Pixelated render/animation

My objects are very pixelated after rendering, also when i export a video of the animation the quality is really bad. I’ve tried bringing the resolution up to 200% but it still was bad.

this is what the render looks like:

Also how to export the video with transparent background only the particles. I made the film transparent and exported with FFmpeg video codec #1 but it’s still black.

Difficult to say as this… roll your mouse wheel over the render windows… or export a little part of your scene to share it that people could investigate here…

ps: In general, the best usage is to render lossless images with alpha (so you can resume your render where you want for example or re-render certain animation parts ) and make a video in blender VSE or another editing software.

After changing the output properties to what you send the video exported with perfect quality. Thank you very much!

But unfortunately other problem occurred. At some frames the particles glitch and go all over the place when i try to export a longer video (10-15sec)
