The easiest method is to simply install the Video Lan Client player on either Windows or OSX. The Video Lan Client player can be installed as used too, which extends the playback capabilities of Reaper considerably, but you may have to rely on an older version of VLC to work well enough in Reaper v4.
The user can download FFMPEG binaries that support non-free formats such as MP4 as well.
Playback in Reaper 4 Reaper v4 comes with preinstalled FFMPEG libraries that support only free formats. The user can also use an installed VLC player to play either all or just selected video formats, such as MKV containers, WMV files or WEBM videos. This system library is a lot more efficient than the FFMPEG libraries are.
Mac OSX Video playback is provided by the AVFoundation libraries that come preinstalled in all OSX systems starting with v10.7 (Lion). Windows VLC, recommended! v3.0.8 as of April 19th 2020, FFMpeg(shared binary DLL files)or system playback(same as version Reaper v4). There are some online tutorials available that are just a Youtube search away. The effect plugin "Video processor" provides many different video effects as well. On OSX it may also use the AVFoundation libraries that come with OSX. Playback in Reaper 5 and 6 Reaper 5/6 supports playback of almost any video out there by using the VLC playback engine or the FFMPEG libraries. Video items are handled like any other item, though it is recommended you edit video items only along the frame edges, which means having a SMPTE timeruler active with the frame rate that matches that of the video.īasic settings for video are handled in Preferences / Media / Video/REX/Misc. For longer videos it could take a bit more time than usual to generate that overview, as the entire video file has to be traversed and its, usually compressed, audio decoded. The item will display the waveform of any audio contained in the video file. Video support in REAPER REAPER supports inserting video items in your project.
I am attempting to animate a series of PNG images at 30 frames per second (and add an audio track) with FFmpeg.
