Question / Help Bitrate and FPS

[MTSimpson82]

I am going to start streaming and i have a i5-3330 3.0GHz processor & useing and ElgatoHD60 to record game play & I have a 5.5 mbps upload the graphics card I have is GeForce GT 640... I am using downscale from 1080p to 720p... What should be my bitrate & FPS and my x264 CPU preset

Start around 2500kbit and 30 fps for 720p and see how that works. The log file was unfortunately incomplete (just the gamecapture log) so you might wanna do a bit of testing and then show us a new log too. But these values should be a good start.

 

[MTSimpson82]

ok how long should I stream for it to record a log?

 

[Jack0r]

It will write the log right away, but if you have 5 minutes, thats a good time for a test. Maybe run a game / video / whatever you are going to stream, to stress the system a bit while doing it :)

 

[MTSimpson82]

ok does it have to be streaming or can i just record?

Looks pretty fine. A few duplicated frames, but if the stream was fine I wouldnt worry too much about that.
I noticed your elgato input is already set to 1280x720. Now OBS base resolution is 1920x1080, so it has to upscale the image from the elgato, before it will downscale the final output.
I think you mentioned streaming games as well, so you could do the following:
You could use two profiles, the one for your games on the PC you keep as it is currently, base resolution 1920x1080 and downscale that to 720. But for the elgato you create a new profile (and maybe also a new scene collection if you want) and in this case set the base resolution in OBS to 1280x720 and no downscale. So it fits to the input of the elgato.
You can of course just keep doing it like you do now, but the quality may slightly improve by using two profiles :)

Oh, one last thing, on the elgato, activate "Use Buffering" and leave the buffer on 0. (That is recommended for this device)

My elgato is set to 1080p 60FPS, I have the elgato HD60

Oh oki, in the log it said:
chosen type: UYVY, usingFourCC: false, res: 1280x720 - 1280x720, frameIntervals: 166833-166833
But then nevermind :)

Did you have any problems?

 

[MTSimpson82]

no is there anyway I can up the quality?

We can see your deleted post. Don't bump your post like that please. Sometimes we don't always have all the answers to provide.

 

[Jack0r]

To increase the quality you can:
- increase the bitrate
- Selecting a different x264 preset
- lower the resolution (use the downscaling)

(Jim edit: Clarification on the lower resolution equaling higher quality, it's not so much an increase of quality more than trade-off of quality. Less resolution = less costly in terms of bitrate)
