Dave,<br>For *micro sd* card, the limits are<br>* the card itself<br>* the reader, usb3 being much better (many built-in card reader are not even usb2). Much better are the SD readers with real micro SD slot (I have one). <br>Else, one have to use better recordings medium, like Atomos devices with ssd. But there recording format is prores or dnxhd 50 gb an hour 😫 (I also have one). <br>The computer is not faulty. I have 16 gb ram and kdenlive do not use it well. If you only have to cut pieces, avidemux3 in copy mode is OK, but to really edit you need DaVinci Resolve (the free version is stunning) <br>Jdd<br><br>-- <br>Envoyé de mon appareil Android avec Courriel K-9 Mail.
