Stable Diffusion Prompt Word Guide | Basic tutorial

[00:00] what do all those symbols in stable

[00:01] diffusion really mean how can we write

[00:03] prompt words so that the pictures we get

[00:06] are more what we want when you see those

[00:08] complex stable diffusion prompt words do

[00:10] you feel confused too don't worry this

[00:13] video will help you with all kinds of

[00:15] problems when you fill in prompts first

[00:18] off let's check out the basic principle

[00:20] of prompt words prompt words are

[00:22] separated by commas and you can put

[00:24] prompt words on different lines but you

[00:26] still need a comma at the end of each

[00:28] line as for weight each prompt word has

[00:31] a default weight of one but the words at

[00:33] the front get a higher weight so put

[00:36] important words at the front if you can

[00:38] finally keep the number of prompt words

[00:40] within 75 if there are too many words

[00:43] they won't have much control over the

[00:45] picture next up let's talk about what

[00:48] each symbol means first off there are

[00:50] parentheses square brackets and curly

[00:53] braces these are mainly used to tweak

[00:55] the weights of keywords when you put a

[00:58] hint word in parentheses it's weight

[01:00] becomes 1.1 you can use up to three

[01:02] parentheses at the same time when n

[01:05] parentheses are used the weight of the

[01:07] hint is 1.1 to the power of n curly

[01:10] braces are also for increasing the

[01:11] weight of a hint curly braces are used

[01:14] to increase weight too each layer of

[01:16] curly braces increases the weight by

[01:18] 0.05 the adjustment with curly braces is

[01:21] much smaller than that with parentheses

[01:24] square brackets are used to decrease

[01:26] weight one square bracket makes the

[01:27] weight of a hint word 0 point 9 times

[01:30] less three square brackets make the

[01:32] weight 0.7 to 9 the easiest way to

[01:36] adjust weights is to add a colon after

[01:38] the hint word in parenthesis and then

[01:40] fill in the desired weight value

[01:42] directly after the colon It's

[01:43] recommended to set this value between

[01:46] 0.3 and 1.5 for example if you enter

[01:49] cherry blossoms kittens green leaves and

[01:52] set a different weight value for cherry

[01:54] blossoms you can control the proportion

[01:56] of cherry blossoms in the whole picture

[01:58] the pointed bracket are mainly used to

[02:01] call Laura the format is Laura trigger

[02:04] word weight value after calling Laura

[02:07] images with specific features can be

[02:09] generated it should be noted that in

[02:11] tensor Laura tritter words can be

[02:13] directly used with one click which is

[02:16] very convenient underscores act as a

[02:18] link to make the keywords more closely

[02:20] connected for example a milk cake might

[02:23] be understood by stable diffusion as a

[02:25] glass of milk and a cake but if milk and

[02:28] Cake are connected by Under scores then

[02:30] stable diffusion will understand milk

[02:32] and cake as a whole next let's check out

[02:35] some Advanced syntax now how do we

[02:38] control when a prompt kicks in first off

[02:40] you can use a combo of square brackets

[02:43] and colons there's a number after

[02:45] cologne it means the prompt starts

[02:47] rendering from that point a double

[02:50] cologne that means the prompt in

[02:51] parentheses renders till that point when

[02:55] there's one prompt it's like this but

[02:57] there can be two prompts in parentheses

[03:00] like this the two prompts are separated

[03:02] by a cologne so for the first 70% of the

[03:06] rendering stone is on and for the next

[03:08] 30% flower is on if the two prompts in

[03:12] parentheses are separated by a vertical

[03:14] line like this it's alternate sampling

[03:17] so red hair and blue hair prompts

[03:20] alternately and you'll end up with red

[03:22] and blue hair after you get the hang of

[03:24] the basic syntax let's check out the

[03:26] recommended way to describe the overall

[03:28] prompt words picture quality and

[03:31] painting style words have a big impact

[03:33] on the overall look of the picture so

[03:35] it's a good idea to write them on the

[03:37] top I've got some tips on picture

[03:39] quality prompts mostly they work for

[03:42] everything but for different styles of

[03:44] pictures there will be some specific

[03:46] quality words too like pixel style Pixar

[03:49] style ink painting style and so on add a

[03:52] comma at the end of this and you can

[03:54] start a new line if you want then

[03:56] there's the description of the main part

[03:58] of the picture my character age

[04:00] hairstyle hair color what they're doing

[04:03] and so on the more detailed you are the

[04:06] more accurate the generated picture will

[04:08] be add a comma after writing and start a

[04:11] new line next up is the description of

[04:13] the lighting in the environment like a

[04:15] Snowy Evening or a Sunny Meadow add a

[04:18] description of the lighting used at the

[04:20] end of this the last line is for adding

[04:23] the trigger word of the Laura you want

[04:25] to use after positive prompts fill in

[04:28] the negative prompts

[04:30] generally just filling in some general

[04:32] negative prompt is fine if you're using

[04:35] the flux model it won't let you fill in

[04:37] negative prompts on your own when you're

[04:39] using tensor's classic workbench you can

[04:42] just fill in the prompts in the language

[04:44] you know after that click the

[04:46] translation button right below when

[04:49] you're out of ideas for the prompts you

[04:51] can choose to generate them randomly or

[04:53] by recognizing pictures oh and you can

[04:56] also check out the posts recommended on

[04:58] the homepage to get some

[05:00] inspiration there are a bunch of tensor

[05:02] models for you to pick from all of

[05:04] tensor's models are online no need to

[05:07] download they're one click and don't ask

[05:10] too much of your graphics card best of

[05:12] all they're free you can get free
