Index on manual in Latex (to Andrey)
by Andrea paz 13 Dec '20

13 Dec '20

Hi, Andrey. Phyllis put an Index to the CinGG manual in Latex (see git). But I can't get it to work in TexStudio. I put the following line in Configure --> Commands --> Makeindex: makeindex -s nomencl.ist -o CinelerraGG_Manual.nls CinelerraGG_Manual.nlo but if I try to build it via Tools --> Commands --> MakeIndex I get the following error: "Process started: makeindex -s nomencl.ist -o CinelerraGG_Manual.nls CinelerraGG_Manual.nlo Input index file CinelerraGG_Manual.nlo not found. Usage: makeindex [-ilqrcgLT] [-s sty] [-o ind] [-t log] [-p num] [idx0 idx1 ...] Process exited with error(s)" Actually the CinelerraGG_Manual.nlo file exists, but it is the one created for the glossary and in fact contains the glossary entries. Can you suggest a solution?

Missing plugin MOTION CV caused heavy error
by August Geyler 10 Dec '20

10 Dec '20

Hello everyone, I need your support for making the Motion CV plugin usable for me again. The background: I started working on a huge project in April this year with my team. We made heavy use of motion tracking. To achieve this we made several tests with all available motion plugins in April 2020 and decided to only use "Motion CV". Nobody knew, we chose an effect which would deleted only few month later. I couldn't even imagine something like this happening. We worked on our project for more than a month. Due to the pandemic it came to a sudden hold in May. Today we wanted to start finishing the project. When I opened the file in Cinelerra I surprisingly got the massage that the effect "Motion CV" was unknown. As I figured out, you deleted this plugin in September. I am happy to hear that the new motion plugin is much better and I will use it in the future. But now I need to render my project from April exactly in the way it was made. But this is impossible now due to the disappearance of our most used effect. I checked the syntax in the project XML. There are several differences between "Motion" and "Motion CV" so that just renaming the effect in the file did not work. I red that the old motion cv plugin is still in the libraries and downloaded it. But as I have no clue how to reinstall this into my running system I need your support. The handbook is not describing how to reinstall deleted plugins. Is it possible to reinstall the plugin by myself? Or can you provide the plugin again with the next update? I'm looking forward hearing from you to save all the work we had with our project. Best regards, August

Changed format of Release Notes
by Phyllis Smith 09 Dec '20

09 Dec '20

The file, releasenotes.pdf, accessible from the website under Download->Documentation will now reflect the changes that have been checked into GIT. In the past Release Notes were only updated when new builds were released at the end of the month. So if you look at the current pdf file, you will see all of the changes that Andrew has made that were tested and checked in + whatever else was.

Mixers... Mix Masters
by Rafa Mar Multimedia en Gnu\Linux 06 Dec '20

06 Dec '20

Hello friends of Cinelerra, I am going to write a tutorial on the multicamera technique, I am looking at the Cinelerra GG manual for documentation, but I cannot find information about the command "Mix masters" from the Mixers menu ... Someone would be so kind to tell me, briefly, what this option is for, or the section of the manual that talks about it. I guess it must be to indicate which track will be the master, but I don't know exactly the steps to follow to make it work correctly. Thank you very much in advance.

Not quite correct patch for toggling various windows from mainmenu->window submenu
by Andrew Randrianasulu 02 Dec '20

02 Dec '20

Well, I'm fairly sure void MWindow::hide_vwindow() kinda wrong (because copypasta!) but it seems to work for single viewer window I wanted to hide via this menu.

Is the Waveform properly calibrated ?
by Pierre autourduglobe 28 Nov '20

28 Nov '20

When I analyze a sequence of SMPT ntsc SD color bars generated by my DV camera. The Waveform correctly indicates that the black bands are at 7.5 IRE but places the white band at around 92 IRE instead of 100 IRE and the colored bands around 70 IRE instead of 75 IRE... This in a project in DV ntsc YUV 720x480 format with the preferences "YUV colors space" to BT601 and "YUV color range" to JPEG. If you choose instead the preference "YUV color range" in MPEG, the white band is correctly at 100 IRE and the colored bands are 75 IRE, but... the black bands are now wrongly at 0 IRE... So no possibility to have a good reading. This is true whether I use the X11-OpenGL video driver or just X11. I got the same results (problems) using the color bar from the Grass Valley site: http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DV25_colorbar.avi http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DV50_colorbar.avi http://www.gvgdevelopers.com/K2DevGuide/Clips2/NTSC_SD_DVCAM_colorbar.avi Is the Waveform properly calibrated ?

patch for 16:10 aspect ratio

Missing preset for SD 16:9 Anamorphic Wide DV(D)
by Terje J. Hanssen 27 Nov '20

27 Nov '20

While HDV and FHD video can rendered for Blu-ray media, the widespread DVD can only playback SD video content. HDV camcorders can during tape playback 1440x1080 anamorphic HDV content, downconvert it to Widescreen Anamorphic 16:9 video. Is it possible to get a Preset for DV(D) wide 16:9 video? References ------------------ MPEG-2 DVD-Video (Application) https://en.wikipedia.org/wiki/MPEG-2#DVD-Video 16:9 is the only widescreen aspect ratio natively supported by the DVD format. Anamorphic DVD transfers store the information as 5:4 (PAL) or 3:2 (NTSC) square pixels, which is set to expand to either 16:9 or 4:3, which the television or video player handles. For example, a PAL DVD with a full frame image may contain a video resolution of 720×576 (5:4 ratio), but a video player software will stretch this to 1024×576 square pixels with a 16:9 flag in order to recreate the correct aspect ratio. https://en.wikipedia.org/wiki/16:9 ------- DVD Video - Widescreen Anamorphic 16:9 16x9 A DVD labeled as "Widescreen Anamorphic" contains video that has the same frame size in pixels as traditional fullscreen video, but uses wider pixels. The shape of the pixels is called pixel aspect ratio and is encoded in the video stream for a DVD player to correctly identify the proportions of the video. If an anamorphic DVD video is played on standard 4:3 television without adjustment, the image will look horizontally squeezed. Although currently there is no labeling standard, DVDs with content originally produced in an aspect ratio wider than 1.33:1 are typically labeled "Anamorphic Widescreen," "Enhanced for 16:9 televisions," "Enhanced for widescreen televisions," or similar. If not so labeled, the DVD is intended for a 4:3 display ("fullscreen"), and will be letterboxed or panned and scanned. https://en.wikipedia.org/wiki/Anamorphic_widescreen#DVD_Video Terje J. H

DNxHR presets
by Andrea paz 26 Nov '20

26 Nov '20

I tried to put DNxHR presets under the .mov container. The advantages of using this mezzanine codec are great quality and efficiency (like ProRes) and being self-managed for each resolution and bit-rate (unlike DNxHD which has many fixed and unalterable formats for each resolution). The only disadvantage compared to DNxHD is that it supports only progressive and not interlaced signals. If someone wants to try them, I make them available (there are also 2 audio presets of type pcm). They seem to work apart from some settings: - Pixel_format gbrp10le of pulldown ("pixels:") does not work (it remains yuv type). - in pixel_format pulldown there is no choice for bit-depth=12; while DNxHR_HQX and DNxHR_444 profiles should be 12-bit (for resolutions higher than FullHD). Is this a limit of CinGG? - pix_fmt=rgb24 does not work. Since I can't find any official documentation, if you have any advice please say so. I based on these articles: https://dovidenko.com/2019/999/ffmpeg-dnxhd-dnxhr-mxf-proxies-and-optimized… https://macilatthefront.blogspot.com/2018/12/tutorial-using-ffmpeg-for-dnxh…
