When lowering pixels of resolution of a video, the file size becomes smaller...
Hello!
My question is this:
I am importing a tiff of scope (2048 X 858) 2K sequence in Premiere Pro CC 2015.
When I go to the export section, as you can see in this video link:
First Pro CC 2015 (resolution size) export settings - YouTube
and try to lower the resolution 2048 X 858, 5 X 2 or 854 X 480 or 1280 X 536! the size of the file remains the same! Is this possible?
This means that if I have a 4K video and a video card, they will have exactly the same file size!
I tried to make a sequence of low resolution and drop tiff sequence and adjustment of the sequence in the image of low resolution tiff, but I have the same problem.
I've even nested sequence of high-resolution sequence of lower resolution, but... Nothing...
Does this make sense? What I am doing wrong?
Thank you!

Yiannis, Yes. Unlike a photo, a video, the file size is determined by the data rate. However, the data/flow isn't what determines quality, you need to consider in the codec you use.
For example, a 50 Mbit/s, 720 x 480 H.264 file and a 50 Mbps DV (video only, forgetting the audio codecs) will be exactly the same size. but the H.264 file is going to be better because it's a step more coded with a better compression algorithm.
Another factor that determines the size of the file is the frame rate. I'm not saying that you should drop your rate to save space, but know that if you save 2 files with the same exact settings, but we're 30 p or 25 p and the other is 50 p or 60 p, then the latter will be twice as large.

Hello, I am currently working on a graphic that is displayed on the web. The file size should be 1000 x 1000 pixels and the size of the image can not go more than 250 KB. My picture is to the size of good size, but it is at least 947 kbs.
How can I change the size of the file to 250 KB without losing the strong resolution?
We have the options to save the file as a jpeg, png and gif.
Hello!
Start by opening the image in Photoshop, by clicking on the word 'File' in the menu bar, mousing down to 'save for Web '. The record of the Web dialog box is displayed.
Click on the tab "4 - Up". Now you click on the four components, use the drop-down menu (circled in red below) preset to select different options and compare their relative size of the quality and the file.
In the example above, I've decided to save my image as a JPEG quality closest to the original image while reducing the size of the file in the range I need. So to save this version, I click the pane at the top right corner of save for Web dialog box and click Save.
According to the type of image you are editing, your best results can be PNG or GIF.

stop the images lose the file size when scaled down?
Ive read this tutorial;
http://joedasilva.com/blog/?p=32
and ive just discovered that if put you across a smaller image, the file size is decreased so permanent and expansion of the image again it will be pixalated. If I'm working with images and I want freedom to play with the scaling, do I need to convert them all to grafics?
Is there a setting that I can change so that the images are saved to the display resolution when I export, but maintain there full size of the file in the document? Is this how illustrator works?
Thank youheathrowe says:

lost quality unless you to scale larger than the original.--

I'm trying to reduce the file size of a jpeg file, but the dialog box under image > image size reflects a much smaller that the file is. I saved the image after resampling and simplistic image, the pip size reduced to 72 and lowered the low quality only to see the minimum file size reduction. Why the dialog box in photoshop gives me a different file size than my computer and how do I solve this problem? Thank you!
The Image Size dialog box dialog box shows the uncompressed size.
Your operating system (Explorer/Finder) shows the size compressed. (size on the disk)
If you use save for Web, you can see the compressed size, but also an overview.

Why the file size is reduced when the visibility of the layer is hidden?
With the same PSD file, I have hidden the visibility layer and recorded another copy, and I noticed that the file size is significantly reduced.
Anyone know why?
Thank you
When you maximize the verified compatibility, Photoshop records a version flattened your file in the psd. When you hide the layers and save, of course, the flattened version will consist of your file psd with these missing layers. If these layers had a lot of additional information, as opposed to simply a lot of white space or easily compressible full areas, then you will see a difference in file size.

I record in JPEG, large file size, but the file saves about 3 MB? Then, when my clients want to put my images on a canvas, etc. image false. But when I use to shoot just JPEG saving used to increase the size of the file and the photos were very good to put on a canvas, etc.
Please help and thanks in advance.

I'm not a user of the Canon system, so I'm not familiar with their cameras. But I googled your resolution and found a link.
http://www.learn.USA.Canon.com/resources/articles/2011/eos_qt_small_raw_images_article.htm lp
Apparently, you pull something Canon mRAW calls, which is a 10.5MP raw file designed for 4 K devices. In other words, you set your camera to produce small size raw files, less than half of a JPEG full size. Then you use Camera Raw to artificially enlarge these files in order to compensate by using a workflow setting widens. I hope that I don't need to explain the futility in this!
You need to go back to your camera settings, consult the manual and find out how to produce full raw files standard size. This way you do not throw in detail and then the creation of extensions pixelated.
In short, your camera settings are wrong to produce raw files full size. You are then enlarge the images of 2.4 times and that is why they have air c * p.
You must change the setting of the camera RAW, and therefore you should not expand in Camera Raw.

Why the image size is smaller when going from RAW to Photoshop
My computer has dropped recently and I had to reboot Photoshop CS2 worm 9 and I had to download Camera Raw plugin version 3.7. Now when I
process a Raw file, which is normally an image of 54 x 36 inches, now, I'm getting a picture of 16.2x10.8. I can't find why it is to reduce the size of the file. Any ideas? Help
Thank you

The 'size' of an image is a combination of its dimensions and its resolution. While the dimensions may change, the chances are that your resolution was changed as well. The largest dimension is prolly at 72 DPI (pixel pre inch), and the smallest dimension is prolly more at 300 PPI. Camera Raw has the ability to change that, but also to change the pixel dimensions, check what is the PPI to your second image. If it's more like 300PPI so you just a different ratio. If it is 72 DPI then you did something to downsample the image.

I make a great conference poster that will contain images of ArcGIS. The poster will be 92 "x 42" and Imaging will cover 91 by 22 in the page. The problem is that I need very high resolution for imaging, but illustrator won't import my files. I use ArcGIS 10.3 on Windows 10 and Illustrator C4 with OS X 10.11.1 (El Capitan). I was not able to import any .tiff file into illustrator (is this possible?) and I get "cannot take place due to an error" or "the file is too big" errors when I try to put .jpeg, .png, .ai files exported from the GIS. I think that the problem is due to the differentoperating systems, rental However, can I open and edit (resize etc.) files in preview without any problem, so there is also a problem with Illustrator. The files that I use are more than 150 MB at 300 dpi, but I really prefer to use 600 dpi, Illustrator can't handle these files sizes? I don't want to lose the resolution using .jpeg, .pdf, etc., many types of compression will cause problems with vector layers from ArcGIS. Please notify!
Update your AICS4 to something with the ability to access more than 3 GB of memory RAM as CS6 or above. You'll never work with CS4, at least not to the resolution as you seem to think you need. Indeed, you could probably use 150ppi or the bottom of the poster and not obviously nothing to lose. And for the record, I worked for 17 years for the USGS working with ARCGIS and AI.
