Video Tutorial: Record a Voice Over

Feb 19, 2017

There is a new video tutorial about how to record a voice over from the microphone using the latest version 17.02 of Shotcut.

Regressions, We've Had a Few

Feb 1, 2017

Lately, we have been focused primarily on bug fixes, and sometimes a bug fix introduces a new, often times worse bug, which is called a regression. Due to major regressions in v17.01 all users are strongly encouraged to
UPGRADE TO VERSION 17.02.

  • Fixed drag-n-drop from other than C: drive on Windows.
  • Fixed ‘/’ getting added to front of file paths on Windows.
  • Fixed the MLT XML repair tool not correctly handling decimal point in some configurations.
  • Fixed opening a network stream.
  • Improved support for image sequences.
  • Improved device capture.
  • Added Slovenian translation.

All device capture now occurs in the background. This makes it possible to record voice overs while playing the project. I plan to make a video to show how to do this soon.

New Release 17.01

Jan 2, 2017

This version is just bug fixes plus a Chinese translation for Taiwan was added.

Version 16.12

Dec 3, 2016

Version 16.12 was released today and is available for DOWNLOAD.

  • Added Constrained VBR for the video codec rate control mode to Export.
  • Added Fixed option to video GOP to Export.
  • New audio mixing mode that does not affect levels.
  • Increased usage of floating point for audio processing to improve quality.
  • Added Occitan translation.
  • More fixes for copying filters and LUT (3D) video filter.

More About the New Audio Mixing

The first thing you need to know about the new mixing mode is that it only applies to new projects. You might have already adjusted volume levels in existing projects, and we did not want to affect that.

Versions before 16.10 used a mixing technique that tried to be clever about generally preserving the levels of all sources without clipping, but it was discovered that it may introduce artifacts. So, versions 16.10 and 16.11 switched to a simpler method that adds samples, but it was also averaging them to avoid clipping, which was found to adversely affect levels. So, the new approach in this version is to simply add samples.

As a result, you may experience clipping. Now, as long as there is so-called headroom in the level each of source, this should rarely be a problem because high level samples from each source are rarely correlated. Here is where the Normalize filters are your friends because not only do they bring all sources to the same level, but the default target level includes headroom. In addition to listening for clipping, you can visually monitor it using the Peak Meter and/or Audio Waveform scope in the View menu.

If each source has headroom in its level but you still experience clipping, you can add a Gain/Volume filter to the Timeline - select the cornerstone at the top, left of the Timeline and use the Filters panel. This is like the Master Out gain control on a mixing console. Reduce the gain until you eliminate the clipping. If you find that you need to lower the gain more than you like try adding the Limiter filter.

Version 16.11 - Now a Portable App

Nov 2, 2016

Version 16.11 was released today and is available for DOWNLOAD.

By popular demand, this version includes a new so-called portable app feature. A portable app is one that can be run without having to install and register components into the system. Rather, it is a self-contained folder for the executable and its bundled dependencies. Shotcut has always been portable in this sense regardless of the operating system. Portable apps can be put on a USB stick/drive and run from there. Then, you can use the app from computer-to-computer simply by plugging the USB stick. However, to be truly portable, the app should also use the USB stick to store settings and other app data.

Like most apps, Shotcut has an app data directory wherein it stores its thumbnails/waveforms database, presets, and log file. Normally, it stores settings in a platform-defined manner such as the registry on Windows or a plist file in ~/Library on macOS. Now, you can set the app directory using the command line option “–appdata <directory>” or the Settings > App Data Directory menu. When you do, then settings are instead saved in an INI file in the designated folder. If you use the menu, Shotcut will try to migrate everything from the current location to the new location only if there is not existing Shotcut data in the new location. Otherwise, it simply lets you start using the new directory adopting the settings and data. If you use the command line option, the new menu item is hidden making it possible to integrate the app into an app launcher/updater more seamlessly.

Here are some other changes in this version:

  • Fixed drag-n-drop to Timeline after moving clip to different track.
  • Fixed LUT (3D) filter for languages/regions that use comma for decimal point.
  • Fixed Properties > Speed on macOS for languages/regions that use comma for decimal point.
  • Added Gaelic (Scottish) translation.
