使用CRF（恒定速率因子）和编码预设调整视频质量，从无损到高压缩
用三种语言从你的代码中调用此工具。
# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'https://api.elysiatools.com/api/upload/presign/video-quality-adjust' \
-H 'Content-Type: application/json' \
-d '{"filename":"videoFile.ext","contentType":"application/octet-stream","size":12345}'
# 2) PUT the file bytes directly to the presigned uploadUrl
curl -X PUT '<presigned uploadUrl>' \
--data-binary @/path/to/file.ext
# 3) Call the tool, passing the returned storageKey for each file field
curl -X POST 'https://api.elysiatools.com/zh/api/tools/video-quality-adjust' \
-F 'videoFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'qualityPreset=good' \
-F 'customCrf=23' \
-F 'customPreset=medium' \
-F 'tune=film' \
-F 'scalePercent=100' \
-F 'outputFormat=mp4'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
