Pixelated text when exporting from Photoshop to MP4

[brdesigns]

Hello. I need to export a file on Photoshop to save it in MP4 format and the text layers are pixelating in the video. I searched online, and experimented with different anti-alias settings, increased my file size and dpi, didn't use any filters nor blends, adjustments, effects, nothing of the sort. This is the first time I run into this problem. I'm using the animation frames to create the video. I'm attaching one image of the sharp text on Photoshop and one of the pixelated results on the MP4. I appreciate your help.

Hi, there. I posted a question yesterday about exporting a PSD to MP4 and the text pixelating in the latter file. I tried a workaround and save the psd as a gif. Text is perfect there. So I exported it to MP4 and the text pixelated again! The file must be 864 x 288 px for an electronic panel company; when I save it with 1800 x 600 px, there's no issue with the text. Can anyone help? Thank you!
