Multiple scrolling title effects problem

[miko@…]

When using more than one title effect on a video track, all but the first one do
not produce any output when their motion type is set to one of "Top to bottom",
"Right to left" or "Left to right". It works correctly when set to "No motion"
or to "Bottom to top". Note that the first title effect works for all motion
types. The sentence "do not produce any output" means it behaves like there was
only the first title effect, and the other were absent or switched off.

This is confirmed for vanilla 1.1.9 and cvs versions, compiled from sources on
RedHat 9.0 with all standard packages updated, and with additional packages
installed by apt-get from popular sources.

How to reproduce:
Start cinelerra (by default 2 video and 2 audio tracks are created), select some
range (eg. 5 seconds), attach a title effect on it, then select another range
(e.g. next adjacent 5 sec), attach another title effect. For both effect select
motion type to e.g. "Right to left" and then see the result in composer window.
Change motion type to "Bottom to top" or "No motion" and compare the result.

Patch fixing scrolling text in title effect plugin

You sure this helps you?

I cannot find any difference and i still have the same problem ...

when you are not using keyframes, motion start is calculated for frame 0, but i
expect it to start at first frame of plugin.

Patch for titler motion

[andraz.tori1@…]

please test my patch and tell me if it works for you as expected...

the trick is at the end.. using get_source_start when previous keyframe is 0

[andraz.tori1@…]

i just noticed that the second part of my patch already exists in heroine's
tree... it checks wheater previous keyframe exists

however third and fourth part of your patch are broken. you should leave
last_keyframe_position and not get_source_start ...
in your case they have the same effect, but not generally...

after that you should send your patch to heroine... and i am commiting my patch
to CVS

have you sent the patch to heroine?
