Impossible to say without knowing the resolution, bitrate, and codec of the compressed video. Even individual codecs have different settings that will affect compression. Your question is WAY too generic.

That is a very hard question to answer. There are a multiple number of reasons why.
1. Videos are all compressed and encoded differently, which result in a change in the size of the video.
2. What is the pixel size of the video, as the normal view is bigger, the size of the video is bigger.
3. What is the quality of the video, if your a tech wiz, then what is the bitrate of the video. The better the quality which is the higher the bitrate, then the bigger the size of the video.
4. What about the sound quality. Is it mono, is it stereo, what is the bitrate for the sound quality. That is also a factor in the size of the video.

All in all, I cannot tell you the size of a 5,10,40 minutes video based on the qualifications above. Sorry, you could probably post another one with all the information above.

The size of the video depends on the resolution and the method with which it was recorded.

It depend on the quality of video.

It depends on quality of the video. If its in AVI format,it will have smaller size than in DVD(VOB) format.

Video CD, or VCD, is a digital movie format. It's basically a primitive version of DVD.
A Video CD is a kind of CD. It looks the same as a music CD or a CD-ROM, except that instead of music or software, it holds movies, using compressed MPEG-1 video. Its resolution is 352x240 (NTSC) or 352x288 (PAL), which is roughly comparable to VHS.

Compared to Video CD, DVD provides much higher resolution (720x480 for NTSC or 720x576 for PAL), comparable to laserdisc or even better. DVD movies use MPEG-2 compression, rather than the MPEG-1 compression used by Video CDs. For more information on how MPEG compression works, see the MPEG FAQ by Frank Gadegast. For more information on the actual structure of the Video CDs, see this page from the MPlayer documentation (via Guentcho Skordev). For more information about DVD, see the DVD FAQ by Jim Taylor.

A single VCD disc can only hold about 70 minutes of video, so for a typical movie, you need two discs. You can play VCDs back on a Video CD player connected to a TV, or on a fast PC with a CD-ROM drive. Some DVD players can also play VCDs.

Video CD was introduced by Philips and Sony in 1993. It never caught on in North America, but it became hugely popular in Asia, where most households didn't already have VCRs. In Asia, Video CD players are roughly as common as VCRs in North America: China alone manufactures 2 million VCD players a year.

Prior to the introduction of DVD in 1997, one reason to get VCDs was in order to watch Hong Kong movies. If you're a Hong Kong movie fan in North America (like me), and you don't live in a city with a large Chinese population, it's not so easy to find HK movies locally. But because VCDs are so popular in Asia, almost all HK films released in the last few years are available on VCD: you can easily order them by mail for US $10-20.

Today (March 2000), however, Hong Kong movies are being released on DVD, so I find there isn't so much of a reason to bother with VCD.

The other big advantage of Video CD versus DVD is that it's relatively easy to create your own Video CDs (e.g. from home movies), using a CD-ROM burner. There's a lot of discussion in the Video CD Q&A forum on this topic.

Finally, Video CD is creating a big problem for the movie industry, analogous to the problem that MP3 has created for the music industry: it's very, very easy to create pirate copies of movies using Video CD. When a new movie is released in the theaters, pirates will smuggle in a camcorder and point it at the screen while the movie is playing. Or they make VCD copies from laserdiscs, DVDs, and "screener" copies of movies (sent to video rental stores for previews before they decide to buy movies).

Pirate VCDs sell for $1 or so in places like Hong Kong, Malaysia, or China (since it only costs 5 cents to duplicate a CD). This has been crippling to the Hong Kong movie industry: why pay $5 or $10 to see a movie in the theater when you can get a pirate VCD for $1 and watch it with your friends and family, as many times as you want?

Personally, I dislike piracy and what it's doing to the Hong Kong film industry. I don't buy pirated Video CDs. If you want to know where to get pirated movies, or how to create them yourself, please don't ask me.

Picture quality when using a VCD player is generally comparable to VHS, but I've never seen a VCD that I thought was better quality than VHS, and I've seen several that were quite a bit worse: if the encoding isn't done well (which requires high-end hardware and software), you can see blockiness in the image.
More specifically, VHS resolution is about 300x360, whereas VCD resolution is 352x240 (NTSC) or 352x288 (PAL). Henrik Herranen has an interesting page comparing the resolution of DVD, laserdisc, broadcast video, VHS, and CD-i which shows what this means in practice.

Comments from Rainer Hofmeister (rhofm AT net4you.co.at):


The quality depends on the content of the picture. If there are many details (like in a street scene) or fast movements the data compression affects the quality. You then have an effect like in JPEGs with higher compression. Generally the quality is beneath that of a LD. I have lots of VCDs and I think the quality of the picture is good enough even if you don´t consider the very low price.

For HK movies, two of the major distributors are Mei Ah Laserdisc and Universe Entertainment. According to Charles Amith (amith AT kingsnet.com), Mei Ah VCD quality is typically 8 out of 10, while Universe VCDs are more like 5-6 out of 10.
So what does "5-6 out of 10" mean? Well, I've got a copy of The Bride with White Hair on VCD from Universe. When I play it back on my VCD player, you can see blockiness in the image if you're close to the TV, but it looks fine from a normal viewing distance. A bigger problem is that the subtitles are extremely small, bordering on unreadable (at least on my 20" TV).

The DVD sizes can be a bit confusing. There are basicly 4 different DVD Sizes,

DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.

DVD-10, holds around 9 400 000 000 bytes and that is 8.75 computer GB. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Double Sided Single Layered.

DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media.

DVD-18, holds around 17 080 000 000 bytes and that is 15.9 computer GB. DVD+R supports this format. Also called Double Sided Dual Layered.

* In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB. See section 3.3 in the DVDDemystified FAQ here.


DVD+R/DVD+RW/DVD+R DL and DVD-R/DVD-RW exact sizes
DVD-R/DVD-RW = 4 706 074 624 bytes ( 4488 MB )
DVD+R/DVD+RW = 4 700 372 992 bytes ( 4482 MB )
DVD+R DL = 8 547 993 600 bytes ( 8152 MB )
DVD Write and read speeds

Single Layer(4.7GB) write speeds
1x (CLV) = about 58 minutes
2x (CLV) = about 29 minutes
2.4x (CLV) = about 24 minutes
4x (CLV) = about 14.5 minutes
6x (CLV/ZCLV) = about 10-12 minutes
8x (PCAV/ZCLV) = about 8-10 minutes
12x (PCAV/ZCLV) = about 6.5-7.5 minutes
16x (CAV/ZCLV) = about 6-7 minutes

Dual/Double Layer(8.5GB) write speeds
1x CLV = about 105 minutes
2.4x CLV = about 44 minutes
4x CLV = about 27 minutes

Single Layer (4.7GB) read speeds
1x read speed is 1.321MB/s = ~56 minutes
6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes
8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes
12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes
16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes

* write speed time and read speed time is not the same because writing requires some extra steps and also does the faster writing above 6x usually use lower write speeds for some parts of the dvd. 4x DVD speed = 36x CD speed. See section 4.2 in the DVDDemystified FAQ here.
