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 <a href="mailto:phylsmith2017@gmail.com">phylsmith2017@gmail.com</a> 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).</p><p style="margin-bottom:0in;font-weight:normal;line-height:100%;background:transparent none repeat scroll 0% 0%">Any further specific information you can provide may help us solve a problem so we appreciate it.

<br>
I have been trying some video editing with Cinelerra. It seems a very powerfull<br>
program but I am surprised of the clunkyness of timeline when I move video<br>
pieces, or select them for moving. My tests are very humble. Only two pieces of<br>
video of no more than 20 seconds. It is very frustrating to be precise enough<br>
when moving parts. Is it normal? Perhaps some bug with my media or<br>
configuration? Video composition in previewer is fast and very good, but not<br>
commented simple operations.<br>
<br>
Comparing other options, like Olive editor, in which working with parts is very<br>
fast and precise I ask myself if there is space for Cinelerra optimizations in<br>
this matter.<br>
<br>
Thank you very much for your work :)<br>
