Switch is a media playback, inspection, and conversion tool for media professionals.

Switch 1.0 was designed to export iTunes Store Packages. Switch 2.0 for Mac and Windows evolved into a QC tool for displaying closed captions, GOP structure, interlaced fields, and audio levels for tracks/channels. Switch 3.0 adds new publishing destinations, MXF export options, and an Alternate Media feature for comparing different versions of the same video. It also adds Blackmagic to the existing list of AJA cards and devices for external preview.

Switch supports most professional media formats including UHD and 4K resolutions. Please see the Switch User Guide for a complete list of supported video and audio formats.

Switch Pro supports Avid DNxHD and DNxHR playback, inspection, and pass-through exports.

Switch plays all compressed QuickTime formats not requiring a third party component. Switch also supports Apple ProRes XQ decode on Mac and Windows.

Switch plays uncompressed 4:2:2 10-bit (also known as v210 which is YCbCr 10-bit). For future requests, please contact Desktop Support with the four character code that you need. There are dozens of variations (packed, planar, biplanar, palletized; RGB, RGBA, BGR, BGRA, Y:U:V, Y:V:U, Y:U:V:A; 4:2:0, 4:2:2, 4:4:4, 4:4:4:4, etc.).

Switch plays Windows Media and exports to other formats. A Switch Plus or Pro license is required. Licensed Flip4Mac users can view WMV in free Switch Player.

Audio Video Interleave (AVI) is a container format. Switch can playback AVI wrapped DV (version 1) and MPEG-4 (simple profile).

Switch plays HEVC within an MP4 container. Improved playback of HEVC within an MPEG2 Transport Stream is under development.

Switch can playback the MXF OP-Atom MPEG2 video. Go to the File menu and select Open Secondary Audio File to playback the MXF video and audio files together. Switch also supports JPEG-2000 video codec and J2K support for IMF (Interoperable Master Format) App1 assets.

Switch Plus and Switch Pro display CEA-608 and CEA-708 closed captioning embedded in the video. Go to the View menu and select Enable Closed Captions. Switch also displays DVB subtitles.

Go to the File menu and select Open Secondary Subtitle File to playback Scenarist Closed Caption format (.SCC) and iTunes Timed Text (iTT) subtitles. Switch exports .SCC and .iTT files to the iTunes Store Package along with the metadata. Closed captioning is not embedded in the video. Subrip (.SRT) and .STL subtitles, HTML5 WebVTT (.vtt) and TTML (.xml) files are also supported. Switch 3.1 adds Secondary Subtitle support for opening .MCC, .PAC, and Lambda .CAP (Japanese subtitles).

Ability to sync .SCC captions without having to manually add a caption starting at zero has been implemented in Switch 3.1. The Subtitles Tab now allows the user to enter a value for the desired start time for the secondary subtitle file.

Click the Audio tab and select Locale to view a drop down list of languages to use in metadata. Click the Subtitle tab to select language to use for .SCC captions.

Select Show Timeline under the Switch Pro View menu to see GOP structure. Switch displays I, P, and B frames. I-frames are self-referential. P-frames look backwards. B-frames are bi-directional and look both ways. The timeline has an option to view a data rate curve as well as GOP. Interlacing option determines how to display interlaced video frames on your progressive computer monitor. Select which method to use: Weave Fields, Blend Fields, Split Fields, Field 1, or Field 2. Weave fields is the default. It shows the original frame (2 fields).

Open the primary media file and select Compare Alternate Media under the Switch Pro File menu. Alternate Media Files are listed under the View menu after opening. Select Alternate Media Display to compare the files. Split View displays the selected alternate media file in a split, overlapping window with a sliding bar. Difference View displays the pixel difference between your primary media and the selected alternate media file. The videos are composited into a single black and white signal. Differences between the two videos will appear as highlights on a black backdrop.

The audio meters have decibel bars and can be found under the Window menu. The meters display all tracks, channels and speaker assignments as well as options to mute or solo individual channels and tracks. Switch Pro adds EBU loudness meters. Play the entire file and look at the Integrated “I” column to measure loudness level.

External Preview requires a Switch Pro license and has the option to output VANC data to external monitor via SDI.

In the Switch Container Inspector, click the Gear Icon next to Metadata. Select "Show XML Metadata Content". Safari will display DPP XML metadata in hierarchical format as a document tree.

In addition to asset-only iTunes package export, Switch 3 exports directly to Vimeo, YouTube or Facebook and saves a local copy on your computer.

Switch runs on 64-bit Windows operating systems.

Hardware: Switch for Windows requires a video adapter or graphics card that supports Direct3D feature level 10.1 or higher and a processor that supports the SSSE3 instruction set. A 2.4 Ghz Core 2 Duo or faster and at least 4 GB RAM is recommended.

Software: Switch requires Microsoft .NET Framework 4.0 and Windows Media Foundation.

Windows 7 users need to install Windows 7 Service Pack 1 and the Platform Update. Platform Update was released with Windows 8.

Web link to download Platform Update for Windows 7 and Windows Server 2008:
File name: Windows6.1-KB2670838-x64.msu.

Go to File menu > Preferences > Display. Disable hardware rendering. Relaunch Switch. With hardware rendering enabled in preferences, Switch will try to use the primary display GPU. If the video adapter does not support DirectX, disabling that preference setting will allow Switch to fall back to software rendering.

Switch uses Lanczos scaling on OS X 10.11. This high quality scaling for video playback is enabled by default in Switch preferences. You may need to disable it for smooth UHD full screen 24 fps playback on your monitor. Otherwise, shrink the display to keep up with the frame rate.

There are several models of MacBook Pro with two GPUs. One is integrated (lower performance) and the other is discrete (high performance). The OS is supposed to switch to the discrete card when a power source is connected and use the integrated card when running on battery. However, in some instances the OS may use the integrated card even when plugged in. This can severely affect playback performance in Switch. To disable the integrated card:.

  • Go to System Preferences > Energy Saver.
  • Uncheck the checkbox next to "Automatic graphics switching".
  • Restart the computer.

Please wait until the play bar has finished indexing before playing or scrubbing.

Hold down the Shift key while launching Switch to clear the recent media list. Crash could have occurred while Switch was trying to index the same file that had been open previously, in order to get a thumbnail for the welcome dialog's recent media list.
