6 This is a quick followup to the 0.5.8 release to address an issue I want to
7 address immediately. I noticed an extra unconditional colorspace conversion
8 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
9 have enabled the avcolor_space filter on OS X since it works now.
14 The recommended version of FFmpeg for use with this release is 0.6.
15 This is a maintenance release to address some bugs that appeared
16 thus far in the 0.5.x series. Beyond that is a few enhancements:
18 * Added EXIF-based auto-rotation of images to pixbuf and qimage producers.
19 * Improved quality of libswscale-based image conversion and scaling.
20 * Added channelswap and panner audio filters; panner also does balance.
21 * Improve audio waveform and add audiowave video filter.
22 * Enhanced luma filter to work with animated filters such as affine.
23 * Automatically crop 8 bottom lines of 1088 source in a 16:9 project
24 (common in Canon EOS digital cameras).
25 * Added support for inline images in kdenlivetitler.
30 The recommended version of FFmpeg for use with this release is 0.6.
31 This is a maintenance release to address some bugs that appeared
32 this far in the 0.5.x series. Beyond that it a few enhancements:
34 * Added interpolation to the affine transition and filter.
35 * Added multi-track audio encoding to avformat consumer.
36 * Added interlaced field rendering to kdenlivetitle producer.
41 The recommended version of FFmpeg for use with this release is SVN r21322.
42 This is another maintenance release to address some bugs that appeared
43 this far in the 0.5.x series. Beyond that it adds two things that only
44 very specific users will see:
46 * Added C# (ECMA CLR) binding (not enabled by default).
47 * Linsys SDI consumer now configures itself from MLT profile.
52 The recommended version of FFmpeg for use with this release is SVN r21322.
53 This is a minor maintenance release, but it is interesting because it now
54 enables usage of libswscale as the default choice for image scaling,
55 image format conversion, and color space conversion. That gives better
56 quality and performance. In addition, there are some improvements in the
57 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
