FFmpeg converting to .265 corrupts videos - react-native

Question

I'm trying to convert and compress videos in React Native using FFmpegKit, what is strange is it is very slow regardless of the preset I use, Also, no matter how big the input video is, it always produces a video less than 1MB that is corrupt.
This is my first time using FFmpeg, I'm using it due to the lack of good video compressing libraries on React Native.
My command looks like this:
const getFFmpegCommand = (input: string, output: string) => {
const scale = `"scale='if(gte(iw,ih),min(720,iw),-2):if(lt(iw,ih),min(720,ih),-2)'"`;
const preset = '-preset veryfast ';
const ffmpegCommand = `-i ${input} -y -crf 28 -vf ${scale} ${preset} -c:v libx265 ${output}`;
return ffmpegCommand;
};
This is my log output
