Convert your video files to reduce size without losing quality Yes It’s possible with StaxRip In this video tutorial you can find how it work. Enjoy!
NVIDIA GPUs (as well as Intel processors with built-in GPU and a motherboard with built-in Intel graphics) are capable of hardware-based video encoding and can drastically decrease encoding time.
Intel QSVEncC: H.264 – 2nd thru 4th generation Intel processors or H.265 – 5th & 6th (+) generation Intel processors. Click –> Intel Quick Sync explained.
My setup: NVIDIA GeForce GTX950 (Purchased for $115 US):
- 2GB 128-Bit GDDR5
- Core Clock 1127 MHz
- Boost Clock 1317 MHz
- 1 x DL-DVI-I 1 x HDMI 3 x DisplayPort 1.2
- 768 CUDA Cores
- PCI Express 3.0 x16
Computer Mainboard/Processor :
- ASUS M5A97 R2.0
- AMD FX(tm)-8320 Eight-Core Processor
StaxRip 64 setting: NVIDIA H.265 – NVIDIA (acvuvid native).
Typical x265 HEVC encode times (approximate):
60-minute 1080p video: 8 min (compared to 1.5 hours for CPU encode).
60-minute 720p video: 3 min 30 sec (compared to 35+ min for CPU encode).
45-minute 720p video: 2 min 40 sec (compared to 30+ min for CPU encode).
1080p movie x265 HEVC encode time:
Example: Star Wars – Force Awakens (2hr 18min 21 GB BDRip original) took 3.75 hours to re-encode as x265 via CPU (Intel I7 3.5GHz). Encode using the NVIDIA GPU took 10 minutes to re-encode an equivalent quality 1080p 3 GB x265.
HEVC/H.265 is the first codec efficient enough for the high-quality HD video portion of the video-audio composite file to be smaller than an accompanying 484 Kbps 5.1 audio track.
Screen grab .x264 verses .x265 (right click – save image to your computer or open image in new tab to view full-size 1280×714).
The original 720p x264 file (with AC3 384kbps 6ch audio) is 2.65GB. The re-encoded high-quality 720p x265 file (with AC3 192kbps stereo audio) is 284MB (both files are equal duration – 1 hour). The x264 screen grab is from the original file. Even though the x265 screen grab is from an additional generation video, there is very little difference between the two images.
I actually had the time to make a how to video about this: https://www.youtube.com/watch?v=3MxdsxSyW0Y
Don’t expect any magic, I just noticed afterwards that I was way too fast when changing from step to step. Thank god the pause-button exists. Might still be a lot better than only reading a long text here. So there you go!
No idea if someone even remotely discussed this topic around here, but for those who didn’t just buy their new Pascal card for games, but also wanted to use it for video encoding are probably wondering how it even works without graduating from some crazy university to get things done.
Fear not, if you figured out which program to use it’s relatively simple.
- Download and unzip StaxRip to a folder of your choice
- Download the newest version of NVEnc (3.01 as of 10/11/16)
- Unzip the file to your desktop or a place of your choice and open up this folder: “NVEnc_3.01\NVEncC\x64” and copy all of the files inside
- Go to your StaxRip folder and search for a folder with the name “NVEncC” (or simply go to “pathtostaxrip\Apps\NVEncC” and overwrite all files inside
- Open up StaxRip and pick a place where the program should store its settings. (probably the best choice is the directory you are currently working in for portable reasons)
- (somewhere in the middle StaxRip asks you to install AviSynth+, just install it, it is needed for the program to properly display video streams and work with certain file formats/codecs)
- On the right side you see your preset, which is probably set to x264. Left click on it to select the NVIDIA H.265 profile.
- Double-click on “Encoder options”
- In the new window you see variables for “Constant QP” with I, P and B. Those are for the video quality. Lower settings, such as 18 on everything, are most of the time “same quality” as I call it, but with mostly bigger filesize. You may need to experiment a bit with it, but stock settings are good as they are for solid quality and filesize.
- Now to the part with 10 bit. On the left side of the window (where “Basic” is currently active), click on “Other”. After that you type “–output-depth 10” without “” into the “Custom:” field.
- You might want consider saving your profile, so you should click the little arrow that points down next to “OK” and click “Save Profile…”. Set a name and you’re good to go! (Click “OK” afterwards to leave the Encoding Options)
- Use a file of any type and drag & drop it to StaxRip (select AviSynth+ as decoder if a window pops up), select your profile, click on “Next” at the bottom right of the program window (a job gets added to the joblist) and finally, click “Start” on the “Jobs” window.
Now the program is working and will encode your video to the same folder as the source with a “_new” at the end.
Best StaxRip Alternative For Encode H.265 Videos
