I had two surprises. First, for a 4-minute, 20-second project, rendering time went from 50 minutes with h265 (Ryzen 7 + 32MB of RAM) to 30 minutes with h265-nvenc and an Nvidia GTX 1050 Ti (VDPAU setting in preferences).

But when I did the exact same render with h265-nvenc and an Nvidia GTX 1080 Ti, which is at least 200% more powerful, the rendering time remained exactly the same at 30 minutes!

Is this normal?

Recently my Nvidia graphics card (GTX 1050 Ti) failed, and I found an AMD Radeon card (RX 590) in my spare parts, which worked for me and even seems to be working well. So I'm wondering which is better for use with CIN? AMD or Nvidia? (I read that for certain uses, CUDA with Nvidia is very efficient).

Thanks in advance for your help.

I have a firewire card installed; ieee1394

I have a sony miniDV camera connected.

When I click File>Record then I see a two screens; Recording and Video In

The Record window immediately starts the Position timer clock; starts counting and I can not stop it; I end up having to reboot or Killing the process. When I click "Close" stop without pasting into project nothing happens. 

The Video In screen does allow me to control the sony camera; play, stop, rewind ect; however, the Video In screen is black; no image appears.

How do I fix both problems?

I sold all my drones stuff to have some money to be able to invest in other filming stuff. I'm going to do filming with my Crane M2-S gimbal for the near future only.

My RX100VA is a good allrounder but has lots of disadvantages. I still have it because of the modern movie AF and the super Slomo abilities. The lens is not interchangable. I don't see enough at the screen and so on. I'm not in love with it. And I really hate the small buttons.

I still have an old Nikon D3300 which is absolutely outdated, which lacks any good AF capability, which lacks 4K video at all but which makes just a good image with both kit lens, which has a great handling and which has a absolut reliable storage file system.

If I hadn't anything I'd go with Fujifilm X-H2s or the X-E2 because I do not love Sony or Canon. I have this Nikon which I'm a bit in love with and I would prefer Nikos APS-C as system for lenses over Sony or Canon.

What do you use?

Though some will try the upgrade - many won't. Especially companies are renewing their systems.

If you use linux only you won't care at all.

I bought a cheap Dell workstation T5810 two years ago and they are becoming even cheaper - real bargains now.

Ridiculous cheap ECC memory, up to 22 cores with 44 threads they are good rendering machines for cin - and super cheap.

With 140W TDP (22 cores) they are similar at wattage to the most modern 12 Core CPU Ryzen 7900X (170W TDP) but of course not that powerful.

But for this money a real bargain if you ask me. Only the CPUs costed 2700$ (e5-2697v3) or 4100$ (e5-2699v4) in 2014.

Ten years old - yeah I know that's not interesting for everybody and not best for gaming. But cin is so super efficient with rendering with ffmpeg that these old flagships are still superior. Nothing I'd buy if I had a modern CPU like a 5600x or better. But if you're looking for a super cheap rendering machine this could be interesting. For me it is.

I bought an upgrade CPU (e5-2697v3) with 14 Cores, 28 Threads, Turbo Freq @3.6GHz and a huge 45 MB 2nd Level Cache for 20$ yesterday (inclusive shipping, invoice and warranty).

I created a 1000 fps Slomo and this pulsation is a problem.

And i can't get Nvidia GPU utilization.
The render runs via CPU.

Here is the information that proves I can run applications through the Nvidia GPU:

 I can successfully run apps with Nvidia GPU utilization, e.g. games on Wine.
But CinGG doesn't utilize the Nvidia GPU in Nvidia Prime mode via GPU offload if i run the render via h264_nvenc.mp4 profile
