New Release 17.12

Dec 3, 2017

Version 17.12 is now available for DOWNLOAD!

This new version of Shotcut includes improvements for performance, accuracy, and usability:

  • Added icon, progress bar, and time remaining/taken to Jobs panel.
  • Increased maximum resolution to 8192x8192.
  • Indicate if variable frame rate is detected in Properties.
  • Added Convert to Edit-friendly… dialog when variable frame rate or non-seekable file opened.
  • Added Convert to Edit-friendly… to Properties menu for video and audio files.
  • Adding, removing, and adjusting Fade In/Out filters now updates fade controls on the Timeline.
  • Major speed improvements for Timeline rendering, especially when changing zoom level.
  • Stop showing waveforms on muted tracks.
  • Fixed audio crackling on some systems.
  • Fixed accuracy of reading and writing time values, particularly for non-integer frame rates.

Shotcut tries hard to let you edit with many audio and video formats directly without a conversion or import process. However, like most video editors, there are some things that it simply cannot handle such as variable frame rate. Unfortunately many screen, game, and device capture tools create such files. Also, in order to support editing, Shotcut must be able to seek to a frame. This version now tries to detect if a file is variable frame rate or non-seekable and present a dialog to Convert to Edit-friendly format. To keep the process rather simple but still satisfy different users’ needs, it offers 3 pre-defined options. More than likely, all of them will create a file that is larger than the original, which is normal. However, at least you get some choice.

In addition, Shotcut (via MLT & FFmpeg) only does a basic seek test. When it succeeds, it is still not guaranteed to be frame accurate—that depends on many factors: format, codec, parameters of codec, the tool that wrote it, FFmpeg’s code, MLT’s code, versions, etc. There is simply no good way to reliably test for that at the moment. Also, even when seeking works, some files and the way they were encoded seek slowly and may require Settings > Interpolation > Bilinear or better to increase accuracy making it even slower. Therefore, you can choose to convert any audio or video clip to one of the edit-friendly (frame accurate and relatively fast-seeking) formats by using Properties > Menu > Convert to Edit-friendly….

New Release 17.11

Nov 2, 2017

UPDATE: Version 17.11 has been re-released (build 17.11.07) to fix a crash on MP3s with album art - a bug since v17.03.

Version 17.11 is now available for DOWNLOAD!

This new version of Shotcut has quite a few fixes plus the follow set of changes and additions.

  • Changed add-filter menu to be embedded instead of popup.
  • Added Master label to Timeline.
  • Show filters icon on track heads if track is filtered.
  • Prioritize ‘0’ shortcut for Timeline over Playlist.
  • Do not adjust timeline zoom until slider is released.
  • Added warning dialog to Export if file cannot be written (e.g. due to permissions).
  • Added warning dialog to Export if chosen file is in the project.
  • Added warning dialog to Export if the drive is low on space.
  • Added Nepali translation.
  • Added button to Text filter to insert the # symbol.

Shotcut lets you attach filters to many things - not only clips on the Timeline. You can also attach filters to a track or even the entire timeline. In previous blog and forum posts, I have referred to the top left corner block of the timeline as “cornerstone” for lack of another reference. Also, I compared the ability to filter the entire timeline (the result after compositing and mixing) as similar to the “master out” volume slider on a sound mixing console. Therefore, I added the label Master to this selectable block. Furthermore, if you had added a filter to a track (by selecting the track head) or to Master, then you could easily forget about it. Or it could have even occurred by accident! Therefore, Shotcut now shows a Filters icon on a track head if it has filters.

See the screenshot below. The Filters panel is showing the filters applied to Master because it is selected, and there is a Filters icon on the Master track head to indicate that it has filters.

New Release 17.10

Oct 2, 2017

Version 17.10 is now available for DOWNLOAD!

  • Fixed multi-threaded decoding with FFmpeg v3.2.
  • Added 1080p 59.94 and 60 fps video modes.
  • Added support for NVENC to Export panel.

After upgrading FFmpeg to v3.2 in the previous release, we discovered a performance regression because multi-threaded was not working. That is fixed now.

One thing that came with the FFmpeg upgrade is NVENC, which is NVIDIA’s hardware-based H.264 and HEVC encoding for Linux and Windows. The quality is not as good as x264 and x265, but it might be faster for previewing an export or capture or just to play around with. To use it, you must have a NVIDIA GPU that supports it. You must choose “h264_nvenc” or “hevc_enc” from the Export > Video > Codec drop-down list - NOT the Format list. There are not presets provided. You can use the Export defaults or one of the H.264 or HEVC presets and change the codec. Just because it is listed does not mean it will work. The codec is listed without doing any capability test. If you right-click the Export job and choose View Log, then it may show some errors if it is not working. HEVC does not support B frames on most (all?) current devices and drivers. This version of Shotcut makes the Export > Codec rate control fields supply the correct options for NVENC.

New Release 17.09

Sep 4, 2017

Version 17.09 is now available for DOWNLOAD!

While this version contains the usual round-up of fixes and translation updates, it also contains some technology updates:

  • Renewed the code signing certificate for the Windows installer and executable.
  • Updated SDL to v2.0
  • Updated FFmpeg to v3.2
  • Updated x264, x265, and vp8/9 to the latest stable versions.

In addition, primarily for school/institution installations, we added the ability to turn off the welcome message that suggests to check for an upgrade. This works by either running the shotcut executable with the --noupgrade command line option. Or, one can add the option “noupgrade” to the config file or registry, under the General section with the value “true”. This option also hides the Help > Upgrade… menu item.

New Release 17.08

Aug 1, 2017

Version 17.08 is now available for DOWNLOAD!

This version fixes some bugs and tweaks a few things as well:

  • Increased maximum Timeline zoom level.
  • Increased Speed field precision to 3 decimal places.
  • Increased maximum value for Speed field to 200x.
  • Added Norwegian Bokmål translation.
