Manual documentation for 1 Audio Shortcut is either wrong or confusing?
by Phyllis Smith 23 Jan '24

23 Jan '24

There is a shortcut documented in the Manual, that seems to be incorrect and is certainly confusing shown last in Bold below. Audio Attach Trans. --- Open audio transition select for insert at edit boundary. Attach Effect. -- Open audio selection menu for insert at edit boundary. *Render Effect -- Open audio render select to render from select as pcm.*

Again on plugins in floating point (HDR)
by Andrea paz 22 Jan '24

22 Jan '24

I tried to make other changes to the plugins for Color Correction to be able to make it also see out-of-range (HDR) values and be able to change them. All of this involves floating point calculation. I tried changing the range of the following plugins: Alpha; Color3Way; ColorBalance; Gradient; Histogram Bezier e Overlay. If interested, I can report attempts to modify the code, but I got good results only with Color3Way. More in detail: Alpha: My modifications ruin the plugin. Probably widening the range 0 - 1.0 leads the algorithms to wrong results. However, I think the original plugin works in floating point. ColorBalance: From my tests I did not notice any difference with the unmodified plugin (I used an appimage). I am under the impression that this plugin already works in floating point and does not need modification. Gradient: Here again I find no difference with the original plugin. Again, I have the impression that the plugin already works in floating point. Overlay (shared effect): I don't notice any difference with the original plugin. Histogram Bezier: I tried extending the range similarly to Histogram (which works well in HDR, after modification). In this case I see no change. The code is much more complex and it is probably not enough to delete the CLAMP. The change I made is to the file "bistogram.C" line 361 I changed the value of 1.0 to 10.0. I also tried editing the file bistogramconfig.C line 110 e 111 I changed the value of 1.0 to 10.0. line 229 I changed the value of 1 to 10. I put these details because the plugin is very important for CC and I would love it if someone more experienced than me could make it work on out-of-range data as well. Besides, the plugin is not only a histogram but also uses the very important "Curves". For the Videoscope plugin I could not make changes because the code is too complicated for my skills; similarly to Histogram Bezier. Finally I describe Color3Way, in which the modification worked. In the original plugin the color wheels already seems to work in floating point, but not the V bar of brightness values (which are clipped). With the modification the V bar also works on out-of-range data. The modification is as follows: File "color3way.C": line 281 I changed the value of 1.0 to 100.0. line 284 I changed the value of 1.0 to 100.0 (I have also tried other values, e.g., 10.0, and the clamp always works up to those values). The floating point calculation works for both the saturation bar and the V bar. With the tests done so far, I have had no problems or errors/warnings on the terminal. I did the tests with exr images and then enabled the internal CinGG engine (but in the tests it also works with "ffmpeg first"). I set the color model to RGBA-FLOAT (inescapable: with integer 8-bit models you cannot have HDR) and the color range to 2020 NCL (but it works with all possible settings, not relevant). The graphics driver is X11 because with X11-OpenGL it does not work. Used patches: 0001-TEST-Simpler-unlimited-float-overlay.patch 0002-Allow-negative-numbers-in-overlayer.patch noclamp_in_histogram.diff Manual changes in color3way.C I am happy with the success with Color3Way (as with Histogram) because I believe it will become increasingly important to work on HDR video in the future. On the other hand, I regret not having success with Curves (Histogram Bezier) because it is an essential plugin for CC.

Donation and DaVinci Resolve EDL
by Matteo Bini 22 Jan '24

22 Jan '24

Hi Cinelerra GG users and developers, my name is Matteo Bini and I'm new to this mailing list. First of all, I would like to thank you for the amazing work you do on Cinelerra: it is a great non-linear editing software. Because of this, I would like to make a donation to support you. How can I do this? Do you accept bank transfers, credit cards... or even the horrible PayPal? My main question is about DaVinci Resolve. Is there a way to export a timeline from Blackmagic software to Cinelerra GG? I've recently finished shooting a short film, that's been edited and colour-corrected in DaVinci Resolve. I would like to edit its audio on Cinelerra GG. Do you think there's a way to move the synchronised audio clips from the two software, without having to export them by hand? Again, thank you for your incredible effort to produce Cinelerra GG and thank you for your help. -- Matteo Bini

May be you can even prepare text patch and apply it to dvd.sh ? Oh, and in case of 24-bit audio at 48 khz you definitely want to lower your video bitrate ...
