Hey, brother, you must have encountered this situation - staring at the screen and searching every corner, but you can't find the screen recording button, right? Last week, I witnessed an old man pressing the remote control so hard that he didn’t even record the press conference. I was so anxious that I almost punctured the screen. Today I will take you to uncover the "open secrets" in this industry!

Three major pitfalls that novices must step into

Let’s start with a real case: A shopping mall was conducting a live promotion event and found that the screen recording button was malfunctioning before the show started. As a result, millions of orders were lost. When they looked for the root of the problem, they discovered that they had made these three fatal mistakes:

1. ​​Mistaking the sending card for a screen recorder​ ​(It’s like using an access card to swipe the subway)
2. ​​The software version has not been updated in three years​ ​(Pretend you didn’t see the system prompt for renewal)
3. ​​The network cable is plugged into the wrong receiving card port.​ ​(Plug the Gigabit port into a 100M line, and the speed will be directly discounted by 30%)

The most incredible thing is that a wedding company used the heat dissipation hole as a USB interface and directly burned the motherboard!

How to turn on the screen recording function correctly

Currently, mainstream devices have three startup postures:

• ​​Hardware direct recording type​ ​: Look for the physical button marked "REC" on the sending card (note that you need to press and hold it for 3 seconds)
• ​​software control school​ ​: Open the control software and look for the red circular icon
• ​​remote cloud group​ ​: There is a virtual recording button hidden in the mobile APP (you need to bind the device first)

Here comes the point! Encountering these situations indicates that it is time to upgrade:

• The recorded video has mosaics (the encoding format is outdated)
• The recording time cannot exceed 2 hours (memory chip aging)
• The sound and picture are out of sync (the processor cannot be driven)

Parameter setting anti-rollover guide

Last year, a music festival suffered from parameter settings, and the recorded material was all in slow motion. Remember these sets of golden values:

• ​​Frame rate≥30fps​ ​(The dancing figures below this are all virtual)
• ​​The code rate is set to 8-12Mbps​ ​(The highest quality of Douyin is only 6M)
• ​​H.265 encoding must be turned on​ ​(The same image quality can save half the memory)

Here’s a little trivia: High-end devices now support​ ​Pre-recording function​ ​, can automatically retain the 30 seconds of images before booting, so you no longer have to worry about missing wonderful moments.

Editor's opinion time

Let me tell you, finding the screen recording button now is like playing an escape room. But to be honest, instead of fussing with these, it is better to choose a reliable device. Pay attention to these two hard indicators:

• With dual-channel hot backup recording (the spare tire will automatically go up if the main channel is broken)
• Can directly export both horizontal and vertical formats (Douyin and Kuaishou do both)
  Recently I found that some new models support​ ​Voice control recording​ ​, just shout "Start recording screen", this is called true intelligence!

Finally, let me tell you the truth: if you encounter screen recording problems, don’t mess with it by yourself. Contact after-sales service immediately for remote guidance. After all, professional matters must be left to professionals, right?
