I'm using FFMPEG to merge an equirectangular image with an equirectangular video. The image is scaled to fit the video, and then I need to adjust the rotation of the image by 90 degrees so I cut 25% off the left and put it on the right.

THe problem is the width is extending to 3458 with this process and I'm getting a black line down the edge.

[1:v]scale=3456:1728[hs11];

[hs11]colorkey=0x00ff00:0.9:0.1[hs12];

[hs12]split=2[hs1l][hs1r];

[hs1l]crop=out_w=864:out_h=1728:x=0:y=0[hs1lx];

[hs1r]crop=out_w=2592:out_h=1728:x=864:y=0[hs1rx];

[hs1rx][hs1lx]hstack=inputs=2[hs13];

Here is the command for this part with Fluent FFMPEG

  filter.push({filter: 'scale', options: `${width}:${height}`, inputs: `[${index+1}:v]`, outputs: `[hs${index+1}1]`})

  filter.push({filter: 'colorkey', options: '0x00ff00:0.8:0.1', inputs: `[hs${index+1}1]`, outputs: `[hs${index+1}2]`})

  filter.push({filter: 'split',options: '2', inputs: `[hs${index+1}2]`, outputs: [`[hs${index+1}l]`,`[hs${index+1}r]`]})

  filter.push({filter: 'crop',options: {out_w: width * 0.25, out_h: height, x: 0, y: 0}, inputs: `[hs${index+1}l]`, outputs: `[hs${index+1}lx]`})

  filter.push({filter: 'crop',options: {out_w: width * 0.75, out_h: height, x: width * 0.25, y: 0}, inputs:`[hs${index+1}r]`, outputs: `[hs${index+1}rx]`})

  filter.push({filter: 'hstack',options: {inputs : 2}, inputs: [ `[hs${index+1}rx]`, `[hs${index+1}lx]`], outputs: `[hs${index+1}3]`})

  filter.push({filter: 'overlay', options: {enable: `between(t,${options.start},${options.end})`}, inputs: [init,`[hs${index+1}3]`], outputs: `[hs${index+1}x]`})

Here is one of the images I'm adjusting.

I'm trying to get that text into the centre hence cutting 25% off one side and putting it on the other side.

This would probably be better done with a remap filter but I'm not sure how to use that.
