I hear ya, but you and I know that bandwidth = money. Hence all the interest in HEVC and vp9 lately.............
Got my retirement plans all set. Looks like I only have to work another 5 years after I die........ -
This thread was not created to bash x265-encoder or promote divx265 my goal was to help people to find best encoder for hevc . comment like this doesn't help anyone please when you claim something provide evidence for it . divx265 quality in same encoding time is better than x265 in low bitrates and my comparison test between x265 and divx265 show that .Originally Posted by racer-x

I didn't post to this thread to bash Divx265, I was just making an observation. I used your GUI, but unfortunately it only works in Bitrate Mode and the quality suffered. When I encoded with the CLI, I used -qp 25 -aqo 3. That greatly improved the quality to the point where it was hard to tell them apart.Originally Posted by david55

Author of the GUI need include DXVA2 for ffmpeg (more performance)

should be optional since:Author of the GUI need include DXVA2 for ffmpeg (more performance)
a. it crashes on some systems
b. is slower than normal processing on others
-> not always a wise idea to enable it -
Comparison between divx265 and x264
x264
resolutions 720p
profile slow
bitrate 400kb
Encoding time 6:20 min
Size 15.5 MB
Far less quality compared to " divx265 1.2.0.24 fast and 1.3.74 fast "
download x264 slow 6.20.mkv
x264
resolutions 720p
profile very slow
bitrate 400kb
Encoding time 15:30 min
Size 15.5 MB
Far less quality compared to " divx265 1.2.0.24 fast and 1.3.74 fast"
download x264 very slow 15.30.mkv -
And this statement is based on what?Ultra-low bitrates are the only real reason to use an HEVC encoder anyway.........
-
It's based on my observation that AVC currently outperforms HEVC everywhere quality wise, except very low bitrates. That may change as hevc develops.

Hi david55,
Make comparisons DivX_v1.2.0.24 vs DivX_v1.3.74 only this time the balance mode? -
Comparison between divx265 1.3.74 balanced and divx265 1.2.0.24 balanced
divx265 1.3.74
resolutions 720p
profile balanced
bitrate 400kb
Encoding time 5:30 min
Size 17.7 MB
less quality compared to " divx265 1.2.0.24 fast "
download divx265 1.3.74 balanced 5.30.mkv
divx265 1.2.0.24
resolutions 720p
profile balanced
bitrate 400kb
Encoding time 18 min
Size 17.7 MB
almost same quality as " divx265 1.2.0.24 fast "
download divx265 1.2.0.24 balanced 18 .mkv -
DivX265 v1.2.0.24 /abr/balanced > download (2.1 mb)
Finished after 1:36 min
Long encodes and worse quality.
DivX265 v1.3.74 /abr/balanced > download (2 mb)
Finished after 0:26 min
Quickly encodes and better quality.

@david55,
You have not enabled colorspace properties: -709 (so different textures). -
You encoded with CLI or with GUI ?Originally Posted by Gravitator

I did a small test... For the speed, Divx265 gives good quality...
So it for fast encodes, and users who like it fast... Even the slowest -aqo 4 is pretty fast!..
But I like the slower x265... Since even though it is slow, it gives better quality...
I hope Divx265 will add extra presets with that is slow expanding it's range...

I want to look at more psy improvements with a 2-pass
