The picture is only half of a BIOS tutorial. The voice has to land at the same moment as the menu on screen — and the way you record that voice, live or later, changes the whole production.
Filming the BIOS means your hands are on a keyboard and your eyes are on a monitor, while a phone records from its stand. Talking through that live is genuinely hard: one wrong menu move and the sentence collapses with it. Recording the voice afterwards is easier to control but can sound detached if it is done carelessly. This page compares both honestly and gives a working method for each, including the hybrid most tutorials quietly use.
Live narration works when the route is rehearsed and the setup is quiet. Practically, it means the phone must hear you more than the room: sit close to the phone's side of the desk or use a wired earphone microphone near your collar, keep fans and air conditioning off for the take, and speak at the screen you are showing — not two menus ahead of it. Speak in short sentences with pauses at menu changes; the pauses give the viewer time to read and give you editing points if you need to cut. The honest cost: any stumble means restarting the section, because a BIOS take cannot be patched mid-screen the way a desktop recording can.
The failure mode of voiceover is a voice describing a screen that has already changed. Short sections and notes written from the actual footage prevent it.
Film each BIOS section silently. Immediately after the section — same room, same chair, same distance to the microphone — record its narration while the steps are fresh in your mind, then shoot the next section. You get voiceover's clean delivery with live narration's accuracy, and a bad line never costs you a BIOS re-entry. For a channel workflow this is usually the sweet spot, and it is forgiving of interruptions: a doorbell ruins thirty seconds, not the afternoon.
BIOS screens are dense. When a new menu opens, give viewers two or three silent seconds to find their bearings before you speak — the same pause you would want as a viewer. Name the menu exactly as it is written on screen, then say what you are changing and why, then move. Avoid reading every line aloud; the camera already shows them. Your voice adds the route, the reason and the warnings — that is its job.
Choose live narration if the video is short, the route is simple and your room is quiet — one less production stage. Choose voiceover or the hybrid if the walkthrough is long, the settings are risky to change on camera, or your shooting space is noisy. There is no quality law here, only a matching problem: the longer and more complex the BIOS session, the more the controlled routes pay off. Whichever you pick, finish one whole video with it before judging — narration is a skill that visibly improves between video one and video three.

Watch Full VideoFor short, simple routes, live narration is faster and sounds natural. For long walkthroughs, voiceover or the hybrid method — narrating each section right after filming it — gives cleaner, more accurate results with far fewer ruined takes.
Bare walls and a distant microphone cause echo. Move closer to the mic, record in a room with soft furnishings or curtains, and keep out of the PC fan airflow. Short distance fixes more echo than any software filter.
Edit the picture first, watch each section and note what appears, then record lines section by section and place them against those moments. Give each new menu two or three seconds of silence before you start describing it.
