Switch is a media playback, inspection, and conversion tool for media professionals. It was originally designed to export iTunes Store Packages and has evolved into a QC tool for displaying closed captioning, GOP structure, interlaced fields, comparison of alternate media by pixels, audio mapping of tracks/channels, and SDI output to an external monitor.

Switch 4 has a Flag feature for QC that lets you choose where to flag a section of your video by setting start and end points. Media with Flags can be exported and re-opened. There are Playback Statistics and Frame Metadata overlays and the Inspector has Color Space settings to display and edit the color primaries, matrix coefficients, and transfer characteristics. A ‘Watch for growing files’ preference setting supports reading and playing of growing media files produced by Telestream’s Live Capture, Vantage, and Pipeline products. Switch 4 also now displays embedded OP-47 Teletext within the application and via SDI.

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

Open the Composition Playlist (CPL) file from the Interoperable Master Format (IMF) package. This will load both the video and audio as primary media. Switch can play simple CPL files (one segment). Support for complex CPL files has been added but is watermarked because the feature is under development.

Export to an iTunes Store Package and the primary media file will contain both audio and video. Secondary audio tracks for other languages are stored in secondary files within the package.

Users can also open the MXF OP-Atom MPEG2 or JPEG-2000 video then go to the File menu and select Open Secondary Audio File to playback the MXF video and audio files together.

Switch supports reading and playing of growing media files produced by Telestream’s Live Capture, Vantage, and Pipeline products.

Enable the “Watch for growing files” checkbox in Switch Preferences in order to preview, edit, monitor, and QC files as they are growing. Indexing behavior has not changed in the Switch Timeline. You’ll see black where the video has not completely downloaded.

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 MXF and ProRes XQ decode on Mac and Windows.

A Switch Player license is needed to play Windows Media and export to MP4. A Switch Plus or Pro license exports to other formats.

Switch plays HEVC within an MP4 container or MPEG2 Transport Stream.

Remote Desktop or Amazon EC2 users must enable an Aero theme with RDP and install an audio device on the remote machine. For details, please see “Configuration for Remote Desktop Protocol” article in the Knowledge Base.

Switch Plus and Switch Pro display CEA-608 and CEA-708 closed captioning embedded in the video as well as Teletext subtitles. Go to the View menu and select Show Subtitles / Closed Captions. CEA-608 selections are CC1-CC4. CEA-708 selections are Service 1–Service 6. Teletext selections are Page 801, 802, 888, 889 or Other. Users can enter a page number between 801-999 (inclusive) when selecting Other. The Secondary Subtitle also appears under this menu and must be selected to view it.

Go to the File menu and select Open Secondary Subtitle File to playback Scenarist Closed Caption format (.SCC) and iTunes Timed Text (iTT) subtitles. Other supported Secondary Subtitle formats are Lambda .CAP (Japanese subtitles) .MCC, .PAC, Subrip (.SRT) and .STL subtitles, HTML5 WebVTT (.vtt) and TTML (.xml) files.

Switch exports .SCC and .iTT files to the iTunes Store Package along with the metadata. Closed captioning is not embedded in the video.

The Flag feature for QC lets you choose where to flag a section of your video by setting start and end points. Flags can be set by time, frame, or timecode. Show Timeline, then go to the Edit menu to ’Add Flag’ and ‘Set Flag Out’. Use the Flags tab in the Inspector to inspect the flags placed in your media and add Titles. Flags can also be edited and color coded yellow, orange or red for errors. The Control menu has an option to inspect all the Flags by Title. Users can go directly to that point or select ‘Next Flag’ and ‘Previous Flag’. Media with Flags can be exported and re-opened. See the Export menu (Flags) and File menu (Open Flags File). File extension is .flags.

Enable ‘Show Playback Statistics’ under the View menu to add an overlay that displays playback frame rate, queue fill percentages, and the number of dropped frames (if any).

Enable ‘Show Frame Metadata’ under the View menu to add an overlay that displays a list of metadata attached to the currently displayed frame, including various types of timecode or captions. Some attached metadata may not be supported by Switch, and therefore will not be displayed.

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 inspector will now display the color primaries, matrix coefficients, and transfer characteristics that make up a colorspace, and in edit mode, allow the user to change each. These properties are included in a detail view accessible via the button to the right of the colorspace. They are hidden by default.

Users can select a known colorspace to automatically populate the color primaries, matrix coefficients, and transfer characteristics. If the user changes any of those settings so that they do not match a known colorspace, the colorspace popup will change to "Unknown". If the user changes any of those settings so that they do match a known colorspace, the colorspace popup will be updated to reflect it.

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.
