Strengths & Limitations
Strengths
- +Comprehensive comparison of multiple popular encoders.
- +Inclusion of various presets to reflect real-world usage.

Limitations
It can be difficult to accurately measure the exact energy consumption of software on a personal computer, and the carbon footprint depends heavily on the local electricity source.
Reliability & validity
Reliability could be enhanced by repeating tests multiple times and averaging results. Validity is supported by using objective quality metrics and a standardized dataset, though the specific energy mix of the server location limits generalizability.

Paragraph starter
This research highlights that the choice of video encoder and its operational preset significantly influences energy consumption and carbon emissions. For instance, the x264 encoder at faster presets was found to be highly energy-efficient, producing minimal CO2 emissions. Conversely, slower presets on encoders like SVT-AV1, while offering better compression, resulted in substantially higher energy demands. This underscores the importance of considering software-level optimizations for environmental sustainability in digital design projects.
