Summary0000564: When something extends the clip in the timeline, the applied effect is not extended
DescriptionI get bitten by this quite often, and was unsure if it was me or something within Cinelerra. It is pretty convenient to edit in a single video track, at least visually. But the problem especially with dissolving and other effects that extend the duration of a clip is that the effect on the clip is truncated on the solve point.
Steps To Reproduce1. Create a single video track, with 2 videos after each other. Apply a transition such as dissolve on it.
2. Apply an effect such as Motion 5.1, notice how in the dissolve phase the effect is not applied anymore, because it is limited to the cut point.
TagsNo tags attached.

@skinkie -- BUT it should be fixed to work better for Motion51. Using a transition with Motion51 was most likely not considered when this plugin was written. It is time to fix this as in testing Motion and Motion2Point, they are able to handle this.

I have reproduced what you see, but I do not think this is a bug but rather Motion51 actually working on tracking. Now I am testing more plugins to see if anymore have a transition issue.

It is that in the case of the effect of Motion is not an error, it makes a reading of the clip pixels and in the transition there is a mixture that escapes the effect.
Then when you work with melts, if Motion is required in a clip, this is better that it is complete on a track covering the entire clip.
What to work on a single track is not ideal for advanced issues, it is something that in the professional field is considered an amateur video. You do not have to skimp on tracks in advanced editions, they are precisely for this, and Cinelerra is designed to work with multiple tracks to carry out these techniques correctly.

This is exactly the workaround I use ;) But can we please solve the actual bug here :)

Ok, now I understand better what happens.
It is true that some effects have problems with transitions.
In these cases, especially with the Motion, it is best to use two tracks and make a cross-cast or in this way also, look at the following images, in the first one I have made a cross-cast with the opacity line (Fade Line)
In this use two tracks but the transition I make it up, in both cases the problem of the effect is resolved, because this can not read about the transition, but on the clip. In both cases the result is the same.

@PhillisSmith you are now extending the effect. I do something similar to @RafaMar I apply the plugin to the individual clips, and do not extend the effect.

Maybe I am doing something different, but I can not reproduce the problem. See:

@RafaMar the problem is specifically what happens at the dissolve. Hence I would expect that the left effect happens until the end of the clip, including the dissolve. When the motion effect is used I see a jump inside the dissolve, as if the plugin gets detached.

I do not understand very well what the error is, so my response can be totally erroneous.
I understand that you want to insert the same effect to all clips on a track.
The duration of the effects when inserted is subject to where this is released, unless there is a selection. If there is selection you also have to let go in the selection. What will cover the effect is shown with a white box.
I have made a video with a color effect so that the box that delimits the insertion is visible, and that it depends a lot on where the effect is released when we dragged it.
If we insert it with the right button wizard, it is best to select the section where you want to insert it. I have also made a video so that this is seen.
