DV tapes aren't all the same and help with my grainy project

[zeus163]

I have a Sony digital 8 camera and generally I use the Sony branded digital 8 tapes. For xmas my pop gave me some TDK digital 8 tapes. I had planned on taking them back and replacing them with Sony tapes, but never did thinking I was just being way too anal. However, I grabbed one and recorded a band I like at a record store acoustic appearance in Seattle. When I got home I thought the colors looked grainy and not all that great. I spent some time working on the project in Premiere and then encoded with ProCoder which seems to give me the best results for other DV projects (I create DVD's from--I often capture bands on late night TV using my sony as a middle man from my digital cable box through the firewire) for DVD's.

Well, the results were very unsatisfactory. I then ran to the store, bought a Sony tape and taped some footage of my kids in the same room (light) with the TDK and Sony tapes and my wife and I felt the Sony was vastly superior.

However, I can't go back and ask this band to do another in-store appearance because it was a one off thing. Is there an avisynth script I could use for this to create my DVD compliant file that would remove some of the graininess?(I realize that there is an avisynth forum, but I wasn't sure where to put this). I have a basic script I use when I choose to use CCE to encode my avisynth scripts (does ProCoder accept avisynth scripts) which looks like this:
LoadPlugin("C:\Program Files\AviSynth2\plugins\DecombLegacy.dll")
LoadPlugin("c:\Program Files\DVD2SVCD\MPEG2Dec\Mpeg2dec.dll")
Avisource("E:\avis to work on\and you will know us by the trail of dead 9-6-02 conan\relative ways.avi")
Telecide()
BicubicResize(704,430)
AddBorders(8,25,8,25)
ResampleAudio(44100)
I'm still ironing out avisynth scripts (I'm not expert) but this one appears to work well for my TV (interlaced) captures as mentioned above (but I generally use ProCoder for these). Is there something that can be done or am I barking up the wrong tree (forum) for this?

Try something like this:
LoadPlugin("C:\Program Files\plugins\AviSynth.dll")
LoadPlugin("C:\Program Files\AviSynth2\plugins\DecombLegacy.dll")
LoadPlugin("c:\Program Files\DVD2SVCD\MPEG2Dec\Mpeg2dec.dll")
Avisource("E:\avis to work on\and you will know us by the trail of dead 9-6-02 conan\relative ways.avi")
Telecide()
Convolution3D(1, 8, 16, 8, 16, 2.8, 0)
BicubicResize(704,430)
AddBorders(8,25,8,25)
ResampleAudio(44100)
You may increase the thresholds (please refer to the readme) if there's still too much noise left.

I have no idea where the difference using different tapes comes from. Because the video is stored digitally there should be absolutely no difference between the brands. Maybe just a coincidence.

Thanks. I'll try this when I get home. I appreciate your response.

That's the thing, I don't know what is happening with the tapes. Maybe I got a bad bunch of TDK tapes. However, there is a noticable difference between the two tests my wife and I did in the same conditions. It's really strange.

Hopefully, this will make it even better!

You shouldn't be using telecide() - isn't that for film sources? I think it's better to just use fielddeinterlace().

[zeus163]

I think I tried just straight fielddeinterlace() and didn't like the results as much as I did telecide(), however, you are the now the second person who has said this to me and I will have to go back and re-do some tests.

FieldDeinterlace(blend=false)

That always looks good to me for my DV material.

Yes, correct: Telecide is not for interlaced DV sources. Use FieldDeinterlace and play with the parameters.
