<p>Camille,</p>
<p>I vaguely remember such a similar case, but it was a very long
time ago, hence this old work around with the fade line.<br>
However, after trying to reproduce this problem currently, I
have not succeeded. It runs fine every time, just like Phyllis,
without the problem you describe. <br>
<br>
My question to you. Which Cinelerra version are you using? Can
you show a screenshot or short video of your timeline scenario
and what parameters are set on your end so we can better
reproduce the error? Maybe we missed a setting you are doing and
with an exact match of the setting we can reproduce this issue.
Thanks in advance.</p>

<div class="gmail_default" style="font-size:small">Honestly, I
never see a flash and I have tried several variations based
on your description with the "fade in text parameter" being
the easiest. I did do a recording of it and planned to show
that but the recording does not do a precise capture job so
you can not tell it is working correctly. There was no
flash when playing at normal speed and then I tried single
stepping and still no flash.</div>

attaching a screenshot of how to set this up easily with the

about 3 seconds of nothing and added a Title plugin making
sure to set the Fade parameter on the Title menu to 3.0
seconds (I use the reset button first to make sure there are
no leftover weird settings).<br>

<div>Hi Sam, thanks for your reply, yes the fade line
works, however it's not suitable for what I want to do,
I want to fade many snippets of text and transparent
PNGs on the same track, with always the same video
transition filter set to the same duration. Otherwise
it's too complicated to combine them on two tracks and
adjust manually the fade curve for each. I posted the
example of fade in text parameter as it's simpler than
transition do explain, but it produces the same "black
flash" bug.<br>
