<div class="header">Shifting</div>
|
|
<div class="exp">
|
|
SSATool can shift a file by entering a time (hour:minutes:seconds.subseconds), by a given number of frames, or by specifying an 'old' time and the new time that it should be shifted to. Shifting by time or frames require a given direction, while time difference already has a direction, given the 2 times.

<ul id="optlist">
|
|
<li>Shift Start/End times: You may choose to only shift the start or end times of each line.</li>
|
|
<li>Replace negative times: If you're shifting backwards and some times end up negative, this option will replace them with a 0 time. After all, who wants to see subtitles before you even watch the video?</li>

|
|
<div class="exp">
|
|
This will create a gradient by making several lines using clip. You may type text in, or you may select a line from the loaded file and click "Copy Selected List Item to Input." If the line has dialogue: ... in it (IE the information for the line and not just the line itself), then select that and click the "Move Selected" button next to the "Before Grad." textbox. This will place that text before each line without actually putting it in the gradient. Fill in the boxes and click Create.

This allows you to easily create cool looking noteboxes from templates contained in the included XML file. Noteboxes can be one or two lines long and each template must specifically give code for each length. See the included file for an example. Templates may be of different resolutions. If a script is loaded which contains PlayResX and/or PlayResY, the generated notebox will be automatically resampled to the script size. Otherwise, the generated notebox will be at the default resolution of the template.

<div class="header">Manual Transform</div>
|
|
<div class="exp">
|
|
How many times have you wished you could use \t on something that doesn't allow it? How many times have you wanted a nonlinear acceleration parameter for \move? Here's a function that will automatically interpolate these things like \t, but it's much more powerful.
|
|
</div>
|
|
|
|
<h3>Zones/the Times Listbox</h3>
|
|
<div class="subinfo">
|
|
<p>Manual Transform is based on zones, which are made up of a start and end time. There must be at least one zone. Each additional zone uses the end time of the previous zone as its start time. So if you entered the times of 0:00:00.00, 0:01:00.00 and 0:02:00.00, there are two zones: one from 0:00:00.00-0:01:00.00 and one from 0:01.00.00-0:02:00.00.</p>
|
|
<p>Based on these different zones, you can have variables which can scale differently at different times. Numbers can scale linearly during one zone and exponentially during another if you like. Text can change between zones.</p>
|
|
<p>If this flexibility is not required, just entering a start time and an end time, making one zone only, will keep things simple.</p>
|
|
</div>
|
|
|
|
<h3>Variables</h3>
|
|
<div class="subinfo">
|
|
<p>This is the data that gets scaled. To add a variable, click the new button and type a name into the popup. You can then edit the values for each time by clicking on the appropriate field in the variable list. You may use either a string or a number. Numbers will be scaled automatically, whereas strings will switch over when a new zone is reached.</p>
|
|
<p>If you enter a string and a number under the same variable, then it will treat both as a string. If you have a string and a number and a number (2 zones), it will print the string until it hits the second zone, where it will then scale between the two numbers. That is to say that if, in the current zone, the start and end variable values are both numbers, the number will be scaled; If one or both are non-numbers, both will be treated as strings.</p>
|
|
<p>Acceleration: You can use linear, logarithmic or exponential acceleration for each variable and zone. Exponential acceleration has 2 forms: ratio^base, which is specified by just entering a number > 1, or base^ratio by specifying exp<i>base</i> (Example: exp2). Specify a log transform by typing log<i>base</i>. If none of these are specified or are incorrectly entered, a linear transform will be used. ASSA itself uses ratio^base for acceleration, so the default behavior (entering a number) works the same as entering that number into \t.</p>

<h3>Other options</h3>

<li>Code is how SSATool puts the variables together to form the text that gets output. To add the line times, use <b>%starttime%</b> and <b>%endtime%</b> in the code. To use a variable in the code, surround the variable name with percentage signs. You may use scripting functions here. If you're scaling an integer, you're going to want to round it with scripting because it will be printed as a decimal otherwise.</li>
|
|
<li>Times: Enter the times for this to span. You must enter at least two times. You may enter more than one time to create different zones where variables can be scaled differently. Times should be the first thing you add.</li>

<div class="header">Kanji timing</div>

|
<div class="exp">
|
|
This function will allow you to time Kanji (or pretty much any other East Asian character set) from Roman letters. You may combine \k times, but this function can't work with \t as it can't be sure how to handle the times. It could also technically be used in reverse, but it's not capable of splitting syllables from the source style.<br /><br />
|
|
You must have your two character sets entered in different styles. The kanji may already be timed, but those times will be overridden if so. Empty syllables will be copied alone, or will be combined with the surrounding syllables if those are to be combined.

<h3>Options</h3>

<ul id="optlist">
|
|
<li>Styles: Select your source and destination styles here. The source style will be used for times and all ASSA code. Destination lines will be overwritten in the list. Note: Any ASSA code appearing before the \k will be directly copied, and ASSA code after the \k is currently not copied at all.</li>
|
|
<li>Start: Brings the first lines of each style into the corresponding text fields.</li>
|
|
<li>Link: When you have selected corresponding syllables, this will pair them up and you will see them appear in the group list.</li>

<li>Unlink last: If you've made a mistake, this will unlink the last pair. You may use it as many times as needed.</li>

<li>Skip source line: Skip the current source line.</li>
|
|
<li>Skip destination line: Skip the current destination line. It won't be modified at all.</li>
|
|
<li>Go back a line: Goes back to the last line for both the source and destination. It does not undo any changes made, but you may redo it.</li>
|

<li>Up/down arrows: Select more or less text from the source, respectively. The source text is locked so it can not be split, but you may combine syllables from it.</li>

<div class="header">Karaoke effects</div>
|
|
<div class="exp">
|
|
The karaoke effect generator is a complex karaoke effects automator. In simple terms, it could be called a "\k to \t converter," though it is not limited to transformations. You have several variables (listed below) and scripting functions (listed further below in another section) available to use in template effects. You also have "raw code," which will just dump anything you put in there into the SSA. You can use variables in any of the effect fields. You may use raw code to accomplish anything that the other effects can do. Other effect templates are there just to make it easier for you to make presets. There's an effects editor to add your own presets available under the Effects menu.
|
|
</div>
|
|
|
|
|
|
|
|
<h3>Layers</h3>
|
|
<div class="subinfo">
|
|
<p>Layers are the basis of the effects system. They are, in essence, one of the base elements of ASSA itself. The simplest implementation of a layer is a single dialogue line. That's it. The subtitler program reads each line and decides where each line goes, and in what order they go.</p>
|
|
<p>However, in SSATool, layers are different than how SSA itself looks at them. A layer is how SSATool processes a line in order to add effects. Depending on the complexity of an effect, it may take from one to several lines to accomplish. That is, you might have two or three or even dozens of dialogue lines composing what we see as one line! So each layer in SSATool will add another dialogue line with the same text but potentially different overrides. But to make things even more confusing, there's an exception: Layer-Per-Syllable. What happens if you want to do something to a syllable in a karaoke as its "turn" comes up, but the command to do what you want to do is a command that affects the whole dialogue line, even if you use \r? You often have to make a dialogue line corresponding to each syllable.</p>
|
|
<p>This is what layer-per-syllable does. It will dynamically create a new dialogue line (layer) for each syllable. You're typically going to want to see each line only for the syllable it corresponds to, because that's the basic reason why layer-per-syllable exists. To accomplish that, you're going to want to have a couple of effects in addition to your transformation code. These extra effects will be to make the line invisible except at the corresponding syllable. You'll use conditions (explained below) to apply alpha codes before and after this syllable. A sample layer-per-syllable project file should be bundled to show you how to go about it. Don't use it as a basis every time you want to do layer-per-syllable, because it will ensure that you don't understand how the process works. To make karaoke, you must first understand how ASSA renders karaoke.</p>
|
|
<p>To enable layer-per-syllable mode, simply add a layer and make sure the Layer-per-Syllable checkbox is clicked. You may combine layer-per-syllable layers together or with fixed layers if you like.</p>
|
|
</div>
|
|
|
|
<h3>Conditions</h3>
|
|
<div class="subinfo">
|
|
<p>There are two types of conditions in the karaoke effects generator: effect conditions and layer conditions. They both do the same thing, but they work on a different scope. For both, you enter two things to compare. These things may be numbers or strings, and you may use variables and scripting functions (listed below).</p>
|
|
<ul id="optlist">
|
|
<br /><li>With effect conditions, each condition must be true for that effect to be applied, or it will just be skipped for that syllable. There is no condition checking for effects on a per-line scope, meaning the conditions are only checked per syllable, not per line. This is the more flexible option of the two.</li>
|
|
<br /><li>With layer conditions, each of these must work out for all of the effects in that layer to be applied. By default, if this is not met, there will be no dialogue line created at all. However, when you create your layer conditions, you may option to create the dialogue line WITHOUT effects if the conditions are not met. For fixed layers, the option is called, "Add line unchanged if layer conditions not met." If you're using layer-per-syllable, just that option will add the line several times (once per syllable) if the layer conditions aren't met, so you'll also want to enable the option, "Only add it once."</li>
|
|
</ul>
|
|
</div>
|
|
|
|
<h3>Layout</h3>
|
|
<div class="subinfo">
|
|
<p>The layout of the karaoke effects section can be a little confusing at first. At the left, there's a treeview. This holds information about all layers and effects. You can add a layer via the button under it. Once you have added and selected a layer, you may add effects to it through that button. You may drag items around the treeview to reorder them or to move effects to a different layer. You may duplicate or remove layers or effects through the corresponding buttons.</p>
|
|
<p>When you select a layer in the treeview, the layer options page automatically shows up. Here, you can add layer conditions or change the options for the layer. When you click on an effect, you get a tabbed setup where you can view the options for that effect or the conditions. To change an option for an effect, just click on the corresponding field.</p>

|
</div>

<h3>Options</h3>
|
|
<div class="subinfo">
|
|
<ul id="optlist">
|
|
<li>Don't add the syllable text: This will leave out the actual text for the syllable. You may add it yourself in your effects using the %text% variable. This allows you to split a \k if you like.</li>

|
<li>Remove \k: This will remove \k, \K, \ko and \kf after applying effects. Keep a backup file before you use this option in case timing needs to be changed later.</li>
|
|
<li>Add line unchanged if conditions not met: If layer conditions aren't met, add the dialogue line with no effects. You could get missing dialogue lines without this option.</li>
|
|
<li>Only add it once: An extension of the above for layer-per-syllable mode to prevent dialogue lines from being added multiple times when layer conditions are not met.</li>
|
|
<li>Layer-per-Syllable: Enable Layer-per-Syllable mode for this layer. See the explanation above.</li>
|
|
<li>Repetitions: This only applies to non-LPS layers. The layer will be repeated this amount of times. It only applies to karaoke lines, not regular dialogue lines.</li>

<h3>Effect files</h3>
|
|
<div class="subinfo">
|
|
Effect files are XML files that hold all preset effects except for "raw code," which is built in. They use the extension exml. You may edit them in a text editor by using the bundled effects as a template. There's also an effects editor in the program to write them for you.
|
|
</div><br />
|
|
|
|
<h3>Project files</h3>
|
|
<div class="subinfo">
|
|
Project files are also XML files, but they are in a different format than the effect files. They contain all layer, filter and condition information as well as the filename to the loaded SSA, if applicable. They are not a script - they do not keep track of your commands, but merely karaoke effects information. They may be edited in a text editor, but I only recommend doing that if you want to make a slight modification to an existing file.

<div class="box">
|
|
<div class="header">File Encoding</div>
|
|
SSATool will open most common file encodings including ANSI (using your local codepage), Shift-JIS, and Unicode in 1, 2, or 4 octet versions. Some encodings, such as Shift-JIS are notoriously hard to detect, so if your file includes Japanese text and you're unsure of the encoding, please make sure to find out, or that it displays correctly if you use the open file option without the SJIS.<br /><br />
|
|
As of version 4.1, SSATool employs extremely simple algorithms for attempting to detect Shift-JIS and EUC-JP. If a file is under 4KB, 100 or more characters detected with either encoding will trigger a prompt asking to reload using that encoding. If the file is 4KB-8KB, the threshold is 300, and if the file is 8KB or more, 600.
