This is also nothing major, its barely noticeable and its mainly in the distant textures...me being a quality freek this spooks me out a bit.

Turn off Nvidia encoder, try CPU only?

+1

really?

if i go with cpu encoding is two pass and deblocking filter a good thing?

Magix AVC render quality is poor in my taste. Use Voukoder instead (set CRF between 18-20 and you will be fine).

I dont believe i have that option? VP15

You need to download and install this encoder. It is free and supports VP15.

will see to it, if it works ill keep this post up to date.

@fifonik is this software/plug in what you use to render?

Fifonik is correct that (Magix) MainConcept is less efficient at low bitrates.

For 1080p, Sony AVC is quite suitable, and x264 is even a little better at lower bitrates. Above about 12 Mbps (1080p), the three are visually indistinguishable, assuming a good sustainable minimum bitrate.

No AVC encoder is suitable for grading at anything but 8 bits. VP9 / HEVC comression, with all of its I/O processing load, is counterintuitive below 4k .

Above about 12 Mbps, the three are visually indistinguishable, assuming a good sustainable minimum bitrate.

I cannot agree. All my demos are on 20 Mbps (I'm talking about FHD, have not tried to investigate the issue with bigger frames).

It is extremely visible on some scenes (whene background is high frequency objects like leaves, grass, water) and the main object is plain (human body, road surface).

This is not the only issue for the MagixAVC encoder. Many other encoders (many moders phones affected as well) have the same issue and in some cases you can only worked it around by specifying much higher bitrate.

Sorry, I do not understand what you tried to ask.

Previously I was using x264 encodert through frameserver + MeGUI.

However, setup is complicated so when voukoder become available I tried it, compared quality and found that it is as in my previous workflow. So last few renders I did with voukoder.

You are able to use GPU acceleration in voukoder, but I'm using CPU only as resulting quality/size is better and I do not care about increased render time as all my videos are short.

Objectified results, recently posted during a similar discussion...

i must say this voukoder is quite fast, and there are alot of options avalibe

i tried to render with vokoduer and tried the vp09 codec, youtube still compresses it to avc. besides that im going to explore this vokoder alot more

@Musicvid is the lower the percentage, the better the quality?

Meaning the percents on the left are superior?

The lower percents on the left mean they are more efficient, taking up less bandwidth at the same quality.

My ancient tests put Sony AVC between Mainconcept and x264 in both efficiency and speed.

You can see the hardware encoders are less efficient because they are optimized for encode / decode speed.

"Superior" depends on your needs. So,

Size, Quality, Speed. Pick two.

quality is a must, not worried by size BUT i do upload to Youtube which means that they recommend 15mbps....so im trying to get the best bang for my buck. so what would you recommend there?

YouTube recommends 15Mbps for what resolution and frame rate? Makes a huge difference.

If you mean 1080p, I prefer x264 software codec, followed by Sony AVC. I haven't tested Voukoder vs. software for bandwidth, PSNR, or SSIM, so maybe fifonik can shed some light, in an objectified comparison of x264.

Voukoder uses ffmpeg under the hood that uses x264 encoder. I used MSU Video Quality Measurement Tool to compare my old workflow results vs voukoder results and found no any noticeable differences in size/quality when encoded with the same options (crf=21). Was not surprised as it is used the same encoder, just in different package.

Voukoder/GPU (AMD) is noticeable faster then CPU, has quite good quality (I'm using CRF target so this is not surprised me) but gives much bigger file size. As I was told that the reason -- AMD encoder in my GPU does not support B-frames.

i do upload to Youtube which means that they recommend 15mbps...

Yes, YT will always re-encode.

Sure, you can increase birtate, especially if you have fast internet connection.

@Musicvid 15mbps, im uploading 60FPS 1920x1080 gameplay
