The new A119 V3 1440p F1.6 Lens 140FOV Car Camera currently offers the most advanced Image Quality Firmware compared to all other models, especially the massively improved variable Bitrate which increases to over 40 Mb/s on complex scenes. Viofo included a hidden 4K interpolated resolution for early testing of the H.265 HEVC - High Efficiency Video Coding. This stretched 4K resolution tests H.265 HEVC codec compression as a prelude for the "Pro" model. Think of it as a sneak peak at things to come very soon while confirming H.265 works flawlessly.
The A119 V3 > 3840x2160p H.265 HEVC testing resolution is a tease, suggest not using 2160p and select native 2560x1440p using H.265 codec compression for maximum brightness, clarity and detail with optimized Bitrate for reduced MP4 file sizes. My early tests reveal soft sharpness but much smaller file sizes, test footage almost ready. Will compare 1440p H.264 vs H.265 , initial clips favor H.264 compression with larger files.
