Second Reality good video capture?
category: offtopic [glöplog]
I am so ready for this capture.
Uploaded hfr's capture (with fixed aspect ratio) to youtube:

hfr: you may want to update the file in your ftp with this one:
http://mrdoob.com/files/temp/future_crew-second_reality.mp4
Using MP4Box I've changed the pixel aspect ratio in the video so it displays in 4:3 (no recompression or anything).
trixter: looking forward to see what you get :)

Maybe you won't -- I've opted to go with the SB output because it is more accurate (listen to the notes in the "10 seconds to transmission" part in both SB mono and GUS for a comparison). I looked back at MC1 and I used the GUS output there and could hear the same loose timing -- damnit.
Remember, my goal is to create a version that people could burn to blu-ray. That includes re-timing and re-framing some sections; it also involves frame dropping as well as frame-synthesis. I fully expect half of all sceners to really hate my version.

Mr.doob : keep in mind that Youtube caps videos at 30fps.
The plasma section is the trickiest. If you can't make a proper video that has the same fps than the source and at least twice the resolution, you're f**ked.
When I captured Second Reality for TV a few years ago, I had to specifically postprocess this part in After Effets, in its original resolution, in order to make a 50/50% blend of each frame with the following one (which actually renders the effect as it was intended to look). Of course that was also because broadcast videos have limitations, the biggest one being interlacing, which does not cope well with that kind of effects.
But technically speaking, it's not the original effect anymore.
For SR DOSbox capture mode does a pretty good job, but the only thing is that you get a lot of small videos with different resolutions and framerates as you found out.
Some other demos don't work correctly in DOSbox because of video sync issues, like Crystal Dream II or Act1.

rickst: I found the plasma thing out when I did MC1 -- I solved it the same way you did but in hardware (filtering option on the scan converter). The video I'm working on tonight does not do that though -- it's all preserved. Hopefully I'll finish it tonight.
Well, that took much longer than it should have. I decided to just go ahead and give it the full damn treatment. Pick up the video and .nfo file from ftp://ftp.mindcandydvd.com/pub/MindCandy/Volume_3/extras. Gloom, hope this is what you were expecting...

This video of Second Reality by Future Crew was captured and edited for Blu-ray
in the same manner as I would have done for a MindCandy Blu-ray release. My
goal for all DOS-era demos is to present them with a mixture of realism as well
as present them in the best possible light. This means I take liberties with
the demo, sometimes reframing or retiming various parts. This also means I
sometimes fix bugs in the original demo during the edit. If you don't agree
with this, well then, You Have Been Warned.
I fully expect half of all sceners to really hate this edit. That's okay;
there are other dumps on youtube, etc. if you disagree with this one. I myself
believe that you should run Second Reality on a 486/33 with an SBPro and a 14"
VGA CRT tube if you really want to see the best version of Second Reality.
The file SecondRealityHD.ts is a 1280x720 @ 60p MPEG-4 transport stream in
Blu-ray format (muxing), ready to burn to blu-ray if you so choose.
=====
List of global changes I made for this edit:
All 320x200 full-screen sequences were adjusted for aspect ratio (so that
circles look like circles instead of ovals). Also, the SBPro output was used
as the audio track (and pitch corrected to match SBmono/GUS pitch) for several
reasons: The timing is tighter than GUS; it was the soundtrack the audience
heard at ASM '93; it was the soundcard that Purple Motion composed the music
on. If you disagree, you're free to replace it with DOSBOX GUS output or
something.
=====
List of major changes (as compared to a straight dumb DOSBOX dump):
Intro: Framed for widescreen.
Interlaced circles: Presented at 60Hz and edited to fit (the dropped frames
from 70->60 were too noticable IMO).
Another Way To Scroll: Motion synthesis to fit 70Hz->60Hz.
Bouncing lenz: Motion synthesis to fit 70Hz->60Hz.
Plasma: Framed for widescreen, presented at 60Hz (preserves the effect) and
edited to fit.
10 seconds to transmission: Motion synthesis to fit 70Hz->60Hz.
Voxel landscape: Presented at 30Hz instead of 60Hz to preserve the effect
(even on Pentium it ran at 35Hz -- only on Pentium III or DOSBOX does it run at
a crazy 70Hz, and the effect is ruined at that speed as the landscape pattern
repeats every 2 seconds).
City flyby: Framed for widescreen.
Future Crew still image: Framed for widescreen and not corrected for aspect
ratio (preserves pixels 1:1).
Credits: Motion synthesis to fit 70Hz->60Hz.
End scrolly: Framed for widescreen, presented at 60Hz to preserve smooth
scrolling and edited to fit (this involved extending the music by one
repetition).
End screen: Framed for widescreen and not corrected for aspect ratio
(preserves pixels 1:1).

Hellfire: Was the plasma section in your capture was post-processed in some way? If not, what DOSBOX version and settings did you use?
I've simply blended two frames of the plasma into one.
There are more authentic ways to preserve the "fake-mode" effect, but this was the least troublesome.

Thanks.
wow, my laptop refuses to play that .ts properly. i think the hard disk is too slow. :D
Data rate isn't killing it, it's using a player without acceleration. Try powerdvd 10 or media player classic homecinema, they should leverage your videocard to some degree. I also read that VLC 2.0 came out today but haven't tried it yet.

Ah, thanks for the explanation. In my file, they're not blended, but play back at 60Hz (file is 60p).

I'm using this player and it's not exactly smooth here, but maybe that's just my PC (Athlon64 X2 5000+) :D
Also, great job working on all these captures :)
trixter, I do use MPC-HC with HW acceleration enabled. I was able to watch full HD videos without acceleration before. But I some 400mb/17 minutes is 20 and a few MB per second, and according to DiskTT I get 30 MB/s throughput for sequential read on that HD, so it could be quite close to its limit...
get some SSD ;)
they got pretty cheap by now!
also they outdo any RAID0-config, haha.

hardy: show me a cheap HDD that can completely replace my laptop's hard disk.
trixter: Watched it today, very enjoyable! (on a SSD and Core i7 + HD 5850, WMP)
Uuuuh.... SSD? 400MB divided by 17 minutes is less than 400K per second. Even if we multiply this by let's say three for the actual effects (the file is constant rate factor encoded and the endscroller is quite long) I doubt any HD is THAT slow. :)
(You really want proper HW acceleration all the way though. Which for Win7 means: Something Media Foundation based, eg. WMP)

Oh yeah, I forgot. Indeed, in WMP it's quite smooth! :)
kb_: You're so right. Second and minutes is not quite the same. Oops. :) That does make it even weirder, though, since I enabled HW acceleration when installing MPC. Something else might be broken, I'll have to check.
