How to grab c64 video+audio to a avi file ?
Is there a way to grab the video/sound output and
save it to a file from any of the emulators (VICE, etc) ?
(if yes, then please tell me how to do it! ;)

you need the ffmpeg dll in vice dir (on windows that is), then you can record avi from the snapshot menu. ... there should be some docs about that in the vice doc dir :) |

Another good question would be which codec to use
It would seem that a non lossy based codec would probably give great compression (where only image difference data is stored. eg static bitmap and scroller, would barely result in large file sizes |

If anyone can recommend a good alternative to the Vice capturing, i'd be very pleased to hear it. Including audio please :)
Edit: oh, and preferably 50fps. |

Right :)
Not to get too hardcore, an external capture program would be suitable.
(...i had to google for 'scanconverter', still not entirely sure what it does - but must be quite expensive ;) |

there are numerous scenarios where a non lossy compression is not such a good idea. scrolling games, or just a depacker with inc $d020 for example. |

whats the problem with capturing from vice ? converting from real machine remembers me that on one of the demo dvds even subtle but annoying noise was visible, obviously captured from real thing, with bad cabling/device :( |

capturing from the real thing *in good quality* is very hard, and indeed requires very expensive equipment (eg most, if not all, consumer capture devices will not allow to capture progressive images at 50Hz) |

Scrolling games should not be a problem as its only really the same data shifted to the left/right (and compression algo's deal with pixels in chunky form
Depacking of $d020 is not too much of a problem even with RLE etc and ultimately the non lossy would result in a crystal sharp image |

You can use a DVD recorder with the real C64.
Is quite ok. |

that will only give you 25fps/interlaced though ... wonky scrollers etc :/ |

just copy avcodec??.dll, avformat??.dll, avutil??.dll to the VICE dir, and start vice, and choose ffmpeg as encoder when grabbing. i prefer xvid.. |
