Dust and interlaced NTSC sources
I have been learning via this site for over 2 years now. Many thanks to all the very informative posts.
I have alot of older NTSC VHS and Hi-8 analog material that I am digitizing using the Canopus ADVC 1394. Once on the PC I am cleaning and Transcoding to MPEG2 using CCE. Most of the material has noise as some of it is almost 20 years old. The newer Hi-8 stuff is even starting to degrade after just 4 years of storage. I have used faerydust after deinterlacing and I am getting fantastic results. This has to be the best noise filter available right now. For the DVD archived stuff I would really like to keep it interlaced. The drawback to this is I can't call any version of dust twice in my scripts. The second call to the dust filter results in an output of an all black screen. I want to use the temporal capabilities of dust as it is an amazing filter. I have tried Convolution3d, but the results are no where near as good as the dust results. My question is: How do I use dust to process both the top and bottom fields independently so that the pixel locations are correct? Is there a way to process just the even fields and output that result to a HuffYUV file? Then do the same for the odd fields and then weave the two files together? Any help would be greatly appreciated! I ahve tried just separating the fields and running pixiedust and faerydust and it does improve the noisy video quite a bit, but there are Chroma artifacts that I can see in any fast motion scenes. It also seems that dust handles scene transitions quite well. Very little blurring. Thanks, Moon1234 |
