    # FFMpeg Encoding for online sharing

    # Making h264 mp4 files

    ## Basic no-brainer encoding options

    The -crf 18 option here is very high quality. 20 would be lower quality. The default is actually 23. You can also use fractional amounts e.g. 18.5

    ```
    ffmpeg -i inputfile.avi -pix_fmp yuv420p -c:v libx264 -crf 18 -preset slower -c:a aac -b:a 224k -movflags +faststart output.mp4
    ```

    This is where I usually start, though for 1080p encodes this often creates a file that's way too big so I then reduce the number and find the sweet spot where it's not too large and not too bad-looking.


    ## High quality but with some bitrate limits

    It's possible you may have a target device (like, I dunno, some streaming box) that chokes on high birtates you can set rate limits in addition to keeping your -crf value.

    ```
    ffmpeg -i inputfile.avi -pix_fmp yuv420p -c:v libx264 -crf 18 -maxrate 7M -bufsize 10M -preset slower -c:a aac -b:a 224k -movflags +faststart output.mp4
    ```

    ## Adding Metadata (Title, Author, etc)

    ```
    ffmpeg [settings above except output.mp4] -metadata title="Video Title" -metadata author="Author Name" output.mp4
    ```

    # Webm (using VP9)

    ```
    ffmpeg -i inputfile.avi -c:v libvpx-vp9 -crf 30 -b:v 0 -c:a libopus -b:a 224k output.webm

    *Not usually required* - ffmpeg will often choose the correct option for the codec(s) involed but some encoders can support multiple colorspaces so you sometimes need to be specific. Here are some common ones:

    * `yuv420p` - same as DVD and BLu-ray footage. Common in most compressed streaming media. Use this for encoding for the web
    * `yuv422p` - More chroma samples, used for common intermediate and editing codecs
    * `yuv444p` - 'Lossless' colorspace used for high quality editing codec profiles when using raw footage.
    * `yuv444p10` - as above but using 10bits for the luma channel instead of 8. Better for VFX work - smoother gradients etc.

    ### h264

    The main aspects here are `-crf` which controlls quality (0 being lossless and 22 being the default). `-g` controls GOP length so setting this to 1 makes every frame a keyframe which is ideal for editing.

    ```

    Lossy encoding with every frame a keyframe

    ```
    -c:v libx264 -crf 16 -g 1
    ```

    or, if you don't care about the file size that much and would rather it encode quicker:

    ```
    -c:v libx264 -crf 16 -preset faster -g 1
    ```

    `-sws_flags spline`
    16 is medium quality but higher numbers would be very good quality. The higher the number, the larger the file until you reach lossless.

    ### ProRes

    High Quality 4444 - usually overkill unless doing VFX work

    ```
    -c:v prores_ks -profile:v 4 -pix_fmt yuv444p10
    ```

    High Quality 422 (84 Mbit/s) - use this one

    ```
    -c:v prores_ks -profile:v 3
    ```

    Standard Quality 422 - or this if you are low on space and need something 'good enough'

    ```
    -c:v prores_ks -profile:v 2
    ```

    Proxy Quality - For proxy files only, looks crappy but edits fast and is small

    ```
    -c:v prores_ks -profile:v 0
    ```

    ### DNxHD

    First look up the bitrate you need to set on this table based on the framesize, fps and desired quality level. For each there is a standard and a high quality version. The high quality version is preferred:

    | Project Format | Resolution | Frame Size | Bits | FPS | <bitrate> |
    |----------------|------------|-------------|------|--------|-----------|
    | 1080i / 59.94 | DNxHD 220 | 1920 x 1080 | 8 | 29.97 | 220M |
    | 1080i / 59.94 | DNxHD 145 | 1920 x 1080 | 8 | 29.97 | 145M |
    | 1080i / 50 | DNxHD 185 | 1920 x 1080 | 8 | 25 | 185M |
    | 1080i / 50 | DNxHD 120 | 1920 x 1080 | 8 | 25 | 120M |
    | 1080p / 25 | DNxHD 185 | 1920 x 1080 | 8 | 25 | 185M |
    | 1080p / 25 | DNxHD 120 | 1920 x 1080 | 8 | 25 | 120M |
    | 1080p / 25 | DNxHD 36 | 1920 x 1080 | 8 | 25 | 36M |
    | 1080p / 24 | DNxHD 175 | 1920 x 1080 | 8 | 24 | 175M |
    | 1080p / 24 | DNxHD 115 | 1920 x 1080 | 8 | 24 | 115M |
    | 1080p / 24 | DNxHD 36 | 1920 x 1080 | 8 | 24 | 36M |
    | 1080p / 23.976 | DNxHD 175 | 1920 x 1080 | 8 | 23.976 | 175M |
    | 1080p / 23.976 | DNxHD 115 | 1920 x 1080 | 8 | 23.976 | 115M |
    | 1080p / 23.976 | DNxHD 36 | 1920 x 1080 | 8 | 23.976 | 36M |
    | 1080p / 29.7 | DNxHD 45 | 1920 x 1080 | 8 | 29.97 | 45M |
    | 720p / 59.94 | DNxHD 220 | 1280x720 | 8 | 59.94 | 220M |
    | 720p / 59.94 | DNxHD 145 | 1280x720 | 8 | 59.94 | 145M |
    | 720p / 50 | DNxHD 175 | 1280x720 | 8 | 50 | 175M |
    | 720p / 50 | DNxHD 115 | 1280x720 | 8 | 50 | 115M |
    | 720p / 23.976 | DNxHD 90 | 1280x720 | 8 | 23.976 | 90M |
    | 720p / 23.976 | DNxHD 60 | 1280x720 | 8 | 23.976 | 60M |

    Then add the bitrate to this command (using 1080p 24fps as an example):
    ```
    -c:v dnxhd -b:v 175M
    ```

    ## Breakdown of an FFMpeg Command

    ```
    ffmpeg -i inputfile.mkv
    ```
    ffmpeg -i inputfile1.mkv [Source Settings] [Video Settings] [Audio Settings] [Container Settings] output.ext
    ```

    ## Source Settings

    ### `-pix_fmt` - forces the colorspace you wish to work in

    Not usually required - ffmpeg will often choose the correct option for the codec(s) involed but some encoders can support multiple colorspaces so you sometimes need to be specific. Here are some common ones:

    * `yuv420p` - same as DVD and BLu-ray footage. Common in most compressed streaming media. Use this for encoding for the web
    * `yuv422p` - More chroma samples, used for common intermediate and editing codecs
    * `yuv444p` - 'Lossless' colorspace used for high quality editing codec profiles, especial in VFX work

    ### `Rsizing source video before encoding

    Examples:

    Scale to a particular width, auto-calculate the appropriate height:

    ```
    -vf scale=1280:-1
    ```

    Scale to a particular height, auto-calculate the appropriate width:

    ```
    -vf scale=-1:1080
    ```

    Scale to fit into a 1920x1080 frame and add borders if needed:

    ```
    -filter:v "scale=(sar*iw)*min(1920/(sar*iw)\,1080/ih):ih*min(1920/(sar*iw)\,1080/ih), pad=1920:1080:(1920-(sar*iw)*min(1920/(sar*iw)\,1080/ih))/2:(1080-ih*min(1920/(sar*iw)\,1080/ih))/2"
    ```

    Generic pattern, for any size - just replace XXXX with the width and YYYY with the Y
    ```
    "scale=(sar*iw)*min(XXXX/(sar*iw)\,YYYY/ih):ih*min(XXXX/(sar*iw)\,YYYY/ih), pad=XXXX:YYYY:(XXXX-(sar*iw)*min(XXXX/(sar*iw)\,YYYY/ih))/2:(YYYY-ih*min(XXXX/(sar*iw)\,YYYY/ih))/2"
    ```
