Frequently asked questions
Will the resolution drop?
Only if the math requires it: short clips at generous caps keep full resolution. The strategy line in the result tells you the bitrate and resolution used — no silent surprises.
Why two-pass encoding?
Pass one analyzes where the bits matter (motion, detail); pass two spends the exact budget there. Single-pass encodes either overshoot the cap or starve complex scenes.
What about the audio?
Audio is re-encoded to a lean 128 kbps AAC — transparent for voice and acceptable for music — and its share is deducted from the video budget.

Share a link — re-compression always costs some quality.
