I have a software Nuuo. I have also the SDK for build my client. The SDK has all done, but i need to build a client that has some futures not present in the normal client. The developer has to develop a part that in the paying of video should be possible insert some comment and then to export it. This comment must be readable during the video play. (Comment like translation or subtitle when someone is talking). This comment should be not visible on the video but in another section.
