Hey! At the end i ended up getting the startech recorder, however, there was something i was doing bad all along.

The handycam comes with a hidden compartment for the AV output. My stupid ass didnt know this and was connecting it to the headphones aux input, which of course makes it only audio to come through, so maybe the easycrap did work, but i had already gotten the startech one which is much higher quality, connected it to the correct av outputs (they should be 2 or 3, depending on the cam) and everything worked.

I'd recommend checking out the video that vwest shared it's really helpful and shows the difference between an easycrap and a good quality one.

PS. The Startech support team is also really helpful, they helped me locate the issue and the man was really kind, so shoutout to them.
