  • Fixed a bug that caused a crash when stepping or playing backwards with certain files.
  • Fixed a bug that caused a crash when opening a file with 6 channels of AAC audio whose speaker labels were not C, L, R, Lb, Rb, LFE.
  • If you enter a start time for a secondary subtitle file that is beyond the last subtitle in the file, we now automatically reset the start time to zero and retry loading the subtitle file. This prevents the situation where a user is unable to open future secondary subtitle files due to a faulty start time retained in the inspector, and unable to change the start time without clearing the application preferences.
  • Fixed a bug where some XAVC 100 Mpbs 4:2:2 59.94 fps TIFO files were mistaken for 29.97 fps.

Improvements

  • Improved subtitle format support including PAC, Lambda CAP, and Ruby Text from WebVTT.
  • Added support for ‘MJPG’ variant of Motion JPEG.
  • Redundant audio tracks are no longer merged when using external preview
  • Added a preference in the Display tab that allows the user to decide whether or not Switch should perform an exhaustive search for captions. It defaults to only checking the first few samples and if no captions are found, the searching stops. This dramatically increases playback performance, particularly over the network, at the cost of not displaying captions in some files where the captions don’t appear until later in the movie. This preference can be changed at any time and does not require reopening the file or relaunching Switch.
  • Trimmed MPEG-2 Transport Stream exports will now periodically repeat the PAT/PMT in order to support some third-party software.
  • Added support for drag and drop of STL subtitle files onto the secondary subtitle section of the inspector.
  • Switch will now tolerate malformed ‘udat’ atoms in MP4 and MOV files.

Improvements

  • Added support for the 'R10g' video four-character-code from AJA as an equivalent format for 'R10k' (AJA 10-Bit RGB).
  • The default frame rate for transcode templates is now the source frame rate when possible.
  • Switch's video preview now uses Lanczos scaling by default in OS X 10.11 and later, to improve the quality of the video when scaled. This can be controlled via the "Use high-quality scaling for video playback" preference.
  • When multiple audio tracks are present, and they contain more than one channel each, Switch will now automatically solo the first track that matches the system language. If none match the system language, then the first track will be soloed. This avoids having multiple languages of audio playing simultaneously by default.
  • Audio meters will now continue to update even when playback is muted. They will be dimmed to reflect that they are muted.
  • Added support for Apple Lossless Audio Codec (ALAC) decoding.
  • The current playback rate will now persist while looping.
  • A "Pause All" menu item is now available when all currently opened videos are playing.
  • Clicking anywhere in a secondary file in the container tab of the inspector now selects that row. Previously, there was an area within that row which, when clicked, would display a popup revealing the path of the file. Since this area took up most of the row, it would frequently get in the way of making a selection. You can still determine the path of the file using the "Show in Finder" or "Copy URL" menu items in the action (gear) button.
  • In an attempt to aid in determining when caption tracks are present in source files, without having to do an exhaustive search of the media that would cause delays, Switch will now search the metadata for each video sample that is displayed, regardless of whether captions are enabled. A caption track will be added in the inspector when caption metadata is found.
  • Switch will now differentiate between C608 and C708 captions in the track list in the inspector. Therefore it is now possible to view caption tracks for 608 and 708 captions in the inspector.
  • Added fit-to-screen constraint sizes for iPhone 5/6/6 Plus, iPad 3/4/Air/Pro, Apple Watch, 2K, UHD, & 4K.
  • Enabled support for raw 8-bit unsigned LPCM in AVI containers.
  • For exports, the default resize mode is now Letterbox/Pillarbox.
  • Improved the mapping of Microsoft Wave Format audio codes to four character codes so that ASF and AVI containers can more frequently identify codecs.
  • Switch will now skip bad packets in ASF containers rather than aborting. This allows for playback of the rest of the movie after the bad packet.
  • Added support for E-AC3 System B (DVB) audio track detection in MPEG-2 Transport Stream and Program Stream containers. Decode support is not available.
  • Switch will now drop out of full screen mode when the application or front most player window becomes inactive.
  • Multiple secondary audio or subtitle files can now be added at once.
  • Improved subtitle/caption menu items for clarity.
  • Added an error to the export summary dialog if you attempt to export video with a non-zero clean aperture to MPEG-2 Program or Transport Streams as these containers don't support it.

Fixes

  • When encountering multiple audio tracks, where some are supported and others are not, Switch previously was unable to play any audio. Now, we skip the unsupported audio tracks and play the supported ones.
  • Fixed a bug that caused corrupted audio playback when an unsupported audio track preceded a supported one.
  • To aid in distinguishing between unsupported audio and audio that contains silence, there are now badges in the audio track table in the inspector that label each track as either available, unsupported, requiring Switch Plus, or requiring Switch Pro.
  • Fixed a bug that prevented playback of DNxHR from within MOV and MP4 containers.
  • Fixed a bug that prevented the use of the x264 bitrate command line parameter for exports.
  • MXF XDCAM files now show commercial name in the format section instead of 'mp2v'.
  • Fixed a crash when trying to open a particular Digital Cinema Package (DCP) JPEG 2000 MXF file.
  • Fixed a problem that prevented the use of EBU STL subtitle files whose Time Code: Start-of-Programme (TCP) value is larger than the Time Code: First In-Cue (TCF), TTI Time Code In (TCI), and TTI Time Code Out (TCO) values.
  • Fixed a bug that caused split captions from WebVTT files to display without a space between some words.
  • Switch now tolerates the incorrect use of the VC-3 picture coding (DNxHR HQX) label in Blackmagic DaVinci Resolve MXF files.
  • Relaxed validation requirements for DFXP caption files to support those created by 3PlayMedia which fail to include the XML declaration node.
  • Switch can now detect Packed RGB 555, Packed RGB 565, and Microsoft RLE in AVI containers, even though these formats are not playable.

General

  • Switch no longer aborts indexing AVI files when unsupported audio is encountered. This allows playback of the other supported media in the file.
  • Fixed several problems, including a crash on Windows, when opening a video while the store window was open.
  • Fixed a crash when attempting to open files with unsupported video.
  • Fixed a crash when opening MP4 or MOV containers with null media headers and no timecode.

  • Fixed a bug that caused any x264 command line parameters entered in custom mode to continue to be used when switching to a preset.
  • Fixed a bug that caused external preview to stop working after switching devices.
  • Fixed a bug in the AIFF container reader that made it assume all audio was PCM. This resulted in compressed audio being tagged as LPCM which resulted in corrupted audio playback in Switch.
  • Updated the AVI container reader to support detecting audio formats that are specified by the subformat field of the WAVEFORMATEXTENSIBLE structure.
  • Enabled identification of AAC and AC-3 in AVI containers.
  • Fixed a bug that caused trimmed exports to always have one additional video frame and caused the "Go" button in the trim section of the inspector to jump to that same one extra frame past the originally intended end of the trim.
  • Fixed a bug that caused the truncated duration of unlicensed exports to be incorrect when exporting to a compressor preset that uses a different timescale than the source.
  • Fixed a hang when attempting to play an H.262 MPEG-2 Program Stream file exported by Switch.
  • Fixed a crash when playing MXF OP-1b.
  • Fixed a bug that caused AAC audio in an MPEG-2 Program Stream to be silent in Switch.
  • Fixed a bug that caused either wasted time, or lost frames, in exports with trimmed leaders and changed frame rates.
  • Fixed a bug that caused transcode exports with trims and reduced frame rates to include superfluous hidden frames, thereby bloating the file size unnecessarily. Transcode exports will no longer include any hidden frames.
  • Fixed display of GOP timeline at high resolutions.
  • Fixed a bug the prevented the export of the current video frame with files whose decompressors generate 'NV12' video.
  • Fixed a bug that caused the magnifying glass button in the export progress dialog to reveal all prior exports, when it should only reveal the one export it is associated with.
  • Fixed a bug that caused the audio sample rate popup in the inspector to be blank if the source used a sample rate that Switch does not support for export. Now, Switch will default to 48kHz.

Fixes and Enhancements

  • iTunes Timed Text (ITT) subtitle files can now be added as secondary subtitle files and will be included in iTunes Store Package exports.
  • The table columns in the inspector are now resizable horizontally.
  • Updated the code signing of Switch to support the new Gatekeeper requirements of OS X 10.9.5 and later.
  • Added support for muting or soloing entire secondary audio files via the Audio menu or via contextual menus in the Audio Meters window.
  • Moved the Container Metadata section to second from the top in the inspector, just below the File section, and above the Secondary Audio and Secondary Subtitle sections.
  • Added support for reporting a problematic file via the Help menu, even if the file is not open.
  • Container, video, and audio metadata field now requires a Switch Pro license for viewing and/or editing.

Bug Fixes

  • Fixed a bug that caused the inspector to enter Export mode whenever the user changed tabs.
  • Fixed a bug that caused a crash on Mavericks when scrubbing to the end of the video and then holding the “J” key to rewind.
  • Fixed a bug that caused a crash when adding more than 32 channels of audio.
  • Fixed a bug that caused the current display scale of the video to be lost when reverting changes, resulting in improper calculations for video edits, when the movie was not displayed at 100%.
  • Fixed a bug that allowed the crop top inset to persist when changing from video transcode to pass-through.
  • Fixed a bug in the remapping of audio input channels to output channels that prevented the preservation of old mappings when the speaker label order of the source did not match the order defined by the program (i.e. Source: L C R Lb Rb LFE, Export: L R C LFE Lb Rb) and the source contained another track with the desired speaker label. Previously, the remapping code would only preserve the mapping if it was in the same order with the same speaker label. Now, if that fails, we also accept the first unused old mapping with the desired speaker label.
  • Fixed a bug with stuttering when pausing and resuming playback.
  • Fixed a bug that occasionally caused the loss of 1 or 2 video frames off the end of a video in transcode exports if the compressor was more than 1 frame behind in delivering its output.
  • Fixed a bug that prevented the purchase of a new serial number if a deactivated serial number was installed.
  • Fixed a bug that prevented the increase and decrease size menu items from working with the shift key down if the video had no audio tracks.
  • Fixed a bug that caused black bars on the top, right, and bottom of non-square-pixel H.264 video decoded by Core Video and shown with the pixel aspect ratio (PAR) disabled, such as when in crop, resize, or clean aperture modes.
  • Fixed three bugs where Switch incorrectly mapped Left Center (Lc) and Right Center (Rc) speaker labels to Left Side (Ls) and Right Side (Rs), respectively.
