Intro
Dear readers,

Currently I am trying to get the best settings to record 1080p in 60FPS for Youtube. Also the corresponding render settings for Sony Vegas Pro (12) would be a great plus!

What I'd like to achieve is the best option to use to get the best quality my PC could possibly bring.
I will also provide x4 youtube videos examples and describe what I did with it.


My PC Specs:
Processor: i5 2500K @4.7Ghz
Videocard: 7950 with 3gb @1100Gpu
Ram: 8GB @1600Mhz
OS: Win7 64bit
Hard drives: 1x SSD samsung 840 250GB for games
1x slow 1TB disk for downloads
1x dedicated 3TB HDD for recording (Seagate Barracude 170mb write speed)


OBS Stuff I've tried:

x264
-Tried to record 1080p 60FPS with x264 but that didn't really work because CPU load gets to high, tried this with CBR enable/disabled, CFR enable/disabled, and Bitrate from 7000 up to 18000 all bring to much load to my CPU so getting decent quality isn't an option.

Quicksync:
Enabled Quicksync and I almost completely removed the CPU stress! Good news..!
I was able to record somewhat fine, but there was not that much info I was able to find on Google or these forums regarding the best Quicksync settings for local recording in 1080p 60fps.



''Youtube Quality ''benchmarks Please watch FULLSCREEN in Chrome''
Sofar this was the best I could come up with using Quicksync to record Crysis 3 and Battlefield 4:


Crysis 3: Mostly medium settings (custom) 1080p 60FPS:

Raw recording with OBS+Qsync:
Original 40Mbit Qsync recording uploaded straight to Youtube, without rendering/editing so only downscaled from YT:

Rendered:
Crysis 3 in 1080p 60fps Rendered footage with Sony Vegas to 10.000Kbps as AVC/MP4, afterwards YT downscaled:
http://youtu.be/3_rtDsA_3AM (Can't Post more then 1 media video in this (Mod?? please?)


Battlefield 4: High preset, directX (mantle bugged recording ''game-capture'' mode)

Original recording with Qsync, no rendering:
Battlefield 4 in 1080p 60fps Recorded raw footage with CBR on, Bitrate 20.000:

Rendered video:

Battlefield 4 in 1080p 60fps Rendered footage with Sony Vegas to 10.000Kbps as AVC/MP4:

Is this reasonable quality?? Or does it simply suck?
What can I do to improve with settings? Or do I need new gear if I wanted to.



With Kind regards,

Mr.Google

My understanding is that QuickSync/NVENC just can't compete with a proper x264 setup quality wise. Don't take my word for it that this is an absolute, but that's my experience as well. There may be considerations I don't know about, but you might want to take a look at this page and learn a bit more about custom x264 settings. There could be ways to enhance the x264 quality without using too much CPU by using proper settings. Getting it just right is a form of art.

i5 2500k can barely stream 1080p30 on veryfast preset in this case streaming/recording has the same encoding effect on the cpu

so your cpu simply cant keep up especially with those kind of games

if theres no way around ultrafast is the preset to go... and then play around with the bitrates or even let the encoder decide how much bitrate is needed (huge ass files)

since you are on an amd cpu theres no shadowplay, yes amd has its own software but i've never used it.



so far so good your only real option is sticking with qsv and tbh at least the crysis 1080p60 vid looks amazing


can you improve quality? maybe depending on your set bitrate im not sure how qsv works when you put the buffer on 0 but i think its not the same as x264 so probably starting at around 25000 bitrate/buffer and

obviously cfr checked but cbr doesnt really have to be checked when it comes to local recording

Thank you very much for the time you took to write me a reply =)
The crysis 1080p60fps was also recorded with q-sync@40.000 max bitrate+CBR and OBS on my second monitor is not displaying the red warning message in red, which it does with x264 unfortunately.
I do not know if actually gets proper 40000bitrate quality tho with my CPU.

I did also try to record with AMD software but that can't compete with shadowplay, shadowplay is just awesome and AMD is still in Beta and not advanced enough.

For local recording I am trying right now it seems that quick-sync without CBR and 15.000kb/s bitrate seem pretty good. Any chance you have an idea of what the i5 2500k limit it??

My second option right now is to use DXtory and record lossless on a dedicated HDD, that seems to work but you can not edit scenes and stuff like with OBS what I normally use.

Thank you sofar everyone, I will try messing around with x264 aswell

theres no real limit just an diminishing return somewhere

you can feed the encoder pretty much every bitrate you want

probably around ~20k the quality is at a point where its hard to tell the difference between 25000 and 20000 already


the actual problem is rather the hdd which is limited to a certain read/write except for ssd's pretty much ... since they are so insanely fast that the required bitrate to max it out is so high its not even a point to think about
