Resize Track
by Andrea paz 04 Jun '20

04 Jun '20

During some tests to change the resolution of a track (RMB + "resize track"), I put very large numbers for W and H (about 18000). Since they are not handled by CinGG (obviously) I had a Crash. I thought, could you have a warning when the numbers entered exceed 8k so as not to crash? (I promise: this is the last post for today...) :-)

Curiosity
by Andrea paz 04 Jun '20

04 Jun '20

In wikipedia, in the entry on Cinelerra, there are news from Adam Williams about the releases of his Cinelerra-HV: "Cannot drag and drop edit clips anymore, feature removed here and future versions." (2010-10-17) and "Text to movie". Allows one to turn a script into an instant movie with live updating and seeking." (2011-08-06) Does the first one mean that originally Cin had Drag&Drop editing? Modes that GG has recently introduced? The second news, I don't know what it's about; does anyone know what it means?

May monthly builds ready for download/install
by Phyllis Smith 03 Jun '20

03 Jun '20

The latest distro built versions are on the website for tars and pkgs. We did do 1 more last Ubuntu19 static tar but hopefully users will have upgraded to Ubuntu20 by next month. A text copy of the Release Notes, which are also on the website, are listed below for May. We tested the package version for Ubuntu 20 and Mint 19.3 but please let us know of any problems. **************************************************************** Cinelerra-GG (Version Infinity) Release Notes for 05/01/2020-05/31/2020 *First, some notable musings:* - *50th monthly release* of Cin5.1/CinGG providing user builds for a number of distros. - The *bug tracking system* starting on 2018-11-26 with issue # 1 is working well with a *total of 442* feature requests or problems to date. There are about 170 open issues and 240 closed ones. - The partially *Spanish translated manual by Sergio* has been updated and is at: https://cinelerra-gg.org/download/CinelerraGG_Manual_Spanish.pdf - *Wikipedia French *version is being updated by *MatN and Pierre*. - A very detailed description of *how to make a video which includes TIFF images converted* from raw Nikon DSLR images with Raw Therapee has been written by *Richard*. It is at: https://cinelerra-gg.org/media/demos/Cinelerra_Transparency_Setup.pdf 1. Implementation of new *Audio features* (Glen + others request) include: #1 request - Audio track height button now available that is separate from the video track height. #2 request – difficulty in coming up with a way to implement combining stereo tracks together. 2. Upgraded the build system distros to the latest updates available during May. And updated Arch and Tumbleweed on the 30th so it is in synch as much as possible. Because Leap opensuse 42.3 reached End of Life in June of 2019, no more builds will be done for that distro. 3. *Usability Improvements*: The last of the Videoscope improvements to include an additional setting request of “ *Refresh on Release”* for dragging on the Compositor and Viewer and the TimeBar on the timeline (Pierre suggested feature). *Rotate* plugin fixes to include making the + rotate point dependent on the track size, increasing the scaling when use the mouse wheel over the rotate dial, and fixing a bug in OpenGL for a yuv color model (RafaMar BT # 422). Capability added to *individually increase/decrease vertical size* of any track in the patchbay. The tumbler icons for most themes were created new (provided by IgorBeg). Spanish modifications for translation and tips have been added (provided by RafaMar). Plugin expanders and minor French translations added (provided by Pierre). An enhancement to the Dump file was made to show what is in cache to help in analysis. 4. Transitions at the beginning of a video track were not showing up when the video driver was OpenGL, but this has now been fixed. A circular situation was occurring when 1 video track using a shared track was pointing at a track that was pointing back at the other track. With the correction when this occurs an error message is generated similar to “circular references, track #, plugin_set 0, plugin 0” (RafaMar BT #423). Corrected a nested asset audio bug when using clips from the same initial track (Fary54 BT # 425). Boxblur plugin had an integer round off problem in the “power” parameter fixed (RafaMar BT #429). Fixes were added to avoid memory leaks and other problems as noted by a Valgrind report to include fixes for loss bytes problem in edl.C and performanceprefs.C (provided by Andrea). A booby lock problem in keyframe was found and corrected. Added a startup lock for LV2 plugins to avoid problems. Vicon thread crash has been fixed. This has been happening for awhile but inability to determine the cause resulted in a delayed fix (Andrea noted this crash, provided number dumps/tests). Vicons are used in the Resources Window as a thumbnail picture of the media and the problem seemed to be only when using the “mouse over” feature which solo-ed the vicon. In using OpenEDL on a nested asset in level 1, when the length is modified the change was not being propagated to level 0. This is now fixed (Fary54 BT #430). Fixed audio/video module in the nested command setup to solve a problem when loading several nested assets resulted in a corrupt audio edit (Fary54 BT #425). For the Speed auto, when changing the speed by means of a numerical value, the speed change was incorrect but is now fixed (RafaMar BT # 436). Another problem with Speed auto when set the value to 20 instead of 2 was located and fixed. Perspective effect was showing a single un-changed frame when used to rotate an image horizontally but a mod was created to handle that divide by 0 case and show no image instead (MatN BT #432). The thumbnails on the timeline were not being updated when using OpenEDL and making edits in layer 1 and then reverted back to level 0. This is now fixed. When you drag & drop a nested clip from Media to a new MediaUserBin it now shows up correctly in the Resource window (IgorBeg BT # 427). Presets for plugins using the Attach Effects menu was crashing but is now fixed (DeJay / MatN). The Title of the program window was not being updated when loading a project XML file using the Load file pulldown so that is working right now (IgorBeg BT #431). A patch was made to correctly propagate gang autos.

Like long ago, I crash when I try to use openEDL on a clip. I attach the dump.

CONTEST!

If you have a video you're particularly proud of (it's better if it shows inside it how it was made in CinGG, but it's not decisive), you can tell about it on the Forum or in the Mailing List. It could be published on the first page of our Youtube channel.

Question about proxies and wide gamut screen ICC profile
by Dragonfly 25 May '20

25 May '20

Hello, I may have missed it in the manual, and I haven't done it in a long time. So I am looking for recommendations. What proxies do you recommend if the mixed footage include .MTS or .mov files compressed with H.264/MPEG-4 AVC; 1080 24p to 60p. My main computer is older (AMD Phenom II 4 965 3.4Ghz and NVDIA GTS 250 1G, Sata drives) and in the past I had to convert to dnxhd proxy. Is it still the same process? Also if I am using a generic ICC file for my wide gamut screen that was offered in Ubuntu studio. Should I switch to sRGB profile since final product will be streamed in Vimeo and YouTube? Thankyou Tanya

Hi, Rafa. I wanted to add Tutordidi's playlist to our Youtube channel; but I don't know how to do it. How did you put, for instance, Chipper's video? Do we have to upload every video in our channel or is the link enough? The link to the Tutordidi channel is as follows: https://www.youtube.com/watch?v=Nv2a4GmPMdY&list=PLfKHh1b8s3Y1v2umY4FYukDfa…

Fwd: Re: [Libav-user] NV12->RGB24 vs YUV420P->RGB24

Is there anything relevant for Cin's internal working (in case when hw decoder is used)? ---------- Пересланное сообщение ---------- Тема: Re: [Libav-user] NV12->RGB24 vs YUV420P->RGB24 Дата: Четверг 21 мая 2020 Отправитель: Alex Agranovsky <alex(a)sighthound.com> Получатель: libav-user(a)ffmpeg.org Going NV12->YUV420P->RGB24 instead of NV12->RGB24 made a material difference, thanks!

Tracking (or tracer?) control points
by preobraz＠gmail.com 21 May '20

21 May '20

Hi all! In the video (watch from 1:13): https://www.youtube.com/watch?v=3kzKhedIX1o shows how a clip is inserted into a chromakey area. I looked at the Tracer effect in Cinelerra-gg, but I still did not understand whether it was possible to perform a similar task with it. If there are no such instruments in Cinelerra-gg - maybe try to adapt the Motion effect to the task? I think solving this issue will add cinelerra-gg even more professionalism. For information: in Adobe After Effects,Screen Replacement & Motion Tracking solves this problem. Example: https://www.youtube.com/watch?v=JJmvrNmso5Y -- Ugin
