It was found that diffusion-based methods provided the most realistic and engaging results in audio generation, capable of synchronizing video and audio information. The V2A system first encodes the video input into a compressed representation, then the diffusion model iteratively refines audio from random noise. This process is guided by visual input and natural language prompts, generating synchronized and realistic audio closely aligned with the prompts. Finally, the audio output is decoded into audio waveforms and combined with the video data.\u003C/p>\u003Cp style=\"text-align: center;\">\u003Cimg class=\"rich_pages wxw-img js_insertlocalimg\" data-imgfileid=\"100005852\" data-ratio=\"0.562962962962963\" data-s=\"300,640\" data-type=\"png\" data-w=\"1080\" style=\"\" src=\"https://res.cooltool.vip/article_res/assets/17423803359950.1623174016461837.png\">\u003C/p>\u003Ch3 style='margin-top: 30px;margin-bottom: 15px;color: rgba(0, 0, 0, 0.85);;font-family: Optima, \"Microsoft YaHei\", PingFangSC-regular, serif;letter-spacing: normal;text-align: left;text-wrap: wrap;background-color: rgb(255, 255, 255);'>\u003Cspan style=\";font-size: 20px;color: rgb(0, 0, 0);line-height: 1.5em;letter-spacing: 0em;font-weight: bold;display: block;\">\u003Cspan style=\"font-size: 16px;\">The V2A system generates audio waveforms synchronized with the video through video pixel and audio prompt inputs.\u003C/span>\u003Cspan style=\"font-size: 16px;\">First, V2A encodes the video and audio prompt inputs and processes them iteratively through a diffusion model.\u003C/span>\u003Cspan style=\"font-size: 16px;\">Then it generates compressed audio, which is decoded into audio waveforms.\u003C/span>\u003Cspan style=\"font-size: 16px;\">To generate higher-quality audio and increase the ability to guide the model to produce specific sounds, more information was added during training, including AI-generated annotations with detailed sound descriptions and dialogue records.\u003C/span>\u003Cspan style=\"font-size: 16px;\">By training on videos, audio, and additional annotations, our technology learns to associate specific audio events with various visual scenes while responding to the information provided in the annotations or dialogue records.\u003C/span>\u003Cbr>\u003C/span>\u003C/h3>\u003Ch3 style='margin-top: 30px;margin-bottom: 15px;color: rgba(0, 0, 0, 0.85);;font-family: Optima, \"Microsoft YaHei\", PingFangSC-regular, serif;letter-spacing: normal;text-align: left;text-wrap: wrap;background-color: rgb(255, 255, 255);'>\u003Cspan style=\";font-size: 20px;color: rgb(0, 0, 0);line-height: 1.5em;letter-spacing: 0em;font-weight: bold;display: block;\">Remaining challenges\u003C/span>\u003C/h3>\u003Cp style='margin-bottom: 0px;;color: rgb(0, 0, 0);font-size: 16px;line-height: 1.8em;letter-spacing: normal;text-align: left;padding-top: 8px;padding-bottom: 8px;font-family: Optima, \"Microsoft YaHei\", PingFangSC-regular, serif;text-wrap: wrap;background-color: rgb(255, 255, 255);'>Since the quality of the audio output depends on the quality of the video input, artifacts or distortions in the video (parts outside the model's training distribution) may significantly degrade the audio quality.
