# Video overlay feature limitations Video overlays have the following restrictions: + MediaConvert does not support audio playback or separate captions for video overlays. During a video overlay, any audio or captions from your base input video will continue uninterrupted. + Video overlays are specific to individual video inputs. For example, if your job settings include three video inputs, you can add an individual video overlay to **Input 1**, **Input 2**, and/or **Input 3**. You cannot however add a single video overlay that spans across all three inputs. + You can include up to 99 video overlays in your job settings and up to 99 input clips in each video overlay. + MediaConvert does not support transparency for video overlays. Any alpha channels present in your input will be black in your output. + For consistency in color and formatting in your output video image, we recommend that you specify video overlay files with accurate and complete color metadata.
