Exported file size/Lecture Capture

I have been doing some lecture capture using iShowU which captures my laptop screen and simultaneously capturing the audio on an iPod with an XtremeMac mic. I prefer to do it this way rather than capturing the audio with a wireless mic in the iShowU application, given some unpleasant experiences with computer crashes with large Powerpoint files. I have then melded the two using iMovie and want to export as a QT. However the export time is incredibly long. For a 6 MB video file and 45 MB audio file, it takes 2 hours and I end up with a 92 MB file! Any suggestions welcome, as I am new to audio/video software.

I have used the drop-down menu that appears when "exporting" and selected the jpg-original size option
When you export a version with "jpg-original size", Aperture will render a new file, with the pixelsize (width and height) of your original image file, but tat does not necessarily mean that the file size will be equal to the file size of the original image file. The filesize will depend on the jpeg quality setting. The lower the quality value, the smaller the file size.
I'd suggest you check your "jpg-original size" setting. When you are sharing or exporting, select
"jpg-original size" and then set the Export preset to "Edit". Check, if the "size to" is really set to "Original size" and check the jpeg-quality.

LARGER Exported File sizes

I recently upgraded to LR V2 (also use PS CS3)
For some reason my exported file sizes have increased immensely
Typically I would convert from RAW to TIFF with the following settings:
11" x 17" print size
compression: none
Adobe RGB1998
16 bit
resolution 300 DPI
These files would convert at about 90MB (manageable on my system)
They are now converting at a whopping 400MB (aging system can't handle this!)
Is this the new LR V2 standard, is there some setting I need to change?
Any help greatly appreciated.
Rich

No, you must be doing something wrong there. 300 ppi (NOT DPI!) at 11x17 and 16 bits uncompressed should be 90MB as you can calculate with simple math. If you enable compression (highly recommended for tiffs - it's lossless compression) you should be able to cut that in half.

SSRS report Excel Export file size is huge

Hello everyone,
I am facing an issue with SSRS report exporting to Excel.
Issue : Exported file size is too big.
I have a matrix report ( parametrized report ) it fetches data from multiple table.
initially when
1) I select all parameters all values
2) load the report after that
3) exporting to excel
so exported file size was about 10 Mb to 12MB
Now, suddenly from this month exported file size is too big around 62 MB for same data,
I checked on different forums and tried the solutions but it didn't worked,
can anyone please suggest me on this.
My environment is
Visual studio (BIDS) 2008
SQL Server 2008 R2
Excel 2007
Thanks

Hi UdayKGR,
According to your description, when you export a report into an excel file, the exported file size is too huge. Now you want to reduce the file size. Right?
In this scenario, do you export the report into excel 2003 file? When reports are first exported and saved to Excel 2003, they do not benefit from the file optimization that Excel automatically applies to its *.xls workbook files. The larger file size can
cause problems for e-mail subscriptions and attachments. To reduce the size of the *.xls files for exported reports, open the *.xls files and then resave the workbooks. Resaving the workbooks typically reduces their file sizes by 40 to 50 percent. Also please
try to install the Reporting Services 2008 R2 Service Pack 2 and reduce the merged columns in exported excel file. For more information, please see the links below:

If you have any question, please feel free to ask.

Why is the exported file size so small?

Hello!
I just spent the last few days watching about three hours of Adobe Premiere Pro CS3 tutorials and almost all five hours of the Adobe Encore CS3 tutorials on Lynda.com with the awesome 30-day trial that I received for purchasing these two programs. I pretty much got to the end of authoring my first DVD with Encore, but the file size is so small that it doesn't even take up the full size of a single-layer DVD and I was expecting to be using double-layer DVDs.
Here's why I didn't post this in the Encore discussion: My two file sizes are 10GB and 8GB. I have them both as single timelines in Premiere Pro and exported them each to Encore. But why does the file size decrease to just over 1GB for each of the files in the Export to Encore option in Premiere Pro CS3?
I begin a brand new project in Premiere Pro, import the 10GB .avi, and then do the Export to Encore with "DVD Double Layer", "Author with Menus", "Entire Sequence", "NTSC High Quality" with the quality level switched from 4 to 5, Video Codec = "MainConcept MPEG Video", 720x480, 29.97 drop frame, Lower, Standard 4:3, VBR, 2 Pass, the default bitrate settings of Minimum Bit Rate = 1.5, Target Bit Rate = 4, Maximum Bit Rate = 7, and then whatever GOP Settings are set to M Frames = 3 and N Frames = 15. Without any video editing at all, it estimates the file size at 1.7GB.
If my goal is to get the file sizes closer to 4GB and 3.5GB, can I fiddle with any of these settings without screwing up the ability for all DVD players to read my disc? I thought it would probably be ideal to have them closer to 7GB and 6GB, and then let Encore downgrade the quality to fit all of the content on the DVD with very little room to spare. But why is there no default to keep the video resolution at the absolute best possible?
Should I be exporting to a Movie instead of exporting to Encore?
Thanks!
Matt

Bloated PDF Export File Size

I just exported a 2 page file that contained 3 graphics and
text. The file was an 493K in size and could not be made any
smaller using Adobe Pro 7.0. This is amazingly large since the old
Buzzword graphic PDF output was 393K. I then exported the file as a
Word document and then printed a PDF output using Adobe Pro 7.0 and
the file was only 95K.
This new PDF export feature is a disappointment. It produces
way larger file sizes than any PDF produced by an Adobe desktop
application. Why is it so inefficient?

RLarimore,
Sorry to hear about your disappointment about this feature.
This problem is known and I think Adobe/Buzzword team would be
improving it in future releases (though I don't know their
time-line or feature priority). This was the first cut
implementation of this feature - and nobody knew what folks would
want to see improved first. I guess now we know :).
What would most likely be the problem: Fonts embedded inside
the PDF are subset-embedded but not fully optimized and that would
have led to big size. Fonts are difficult beasts to tame, and I am
sure they would be tamed someday.

Preview: how to find export file size?

Odd that I didn't find a thread on "save-as". Are they squashed?
I lament the loss of "Save as…", but I would be willing to accept the use of "Export…" wholeheartedly if I could predict the file size.
One of the main ways I use Preview is to normalize images without a lot of heady image editing; colour tweaking, size, ratio, resolution, then save JPEG's for use in iTunes cover art. The end of this task was normalizing an image file size as a JPEG. Now, all I see is a slider that gives me a relative file size and no indication of the absolute range I'm working within. The only way I view my desired file size is to export, then use Finder "get info" to see the file size as disk usage.
Is there a way to do this inside the Preview application, as a parameter of exporting, like I did before Lion?

Thought I'd complete this thread that I found unresolved.
In subsequent versions, the absolute value is at the bottom of the export dialogue box. If it was there or toggled at the time I asked then I couldn't find it, but it is now so problem solved. Currently running v8.

Export file size help...output seems way too big

I have a 12 minute movie with audio, video and stills in it.
Currently when I export it the file is 865MB... I need it to be less than 100 with decent quality. It is a tutorial video that will be downloaded from the web.
Can you please give me some direction on how to do this? On what variables to change etc. I know if I exported this out of Camtasia Studio, it would be around that 100 or less bench mark .... problem is I don't know what the settings for the Camtasia preset are.
I am using the following setup:
Quicktime Format
Summary:
Output:
1400x790, 15(fps), quality 100
48000 Hz, Stero, 16 bit
H.264
Source:
Sequece, 01-OverviewSWKit
1920x1080 (1.0), 24fps, Progressive, 00:12:03:12
48000 Hz, Stereo
Settings:
Video Codec: H264
Basica Settings:
Quality 100
Width/height (1400 x 790
Aspect: Square pixels (1.0)
Render at maximum depth - "UN"-checked
Depth: 24 bit
Advanced Settings
Key Frame every 1 frame - "UN" checked
Optimize stills - "UN" checked
Frame Reordering "UN" checked
Bitrate setting:
Limit data rate to xxxx "UN" checked
Use Maximum Render Quality - "UN" Checked
Use Previews "UN" Checked
Use Frame Blending "CHECKED"

Well, with the Apple H.264 encoder in a QuickTime container, you're a bit limited to the number of things you can tweak to decrease final file size. Using a more advanced H.264 encoder, like the free x264, will give access to many of the more "high-tech" bells and whistles that are part of the H.264 standard. One potential would be to tick the "Key frame every # frame" box and try a few values there, usually at multiples of your frame rate. Key frames are "whole" frames that take up much more space in the final file size, and decrease their frequency might help slightly decrease file size, though it will also affect quality.
Short of changing the dimensions of your destination video, decreasing the frame rate, or changing the bitrate of the video and audio streams, you will eventually reach a limit of how much you can push one parameter or another. You might try using H.264 in the Format (not codec) dropdown; this will give you a bit more control over encoding to an H.264 MP4 file. Unless you specifically need a QuickTime MOV, you might find you get better results with the H.264 MP4.
These are of course just the options in Premiere itself. Once you go outside the castle walls, you can find a whole bunch of other options, though they usually come at a steeper learning curve. The big thing to remember is that there is no free lunch when it comes to encoding; you have to give a bit here to gain there, and it's all about setting thresholds of what you're willing to accept.

Export File Size meter

I wish the export dialog calulated the file size based on the quality, type etc.
EG: If im exporting a jpeg and slide the quality slider it would be cool to know what size of file i would get before exporting.
Thanks,
Braden

I would like the ability to set Export by File Size, or the ability to Resize an Image upon Export by pixels as well. Often times I'm exporting images from Lightroom just for email or the web and want them at about 100 pixels in JPG. Even setting the Quality on Export to 1 usually leaves a .jpg shot at about 300 pixels, and too big to view without using a software slide viewer without scrolling. So I have to Edit the images in other photo software to do this, which is an annoying additional step.

Export file size for youtube

Hi
After reading some of the comments regardind new users I am a little hesitant to pose my question . This is my first post.
Nothing ventured, nothing gained, so here goes.
I have a Panasonic X900 video camera which produces excellent shots at full HD1080i .(PAL AVCHD))
The file coming from the camera is a .M2TS which I gather is a mpeg variation. A typical shot of 3 minutes is over 300meg.
I usually create a sequence from the clip and then edit the clip.
So far so good when I am exporting for use on a DVD.
I have been asked to video someone doing a dance sequence and to place this on YouTube.
(Original file size 300meg)Trying numerous settings, the smallest I can get my output file is using H.264 with a YouTube SD 360 wide screen Preset and this gives me 28meg.
I see numerous .MP4 videos on YouTube of 10 minutes or so and they are still only around 50meg and have reasonable full screen quality.
I have tried importing one of those and creating a sequence from it but they are normally NTSC and 29fps .
On the above basis, if I filmed a 9 minute clip and exported it as H.264 etc it would still be approx 70meg.
I have tried reducing the target bitrate and it certainlyreduces file size but poor quality.
If this is the best that can be achieved, then so be it.
Any suggestions on how to get a reasonable quality result while keeping the file size reasonable would be appreciated.
Regards
Brian

Export file size is different from the original raw size

Could someone explain to why, when the original size of a raw file in a folder is about 11mb. But when in Lightroom is shows about 7.1mb. When I export it to a jpeg the size becomes around 3.5mb.
I know that sRAW1 file is 7.1mb as stated in the book. But why does it go down to about 3.5mb when exported to jpeg.
Is there a way to export it to the a higher size? Like 7.1
I used sRAW1 in a canon 50D.
Thanks,
Ray

The "actual" size of you images file is measured by this basic formula, 8-bits is one byte. Each pixel has one byte for the Red, one byte for the Green, and one byte for the Blue colour channels. So, we have 3 bytes per pixel. Multiply the total number of Mega Pixals of your camera's sensor by 3 and you have the true size of an 8 bit image file.
How this image will end up in a final file size depends upon the amount of compression you choose to apply.
The more complex the image, the harder it is to compress without some degradation of image quality. So the original size of an image will not always be a guide to its size when compress. For instance an image with little or no sharpening applied will compress to a much smaller size than the same image with a large amount of sharpening even though the same compression settings were used on export.
If you wish to resize your images on export from LR in specific megapixals (and therefore MB's) then LR/Mogrify has this functionality.
There is a nice simple explanation of this here

Lightroom export file size: why so small? How can I maximize image quality?

My image file sizes are much smaller after editing and exporting through Lightroom. Is it impossible to maintain original file size to preserve image quality? Will this smaller file size have negative impact on prints? Any help is appreciated!

My view on this is somewhat different ...
Jpgs should never be edited, except as a last resort. And it defeats the purpose of working with raw files if you export a jpg, and then edit it.
Agreed. Unfortunately there are many cameras that only output JPEG format files. The camera file (or any other original JPEG file) is your "raw" unedited file inside LR. If you need to send the file to someone else for further editing who doesn't have LR then Exporting with 100% Quality setting might make sense. I say "might" because it's still possible to get very good results using lower Quality setting JPEGs if you only re-save the file one (1) time after further editing. I agree that 16 bit, ProPhoto RGB, TIFF Export files are best for "critical" work and when using 'Edit in Photoshop' from LR.
I suggest taking a look at the JPEG compression image tests on Jeffrey Friedl's Blog. It's a wealth of information! LR's Quality settings range from 0% to 100% or 100 Quality levels. In reality there are only 13 Quality levels, which are the same as in PS.

I use LR JPEG Quality settings of 77-84% for outside printing and LR 62-69% for web posting. I've yet to see any compression artifacts using these settings and I am a pixel-peeper!

If someone gives me a jpg to edit, I always save it as a tiff and convert to 16-bit, to minimize furhter deterioration. I realize that this will not be true 16-bit - no information is added to the image - but my impression is that it will withstand heavy editing better, and not end up with a comb-like histogram.
Why not simply Import the JPEG file into LR and do all your editing non-destructively? There's no need to convert the JPEG file to TIFF unless you need to use LR 'Edit in PS.' Lightroom uses a16 bit/color, ProPhoto RGB, Linear Gamma workspace for all images even when editing sRGB JPEG files.

Export file size problem

I have a .png image which is currently, and needs to remain on a transparent background.
The canvas size is 1947 x 926 pixels and its resolution is 300 pixels/inch.
The math will tell you that the physical size of this image is roughly 6.5 inches x 3.1 inches (which is the final size I need the image to be once it gets inserted into a Microsoft Word document).
The file size is 1.80 MB.
Is there a way to reduce the file size, without sacrificing image quality once the final Word document gets printed?
What format should I export the image as, keeping in mind that the background must remain transparent?
The .png image currently has around 50 layers. Do I gain anything by flattening the layers or something similar?
Thank you for any advice you can offer.
Brian

Go to File > Image Preview, and choose the PNG32 format. This is a good all-around format that supports transparency and non-lossy compression. In the upper-left corner of the preview window, you'll see the output size; it should be a lot less than your current file size. From here, you can click "OK" to save the settings or you can Export.
For an even smaller file size, you could try PNG8 with Alpha Transparency, but this format allows only 256 colors (like the GIF format), which makes it a good choice only for flat graphics (i.e., text and vector-based artwork), not for bitmaps or gradients.
As far your original Fireworks PNG file, you could likely reduce its size by flattening layers—particularly bitmaps. But then you'll sacrifice editability. And it won't impact the output size when exporting the file. So I'd probably leave it as is.

Export file size differences

I'm am trying to export my iPhoto library to a new machine, I don't want to simply copy the iPhoto library folder as a lot of junk has built up over the years and I want to do a fresh import.
What I am doing is dragging my events out of iPhoto and into folders in Finder, however I've noticed that sometimes the file size of what is copied out of iPhoto differs from the size is gives within iPhoto
Any ideas why this would be? It shouldn't be doing any kind of compression on dragging out of iPhoto shout it? I assumed it would just copy the photo (original or modified) but this doesn't seem to be the case.
Any ideas?
Cheers

This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue.
Remember that if you go this route then you break the non-destructive editing feature or lose all the work you have previously done in iPhoto.
To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.

Exported file size is too big?

Ok, this is what has been happening:
I input a 600kb .jpeg image into photoshop touch.
I do nothing to it except to change its transparency from 100% to 75%.
I then export the resulting image to the gallery, as either a .png or as a .jpg.
For some reason, the resulting .png is suddenly 3.6mb, and if export as a .jpg instead it is 1.6mb.
I am not sure if this is a normal effect for photoshop programs, however as the image resolution is the same, I dont see why the file size is increasing by so much. At the very least, there should be an option for controlling the compression of outputted files?

The photo was taken with a GoPro 3. Exported to Camera Roll as JPG.
What I did notice was that when I used Filterstorm Neue, at 100% JPG quality, it also spat out a 25.5MB file. Changing this to 98% yielded 7.5MB. My guess is that Photogene4 automatically selects a JPG quality that matches the original size? I certainly can't tell the difference in 2% quality that's for sure... It's nice to have the option in Filterstorm Neue.
Working on these 3840x2880 files in Photoshop Touch is awful - the images appear grainy and it's slow to use. Pixelmator and others have no problems using layers and working on these size images.
