I have a marketing consulting firm and help podcasters with social media content creation. I need a website application that can convert .mp3 or .wav audio files from the podcasts into video files with graphic overlays, animated waveforms and embedded titles. Some examples are at [login to view URL] and repurpose.io. It needs to work for short 1-2 minute clips and for long full episode video to be posted on youtube. For short clips, I want to include captioning. See the attached examples.
