SwitchTM

Telestream® Switch is an award-winning cross platform media player, inspector, and correction tool for professionals. Switch comes in three versions: Switch Player ($9.99), Switch Plus ($199), and Switch Pro ($499).

Switch Player is a robust multi-format media player with deep inspection capabilities. The media player supports high-quality playback for Windows Media, MXF, GXF, MPS, MTS, MOV, MP4, LXF and more. The inspector displays media properties including audio channels, aspect ratio, bitrate, encoding formats and more. In Switch Player, export is supported in the MP4 container only, otherwise export is watermarked or limited to 30 seconds or half the duration of the media file.

Switch Plus is perfect for video editors and post-production professionals. Plus adds support for embedded caption playback and subtitle files; professional audio meters; export to MP4, QuickTime MOV, MXF (OP-1a and OP-Atom), and MPEG-2 Program Streams and Transport Streams; publish to Vimeo, YouTube and Facebook; as well as additional playback support for HEVC, DNxHD, DNxHR, JPEG-2000, and AC-3 audio.

Switch Pro is designed for Broadcast and Media QC analysis professionals. Pro extends the professional Audio Meters (included in Plus) to include a loudness panel with options to calculate loudness gated (BS1770-3) or un-gated (BS1770-2); as well as deeper inspection of application specific metadata (e.g., AS-11 with DPP metadata). Switch Pro also includes visual representation of the video’s GOP structure; an interlacing option to display fields, and a Compare Alternate Media feature to easily check multiple adaptive bitrate files in ABR workflows for easy comparison of multi-format media. Switch Pro includes all the export support of Switch Plus and adds an iTunes export preset for creating asset-only iTunes store packages.

    *Note: Minimum specifications are the required hardware for playback of standard definition content. Playback of demanding content such as 4K, HEVC, and high frame rate video may require more powerful hardware.

    Switch 4.0 NEW

  • Added support for playing back files as they are being created*.

  • Added localization for Chinese (Simplified).

    *Does not support caption decoding while configured to play back growing files.

    Customer Requested New Features

  • Added Dolby-E detection. Tracks that are determined to be Dolby-E will be silenced to prevent the white noise that results from playing them back as PCM. Decoding of Dolby-E is not yet supported.

  • Added playback statistics as a video overlay, including the number of dropped frames.

  • Added frame metadata display as a video overlay which details what metadata is attached to the current frame, such as timecode or captions.

  • Added ability to flag frames or sequences of frames and add notes to them. This can be displayed in the timeline.

  • You can now specify the timecode format that should be used to interpret SCC files, including frame rate and drop-frame or non-drop-frame.

  • Added support for decoding and playing back Teletext captions (OP-47 and OP-42).

 

IMPROVEMENTS

  • Added experimental support for complex CPL files in IMF packages.

  • All features can now be demoed before purchasing of the licenses that support them.

  • The colorspace settings and display within the inspector now have details that include color primaries, matrix coefficients, and transfer characteristics.

    FIXES

    Customer Issues

  • Switch is now more lenient with MPEG-2 Program Streams that start with invalid data.

  • Switch now supports H.264 video streams that lack Access Unit Delimiters.

  • Fixed a bug that caused LXF MPEG-2 NTSC 4:3 videos to display as widescreen.

  • Fixed a bug that caused line 21 captions to be mapped to line 22 when sent out to a BlackMagic device.

  • Switch is now more lenient when opening DNxHD in MOV with an ARES image description extension that does not end with 80 bytes of reserved data.

  • Fixed a bug that caused interlaced ProRes exports to use the wrong field dominance.

  • Extended the amount of initial delay supported for audio in MPEG-2 TS.

  • Fixed a bug that prevented display of captions from HEVC inside an MPEG-2 TS.

  • Improved the quality of video when seeking. We no longer rely on IDR frame flags, and instead begin decoding at the second previous I-frame.

  • Fixed a bug that prevented opening ASF files created by ffmpeg with an extended stream properties header that has an average time per frame of zero.

  • Fixed a bug that caused frames to display out of order when playing an MXF OP-1a from Adobe Premiere if the body partitions do not start with I-frames.

  • Fixed a bug that prevented opening MP4 files from Vantage whose ‘meta’ atoms are written as a full box with an extra four bytes after the type.

  • Fixed a bug that caused EAC-3 5.1 audio with speaker labels in a different order than L, C, R, Ls, Rs, LFE to be played out to the wrong speakers.

  • Fixed a bug that prevented jumping to a timecode in a ProRes file.

  • Fixed a bug that caused audio/video synchronization loss in H.264 MPEG-2 TS due to audio packets being erroneously lost during the transition between stereo and joint stereo.

    General

  • Fixed horizontal positioning of IMSC captions from MacCaption.

  • Fixed display of IMSC captions in terms of font, size, color, outline, and background.

  • Fixed loss of audio/video synchronization in TIFO files with mark-out frames.

  • Fixed a bug that caused progressive files to come out as interlaced when exporting XDCAM in an MPEG-2 PS or TS container.

  • When doing a frame rate conversion alone in the video processor, if we fail to configure the components due to an inability of the format converter, fallback to BGRA and try again. This prevents some export failures.

  • Switch will now prevent transcode exports of Dolby-E since decoding is not supported. Pass- through is recommended instead.

  • Fixed several bugs that caused distorted audio when playing SMPTE 382M within a Digital Cinema Package.

  • Fixed a bug that caused a crash when exporting an audio-only file.

  • Added TTML to the list of supported extensions for the open secondary subtitle dialog. This allows them to be chosen without needing to change the extension to XML.

    KNOWN ISSUES

    General

  • Decoding of closed captions is not currently supported while Switch is configured to watch for growing files.

  • Frames with long durations make time display appear to stall because it always shows the presentation time of the current frame.

  • ASF files with variable frame rate display incorrect frame rate in the inspector.

  • Detection of interlaced content in Windows Media files is not currently supported.

  • WMV sources exported to H.264 in either MPEG-2 TS or PS containers can results in A/V synchronization problems.

  • Publishing settings are lost when canceling to edit settings to meet requirements.

    Windows

  • Ancillary LTC timecode is not passed when using the KONA 4G card with the 4K driver.

  • Ancillary LTC timecode is not passed while seeking or scrubbing through media.
