Subtitles blink for a moment.
 

{0}{100}
{101}{200}There the subtitles blink for a moment, but this is OK.

{0}{100}
{100}{200}There the subtitles blink for a moment too.
Is it possible to make the subtitles don't blink in this example.

For example:
{2251}{2308}TERMINATOR 3
{2308}{2418}TERMINATOR 3|RISE OF THE MACHINES

First show TERMINATOR 3, then the TERMINATOR 3 must stay, then show RISE OF THE MACHINES.

It will be good if subtitles will show more smoothly, without blink, if this is possible to make.

This appears generaly on lines in wich you have 1 or 0 difference between the last frame of the first line ant the first frame of the second line. Try to make that difference 5 and it should go smoother.
Example 2 is not correct. It should write TERMINATOR 3, then blink, and after that to write , using two lines, TERMINATOR 3 and RISE OF THE MACHINES right under. The line including ter3 will move up.

First I apology, because my english is not very good.
I agree with you.
But I just suggest this because I know this is not posible yet.
It writes TERMINATOR 3, then blink, and after that write TERMINATOR 3|RISE OF THE MACHINES in two lines, but if it is possible to go without that blink in some new versions, or not possible at all.
