hey i found that problem as u said ,
the main problem its we need to add that 2 value and i try on default gui 1st
and the result is
the m12 should be 0 and frz should be false and i put manualy on running text presets
{"on":true,"bri":20,"transition":7,"mainseg":0,"seg":[{"id":0,"start":0,"stop":8,"startY":0,"stopY":8,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"n":"mytext running here","col":[[255,0,255],[0,0,0],[0,0,0]],"fx":122,"sx":120,"ix":128,"pal":11,"c1":0,"c2":128,"c3":16,"sel":true,"rev":false,"mi":false,"rY":false,"mY":false,"tp":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0}]}
1D effects its unavailable to access after changing mode to running text then i force m12 to pixel and frz i force to 0
thats now running smooth between 2 transitions thanks @ALDIY 2 thumb up
