最近，我非常喜欢使用 Grok。我特别喜欢截取低分辨率视频中最重要的部分，然后用我找到的一个提示词把它们转换成高分辨率图片。

Lately, I've really enjoyed using Grok. I especially like taking screenshots of the most important parts of low-resolution videos and then using a prompt I found to convert them to high resolution. Here is the Prompt, you can try with a low Resolution picture. “Let the posture, angle, framing, perspective, facial expression, hair - everything - remain exactly the same. The character and the environment must not change in any way. The color tone and overall color palette of the image must remain unchanged. Do not modify, reinterpret, replace, or introduce any new visual elements. The image must be recreated as if it was shot on a Sony A1, using an 85mm f1.4 lens, at f1.6, ISO 100, 1/200 shutter speed, cinematic shallow depth of field, perfect facial focus, and an editorial-neutral color profile. This Sony A1 + 85mm f1.4 setup is mandatory. The final image must clearly look like premium full-frame Sony A1 quality. Lighting must match the exact direction, angle, and mood of the reference photo. Upgrade the lighting into a cinematic, subject-focused style: soft directional light, warm highlights, cool shadows, deeper contrast, expanded dynamic range, micro-contrast boost, smooth gradations, and zero harsh shadows. Maintain neutral premium color tone, cinematic contrast curve, natural saturation, real skin texture [not plastic], and subtle film grain. No fake glow, no runway lighting, no oversmoothing. Render in 4K resolution, 10-bit color, cinematic editorial style, premium clarity, portrait crop, and keep the original environmental vibe untouched. Re-render the subject with improved realism, depth, texture, and lighting while keeping identity and background fully preserved.”
