Scrolling text / Flickering / Expression

[lemakigote]

Hello everyone,

i found a formula on the web for avoiding at max the flickering effect on scrolling title for non-interlaleced video

rate = 2; //value in px/sec.

value - [0,rate*timeToFrames(time)]

its working pretty good for vertical movement but i would like to use it for an horizontal movement ( Legals on bottom of frame that have to roll from right to left on some commercials )

i tryed to use this formula but it's working only on the Y axis.

can someone help me on this?

have you a better solution / formula for horizontal movement without flickering?

sorry for my english, iam french

thx in advance

I guess this will work both for X and Y axis:

rate = 2; //value in px/sec.
value - [rate*timeToFrames(time), rate*timeToFrames(time)];

Values inside brackets is an array of values [x, y] , that are deducted from the property value.

Oh, sorry, I misunderstood your question.

Here is the expression for horizontal movement:

rate = 2; //value in px/sec. 
value - [rate*timeToFrames(time), 0]; 

Value inside square brackets represet position as [ x, y ].
