Convert HEVC/h265 mkv video to AVC/h264 mp4 with ffmpeg

My first tutorial to convert h265 to h264 with ffmpeg commandline in windows 7. You need to first install ffmpeg in your system. You can check out my previous videos for same.

W.T.F. 2019 Work fine... thank's a lot.

[MrBlastoise]

I would live it if you also did the reverse. H264 > h265

[karthickn]

it is wow.. but is there a way to reduce time consumption for this conversion?

[chome]

I get: Unrecognized option 'x265-params'
Failed to set value 'crf=25' for option 'x265-params'

Converting my first one now, it's a full length movie. I'll test to see if it will now play after through my Vizio USB port. I can play x264 just by changing .mkv to mp4. The x265 will only have sound but no picture. Wish me luck

[yenomeerf]

you couldn't pause the recording?

[charliebrownau]

Gday can you go the other direction, H264/MP4 to HEVC/MP4

[karlhungus]

I receive the following error.

unable to find suitable output format for 'crf=25' crf=25: Invalid argument

Uh, this is bullshit? 20 minutes of ffmpeg output, WTF? When all you need is the damn command line early on? What am I missing?
