Video support in REAPER

This page will be updated as Reaper v5 progresses.

REAPER supports inserting video items in your project. The item will display the waveform of any audio contained in the video file. 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.

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.

Most of the basic settings for video are handled in Preferences / Media / Video/REX/Misc .

Playback in Reaper 4

Version 4 of Reaper can the video playback systems of the operating system, but for Reaper 4 it is best to rely on the preinstalled FFMPEG libraries and augment those with an installation of the Video Lan Client player, which extends the playback capabilities of Reaper considerably.

The easiest method is to simply install the Video Lan Client player on either Windows or OSX. Be sure to install the 32-bit version of the Video Lan Client (VLC) player for the 32-bit version of Reaper. Install the 64-bit version of VLC for use in the 64-bit version of Reaper. The latest version of VLC is always available here and here.

Tell Reaper to use the VLC player as a video playback method by accessing the Preferences of Reaper and selecting the video page. In the dropdown menu titled Preferred video decoding engine select VLC.

Playback in Reaper 5

Reaper 5 is in beta status at this time ( December 29th 2014 ), but the basic video features are said to be done. Reaper 5 might have some video effects capability, but those will be the subject of a different WIKI entry. Only the basic playback will be covered here.

Windows

FFMpeg libraries in the form of VLC or library binaries, as well as system playback, i.e. functionaly the same as version 4 of Reaper.

Mac OSX

Video playback is provided by the AVFoundation libraries that come preinstalled in all OSX systems starting with v10.7 (Lion). This system library is a lot more efficient than the FFMPEG libraries are, plus the user gains playback of formats like Quicktime ProRes. 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.

Playback method per video format (Reaper 5 only)

Reaper 5 supports a selectable playback method per format. The user can choose a default playback method and provide overrides for specific formats.

At the time of writing (29.12.2014) this is handled via a line of text entered in a box on the Video/REX/Misc page of the preferences.

Default in Reaper v5.0pre1 for Windows is:

libav vlc qt:mov,qt,m4v,mp4 dshow:!mov qt

libav, vlc, qt and dshow are decoding methods. The first one is used before the second and so on.

Decoding overrides for specific formats are used like so :

method:extension-of-video,another-extension,...

Example: vlc:webm (WEBM files are decoded with VLC)

Methods can also be excluded from decoding a specific format like so :

method:!extension-of-video

Example: vlc:!mov (excludes VLC from being used to decode Quicktime files)

Rendering video (Reaper 4)

Starting with v3.52, REAPER supports loading and rendering into AVI and MKV (Matroska) files. The supported codecs are DV, FFV1 (lossless) and Huffyuv (lossless).

If the full FFmpeg libraries are installed, a lot more video rendering formats will be available. The ones included with Reaper only provide encoding and decoding of the free formats mentioned above.

Note that when rendering video using the DV codec format, the video width and height have to be of a suppported DV profile. The 2 most common DV profiles are DV PAL (720x576@25fps) and DV NTSC (720x480@29.97fps).

Reaper 64-bit version, Windows(x64 only), recommended FFMPEG library :

https://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-3.0.1-win64-shared.7z

Unpack the file with 7-zip, Winrar or similar.

There are a bunch of files that have the DLL extension in the directory ffmpeg-3.0.1-win64-shared\bin\. Copy those files to Your-Reaper-Resource-Direcory\UserPlugins\.

You'll need to first tell Reaper to use the FFMPEG libraries you just installed in the Video/REX/Misc page of the preferences, and then restart Reaper for the change to take effect.

To check whether the installation works, place a video on to the timeline and check the Source Properties of the video item (default shortcut CTRL+F2). If the FFMPEG libraries are being used to decode the video, those libaries will show up in the descriptions of the source properties, telling you what is being used for decoding.

Reaper 32-bit version, Windows, recommended FFMPEG library :

https://ffmpeg.zeranoe.com/builds/win32/shared/ffmpeg-3.0.1-win32-shared.7z

There are a bunch of files that have the DLL extension in the directory ffmpeg-3.0.1-win32-shared\bin\. Copy those files to Your-Reaper-Resource-Direcory\UserPlugins\.

You'll need to first tell Reaper to use the FFMPEG libraries you just installed in the Video/REX/Misc page of the preferences, and then restart Reaper for the change to take effect.

Reaper , OSX, recommended FFMPEG library :

Unknown at this time. It is recommended you try the 5.0 pre-release instead, as it lets you decode and encode video much more efficiently with the OSX-onboard AVFoundation libaries.

Rendering video (Reaper 5)

Windows

The same method that is used for Reaper 4 is used for Reaper 5 at the time of writing.

OSX

Reaper 5 uses the AVFoundation libraries built in to OSX 10.7 and higher by default to decode and encode video. This is significantly more efficient for most necessary formats. If you wish to encode WEBM videos however, you'll need to aquire a compiled version of the FFMPEG library once again.

Recommended formats for post production

Quicktime container, using the PhotoJPEG codec at 40-75% quality

This format can easily be produced with the free application MPEG Streamclip, free and available for both OSX and Windows. Windows users should download the 1.2.1b6 beta.

OSX users can probably use ProRes as well, since the AVFoundation libraries support that format, but this is not yet tested.

Reaper 5 advantages and differences for video

Note that these features may change to a small degree, but these features are part of Reaper 5.0 with a high degree of certainty, and have been tested to work at least on Windows at the time of writing.

• Reaper 5 handles the frame rates setting of the project a little differently than Reaper 4 does. The project settings now determine the video output frame rate, so set that to what you need. Video now has its own page in the project settings.

• The timeruler has been fixed to handle 29.97 dropframe video accurately. The timeruler now displays sensible values that are more useful to the user. Most of those fixes will likely be ported back to Reaper 4.

• OSX users can now use the AVFoundation libraries built in to OSX 10.7 and higher, which are more efficient and give the user a good batch of encoding features as well.

• The video window can be docked now.

Tutorials for Reaper 4
