| [edit] APNG mod is ready, I'll release it soon. Works similar to File -> Export -> Animated GIF, but Animated PNG is lossless, truecolor, with optional alpha channel. I started with libpng, but got rid of it. The build still uses zlib, though. |

| The apng mod build is based on 1.9.2 code, so I'll release it as soon as 1.9.2 goes final. |

Check this out: Steps I used to create it: 1. Tools -> Create test video 2. Add Filter -> 2:1 reduction, with alpha channel 2. Add Filter -> motion blur with alpha channel 3. Cropping (128,48,128,48) 4. Video -> Frame Rate -> Change to 20 fps 5. Select range (40,140) 6. File -> Export -> Animated PNG |

| "File information" working with photo images -- that's great! Really. |

| Is APNG the same thing than born-dead MNG animation format or is it a new one ? How VDub APNG Mod handles APNG files : does it load all the content in memory or does it read like a streaming file ? Because i tried to load a HUGE mng (a 336 MB video capture from M.A.M.E. emulator), and after hard disk access during a few minutes, i got an error message like "File is not a valid PNG". I know this mng file is valid since i could extract all the frames in separate png images. Is there any chance to see MNG support added to your mod ? Thanks |

| APNG is different from MNG. This mod only supports APNG. I thought about MNG, but the application support for that format is not that great. I tried official gif2mng converter, and it refuses to work. I tried "export to mng" feature in GIMP, and it crashes. Maybe that MAME emulator is the only mainstream software that still produces MNG. MNG is pretty complex, but if MAME produces only simple stuff, like maybe just full-frames and nothing fancy, then import wouldn't be hard to implement. Edit: Indeed it's the case. Implementing simple mng loader was pretty easy, it works fine, so wait for the new Mod version. |

| Here you go, the version 1.9.6.1 can load MNG files. http://vdubapngmod.sourceforge.net/ P.S. Also, in my mod you can use transparent PNG in logo filter. |

| You have read in my mind, my MNG files are game captures from MAME. Great work, thanks for adding MNG support, il will greatly simplify my conversions  |
