What is the Standard of VHS Resolutiion

[Greg12]

What is VHS resolution

I mean like VCD is 320/240.
SVCD is 480/480

I am encoding some still pics as AVI's. Shall I go with VHS or DVD resolution?

[Dward]

According to http://www.vcdhelp.com/comparison.htm, it's 240 lines.

[nidoran]

actually VHS doesnt have a resolution as far as i know

it uses a film which is unrestricted to resolution. most ppl are saying its a 320x240 resolution cuz its comparable quality. some are better, some are worse, but whatever.

[Xitanium]

strictly speaking it is 480 interlaced lines, wich is like 360 progressive lines (these are visual anoligies) so its usually better than vcd and worse than svcd.

[Greg12]

Then what is 640x480?

[nidoran]

640x480 is TV standard; or at least NTSC tv.
640x576 is europe TV

[Greg12]

I wonder what a VCD at that resolution would look like.


IT would be like SVCD quality but using MPEG1

[statuspending]

that would make it xVCD...no?

therefore, the amount of time you can fit on one cd is variable...

In a way, you're talking apples and oranges, Greg, as televised video is usually measured in lines of resolution while computer video is measured by pixel count. However - 640 x 480 is the size of a "full-screen" computer monitor video, which is usually scanned down to NTSC- or PAL-quality video. In the case of VHS-quality NTSC, you're looking at 126,000 pixels (240 lines horizontal resolution x 525 lines of vertical resolution) at 59.97 fields (half-frames) per second, while full-screen computer video has a resolution of 307,200 pixels (640 lines across x 480 lines up and down) at 60 full frames a second. (For some reason that escapes me, horizontal resolution on televisions, VCRs, etc. is measured *vertically* on a resolution chart.) That means that a 640 x 480 screen gives you 585 lines of horizontal resolution, which is better than most current broadcast television is....

Confused yet? Think of how *I* feel - I have to live with this! <g>

So when I put a movie into my VCR and hit play, what am I seeing?


I want to do an xvcd that will have the height and with of a VHS movie.

try 640 x 480

[kinneera]

Or 704x480, in computer pixels this tends to scale to TV well (double VCD res of 352x240).
