One thing to consider with these bitrates is that at such high bitrates, the major quality advantage of x264 is not nearly as impressive as it is at low bitrates. A comparison ive used: http://keyj.s2000.ws/?p=356

According to this, xvid, the second highest quality encoder takes far less cpu power while maintaining similar quality, at least at higher bitrates.

Hey guys do you all have this problem which i am currently having it with xsplit streaming on justin.tv
without xsplit I can play at 200fps on sc2
the problem is when i use xsplit... at 30fps... my sc2 fps drops to 30-60 fps and its really laggy...
it seems that xsplit's fps is sync with sc2's fps which sucks big time
I do not know why is this happening... because on my laptop.. 50fps seems smooth to me but i need 150 - 200 fps to be smooth
I tried playing on 60 fps which is pretty smooth in sc2(frames at 80-100) for me but when i use my mouse cursor to change position of the screen it starts getting jerky which really spoils the gaming experience.. any idea how I could solve this problem or should i just take this issue to the xsplit team?
Thanks...
My question is
1) how do i unsync sc2's frame n xsplits frame, because i know procaster for livestream could do such things..
2) Why do i lag when my fps is around 80FPS on my PC
but at 50FPS on my LAPTOP it is smooth.. seems weird no?
thanks guys
sorry if i have been spamming on other threads too but i really want to get this working ...

I tried to use the resolution 840X525 as suggested as my native res is 1680X1050 but when I broadcast it says that it is streaming but on my justin.tv page nothing is live, if I change the resolution to one of the default resolutions that come with xsplit then stream everything works fine, does anyone have an idea of what is happening?
|
wow now i know what i have to get an do for running smoothly a stream, thanks!!!
|
Great write up, really nice for someone like me getting into streaming with limited experience. You mention overclocking the Core i5 2500k, would it still be able to stream in okay quality even without overclocking?

sorry if it was posted but i wasn't sure if it was answered...
my upload was 3.93 Mbps. Is this good enough to stream? If so, what quality? (i think it says 1080, but im not sure if that's what it's referring to). Thanks.

ok so 720p (1280x720): 1500-3000kbps
i have 3up if i go at 2000kbps
will it be in HD ?

Ok so I have a Core2duo 2.6ghz, 3 years old graphics card, 1.5gig ddr3 ram. I have 10m/6m Down/upload. Can someone please recommend some Xsplit settings?
I tested it, and to make it not-lag I had to lower res and frames to 640x480, and 15fps. 3k Bitrate. Which looks pretty awful. Any tips?

How well do you think 4gb 1333 ram, i5 2500k, 6850 gpu could stream sc2? Download is 20mb (don't think it really matters), upload is ~4Mbps. Will this run it on ultra? High? Medium? thanks.

As far as i understood all the TL guides on streaming, that's about as good as it's going to get. You should lower your bitrate though. I don't see a reason for it to be so high while streaming at 640x480. Should be around 750kbps. Don't know if that actually has an impact on cpu performance. Maybe after that you can increase the fps to 20 which would be desirable.

How do you record 1680x1050 (or 840x525) when FMLE (VHScrCap) doesn't list that as input (output)? I've been trying everything and it both a) looks like crap and b) lags. Even when I record it to HDD and am not streaming at all. I've followed all guides listed and I just don't get what could be wrong besides the resolution thing.
I'm running an i7 2.6k with W7, 2GB Radeon 6950 and 8GB RAM so I don't think recording should be much of a problem.
Edit: deinstalled the Multicam crap and installed SCFH DSF, this is much better, but the image is quite blurry and I get artifacts when scrolling. I changed my natural resolution to 1600x900 and the SCFH to fullscreen input while setting FME output to 800x450. Result: http://www.ustream.tv/recorded/15243841 I think this could be better...
I think maybe if I could play SC2 in a window I could adjust the input resolution, but SC2 doesn't let me change my res anymore, I can only choose between fullscreen and windowed fullscreen... any ideas?
Edit2: I can get to windowed mode by manually changing it in the config file. I found out that you can change the 'confine mouse' at options - controls... the weird thing is that, apparently, SC2 doesn't want to start in windowed mode at the resolution I defined in variables.txt so I have to pull the window until it's the size I want it to be. Problem with that is that it messes up the ratio as it's so imprecise.
Final Edit: Alright, seems like justin.tv offers better quality... stream is smooth as silk and quality is neat, lowering my SC2 quality settings from extreme to 'high' helped keep me at 50-60FPS... so I'm good now. Thx for the SCFH suggestion, R1CH!

For some reason in order to get good SC2 windowed fullscreen FPS, I have to make sure aero compositing stays ON. (win7x64, windowed fullscreen 2560x1600, ati hd 5770, i7 2.9ghz)
Normally I get about 55fps in SC2 windowed fullscreen 2560x1600. If aero compositing is disabled (either by xsplit, or if I do it myself), my SC2 framerate drops to about 12 fps. No idea why this is, but if I just uncheck the box in xsplit trying to turn off aero, my fps stays high.
From casual observation, it seems like Flash Media Encoder + VH Capture caused a slightly lower hit to game performance than xsplit... but I can't say for sure. I also didn't have audio properly setup in FME, and honestly xsplit is so much easier to setup and use that I'll stick with it as long as it's close in performance.

how big is the difference between a 2500K and 2600K assuming both OC'ed to 4ghz or whatever?

I've been having an issue with dropped frames, the stream runs pretty smooth but I drop enough frames randomly that it will look jerky at times. I have an i7 and a 25up/25down connection, so my CPU and Bandwith are overkill. Here are my settings
+ Show Spoiler +<device>VHMultiCam</device> <crossbar_input>0</crossbar_input> <frame_rate>30.00</frame_rate> <size> <width>1280</width> <height>720</height> </size> </video> <audio> <device>Line 1 (Virtual Audio Cable)</device> <crossbar_input>0</crossbar_input> <sample_rate>22050</sample_rate> <channels>2</channels> <input_volume>75</input_volume> </audio> </capture> <encode> <video> <format>VP6</format> <datarate>2200</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>80</datarate>
I play the game at 1680x1050, i downscale it to 720p in VHMulticam and FME.

hyper threading. 2600k has it the 2500k does not, in games wouldn't matter for the most part, in encoding applications that can run more then 2-4 threads you'll see a difference.
http://www.tomshardware.com/reviews/sandy-bridge-core-i7-2600k-core-i5-2500k,2833-16.html
but it really depends on the software can't guarantee that would you better performance without a proper benchmark running sc2 along with various encoding software as you can see from the link above not all are created equal. The 2600k is bound to do better but by how much ionno.

is 80 dropped frames after 6 minutes normal? I have a 25up/25down connection and an i7 processor with the settings I wrote in my post above. I can't seem to find a setting to tweak to reduce the ammount of dropped frames, but I also don't know what is normal.

No it's not supposed to be this bad.
You can change the audio quality.
Tools - Settings - Channel - (Edit) your Channel
At the bottom you'll see "audio encoding".
