Frequently Asked Questions

Why is compression slow?

Media decoding and encoding is computationally intensive and runs on your device.

Will quality change?

Usually yes; inspect motion, fine detail, and audio artifacts.

Why is output not smaller?

The source may already use efficient settings or the selected output settings may be too generous.
