The proxy management feature is not ready, but we worked on a building block
in the form a Replace edit command that is integrated into Reverse and
Convert to Edit-friendly. This will be used to asynchronously integrate proxies
after they have been generated.
Added Properties > Speed > Pitch Compensation for automatic pitch correction for speed changes > 0.1x.
Added a Replace command to Timeline clip menu including blank regions with shortcut R.
Properties > Reverse now automatically replaces a selected clip on the timeline (or in Source player if using that).
Added 15 second handles when using Properties > Reverse on a timeline clip. Handles are extra footage before the in point or after the out point. This makes it easier to adjust edits or add transitions around reversed clips.
Added Properties > Duration > Timeline to show (not editable) the duration of a timeline clip.
Added a Corner Pin video filter (thanks to @sauron in the forum for the initial effort).
Added a Properties > Convert button to make Convert to Edit-friendly in the menu more convenient (kept in the menu for now because a number of support tips reference it).
Properties > Convert now automatically replaces respective clips in Source and Timeline and adds its clip to the Playlist.
Fixed = in Text: Simple filter ignores all text before the sign (broken in v20.02).
Fixed a crash when using some video filters with Preview Scaling and multiple video tracks:
Fixed Offset X and Y parameters of Rotate and Scale filter with Preview Scaling.
Fixed video artifacts when using a video for a custom transition and Export > Parallel processing.
Fixed video artifacts when using the Distort video filter and Export > Parallel processing.
Fixed video artifacts when using the Rotate and Scale or Size and Position filters, multiple video tracks, and Export > Parallel processing.
Fixed missing code-signing entitlements for macOS that caused crashes when using the following (broken in v20.02):
Open Other > Audio/Video Device
HTML-based video filters:
Fixed floating or docking some panels may crash on some Linux systems:
Fixed changing the name of a track in Timeline when leaving the field without pressing Enter.
Fixed switching between Cut and Dissolve in transition properties.
Fixed project not modified when changing transition properties.
Fixed pressing Enter in Filters search may open a playlist item.
Fixed a regression in JACK transport control (broken in v19.12).
Fixed a missing Timeline track Lock button animation when lock prevents something.
Fixed clips can be moved to locked timeline tracks (broken in v19.12).
Fixed treating paths with Windows drive letters as relative on macOS and Linux.
Fixed automatically relinking filters with HTML files (when app location changes or moving projects).
Fixed Undo followed by Redo after a Lift or Remove on a transition saves the transition as INVALID.
Fixed some filters than use external files broken when using network (UNC) paths on Windows:
Mask: From File
Fixed Filters > Copy & Paste does not keep filter in and out points.
Fixed opening with a file from the command line on Linux snap or portable.
Fixed Export can overwrite a source when run from command line.
Fixed Keyframes previous/next buttons not using the parameter track to which they belong but rather the current track.
Fixed opening a playlist clip or a new clip breaks filters on Timeline > Master if it is selected.
Changed Export > Video > Parallel processing to default to OFF but also now it save the state between export jobs and app session.
Added support for FFmpeg sample_fmt option to Export > Other.
Automatically disable parallel processing on add-on bigsh0t (360) video filters.
Stop adding title="Anonymous Submission" to MLT XML.
Increased the priority of background jobs a little on macOS and Linux (still less than normal).
Added 448k to Export > Audio > Bitrate.
Added automatically scroll the Timeline when you double-clock a clip to select-and-seek.
Updated the mouse wheel behavior in Keyframes to match the changes to Timeline in version 20.02.
Added an option to place an icon on the Desktop to the Windows installer.
Add a cursor to the Audio Waveform scope.
Removed Export > Stream as it is not supportable in its current state.
Changed shortcuts C and Ctrl+C to work with the clip under the playhead of the current track if no clip is selected. This makes it behave similar to other editing shortcuts.
Changed the keyboard modifier for skim to Shift+Alt. This prevents Shift (previous modifier) when selecting multiple clips from changing playhead position.
NOTE: On macOS, in order to scroll Timeline or Keyframes horizontally with a mouse wheel (not Magic Mouse or track pad), you must also use one of the following:
Changed the Matrix parameter of the Dither video filter to be a drop-down combo box without keyframes support.
Changed Alpha operation > Write On Clear to Overwrite on some video filters to make them more clear:
Most people’s video preview area only occupies a fraction of their screen.
Meanwhile, the app is struggling to process effects in realtime while editing a
1080p or higher video. So, it makes sense to change the processing resolution
while editing to roughly the same as the preview window. For example, for many
people, the video preview typically only occupies 1/9 of their 1080p screen.
Thus, you can edit at 640x360 instead of 1920x1080 to give the app and computer less
This is now available in the Settings under Preview Scaling. If you
are using a larger or high DPI screen or editing higher resolution, you might
want to edit at a higher resolution, and Shotcut also offers options for 540p
and 720p in addition to 360p for the preview vertical resolution.
Please remember that today there is still a processing cost to scale down the
source video to the preview resolution. So, this is still not a silver-bullet,
magical cure-all for performance issues. This feature will be more beneficial
when low resolution proxies are used, which is planned for version 20.04 in April.
Also, please understand that preview scaling is a step further away from WYSIWYG
and does not provide perfect fidelity and full precision. Some differences are
unavoidable especially where blur, softness, and noise are concerned.
In addition, some filters do not support preview scaling and will process at
full project resolution:
Text: HTML > Blank with Web Animations
Text: HTML > Simple Scroll
Text: HTML > Two Column Scroll
Lastly, a Use preview scaling checkbox has been added to Export > Advanced >
Video. This is intended to provide a faster export for draft review. You
should leave the export resolution set to the project resolution unless your
preset or video codec dictates a resolution.
Audio Pitch Filter
Ever since we made it possible to change the speed of a clip, people have wanted
a way to keep the audio at roughly the same pitch instead of going lower or higher.
Also, sometimes people want to use a pitch effect for comical reasons or to
disguise a voice. We are happy to announce a new Pitch audio filter.
This has a speed compensation parameter so that you can copy the speed value
from Properties into the filter. In the next version, we will directly
integrate a pitch compensation option in the Properties panel. Please
consider that this really only works with decent quality in the 4.0x - 0.25x
Frequently, people ask for more transitions. Well, how about 150+!?
After you create a transition by overlapping clips on the same track, select
the transition and look in Properties > Video. There has always been a
Custom… option where you can upload a gray scale still image, and our
provides a list of resources where to get them. In this version you can now
use a grayscale video clip, which some call a “matte transition.”
Forum user @jonray has put together a nice
of these, also on the Resource page.
Please be aware that these transitions do
not automatically adjust their duration. If you do not make the transition long
enough, it will likely be abrupt at the end. If you make it longer, however,
there is no problem. You can also use these to make multi-track transitions by
adding the Mask: From File video filter to the clip on a higher video track.
Added the ability to rename clips in Properties by clicking into the
header where the name is displayed.
Added a few more export presets:
intermediate/ProRes was changed to ProRes 422
Added Arabic translation.
Fixed dropping multiple files to Playlist in a new project (broken in v19.12.31).
Fixed some broken keyboard shortcuts in the Turkish translation.
Fixed Properties > Speed not working after a project file repair.
Fixed clip selection after Insert Track or Remove Track.
Fixed Playlist > Add Selected to Timeline creates corrupt clips (broken in v19.12.31).
Fixed Settings > Display Method > Software (Mesa) on Windows (broken in v19.12.31).
Fixed creating a Project folder with leading or trailing spaces.
Fixed saving the length property in MLT XML as a time value independent of
Fixed starting Text: Simple video filter with “@” shows “0”.
Fixed seeking previous & next on the first track in Keyframes where
you trim a filter or use simple keyframes.
Fixed an unexpected transition is created when moving a clip rightward
adjacent to the next clip in Timeline (regression in v19.12.16).
Fixed drag-n-drop from Source player to Timeline left player in an
inconsistent state (broken in v19.09.14).
Fixed an inconsistent colorspace conversion when accessing a cached image.
Fixed Playlist > Copy followed by a change in Properties incorrectly
changes the playlist item.
Fixed clicking on the rectangle control may change its size.
Fixed using the LUT (3D) filter with file with extended characters in its
file path on Windows.
Fixed a crash when using a transition on every track at the same time.
Improved the reliability of Timeline > Select None.
Changed Timeline > Master > Properties > Frame rate to show 6 decimal digits.
Reduced the latency of scrubbing (regression in v19.12.31).
Changed the video-overlay rectangle control used in some filters to allow
changing the position by dragging from anywhere inside the rectangle.
To enable this, one must first double-click the center circle to change the mode.
Otherwise, you would be prevented from dragging the clip out of the Source player.
Changed the Filters panel on macOS to prevent floating to avoid a
frequently reported problem of the Filters window appearing blank/black.
Changed Timeline > clip context menu > Detach Audio to not seek afterwards.
Improved mouse wheel and trackpad behavior in Timeline.
Now, you do not need to ensure the mouse pointer is over a clip, speed is
reduced, and zoom keeps focal point in view. The new zoom behavior does not
apply when using the option Center the Playhead in the timeline menu.
Upgraded MLT to version 6.20.0 and WebVfx to version 1.2.0.
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
Fixed the intra-VLC and non-linear-quantizer options in the XDCAM-422 and D10
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.
