How to Create Audio Description for YouTube Videos
The two most common ways to create audio descriptions for YouTube videos are to create descriptions manually or use an audio description vendor.
Going the DIY route will be less expensive, but it is a far more labor- and time-intensive process. On the flip side, you’re guaranteed high-quality, accurate descriptions when you go through a professional audio description vendor like 3Play Media.
Our professional describers watch your video and utilize technology and human editing to create clear, accurate descriptions that follow the DCMP guidelines. The descriptions, using synthesized speech or professional voice actors, are placed using the existing timecodes from your caption file so that they don’t disrupt the viewer from the original audio track.
Outsourcing to 3Play Media
