qencoder 2.1.4

Qt graphical interface for encoding

Cross platform video encoding gui

Encoding video is slow. qencoder makes it fast!

The most efficient av1 and vp9/vp8 encoders do not scale very well across lots of cpu cores. By intelligently splitting the video into multiple chunks, qencoder allows you encode better videos than with svt in much less time. qencoder is inspired by and uses code from Av1an, while delivering a more familiar gui experience for Windows and Linux.

Simple and easy to use

You don't need to have a deep understanding of how video works to take advantage of qencoder. With extremely easy to use and powerful presets, qencoder is for everyone.

Powerful for those who need it

qencoder features many useful features which make it a powerful tool. With scene based splitting, qencoder is the first ever gui to take advantage of systems with hundreds of cores. By splitting at the right moments, qencoder ensures your videos do not have any overhead from unneeded keyframes.

It also is the first gui capable of boosting dark scenes. Allowing you to use lower q values to avoid nasty artifacts like banding when needed.

It allows you to configure the colorspace of both your input and output, to ensure that your hdr video stays hdr.

Finally, it supports minimal splitting, the ideal mode for 2 pass vbr encodes. This mode makes as few splits as possible, keeping them all as far apart as possible so that the bitrate stays as variable as possible.

Video queueing

qencoder is the first gui av1 encoder to support proper video queueing. Setup the perfect encode for your video and add it to a queue. Repeat for as many videos as you want to encode. When you are done, save the queue to a file for later, or run it now with the encode button. If any videos are in the queue, qencoder will encode them.

Per Scene Encoding

Per SCENE encoding, analogous to automatic per title encoding, lets you optimize your encodes to save space. Each scene can be encoded to target a specific vmaf (perceptual visual quality). Don't pay a cloud company to optimize your encodes, qencoder lets you do it all in house.

Free codecs

qencoder supports free codecs that can be encoded into webm. This means your videos can be shared and played on any html5 compliant browser. It also means that you do not need to worry about licensing fees or patent violation using it. Your encodes are yours, and should stay that way.

Using qencoder

Windows

Download the latest 7zip in the "releases" section.

Linux

Ubuntu:

Via pip:

First, install ffmpeg, an up to date version of aomenc, and an up to date version of vpxenc. Then install qencoder.

sudo apt update
sudo apt install python-pip vpx-tools aom-tools ffmpeg
pip install qencoder

Arch:

It's recommended that you install it from the aur:

https://aur.archlinux.org/packages/qencoder/

Others/Manual installation:

Git clone this repository:

git clone https://github.com/natis1/qencoder

cd qencoder

Then install ffmpeg and an up-to-date version of the aom encoder (for instance aomenc-git, on arch)

Then install the python requirements:

pip install -r requirements.txt

Then run it with

./qenc.py
