I was browsing the net looking for suggestions on how to get the best DIY conversion / clean up from VHS to DVD when I came across this post -
One of the suggestions is that more than one copy of the recording (by which I assume he means the tape or two tapes are captured as uncompressed digital video files) are aligned so that noise / artifacts can be eliminated. I am particularly interested in the idea of taking multiple copies / tapes to generate a "best output".
Does any one know whether this really works? It it a matter of simply mixing the two streams together or using special software with a filter that takes the frame from the copy of the file that it deams best quality for each frame for the output?
If there is such software / filter, does the technique have a name that I can google to find out more?
Thanks for any suggestions.
In my opinion, the best way to get VHS converted is to record direct-to-disk, either by way of a DVD recorder or video capture card onto a hard drive. Depending on whether you use PC or Mac, just about any good quality editing software will make it possible to improve the clarity of your video. Because VHS is analog, unfortunately whatever is there is about as good as you're going to get. Since I am a PC type, my editors of choice are Adobe Premiere and Vegas, although I will use a Ulead product once in a while for those quick projects. They have built-in filters that will enable you to enhance your work. In my experience, the multi-image process can be frustrating because only one track will be visible in the timeline. Play around with some of your color correction and sharpening controls. Good luck!
Thanks for the comments.
I must admit that I'm more curious about the algorithm and whether that kind of processing / filtering of multiple copies to take the best frame (thinking about it more - parts of frames to create 1 output frame) already existed and I just didn't know about it.
I have just copied a tape onto DVD. The original tape is poor quality and I only have 1 copy so there's not much I can do except eliminate noise caused by the conversion process which I doubt if I would notice anyway.
One suggestion from that original thread that I did try was to add a thin black border. This hides the noise around the image edges and really does make a difference.
I'll try your suggestion of copying from video straight to a DVD recorder. (I used my Canon Camcorder AVin to DV out conversion mode to capture DV in Pinnacle Studio, added the border and author to DVD.)
