![]() Next, the way \k effects are handled is using a “switchpoints” algorithm. This will also explain a funny “artifact” some karaokers might have seen when using \kf with vertical karaoke.įirst, while TextSub does have a function that should tell whether a line is animated or not (presumably so it could avoid re-rendering static lines for every frame) that function is empty, it just says “return true ”, so every line is always considered animated, no matter what’s in it. Also, everything that goes for \k also goes for \kf, \K and \ko. This discussion only covers TextSub (VSFilter), I don’t know what other renderers do and their use is still very limited. This is a repost of something I wrote earlier on the AnimeSuki forums, in relation to a discussion of how much CPU time various kinds of karaoke effects take to render. I hope this has helped you and gave you some insight into how I work with Aegisub.Why rendering \k and \kf effects is fast in VSFilter I’ll later add the code for the line from the gif and explain it a bit more. T1 is the start time and t2 is the end time. For this effect I made use of the tag \t which has the following syntax (copied from the documentation): As you can see, I changed the secondary colour to the opposite colour to match with the background. This is an example of a single karaoke line where the video background was first white, then black and then white again. Sometimes it cuts off too much and you have to adjust the \clip tags by yourself. Its interface looks like this:Īs you can see there are quite some options to play around with and it has following modes: smooth, smooth (vertical), by character and by syllable. ![]() You might have seen one of those effects where a line starts with one color and ends with the other one like this:įor this I use a script called Gradient Factory which can be found in the Aegisub forum. Here you can find a script called “Add tags” which lets you do that so that you don’t have to do it manually for each line as Aegisub doesn’t have this function. I often like to add something like a fade in or blur for all lines. This is a function which I really often use. If you have already added the karaoke tags for one of those lines, you can simply copy the line’s content in the editor box to the other lines and adjust the timings for all the karaoke tags at once by holding CTRL while dragging the first karaoke marker. I’ll add a screenshot later and maybe an example of a full working karaoke script.Īdjust all karaoke markers of a line at once ![]() Now I can select the rest by using Subtitle > Select Lines and a window opens where I use the following options:Īnd then I just have to select the style “bottom”! All then I have to do is to select the style “bottom” and voilà, the first half is done. Automation > Select overlaps does what its name suggests. The difference in them is that style “up” is aligned at position 1 with higher vertical margin than style “bottom” (choose at least something with the difference of 55 or more, depending on the font size) which is aligned at position 3.Īssigning those styles to the right lines is simple and I use the fact that their timings overlap. I’m someone who likes to make karaoke videos from time to time which are in this style:įor this I define two different styles, one called “up” for the upper line and one called “bottom” for the bottom line. If you don’t mind the mini lags the latest stable version is fine. I’m using the latest one, build r8898 and until now I didn’t run into any problems. In addition, I recommend you to use the latest experimental build or at least build r8841 because there smoother auto saving was introduced. In this post I want to introduce to you useful functions and scripts I like to use.Īs it already says in the tooltip, it automatically commits all your changes, especially if you often forget to press the hotkey for committing like me. Aegisub is the best tool for fancy subtitles and widely used by the fansubbing scene as it allows many text transformations, e.g.
