Save 4k videos on a bad MicroSD?

I have a GoPro Hero 8. For 4K videos, it says my Micro SD needs at least V30 and UHS Speed ​​Class 3. If I record my GoPro video with this SD card, and then save the recorded video afterwards to a Micro SD with, for example, V10 and U1 and then export it from there for editing, will the video still have 4K resolution?

I could always scream for pleasure when I look at how much money is spent on high-quality cameras and travels and then is saved on something like the memory card. Remember that if they are cheap, they may have been removed from production because they have not met the high quality requirements for a brand card. Is that when something goes wrong? The old saying that a chain is only as strong as its weakest member is still valid.

In short, put a reasonable card of a brand manufacturer to the warranty, if necessary, forty years. It doesn’t matter if something goes wrong, but you can rely on the manufacturer of these cards to have quality management and to be sold only top cards under this label. Rather, if you have decided to run for two or three manufacturers and card sizes, it will be possible to run through an price search engine.

The quality does not change due to copying to a “bad” SD card, the data are copied to digital data carriers 1:1 without loss.

The difference between the different speed classes is, as the name says, only the speed. The card in the camera must be fast enough to store the data in real time. If the camera records in 4K at a bit rate of, for example, 150Mbit/s, the card must also be able to store the data at this speed.

If you now, let’s say, have a 10 minutes long 4K video on a map and copy it to a slower map, it can be that copying takes 20 minutes, i.e. significantly longer than the video itself. This is not a problem with a video that already exists, except that you have to wait longer. You couldn’t take the camera directly on the map.

Quality does not change when recopying. You only need the card during the recording because a slower card can not store the amount of data that arises at high resolution so quickly.
