the "720p better" claim is backed by real-world footage showing readable license plates at 720p that become smeared blobs at 1080p.
