That auto-detection of sequences can now be prevented by disabling 'Detect Sequences' operator option (which is enabled by default). This is handy, but also gets in the way when you do want to get single images.

Previously, when selecting more than one image file for Open Image operator (from Image Editor e.g.), Blender would try to detect automatically sequences of animated images, based on numbers in file names.

QuickTime format is disabled since the build options have been fully removed in macOS 10.12.

Audio bitrate & volume are not used when no audio is exported.

Video bit rate options are not used when a constant rate factor is given.

Certain parts of the interface are disabled when not in use:.After all, when this option is chosen FFmpeg is used, which can also output non-MPEG files. Renamed 'MPEG' in the output file format menu with 'FFmpeg video', as this is more accurate.

Your existing startup file may still be set to MPEG2, though, so if you want to use this as a default, right-click on the container, codec, and output quality options, and choose 'Reset to Default Value'. Rather than defaulting to the old MPEG2 tailored for DVD, Blender now defaults to h.264 inside a Matroska (MKV) container. This preset also requires control over the max_b_frames setting. One of the new presets is recommended for reviewing videos, as it allows players to scrub through it easily.

Presets were adjusted for these changes, and new presets added.

Added optional maximum of non-B-frames between B-frames (max_b_frames).

Added FFmpeg speed presets, ranging from 'Very slow' (but best compression) to 'Ultra fast' (but bigger file).

This generally produces the best quality videos in a single pass, at the expense of not knowing the exact bit-rate and file size.

Added Constant Rate Factor (CRF) mode, which allows changing the bit-rate depending on the desired quality and the input.

As a result, codecs were removed from the container list. The 'format' label is no longer used, as this is too ambiguous (both container and codec could be called 'format').

Clearer separation between container and codec.Video encoding settings have been simplified, along with the addition of a Constant Rate Factor (CRF) mode.
