@Tomas-SVK

Hi and welcome to the forum.

I have closed your other post in the Other products section to avoid splitting of replies.

We need more information:

Computer specification - see this topic for what is required and please quote your processor and graphics card/chipset make/model in full.
What is the source of the HEVC file eg Mobile/Smart phone, GoPro camera etc?
A MediaInfo analysis of one of the HEVC files would also help, see this tutorial on how to setup and analyse a video file with MediaInfo and copy the data for posting in your reply.

Hi, tank you for the respond.

When I click on video (play button) it start to preview, but only black screen with audio. I tried proxy, still black. Works fine in Movie studio 16 Platinum.

1. Win10,64bit, latest updates, GeForce GTX 750 2GB, i5-3570K, 12GB RAM

Movie studio 18 Platinum 18.1.0.24(UDP3)

2. Gopro 9

Hi

Thanks for the quick reply.

The computer specification is the absolute minimum for running Movie Studio 18 (MMS 18) this and the Go Pro video format gives rise to two major problems:

the processors integrated graphics - HD4000, and the GTX 750 are not capable of handling HEVC video for decoding or encoding.

In the Program settings, Import/Export tab try turning off (uncheck) the 2 hardware acceleration options if they are on (checked).
If the above works, the video resolution of 2.7K with a bitrate of 100 Mbps from the GoPro, is putting a high load on the processor which means the program will be slow responding - HEVC requires a lot of processor power to decode and play.

The best solution for working with this computer specification and MMS 18 is to convert the existing video clips to MP4, h.264 encoding with 1920 x 1080 resolution using a converter such as Handbrake, and, for future video recordings, use the same encoding and resolution settings and Constant framerate in the GoPro 9 if it supports them.

Yes, it helped.

it's slow, but at least it works :)

thank you

is there any link with recommended graphics card that can support encoding HEVC?

Hi Thomas.

When John refers to your computer only just barely making the minimum requirements to run he is referring to both the Intel GPU as well as the nvidia card.

I have just exported a project to HEVC to show you how much each part of my system is being used to render the project.

You can see the workload is pretty evenly shared among the various components using both an Intel chip that has an HD 630 GPU and an nvidia 1650 Super 4GB graphics card. It was the cheapest card I could find that I felt could meet the current requirements.

You can also see the Intel GPU is working very hard.

Hi

. . . . is there any link with recommended graphics card that can support encoding HEVC? . . . .

IMHO a new computer based on an Intel processor - 6 to 8 cores is sufficient, with a UHD 630, or equivalent Iris Graphics, integrated GPU is required:

Future proofing for new capabilities that may be introduced in MMS18/Movie Edit Pro, some are already in Video Pro X 13, the addition of either:

a NVIDIA Geforce GTX 1050 or better, preferably one of the RTX series graphics card.

or
an AMD Radeon RX470 or better graphics card.

See the specification of my computer in my signature below.

@Tomas-SVK @johnebaker

Just a few more points I'd like to mention. Do look at not just specs of nvidia cards but the prices of some of them. I have found cheaper prices on some newer cards with better specs than some of the older cards. Graphics card prices at present still seem to be over priced and sometimes a ready built machine at present can be a cost saving over buying separate items. When I looked for graphics cards I could not find a new 1050 card for sale. Also going build your own would mean a new motherboard and possibly ram as well as an up-rated power supply and upgraded CPU cooler.

An nvidia card on its own at this point would not make an awful lot of difference. Better a new motherboard and CPU along the lines of Johns suggestions to start with would help much more.
