Resources Window -> Clips (make the program window less responsive)
Hi, I noticed that when I create a few clips (more than 10 clips), with "ToClip" function, Cinelerra-GG is less responsive in some things. I remember that "ToClip" function puts the clip in the Clip Resources Bin window. When in the Clip Resources Bin window there are more than 10 clips (in my case 42 clips), Arm or Disarm a track in the Program Window, using the Mouse in the Patchbay, takes about 2 seconds; BUT, instead of using the mouse, I use the Tab key (shortcut) it is immediate. Mmh,... very strange. Or if, after placing the Insertion Point between two edits in the Video track, I add a default Dissolve transition using "Shift+U" shortcut, it takes about 2 seconds; same thing also for Detach that transition using the mouse. If I delete all the clips in the Clip Resources window everything goes fast. Below my settings to save system resources: - ThePreview Mode in the Resources Window is "No Play". - In Settings-> Preferences, under the Appearance tab, I have unchecked "Use thumbnails in resource window". Any ideas? Thank you. IgorB
IgorB, I am trying to duplicate your results but have not yet.. On Sat, Jul 25, 2026 at 2:11 AM Igor BEGHETTO via Cin < cin@lists.cinelerra-gg.org> wrote:

Thank you, Phyllis. Maybe it is due to Charlie, my very old laptop (from the 2010s). Il 26/07/2026 03:23, Phyllis Smith via Cin ha scritto:

I didn't notice any slowdowns when creating 15 clips. But my system has 32 GB of RAM. A while back, I noticed improvements in CinGG's responsiveness by setting: 1- Settings --> preferences --> performance --> Cache size (MB): 4096 2- Settings --> preferences --> performance --> Seconds to preroll renders: 1.0000 This probably isn't related to your problem, but it might help to set these parameters optimally for your “Charlie.”
IgorB, Like Andrea, I do not get any slow downs - either from using the mouse in the patchbay to disarm any of the video/audio tracks or from using Shift-U to add the Dissolve transition. I created 50 clips and tested on my laptop with Fedora AND on Ubuntu 16 desktop environment with the alternative shortcuts version. Also varied the cache size in Settings to way low and way high. When I ran "top" on another window to watch my memory usage, I do see MiB Mem: "used" go up on the creation of another clip, but only by about 2. Note that "top" also shows MiB Swap: which in my case is always at 0.0 used. The only things I can think of that might be the problem are: 1. Possibly you are out of Memory and Swapping -- you can check this by running "top" from another window to check. Even though the shortcut "tab" is working correctly, it executes a different set of program code than using the mouse. 2. Or could it be that the Ubuntu operating system on Charlie is fielding the mouse differently when low on memory? whereas Cinelerra directly fields the "tab" key?

Thank you so much, Andrea_paz and Phyllis, for all the tests you have done. Andrea, I tried using your settings but, unfortunately, nothing has changed. I think it depends by my Project. When/if you have time,... I add a compressed file where you find my Project. There are no media but the Project can be opened. I am sorry, for file upload problem on the Mailing List, this is the link to: www.visi1.org\CGI_download\ilBagnoPadronale_byCin_720x576-16d9-25fps_m.tar.gz I will go to try with Phyllis' suggestion: run with CIN_CONFIG=/tmp/bcast1 x.AppImage Off Topic: I am seeing that your emails are being sent to me from the mailing list. AND you are sending me a copy directly from your email to mine. You are great! Thanks, but it is no longer needed, I hope. ;-) Il 26/07/2026 21:50, Phyllis Smith via Cin ha scritto:

Andrea, thank you so much for your tests. Probably, your computer's performance is so high that you can't see this latency I can see. In my laptop, switching "Charlie" governor from Powersave to Performance, it is more responsive but not much. My Laptop has 8GB of RAM. Once the Project is loaded into Cinelerra-GG, Top program says: - for Cin program: %MEM=26.1 (max peak 38) - Total Mem Used: 2500000 KiB (of 8GB) This , using "Use thumbnails in resource window" = CHECKED in Settings-> Preferences.

I tried out your project, but I don't notice any slowdowns.
How much RAM do you have? How did previous projects with multiple media files and clips perform?
using the Mouse in the Patchbay, takes about 2 seconds; BUT, instead of using the mouse, I use the Tab key (shortcut) it is immediate. Mmh,... very strange.
Igor, again like Andrea, I had no problems. But the unusual behavior as quoted above is to me the most concerning. After reviewing the xml you provided, I am wondering if it is not clips that is the cause of the problem, but rather the "Media bins" you have the same name in - for example 142_4212.JPG is in "Clips" PLUS in "z_media_bin_Photos"??

Yours, are good reflections. I tried to do as you suggest after deleting all the User Bins ("z_media_bin_*" and "z_clips_bin_*") to narrow down this singular problem. In Clips Resource window I renamed all the clips, but nothing is changed. If I delete all the clips, or I leave about twenty clips, in Clips Resource window all goes fast. Really strange. I don't want to waste any more of your time on this specific question; if you think of anything else, let me know. Thanks. Il 29/07/2026 19:05, Phyllis Smith via Cin ha scritto:
