I make youtube videos and my old i5 computer wasn't cutting the mustard with 4k video (wouldn't play it at all in the editor) so I put together a new computer with a Ryzen 7 and an SSD drive that is super quick and rather impressive. However, it is still choking on 4k video. It can play 4k off of youtube just fine but the editor (Camtasia) is jerky and stuttering while playing the 4k video. It wouldn't work at all with Cakewalk by BandLab, you could press the play button and nothing would happen except the play button would turn into a pause button and that's all.

I'd really, really like to be able to edit video and record multitrack audio but this thing is just not working out as expected.

Computer specs:

• AMD Ryzen 7 3700X 8-Core Processor
• Gigabyte B450 AORUS Elite motherboard
• 16GB DDR4 RAM (Corsair DDR4 3600)
  
• NVIDIA GeForce GTX 1050 Ti
• Inland premium 512GB NAND M.2 NVMe SSD

I think there is some sort of conflict that may be stifling video performance.

I'm going to bet folks say it's your GTX1050. I have one in my 6 year old i5-4440 3.1GHz desktop machine. Graphics cards have significantly improved with their capabilities since then.

Sure, but the prices are like $600

Crud, I was hoping that wasn't the issue. I just picked this GTX1050 up hoping it would improve the situation over the GTX460 that was in it. I'd like to try something more modern but I'd like to know that's the issue before dumping a ton of loot on a video card that may not solve the issue.

Video card suggestions are appreciated. Budget is an issue here.

It really depends on how much the graphics programs you're using hand off processing to the GPU as opposed to the CPO. Given your other specs, I can't imagine you're bottlenecking outside the GPU. If the cost of a new graphics card is prohibitive, you could always look around for a lightly used last gen 1080ti with a healthy does of RAM. That card would certainly handle 4K video.

Something akin to this... https://www.ebay.com/itm/EVGA-...6:g:THoAAOSwGzpfnehb

Is it just video playback that's stuttering?

That's weird.

Even the chipset inside of a Chromecast dongle can push 4k resolution to a screen.

We're not talking rendering/capturing computations, just straight video playback?

Have you tried a different onboard player, like VLC?

If YouTube videos playback at 4k no problem, I'm going to guess it's a software problem with Camtasia. Maybe it's codec is finicky or not optimized to run with the 1050ti?

The 1050ti should have plenty of horsepower to play back a 4k video and to even to render a 4k video (if given enough time)--more power would affect rendering and videogame performance, but video playback is easy peasy.

That's what I'm thinking as well. This should run like buttah.

The strange part is that sometimes it goes semi-ok-ish and sometimes it just won't play at all. Then when Camtasia has the problem it spreads to youtube videos as well.

Do you have a program that keeps track of CPU and GPU loads and temperatures? I'm wondering if the CPU is thermal throttling.

The CPU is pretty steady at around 36°c

How many cores are being used and what frequency are the running at? From reading online, try using software acceleration in Camtasia.

Have you looked at RAM utilization?

Camtasia system general requirements page suggests 16GB or more

Camtasia 4K/60 FPS recommendations page: 16GB or more

In your shoes, I'd stuff my MB with every bit of RAM it would take. Also, I'm assuming you're flying near 4GHz: Camtasia's 4K/60FPS page recommends at least 3.5GHz.

NVIDIA GeForce GTX 1050 Ti

You might want to verify the firmware and driver for the graphics card.

A while back I ran into occasional issues with an EVGA Nvidia graphics card. It turned out Windows was upgrading the graphics card software and picking Nvidia drivers instead of EVGA drivers. In addition to that, I had to make sure the firmware and driver was both from EVGA instead of Nvidia. I also had to make sure the firmware and driver from EVGA was the correct set intended to be used together.

Almost anything can decode 4k video. My little GPU inside my iPhone can play 4K nice and smooth. The GPU bottle neck would really manifest during the encode. A GeForce 1050TI should have no problem decoding 4K video.

Are you sure you don't have a driver problem? Perhaps an older driver, or perhaps a generic software driver?

^^Looks like bryan11 beat me to it^^

Ah, I got it to rise up to 60°c running the 4k video.

I think you're on to something:


This is a camtasia issue then?

60 C isn't even breaking a sweat though. 100 C is usually around where a CPU begins to worry about its integrity. So it's likely not thermal throttling. Download Intel's "Extreme Tuning Utility" and it will tell you specifically if your CPU is throttling to maintain temperatures.

I'm still not clear on what the problem is.

Are you getting stuttering on playback of a *finished* file? That is a problem.

Are you getting stuttering on playback of an *unfinished* file? This, for a non-linear video editor (I've never used Camtasia, but I use Adobe Premiere) is normal. When you assemble video in an editor, the video isn't made until you let the software render the whole video and export it as one cohesive clip. Until then, when you hit "play" on the editing screen, your computer has to rummage around all your clips and assemble the video on the fly. Stuttering here is normal. Faster computers speeds up this "preview" playback, but nobody expects it to be smooth.

From what I see on you screen right now, I see that your CPU is pegging 100% while you have a the video preview and storyboard up. This looks like you are right in the middle of editing, and trying to watch the video as you make it. Stuttering and slow downs here are perfectly normal.

Sometimes. Sometimes it's good and sometimes it's choppy and then other times it just freezes on finished file playback.

Sometimes it plays in a choppy manner, sometimes it just hangs like above. It never plays nicely while editing.

Is the inconsistency that is really confusing.

Yeeeah. I think it's about managing expectations now.

Camtasia is an editor. It's not really meant for playback. When you open a clip in Camtasia to look at, Camtasia should be doing a bunch of things in the background with that clip to prepare it for use in a new project. This sucks up a ton of CPU power and RAM, but is rather normal.

If you are just trying to watch a video that you've made, you should be using a media player like VLC. If you are just navigating preview files in your media bin, expect lag as every time you open a file from your media bin, Camtasia is likely making a copy of it in a cache file and getting ready for the clip to be edited.

For me, on Adobe Premiere, the first time I scrub through a clip in my media browser, I don't often get smooth playback. After I've trimmed up some clips together on the timeline, the preview playback is smooth unless I've modified the clip in any way--for instance, if I applied any color effects, the computer will slow down as it gets to that part in the preview video. When it gets there, the computer pegs the CPU as it tries to colorize every individual frame for me in real time, and ends up stuttering or slowing down. In the end, after I've completely rendered the video, playback in VLC is smooth.

Oh, also, is your media being stored on the same SSD as your OS?

I saw you mention that you have a 512gb SSD in your build, but you didn't mention storage media. Just wanted to check off HDD speed of the storage media as a potential resolution.

I use the Intel Extreme Tuning Utility to see what my CPU is doing, but I was unaware it works with AMD CPUs.

mark ,
just a thought mate - have you tried kdenlive - it is open source and FREE - and runs on windows 10 and handles 4K video .
best .

Get a faster video card and then encode you video with nvenc.
