The files uploaded fine to YouTube as of August 2019. Create a video file from an audio file and add visualizations from audio.Here is a handy list of such formats: all of which are documented under: Here avectorscope is the specific representation type. See also: Combine one image + one audio file to make one video using FFmpegįfmpeg is very featureful, and you can generate several video representations of your audio using with commands of the form: ffmpeg -i audio.mp3 \ It might be possible to reduce the increase in size further by having less keyframes: In our sample data, we had +3 MB on a 3 minute 3 MB MP3 with a 1.1 MB image. The -vcodec libx264 drastically reduces the final video size to be much closer to that of the original MP3: the default video codec appears to be much worse. The -nostdin is required because ffmpeg reads bytes from stdin otherwise, and breaks our read!!! Where the ! forces that size to be used: if the size were 1023x513 we would use: convert image.jpg -resize 1024x512! imag2.jpg Choose mp3 bitrate and tap on Convert button to make the MP3 conversion. Paste the url captured onto the search box above and click on the Search button. If ffmpeg complains that the image size is not a multiple of 2 (required for libx264), you can first find the image size with Imagemagick: identify image.jpgĪnd then round both width and height down to be even, e.g. Go to your video site as YouTube, select your video and copy its url. Obtain some test data: wget -O image.jpg iname '*.mp3' | sort | while IFS="" read -r f do mp3 in the current directory and its subdirectories to mp4: find. Here is a simple find version that converts all.
