problem is so big and obvious that there would have been so many<br>
reports. So it's obvious that it's a problem with my system alone. <br></blockquote><div><br></div><div style="font-size:small" class="gmail_default">Maybe, but not necessarily! You built from the GIT repository which has some BIG changes in that were not in the January 31 build which almost everyone else is using. There are 6 library updates AND the deadlock problem that gg fixed impacted a lot of routines. So it is not a waste of time for me to test anyway, because I have to have something more interesting to aim for and am in the process of trying to get a "single frame" failure that Pierre incurs too (issue #125). Also, I will try to get GG to build a ubuntu16 version later today so IgorB can verify that this newest version does not slow down - which will help isolate the problem to just your computer. Unfortunately for IgorB, the drag handles have not been modified to more closely fit his expectations because GG thinks that the consistency of how they work and are coded is too important to change, but I am still working on it/him!<br></div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">OpenGL is used in playback when it can, but not always. If a plugin or transition has code of "handle OpenGL", it usually will use that, but not all plugins/transitions do, which means it will use software rendering instead and be slow.</div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">The demo you emailed earlier where the sound continues to play but the video stops shows the problem that occurs when the program is short of CPU -- this is where "Play every frame" can be turned off to help.</div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">Also, it does not look like you have "colors" enabled and that is good -- having to draw the colors is time-consuming (but apparently "Charlie" can handle it). Background rendering, which I think is misnamed, may be a good way handle larger media and I am trying to understand it better and will put a demo out later if I can. Glen MacArthur uses it a lot on one of his slower computers. You have to be sure to set it up in settings->preferences, Interface tab, and especially create the background rendering directory because it creates many, many brender files - one for each frame.</div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">gg/phyllis<br></div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default"><br></div></div></div>
