The audio quality is not as great as the video quality on the camera. Sony Cyber-shot DSC-H300 Digital Camera does not have an internal input for mics. If you need to improve the sound quality you can use audio recorder and synch audio while editing your videos.

Two common suspects would be a locked memory card or a full memory card.

No remote functions at all. This camera has a USB connection used only for downloading pictures to a computer. No Wi-Fi or Bluetooth.

720p is simply a resolution (indicating the video has a resolution of 1280720), and would have no bearing on you obtaining grainy video, or video with digital noise. Graininess, or digital noise, is typically caused either by recording in low-lighting, using a high ISO setting, or both, and is typically seen in the shadow areas of the frame. The only real ways to reduce digital noise is to use a lower ISO setting and to either shoot in bright lighting or add light to the scene (which is one of the reasons Hollywood and other movie companies use so much lighting gear when shooting movies, both at night and in daytime - lighting is an important part of video recording, controlling dynamic range, contrast, and assisting in reducing digital noise/grain). There are some ways to slightly improve video recordings using post-processing software such as Final Cut Pro and Adobe Premiere Elements, though grain/noise may not be completely eliminated due to its random nature. The best I can recommend before/during shooting would be use the lowest ISO possible for the light levels in your scene, use external lighting to lighten the shadows in your scene, and shoot with reduced contrast. During post-production, you may increase contrast and use the editing tools to attempt to further improve the video and/or attempt to further reduce any grain/noise.

On this model, the memory card slot will be located inside the battery compartment. Now, a card reader will be used to transfer images from the memory card to a computer. It is another options if your computer does not have an SD card slot built in.
