Re-encoding the video reduced the gaps, can someone give me directions to move further?

ffmpeg -i ~/Downloads/600_/600_1080p60.ts -c:v libx264 -c:a aac -strict -2 ~/Downloads/600_/fixed_output_reencoded.ts

ccextractor ~/Downloads/600_/fixed_output_reencoded.ts -o output.srt --fixpadding --fixptsjumps (works just as fine without padding n pts jump options)
