A potential HTML manual problem under NTFS/FAT filesystems
by Georgy Salnikov 31 May '24

31 May '24

I accidentally found, that in the huge list of files produced by latex2html from the CGG manual there are HTML pages, whose filenames differ from each others in the letter case only. This is no problem under Linux. But if somebody copies all the files to a Windows computer (with an NTFS-like filesystem), or to a memory stick formatted as FAT32, or to some network (Windows or Samba) disk where differences between upper/lower case in filenames are ignored by the operating system, then some HTML pages will be overwritten by others and disappear. I have found 4 such potentially conflicting pairs of page names: Compositor_Window.html - describes the whole Compositor GUI (Chapter 2) Compositor_window.html - describes the Compositor shortcuts (Chapter 15) Viewer_Window.html - describes the whole Viewer GUI (Chapter 2) Viewer_window.html - describes the Viewer shortcuts (Chapter 15) Final_note.html - about copy/paste text highlighting in Chapter 17 (How some stuff works) Final_Note.html - a link to wiki.archlinux.org on hardware video acceleration from Chapter 19 (Performance and other tips) Index.html - the Index at the very end of the manual index.html - the default start page, automatically created by latex2html as the exact copy of (hard link to) CinelerraGG_Manual.html The automatic creation of index.html can be suppressed by the latex2html option -noauto_link, and this file is not used by CGG Context Help (while Index.html is used). If renaming other sections (for example "Compositor window" to "Compositor window shortcuts" or "Final Note" to "Further topics on hardware acceleration", or something like this) is desirable, to me is open question.

OT: video about old usb 1.1 capture device
by Andrew Randrianasulu 24 May '24

24 May '24

Under old windows, too .. but as top comment says, quality is quite surprizing, considering all limitations. https://m.youtube.com/watch?v=4U32Hl4uSBs "USB video capture in 2002: Dazzle DCS 200" mpeg2 SD video (NTSC/PAL), at around 6 Mbits/s ofcourse capturing raw/lossless is superior ... if you have hd space. But I guess analog/noise filtering part in those old parts was main feature and not afterthought like on some more modern devices {echoing from comments}

Chromakey improvements checked in to GIT
by Phyllis Smith 22 May '24

22 May '24

Chromakey plugin has had its menu improved by anonymous contribution and it has been checked into GIT. (Andrea, can you test it too? and check the manual to make sure still matches and make new image?) Improvements include: - added Default button - default values for Threshold and Slope changed from 60 to 10 and from 100 to 0 as much more practical - position of Threshold and Slope switched because Threshold is more relevant (Previous 2 items were suggested by Andrea) - textbox with arrows added for much easier access to current setting - individual "reset" icons added - location of "Use color picker" put into better position - other minor stuff

Cinelerra-HV 9 is out!
by Andrew Randrianasulu 21 May '24

21 May '24

News item at linux.org.ru - because official one just few lines without any picture :) https://www.linux.org.ru/news/multimedia/17621213 Also, it was suggested that we (cinelerra-gg) can create different git branch < named, say, "testing" > for "potentially unstable" patches, like current ffmpeg 7.0 patchset and then merge back to main/stable when feature is deemed ready. So, "main" releases will be once in half year, year but they will look more like releases, with Changelog looking less like git log :)

Audio Offset Finder
by Andrea paz 20 May '24

20 May '24

A nice command-line tool that reads the offset between two audio tracks, thus allowing them to be manually synchronized. Unfortunately it is made with Python, but I was wondering if it is possible to import it into "i" shell commands, so as to provide sync information of the various assets. It has the Apache license. https://github.com/bbc/audio-offset-finder

Add to the manual
by Andrea paz 14 May '24

14 May '24

I wrote a short introduction for chapter 7 of the manual, the one with the rendering options. I am not sure it is necessary so I am attaching, in addition to the latex version, a txt version. Judge whether it should be included. In this case it should be put at the beginning, as the first paragraph.
