New Version 19.06

Jun 15, 2019

Version 19.06 is now available for DOWNLOAD!

Changes and Improvements

Project Files

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 new capability.

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 read.

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.

Other Changes

  • Changed Export > From to show Source instead of base file name.
  • Changed the default for Settings > Display Method back to DirectX on Windows.
  • Changed maximum duration of Color, Text, and Color Bars clips to 4 hours.
  • 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.

New Features

Blur Filters

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.

Main Toolbar

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)

Additionally:

  • Added Jobs to the main toolbar. Jobs toolbar icon
  • 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.

Crop 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.

  • Crop: Circle
  • Crop: Rectangle

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.

More New Things

  • Added Ripple All button to Timeline toolbar. Ripple all tracks icon
  • Added a vertical Flip video filter.
  • Added Reduce Noise: HQDN3D video filter.
  • Added Noise: Fast video filter.

New Version 19.02: Qt Upgrade and HTTPS

Feb 28, 2019

Version 19.02 is now available for DOWNLOAD!

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 to JavaScript libraries on the Web, which is mostly HTTPS now.

  • Added Offset to the Timer video filter.
  • Added Vertical HD 30 fps and Vertical HD 60 fps video modes.

New Version 18.12: New and Improved Mask Filters

Dec 23, 2018

Version 18.12 is now available for DOWNLOAD!

The new Mask: Apply filter makes it possible to mask filters without using multiple tracks! Use Mask: Simple Shape or Mask: From File to start the filter mask followed the video filters to be masked followed by Mask: Apply to apply the mask to the filters in between. Filters before or after the mask filters affect the entire video frame. One can still use Mask: Simple Shape or the new Mask: From File to affect the alpha channel for multitrack compositing as before.

New Features

  • Added View > Scopes > Video Histogram.
  • Added Preset to some more filters:
    • Audio Gain/Volume
    • Blur
    • Brightness
    • Opacity
  • Added Preset and simple and advanced keyframes to the Balance and Pan audio filters.
  • Added a Levels video filter with simple and advanced keyframes!
  • Added Properties > Color Range for video clips.
  • Replace the Mask video filter with 3 new filters:
    • Mask: Simple Shape
    • Mask: From File
    • Mask: Apply

Screenshot of the New Histogram and Mask and Levels filters

The new Mask: From File is a powerful new video filter offering 3 modes:

  1. wipe transition (stock or custom)
  2. Channel > Brightness from a video or image file (File > Custom…)
  3. Channel > Alpha from a video or image file

Moreover, Threshold can be animated with simple or keyframes, which is especially nice when used with luma-wipe image files (stock or custom). Not only can you wipe on a filter but also you can use this as an alternative way to make a wipe transition using multiple tracks (instead of same track transition).

Fixes

  • Fixed color accuracy of lossless/Ut Video preset and use yuv422p format.
  • Fixed number of digits for seconds in the Timer video filter when using Format > MM:SS.SS.
  • Fixed compositing completely transparent areas of alpha channel darkens output.
  • Fixed some generators (Color Bars, Ising, Lissajous, Plasma) not working correctly in Timeline.
  • Fixed Settings > External Monitor > DeckLink/Intensity can stall when Settings > Realtime is enabled.
  • Fixed making project folder if a parent folder does not exist.
  • Fixed New Project > Start does not save a .mlt file until you open media and save.
  • Fixed launch on some Linux (e.g. gentoo) by including libselinux .
  • Fixed crash when undo Playlist > Remove All.
  • Fixed auto-saved file not removed when save and exit with no changes.
  • Fixed the color accuracy of the Color generator.
  • Fixed numeric locale bug in the Audio Spectrum Visualization and Audio Waveform Visualization filters.
  • Fixed clip reloaded when leaving Properties > Speed with no change.
  • Fixed Settings > External Monitor on Windows screen.
  • Fixed launch crash on Linux with (Csound) csladspa < 6.11.1 installed.

Changes and Improvements

  • Improved color accuracy of internal RGB-to-YUV conversions.
  • Changed Quality to 100% when using the intermediate/ProRes preset.
  • Added 16:9, 9:16, and 1:1 aspect ratios for transition wipes.
  • Moved Properties > Reverse… from the overflow menu to a button.
  • Changed Properties > Reverse… to use project folder if used.
  • When Reverse job completes, automatically open it and add it to the Playlist.
  • Start playback from the beginning if you play when the play head is at the end.
