View Full Version : Getting Good Results with Star Trek Season 1

Talk about some crappy sources are the Star Trek DVDs. THey are incredibly blurry, noisy, and interlaced. I've tried to use Autodub to create an avs file which i manually encode into virtualdub. I would just hand code the avisynth script but I'm not familiar with all the latest parameters of the functions. I've gotten marginally good results with some settings but the picture could be better. Just wondering if anyone has any good scripts for these dvds or know anything useful such as modified settings or whatever in the scripts. The problem is not with bitrate but simply cleaning the video.

I suggest you do a forum search with

avisynth noise reduction filter

I guess you will get plenty of results ;-)

DNR, 2D cleaner, Convulsion3d, temporal smoother to name a few (maybe not all appropiate, you'll have to try)

CU,

I have noticed that the star trek DVD's are mixed 24/30 fps material so I suggest playing around with decomb (decimate mode=1) and Convulsion3d. I never got it to look as good as I would have liked, they are just poor quality sources. I can post my avs if you are still interested (after I get back from work).

Mode=2 is far better, IMO. Most of each episode is 24fps native material, as such keeping it at 30fps will make it look jerky.

@JohnMK

Some people think that only heavily panned film scenes look jerky at 30fps, with the majority of the film scenes looking OK. If we accept that, one can argue that leaving it at 30fps minimizes the net jerkiness. I haven't encoded any of these, so I can't give you my own conclusion, but I can appreciate the arguments on both sides. Maybe it comes down to aesthetic tastes.

@ All:

Convulsion3d? What are you guys talking about??? ;)

Star Trek The Next Generation isn't noisy. Also, it's extremely, HIGHLY compressible. 175MB/episode is very much ideal.

@ Neuron2:

Maybe you're right. It's a matter of taste.

It is too noisy. Also blurry. It's one of the worst (season 1) DVD sources I've seen. That's what happens when you use VHS for master copies. But i do not mean that Star Trek is bad, i LOVE LOVE LOVE it. I just wish they had kept better care of it. I just think it's pretty funny that even us around this forum have more knowledge of video cleaning and archiving than the studios themselves.


Aside: DOWN WITH INTERLACING!!!

They are talking about Convolution3d. If you want to download it see AviSynth FAQ: Q20, documentation: see the threads in the AviSynth forum.
