Version 18.03 is now available for DOWNLOAD!
UPDATE: version 18.03 has been reissued (18.03.06) to address a couple of new bugs introduced: a crash loading SVG images, and broken renaming tracks. As a bonus, the Mosaic video filter has been added.
Here are the highlights of this release:
Version 18.01 is now available for DOWNLOAD!
Here are the main fixes and enhancements in this new version:
The following is a screenshot showing the new Mask filter with a diamond shape. This filter only writes into the alpha channel of the video, which is the transparency information. Therefore, it only shows results when compositing two video tracks on the Timeline.

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

This new version of Shotcut has quite a few fixes plus the follow set of changes and additions.
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.
Version 17.10 is now available for DOWNLOAD!
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.
