Yes. Also, ran a test WHILE streaming yesterday and it still said about 4+ mbit/s. My stream was set to about 1000 kbit/s so it made sense.

I do not believe my connection is the problem.

The only time the problem seemed to decrease is when i selected a smaller region on my screen. However this is not a solution since my goal is to stream in HD (at least 1280*720).

EDIT: FYI, I got Xsplit working (finally) but regardless of my settings, I still have the same problem with the image pixelation during motion.

If you don't think your connection is the problem, then it could be your computer. If the issue goes away when you lower your resolution, it could point to that conclusion. Have you tried lowering your data rate?

I've tried different data rates, different resolutions, different formats, different software...

Then again, I also notice it in many other streams as well ("HD" streams). It's just not as noticeable on theirs.

I'm not sure if you posted this, but where are you located? US? UK?

I'm in the US, in southern california. When I go to speedtest.net, my default test server is in LA.

Hello, I just registered to tell you guys my problem I have.

My main problem are the frame drops I'm getting.

Here's some relevant settings from my xml file.

    <capture>
        <video>
        <device>Dxtory Video 1</device>
        <crossbar_input>0</crossbar_input>
        <frame_rate>25</frame_rate>
        <size>
            <width>1280</width>
            <height>720</height>
        </size>
        </video>
        <audio>
        <device>Line 2 (Virtual Audio Cable)</device>
        <crossbar_input>0</crossbar_input>
        <sample_rate>44100</sample_rate>
        <channels>2</channels>
        <input_volume>75</input_volume>
        </audio>
    </capture>
    <encode>
        <video>
        <format>VP6</format>
        <datarate>2000</datarate>
        <advanced>
            <keyframe_frequency>10 seconds</keyframe_frequency>
            <quality>Good Quality - Good Framerate</quality>
            <noise_reduction>None</noise_reduction>
            <datarate_window>Medium</datarate_window>
            <cpu_usage>Dedicated</cpu_usage>
        </advanced>
        </video>
        <audio>
        <format>Mp3</format>
        <datarate>96</datarate>
        </audio>
    </encode>

And here's my Speedtest results:


And finally some relevant PC Specs and what programs I'm using:
i7 920 @ 3.8 GHz
Patriot 6 GB RAM
ATI 5850
Corsair 120 GB Force SSD (if it matters :P)

For screen capturing I dropped VH Capture for SCFH DSF and then DXTory.
Input is set to 1680x1050. SCFH DSF and DXTory resizes it just fine while VH Capture requires more fine tuning.

And for audio I use VAC (Virtual Audio Cable)

From my own experience I can tell that

            <quality>Good Quality - Good Framerate</quality>

is the one causing lots of frame drops depending on which setting it is on. Best Quality causes a lot of frame drops while Good Quality is still acceptable.

I can't see why my computer is causing the frame drops. And my bitrate is set pretty high. I usually stream with 1500, but now I'm experimenting with 2000.

Can anyone help me?

I'm no pro, but I would imagine you should probably lower your keyframe frequency. Why do you have it so high in the first place?

Well, technically I mean to increase your keyframe frequency. A lower number is an increased rate. I think 10 is not frequent enough. Try 1 and see if that helps.

[Steverman]

I've used a high keyframe frequency in the past and it usually caused more frame drops. I'll do a retest.

EDIT:

Results: 217 vs 212 frames dropped within 40-50 secs. Not much of a difference but I guess I can lower it then . Keep in mind that this is with my current setting, not with best or great quality.

I apologize if I'm wrong.

I found this in a forum:
"You see that option for keyframe frequency in fme? If its on 1 second, that means that every second it uses badwidth to send All the pixels of a single frame. Every frame after that is just the information about the pixels that changed until the next key frame. The more of those frames you have the higher the quality but the higher the bandwidth."

On a side note, that same thread covers the problem that I am having. How convenient.

[Steverman]

Alright, tried Best Quality, Lower Framrate with 1 keyframe frequency. It's too laggy when I rewatch my achieved stream. Total frame dropped was 738 in 44 secs. It's pretty odd because my ingame FPS is between 50-75.

My advice: Use Good Quality, Good Framerate or lower to avoid frame drops.
