The appearance of FF8 movies on the PSX and PC ...

[Perica]

The FMVs in FF8 that are on the PSX version are half the size (the resolution is half the size) of the ones on the PC, but yet they look so much better on a much bigger screen (my television) than my computer... what's up with this ?

Scanlines maybe?

You ever notice that most PSX (or N64, SNES, NES) games run at a resolution of 320x240 or less?  This looks fine on your TV but crappy on your computer screen.  It's because of the way the TV handles images (scanlines/interlacing), and plus, your TV isn't really that clear anyway (try connecting your computer to it and using Internet Explorer or Word or something... kinda useless unless you have the resolution low and turn up the font size).

What do you mean by "scanlines/interlacing"? What are scanlines? What is interlacing?

Is interlacing the insertion of gray lines in an image or video? If so, why are these gray lines inserted? If not, what is it called when gray lines are inserted into an image or video and why are these gray lines inserted?

Scanlines are the lines inbetween the image to space it out to change the resolution ( I think, im not sureo n this)
dunno bout 'lacing

TVs use interlacing to display images.  Here's how it works...

Your TV (if it is NTSC) shows 30 frames per second.  Not really though.  The screen is updated 60 times per second, putting the "even" lines out on one tick and the "odd" ones on the other.  This is called interlacing.  Displaying the whole image at once is called "progressive scan."

Because of this, games and etc. can run at 60 fps if they cut the vertical resolution in half.

Doesn't interlacing cause flicker on PAL TVs?

It can.. PAL and NTSC have fairly complex information on them and for example NTSC has an odd number of scanlines (525) this means 262 1/2 scanlines for each vertical pulse. To actually have a complete frame it takes 4 vertical pulses (called a super frame).

Pal's interlaced frequency is 25fps NTSC 30 your monitor 60 to 90
Flicker can be caused by a number of things (bad game programing can cause it for example).

I don't quite understand. What causes the black lines? Are all the odd lines updated and all of the even lines are left black and then on the next refresh all of the even lines are updated and all of the odd lines are left black? What is the purpose of interlacing? Is there an advantage at having a faster frame rate even though it's just showing different parts of the same image (odd and even lines). Is the way I understood interlacing to work correct at all

Interlacing is/was used to increase the viewable image size on a limited bandwidht signal. Look at what is happening inside a normal television.  A signal is sent then recieved by the TV. The TV converts the signal in real time into RGB data and puts it to the screen. Thus the signal is actively driving your display. This is important to remember that in order to maintain an image on a CRT you have to continously refresh the data.  NTSC uses 2 fields to form a basic sub frames this gives the perception of having more data available even though there isn't.  The CRT's phospher's decay after being excited by an electron beam. It takes roughly 1/60th of a second. It maintains an image by using your brain persistance of vision.  So the image is semi static on an older TV.

Digital Television uses progressive scaning. This means that the device generates and displays the image and the data channel sends just what information changed. Thus the channel (IE TV signal) is no longer used to directly update the displayed image constantly, only the processor in the device does that.  It also means that the resolution of the data is much higher.  In a static image on a TV no new data might be being sent.  Or data is being queued for the next scene change.  It's all controled by a meta stream that contains the actual data being viewed (MPEG2 is basically a meta stream of audio video and other data)..

I hope this makes sense
