    Galaxy S25 Ultra Camera: Virtual Aperture, RAW Editing, AI Upgrades

    Samsung has rolled out the Galaxy S25 Ultra, along with the S25 and S25+, emphasizing enhancements in photography and video creation. Recently, Samsung detailed the various improvements made to the camera system and software of the Galaxy S25 Ultra and the other models in a blog.

    Enhanced Camera Features

    The Galaxy S25 Ultra is equipped with a 50MP ultra-wide sensor that is four times larger than its predecessor. This upgrade allows for capturing intricate details in close-up images and ensures clear pictures of distant subjects. It’s also optimized for fast-moving scenes, making sure that even rapid moments are captured sharply.

    For video enthusiasts, the Galaxy S25 supports 8K resolution at 30fps, with a 0.6x ultra-wide angle option. Transitioning between zoom levels is now smoother thanks to an instant slow-motion engine, and the Pro Video Mode’s new Zoom Rocker UI offers easy zoom speed adjustments.

    New Video Capabilities

    The camera is now packed with six new film-like filters that give your visuals a nostalgic feel reminiscent of vintage film cameras. You can adjust contrast, saturation, and color temperature to match your vision. For serious videographers, the Log Video feature offers an expanded dynamic range for more versatile editing. Users can also download LUTs (Look-Up Tables) from Samsung for use in editing software like DaVinci Resolve and Adobe Premiere Pro.

    The standard 10-bit HDR feature enhances video quality with richer colors and greater depth. Users can also extract snapshots from HDR videos, which are processed to improve color and detail accuracy.

    Creative Photography and Depth Management

    The Expert RAW app comes with a virtual aperture function that allows you to dictate how much of your image is in focus, adjustable from F1.4 to F16, providing DSLR-like depth of field control. It also includes digital ND filters, enabling long exposure photography even in bright conditions.

    The Motion Photo feature has been upgraded to capture 1.5 seconds of video before and after taking a picture, with an option to extend this to three seconds. You can combine these clips into a video, and the AI enhances faces for improved results when capturing groups.

    Smarter Photo Management and Editing Tools

    The Gallery app has been revamped for easier photo retrieval. With enhanced natural language processing and expanded recognition categories, you can swiftly search for images of objects, events, people, or pets.

    User-Friendly Photo Enhancement

    Photo editing has become simpler, thanks to the Photo Remaster feature that employs AI to sharpen blurry images, brighten dim areas, and eliminate noise for clearer visuals. For video, the new audio eraser tool can get rid of unwanted sounds like wind or background noise. The auto-trim feature identifies the key moments in your video, streamlining the editing process.

    Advanced Generative Editing Features

    Generative AI editing has been introduced, offering tools to remove shadows from objects so they blend seamlessly with backgrounds. The sketch conversion feature lets you develop multiple sketch variations from one photo.

    Professional RAW Editing Options

    For those who prefer working with RAW images, the Galaxy S25’s RAW Image Editor has been enhanced to include eight adjustment options for detailed edits. It retains all the original file details, granting users substantial flexibility. Once finished with RAW edits, you can switch to the standard photo editor for additional modifications.

  • Google DeepMind AI Creates Music and Sound for Silent Videos

    Google DeepMind AI Creates Music and Sound for Silent Videos

    Google's DeepMind has unveiled a new AI tool capable of generating background music and sound effects for silent videos. This "video-to-audio" system aims to simplify the video editing process, especially for content creators.

    Currently under development, this technology offers some intriguing capabilities. Here’s an overview of the process:

    User Input

    Creators start by uploading their silent video and can include keywords or phrases to guide the AI in producing the appropriate soundscape. For instance, a silent video featuring someone walking in the dark might benefit from prompts such as “movies, horror films, music, tension, footsteps on concrete” to help the AI grasp the mood and context.

    AI in Action

    DeepMind’s AI model begins by breaking down the video to analyze its visuals. This visual data is then paired with the user-provided text prompts. Through a diffusion model, the AI processes this combined information iteratively, eventually creating background sounds that match the video content.

    Tailoring the Soundscape

    The model can generate different audio options for a single video, allowing creators to select the best match for their project. DeepMind’s system can also take into account the emotional tone of the prompt words. For example, prompts that emphasize “tension” might produce suspenseful background music, whereas prompts like “joyful celebration” could result in more upbeat sounds.

    Looking forward, DeepMind is continuously refining this technology. Future plans include enabling the AI to generate sounds automatically based solely on the video content, eliminating the need for user prompts. Additionally, they aim to enhance the system’s ability to synchronize generated dialogue with the characters’ lip movements in the video.

    This "video-to-audio" technology has the potential to transform video editing, particularly for creators who do not have access to professional audio tools or expertise.
