-\label{sec:Webm / Vp9 Usage and Example File}
-
-There are some common VP9 rendering options files that support creation of video for YouTube, Dailymotion, and other online video services. \ Webm / VP9 \ is a media file format which is free to use under the BSD license and is open-source; thus there are no licensing issues to be concerned about. \ The Webm container is based on Matroska for video and Opus for audio.
-\medskip
-
-Youtube easy startup steps are documented in the Appendix (\ref{sec:youtube_with_cinelerra}). \ These same steps have been verified to work for creating Dailymotion videos -- however, the created files must be renamed before uploading to change the youtube extension to webm instead for Dailymotion.

-\# 20171114-2203
-\# from https://developers.google.com/media/vp9/settings/vod/
-\# 1280x720 (24, 25 or 30 frames per second)
-\#
-\#
-\# Bitrate (bit rate)
-\#
-
-\# VP9 supports several different bitrate modes:
-\# mode
-\# Constant Quantizer (Q) \ \ Allows you to specify a fixed quantizer value; bitrate will vary
-\# Constrained Quality (CQ) Allows you to set a maximum quality level. Quality may vary within bitrate parameters
-\# Variable Bitrate (VBR) \ \ Balances quality and bitrate over time within constraints on bitrate
-\# Constant Bitrate (CBR) \ \ Attempts to keep the bitrate fairly constant while quality varies
-
-\#
-\# CQ mode is recommended for file-based video (as opposed to live
-\# streaming). The following FFMpeg command-line parameters are used
-\# for CQ mode:
-\#
-\# FFMpeg
-\# -b:v {\textless}arg{\textgreater} \ \ \ \ \ Sets target bitrate (e.g. 500k)
-\# -minrate {\textless}arg{\textgreater} Sets minimum bitrate.
-\# -maxrate {\textless}arg{\textgreater} Sets maximum bitrate.
-\# -crf {\textless}arg{\textgreater} Sets maximum quality level. Valid values are 0-63, lower numbers are higher quality.
-\#
-\# Note: Bitrate is specified in kbps, or kilobits per second. In video
-\# compression a kilobit is generally assumed to be 1000 bits (not
-\# 1024).
-\#
-\# Note: Other codecs in FFMpeg accept the -crf parameter but may
-\# interpret the value differently. If you are using -crf with other
-\# codecs you will likely use different values for VP9.
-
-bitrate=1024k
-
-minrate=512k
-
-maxrate=1485k
-
-crf=32
-\medskip
-
-\# Tiling splits the video into rectangular regions, which allows
-\# multi-threading for encoding and decoding. The number of tiles is
-\# always a power of two. 0=1 tile, 1=2, 2=4, 3=8, 4=16, 5=32.
-tile-columns=2
-\medskip
-
-\# modified from https://trac.ffmpeg.org/wiki/EncodingForStreamingSites
-\# To use a 2 second GOP (Group of Pictures), simply multiply your output
-\# frame rate * 2. For example, if your input is -framerate 30, then use
-\# -g 60.
-g=240
-\medskip
-
-\# number of threads to use during encoding.
-threads=8
-\medskip
-
-\# May be set to good, best, or realtime
-quality=good
-\medskip
-
-\# This parameter has different meanings depending upon whether quality
-\# is set to good or realtime. Speed settings 0-4 apply for VoD in good
-\# and best, with 0 being the highest quality and 4 being the
-\# lowest. Realtime valid values are 5-8; lower numbers mean higher
-\# quality
