What gui program do you use for the encoder?

I have a lot of small videos of 40 seconds with 70k bitrate in mp4 format. I need to convert them to AV1 format (which would be better than webm), but I don't want to deal with ffmpeg and arguments in the console, I just want a simple and convenient interface with sliders. I have already tried Adobe Media Encoder, but it only supports webm. Are there any other video editors that support AV1?
