Blue Banana
by Andrea paz 28 Oct '23

28 Oct '23

I own a book on Color Correction that is outstanding in the quality and clarity of its explanations. The book is "Color Correction Handbook" by Alexis Van Hurkman, which I recommend to those interested in grading. There is a whole sample chapter on the publisher's website about HSL Qualifiers (our Blue Banana); try to read it because it is really extensive and useful to us CinGG users as well: https://www.peachpit.com/articles/article.aspx?p=1681373

Histogram plugin
by Andrea paz 22 Oct '23

22 Oct '23

I was rereading the manual about the Histogram plugin and there are things that I don't understand: 1- Is there no longer a frame interval averaging function (Frames button)? When was it taken out? Perhaps on this occasion? https://www.mail-archive.com/[email protected]/msg02691.html (moreover, the images are to be replaced) 2-I don't quite understand the concept of "Sum" instead of "max." The explanations are not clear to me. Can anyone clarify to me the behavior of the plugin with respect to Histogram Bezier, scopes and various color models? The explanation in the manual (section: Theory) is taken from here: https://www.mail-archive.com/[email protected]/msg01834.html

Varied Standard Shortcuts AppImage version for testing
by Phyllis Smith 13 Oct '23

13 Oct '23

There is a modified Shortcuts AppImage version for testing on 64-bit O/S which is set up to be more in sync with what is considered to be "Standard" shortcuts for NLEs.. IgorB uses these and prepared a listing of the alternatives as shown below. If there are users who test these and prefer the more Standard ones, I can create an AppImage at the same time as what is released. It is currently at: https://cinelerra-gg.org/download/testing/modified_shortcuts.AppImage --------------------- Changed shortcuts to Standard Shortcuts - only English version for the caption/hints. The texts in the menu and the captions of the icons, written with the '-' character between the Special key and the key, for example "Shift-s", have been replaced by the '+' character. And the letters are always in capital letters although Shift is not pressed. Many, if not all the other NLE programs use this notation. Some shortcuts like "BD Render... (Ctrl+Shift+d)" and "DVD Render... (Alt+d) have been deleted because they are not used frequently. These shortcuts are very useful because the keys more frequently used have priority in editing: one hand (left) on the keyboard and the other hand (right) on the mouse. /* ********************************************************************** */ Goal: Changing some shortcuts to a NLE's standard shortcuts. For example: J - K - L (Play Normal reverse - Stop- Play Normal forward) if pressed twice J (or L), its Play Fast or Normal. I - O (InPoint - OutPoint) A - S (Jump backwards next cut - Jump forwards next cut) If an shortcut on After column has a '+' symbol (for example: + 'I'), it means that it is added to the old shortcut/s on Before column and also that that shortcut has been take from an old shortcut (of course), which it has another key. ----------------------------------+-------------------+-------------------+ Description | Shortcut | Before | After ----------------------------------+-------------------+-------------------+ -To clip | 'i' | Ctrl+I -Scroll window timeline... left | LeftArrow, ',' | LeftArrow -Scroll window timeline... right | RightArrow, '. | RightArrow -Label | 'l' | ''' (single quote) -Go to | 'g' | Ctrl+G -Generate keyframes... tweeking | 'j' | 'G' -Jump forward... next Keyframes | 'k' | Shift+Right Arrow -Jump backwards... next Keyframes | Shift+K | Shift+Left Arrow -New Project... | 'n' | Ctrl+N -Load files... | 'o' | Ctrl+O -Save | 's' | Ctrl+S -Save as... | Shift+S | Ctrl+Shift+S -Save Session | Ctrl+S | (null) -Select-> All | 'a' | Ctrl+A -Deselect All | 'a' or null | Ctrl+Shift+A -Select Edits | Ctrl+Alt+' | Ctrl+Alt+A -Undo | 'z', Ctrl+Z | Ctrl+Z -Redo | Shift+Z | Shift+Z -InPoint | '[', '<' | + 'I' -OutPoint | ']', '>' | + 'O' -Play Normal reverse | NumKP 6, Alt+O | + 'J' Normal&Fast -Play Stop | NumKP 0, Alt+M | + 'K' -Play Normal forward | NumKP 3, Alt+L | + 'L' Normal&Fast -Jump backwards to the next cut | Alt+LeftArrow | + 'A' -Jump forwards to the next cut | Alt+RightArrow | + 'S' -One Frame back | NumKP 4, Alt+U | + ',' (comma) -One Frame forward | NumKP 1, Alt+J | + '.'

Lossless encoding
by Guillermo Martínez Jiménez 10 Oct '23

10 Oct '23

I've been searching but I didn't find it. What's the best lossless video encoding, recommended for temporary clips? For example, as output after sound sync, color fixing, VFX (chroma key, deformations...) etc. and use them to continue editing. Thanks, Guillermo

Sound synchronization
by Guillermo Martínez Jiménez 10 Oct '23

10 Oct '23

Hi, I'm not completely new to Cinelerra but I don't use it very often. Recently I installed version 8 and I'm having issues with sound synchronization. If I reproduce the clip video on VLC, the sound is in sync but Cinelerra isn't able to sync it. I tried changing the audio offset in Preferences but it doesn't work. I've found that the first second or so the video is accelerated, it doesn't matter where I start the reproduction. I'm using a clapperboard so I know when the sound should be in sync. The video file information is: File format: Quicktime for Linux Bytes: 20,060,842 Bitrate (bits/sec): 2,711,599 Audio Compression: MPEG4 Cannels 1 Speed: 48000 Bits: 16 Bit Linear Video Compression: H.264 Frames/sec: 29.64 My computer is a bit old: Cores: 2 (4 logic ones) RAM 8GiB OS: Debian 12 No SSD, but it is new (1TiB). Cinelerra version: 8 (Installed few hours ago). Thanks for your time, Guillermo Martínez J.

Lock an asset within the EDL
by Stefan de Konink 09 Oct '23

09 Oct '23

My enormous "what I would love to have as UX' is something that is still on my todo list, but I am currently editing (again) a massive project. Now using the method of dailies, which effectively means placing all assets on the same timeline, and cut out the best takes. Since my biggest nemesis still is to sync audio against my videos I wonder if anyone knows if we allow to lock a specific asset (not track) on a fixed position on the timeline. Hence it should never move or be split. -- Stefan

SVG plugin vs Filter in file selection
by Stefan de Konink 08 Oct '23

08 Oct '23

Hi, In virtually any project I am using the SVG plugin in order to make some titles. One of the effects is that every time after I have used this plugin, any file selection in the future (even in a new project) initially sticks at the last set *.svg, which should then be manually changed in the desired selection. Is this something that the plugin itself should unset? -- Stefan
