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.

Step by Step to Decode and Free Convert HEVC/H265 to H264 on Windows
Step 1: Load H265 Files
Import H265 files via "Add Video" button or just drag and drop H265 files to this top HEVC video converter. Batch conversion is supported.
Step 2: Enable GPU Encode Acceleration.
Click "Tools" > "Options", in the opened "Options" window, click "Acceleration" menu, then check "Enable GPU Encode Acceleration" otpion so that the program will accelerate conversion speed when encoding H.265/HEVC to H.264 codec.
NOTE: You need to make sure your PC configuration supports the GPU acceleration, you can refre to this: Nvidia Cuda Speed Up.
Step 3. Output video with H.264 codec
Click "Format" drop-down bar, you can select "Common Video" > "H.265 Video(*.MP4)" as the output file format, you also can choose H.264 High Profile Video (.*mp4) which can provide the HD video with fast speed.
Tip: You are allowed to adjust video and audio parameters if you are not satisfied with the default settings. Presets like size, bitrate, frame rate, audio channels, etc. can be customized in your own way.
Step 4: Begin the H.264 codec encoding process.
After all settings is completed, hit right-bottom "Convert" button to begin the conversion from H.265/HEVC to H.264 encoding process. When the conversion is completed, you will get a perfect quality H.264 file for smoothly viewing and streaming on different devices.
