Cinelerra does NOT have an effect for changing the speed of individual clips, this today makes Cinelerra a little off the hook for professional applications. The ideal and normal thing today is to have an effect capable of manipulating the speed of a single clip and automatically also change the duration of the audio associated with this clip while maintaining the pitch (timestretch). Being an ignorant of programming I thought that this would be easy to implement, since open source Audacity has an excellent Timestretch effect, and I thought that the code could be reused and adapted to Cinelerra.
I had problems with this too. being able to speed-change armed video and audio racks at the same time would be a time saver.
Another thing that confuses new users a lot is the default settings for the sliders on the camera and projector wizards. These are set to only 100 px in both X and Y. Is it very difficult to define these X and Y values to the px of the project? for example if I am working on a 1920x1080 project the maximum and minimum of X should be -1920 +1920 and in Y -1080 +1080. Although I still think that the ideal would be to work with percentages, where 0 is the default point, -100% the clip completely off the screen from the left or from below, and 100% clip was from the right or up. Perhaps this point is the most irrelevant when it is discovered that this can be configured in the values below the timeline and even manipulated from the screen itself, the slider is very secondary. If I knew how to program apart from the aforementioned, there are two things I would do with these assistants, include the option to rotate and some axes on the screen so that when you rest your mouse on them and move, you can only do it from the selected axis. But I understand that these things a programmer will only do when he is bored at home, because they are not important either.
Yes, the 100 +/- values have bitten me too. +1 for changing that to the values set in the Settings->Format. Percentages would be fine, provided the resolution is sufficient that there still can be pixel-accurate positioning at 8K . MatN
