Question / Help Capture Card smoothness

First, just wanted to say this is awesome software, thank you so much it....

Specs:
Gaming PC: 3570k@4.2, GTX 770, 8GB, SSD HDD.
Streaming PC: Phenom II X4 955 BE@ Stock, 9500GT GPU, 4GB RAM, IDE HDD, Avermedia Game Broadcaster HD.

My issue is: I just got a capture card, and I do not think my stream seems that smooth. There seems to be an odd stutterness to it. I could also be crazy. I was wondering if a hardware upgrade on the streaming machine would do anything? I don't mind throwing some $$ at this, but I also don't want to waste money if it won't do anything. During my streams my CPU monitoring software is only registering about 60-75% usage and it does not look like OBS is dropping past 60 frames or 48 frames when I watch the software.

The capture card itself seems to be getting 60fps, because the preview window video looks really smooth and my gaming PC rarely drops below 70fps in game.

obs settings: 3500 bit rate/buffer. downscale to 720p from 1080p, preset: very fast, bicubic filter. Interestingly lanzcos filter drops my obs fps to like high 40's, even @ 60 fps setting. Is there anything I can change to just make this look smoother?

Here is a sample 48fps stream using game capture from my gaming pc. I know the quality is a bit worse since I am using superfast preset, but it just seems way more smooth than the 48fps stream from the dedicated capture machine.

48 fps from game PC - game capture: http://www.twitch.tv/swk_imminent/c/2918380

Is there anything I can do to make this better?

Even with OBS downscaling? I guess I thought since the capture card was taking in 1080p@60 that obs would be able to take that and downscale to 720@60.

Thanks!

The capture card can't take in 1080p60 in the first place, so downscaling doesn't make any difference. Set your OBS base resolution and the capture card to 1280 x 720 and don't use downscaling.

Downscaling happens after the capture and compositing happens. Downscaling is one of the last things that happens on a frame before it is sent to the encoder. Think of it as a 1080p "canvas" that you put things on, and after everything is arranged and captured, then it's all shrunk down to 720p before being encoded and sent out.

Thank you for the replies. I'll probably wind up returning the card.

The part that gave me false hope was this:
The Avermedia website does say the game broadcaster HD will take an input of 1080@60fps and it will output 1080@30fps and 720@60fps. I guess I figured since I was going to re-stream at 720@60fps, that I would get 60fps.

The thing that also was confusing me was that the card is set to 1080 right now and the preview window in OBS is definitely pumping @ 60fps; the preview window also looks just as smooth as my gameplay, so I was hoping that a hardware upgrade would have possibly helped. Oh well.

I can't set the card's reso to 720p, because my PC is at 1080, and when I set the capture card's reso to 720p I get some crazy distortion.

Are there any known good capture card's that will take a 1080@60 signal and be able to re-stream 720@60fps?

Thanks again!

That card can do downscaling on the card itself. First, set your OBS base resolution to 1280x720. Then, in the properties of the capture source, manually set the custom resolution to 1280x720 and the fps to 60. That's the only way to have a 1080p60 input and display it at 720p60.

You have to downscale on the card rather than in OBS.

I tried that, but am getting distortion. I am probably missing something. PC output is 1920x1080, and I am viewing this post.

In OBS-->Settings-->Video. I Have Base reso set to 1280x720. Reso downscale of none. FPS of 60. Attached is a pic of what it looks like, and the cap card settings. When I set it back to 1920x1080, it comes back correct. :(

Thanks again for the help!

So I have updated my Capture Card to an Avermedia Live Gamer HD, and everything is running @ 60fps now. Thanks much for the help

I was able to get my hands on a hand me down GTX 260, which is sitting idle and not doing much since this machine is a dedicated streamer. Would I be able to leverage the GPU in anyway; with say using opencl=true?

The processor is only a Phenom II 955 BE, so anything I can do to give it a helping hand would be great.

-Thanks

No, and the GTX260 specifically is known to have issues with OBS as well... can cause compositing lag which can lead to delayed frames. OBS does use the graphics card (why a DX10 GPU is required) for back-end functions. I'd recommend keeping an eye on your logfiles, and considering swapping out to a more modern GPU (though top of the line isn't necessary).

Or an old Radeon 6000-series. It's doing minimal work.
As it's a standalone encoding rig in a two-system setup, I wouldn't splash out for latest-gen or even last-gen. An R7 xxx or a 7xxx would be severe overkill. A $130 low-midrange card will do fine.

Hell, even a semi-modern budget card would work well. Or just that 9500GT even, if you aren't having any problems in the logfiles. The GTX260 specifically is known to have weird speed problems with OBS, not cards of that entire generation. Just luck of the draw to get that exact card. :)

I have a GTX260 that I used in a second PC (i7 2600k OC'd to 4.3GHz) with an Avermedia Live Gamer HD, and it was bad. That video card will bottleneck you.

I keep telling myself I'm going to test this, but I don't think anyone has yet confirmed whether or not opencl=true actually does anything. I wouldn't buy a specific brand of video card just for that.

Jim has mentioned in this thread: viewtopic.php?f=5&t=5196 that stream processors (stream cores) are likely the most important aspect in a video card as far as OBS is concerned. The GTX560ti in my streaming computer works great. So find a video card with many/fast stream processors that's nice and cheap and that'll be your best bet.


Edit: This interests me, so here's more details:

Here's the GTX260 which had terrible performance (192 cores @ 576MHz, 896MB GDDR3 @ 1998MHz): http://www.newegg.com/Product/Product.a ... 6814130370
Here's the GTX560Ti which has great performance (384 cores @ 850 MHz, 1GB GDDR5 @ 4104 MHz): http://www.newegg.com/Product/Product.a ... 6814130604

I did a Newegg search for all video cards with 384 cores or more, based on Jim's previous response: http://www.newegg.com/Product/ProductLi ... 4%3A348251

I think this had the side-effect of restricting to Nvidia, but whatever.

Here's a $49 video card after rebate, GT630 (384 cores @ 1800 MHz, 2GB GDDR3 @ 1800MHz): http://www.newegg.com/Product/Product.a ... 6814121778

Compared to the 560Ti, it has the same number of cores at twice the speed, twice the memory at half the speed and 1/4th the bus size (560Ti = 256bit, 630 = 64bit). It would be a fascinating test of cores vs. memory for OBS. But I'm not going to spend $50 finding out. If you want to take the chance, please let us know!

Otherwise, I would just get this one (or widen your search to include AMD options): http://www.newegg.com/Product/Product.a ... 6814127731

Just an update. I upgraded the system to a FX-8120 processor while still using the GTX 260, and was getting 60 fps in the obs fps indicator. But the stream itself did not seem 60 fps, I attributed this to the GTX 260. So I swapped it out for a 9800GT that my friend had lying around. This morning, obs updates, and when I start obs. The fps indicator is topping out at 37fps, and my GPU renderer usage is at 75% and the clock speed is high, whereas the GTX 260's did not seemed used at all. My CPU is not being used much.

I am kind of confused as to what to do next. Does the GPU make that much of a difference or not really in a dedicated streaming system? attached are the logs for a short stream session.

It seems pretty obvious to me you need a new video card. A 9800GT is even older than a GTX260. I think I already answered this.

Yes, it does. OBS still uses it for compositing and a few other things, you just don't need as powerful of one as you would in a single-system streaming setup, where the GPU would both be playing the game AND doing all the stuff OBS uses it for as well.

So again. You don't need to buy a top-tier graphics card. But you do need a modern one, even if it's in the budget range. The GTX260 and 9500GT are not 'modern'; they are several generations old.
The card you'd linked looks like it would work fine.
