They do the same thing, Hi Dan, ...the problem is: from a technical viewpoint, they don't do the same thing, because they are pulling video data out of two sources wheras effects pull out of one source (the predecessor in the effects chain). While I agree with you that it would be much more intuitive to have transitions behave like effects this would imply a generalisation of the effects infrastructure and there are good chances this would mean touching and adapting every existing effect as well.

I believe that this approach was used in the past by Adobe Premiere. I think they were known as A and B tracks, reminicent of the the old A and B rolls when editing was done on film.

Re: [CinCVS] Effects order.
But in recent Premiere versions you can still use transitions between two different tracks (but you are not limited to A and B tracks, of course, and you can blend between edits aswell...)

Hello Andraž, Hello Marcin, quite often, I got struck by this behaviour. I consider it -- not quite a bug, but rather a shortcomming of the design, i.e. the way transitions are implemented and controlled in cinelerra. It is a shortcoming in the design, and it has been discussed before. The problem is actually not the effect order, but the fact that effects are applied to the timeline only. The transition effects peeks into parts of the source video that is beyond the edit, and not on the time- line. Whether you apply the effects before or after the transition, it will not fix this problem. Say clip A has a brightness correction and clip B has a colour correction, applied as effects, and a crossfade between them: (CF) A BBB brightness correctioncolour correction At the clip point, A starts fading away, but suddenly loses the brightness correction. B's colour correction slams in at 100% before B is visible, and is applied to the mix of A and B. What Marcin and Hermann want, is the brightness correction to be applied _only_ to A _throughout_ the crossfade, and the colour correction to be applied _only_ to B, also during the crossfade. Some of us suggested that we should implement this, with extra markings on the timeline to indicate when effects would bleed into transitions. However, it was deemed too complex, and dropped. You may get almost the desired result by crossfading the effects, using keyframes, if the transition is a crossfade. Otherwise, you have to use two tracks. -- Herman Robak ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Re: [CinCVS] Effects order.
Hi Andraz Of cource, i meant edit. That is exactly what i did. But it is annoying if you have more than one edit (e.g 100). And requires reencoding. On the other hand this also means that transistions which have overlap are not compatible with effects which is a major cinelerra concept-bug. It should be somehow possible to apply the effect to edit before doing transition. the best Marcin Kostur ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
[CinCVS] Effects order.
Dear Users, There is the next problem i have with snv 2.0: Suppose i have two video tracks which i would like to join with a transition. Additionally i need to corret colors (e.g. histogram) on those tracks, but the color correction depends on the shot - (e.g one was couldy one sunny). What should i do? If i apply histogram to each track, then the transition will use uncorrected part in overlapping moment (is it a bug?). If I apply histogram to the whole video then the control over histogram parameters becomes very difficult (invisible keyframe settings). Stacking tracks is also very cumbersome (suppose i have 20 of them ;-) The way i did it was correct a track and render but it introduced unecessary DV-reencoding. Do you have any tips?
