Codec Duel: H.264, H.265 (HEVC), and VP9 Decrypted

The codec is the brain of your video. Choosing the wrong one can make your file unplayable or unnecessarily heavy. **H.264 (AVC)**: The king of compatibility. It is supported by 100% of devices produced in the last 15 years. Ideal for general public distribution. **H.265 (HEVC)**: The successor. It offers the same quality as H.264 with 50% less weight. It is the standard for 4K and HDR. PulsConv uses it for its 'Best Quality' presets. **VP9 (Google)**: The open-source alternative. Used by YouTube, it is optimized for web streaming. It avoids patent royalties while offering performance close to H.265. **Variable Bitrate (VBR)**: Our engine uses VBR to allocate more data to action scenes and save space on static shots, guaranteeing perfect fluidity.
