I'm not certain about this, but I believe that RAWFRAMES is only meaningful for the "Storyboard" Input Mode, and then only if the source video file includes valid JPEG frames in its format (i.e., MPEG1 I-frames, or MJPEG). For these formats, rather than decode the (JPEG) frame into an image and then encode that image back to a JPEG file, the video encoder will simply extract the JPEG frame from the video stream. This is beneficial from both a speed and quality perspective. If you are not in "Storyboard" Input Mode, encoding is mandated regardless of whether you use RAWFRAMES or SINGLEFRAMES. _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
