Premiere Elements 2025 - Export

I record videos on my canon compact camera with these settings – FHD, 1920 x 1080, 50 frames per second and I edit them in Adobe Premier Elements 2025.

Using Elements 2024, I used to export them as HD movies. But the export in Elements 2025 has changed and I’m confused about which is the best export option for me.

I upload the movies to YouTube, but I don’t like to directly upload to YouTube, I’m not sure why, just a bit nervous about that, so I save a copy on my PC first and then upload to YouTube.

The export – “Computer” option defaults to H.264 and Match Source, but this exports an SD, 1280 x 720, 29.97 fps, movie. I have looked at the YouTube option and that seems to do the same (although I’ve not literally exported to YouTube). I’m puzzled that it says Match Source but then exports differently?

Curiously though, the movies look the same quality in YouTube as the ones I previously loaded in HD when using Premier Elements 2024, so that’s good.

So, my questions are, why does the Match Source option not match the source files and ideally what settings should I used to get the best quality for YouTube?
