A1000 S-Video Hack video now on Google Video
« on: March 25, 2007, 02:50:56 AM »
I finished the video of my S-video hack and placed it on google video.  The video turned out okay, but I'm very disappointed by one thing.  When I try to show comparisons between the Composite and S-Video, I zoomed into a section of the screen (since google video is only 320x240) so that hopefully people could see the huge difference.  However, after being compressed with their MPEG4 compression, the difference seems very subtle, but on my local machine (before compression) it is considerably more noticable!  Anyway, here is the link:

The one thing that's wrong about your video is you say you got a neobitz board... it is not... it is it's smaller cousin, the neobitz-S.

The real neobitz converts RGB to component, not to S-Video.

I got a price on the Neobitz board that does component output.  It's $85 + $5 shipping here in the states.

I'd really like to see how good an Amiga outputing component video would look.


Adric..  Have you tried workbench in interlace mode?  I'm very curious if your LCD TV will upconvert the interlaced workbench screen and act as a flicker fixer/scandoubler.

Thanks for the video, bro. Looks like a sweet little device, think I may try the component version. I'll put the neobitz in in own small enclosure, and just "rig" a few exterior connectors on the rear of my A500 and A1200. Looks like a better option than trying to hunt down a scandoubler.

Applause!

Well done video, good shots, and music that matched. Very informative.
Amiga 3000D UP and running! Hear that clicking. 8)
Amiga 3000D & 4000D in storage sadly.

Nice video Adric!

Now if neobitz only made something that could take RGB @ 15Khz and upscaled it to 31Khz :)

I have two different boards:

Neobitz - Supports component video, svideo, and composite video.

Neobitz-S - Supports svideo and composite only.

I watched the video -- you did a very good job.

Didn't you like the gold-plated SVideo jack that was supplied with the Neobitz-S kit?

except for I doubt if this will work with all screenmodes - works fine with scandoubler.  If someone can confirm that it does not work with all modes, then its not worth spending $85.

Didn't look bad at all.  A pretty professional quality video, IMHO.

I'm interested in such an SVHS-on-a-chip solution for other systems which have been SVHS modified using standard components, and not so well I might add -- Atari 7800, Atari 5200, Atari 800XL, Nintendo Entertainment System, to name a few.  Thankfully the 64 and 128's have an SVHS-compatible output which just requires minor cabling.  These systems don't have RGB on the boards, though... bummer.

I'd hazard to say that a low-end LCD TV is not going to support an interlaced screen without flicker.  I'd hazard that a high-end one will not either, considering that like a regular monitor or TV, the LCD TV is expecting a certain signal, and an interlaced screen falls outside of its expectations.

True dat... but good for the person who is simply using it for old games, basic 15 KHz modes should work fine.

I sold my DCE internal scandoubler years ago, and almost bought another until I remembered all the downsides:

Still have nasty 50 Hz flicker in PAL screenmodes, unless you use an LCD... in which case you have to put up with irregular scaling (or a smaller, non-stretched image, if the monitor will allow you to select it). Both of those options are far less than ideal (for me, anyhow).

External scandoublers exhibit marginal image quality.

Still pretty much confined to a computer monitor, and not all monitors will look good with a particular scandoubler output


Possible neobitz advantages:

Great for most games/demos

Plug it into ANYTHING that accepts s-video or component

Potentially fantastic image quality

$85 is still cheaper than any scandoubler


I suppose it just depends on what you need. Unfortunately, a good "do it all" display option for old Amigas is nonexistant.

Whoah!  Very educational, great video editing, totally awesome.

Can this be installed (just as easy) on an A600 as well?
Code 6502 asm or... DIE!!

[C64, C128, A500, A600, A1200, A3000, MBP+Mini, Efika/MOS2.1, Sam440 w/AOS4.1

I have never seen inside of an A600 before.  I am sure it would work electrically, I just don't know if there is room inside.

Technically the neobitz board shouldn't need to.  All newer HDTV's will upscale the incoming signal to it's native resolution.  Remember..  TVs are different than LCD computer monitors which will display the resolution that you feed them.

Example : I have a 42" panasonic plasma that does 720p.  All incoming signals are converted to 1024x768. If I feed it a crappy 640x480 interlaced signal it's upconverted.  If I feed it a fully digital 1920x1080 resolution signal it's downcoverted.

If you have an EDTV (420p) or an HDTV (720p/1080i/1080p), the incoming signal signal will be displayed at 31Khz.  Progressive screen modes are at least 31Khz.  

HDTV's have scandoublers, deinterlacers, and scalers built in.
