How to improve OCR accuracy
Practical tips: resolution, contrast, cropping, language choice, and when to use a clearer source image.
Prefer originals or high-resolution screenshots; avoid re-compressing. Larger text in the frame is more reliable.
Dark text on a light background helps; crop away clutter before recognizing.
Pick English, Chinese, or Chinese+English to match the image — the wrong language pack produces garbage.
If results stay poor, the image may be beyond classic OCR; use a clearer source or a layout-aware tool.
