Or time in aegisub. Import into after effects and do all the typesetting there. After Effects also could be use to setup an encoding farm, but thats going to far.

[max2k]

Yes you could use AFX for encoding if you don't care about unnecessary color conversion...

But the Questions Kudo Shinchi aks with his little Conan avatatar are kickstarting my paranoia, because of a Conan kara that I done and that has still to be relased...

I have a problem when using my lead in effect. The spacing on my text is getting messed up and I cannot figure out what is doing it.
I've only been using Aegisub for about a week now so I can't really figure it out.
Here's a screenshot:


This is the lead-in code:

Comment: 0,0:00:00.00,0:00:00.00,Romaji,,0000,0000,0000,template char,!char_counter(1)!!retime("start2syl",-1000+(ci[1]-1)*42,0)!{\an5\fad(500,0)\3c&HFFFFFF&\move(!$center-100!,$middle,$center,$middle,0,500)\fscx50\fscy50\frx180\t(0,700,0.8,\frx0\fscx100\fscy100\3c&H836C4F&)}

The effect and everything works fine, it's just the text spacing gets messed up.
I want the top text to be like the bottom, but with the lead-in effect.

--Forgot to add that I'm keeping the text there by using this:

Comment: 1,0:00:00.00,0:00:00.00,Romaji,,0000,0000,0000,template char,!retime("syl2end",-$dur,-500+syl.i*50)!{\fad(0,500)\an5\pos($center,$middle)}

Are you sure the Script Resolution (File->Properties in Aegisub) is the same as the video resolution?

Lol, that fixed it. Thanks alot!

I see the scale effect of Ichigo Mashimaro OP by [r0r1p0p] very nice

Video
http://www.megavideo.com/?d=45QMS1IN
http://www.megaupload.com/?d=45QMS1IN

What code can i create the shape scale up and down following line.width for once line, similar that video. I dont know how to get any value of previous line or next line to current line I tryed, it's not working (certainly! ) but i dont know how to fix

!retime("line", 0, line.i+1.start_time-line.end_time)!{\an5\fscx100\fscy100\t(!line.end_time!, !line.i+1.start_time!, \fscx!100*(nextline.scale_x/line.scale_x)!)\c&H292ABC&\bord0\shad0\1a&H80\be2\pos($lcenter, $lmiddle)}{\p1}m 0 5 l 0 35 l 400 35 l 400 5 l 0 5

[jfs]

That's one of the few things that are impossible (or at least absurdly hard) to do in kara-templater, accessing other lines' data.
The reason is that the other lines aren't even loaded at the time the current line is being processed: One input line is read, output lines for it are generated and stored, the input line is marked as "used" and then discarded from memory, only remaining in the file. Then processing continues on the next line.

What I'd suggest is simply changing the timing of the original lines to suit what you want to do. Remember that it is legal to have the last karaoke syllable on a line end before the line ends. (You can also end a line before the last syllable ends.)
Another advantage of changing the timing of the lines by hand is that you can adjust it slightly for something that may give a better visual effect too. (Like, timing a transition to a beat in the music, or similar.)

I think i shall try it in lua

[LelouchVII]

This looks quite interesting. jofori89 If u manage to make this, maybe you could share the script?(or at least the part of it that describes the scale?)

[jofori89]

I'm studying about lua so i'll try it in lua but not sure it will work cuz i'm newbie

[LelouchVII]

Hm.. I haven't scripted much in lua but I have tried similar stuff in python (other generators)..So in order to get the info from the next line u should make a table with info from i+1 line... I will try to think of something (/me goes to start lua scripting again).

[jofori89]

Anyone know where is bug in this lua file (wind move FX)?

-- Aegisub Automation script
include("karaskel.lua")
script_name = "wind move"
script_description = "Wind move effect"
script_author = "Gormel"

function wind_move(subs, config)

aegisub.progress.task("Getting header data...")
local meta, styles = karaskel.collect_head(subs)

aegisub.progress.task("Applying effect...")
local i, ai, maxi, maxai = 1, 1, #subs, #subs

	while i <= maxi do
aegisub.progress.task(string.format("Applying effect (%d/%d)...", ai, maxai))
aegisub.progress.set((ai-1)/maxai*100)
	  
local l = subs[i]
		if l.class == "dialogue" and not l.comment then
			karaskel.preproc_line(subs, meta, styles, l)
			wind_move(line)
			maxi = maxi - 1
			subs.delete(i)
		else
		i = i + 1
		end
		ai = ai + 1
	end
	aegisub.progress.task("Finished!")
	aegisub.progress.set(100)
end

function wind_move(line)

   -- local wind_move = ""
   local rotz = -math.random(1,4)*2
   local l = table.copy(line)
   
   wind_offset = l.duration/(line.kara.n)

   for r = 1, line.kara.n do
      wind_move = wind_move .. string.format("\\t(%d,%d,\\frz%d\\fry%d)",wind_offset*(r-1),wind_offset*r ,rotz,rotz*3+10)
      if rotz < 0 then
         rotz = 0   
      else
         rotz = -math.random(1,3)*3
      end
   end
   return wind_move
end

-- Main function to do the templating
function filter_apply_templates(subs, config)
	aegisub.progress.task("Collecting header data...")
	local meta, styles = karaskel.collect_head(subs, true)
	
	aegisub.progress.task("Parsing templates...")
	local templates = wind_move(subs, config)
	
	aegisub.progress.task("Applying templates...")
	wind_move(line)
end

function macro_apply_templates(subs, sel)
	filter_apply_templates(subs, {ismacro=true, sel=sel})
	aegisub.set_undo_point("Wind")
end

	-- check if this file has templates in it, don't allow running the macro if it hasn't
	local num_dia = 0
	for i = 1, #subs do
		local l = subs[i]
		if l.class == "dialogue" then
			num_dia = num_dia + 1
			-- test if the line is a template
			if (string.headtail(l.effect)):lower() == "Wind" then
				return true
			end
			-- don't try forever, this has to be fast
			if num_dia > 50 then
				return false
			end
		end
	end
	return false
end

aegisub.register_macro("Apply Wind move", "Apply Wind move", macro_apply_templates, macro_can_template)
aegisub.register_filter("wind move", "", 5000, wind_move)

What error does aegisub return?

[jofori89]

Lua reported a runtime error:
[string "utils-auto4.lua"]:33: bad argument #1 to 'pairs' (table expected, got userdata)

This is info did returned

[jfs]

You have two functions named "wind_move", the second one overrides the first, so the first is never used.
You then register "wind_move" as an export filter, when that filter is run it will obviously call the second wind_move function, which it was bound to, and pass a subtitles object as the first parameter. The second wind_move function assumes the first parameter is a subtitle line table and performs a table.copy() on it, and this fails because the subtitles object is not a table.

Solution: Rename one of those functions.

Also, please indent your code properly. It's impossible to follow currently when the indentation is all over the place.

It did made by After Effect (AFX) but i can give you some codelines to make a FX similar it in auto4. This is the code i create for H2O ED
\move(!line.left+syl.left!, !$lmiddle+5!, !line.left+syl.right!, !$lmiddle+5!)\t(\frz-!90*(math.floor(syl.duration/300)+1)!) moving and turning, try create a code by yourself

[jnazh]

thanks man ... thank u very much bro

[salty]

also, check the AFX thread. crash made a tutorial on how to do that move effect with pichu's krk script. i think that kara might have been based from crash's, and kara maker just added twists of its own.
