Do you have to turn your video into an image sequence for a specific
reason? You should be able to use the drawtext filter to add text to your
image. You should choose a lossless codec such as ffv1 in order to preserve
the quality of your original video, minus your superimposed image.
It might help if you post whatever attempts you've tried thus far with the
full uncut console output.
