Anyway, I converted a HEVC MKV video to H.264 MP4 with ffmpeg for a test. Worse still, after program installed, the errors like 'unrecognized option x265-params', 'fail to set value for crf', 'unable to read files' happen frequently. Many users, especially the green hands feel at a loss even on installing ffmpeg on computer. You can transcode h265 to h264 with ffmpeg indeed, but this HEVC encoder can be a little difficult to work, especially as it has so many options. And FFmpeg, as a free software project that produces libraries and programs for handling multimedia data would come to your mind firstly. To do this, a H265 to H264 converter is in demand. Here are some sample commands to use when encoding videos in h264 (25Mbit bitrate), mpeg2 (50Mbit bitrate) and HAP respecively:įfmpeg.exe -i input.mp4 -c:v libx264 -preset slow -tune fastdecode -profile:v baseline -g 30 -bf 0 -b:v 25M -y output.mp4įfmpeg.exe -i input.mp4 -c:v mpeg2video -g 30 -bf 0 -b:v 50M -minrate 50M -maxrate 50M -bufsize 50M y output.mpgįfmpeg.exe -i input.mp4 -c:v hap -format hap_q -y output.movįiles encoded this way should have excellent performance in WATCHOUT.How to Convert HEVC/H.265 MKV Video to AVC/H.264 MP4 with FFmpeg

We would recommend learning how to use FFMPEG, as it is a very powerful encoding suite allowing you to tweak the preferences to a much higher degree than what you will find built into a lot of applications such as Adobe.įollow this guide to get up and running: While hardware decoding seems to handle B frames well, they incur significant performance penalty in software decoding. Most encoding tools default settings will use B-frames, so you may need to tweak your encoding settings. Use only I frames and P frames - do not use B-frames. There are technical reasons to why WATCHOUT uses software decoding, related to all the functions WATCHOUT provides (which are not available in simple players).įirstly, you might want to look at the frames used in encoding. Other players are likely to use hardware accelerated decoding, while WATCHOUT uses software decoding.
