Two Ways to Free Decode and Convert H.265 to H.264 Without Quality Loss

High Efficiency Video Coding (HEVC), or H.265, is a video compression standard designed to substantially improve coding efficiency when compared to its precedent, the Advanced Video Coding (AVC), or H.264. HEVC promises a 50% storage reduction as its algorithm uses efficient coding by encoding video at the lowest possible bit rate while maintaining a high image quality level. Majority of PCs, mobile devices, TVs, players and platforms work well with H264, while equivalent hardware or software for decoding HEVC (H.265) is dramatically less common. So many guys want to decode and convert H.265/HEVC to H.264. This article gives you two ways to free decode and convert H.265 to H.264. Read on.
