Capturing DV/HDV via Firewire
by Terje J. Hanssen 28 Feb '23

28 Feb '23

IEE 1394 / FireWire (Apple) / i.LINK (Sony) has been a standard connection to transfer native DV and HDV video files to Lin/Win/Apple computers. * FireWire DV/HDV recording should still work via dvgrab, vlc, guvcview, OBS and ffmpeg etc., or directly via some NLE systems. * The basic dvgrab tool is still valid on Linux and was mentioned in the Cin-CV wiki sect. 19.2 * http://cinelerra-cv.wikidot.com/cincv-manual-en:capturing-media#5 * ffmpeg enabled FireWire DV/HDV input device using libiec61883 (Streamcopy) seems also interesting. On my Leap 15.4 or Tumbleweed, ffmpeg-5 is seemingly not compiled with --enable-libiec61883. Is possibly ffmpeg available with enabled libiec61883 via Cin-GG? http://www.ffmpeg.org/ffmpeg-devices.html#iec61883 http://underpop.online.fr/f/ffmpeg/help/iec61883.htm.gz I had a look into the Cin-GG manual chpt 13 "Capturing and Recording Media", but could not see Firewire media transfer was mentioned. However, in the Appendice section B.2 Configuration Features, Optional Packages is found: --with-firewire use firewire (auto) --with-dv use dv (auto) Does this mean that Firewire/dv capture already is supported or optional can be configured?

Virtualized Fedora armhf
by Andrew Randrianasulu 27 Feb '23

27 Feb '23

So I was looking at easy way to get fedora-arm/aarch64 (because install is so slow ....) May be this guide can help (assumes Fedora as base os): https://michel-slm.name/posts/2020-08-20-fedora-armhfp-vm/ while I looked at slightly different image location, for newer os image (2.8 gb for xfce4 image!) https://dl.fedoraproject.org/pub/fedora/linux/releases/36/Spins/armhfp/imag… namely https://dl.fedoraproject.org/pub/fedora/linux/releases/36/Spins/armhfp/imag… for Fedora 37 I only found aarch64 image (small one, so you need to install a lot!).. https://dl.fedoraproject.org/pub/fedora/linux/releases/37/Cloud/aarch64/ima…

OpenCL again
by Andrew Randrianasulu 27 Feb '23

27 Feb '23

So, I run veeery experimental clvk (OpenCL via Vulkan) on my termux, ffmpeg tried to init filter but died. I guess my day is not today ... Anyway, my test line was: ffmpeg -init_hw_device opencl=gpu -filter_hw_device gpu -i ~/20210419_055507A.mp4 -vf "hwupload, boxblur_opencl, hwdownload,format=yuv420p" -f null /dev/null for different filters format might be yuv420p or nv12 ... I wonder if anyone here have working OpenCL ffmpeg setup ? I'll try with llvmpipe/rusticl on desktop .... but it guaranteed to be slow.

Natron, background render and MantisBT #635
by Andrea paz 17 Feb '23

17 Feb '23

I am writing in the mailing list because today I cannot post on MantisBT. However, we had gone OT from the original request. @Andrew-R Your idea of how to do the Natron/CinGG interaction is also mine, otherwise you fall back to rendering to go to another program and then again rendering to go back to CinGG. There is imagelist.sh (https://cinelerra-gg.org/download/CinelerraGG_Manual/Image_Sequence_Creatio…) but I could not get it to work. Other solutions found on the net also do not work for me. Sorry, my inability... Natron (Write node) overwrites the imported images, keeping their exact name (which is the frame number) and path. These are read by CinGG: until a new background render starts, on the Compositor window we see the frames altered in Natron. However, this sequence of images applies only to the timeline view: if we add filters or do a final render of the project, the original source is used and not the frames altered in Natron.

A resource for Audio-Visual Preservation using FFmpeg
by Terje J. Hanssen 17 Feb '23

17 Feb '23

I came across what seems to be a great web resource for Audio-Visual Preservation using FFmpeg cross platform. This resource is released under a CC BY 4.0 (Creative Commons) License and provided “as is” without warranty or support of any kind. Most of the content is in English, a smaller part in German only https://avpres.net/ Tutorials (under work) * Bash Cookbook for Archivists * FFmpeg Cookbook for Archivists Especially the latter "FFmpeg Cookbook" seems for me to be a great tutorial and reference using FFmpeg code syntax. An example: Filter image - Pad 4:3 into 16:9 https://avpres.net/FFmpeg/4-3_16-9

Workflow issues for multitrack editing
by Stefan de Konink 17 Feb '23

17 Feb '23

When I am creating content I am typically using 2 or more camera's, each with indepedent recordings. Much of my time goes into the alignment of such recordings. Within Cinelerra single files have some scratch area using the viewer to set in and out points. Still the viewer does not show an audio waveform while editing. And certainly does not allows the alignment of two or multiple tracks. When I am editing I would love to have something like a *multitrack* scratch space. The only way I am aware of that can achieve this is creating a second Cinerella instance working on its own EDL. This would allow me to edit some 'sub project' that can later be imported again. When *reviewing* content, it is not obvious at all which files should be part of these subprojects in the first place. Sure there might be a specific section (or take) that would be on camera A and B, but camera C might have a continuous recording not falling in the category of take. I wonder how people approach these subprojects with respect to workflow and quality. Once you have set up a take, would you bring that take to the main project? Would you first render it? What are best practises for this? -- Stefan

Working on adding GPL license attribution for all program files
by Phyllis Smith 15 Feb '23

15 Feb '23

As Andrew pointed out: "GPL license states each file should have attribution ...." so I checked into GIT the addition of missing GPL information for the *guicast subdirectory *and am working on the cinelerra subdirectory and eventually plugins subdirectory. Some notes: 1) When header missing, first checked to see if file exists in Cinelerra HV-8 or CV. If files existed there but no header, used header in like files. For example, bccmodels.inc in HV-8 had no header but bccmodels.C did, so used the same one. 2) Files, like bootstrap.c, that exist in HV and have no header, I left unchanged because I have no idea where this file came from and it has an extension of lower case "c" instead of upper case "C". 3) Any file in Cinelerra-HV that did not have the Copyright/Name/Year, I did not change in CinGG, so that it would match. If Andrew has time to verify and thinks something should have been done differently, please let me know.

ms2130 hdmi-usb dongles
by Andrew Randrianasulu 13 Feb '23

13 Feb '23

https://www.cnx-software.com/2022/11/07/ms2130-based-4k-hdmi-to-usb-3-0-vid… "I learned about the video capture dongle via Mateusz Starzak <https://twitter.com/MateuszStarzak/status/1589595781971181568> who purchased a sample on Aliexpress <https://s.click.aliexpress.com/e/_Dd6uEUB> and confirmed support for uncompressed YUV @ 1080p60. He also mentioned the latency to be around 6 to 11 frames depending on the resolution with 720p input to 720p output only looking slightly faster than 1080p input to 1080p output." well, I hope Terje's camera can be switched into hdmi progressive output mode ..... contain few links. Of course main problem is verification ..... if they just paint them (usb connectors) blue for no reason ...:/
