Do you skip recording a wish because you fear a few minutes of video will eat your whole data allowance or heat up your phone? Standard 4K or Full HD video can weigh hundreds of megabytes. The good news is that wishes don't have to be long or heavy, and preparing a recording takes only a few minutes.
This guide shows how much data a recording really uses, how not to overload your phone, what to do when the upload fails, and how to frame the shot so it looks good on the recipient's screen.
How much data a recording uses
In the browser the phone records video at about 800 kb/s and sound at about 64 kb/s. That is about 6.5 MB per minute. Wishes last from 10 to 30 seconds, so a single recording is usually a few megabytes.
Full HD video shot with a regular camera takes many times more space and data. If your data plan is limited, you can upload when you are on Wi-Fi. It isn't necessary, but it is convenient.
Why a short recording saves the battery
Long recordings load the processor and the battery, and the phone gets warm. That is why wishes are short: the song “Sto lat” lasts about 20 seconds, and wishes up to 30 seconds.
While recording, the browser sends data every 5 seconds instead of keeping one huge file in memory. Only when the recording ends does the whole thing go to the server. The phone doesn't have to carry a large buffer, and a short interruption doesn't erase what has already been saved.
What to do when the upload fails
Weak signal in a lift or on a train happens to everyone. The app retries the upload automatically, with pauses of 2, 4 and 8 seconds. If that isn't enough, the recording stays on the screen and the “Try again” button sends it once more.
Don't record again in that case, because that only adds time pressure. Wait until the connection comes back and try again.
10 tips before you record
- Light in front of you. Sit facing a window. Light from the side or behind darkens the face.
- Phone in portrait. The film is made in portrait, so record the way you will watch it.
- A steady support. Lean the phone on a mug, a book or a stand. Your hand shakes; a table doesn't.
- A quiet room. Switch off the TV, music and fan. The phone's microphone hears everything.
- Speak naturally at arm's length. Don't bring the phone to your mouth, or the sound will clip.
- One sentence as a test. Record a short test, listen back, and check the voice and the light.
- Prepare the thought, not the script. Three words in your head are enough. Reading from a card is audible at once.
- Close other apps. Fewer background processes mean smoother video.
- Silence notifications. A text-message sound in the middle of a wish spoils the whole clip.
- Don't be afraid of a retake. You can record several times and choose the best take.
What the organiser receives
Every recording goes to the server, where it is converted into one common MP4 format (H.264 video and AAC audio). You don't have to choose a format or install anything. When the film is assembled, all clips are matched to one resolution, portrait 1080 × 1920, and the volume is evened out.
That way the film plays on an iPhone, on Android and on a computer, and the organiser doesn't have to guess which format is right.
Summary
A light format, short recordings and automatic retries make recording a wish on a phone simple. You need good light, a steady setup and one test take before the real one. You collect everyone's wishes in one place, without sending videos through messengers.
