Hi.
I would like to merge avi secuences dissolving preview to the next one instead of cutting. Is there any easy way or any filter to do that in VD?
Thank you in advance. |

None that I knew of. But others may
.
However, did you try the Zoom-Filter? You could zoom in and out, or try the Fade-Filter.

Thank you, Cyberman, but what I want is not to black fade in or out (that I already use in transitions I require it). The transition effect I'm looking for is simply dissolve the end of a secuence segment to the beggining of an appended one.
Zoom filter doesn't solve that either; it is not the effect I want to...
I guess I could cut end and begginig of that segments, export them to image secuences, treat them in a graphic suite and then import the result to VD appending it to the original ones... but I'm sooooo lazy (ufff)
Anyone know some EASIER WAY to do that? |

Try this one: http://www.avisynth.org/index.php?page=Dissolve
Itīs not VirtualDub but Avisynth. Since I donīt really know that program, I canīt tell if itīs any good. AFAIK itīs something similar to VD, isnīt it?

Another crafty method to do what I want to could work using David Roden's 'overlay' filter. The thing would be as it follows (although I haven't tested it very deeply yet):
0. First of all, we have the two avi segments we want to join with a dissolving transition.
1. We open the one which will be placed in second term.
2. Cut the part that won't be in the transition leaving the one that will appear in the end of the first segment.
3. Export all that frames to a TGA image sequence (file/save image sequence).
4. Close the avi segment WIHOUT SAVING.
5. Now here it comes the real crafty part. We're going to elaborate our dissolving effect from or TGA image sequence using a graphic manipulation program (such as Gimp). Now we'll apply a different level of transparency to each frame/image in our sequence. In example, if we've got 25 frames in our transition sequence we will apply an increment of 4% in opacy beggining from the first frame to obtain a homogeneus effect.
6. Once we've finished retouching our images we go back to VirtualDub and open de first segment avi.
7. Now we'll apply the 'overlay' filter to make our long desired transition effect. We select the filter and load our modified image sequence (selecting the file named as *001.tga). Choose the starting frame (count the number of frames in our avi segment and substract the number of images in the squence) and set the position parameters for a perfect image fit.
8. Save the changes in an avi file and close.
9. Open the second avi segment and cut the part wich is contained in the transition frames of our modified avi.
10. Save as avi file.
11. Now, we can join our two segment and test the effect in action... and who knows, maybe it even works fine ;-)

That looks very interesting -and not very hard to apply-, I'll try it and tell.
Thanks :-) |
