centered-object-video

This places an object (video, image, svg) in the middle of a video. There is a setting that also allows the user to change the background to a color, image, or video.

Example Usage

python blend__video.py \
  --audio-input="media/video"
  --object-input="media/image" \
  --background-color="#fff" \
  --object  -width="600" \
  --aspect-ratio="1280x600" \
  --vid-duration="(30,60)" \
  --opacity=".4" \
  --output-dir="output" \
 &&

Arguments

--audio-input=" "

Can accept either directories (will choose one file at random) or a specific file.

Allowed files: .wav, .mp3, .flac

--object-input=" "

Can accept either directories (will choose one file at random) or specific files.

--object-width=" "

Controls the object width.

--aspect-ratio=" "

Lets you set the size of the outputted video.

Here's a good list of recommended sizing and aspect ratios. https://support.brightcove.com/en/video-cloud/docs/optimal-video-dimensions

--vid-duration=" "

Duration of the outputted video. This will be treated in seconds. You can write a single, definitive number ( eg. 45) or a range that will be randomly selected when run (eg. (30,60)).

--background-color=" "

The background color of the video. Accepts Hex or RGBA values. Setting this value as null makes the background transparent.

--background-video=" "

Allows you to place a secondary video in the background. By default it should fill the screen entirely.

--opacity=" "

Opacity of the centered object.

--output-dir=" "

The directory that the completed thing will output to.

Development Notes

• Not sure how reusable it is, but a previous script I designed uses this pattern: https://github.com/luismqueral/jumpcityrecords
• Each sound thats blended should be panned left right and center, repeating if there are more than three. L and R panning amounts should not be "hard" (panned 100%), let's figure out a way to make them range from 30%-80%.
• The audio library SoX will probably be best for this - http://sox.sourceforge.net/
• Here's a relevant stack overflow i found: https://video.stackexchange.com/questions/12105/add-an-image-in-front-of-video-using-ffmpeg
