Switch 4 Pro v4.0

Switch is a media playback, inspection and conversion tool for professionals that gives you everything you need to play, inspect and correct your multiformat media in one easy-to-use application.

Play it
Trust Switch for frame-accurate, smooth playback of all your media files, including captions and subtitles.

Check it
Open the Switch inspector to view
in-depth media information in a well-organized display of container, video, audio & subtitle information.

Switch it
Make changes: trim, scale or crop your media; rearrange audio tracks; change speaker assignments, rewrap your media, and more.

Use the iTunes export preset to easily create an asset-only iTunes store package, complete with content and XML file.

High-quality Visual QC
A single tool that plays all your media and displays in-depth information about it ensures more accurate streamlined QC. Switch gives you frame-accurate playback of professional media files, with controls such as single-frame stepping, JKL navigation, and more. You can also view subtitles and captions.

Caption playback and verification
Switch lets you playback embedded CEA-608 & CEA-708 captions, as well SCC, DVB, TTML (iTT and SMPTE-TT captions) and WebVTT subtitle files to verify timing and accuracy. Switch is the only software player with full support for CEA-708 caption decoding, including advanced 708-only features like Unicode character support. See MacCaption / CaptionMaker for caption creation.

Deep file inspection
Backed by trusted Telestream technology and experience, Switch lets you see all the information you’d ever want to see about your media in one intuitive well-organized tool. See metadata (including DPP), bitrate, video essence and codec, audio channels and speaker assignments and much more.

What's New:

Version 4.0:
Note: Switch 4 is a free upgrade for customers with Premium Support; simply download Switch 4 and install. Please check your email for special upgrade instructions, or Contact Desktop Sales if you need assistance. For customers without Premium Support, Switch 4 is a paid upgrade.

  • Added support for playing back files as they are being created (Does not support caption decoding while configured to play back growing files)
  • Added localization for Chinese (Simplified)
  • 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)
  • 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
  • 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
  • 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
  • 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
