<p />
<p />
<h3><a name="Fast_Play_effect"> </a><a name="Fast_Play_effect_"> </a> Fast Play effect: </h3>
<p />
This can be done in <a class="twikiLink" href="ReframeEffect">ReframeRT</a> from the Video Effects palette.
Select Stretch mode and enter a value greater than 1 to get accelerated playback. Note that as the clip on the timeline doesn't change in length, the video will go black before the end of the clip when all the frames have been played. You need to transition out to another video track before this point.
<p />
<h3><a name="Slow_Motion_effect"> </a><a name="Slow_Motion_effect_"> </a> Slow Motion effect: </h3>
<p />
Time compression (or slow motion) is done with <a class="twikiLink" href="ReframeEffect">reframing</a>. Cinelerra has a real-time <a class="twikiLink" href="ReframeEffect">reframe effect</a>.
<p />
<p />
The behaviour of the real-time reframe effect can be a bit confusing, it does not affect the length of the clip on the timeline, it just changes the playback speed for the duration of the effect.
<p />
<p />
At the end of the effect, the video will snap back to the "current" point of the timeline, i.e. there will be a jump.
<p />
<p />
(Think of slow-mo effects in live broadcasts; that's how Cinelerra behaves. For slow-motion this is OK; you just extend the effect to the next clip, so that the slow-motion clip will be followed by a cut-away to another scene.) 
<p />
<img src="../../../pub/TWiki/TWikiDocGraphics/tip.gif" border="0" alt="TIP" width="16" height="16" />
You can also change the frame rate of the clip if you right click on it in the <a class="twikiLink" href="Viewer">media viewer</a> and go to Info 
<p />
(If you <strong>don't</strong> hit the drop down first, you can type in a desired frame rate as well).
Cinelerra will pick the right frames out for the project frame rate, effectively doing the time-lapsing as well
