How to make karaoke style text

[profquad]

Hi, I'm using my own slightly modded version of text overlay for color, but I'm wondering how to add a horizontal wipe between two text strings of different colors, so I can add a wipe position envelope and get that karaoke effect.

Here's the text overlay code I use:

// Text Colorful
#text=""; // set to string to override
font="Arial";

//@param1:size 'text height' 0.05 0.001 0.2 0.1 0.001
//@param2:ypos 'y position' 0.95 0 1 0.5 0.01
//@param3:xpos 'x position' 0 0 1 0.5 0.01
//@param4:border 'border' 0 0 1 0.5 0.01
//@param6:fga 'text alpha' 1.0 0 1 0.5 0.01
//@param7:bgc 'bg bright' 0.75 0 1 0.5 0.01
//@param8:bga 'bg alpha' 0.5 0 1 0.5 0.01
//@param9:r 'R' 255 0 255 128 1
//@param10:g 'G' 255 0 255 128 1
//@param11:b 'B' 255 0 255 128 1
//@param12:ignoreinput 'ignore input' 0 0 1 0.5 1

input = ignoreinput ? -2:0;
project_wh_valid===0 ? input_info(input,project_w,project_h);
gfx_a2=0;
gfx_blit(input,1);
gfx_setfont(size*project_h,font);
strcmp(#text,"")==0 ? input_get_name(-1,#text);
gfx_str_measure(#text,txtw,txth);
yt = (project_h- txth*(1+border*2))*ypos;
gfx_set(bgc,bgc,bgc,bga);
gfx_fillrect(0, yt, project_w, txth*(1+border*2));
gfx_set(r/255, g/255, b/255, fga);
gfx_str_draw(#text,xpos * (project_w-txtw),yt+txth*border);

I tried adding some lines from "Horizontal wipe" but I'm just a hack and don't know how to make it apply to strings instead of the full image.

Just in case you're not aware, HeDa Notes Reader script works great for queuing lyrics, ableit without any fancy fx. It uses empty items for the text and the item position is used for alignment.

I would generate the same line of text twice on 2 items in different tracks, one wihtout outline the other with. Then I would use the horizontal wipe transition to "advance in the text and repeat the process for each text page. BTW I made a text overlay that makes ajustable high quality outline.

Haven't gone VIP with heda yet. Seems like the right idea, but still curious how to add a wipe to text only. I have background video, and the Horizontal wipe effect wipes that out too. Tried every combo of "left input" and "right input", couldn't get it to just wipe the text.
Is there a good coding resource? I try just reading the definitions but mostly just change things, see what happens.

ah this always happens right after i post lol, just moved horizontal wipe beneath text overlay in the fx chain, it works

Notes Reader's not VIP.

2 instances of the same text with different outline styles on 2 distinct tracks. Then use an horizontal wipe with envelope.

Can you show it to me in an example project? I'm really not good at this.

Thank you @papagirafe

I suggest you take some time to study this tutorial video:

but nevertheless, it seems a mystery for many so here is a sample project:
