FFmpeg, as a powerful video transcoder, can do this conversion effectively. Next, I will show you how to convert H265 to H264 using FFmpeg. Please read on.

How to Make FFmpeg Convert H265 to H264?

Step 2. Open FFmpeg Command Window

Go to the folder where ffmpeg.exe and H.265 videos are. Then, type cmd in the address bar and press Enter (“Return” on Mac) to open the Command window (Terminal).

Step 3. Let FFmpeg Convert HEVC to H264

Input a command to make FFmpeg convert H265 to H264. Below provide you with several common command lines for different HEVC-to-H264 conversion tasks:

FFmpeg convert MP4 HEVC to MKV H264:
ffmpeg -i input.mp4 -c:v libx264 -crf 18 -vf format=yuv420p -c:a copy output.mkv

Explanation of the command switches:
-i input.mp4 refers to the input video file, -c:v libx264 means using H.264 video codec, -crf 18 is the quality level (bitrate, where 0 is lossless and 51 is the worst), -vf format=yuv420p is the pixel format, -c:a copy will copy the audio data without converting, and output.mkv refers to the resulting video file.
