dd.create_video does not provide correct file path to ffmpeg

[spearminty]

def createVideo(args):
    ....
    image_path = f"{args.batchFolder}/({run})_%04d.png"

changing to

    image_path = f"{args.batchFolder}/{args.batch_name}({run})_%04d.png"

results in correct behavior.

Maybe i will fix this with a PR
