Uhhh... if your CPU is hitting that temp at full load, then maybe you should tweak your fan curve a bit...

Well, I imagine that there's a reason the SVP wiki page for configuring MPC-HC does not mention CUVID at all.

Nevertheless, if you're that concerned about it, you can always try 48hz instead.

Alternatively, you could even *gasp* lower your screen resolution to something that you know supports 75hz and then make a custom resolution at that same resolution but with a refresh rate of 72hz.

Anyway, regarding the actual encoding, everything seems fine with the 18-second test clip I tried.  However, I couldn't help but notice that the bitrate even at the higher encoding setting is a bit low... the source was 3.5Mbps @ 720p25 while the final encoding was 5Mbps @ 720p60 - unless the program calculates the increase in bitrate based on what the source bitrate is combined with the resulting resolution and framerate?  Then in that case it'd likely be fine since my main worry was for things of a higher bitrate.

Secondly, I also noticed that the resulting video is 59.97fps rather than a flat 60fps.  Considering that I'm encoding from a flat 25fps and SVP has the 2.4x option for 25--to->60 which would also result in a flat 60, I'm wondering if the final encoding will actually have the video be a teeny bit slower than it should be...

Thirdly, with a long video (read: 1+ hour), you need quite a lot of disk space... I did not realize this as I was using an 8GB ramdisk for the program's temp folder.

Lastly, the interpolated framerate choices are quite limited - there's minimal choices for 24fps and especially 25fps content if you want to do an exact multiple of the source framerate that is greater than 2x.  Yes you could use 120fps for 24fps, but there really should be some thing(s) in the middle like 72fps and 96fps, not to mention 75fps and 100fps for 25fps content.

EDIT:, and the big one - the encoder can't browse your hard drive for videos!  It insists on only looking in the specified NGP folder, so I'm cheating by using symbolic links.

EDIT 2: Oh. my. bloody. nora.  8GB of TEMP data only encoded a whopping 1 and a half minutes?  The whole video is over an hour!  I don't even have a single hard drive that's 500GB except for a single USB 2.0 external drive, but that would take forever!

EDIT 3: I just realized that the preview.avi isn't even interpolated...so why does NGP even need decode the source video into a lossless format then?  Can't it just decode directly from the source video file?

EDIT 4: Whelp, I know why I can't decode directly from the source file now.  Simply put, it doesn't work - it just gives me a video with a black screen.  What I tried to do was select my video, then delete the preview.avi file (which normally it doesn't let me do, but for some reason it let me do it one time), and then copy my own AVI file and rename it preview.avi and put in into the according Temp folder.

So just to clarify, is it safe to assume you're using an AMD CPU with an AMD GPU?

Then get an 8-core i7.

Or wait a year for Zen.

Apologies for the double-post, but I just realized - you're testing in Windows Media Player?  WMP doesn't support replaygain, so how were you handling the volume difference for ABX-ing between AAC and Opus?  I mean, it's known that the human ear will treat sounds that are even the slightest bit louder as sounding better...

UPDATE: For example, your "Michel Teló" example has the AAC version being 0.03dB louder.

...or maybe I'm just being overly OCD?

BTW, I assume that 160kbps Opus is set to be the 2nd best quality in case that YouTube depreciates 256kbps AAC? (considering you apparently already have to do some fancy stuff just to retrieve it...)

Does SVPtube support actual downloading and not just streaming?  For proper ABX-ing I need both AAC and Opus downloaded.

By electronic, do you mean the equivalent of a direct recording, electronic as in synthesized, or do you mean electronic as in the actual genre?  If the latter, well, that's what happens when the majority of my test content (my own youtube "videos") don't have Opus encodings!

Again though, YouTube's AAC encoder is quite sub-par compared to non-open source encoders (like Nero AAC).

Also, regarding VLC and WMP, it's likely that WMP is using Wasapi so the 48khz is being played without resampling while in VLC it's being run through DirectSound so it's being resampled by Windows to whatever the "Default format" is set to in Control Panel -> Sound (commonly 44100hz).  Now consider that, on Windows 7, the resampling algorithm used is actually really crappy due to a bug and so there's a hotfix for it (alternatively setting 96000Hz seems to work around the issue).

Lastly, you're right about Opus being difficult to retrieve - I can't even get Opus now from that 32khz example I linked to! Update: Oh, it's because my Opus mod for CYS got over-ridden via auto-update by the current version.  Guess I should change the version number to 5.6.26.1 or something.

But that would mean the 3.3GHz 8300 would perform identically to the 4.4GHz 9370.

Also, if you're saying per-core, then technically an 83xx would be almost twice as fast because an Ivy Bridge i7 is a 4core/8thread CPU.
