# Dissect images and audios from videos Videos are a combination of audios and images and often convey too much information if the fps is too fast or the image/audio quality is not good. When we need a full and comprehensive study on a video, it would be easier to dissect the images and audios from videos and analyze them one by one. **Video quality recovery** This part is not mentioned in the movie but could be a game-changer for the information after dissection. The reason is that the video that was uploaded to the website could be compressed or losing quality. \ detailed procedures on improving the video quality **Convert the audio from video** It can be done by audio converter online or some tools, for example, Adobe. **What kind of information could be used from audio?** In the movie, the most useful information would be: * the background noise (for example, the background music, the sounds from traffic (to tell whether it is in the countryside, the place near the markets), the sounds from people talking, etc), * the language they are using. * A trick is to *tell whether some part of the sounds is pre-recorded or not* (which can be detected by some short notification sounds). **Get full frames images from video.** When fps is large, it is hard to capture detailed information from some single images. In this way, exporting each frame would be more helpful. Also, be aware that you can also enhance your video to *get more frames,* *higher resolution images, better contrast if it is in the night view*. We'll discuss more which images could be obtained from images. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
