From a7e74791221e2ef9b44ee1b3eb9ece37785aa62a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sybren=20A=2E=20St=C3=BCvel?= Date: Wed, 21 Sep 2016 15:01:51 +0200 Subject: FFmpeg interface improvements This patch changes a couple of things in the video output encoding. {F362527} - Clearer separation between container and codec. No more "format", as this is too ambiguous. As a result, codecs were removed from the container list. - Added FFmpeg speed presets, so the user can choosen from the range "Very slow" to "Ultra fast". By default no preset is used. - Added Constant Rate Factor (CRF) mode, which allows changing the bit-rate depending on the desired quality and the input. This generally produces the best quality videos, at the expense of not knowing the exact bit-rate and file size. - Added optional maximum of non-B-frames between B-frames (`max_b_frames`). - Presets were adjusted for these changes, and new presets added. One of the new presets is [recommended](https://trac.ffmpeg.org/wiki/Encode/VFX#H.264) for reviewing videos, as it allows players to scrub through it easily. Might be nice in weeklies. This preset also requires control over the `max_b_frames` setting. GUI-only changes: - Renamed "MPEG" in the output file format menu with "FFmpeg", as this is more accurate. After all, FFmpeg is used when this option is chosen, which can also output non-MPEG files. - Certain parts of the GUI are disabled when not in use: - bit rate options are not used when a constant rate factor is given. - audio bitrate & volume are not used when no audio is exported. Note that I did not touch `BKE_ffmpeg_preset_set()`. There are currently two preset systems for FFmpeg (`BKE_ffmpeg_preset_set()` and the Python preset system). Before we do more work on `BKE_ffmpeg_preset_set()`, I think it's a good idea to determine whether we want to keep it at all. After this patch has been accepted, I'd be happy to go through the code and remove any then-obsolete bits, such as the handling of "XVID" as a container format.
