View Full Version : Comparing 1999 to 2003

Well, the other day I stumbled upon some OLD CD's full of fansubbed Sailor Moon episodes from way back in like '98 or '99 (long before S was licensed and released overseas, mind you). Actually, a couple of these were encoded by ErMaC (http://forum.doom9.org/member.php?s=&action=getinfo&userid=10216).
Well, this is the online fansub distro scene in '98, so we're talking hard subbed 150 kbps RVG2 encodes off of like 5th gen VHS tapes at 320x240 and 15fps. Beautiful, as you might imagine. So I started wondering how today's methods and codecs would fare in comparison. Having 3 DVDs of the S series myself, I decided to try it out.

I took a lot of liberties in this comparison. The old resolution was actually 316x236 for some odd reason. I used 320x240. In the name of advanced technology, I didn't deinterlace and half the framerate, I IVTCed and used a variable framerate based on dropped frames (dupedrop). I didn't use 5th gen vhs tapes, I used R1 DVDs :\
In addition, I didn't use .ram, I muxed the video and audio with soft subs and chapters into the best NEW format, matroska.

By that same then:now comparison logic I could have made a regular 700kbps 640x480 encode, since that's the norm now. But instead I wanted to compare how good a same resolution same bitrate file could be.

So, I took one episode and encoded it using helix producer 9.2 milestone 5 RV9 with very-high encoder complexity (85 EHQ). The video was encoded at ~132 kbps and the audio at 16.5 kbps cook-17 (stereo RA8).
That's compared to ~140 kbps RVG2 (rv2.0) with 8 kbps mono cook-0 audio.

As far as posting links to full episodes on this site goes.. well.. I'm not sure. Technically it is piracy, but it's with educational intent for comparison of old/new encoding methods.. so I don't know. I'll leave that up to the administration to remove the links if they deem it a threat. I hope not though :\

For obvious reasons, I replaced the full (25mb 24 min) videos with just the 1:52 prologue and intro. However, when cut the new encode wound up to be more than a meg larger :\ that's vbr for ya.
If anyone still wants the whole episodes PM me :P

the old:

and the new:

Check out the difference.

[edit1]hmm.. in retrospect, the old encode looks unfairly washed out and smooth for compressibility. Also I'm getting ~9 fps avg for the old encode and ~19 fps avg for mine. I'm considering redoing it with bilinear resizing and acually doing manual dup (eck..) threshold=1.0 is obviously not doing the trick if I'm getting 19fps avg on an anime like Sailor Moon :\

Still, it looks damn good for being smaller than a decent mp3.


the avisynth script:
mpeg2source("proj.d2v",idct=7)
Telecide(order=1,guide=1,blend=True,post=2,hints=true)
Decimate(mode=2,quality=3)
Deen("a3d",4,12,20,15)
clip1 = trim(16,493).crop(8,0,-4,-0).lanczosresize(320,240)
clip2 = trim(494,2699).crop(16,2,-8,0).lanczosresize(320,240)
clip3 = trim(2700,31775).crop(8,0,-4,-0).lanczosresize(320,240)
clip4 = trim(31776,34011).crop(16,0,-8,-0).lanczosresize(320,240)
clip1 + clip2 + clip3 + clip4
Deen("a3d",4,4,8,2)
dup(blend=true,threshold=1.0)

I dont think that is a good comparison (no offence meant good for trying)

I think a better comparison is if you have any fansubs done with divx 3 in 99-00 preferably before nandub.

I have a load so there must be some about.

and compare it to a fan sub today or one encoded by you with XVID or divx 5 with all the mod cons etc

That result would be interesting

plus if you could post screenshots as i dont think u are allowed to link to the whole file of copyrighted stuff. :P

Just my two bits :>

Yes, I suggest you replace the files with some screenshots ...

EDUCATIONAL LOOPHOLE :\

hmm.. I tried going the screen shot method but then I realized the two are completely off (framerate and frame number wise) and it's near impossible to find the same frames :\ Also you don't get the full effect of what a 150kbps video can be nowadays.
Damn.. legality is so messy.
If I set up an indirect link on my own homepage do you think it would be okay to keep posted?

Can't you at least link to a part of the episodes (say 500 frames)?

OK ok I'll post just the prologue and intro, though it's really the same copyright material. I love you rmeditor.exe.

8kbps for audio is torture IMHO :D

[edit]

the mkv is 2-4x better in quality.

yeah. Surprisingly, the 16kbps cook-17 sounded remarkably similar to the original.

Since it's only this 2 min sample now, I should really redo it with manual dup.
