For
64bit Windows 10 go to
https://ffmpeg.zeranoe.com/builds/win64/shared/ and scroll down to the bottom of the page and download
ffmpeg-4.1.3-win64-shared.zip -
NOTE it has to be the "
shared" version. You could try a newer shared version e.g. ffmpeg-
4.2.2-win64-shared.zip but I know 4.1.3 works for me.
In Windows Exporler Navigate to
%AppData%\REAPER\UserPlugins
or, from within REAPER, click on the
Options menu and select
Show REAPER resource path in explorer/finder and then navigate to the
UserPlugins folder.
From the downloaded
ffmpeg-4.1.3-win64-shared.zip file, extract
ONLY the
.DLL files (from the
ffmpeg-4.1.3-win64-shared\bin folder) to the
UserPlugins folder.
Restart REAPER.
In the
Render window you should now be able to export H.264 by selecting
Output format:
Video(ffmpeg/libav encoder)
Format:
QT/MOV/MP4
Video coded:
H.264
Specifying the file extension "
.mp4" to the output filename in the
Render window e.g. Filename
.mp4 will force an MPEG-4 container file format rather than a QuickTime ".mov" container.
