I admit I am not fully getting your idea then. I want the output as same video file. If I export as images then it is just a folder with images. Yes they will be not changed, but if I want them back in a DNxHD video file, how can I guarantee that the information will be not changed due to compression? Do you mean this is possible somehow to put the images back in video file without touching the image information? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
