FIXES

Customer Issues

  1. Switch 4.5.3
    NEW

    • Added new tab to preferences dialog which allows the user to configure the Dynamic Range Compression for AC-3 and E-AC-3 decoding.

    • Add a new preferences option to control the default export/save location for media or flags files.

      IMPROVEMENTS

      Customer Requested Improvements

      • Improved the default export folder behavior so that the ‘last used’ folder is updated for both media export and the saving of a flags file.

      FIXES

      Customer Issues

    • Fixed a bug that prevented certain Panasonic MOV proxy files from opening and being played back.

    • Fixed an issue that would prevent an export from initiating when trimming some ProRes source files and transcoding to H.264.

    • Fixed a bug that would result in lost frames when exporting from some XDCAM sources to ProRes outputs.

    • Fixed a bug that caused some XDCAM sources to decode with fields out of order resulting in out of order frames in exports, dropped frames during playback, and A/V sync problems during playback.

       

Switch 4.5.2
NEW

  • Added the ability to decode Sony MPEG-4 Simple Studio Profile (SStP).

  • Added the ability to change the color range in edit mode and see the effects in the player window.

    • Added a preference to control whether the default export folder is the same as the source directory or the last directory used.

    IMPROVEMENTS

    Customer Requested Improvements

  • Navigation key commands will now work when the inspector window has the focus unless the selected control accepts the keystrokes.

  • Added stepper controls to crop settings in the inspector.

    General

  • Audio track languages are preserved in MPEG-2 Program Stream containers.

  • Switch will now show an error and automatically revert to the previous color matrix coefficients when there is no conversion path to the user selection in the inspector.

    MPEG-2 Transport Stream with a track containing a number of channels other than 2, 4, 6, or 8. Previously there was no error and the export would fail using this unsupported configuration.

    FIXES

    Customer Issues

  • Fixed a bug that prevented the complete playback of WAV audio files made by Dalet.

  • Added support for pass-through exports of HEVC into the MP4 container.

  • Added support for pass-through exports of DNxHR into an MXF OP-1a container.

  • Added support for decoding and playback of Avid Meridien files.

  • Added the ability to view alpha channels.

  • Added the ability to view safe area overlays for action, titles, and captions.

  • Added the ability to export inspector information as a text or JSON file.

  • Audio tracks and channels can now be muted or soloed directly from the inspector window.

  • Added the ability to adjust synchronization of MCC and TTML (DFXP, iTT, etc...) secondary subtitle files.

  • Added support for pass-through exports of HEVC into an MPEG-2 TS container.

  • Added the ability to display Active Format Description (AFD) codes in the frame metadata overlay.

  • Added support for decoding and playback of FLAC audio as well as from FLAC containers.

  • Added the ability to loop playback within trim in/out points.

  • Switch will now recognize the DCI P3 colorspace.

  • Added display of video bit depth to the inspector.

  • Audio track name metadata from Quicktime MOV files will now be displayed in the inspector.

  • Switch now recognizes Discrete-0, Discrete-1, etc... speaker labels.

  • Added support for decoding and displaying DVB Teletext from MPEG-2 Transport Streams.

    IMPROVEMENTS

  • Expanded the title fields for flags in the inspector.

  • Added additional flag colors to denote good or neutral flags.

  • Switch now remembers when you mute/unmute audio and will reapply that setting to subsequent videos that are opened, including after relaunching the application.

  • Switch now displays the default black background for WebVTT secondary subtitle files.

  • Switch will no longer display roll-out frames from MXF containers.

  • Switch will now peek into SCC files and determine if the timecode format inside is drop or non- drop frame before opening the file. Switch will default the timecode format to the video’s frame rate, and if it is 29.97 or 59.94 it will set it to drop or non-drop frame based on the SCC file data. Instead of defaulting the start time for secondary subtitle files to the last one used, Switch will now default to the timecode of the first frame of video.

  • Added support for the .dfxp file extension as a synonym for the existing TTML extensions (.ttml, .itt, .xml).

  • Added support for language tagging in MXF exports, with limitations. MXF OP-1a will only support language/locale tags for audio, not for video. If you specify only a language (i.e. “de” for German) and not a region (i.e. “de-DE” for German spoken in Germany) Switch will append the current region (i.e. “de-US” for German spoken in the United States).

  • Switch will now preserve subtitles, captions, and/or Teletext when exporting to a codec that supports the metadata container type (DVB, VBI, ATSC A/72 SEI, etc...), or when exporting to MOV which allows for this data to be placed into a caption track.

  • Added the following new speaker labels: Left Wide (Lw), Right Wide (Rw), LFE2, Left Rear Surround (Lrs), Right Rear Surround (Rrs), and Mono (M).

    Windows

    • Added keyboard shortcuts for jumping to the first or last frame via the ‘Home’ and ‘End’ keys.

    FIXES

    Customer Issues

  • Fixed a bug that prevented Switch from remembering the last Teletext page selected, including both when closing a document and when quitting Switch.

  • When exporting flags files, the XML inside will now have a single <Switch> root element in order to improve compatibility with other applications. Both old and new flags files can still be opened by Switch so backwards compatibility is retained.

  • Fixed a bug that caused DFXP captions to be truncated.

  • Fixed a bug that caused chroma displacement of some interlaced AVC content.

  • Fixed a bug that prevented Windows Media Audio 9 from playing in certain files.

  • Fixed a bug that prevented PAC secondary subtitle files from displaying.

  • Fixed a bug that prevented the display of MXF material timecode in some cases.

  • Fixed a bug that prevented the use of some HEVC videos while in split-screen or difference view of the Compare Alternate Media feature.

  • Fixed a bug that caused Switch to use the estimated container duration rather than the actual duration obtained by indexing if the estimate duration was larger. This behavior is still necessary when watching for growing files, but not in other cases.

  • Fixed a bug that caused decoding problems with some Motion JPEG-2000 content.

  • Fixed a bug that caused color quality problems in some ProRes 4:2:2 exports.

  • Fixed a bug that caused 30fps EBU STL subtitle files to play out of sync.

  • Fixed a bug that caused MPEG-1 System files containing MPEG-2 video to display using the wrong default pixel aspect ratio.

  • Fixed a bug that prevented playback of certain GXF files with a mark-in point.

  • Fixed a bug that prevented display of the decibel value for the minimum of the loudness range in the audio meters window.

  • Fixed a bug that caused some ProRes CEA-608 captions to be scrambled on playback.

  • Fixed a crash that occurred when opening some malformed files.

  • Fixed a bug that caused a particular Omneon MOV MPEG file to display as progressive when it was actually interlaced.

  • Fixed a bug that caused H.264 MP4 exports from certain XDCAM MXF files to be missing two frames.

  • Fixed the ‘chan’ atom in MOV/MP4 exports so that it matches the “implicit” AAC speaker labels that Switch supports for 5.1 and 7.1 surround sound.

  • Fixed the sound sample description in MOV files to be version 2 when using more than 2 channels, as required by the Quicktime File Format specification.

    General

  • Fixed a bug that caused field-encoded AVCHD exports to MXF to have frames out of order.

    Windows

  • Fixed a bug that caused some Windows exports to ProRes 4:2:2 HQ to come out as ProRes 4:4:4 XQ.

  • Fixed a bug that caused vertical positioning of WebVTT to be ignored on Windows. This fix will only work on Windows 8 and later.

KNOWN ISSUES

General

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

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

  • No detection of interlaced content is done for Windows Media files.

    Windows

    • Ancillary LTC timecode is not pass when using the KONA 4G with the 4K driver. • Ancillary LTC timecode is not passed while seeking/scrubbing.
