+

+- Update to version 3.5

+  New features:

+  * Real-time VBV for ABR (Average BitRate) encodes in –pass 2

+    using --vbv-live-multi-pass. Improves VBV compliance with no

+    significant impact on coding efficiency.

+  Enhancements to existing features:

+  * Improved hist-based scene cut algorithm: Reduces false

+    positives by leveraging motion and scene transition info.

+  * Support for RADL pictures at IDR scene cuts: Improves coding

+    efficiency with no significant impact on performance.

+  * Bidirectional scene cut aware Frame Quantizer Selection:

+    Saves bits than forward masking with no noticeable perceptual

+    quality difference.

+  API changes:

+  * Additions to x265_param structure to support the newly added

+    features and encoder enhancements.

+  * New x265_param options --min-vbv-fullness and

+    --max-vbv-fullness to control min and max VBV fullness.

+  Bug fixes:

+  * Incorrect VBV lookahead in --analysis-load + --scale-factor.

+  * Encoder hang when VBV is used with slices.

+  * QP spikes in the row-level VBV rate-control when WPP enabled.

+  * Encoder crash in --abr-ladder.

 Release Notes

 *************

+Version 3.5

+===========

+

+Release date - 16th March, 2021.

+

+New feature

+-----------

+1. Real-time VBV for ABR (Average BitRate) encodes in –pass 2 using :option:`--vbv-live-multi-pass`: Improves VBV compliance with no significant impact on coding efficiency.

+

+Enhancements to existing features

+---------------------------------

+1. Improved hist-based scene cut algorithm: Reduces false positives by leveraging motion and scene transition info.

+2. Support for RADL pictures at IDR scene cuts: Improves coding efficiency with no significant impact on performance.

+3. Bidirectional scene cut aware Frame Quantizer Selection: Saves bits than forward masking with no noticeable perceptual quality difference.

+

+API changes

+-----------

+1. Additions to x265_param structure to support the newly added features and encoder enhancements.

+2. New x265_param options :option:`--min-vbv-fullness` and :option:`--max-vbv-fullness` to control min and max VBV fullness.

+

+Bug fixes

+---------

+1. Incorrect VBV lookahead in :option:`--analysis-load` + :option:`--scale-factor`.

+2. Encoder hang when VBV is used with slices.

+3. QP spikes in the row-level VBV rate-control when WPP enabled.

+4. Encoder crash in :option:`--abr-ladder`.

+
