[CentOS] Proxy rendering of 4K
Hi everyone. I have used cinelerra for several years and love the application, so thanks to all for the hard work. I recently started to edit 4K footage from a Canon 1DX Mk 2. This is obviously very slow even with a six core processor. So I am required to use proxy files to speed things up. This worked with fedora 28. However I have changed to Centos 7.5 and now have an issue, the proxy files when dropped into the viewer are very small only taking up a small part of the window. I cannot find a way to resize these to fill the viewer window. This did not happen on fedora 28. I set the >settins >format to the resolution of the original video, then the >settings >Proxy settings to use scaler, 1/3rd size, FFMPEG Mp4 and auto proxy/scale media loads. I then import the video and drag the newly created proxy file into the viewer where it sits at a third size in the centre of the viewer window. Any suggestions welcome.

Are you performing the backup as your user during the same login session? Or is it a separate process/separate login that's doing the backup? It's possible that the I/O elevator is balancing your backup session with the I/O of the backup, making any disk activity by your login session an equal priority (i.e. competing for resources). You could always use ionice to make your backup process use idle resources. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] TLS 1.3 and openSSL 1.1.1 support
TLS 1.3 RFC has 'shipped': RFC 8446. Don't yet know all that will have to be updated to support it, but I am working on openSSL 1.1.1 beta which is available in the Fedora 29 beta. The openSSL team is looking at one more beta release (I had challenges with ED25519 certs, I will soon have an Internet Draft out on them). So general heads up. TLS 1.3 is claimed to be the cat's meow for security (I see it as a kitchen sink). There will be questions asking for when it will be available (wait until they start thinking about creating EDDSA pkis). Yet another thing for our hard working Centos team. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] grub2 - add NVME to boot from - how?
I am booting from nvme0n1p2 Disk /dev/nvme0n1: 512.1 GB, 512110190592 bytes, 1000215216 sectors This was created with a standard CentOS Linux 7.5 install with anaconda about a week ago with no issues on a Lenovo Thinkpad P50. It just worked out of the box.

I use this on several x86_64 machines without any major issues and we keep it fairly up to date based on the LTS kernel set from kernel.org. You can get it here: http://mirror.centos.org/altarch/7.5.1804/experimental/x86_64/ Here is an example repo file (look for Experimental Repository): https://wiki.centos.org/SpecialInterestGroup/AltArch/i386 (that works for both i386 and x86_64) Right now, the released kernel is 4.14.52 .. but I should be releasing 4.14.61 later today.

The latest centos-release also allows for better Atomic Host integration iwth this added for all arches: https://pagure.io/fedora-release/pull-request/102#request_diff Thanks, Johnny Hughes signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] USB disk IO
Hello - frequently I turn on my external USB 3.0 disk and back. While my machine is copying and backing up my desktop becomes very sluggish. Is there a way to change that ? I am using CentOS 7.5 x86 with a very nice processor extra cores available and plenty of memory. There is no reason the "other" cores cannot keep the desktop going.
