That's a tough one. The only accurate method of determining compression ratio is hind-sight ;) First of all, there's many types of compression. Even within a specific type, it's difficult to predict the precise amount of compression. Generally, compression tokenizes repeating byte sequences - the more repetition, the higher the compression ratio. For example, if you were to make movie that had nothing but a white screen, you could probably make several hours of this movie, then compress it down to fit on a floppy disc. On the other hand, if you were to film an overly impressive fireworks display, you might soon run out of memory. There's 2 general categories for compression: loss (usually low-loss) and loss-less. While the loss type reduces presentation quality, loss-less does not. Compression techniques such as MP3 uses a blend of both. This allows you temper size with quality to attain an acceptable result. So, pick one, and after a while, you'll get a feel for how much compression to expect.

Who is the girl in the title sequence for the original Pokemon that Pikachu dives under then jumps back up with the sun in the background?
Pokemon GirlShe is a generic character based on the Lass enemy trainer class from the Pokémon video games. Actually, in the Asian title sequence they talk about where Pokemon come from and they say in forests, water, some other places and then they say "and even in that girls skirt. If you watch the Asian version with subtitles you will see.
What is the difference between 35mm movie and 70mm movie?
There are a lot of film formats created for showing video. 35mm or 70mm denotes the projection gauge or width of the release print film. A number of film formats produce release prints of the width 35mm and 70mm. The major difference in film formats is the aspect ratio of the rendered picture. The aspect ratio of the video shown in television is usually 4:3 while that shown in a movie theatre is 16:9. The quality of the picture seems to be good in the latter aspect ratio. Plz Check http://en.wikipedia.org/wiki/List_of_film_formats for more info
What is the relationship between a pixel and a resolution?
I assume you are referring to data compression, specifically video or audio. Resolution is how precisely a binary representation details an original piece of information. if it's audio, it usually refers to how many bits are used in each sample, and it tells how accurately each sample matches the original sound wave. if it's video, it usually refers to how many pixels each frame is made out of (same for still images). Usually people refer to only the height and width, but color depth also is included in this definition too. Bitrate determins how much actual binary data a given resolution of information will take up. Normally, these would be directly proportional, and you could exactly calculate them. For sound, take the sample resolution * sample rate * number of channels = bits per second. For video, take width * height * bit depth * frame rate = bits per second. However, with compression, bitrate often will determine how accurately that binary data is stored in a compressed data stream. Generally, the higher bitrate you use, the better it will look, and the higher resolution you use, the higher bitrate you need to maintain constant quality (compared to lower resolutions).
When you watch FOX News Channel why are their black bars on the top and bottom of the screen?
Oh, it looks like those black bars are there to make sure the picture fits properly on your screen. It's just a way to maintain the right aspect ratio and make sure everything looks nice and balanced. Just like when we add a happy little tree to our painting to create harmony, those black bars are there to keep everything in balance on your screen.
How long is 2355mb in hours or minutes?
A mb is a measure of electronic storage and not a measure of time. The amount of information that can be stored depends on the nature of the information, its quality and the compression. You will get a much shorter time of high definition video with a low compression ratio compared with low definition audio with a high compression factor.

What is the difference between MPEG JPEG and?
1. JPEG stands for joint photographic expert group and MPEG stands for motion picture expert group. 2. JPEG is used for picture compression and MPEG is used for video compression. 3. JPEG typically achieves 10:1 compression with little perceptible loss in image quality, whereas compression ratio in MPEG is 30:1 for general video using H.263 and 50:1 for general video using H.264/MPEG4. 4. JPEG and MPEG both uses lossy compression.
What is a popular video compression standard?
MPEG
Is a MP3 a type of video compression?
no.audio
Which video compression format is used by websites?
The video coding format MPEG is used through the web for video compression. MPEG goes up to MPEG- Part4 that is shortened to MP4.
What video compression do you use?
The compression used will depend on what you want to do with the video. MPEG-2 is used for burning to DVD's. MPEG-4/H264 can be used for streaming from a website. The length of the video and available bandwidth are also considerations when selecting a suitable compression format.
How can I resize a video in Premiere Pro for Instagram?
To resize a video in Premiere Pro for Instagram, you can adjust the sequence settings to match Instagram's aspect ratio of 4:5 or 9:16. Then, scale and position your video within the frame to fit the new dimensions. Finally, export the video with the appropriate settings for Instagram.
Why does Premiere Pro zoom in my video?
Premiere Pro may zoom in on your video if the resolution of the video is higher than the resolution of the sequence you are working in. This can cause the software to automatically zoom in to fit the video within the sequence frame. To avoid this, make sure the sequence settings match the resolution of your video.
What are disadvantage of video compression?
Following are the advantages of Video Compression:- Occupies less disk space.- Reading and writing is faster.- File transferring is faster.- The order of bytes is independent.Following are the disadvantages of video compression”- Compilation need to be done again for compression.- Errors may occur while transmitting data.- The byte / pixel relationship is unknown- Has to decompress the previous data.
How can you reduce memory of video file?
Using compression.
What Was formed by ISO to set standards for audio and video compression such as the MP3 audio compression standard?
MPEG
