I now have 9 .eli files that contain sets of 256 repeats a single frame. Some are just 1 image, some have 2 or 3 images in the eli. I'm not greatly impressed with the quality, which doesn't seem as good as the moving picture. Tthe first .eli in particular (3 images) has a good first image, but the other two look ghosted although the .eli definitely only specifies one frame. Very odd. Anyway, I then decided to try it another way, and used lavtrans to grab a .jpg for each image that I wanted. So far so good. It looks as though they are clear images, though letter-box format, apparently stretched. I used the form lavtrans -o image01.jpg -f i -i 1810 cottingley01.avi INFO: [lavtrans] Frame 1810 grabbed At this point I came unstuck. I tried several ways: [EMAIL PROTECTED] Cottingley]$ lavtrans -f a -o coda.avi image%02d.jpg **ERROR: [lavtrans] Error opening image%02d.jpg: No such file or directory [EMAIL PROTECTED] Cottingley]$ lavtrans -f a -o coda.avi image01.jpg image02.jpg image03.jpg image04.jpg image05.jpg image06.jpg image07.jpg image08.jpg image09.jpg image11.jpg image12.jpg image13.jpg image14.jpg image15.jpg image16.jpg image17.jpg image18.jpg Unable to identify file (not a supported format - avi). jpeg2yuv says The utility you are looking for is ppmtoy4m ppmtoy4m -n 125 -F 25:1 -A 59:54 image%02.jpg **ERROR: [lavtrans] Error opening image%02djpg: No such file or directory ppmtoy4m -n 125 -r -F 25:1 -A 59:54 image01.jpg [EMAIL PROTECTED] Cottingley]$ ppmtoy4m -n 125 -r -F 25:1 -A 59:54 image01.jpg INFO: [ppmtoy4m] Command-line Parameters: INFO: [ppmtoy4m] framerate: 25:1 INFO: [ppmtoy4m] pixel aspect ratio: 59:54 INFO: [ppmtoy4m] interlace: none/progressive INFO: [ppmtoy4m] starting frame: 0 INFO: [ppmtoy4m] # of frames: 125, repeat last frame until done INFO: [ppmtoy4m] chroma subsampling: 4:2:0, JPEG/MPEG-1, interstitial siting **ERROR: [ppmtoy4m] Bad Raw PPM magic! So then I tried to put together a command for jpeg-yuv, like this jpeg2yuv -f 25 -I p -L 1 -j image%02.jpg but there doesn't seem to be an output filename? The aim is to creat a file that can be concatenated to the main video, to give a better ending. The main video lasts around half an hour. I am trying to make the images display for around 5 seconds each and was hoping to get a 1 second transition on them, but I don't seem to be able to understand what is needed to pull everything together. I need a prod in the right direction, please.
