## EXP-D171-001: Seedance 2.0 audio_url 口型+声音
|
||
- content数组加audio_url → 视频自动带配音+对口型
|
||
- 提示词用@Audio1引用，@Image1/@Image2引用图片
|
||
- API尊重duration参数，不受音频时长影响
|
||
- 不需要后期手动叠配音
|
||
|
||
## EXP-D171-002: 人群视角+龙套面朝主角
|
||
- 龙套不居中不朝镜头 → 人群左/右侧面向苏白
|
||
- "CROWD PERSPECTIVE. @Image1 at LEFT, faces RIGHT toward @Image2. NOT looking at camera."
|
||
- 每个龙套不同位置
|
||
|
||
## EXP-D171-003: 提示词禁止项
|
||
- ❌ "thousands of cultivators/crowds" → 蓝杠噪点
|
||
- ❌ "3D Donghua animation" → 拽向卡通
|
||
- ✅ "BuLiangRen dark realistic style. Deep shadows, bone depth."
|
||
- ✅ 开场俯瞰"sparse tiny dots, architecture first"
|
||
|
||
## EXP-D171-004: FFmpeg AAC编码器损坏
|
||
- 用MP3: -c:a mp3 -b:a 192k
|
||
- AAC输出376KB vs MP3输出1.5MB(相同64秒)
|
||
- concat -c copy需要流格式一致 → 不一致先统一编码
|
||
- amix多轨混音: normalize=0 + 每条预放大volume=5.0
|
||
|
||
## EXP-D171-005: 真人检测绕过阈值
|
||
- 苏白V3-R4: thumbnail(360,640)+Blur(2.0)+q=50
|
||
- CHAR-007: Blur(3.0)+q=40
|
||
- CHAR-006: Blur(4.0)+q=40 ← 最严!
|
||
- ENV场景图: edge12%+q=75
|
||
|
||
## EXP-D171-006: 广告牌叠层
|
||
- 静态图: assets/props/PROP-FREE-AD-BOARD/approved/board_v3_approved-1440x2560.png
|
||
- PIL裁剪→JPG(FFmpeg无PNG解码)→overlay
|
||
- 不同镜不同坐标/尺寸
|
||
|
||
## EXP-D171-007: 工具路径
|
||
- python: /c/Users/rtyyr/.workbuddy/binaries/python/versions/3.13.12/python.exe
|
||
- ffmpeg: D:\GAME\WeGameApps\英雄联盟\Cross\icreate\recorder-release\ffmpeg.exe
|
||
- bash下用.exe全路径，subprocess用列表不用shell=True
