In the patchbay to the right of the default "Video 1" is a small right facing arrow. When you add an effect the patchbay right-facing arrow "expands" to make room in the timeline for the effect bar. And you will see that the right-facing arrow becomes a down arrow and the "Play track", "Arm track", etc. symbols all become visible. Once the patchbay expansion is enabled, you have to disable it to get back to the right-facing arrow space size. That is why the title will still show, because it is expanded. But you can un-expand it and then the title no longer shows. I hope this makes sense. If not, I can add pictures! gg/Phyllis

Debian packaging improvements
by Olivier Humbert 01 Jun '19

01 Jun '19

Hi Phyllis, GG and all. 3 things here, continuing on working on the Debian packaging from the 20190531 tarball. 1st : I've rewrote the debian/copyright file to be compliant with the modern standard. Please find the file attached. 2nd: I've some more information about the e2fsprogs which is recommended in the debian/control file build-depends list. It is mentioned here: https://packages.debian.org/stretch/e2fsprogs that it is an "essential" package, which mean (as far as I understand) that it'll be available in a basic Debian environment (see https://www.debian.org/doc/debian-policy/ch-binary.html#essential-packages ). Hence, it's unneeded in the build-depends list. 3rd: One of the Debian packaging tools (Lintian) told me that the source contains a file that looks like a Subversion conflict file, probably included by accident: - cinelerra/TODO.r1027 - cinelerra/TODO.r1040 That isn't a big deal at all, and I'm mentioning it here in the hope it can help to keep the sources clean. Hope that helps.

New Cinelerra-GG builds are ready for May / change notes listed at bottom
by Phyllis Smith 01 Jun '19

01 Jun '19

The tars and packages for the end of the month builds are now at: https://www.cinelerra-gg.org/download/pkgs/ https://www.cinelerra-gg.org/download/tars/ The full release notes are at: https://www.cinelerra-gg.org/download/releasenotes.pdf Updated GPU hardware acceleration document because minor changes were made on usage (temporarily at): https://www.cinelerra-gg.org/download/GPU_potential_speedup.pdf CREDIT goes to a bunch of people (you know who you are!) for contributions for themes & png-s, testing, control, setup, feedback, dumps and suggestions of more good ideas. ------------------------------------------------------------------------------------------------------------------------------------------------------ Cinelerra-GG (Version Infinity) Release Notes for 05/01/2019-05/31/2019 for builds 1. *Leap 15.1* (Sam notification) and *Debian 10.0 Buster/Testing *(AJ notification) builds now available. 2. The *Canvas lock/refresh* was completely reworked with many Mutex-s being corrected to Conditions. Although much testing was completed, there is still a possibility that a deadlock could occur under some missed situation. These could occur in the Compositor or Viewer and if using either X11 or X11-OpenGL video driver. Please report problems for analysis and possible fixes. 3. The* Masks* have had several changes implemented plus additional features to include: - *OpenGL upgraded from 1.x to 4.3 *for masking only. This will affect any operating system that has not upgraded to at least 4.3 and does not have graphics driver upgrades when using Feather. Since 4.3 was released in 2012 this was kind of a surprise until GG started updating for Cinelerra masking and found out how difficult it was to do this. The user workaround is to check the box “Disable OpenGL masking” in the Mask menu if using Feather for those computers at 1.x. - added *rotate and scale* around a pivot point to include a Focus X/Y setting - now have *names for masks* instead of just the numbers 0 through 7 and they show on compositor - the function *feather *is a logical function instead of a mathematical function so should be faster and now works correctly in OpenGL without the stairstep effect and spurious blobs appearing - rework of the mask engine and lots of cleanup done to include correcting keyframe spanning for mask auto update_params; fix for mask problem of Mask Clear generating a keyframe at position 0, and other minor bug fixes - the Mode button for *multiply and subtract alpha has been replaced with Fade slider* bar with positive and negative values - a Clear button has been added to delete All Masks for convenience - Fade and Feather sliders have a sticky at 0 making it easy to get to 0 and stay there momentarily - *Gang for fade and feather *has been added. This is a symbol to the right of those slider bars and looks like 2 links in a chain entwined. As you fade/feather one of the masks, the others will fade/feather in relation up to a point - Markers checkbox added to turn on/off the points for easier viewing - Boundary checkbox added to turn on/off the boundary so as to not interfere with your view - *radio buttons added, one for each mask*, to make it easy to quickly change from one to another and in addition the ones in use are in a different color; also a tumbler so you can use the middle mouse wheel to go from one to the other 4. *Potential bit hint for Nvidia graphics* boards computer users - try to enable/disable Vsync in ... driver's control application if you use proprietary drivers. Disable "Sync to VBlank" (option for OpenGL) in NVIDIA X Server Settings... has solved the problem! Thanks to Andrew. This might help anyone with an Nvidia card using Cinelerra and having low frames/sec. 5. *Usability Improvements* A flag in Settings→Preferences, Performance, “Use HW” device with 3 choices of none, vaapi, or vdpau has been added for using GPU instead of CPU for graphics devices that are capable of doing hardware acceleration. You may have to restart Cinelerra when you set or change this initially. When decoding during a load operation, you can make use of an .opts file to allow for specifically using hardware decode or not for a specific video file. For usage of these last 2 items, temporarily refer to https://www.cinelerra-gg.org/download/GPU_potential_speedup.pdf *Encode hardware acceleration for vaapi *(Intel graphics board) + 4 opts file (h264, hevc, mjpeg, mjpeg2) has been added. Color 3 Way plugin has had “clear” buttons added by an anonymous user/programmer. Convenient! The 16 plugins which recently had the Clear feature added, have had a *modified Clear icon* added for all the themes. This was tedious work credited to another contributor and included all variations. Olaf’s *Neophyte theme has been updated.* Especially “beautiful” is the About tab in Preferences. A *new “2019 modern” theme, Cakewalk*, has been added and is now the default for users who do not have an existing $HOME/.bcast5 file or you can switch to it. Olaf credit for both themes. *German translations* in de.po have been upgraded to fix some and include a lot more – by Olaf. Language translations in f*r.po for French* have been much improved by contributions from Olivier. The Shell Cmds feature has an additional option when doing an Add “run /path/script.sh + argvs” which allows for using $1, $2, … args by replacing them with highlighted assets in the Resource window. 6. *Bugs/Issues fixed* Build tweaks for the newest Fedora version 30 and Tags tweaks were added for debugging purposes. Fix for OpenGL Finish – OpenGL was crashing and last month’s temporary workaround is now this permanent fix. Thanks to Pierre using Mint 18.3 which illustrated the bug. CIN_FINISH has been removed because it was a workaround in effect when no other resolution was available. Title plugin fixes - missing alpha slider and color change on characters now working correctly. An error message will popup when the GPU cannot process video to pass back to the CPU. A booby trap has been fixed that occurred when you did a cancel on the outline color button in Titler. In the Titler, the Stamp timecode box was taking up too much space so had to be moved. There was a SEGV observed in vgui / cgui if closed while playing that has now been fixed. Updated ffmpeg git option in the build scripts. The line numbers always change and ordinarily it is only updated when a stable and worthy release for ffmpeg is available. Added register dumps for the system of user generated dumps to help in analysis. A SEGV was occurring because for some unknown reason there was a divide by 0 for width/height on a draw refresh. If the zero divisor condition exists, it will now change it to the number 1. OpenCV has been changed to no longer provide the SIFT/SURF algorithms due to murky patents. Make_shader routine has been reworked. A SEGV destructor error for AC3 has been fixed. There was a spurious mask drag tooltip that is now gone. Several more contributions by Olivier to repair minor problems include: - corrections to the Debian control file - the language translation xlat.sh script has been fixed - lv2_blacklist.txt additions to avoid incompatible lv2 plugins that prevent Cinelerra from starting Five more ffmpeg plugins specific to vaapi usage were commented out as contributed by John/Jacek from the Solus team. It is possible, though not probable, that they would work on some hardware. Reworked Shells Cmds to refer to the CinelerraGG_manual.pdf file and no outdated references. However these will not be in effect until your $HOME/.bcast5/Cinelerra_rc is re-created or edited. Fixed OpenGL’s transform translate (again!). Slight modification to the shell command, RenderMux.sh, in order to create a logfile when used.

Cakewalk theme
by Andrea paz 01 Jun '19

01 Jun '19

I want to be the first to congratulate for the new Cakewalk theme. At first glance it looks beautiful and fancy; you can read very well and with precision; the colors are beautiful and restful for the view; the icons are clear and beautiful. What more can I say: thank you very much.
