如何線上修復模糊影片
模糊影片令人沮喪——無論是重要錄影、舊家庭影片，或是專案所需的素材。好消息：AI影片增強能從模糊來源中恢復驚人的細節量，而且完全可以線上完成。
影片模糊的常見原因
低解析度
低解析度影片包含較少像素。放大可能改善觀感，但不保證找回遺失細節。
過度壓縮
在通訊軟體分享或從網路下載的影片通常被大量壓縮，產生塊狀偽影和模糊細節。AI可以重建部分遺失的資訊。
手震與動態模糊
相機或主體移動可能造成模糊，嚴重動態模糊在增強後仍可能存在。
光線不足與雜訊
低光源影片通常看起來顆粒粗且柔和。擴散模型可以在重建底層細節的同時降低雜訊，提升整體清晰度。
為什麼AI增強有效
AI 會根據現有影格推測合理細節。畫面更清楚不表示推測出的臉孔、紋理或文字符合事實。
ClearFrame 使用 ReCaVSR 擴散模型與時間處理。擴散模型也可能生成錯誤細節或瑕疵，請以動態預覽比較。
ClearFrame如何修復模糊影片
上傳您的模糊影片
登入後上傳最大 500 MiB 的 MP4、MOV、AVI、MKV 或 WebM，再取得免費片段預覽。
檢視AI預覽
自行選擇原片中的 1 秒區間，產生免費的前後對比預覽，再決定是否購買 credits。
增強並下載
單次 US$2.99（適用稅金另計），處理一支最長 30 秒、最高 30 FPS／1080p 輸入的影片。標準畫質增強，免訂閱、免買點數包。
最佳效果提示
- 使用您能找到的最高品質來源——AI在有更多資訊的基礎上效果更好
- 可先用 240p–480p 短片預覽，請比較實際細節，而不只看解析度數字。
- 短片段測試最便宜——在增強長影片前先試試有代表性的片段
- 壓縮瑕疵可能改善或保留，請以自己的免費預覽判斷。
What can improve, and what cannot
A soft or compressed clip may look clearer after enhancement. The result depends on the source; a larger frame does not prove that missing detail has been recovered.
Use the free preview to compare the same moment in motion. Check faces, text and edges before paying for the full video.
Low-resolution footage
Edges and textures may appear clearer when enlarged. Fine detail can also be inferred incorrectly.
Compressed clips
Some blocky or soft areas may become less distracting. Start with the least compressed original available.
Faces and text
Inspect these closely: sharpening an appearance does not make an inferred face or character accurate.
Movement
Watch the preview at normal speed to check for changing textures, edge artifacts or flicker.
Set realistic expectations
Enhancement can improve appearance, but some recordings contain too little information for a useful result.
- Severe motion blur or missed focus may remain blurry.
- Overexposed or completely dark regions cannot be reliably reconstructed.
- AI can invent plausible detail; do not use generated detail to identify a person or read evidence.
- ClearFrame is not a 4K export service. Check the actual preview dimensions before purchasing.
Questions before you upload
Can I make a blurry video perfectly sharp?
Not reliably. Mild softness may improve; severe blur and missing detail may not. The free preview lets you judge your own clip.
Is the full enhancement free?
單次 US$2.99（適用稅金另計），處理一支最長 30 秒、最高 30 FPS／1080p 輸入的影片。標準畫質增強，免訂閱、免買點數包。
How much will my clip cost?
One credit covers 300 frames, rounded up per job. A 30-second clip at 30 fps uses 3 credits; at 60 fps it uses 6. Check the estimate before starting.
Do I need an account or a GPU?
An account is required to upload. Processing runs in the cloud, so no local GPU or desktop installation is required.
