THE DEAL
这门课的
三条规则
三条规则
知识在线上学，问题在线下解决。
不打卡、无监督——想学的人自己往前学。
不打卡、无监督——想学的人自己往前学。
RULE 01
知识在线上，问题在线下
网站自学：图文卡 + 跟练 + 自测。线下课不重复教材，只做三件事——演示实战里容易出的问题、回答你自学攒下的问题、解决你卡住的地方。
RULE 02
两条线：基础线 + 高级线
基础线从零到出片，自学 + 线下课 + 收官晚的官方认证考试。高级线给有基础的人，4 场进阶主题，不点名、不强制，哪场感兴趣来哪场。
RULE 03
一个晚上一个语言场
周三中文场、周四英文场，都是 18:30–20:30，都在这间机房，内容一样，按语言偏好任选一场跟到底。
THE DEAL
This course's
three rules
three rules
Knowledge lives online; problems get solved in person.
No check-ins, no supervision — the ones who want to learn move ahead on their own.
No check-ins, no supervision — the ones who want to learn move ahead on their own.
RULE 01
Knowledge online, problems in person
Self-study on the site: reading cards + exercises + self-tests. Class time never repeats the textbook — it does three things: demo the mistakes that show up in real work, answer the questions you've saved up, unstick wherever you're blocked.
RULE 02
Two tracks: basics + advanced
The basics track goes from zero to a finished film: self-study + in-person classes + the official certification exam on the closing night. The advanced track is for people with some base — 4 advanced sessions, no roll call, no obligation, come to whichever interests you.
RULE 03
One night, one language track
Wednesday Chinese, Thursday English, both 18:30–20:30, both in this Mac lab, same content — pick the language track you prefer and stay with it.

W7 · 10-28
Editing basics
Solves: getting media into a project, picking the takes you need, cutting clean, ordering the story — and getting a quick export out.
Before class: GS Getting Started + L7 project setup + L1 rough cut + L2 fine cut + L3 audio & quick export
You leave with: a repeatable rough cut → fine cut workflow, plus a quick export path.

W9 · 11-11
Grading
Solves: getting the image 'correct' first — what the lift, gamma and gain wheels each control; then local adjustments.
Before class: L4 primary + L5 secondary + L6 finishing & management
You leave with: reading the scopes, not guessing by eye.

The advanced track, taken apart
10-21 · Session 1
Picture-tech literacy
Solves: what the jargon actually means — resolution ≠ sharpness · 8/10-bit and banding · 4:2:0 and keying edges · bitrate and blocky artifacts · why Log looks flat · why you can't slap on any LUT · why colours shift after export.
Format: every term = one phenomenon you can see in Resolve (a hands-on demo class, not a theory class).

Fine-grain craft
Solves: making the image more 'refined' — sharpening and detail enhancement, advanced keying (why some edges never come clean).

film looks
film looks
Solves: 'do you really want the film look' — if yes, how to get it; where colour management sits in the chain.
Builds on Session 1: Rec.709 / sRGB / P3 — why colours change after export. You leave with judgement, not a LUT to copy.

12-02 · Session 4
AI-assisted editing & grading
Solves: how AI tools fit into a real pipeline, where they genuinely save time, where a human still decides.
The last part of the session: how to use your own personal agent to cheaply handle simple operations inside the software.

WHITE POINT · 1/2 · 什么是白点
「什么算是白」是被规定的
现实里的白没有标准答案。
数字影像必须挑一个参考白点（CIE 色度坐标）。
换标准 = 换白点 = 整张片子偏色。
数字影像必须挑一个参考白点（CIE 色度坐标）。
换标准 = 换白点 = 整张片子偏色。
「D」是什么
日光标准光源（Daylight），数字 ≈ 色温：D50 → 5000K、D55 → 5500K、D65 → 6500K。
为什么标准用坐标而不是只写 K
色温一样、色调可以不同。
标准写的是 x / y 坐标。
影院例外：DCI-P3 白点约 6300K，不等于 D65。
标准写的是 x / y 坐标。
影院例外：DCI-P3 白点约 6300K，不等于 D65。
D50 ≈ 5000K：印刷 / ICC 连接空间。 | D65 ≈ 6500K：sRGB、709、2020 的白点。
WHITE POINT · 1/2 · what a white point is
What counts as 'white' is decided by convention
There is no standard answer for white in reality.
Digital imaging has to pick a reference white point (CIE chromaticity coordinates).
Change the standard = change the white = the whole film shifts colour.
Digital imaging has to pick a reference white point (CIE chromaticity coordinates).
Change the standard = change the white = the whole film shifts colour.
What the 'D' means
Daylight standard illuminants, number ≈ colour temperature: D50 → 5000K, D55 → 5500K, D65 → 6500K.
Why standards write coordinates, not just K
Same colour temperature, different tint is possible.
Standards write x / y coordinates.
The cinema exception: the DCI-P3 white point is about 6300K, not D65.
Standards write x / y coordinates.
The cinema exception: the DCI-P3 white point is about 6300K, not D65.

WHITE POINT · 2/2 · 对不上会怎样
白点不匹配 = 整张片子偏色
症状 ①
整体偏冷 / 偏暖
6300K 素材放进 6500K 链路：所有颜色一起被推走。
症状 ②
「导出后颜色变了」
先查白点，再查 gamma，再查色域。
症状 ③
同一个 grade 两台设备不一样
两台设备白点不同，调出的「白」就不是白。
容易混
相机白平衡 ≠ 后期白点
拍摄时给传感器参考 vs 后期色彩管理按哪个标准解释。
实操
在链路上对齐
输入 / 时间线 / 输出三处都要对；跨标准要转换。
一句话
白点是基准，不是滤镜
它只决定「什么算白、其余往哪偏」。
回到五边形：白点属于 Color Volume 顶点。
WHITE POINT · 2/2 · what happens when they don't match
Mismatched white point = the whole film drifts
Symptom ①
Uniform cool / warm cast
6300K footage in a 6500K chain: every colour gets pushed along together.
Symptom ②
'Colours changed after export'
Check the white point first, then gamma, then gamut.
Symptom ③
Same grade, two devices differ
Two devices, two white points — the 'white' you graded to isn't white.
Easily confused
Camera white balance ≠ post white point
A reference for the sensor at shoot time vs which standard post interprets by.
In practice
Align it along the chain
Input / timeline / output — all three must match; convert when crossing standards.
In one line
A white point is a reference, not a filter
It only decides what counts as white — and which way everything else leans.
Back to the pentagon: the white point lives on the Colour Volume vertex.

FAQ
常见问题速查
Q1
零基础真能考过官方认证吗？
考试内容和网站自学同源。教材跟练卡过完、练习做完，就是按这个考试准备的。
Q2
我要用什么电脑？
能装 DaVinci Resolve 就行，免费版够用整个课程。跑不动就用这间机房。
Q3
能线上参加吗？
教学场次有腾讯会议直播和录播，入口在 Workshop 工作台。认证考试必须本人到场。
Q4
缺席一次怎么办？
教学场次不计出勤，错过后看录播并完成自学；只有认证考试要求到场。
Q5
高级线要什么基础？
建议先跟基础线打底。已经会剪、只想深入调色和风格的，可以直接挑高级场来。
Q6
还有问题找谁？
群里直接 @ 我，我会很快回；也可以发公邮 AFCT.Tech@xjtlu.edu.cn（工作日 48 小时内回）。
FAQ
FAQ quick reference
Q1
Can a total beginner really pass the official exam?
The exam draws from the same material as the site. Finish the textbook cards and exercises and you've been preparing for exactly this exam.
Q2
What computer do I need?
Anything that runs DaVinci Resolve; the free version covers the whole course. If yours can't, use this Mac lab.
Q3
Can I join online?
Teaching sessions stream on Tencent Meeting with recordings; the entry is on the Workshop hub. The certification exam is in person only.
Q4
What if I miss one?
Teaching sessions don't count attendance — watch the recording and do the self-study; only the certification exam requires you there.
Q5
Does the advanced track assume experience?
The basics track first is recommended. If you already edit and want depth in grading and looks, pick the advanced sessions directly.
Q6
Who do I ask?
@ me in the group — I reply fast; or write to AFCT.Tech@xjtlu.edu.cn (within 48 hours on weekdays).
真实问答 · 中文场现场提问 · 2026-10-14
同学们昨晚问的——答案在这里
中文场现场被问 · 英文场收录进 FAQ 页
现场监视器看着很好，为什么导出到客户的电脑上不一样？
画面最终什么样，取决于甲方用什么容器在看——最好的办法是把甲方请到你的剪辑室，跟你看同一块屏幕。都给 1080P，他套个 LUT 美化两下当然好看，但你实际拿到的画面完全不一样。这种工作流要带 show LUT 去现场，避免现场的摄影师在他的监视器上犯下后期无法挽回的错误。
两个语言场
英文场讲的内容跟中文场一样吗？
一样的。之后周四是英文场，内容都一样——我上两遍，一遍中文，一遍英文。
自学方法
已经完整看过一遍了，想再精进怎么办？
开着 workshop 页面自己做一遍，做完一步勾一步；全部过完有一张自测卡，看看你哪里懂了、哪里没懂。
剪辑软件
这些剪辑软件到底有什么区别？
很简单，没有区别。本质一样——不看用的是什么，只看最后得到的结果是不是想要的。
认证考试
考试能不能提前来考？
可以，早点来考完。我四五点就在这里，4 点半开始在这里等你们；6 点之前考完，再过去上课。（她当场的口头安排，不是固定排期）

REAL Q&A · FROM YESTERDAY'S SESSION
Questions your classmates asked — the answers
MONITOR & EXPORT
It looks right on my monitor — why is the export different on their machine?
What your picture finally looks like depends on what container the client is viewing it in. So the best move: invite the client into your edit room and look at the same screen together. Everyone delivers 1080p — if they throw a LUT on it and pretty it up, of course it looks nice, but what you actually got is a different picture. So in this workflow I recommend bringing your own show LUT to set — so the on-set camera operator doesn't make, on a good-looking monitor, mistakes that post can't undo.
THE ENGLISH SESSION
Is the English session the same as the Chinese one?
Yes. Thursdays from now on are all in English, and the content is the same — I teach it twice: once in Chinese, once in English.
GOING DEEPER
I already went through it once — how do I get better?
Open the workshop site beside you and do it yourself, one step at a time — tick each step as you finish it. When you've been through the whole course, there's a self-test card at the end: see what you know and what you don't yet.
WHICH APP
What's actually the difference between all these editing apps?
Simple — there is no difference. The essence is the same: don't look at what you're using; look at whether the final result is what you wanted.
EXAM DAY
Can I take the exam before class starts?
Yes — come early and get it done before 6, then head straight to class. I'm here from around four, and I'll start waiting here at 4:30. (her on-the-spot offer, not a fixed schedule)
From yesterday's live session — got more questions? @ me in the group.
