How to re-encode mix of telecined and progressive?

[rbatty11]

OK.. can't get satisfying results here. Will there be a difference if I re-encode 4:3 vs. 16:9? I'm guessing 4:3 will yield 'better' since video portion will be.. um.. 'smaller' (in area??). Or no difference? Or should I just re-encode to 8gb and use double-layer dvd-r? Have never done a double-layer b/c of all the issues with layer break and difficulty playing on set tops. Not sure if that's still the case.

jagabo, why a short section at 8000kbps, if in the end I'll have to use 4800 or so (assuming single layer dvd-r)? I mean, what will doing that tell me?

What exactly is wrong?

Yes, assuming the same bitrate for both.

8000 kbps CBR will come close to maxing out the quality you'll get with MPEG (for DVD). That will tell you if you'll ever be happy with the results. Or if something else is going wrong. A laserdisc cap at 8000 kbps should look pretty good. CCE shouldn't have any problems with it.

If you must fit the entire video on a single layer you can resize to 352x480 -- fewer pixels per frame means less macroblocking at the same bitrate. A laserdisc source will look a little fuzzier but the reduction in macroblocking may be worth it.

Yes, macroblocking.. blurry.. faces/details look distorted. Will try the 352x480 resize, 4:3 LB then and see what it looks like. Script becomes something like this then?

loadplugin("D:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
directshowsource("F:\movie.avi")
assumetff()
telecide(guide=1)
decimate(cycle=5)
lanczosresize(352,480)
converttoyuy2()

[jagabo]

That should work -- then encode as 4:3.

One thing that occured to me: if the black borders aren't completely black, and they are noisy, they will eat up bitrate. In that case it would make sense to crop them away then addborders. That will give you pure black borders that will take hardly any bitrate away from the main picture.

[rbatty11]

Hmm, OK.. Guessing that would be like this?:

loadplugin("D:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
directshowsource("F:\movie.avi")
assumetff()
telecide(guide=1)
decimate(cycle=5)
crop(0,40,0,-48)
addborders(0,44,0,44)
lanczosresize(352,480)
converttoyuy2()

I'm curious: What happens to the 280p when resizing to half-D1 (720-352-88)? Does the player take care of that?

[jagabo]

With the DAR set to 4:3 the DVD player will display 352x480 with the same asepct ratio as 704x480. The 352x480 will be a little less clear.

Oops, wrong thread.

[rbatty11]

lol.. I see you're pretty busy!

Anyway, your suggestion to re-encode 4:3, 352x480 still stands, yes? And the script above is correct?

Yes, and yes. It's worth a try to see what you think of the results.

[rbatty11]

OK.. re-encoded/resized at 352x480 and.. to my eye, I didn't like it.. I could see too much 'fuzz' (macroblocking?).. But I have to say, the colors appeared brighter (maybe just me). Wish i could upload short clips of about 5 re-encodes I did.. but forget it.. will go with the 4:3 LB/720x480 that I did (appeared to be the 'best' to my eye). Thank you very much again for your/everyone's help. (But you know I'll be back

jagabo or anyone, would this filter Smart_Deblocking help, I'm wondering??

https://forum.videohelp.com/viewtopic.php?t=286873

Was trying to figure out how to use it in the avisynth script but don't know how, or how to figure out. The site gives this script but it's for virtualdub only??

LoadVirtualDubPlugin("...\MSU_Smart_Deblocking.vdf ","MSU_Smart_Deblocking", 0)
clip=AVISource("source.avi", false, "RGB24")
clip.ConvertToRGB32.MSU_Smart_Deblocking(1, 1, 1, 1)

Can I just put this into avisynth plugin folder? And what's with all that clip, false, rgb24, etc? I did try to read/comprehend the info on the site but didn't get very far.

[jagabo]

A deblocking filter will only help if your source has macrblocks. You shouldn't have that problem capturing from a laserdisc.

[rbatty11]

Thanks, jagabo. just found out over on the other thread, as well.

[jagabo]

Why don't you post 10 seconds of your source and 10 seconds of your results and I'll take a look at them...

[rbatty11]

I would, but I don't know how and where??

Thanks for the links. Decided just to live with the 4:3 LB conversion vs. the 16:9. In the future am wondering if a filter would help in a case like this, i.e., poor laserdisc source (i've seen laserdiscs that look horrible, like VHS quality). Would the Convolution filter help? if so, am going to have to learn how to use it.
