How can I reduce movie file size?

In the previous version of iMovie it was possible to significantly reduce file size in order to post it on a webpage. I'm not seeing those options in the new version of iMovie. Am I missing something? It's simply impractical to try to post very large files for perhaps a one minute video. Tom

First up 1024 x 768 is a little bizarre, that's neither PAL nor NTSC!
Widescreen video on a computer display is 1040 x 576 (for square pixels).
If you want to make it auto run on a DVD it will be scaled to fit because DVD's don't play video back at anything other than PAL or NTSC resolution. For a computer display (which would be much better for this strange resolution) then use QTPro or FCP to export it using the H264 Codec or Sorenson 3 and this will compress it. Compressing without reducing quality is not going to happen, it just depends on how much you compress it and how much you don't notice the difference, compression by definition is lossy. I would keep the video bit rate up above 1000 kbps.

How can I reduce the file size of 3 videos?...

...without losing quality? These three videos are as follows in terms of size and length of the video:
1) 148MB 19minutes
2) 357MB 18minutes
3) 164MB 14minutes
I tried using a video converter to reduce the bit rate in order to reduce the size, which i know affects the quality, but that did not actually work to reduce the file size this time.
I thought perhaps i should ask my forum friends for help on this matter. How,if at all, can I get all three of these MOV's under 100mb or to a total of 300mb for all 3 and preserve quality? It has to be able to play on an ipad (MOV or MP4). Thanks for your help!

I think that the point that David was trying to make is that reducing the amount of information originally provided by a product or part of it in order to make it smaller will inevitably reduce the efficiency of the product itself.
However, you don't have access to the original masters? Then you might be after a good compromise, meaning a video that can display decent quality while playing at its original frame size (say on the web).
Does this mean that there is no real way to reduce the size without losing quality?
If your target is the web there is a way to reduce the file size and still make it look decent enough. Re-compression means loss of source information but video compression is an art on its own and can produce some amazing results!
Not without testing though.
Now back to my previous post, use Compressor to try to reduce the file size and compare the result quality. Trust your eyes and be honest with yourself.

How can I reduce the file size when saving a psd as a pdf

I have a psd with graphics and text, it is 8.5 x 11, 300 ppi
I flatten the image and go to save as .pdf I un-check all of the options in general.
In compression, I have tried a dozen different combinations and the way I've found to get a document that is not pixelated or blurry is to use jpeg 2000 > lossless or jpeg > maximum.
So I have a high quality document but the file sizes are around 900 kb.
I have downloaded other people's documents of the exact same type and size (8.5 x 11, 300 ppi) that I am making and viewed them in Photoshop, they are not pixelated or blurry and their file sizes are 300 kb or even less than 200 kb
How are they doing this?!

Delete all unused, invisible layers.
Sometimes zip compression is better than jpg compression (in the pdf output settings). Zip is lossless, and works better with non gradient colour or no images.
Flattening the image before you save it to pdf can reduce the file size if you are using jpg compression.
Post a preview of your pdf and we can comment further on how to reduce the file size.

How can I reduce the file size of a pdf when exporting?

I don't want to just choose between high quality print or smallest file size.
I want to export it from 60MB to 40MB.
Can I do this manually? When I use smallest file size the quality is too low and the content looks bad.
But high quality print exports my PDF at 60MB which is too big.

You cannot simply legislate the size of a PDF file. If you content is primarily text and vector, there is not much at all you can do to reduce PDF file size other than to cut out content. Otherwise, the only other variables are those of downsampling and compressing the raster images from your content.
You must be very careful in choosing the PDF export settings. The “smallest size” settings yield PDF files that realistically really are not fit for printing and may mess up any CMYK colors. The “high quality print” and “PDF/X-4” settings yield best print output, but yield the largest PDF files since they do less image resolution downsampling and only the maximum quality lossy JPEG compression.
I would recommend that you start with either the “high quality print” or the “PDF/X-4” settings and make a custom set of export settings. Assuming that you aren't going for offset or gravure printing, change the color image and grayscale image downsampling values from 300 and 450 to either 200 and 275 or no less than 150 and 225. If that doesn't give enough file size reduction, change the compression image quality from “Maximum” to either “High” or no less than “Medium.” Beyond these changes, you may end up with PDF files that will neither print nor display with any reasonable quality.

How can I reduce the file size when PDF Optimizer does not do much?

I have a PDF form that exists of 48 pages. 44 pages are forms / have form fields, the other 4 are just informative. Each form-page has approx. 80 fields (checkboxes, text fields).
When I started setting up the PDF form the file size was 12 MB and I had placed fields on 21 pages. Then with 34 pages the file size was 19 MB. And with 40 pages it was 35 MB big! Finally with 44 pages the file size is 34 MB.
So I searched with Google and found some tips. Using the "PDF Optimizer" option inside Acrobat for example. So I did, and the file was reduced only with 3 MB... 31 MB was the file. Also used the option "Save as.... Optimized".... no difference. I also found a suggestion about removing embedded fonts. Using the "Audit Space Usage" option I noticed the fonts taking many MegaBytes:
* Content Streams: 5.287.000     15,09 %
* Fonts:                24.556.810     70,08 % !!
* Acrobat forms:      3.349.164    12,05 %
In the older PDF version (I saved and kept this one too) with just 21 pages with form-fields, the "Audit Space Usage" shows:
* Content Streams: 5.292.000     40,14 %
* Fonts:                 1.290.224     9,79 %
* Acrobat forms:      1.588.758    12,05 %
So I could save many many MegaBytes by -UnEmbedding- fonts. But if I do this (unembed ALL fonts), the file size stays almost the same!?!?!? Why? What can I do to reduce the file size? I would like it to be 8 MB if possible (32 MB - 24 MB = 8 MB)?
Thank you for your help!

If you have authored the form, reduce the number of different fonts for the content and form fields.
Any font used in a form field will cause that font to be embedded into the PDF.
If you are going to Optimize the PDF be very careful with forms. Optimization does a lot of removal of items and rearranging of items which can really mess up forms.

How can I reduce the file size rendered by After Effects?

Is AE's encoder really that inefficient?
The thing is, AVI doesn't mean much.
It's pretty much an empty container box, which doesn't imply a quality level.
So, AME could default to something completely different as a starting point to produce an AVI file.
AE defaults to uncompressed video when you pick AVI as a format. So, obviously this produces huge file sizes. There could be similar quality thresholds with smaller sizes if you pick other AVIcodecs, but that's a different subject. And in any case, when you're rendering a production quality master, file size is usually not your main concern. You typically use this high quality video file as a source for compressed flavors for distribution. So, pristine video files with huge sizes are a good thing - people then wonder why trailers at apple.com, for instance look so good. And the thing is, the most compressed formats benefit enormously from having an uncompressed file as a source.
Regarding encoding efficiency, yes, AE is less efficient than dedicated encoding solutions. Above all, because it doesn't support 2 pass encoding. Note that for some formats, 2 pass makes a night and day difference, while for others, nothing as drastic as most users seem to believe.
All of this is a moot point for AVI, because the default AVI codecs don't offer these encoding options, which are more the realm of distribution formats like FLV, MPEG-4/H264 or WMV.
There are distribution codecs which use AVI as a container out there, but those are a different case.

How can I reduce the file size in Adobe Reader 9?

My wordpress isn't allowing me to upload files larger than 2MB. How do I resize my PDF in Adobe Reader 9 so that it is <2MB?
Thank you very much for the help!

In Acrobat, open a PDF file.
-Choose Document > Reduce File Size.
-Select Acrobat 8.0 And Later for file compatibility, and click OK.
When you choose the compatibility level, be aware that the newer the version of Acrobat that you choose, the smaller the file. If you choose compatibility with Acrobat 9, however, you should be sure that your intended audience does indeed have version 9 installed.
Name the modified file. Click Save to complete the process.
It is always a good idea to save a file using a different name so that you don't overwrite an unmodified file.
Acrobat automatically optimizes your PDF file, a process that may take a minute or two. Any anomalies are displayed in the Conversion Warnings window. If necessary, click OK to close the window.
Minimize the Acrobat window. View the size of the reduced file. The file size is smaller.
You can repeat steps stated above using different compatibility settings to see how they affect file size. note that some settings might actually increase the file size.
PDF Optimizer offers more opportunities to control quality trade-offs.
Choose File > Close to close your file.

How can I reduce the file size of my .cp project file?

I am working in CP3 and creating training programs via computer simulations. Generally I try to eliminate any unnecessary animation in my slide (use of scroll bars, drop down menus etc.) because these seemed to increase my file size. I do have audio narration on almost every slide and I know that this helps to bump up my size.
Here's what I found to be so odd.
I have to create a new training module and I simply opened one of my .CP projects and did a SAVE AS with a new file name. I reduced the number of slides from 25 to 3. The three slides I kept are the title slide, closing slide and one slide that I'll call a content slide that has the color for my highlight boxes and text formatting. (I keep the content slide so I can simply copy and paste the boxes as I need them.) I removed all the audio. Finally I saved the new project. Imagine my surprise when the new file is 96,333 KB with only 3 slides, no audio and no animation. This is almost the same size as the original file. I published my 3-slide project, thinking it might change the size, but that was wishful thinking.
I telelcommute from my home and I am required to check these files out of a secured document library each time I need to update them. The upload time is KILLING ME!
What am I doing wrong? The Information section shows the file size as 783.9KB which seems more in line with what I would expect.
Any help, as always is appreciated.

Hi BIMB,
Here's my guess, others can correct if I'm way off.
What you see as the file size under the Cp4 Storyboard View Information is what the published file size would be sans any unused pics, audio, or swfs. So it should be relatively small given you only have 3 slides in your project.
What you see as the 'save as' version reflects all of the pics, audio, and/or .swfs you still have in your project's library.
Now if you've actually removed the audio files and pics from the Cp Library, then I'm not sure.
Curious to know if this helps,
Keith

How can I reduce video file size?

I have a WMV file (4.6 MB) that has a bad sound track. I started a new Premiere project and placed the MP4 file, split the audio track, and used Audition to fix the problems with the sound.
Then I opened the file in Media Encoder (2014) and I've tried numerous settings to export the file as MP4, AVI, or WMV. My exported WMV is 40MB. The MP4 is 108MB. The AVI was over 1GB.
I've tried reducing the frame rate to 10fps. I've used various HD 720p presets. No matter what I do, the smallest file I've been able to create is 10 times the size of the original.
Clearly I'm doing something wrong.
I know a fair amount about audio, but very little about video. After several hours of searching online resources, all I have is more questions.
It's there a Media Encoder for Dummies section?
Thanks.

Thanks, Joost, but I see no setting for bandwidth. Here's what I see and the resulting (11 minute) file is 76 MB when the source file was less than 5MB. Output is down to 10fps and audio is mono and downsampled to AM-radio quality. Clearly I am not seeing something that I should see.

How can we reduce compares Database size in express edition

Data or page compression feature is not available in express edition so you cannot use this feature to help you.
You might be lucky to reclaim space from shrink operation but eventually data file will grow again. So your best bet is using licensed version.

The command is gone because iDVD has been discontinued by Apple. After Apple discontinued iDVD they removed the iDVD burning link from iMovie. I still use iDVD sometimes, only because I have an old copy.

Kodak Digital Camera QuickTime MOV Problems
After battling a number of serious problems with the videos taken by my new Kodak Digital Camera, I decided to write up this page so that anyone searching the web would find out the true answers without as much grief!
I’ve also made some other comments about my experience with the camera, in case anyone was considering buying a Kodak camera in the near future.
I bought the camera just before Christmas 2004 in the US. At the time of writing, it is a pretty good model for domestic use—about 5.2 megapixels, costing about US$400 (or AU$600 back here in Australia). From a company as reputable as Kodak, I expected no problems.
The first disappointing thing was that the spring inside the spring-loaded battery clip, inside the camera, came loose within days. It proved impossible to reattach it without completely dismantling the camera, which (despite my engineering qualifications) I was not willing to do. This would usually have been a warranty item, but Kodak’s warranty does not extend to other countries. I’ve since had to jam cardboard in to keep the battery clip engaged, and have taped the battery bay shut to avoid it opening accidentally when taking the camera out of the case. This works fine with the docking station (an extra AU$100!), but it means I can no longer charge the battery without the docking station (since you need to take it out to charge it). I was not impressed!
The camera takes good photos, and I have no complaint with that. The controls and camera menus are well-designed. The large display is excellent.
The EasyShare software is not as easy to use as it looks, has a habit of crashing, has a web update program that is always running in the background of Windows, and transferring images is nowhere as easy or quick as it should be. I’ve now uninstalled it completely, and simply copy the photos directly from the device. (If the camera memory is nearly full, and you just want to transfer the last few photos, then it’s impossible to use the EasyShare software to browse the camera’s photos without it actually downloading the whole lot through the USB cable—and it takes forever! Copying from the device directly doesn’t hit this bug.)
The capability to take video using the camera was a great attraction when I selected it, and, if it worked properly, it would make it quite a handy little camcorder in its own right. With a 512 MB memory card in it, over an hour of video can be recorded at Video-CD quality (320 x 240 24fps video, 8 kHz audio). It’s not full digital video, but it would still be a pretty good feature for a US$400 camera. If it worked.
The first disappointing thing about taking videos is that the optical zoom cannot be adjusted while the camera is recording. It can only be adjusted between video sequences. I don’t know why this restriction was made in the design.
The real problems, however, start when you try to do anything with the video clips captured by the camera. Kodak has chosen to capture the videos in QuickTime format. This is fine—QuickTime is, technically, excellent—except that there is no simple way to convert QuickTime MOV files to AVI or MPEG or VCD. The Kodak software comes with a QuickTime player, so you can see the video clips on the computer you installed the software on—and they look good. Problem is that you can’t just dump those MOV files onto your Video-CD creator (it will usually want AVI or MPEG files).
It takes some time to realise that Kodak have not even bothered to include any software with the camera that can convert these MOV files to a more useful format. This is a serious PR blunder, and anyone bitten by this is unlikely to go near the Kodak brand ever again.
After some web searching, owners of these cameras generally find that the best (only?) freeware solution to convert MOV to AVI is Bink and Smacker’s RADtools program.
RADtools is amazingly powerful for the price (i.e. free), but it hits two fundamental problems with Kodak Digital Camera MOV video files, that are the fault of the Kodak camera, not RADtools. (I know this because every other MOV converter hits the same problems—except one, as you will see below.)
The first problem is that the sound cannot be converted properly. When you convert any Kodak MOV files, there is an “aliasing” of the sound at the upper frequencies. This is a technical description—you get a whispery, tinny, C3PO type of echo to everything. It really destroys the quality of the video clips (especially bad when I am trying to capture priceless memories of my 4- and 7-year-old sons—I don’t want their voices destroyed for all time).
Every conversion program I tried ended up with the same audio problem. I concluded that it is something strange in the way the Kodak cameras store the MOV files.
Strangely enough, I noticed that the QuickTime player didn’t distort the audio like this. The audio sounds just fine through QuickTime. More on this shortly.
The second, more serious problem is that RADtools could not properly convert some of the video clips at all. (This problem only affected less than 10% of the clips I originally filmed, but most of those clips were very short—less than 20 seconds. It seems that the probability of this problem gets worse, the longer the clip.) RADtools would misreport the number of frames in the clip, and would stretch out a small number of frames of video (in slow motion) to match the length of the audio.
Again, I confirmed that this is a property of some of the MOV files stored by the camera. Other conversion tools also had problems with the same MOV clips.
After more angst, I found a number of websites in which frustrated owners of these Kodak cameras have reported the exact same problems.
It was only then that I discovered that QuickTime itself can convert MOV files to AVI. Believe it or not, it’s built into the QuickTime Player that Kodak supplies, or that you can download free from apple.com. The problem is that you can’t use it unless you pay Apple to upgrade to QuickTime Pro.
After realising that this would probably be the only way to get decent audio for these clips, I paid the AU$59 to Apple Australia to get the licence key that enables the extra “Pro” menu options in QuickTime.
Sure enough, you can “Export” any MOV file to a number of formats, including AVI. And guess what? The audio comes out fine!
So, the first piece of advice I can give is: pay Apple the US$29 (or whatever amount it is in your country) to upgrade QuickTime to QuickTime Pro.
From here, however, there are still a few snags to untangle.
The first is that the default settings for Exporting to AVI don’t give a great result. It defaults to the Cinepak codec, medium quality. This looks terrible compared to the original QuickTime movie. Even on maximum quality, that codec just doesn’t give good results.
I finally found that the best option is to use the Intel Indeo Video 4.4 codec, set on maximum quality. This creates AVI files that are 10 to 20 times larger than the original MOV files, but the quality is there. If (like me) you only want the AVI files so you can dump them into your Video-CD program, then you want to keep the quality as high as possible in this first step. The extra hard disk space is not really a concern. When your VCD program converts the AVI files to MPEG, it will compress them to the usual VCD size.
Now for the biggest snag: those problem MOV files are still a problem, even for QuickTime Pro. Unbelievably, these Kodak cameras are spitting out MOV files which have some sort of technical flaw in their data specifications. QuickTime is able to play them back fine—and that seems to be all that the Kodak engineers really checked. However, if QuickTime Pro tries to export them, then when the progress bar gets to the end, it never finishes. It just keeps going. If you check the output folder with Explorer, and keep hitting F5 to update the file listing, you can see the file getting bigger, and bigger, and bigger. It never stops.
That this happens even for QuickTime itself (the native format for these files) confirms that the problem is with the software built into these Kodak cameras. It would be nice it they issued a patch or a fix. I couldn’t find one.
Fortunately, there is a “workaround” for this problem. I found it when trolling the net trying to find solutions to all these problems. The workaround is to use QuickTime Pro’s cut and paste facility. Open the problem MOV file, then press Ctrl-A (the standard key combination for “select all”—in this case it selects the entire film clip, as you can see by the grey selection of frames at the bottom of the player). Then hit Ctrl-C (i.e. copy, which in this case copies all the frames, but not the incorrect data structure in the original MOV file). Now hit Ctrl-N (i.e. new, in this case a new MOV file or player). In this new player, press Ctrl-V (i.e. paste). Now you have a new version of the MOV file with the bad data structure exorcised. You can save this under a new name, but make sure you specify “Make movie self-contained”—otherwise, it will simply be a link to the original (bad) MOV file, which you are probably going to delete once you save the exorcised version. (You also cannot overwrite the original file, because it needs to access that to make the “self-contained” movie. You need to give it a slightly different name, save it “self-contained”, then delete the original and rename the new copy back to what you wanted it to be. A pain, I agree, but at least the **** thing works—finally!)
The exorcised MOV file can now be used to Export to AVI format. (I also keep all the MOV files on a separate CD, in case I want to reconvert them to a different format in the future. I figure it’s better keeping the exorcised ones than the haunted ones.)
So I hope that all this answers a few of your questions. No, you weren’t being incredibly stupid.

You can't change it, and I suspect few email providers would allow a file that big. Consider uploading it to a service like Dropbox, then email the link allowing the recipient to download it.
