To convert an 8-bit H.265/HEVC video to 8-bit H.264 while maintaining compatibility with older TVs, you can follow these steps:
Prerequisites
- Install FFmpeg: FFmpeg is a free and open-source software project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. You can download it from the official FFmpeg website.
Steps
-
Open your terminal or command prompt.
-
Navigate to the directory containing your 8-bit H.265 video file.
-
Run the following command to convert the video:
ffmpeg -i input.hevc -c:v libx264 -profile:v baseline -crf 23 -pix_fmt yuv420p output.mp4
Here's what the command does:
ffmpeg: starts the FFmpeg application.-i input.hevc: specifies the input file (your 8-bit H.265 video).-c:v libx264: sets the video codec to H.264 using the libx264 library.-profile:v baseline: sets the H.264 profile to baseline, which is compatible with older TVs.-crf 23: sets the Constant Rate Factor (CRF) to 23, which is a balance between quality and file size. You can adjust this value according to your needs.-pix_fmt yuv420p: sets the pixel format to YUV 4:2:0, which is the standard format for H.264 videos.output.mp4: specifies the output file name and format (MP4).
