Lossless HuffYUV with ATI MMC
And I'll have an OJ with that :D
I've been lurking on here for a while now. I have an All in Wonder Pro and have been using Virtualdub to capture Lossless HuffYUV from my old Videos. But I really dislike the program interface :question: and would rather use the software that came with the card (Multimedia Centre). I have already used this to capture mpeg and find the interface MUCH more enjoyable :) I think one of your own, Lord Smurf, wrote the following guide to capture lossless huffyuv in MMC: http://www.digitalfaq.com/guides/vid...re-ati-avi.htm Would capturing this way provide a higher quality video than capturing mpeg using the same card? Once captured I would filter and edit before encoding to mpeg to put onto DVD. Thanks for any advice. Tony. |
Of course if you intend to filter or do other restorative work on a capture, you wouldn't want to capture to lossy MPEG in the first place.
Using MMC to capture YUY2 huffyuv AVI, you'll get exactly the same results you'd get using Virtualdub to capture the same way -- however, with MMC's interface you lose the ability to monitor for valid video levels. I assume that you understand the importance of capturing at legal luma levels. http://www.digitalfaq.com/forum/vide...st45238http:// . I'd also assume that you've been monitoring and adjusting signal levels all along. The above link is one part of a more recent VDub capture guide that begins here, if you haven't seen it: http://www.digitalfaq.com/forum/vide...-settings.html Use whatever you want, but be aware of certain elements that affect your capture and all subsequent work. |
Minor Editing
Quote:
Really just minor editing (trimming the ends off tapes that have tv programs at the end of them and also rarely padding if there is excessive noise) so nothing elaborate. 'Filtering' was probably the wrong terminology to use. I've used Womble in the past. But I read somewhere that capturing in hufyuv avi and then encoding to mpeg slowly afterwards results in a better quality mpeg file and hence a better quality DVD. |

Whether you get quality improvement by capturing to lossless and then encoding separately is a matter of how you're encoding. If you're encoding lossless to MPEG using the same or similar settings you use if you captured to MPEG in the first place, you'll see very little improvement without cleanup. For archival purposes, another advantage of lossless capture is that you can separately encode an archive copy at very high bitrates, much higher than you could use for DVD or web posting. |
As is works fine for us :-)

Yeah I know Virtualdub can do all that but I can never tell if anything needs doing or not. In other words my eye for visual detail is limited. All I know is that the family is very happy with what I've done so far and that is good enough for me :congrats: Will let them know about your last sentence though as that is certainly a very good option if they want to filter the files themselves now or in the future. Thanks Sanlyn. Appreciate the way you help lots of people :) |
