best settings

[mrmorg]

Hi whats the best settings for encoding US TV shows?
original files are 720p 1.6Gb / some 1080p 2.5Gb
I currently have the video tab set to;
Preset : Ultrafast, Tune: Off
Single Pass, Ratefactor-based : value 20.0
pass throu audio and picture res same as original.

Just doing a 1080p, 55min show now and it says it will take 36mins @36fps
this is running on my Server, Dual Xeons 48Gb Ram 21Tb Raid.

anyone know of the standard settings? i want the identical quality of the x264 original but in x265 wrapper , saving space.

You really just have to play around with the settings until you get it
right, or learn how to compare x264 with x265.

That and you can give my Encoding Preset a go: Extreme 1080p Encoding

does the preset make any difference apart from the length of time it takes???

[thefinaldegree]

The presets (fast, slow, medium, etc) change how much effort it puts into
compression, while aiming for the Bitrate or quality

many thanks

for anime i put preset on faster, crf 23-25 for 1080p video quality is v.good
for example source file 1,5GB go to 125-250MB (24min video) (get 95-98% of its quality)
time to encode depends of computer
amd fx6300 oc from 3500 to 4300 take it in 40min
i7 6700k on stock (using option for Intel in settings) take 13-14 min

I don't change any normal video so far but think crf 20 will be good (maybe I will put preset on medium)
to take almost the same quality

I use 21 for high definition videos like tv series or movies.
23-25 for anime or average quality stuff like online videos, youtube rips etc. i think quality is acceptable and time it takes is reasonable. also cartoons don't have that much detail so 23 feels like 20 but encodes faster. I would like to use slow preset by default but i find it ridiculously slow… beside, if you don't encode HD stuff, hevc kind of struggles on parallelization due to lesser rows. for example, when i encode stuff around 320p or below even if it sees 50fps, it just won't saturate all 8 cores, in times like this i run handbrake(cli) and ifme at the same time. it doesn't really matter medium or slow preset, it just can't parallelize nonhd content(it is not designed for them anyway). I don't like to go all the way to slow preset but sometimes when i really worry about quality, i set it to crf 20 and use me=2, it does slow down a bit but not as much as slow preset. for most part, i try to catch 60% bitrate if convert from avc, about 20-40% for mpeg and divx. so far i didn't convert anything from raw/uncompressed source. cores are useful above around 720p but if you go lower, it depends on clock speed rather than settings and cores. but fullhd and above lets you experience the relation between speed and settings. with something like 5ghz avx2 8 core cpu, i would use slow or slower preset with crf 20. i dunno maybe i would even choose 15 for hq stuff but i don't want to fall below ~10fps.

which are the settings for a movie in B/N PAL 720x576 (DVD)?
I did the coding with this profile "Extreme 1080p Encoding" but the result I do not like,
the definition is not the greatest
the original file was 4 GB and then and become 700 mb

[thefinaldegree]

That is meant to encode HD things mainly, if you're using an SD source then I suggest loading the preset then adjust the rate factor to a lower number. You'll see an increase in file size but the quality will also increase. Just please be aware that a DVD rip is a lossy source and a such you won't see much improvement. If you can, I'd suggest finding a BluRay source.

hi thefinaldegree
I have many rip DVD (vob), 4, 6, 9 GB
I would like to lower the size but maintaining the quality

what are the correct settings for the DVD?

[Alexisback]

for these DVDs there is no Blu-ray

[thefinaldegree]

There's no "correct" setting for any media, but more like how much quality do you wish to lose/keep verses how large of a file/how long it'll take to encode. If you follow my advise in my previous comment, then you'll be able to tweak the quality to your liking. (Again, the quality won't be better than the source video you're using) On Wed, Apr 5, 2017, 10:37 PM Alexisback <notifications@github.com> wrote: hi thefinaldegree I have many rip DVD (vob), 4, 6, 9 GB I would like to lower the size but maintaining the quality what are the correct settings for the DVD? — You are receiving this because you commented.
