Short: Browse & Repair VLab YUVN sequences Author: alexander.richter@01019freenet.de (Alexander Richter) Uploader: alexander richter 01019freenet de (Alexander Richter) Type: gfx/show Version: 1.0 Architecture: m68k-amigaos See also: FPSCon: decreases the framerate of frame sequences ReNumber: gives frame sequences a continuous numbering The VLab-Y/C video digitizer board sometimes produces faulty pictures (e.g. wrong horizontal and/or vertical offset). That's where YBrowse comes in. It's a grayscale thumbnail browser for YUVN frame sequences. YBrowse has benn written very quickly. It's not an application, it's just a very tiny program. Actually, to write this readme took more time than to program YBrowse... so don't expect too much. Also, YBrowse does not use the official libraries to access IFF-YUVN image data. INSTALLATION: Just copy "ybrowse" to your C: directory. HOW DOES IT WORK? YBrowse lets you click on faulty pictures, which will then be erased from the screen. On exit, YBrowse writes a file named "script" into the current directory. If you execute this file ("execute script"), all faulty pictures will be deleted and replaced by their predecessor. START: YBrowse must be launched from CLI. CD into the directory that contains the pictures. Then type: "YBrowse " where stands for the number of the first frame, stands for the number of the last frame and stands for the base name. Example: the directory contains the frames frame.0000, frame.0001, ... etc., ... frame.2345. In this case, you would have to type: "YBrowse 0000 2345 frame." USAGE: YBrowse opens a 16-grayscale-screen (i.e. runs on OCS, too) and shows 6 thumbnailed pix on that screen. If all the 6 frames are ok, press the right mouse button to see the next 6 frames. If you discover a faulty frame, click the frame with the left mouse button. It will then disappear. When you're done, and the pro- gram exits, just type "execute script" in the CLI. HOW TO QUIT: You may leave the program any time by clicking into the rectangle area at the bottom of the screen. Don't forget to "execute script" if you've clicked faulty pictures. HINT: Delete the file "script" ASAP if you don't need it anymore. Other programs may interpret it as part of the frame sequence.
