The video won't load in the <video> tag, and played through quicktime I can only get the audio with a gray video. The input is an mp4, it gets spit into an image sequence, filters applied to the images, then recompiled into an mp4: $ffmpeg . ' -i ' . $image_dir . '/audio.mp3 -f image2 -r ' . $framerate . ' -i ' . $image_dir . '/%11d-' . $filter . '.jpg -vcodec libx264 -b ' . $bitrate . ' ' . $video_dir . $filename . '-' . $unique . '-' . $filter .
