David, For Ubuntu 19, timeline speed seemed to be slow and LFOM informed us of this in the Cinelerra-gg.org Forum. He tested mods we added and said that these helped a lot. These speed improvements for line drawing on the timeline use Bresenham's line algorithm. It is very difficult to diagnose a problem like "it seems to run slow" because it does not run slow for us on a laptop and desktop with the Fedora operating system. If you can provide additional data, such as which Operating System you use or you want us to check for slowness on a specific small piece of media (upload somewhere or email to [email protected] if you want it to remain private). Or if you would like to check the improvements using Brensenham, we can create a temporary static tar for your operating system (all new builds will be provided at the end of the month on April 30th). Any further specific information you can provide may help us solve a problem so we appreciate it. Phyllis/gg On Fri, Apr 24, 2020 at 10:44 AM david <[email protected]> wrote:
Hi all.
I have been trying some video editing with Cinelerra. It seems a very powerfull program but I am surprised of the clunkyness of timeline when I move video pieces, or select them for moving. My tests are very humble. Only two pieces of video of no more than 20 seconds. It is very frustrating to be precise enough when moving parts. Is it normal? Perhaps some bug with my media or configuration? Video composition in previewer is fast and very good, but not commented simple operations.
Comparing other options, like Olive editor, in which working with parts is very fast and precise I ask myself if there is space for Cinelerra optimizations in this matter.
Thank you very much for your work :)
Greets.
