The main announcement for this release is a major update to an important library
that Shotcut uses for the UI (user interface) called Qt.
There have 6 major releases and two LTS (long term support) releases since the
version we were using. The new version we are using is Qt 5.9.7, which is
LTS (5.9) and is quite stable given the number of revisions (.7). It is a little
faster as well. We did not upgrade to the latest LTS (5.12) in order to retain
compatibility with macOS 10.10 and 10.11, and we want to use the same Qt version
across platforms. (Linux Flatpak is an exception.) With our new Qt builds, we
added support for HTTPS, which extends to our HTML effects based on WebVfx
and QtWebKit. This will let custom HTML titles and effects that you make link
Added Offset to the Timer video filter.
Added Vertical HD 30 fps and Vertical HD 60 fps video modes.
This version makes a big change to the way project files are saved. Now, they
always save numeric values using a period for the decimal point regardless of
your OS locale (region/language) setting. This makes it possible to collaborate
with others that have a different decimal point setting without going through a
(probably incomplete) repair process. This should also help to avoid bugs. This
change applies to new projects only; old projects load and run same as before
including saving. However, be aware that if your locale does not use a period
for the decimal point, then older versions of Shotcut will try to repair a
project created with this version because the older versions do not have this
Timeline and Keyframes Rulers
We changed the Timeline and Keyframes rulers interval to 5 seconds and
show only HH:MM:SS and no frame units. This makes them cleaner and quicker to
Reorganized Some Video Filters
Renamed video filter Circular Frame to Crop: Circle.
Renamed video filter Crop to Crop: Source.
Renamed video filter Text to Text: Simple.
Renamed video filter 3D Text to Text: 3D.
Renamed video filter Overlay HTML to Text: HTML.
Renamed video filter Blur to Blur: Box.
Renamed Reduce Noise video filter to Reduce Noise: Smart Blur.
Changed Export > From to show Source instead of base file name.
Changed the default for Settings > Display Method back to DirectX on
Changed maximum duration of Color, Text, and Color Bars clips to
Increased maximum value of the Timer filter’s Start Delay, Duration, and Offset parameters to 24 hours.
Improved Export Job progress and estimated time remaining.
In the previous versions of Shotcut the Blur video filter could create dark
edges on the image. Therefore, 3 new blur filters were added that do not
have this problem:
Blur: Exponential (fast)
Blur: Low Pass (fast)
Blur: Gaussian (slow)
However, they do not support Keyframes or support blurring in only a horizontal
or vertical direction. So, the existing blur filter was retained but renamed Blur: Box.
The previous version changed the appearance of the toolbar to address a high
density (DPI) issue on Linux. However, that made the icons larger for most
people. Also, some people would simply hide the main toolbar since it took up
so much space. Now, there are two new options in the View menu:
Show Text Under Icons (default on)
Show Small Icons (default off)
Added Jobs to the main toolbar.
Reordered panel buttons on main toolbar to match View menu.
Alpha Channel Support for HTML-based Filters
Shotcut can use HTML technologies for video effects, but previously it was
limited at support the existing image or video’s alpha channel (transparency
mask) and would always overwrite it with its own alpha channel, which often
times was opaque. For example, this prevented maintaining transparency when
using 3D text on a transparent color clip. Now, it supports the alpha channel.
Using this, we have new Crop video filters.
Previous versions of Shotcut’s Crop filter did not behave as some expected
because it removes pixels from the edges of the source and thus changes its
aspect ratio. Still, it can be useful when working with sources with a
higher resolution than the project because it does not require one to crop and
then upscale to remove black bars. Therefore, the existing crop filter was
renamed to Crop: Source, and two new crop filters were added using HTML.
These two new crop filters can use the HTML alpha channel support by changing
the alpha component of their Color parameter. This is very useful when using Crop: Rectangle or Crop: Circle while compositing video tracks.

Version 19.12.31 (aka 19.13) is now available for DOWNLOAD!
Unfortunately, version 19.12.16 introduced a major new bug when moving clips
on the Timeline with Ripple on. This version not only fixes that but also
includes a highly requested feature that was a year end goal: moving
multiple clips on the Timeline! In addition, two more video scopes were
added: RGB Parade and RGB Waveform.
Other Changes and Fixes
Allow reducing track height to very short in Timeline and Keyframes.
Fixed crackly audio playback for some Windows users.
Fixed loading project files made before v19.06 when not using a period for a
Fixed Lift and Ripple Delete on Timeline not reliably removing all
Fixed checking Properties > Image sequence may not update duration in Playlist.
Fixed the intra-VLC and non-linear-quantizer options in the XDCAM-422 and D10
This version continues to rework and refine existing features in the areas of video stabilization, audio normalization, converting and reversing files, external monitoring, and most significantly: the playlist.
Changed Playlist > Open As Clip to simply Open. This action now opens the playlist item directly in the Source player, and all changes made in Source (trim in/out), Properties, Filters, and Keyframes apply to the playlist item immediately without an explicit update.
Added Playlist > Copy that opens a copy of the playlist item in Source just like the old behavior. This is useful if you want to trim out another shot from the same source clip or create a different sub-clip with different filtering.
Changed double-click on a playlist item to Open the clip instead of Copy it.
Added keyboard shortcut Shift+C to Copy a playlist item.
Now, when you drag a clip from Playlist to Timeline the timeline shows an appropriately-size box on a track.
Fixed a performance regression (since v19.06) in the following filters: Chroma Hold, Flip, LUT 3D, Mirror, Noise: Fast, Reduce Noise: Smart Blur.
Fixed reloading the filter UI for Rutt-Etra-Izer, Text: 3D, and Text: HTML resets the filter trimming in Keyframes.
Added support for keyframes to the Lens Correction and Mosaic video filters.
Fixed Swirl when maximum = 0%
Changed the minimum values for Mosaic to 0%.
Removed the scrolling animation from the Blank Web Animations HTML template.
Fixed pasting filters changes the trim and keyframes of the existing filters.
Fixed Crop: Circle and Crop: Rectangle not clearing the canvas resulting in trails in some situations.
Fixed color incorrect when using the LUT 3D filter with some other filters following it.
Fixed reliability of the Stabilize video filter to write its results (.stab) file.
Fixed showing vidstab.trf as a missing file.
Fixed updating Stabilize and Normalize: Two Pass results to clips copied between Source, Playlist, and Timeline.
Added the ability for the Stabilize and Normalize: Two Pass filters’ analysis jobs to update pending export jobs.
Added the option to run pending Stabilize and Normalize: Two Pass filters’ analysis jobs on export. This only works for Stabilize if you are using the project folder feature. Or, if not using the project folder feature, you must click Analyze to assign a results file name, but you can stop the analysis job.
The combination of the above fixes and changes means you can now easily batch convert files while applying image stabilization and audio normalization!
Added support for interlace output to Properties > Reverse and Convert to Edit-friendly including overrides for Scan mode and field order.
Improved detection of interlaced video in some files such as Ut Video in Matroska.
Added Comments to image properties along with a menu button with: Copy Full File Path, Show in Folder, and Set Creation Time…
Add resolution and refresh rates to the screens in Settings > External Monitor to make them easier to differentiate.
Fixed switching between different external screens on the same GPU.
Fixed external screen not showing on correct screen in some arrangements.
Changed the default video quality to 55% for the Default and YouTube presets. This aligns with the x264 default crf of 23 and produces a smaller file that most people desire for upload without significant quality loss.
Added text after Export > Advanced > Codec > Quality to show the generated codec-specific quality level (e.g. crf for x264).
Fixed Stream broken by check for writable file.
Fixed double-click in Recent Projects loading twice.
Fixed disabling meters in the Audio Loudness scope not shrinking space.
Added version metadata to the AppImage for Linux.
Added md5sums.txt and sha256sums.txt to the GitHub releases page.
Added saving Timeline track height to configuration, not only a project file.
Fixed trimming an unselected clip in Timeline does not correctly adjust its filters.
Changed Settings > Interpolation > Nearest Neighbor to no longer relax seek accuracy. Instead, seek accuracy is now relaxed only during trick playback (reverse, rewind, fast forward).
This version makes the Timeline much more flexible. Previously, you could
only move a clip to a blank spot on the timeline, or the move operation would be
rejected and the clip would snap back to its original location. This is no
longer restricted, and you can move anywhere as if you were inserting or
overwriting with a new clip. Of course, you need to be more careful now! Also,
when using drag-n-drop to make a transition, previously you could not have a gap
in the timeline between the two clips. Now, you can drag over a gap and overlap
the clips to make the transition (but still only for neighboring clips on the
same track, by design.) These two improvements were needed to support the
ability to move multiple clips at once. We expect to include that in the first
version of 2020. Meanwhile, there were some important fixes to get out and
changes for people to adjust to.
Added 3 new filters:
Gradient video filter
Scan Lines video filter
Noise Gate audio filter
Added a new color gradient control to the following filters:
Audio Light Visualization
Audio Spectrum Visualization
Audio Waveform Visualization
Added View > Scopes > Video Zoom.

Added Remove Finished to the Jobs menu.
Added Playlist > Update Thumbnails.
Added Update Thumbnails to the timeline video clip menu.
Added keyboard shortcut Shift+Escape to give the player
focus (take focus away from certain widgets).
Added a Two Column Scroll template to the Text: HTML filter (convenient
for film-style credits).
Fixed Scale animation not linear in the Rotate & Scale filter.
Fixed audio crackles in first couple of seconds of export.
Fixed Ctrl+A selects all in Playlist as well as Timeline.
Fixed the size and position of the Text: HTML editor with Settings >
External Monitor enabled.
Fixed drag-n-drop from Playlist to Timeline sometimes reorders the Playlist.
Fixed Color Grading and Contrast creates a weird color after deleting

UPDATE: BlackVue have recently released their DR900S-2CH model, which records at 4K resolution forward, and at 1080p to the rear. The BlackVue DR900S has similar features as the DR750S. It records great video during the day. At night however, the DR750S footage is better.
BlackVue DR750S-2CH Review
In October of 2017, BlackVue released the newest model of their popular dual lens dash cam series. The DR750S-2CH features some impressive improvements over the previous model DR650S-2CH, which has been one of the best-selling high-end dashboard cameras of all time.
Like the DR650S, the DR750S series allows you to live-stream its video feed over the internet, using BlackVue’s cloud service (you’ll need a Wi-Fi hotspot in your car though).
(Don’t confuse the DR750S-2CH with the DR750LW-2CH, which is an entirely different model. The DR750LW is from 2014 and comes with an LCD touch screen, while the DR750S has just been released and doesn’t have a screen at all.)
If you don’t need a rear camera, there’s also a single lens version of this camera available, called DR750S-1CH.
Video quality of the DR750S is very good for the forward facing camera during the day, and good at night time. For the rear camera, video quality is good at day and fair at night.
The most important upgrade compared to the DR650S is that the DR750S-2CH records 1080p both ways. The front camera can even record at 60 frames per second, while the rear camera records at 30fps max. Both the front and the rear camera are now fitted with a 2.1MP Sony Starvis sensor. Video quality is improved, especially for the rear camera. The upgrade from 720p to 1080p makes a major difference.
Note though that while rear video footage has markedly improved, the DR750S’ front video footage seems to be slightly softer, or blurrier, than the DR650S’.
Unlike its predecessor, the DR750S comes with a a proximity sensor that can function either as a mute button for the built-in microphone, or as a lock file button, making this the first BlackVue dash cam to support this feature. You can configure in the camera’s settings which function you want the proximity sensor to perform.
There’s also a physical button on the side. Depending on how long you press this button, it serves to either toggle Wi-Fi, reset the Wi-Fi credentials to factory default, or to format the microSD card. Speaking of Wi-Fi credentials, the default Wi-Fi password is now no longer the same for all the cameras of this model, greatly improving security as many users never bother to change their camera’s password.
With regards to the DR650S-2CH, this model’s video bit rates have been increased from 10 to 12 Mbps for the front camera, and from 5 to 10 Mbps for the rear camera.
The DR750S takes about 23 seconds to boot up, which is 10 seconds faster than the DR650S.
Heat tolerance has also improved, from 60°C (140°F) to 70°C (148°F).
Similarities With Previous Models
The DR750S is equipped with GPS and Wi-Fi. If you have an internet connection in your car, you can watch your car cam’s video footage from anywhere in the world via BlackVue’s cloud service.
This camera will support MicroSD cards up to 128GB in size. For best durability, we recommend getting at least a 64GB card with any dual channel camera. Smaller cards will work, but will result in more writing cycles and thus the card will degrade faster.
A 64GB card will allow for over 6 hours of recording front and rear video, while a 128GB card will let you record for 12 hours before overwriting the oldest footage.
It’s relatively fast to download a 1 minute video clip via Wi-Fi (about 100MB), taking less than 30 seconds typically. Apps for viewing footage and adjusting the camera’s settings are available for Android and iOS smart phones. The apps are well designed and simple to use.
Of course, you can also take out the SD card and watch the footage on your computer. Viewing software is included for Mac and PC.
Like its predecessors, the DR750S supports buffered parking mode to protect your car while you are away. There’s also a time-lapse parking mode, or you can combine the two modes so the camera will record continuously at a low frame rate while parked, and switch to normal recording when an event is detected.
When combined with BlackVue’s Cloud feature, the DR750S can also send a notification to your phone whenever an event is detected while you are away from your car. Without cloud, the camera will speak a voice notification upon your return to the car so you know if, and how many, incidents have been recorded.
For parking mode to work, the dash cam needs to be hard-wired or connected to an external battery pack for power in order to avoid draining your car’s battery.
Alternative Rear Cameras
BlackVue DR750S-2CH IR: Infrared Rear Camera For Use As Taxi/Uber Dash Cam
Optional rear cam with infrared LEDs: Can record the passenger cabin day and night
If you’d like to record the interior of the passenger cabin instead of the road behind you, you’ll need an infrared (IR) camera so you can keep recording at night even when the passenger cabin is dark. This is a great option for Uber or rideshare drivers, vehicle fleet owners, or anyone who wishes to keep memories of fun moments on the road.
A light sensor above the camera lens determines whether ambient lighting is sufficient to record, or whether the camera should go to infrared mode. Two infrared LEDs are situated to the right and left-hand sides of the lens.
BlackVue’s infrared rear camera is called RC100F-IR and fits the DR750S and DR900S models. It is available separately, or in a package together with the front cam.
BlackVue DR750S-2CH Truck: Waterproof Rear Camera To Mount On The Vehicle’s Exterior
BlackVue also have a camera for truckers in their portfolio, or for any vehicle that doesn’t have a rear window. We’ll be presenting the waterproof rear camera here shortly. If you’re curious, you can check out our review of the BlackVue DR650GW-2CH Truck for the time being, which is an older model with a similar system.
Upgrading from DR650S to DR750S
If you already have a DR650S installed and wish to upgrade to the DR750S, you don’t need to go through the hassle of re-doing all the wiring. All the cables are interchangeable between the two models, and the rear camera mount is identical as well. Only the front camera mount would need to be replaced.
You can also order a single channel version of the DR750S. It’s called DR750S-1CH, and the only difference to the -2CH is that it comes without the rear camera and coax cable.
Many features have been added or improved with regards to the predecessor, the most notable being the better rear video quality. BlackVue have also finally included a lock file button option, no doubt a welcome feature for many users.
Overall, the DR750S-2CH is an excellent high-end camera with great features, and one of our favorite dash cams of the year 2018.
BlackVue DR750S-2CH Video Samples
For full original video quality, make sure to watch on full screen and select maximum video resolution (use the cog icon in lower right corner). You may have to rewind the video after changing the resolution.
Day Time Front Video Sample
Day time forward video quality is very good. License plates of nearby cars are easily readable.
Day Time Rear Video Sample
Rear video at day time is good. It is hard to read license plates of overtaking cars though.
Night Time Front Video Sample
Forward video at night is good considering this is a rather dark road. However the license plates of nearby cars are unreadable.
Night Time Rear Video Sample
Night time rear video quality is fair. This clip looks attractive on a brightly lit road, however there is some glare from other cars headlights, and license plate readability is hit-and-miss depending on the angle you catch them.
