FIXES

Customer Issues

• Resolved a macOS-specific color display regression in Switch 5.3’s player that caused washed-out video playback, restoring accurate color rendering.

NOTE: The ARM version of Switch will not be able to decode Cineform because the open source project has not been ported to ARM.

Any Switch user who needs to be able to play Cineform video on ARM Macs will need to quit Switch, and relaunch it using Rosela in order to view the file.

NEW FEATURES

General

• Switch will run on the Mac ARM Apple silicon and will not require the Rosela Translation Layer
• Add user alert when there is a conflict between container and essence metadata.
• Added support for macOS 14 (Sonoma) and 15 (Sequoia)

IMPROVEMENTS

Customer Requests

• Added support for passing timecode to external device.
• Added support for automatic Teletext page detection.

FIXES

Customer Issues

• Addressed issue where DNX Specification 2.0 DNxHD 36 would not open
• Addressed an issue with CEA 608 and CEA 708 captions not being shown in the Switch Inspector
• Addressed an issue with collecting support information on MacOS. The System Profile support information is now gathered in a file called “SystemProfile.spx” on MacOS systems.
• Addressed an issue with OP47 436M Teletext not being displayed in Switch.
• Disabled sync correction in the MPEG-1 system and MPEG-2 transport stream and program stream container readers. This avoids insertion of black frames to fill gaps, overlaps and discontinuities in the timestamps in the file. Please note that files with timestamp gaps/discontinuities in the video may result in AV sync issues
• Improved external playout via AJA Kona and Blackmagic cards to no longer downscale 4K/2K files to 1080p on Mac.

NOTE: The ARM version of Switch will not be able to decode Cineform because the open source project has not been ported to ARM.

Any Switch user who needs to be able to play Cineform video on ARM Macs will need to quit Switch, and relaunch it using Rosela in order to view the file.

NEW FEATURES

Customer Requests

• Added support for AJA Kona LHi.

General

• Added support for macOS Ventura 13.

IMPROVEMENTS

Customer Requests

• Improved scrubbing performance. If the user is moving the scrubber to within 500ms of video, we will continue trying to seek to B-frames and P-frames. If the user has moved the scrubber more than 500ms away from the previous seek attempt, we will instead seek to the nearest I-frame. The user can also hold down the shift key while scrubbing to force Switch to seek to any frame. This can be helpful if they want precision scrubbing and their machine can handle it.
• Made it easier to passthrough Dolby-E by automatically setting the volume to full for external playout and muting it for desktop playback. This removes the need for the user to change a preference setting for analyzing audio to detect SMPTE 337M.
• Removed embedded web browser for purchasing via web store. This allows customers to buy with PayPal again, and avoids potential security concerns. Activation of Switch serial numbers can now be done by clicking on a hyperlink.
• Improved support for sending selected timecode to external devices.

FIXES

Customer Issues

• Fixed a bug that prevented changes to the starting timecode and format for some secondary subtitle files from taking effect the first time they were changed.
• Fixed a bug that caused halos around the borders between masked objects in videos with alpha channels on Mac.
• Fixed a bug that, on rare occasions, caused some very large files to take a very long time to load.
• Fixed a bug that prevented quadraphonic MOV/MP4 files from opening if they lacked a channel configuration.
• Fixed a bug that caused TTML caption top/bottom placements to be swapped in Hebrew and Arabic languages.
• Fixed a bug that prevented opening of UTF-16 SRT subtitle files.
• Fixed a bug that prevented opening of files that contain AC-3 audio in little-endian byte order.

KNOWN ISSUES

General

• Frames with long durations make the 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.
• In the luma scope on Mac, tent and pluge are missing for files that should show them.

NEW FEATURES & IMPROVEMENTS

• Vector Scopes (Technical Preview)
• Added several video scopes, including a luma scope for plotting histograms of brightness, a vector scope for plotting U-V brightness distribution, and a component parade for plotting RGB brightness distribution. Note that this is the initial implementation of video scopes, which is being considered a technical preview, not a completely finished feature set. Future releases of Switch will add more capability to the video scope features.
• Index Advancement During Seek
• Added the ability to advance the indexer during any seek operation, including flag navigation, chapter navigation, jump to mark in/out, 10 second skip, etc. Use the normal controls but hold down the option (Mac) or alt (Windows) keys. Once you do this, subtitle/caption playback will be disabled, as that requires indexing the entire file. Also, our support for advancing the indexer only exists in MPEG-2 TS and MPEG-2 PS containers. If the indexer cannot advance to the desired point within 30 seconds, the operation will be aborted.
• Other New Features
• Added the ability to play Microsoft ADPCM audio from a WAV file.
• Added the ability to play AMR audio files.
• Added the ability to play HEVC MPEG-2 PS files.

• 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.
• Removed extra menu item from the Subtitle/Closed Caption Source menu when using Teletext.

Mac App Store

• In the Mac App Store version of Switch, when opening a file that references other files, such as QuickTime Reference Movies or IMF XML files, Switch will prompt the user to explicitly give permission to open each of the referenced files in order to satisfy the sandbox security requirements. Users who purchase Switch directly from Telestream will not have to perform these additional steps.

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 reading and playing fragmented MP4 files.

Improvements

• Improved the keyboard commands for skipping forward and backward.
• Reduced the amount of memory used when creating and storing chapter thumbnails.
• Switch now caches thumbnails for the recent media list to avoid redundant processing on launch. Cached thumbnails are updated when the file size or modification date changes.

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.

• 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.

• 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.

• CEA-708 captions inserted into H.264 video in an MP4 file via Vantage may have be displayed at improper positions in Switch on Windows, and may cause problems with the video quality on OS X. Both platforms may exhibit audio/video synchronization issues.
• Rewinding jumps forward before rewinding.

Fixes and Enhancements

• Fixed a bug that caused multi-line CEA-708 captions to only show the first line if the captions contained certain special characters.
• Fixed a bug that caused roll-up CEA-608 captions at the top of the screen to only show a single row, when it was configured to show multiple rows.
• Fixed a bug that prevented the display of CEA-708 captions embedded in AVC A/72 Supplemental Enhancement Information (SEI).
• Fixed a bug in the rendering of CEA-608 captions with mid-row style changes.
• Fixed a bug in the rendering of CEA-708 captions on Windows which prevented them from displaying the colored background.
• Switch will now ensure that blank lines in CEA-708 captions have the same height as non-blank lines to preserve the correct vertical spacing.
• Fixed a bug that prevented Switch from detecting PCM audio in certain WAV files.
• Fixed a bug that caused timecode from MXF files not to be displayed.
• Switch will now warn you before exporting an iTunes Store package, if you have trimmed off any chapters. If you choose to continue, these chapters will now be automatically omitted from the package. In addition, all chapters’ starting timecodes will now be automatically adjusted during export to account for trimming.
• Fixed a crash when adding an invalid or malformed secondary subtitle file.
• Fixed problems with opening files larger than 4GB, including the failure to open in some cases, as well as the inability to get creation and modification dates.
• Fixed the command key equivalent for muting audio to avoid conflicts with the operating system’s command key equivalent for viewing all windows in the current application. (Mac only)
• Fixed problems when exporting to a path that contains multi-byte unicode characters. (Windows only)

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.
