Rendering multi-threads
by Andrea paz 01 Jul '20

01 Jul '20

I have a CPU 8 cores / 16 threads, but the final rendering uses only one core. I tried with mp4/h264-5; webm/VP9; mkv/h264-5 e Prores. A 45 min video takes 3h 30m. I tried adding the parameters "threads=15", "wpp" which should be active by default and "frame-threads=3"; but the result is the same. On average I do 15 fps. Using h264-5 with nvenc takes 1h20m; but the CPU still uses only one core. On average I make 115 fps. Using an external engine (handbrake, which uses ffmpeg) you can use both the Cpu and the GPU; the rendering will take 10m! (but with lower quality). Since I'm compiling CinGG (note: all threads are used for compiling), maybe I need to enable some flags or something like that? Are there any customizations to do? Or should I set something in the operating system? Another question: How do you configure the render farm to use only the local CPU cores?

Hello, I wanted to ask the veteran Cinelerra users a question to see if there is any way that the subtitles can be seen in the composition viewer. [image: cinSubtitles.png] thanks.

HW in render farm
by edouard chalaron 27 Jun '20

27 Jun '20

Hi all I am using several headless machines (cin -d 1200) as a render farm. Question : If the master node is using an accelaration (HW) do the slave nodes automatically use the said acceleration ? if no but is a matter of local configuration for a slave where can I set it up ? Now, to make it more complex : if the master is running on vdpau (or CUDA) can a slave run on vaapi ? Thanks in advance Ed

Ed, we do not have a definitive answer for this and really have no easy way to test, but if we think of some way to test, will attempt it. > I am using several headless machines (cin -d 1200) as a render farm. > > My understanding is that generally headless machines would not have any graphical libraries installed or X for that matter. At any rate, the vdpau and/or vaapi software would need to be installed for usage on each client. Question : > If the master node is using an accelaration (HW) do the slave nodes > automatically use the said acceleration ? > > Without testing, we can not say for sure, but the $HOME/.bcast5/Cinelerra_rc file is used for all of the nodes, master and clients. If that file has "USE_HW_DEV vaapi" or "USE_HW_DEV vdpau", conceivably the clients would also use the designated hardware device if the graphics board can handle it. if no but is a matter of local configuration for a slave where can I > set it up ? > > I do not know if there is any way to set this up or to vary between vaapi or vdpau on different clients. The one thing you can try is to set an environment variable for specific clients like the following and hope it uses that specific Cinelerra_rc CIN_CONFIG="/pathname>/<ﬁlename_such_as_.bcast5>" {path}cin -d port# where that specific Cinelerra_rc has "USE_HW_DEV=vdpau" or "USE_HW_DEV=vaapi" appropriately. Alternatively, an environment variable can be set and tried. For example: export CIN_CONFIG=/tmp/.bcast5 or even export IN_HW_DEV=vdpau or export CIN_HW_DEV=vaapi It looks like this will take some effort to figure out and if you do find something, please let us know.

BIG mod checked into GIT concerning Audio - need testers
by Phyllis Smith 25 Jun '20

25 Jun '20

Concerning BT #433 - Audio tracks improvement request from Glen. A demo is at: https://streamable.com/2ia9sz There are static tars for testing at: https://cinelerra-gg.org/download/testing/cinelerra-5.1-debian10-x86_64-sta… https://cinelerra-gg.org/download/testing/cinelerra-5.1-mint18-x86_64-stati… https://cinelerra-gg.org/download/testing/cinelerra-5.1-mint19-x86_64-stati… There is an additional toggle button at the end on the main timeline controls (where the transport icons, generate keyframes, ... are) with the default mode being the normal way Cinelerra has been working. If you never use this button, everything "should" work exactly as it does now. The mode is saved across sessions and is in your saved configuration. There is also the "Master Track" button on the right hand side of the patchbay that should be of no initial concern. GANG_NONE -- the button icon looks like 3 tracks with ... on the end. This is the "gang_NONE" mode. GANG_CHANNELS -- the button icons looks like 2 tracks. This is the BT 433 mode where *stereo tracks are treated as 1 audio track for the purpose of making changes on that single track which are propagated to all of its other channel tracks automatically*. This is the requested DAW-like mode. If you have 6 audio channels and are in this mode, they will be subject to the same edits. GANG_MEDIA - this mode only shows the first track of the media but the changes are propagated to the appropriate other related tracks. Although this sounds a little difficult, it is expected that everyone will likely work in the default GANG_NONE mode except for the DAW users who want stereo tracks to be treated the same in the GANG_CHANNELS mode. Lots of testing is needed to include just using Cinelerra in the normal mode to ensure that there is no unintended changes in the default case. A couple of problems that we just found and have not been fixed yet are: the automatic "shared track" attachment of a plugin might show up in the wrong edit. PLEASE provide any feedback as soon as you find anything. GG/Phyllis

Video for Youtube channel
by Andrea paz 24 Jun '20

24 Jun '20

I wanted to propose the raw version of an informational video for the Youtube channel. I would like to receive criticism and suggestions. E.g. is it better to have one long video or to divide it into several parts? The intermediate parts where slow configurations or slow passages are shown, is it better to cut or accelerate them? Other ideas? NOTE: if you want the project files, I can upload them to Google Drive. NOTE 2: Do you like my pretty voice? I'm kidding: it is the Phyllis' voice!!! https://drive.google.com/file/d/1OkHIm2gxnZuUSue3BJsHz0lFtw35y8dy/view?usp=…

Reverse playback hack
by Andrew Randrianasulu 21 Jun '20

21 Jun '20

Hi all! While testing .prores files I noticed I missed this codec in my hack for faster reverse playback of I-only video tracks ... Now I added it there, and on my 4 core AMD reverse playback (2x, 1x) indeed faster now. I wonder how much I break shuttle controller higher speeds or complex plugin chains?

Source=ProRes; render=low quality
by Andrea paz 18 Jun '20

18 Jun '20

Hi, To make a video, I recorded the screen as mkv/h264; then I encoded it as prores as intermediate and finally I rendered the project as mp4/x265. The parts of the project that are not derived from Prores look good; those that concern Prores are darker and above all of poor quality and illegible writing. Can you tell me why? https://streamable.com/x3ay1r
