Reducing Movie File Size

I have a 8 minute video shot in HD that when I export, it comes out to about 1.5 gb (not exact because I'm in the process of exporting it again and I can't get details at this moment). I need to imbed this onto a Keynote presentation for a graduation ceremony and I was wondering if anybody out there could give me a suggestion on what compression would be best to export this to. I'm asking because I usually play around with each compression format to get a good image/manageable file size, but, I'm short on time and don't have a lot of time to try different formats. Sadly, I don't remember what worked in the past. I think I used to export the full .mov file and then convert it using quicktime or something.
I'm hoping that I can get something small in size but in good quality to play on a large auditorium screen. The projector isn't as nice as a movie projector so I can sacrifice some quality but preferably not a lot.

Found a good solution, for those of you that are interested. After exporting to .mov, I just used quicktime to save as a HD 720p movie. Went from 1.9gb to about 310mb. Perfect for the ceremony and great size too.

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.

Reducing .mov file size?

I have a ten minute project finished in iMovie HD. I want to upload to Youtube in HD and need to get the finished file down to 300MB or so, but everytime it comes otu to 1.1GB. What are the best settings to create the smaller file size?
I did it once before, but don't know how ;-/.
Thanks.

Check out Karsten Schluter's website where he takes you through the best settings for iMovie to You Tube:

I have a .mov file that is 59 gigs. Is there a converter that can reduce the file size with minor resolution loss so I can import it into final cut express?

I have a .mov file that is 59 gigs. Is there a converter that can reduce the file size with minor resolution loss so I can import it into final cut express?

Open the file in QuickTime Player. Then do Tools > Show Movie Inspector. What does it say for Format and FPS?
At 59GB, I suspect you have either a 4 hour DV video or a 1+ hour video that was converted to Apple Intermediate Codec. If it's either of those, you can import it directly into FCE provided you select the appropriate Easy Setup first. Your clips have to match the properties of the Easy Setup you are using.
If it's neither DV or AIC then you need to convert it to one of those codecs. (QuickTime/DV or QuickTime/AIC) Many people in this forum rely on MPEG Streamclip (it's free and works great).

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.

Reducing MP4 File Size for online upload

I have a short HD video almost 1 GB in size (impossible to upload online). Is there an easy way to reduce the file size using IMovie or another program that I don't have to go out and buy?

I don't think you'll have too much success with this. Mpegs are already compressed files, so there's no real benefit to trying for further reduction. In some cases using compression software will make the resulting file larger than the original.
There are utilities that can be used to slice up a file into smaller parts that can then be reassembled. For example, Movie Cutter, SplitFuse, Split&Concat, MacAppStuff Pieces are a few. Look for them at VersionTracker or MacUpdate. Stuffit Deluxe is a commercial product that includes the ability to split and join multiple pieces of a file archive and has the benefit of being available on both Macs and PCs.
You can then split a large file into several smaller files to send via email or to upload to file server sites. Of course the recipient will need a compatible utility to join the pieces.

Photo Both video (.mov) file size in Lion

Photo Both in Lion saves videos (.mov) with double the file size of previous versions. I have verified by looking at a 30 second video created pre-Lion (2.1mb) and a new 30 second video created post-Lion (4.1mb) on the same MacBook Air. I have seen even more drastic file size increses on a newer MacBook Pro; more that 20mb for a video that used to be under 2mb.
There are no settings available in Photo Booth. And as stated in other threads there is no method in Mail to resize a video, this option is only available for images. The only functioning workaroud is to open the .mov file in Quicktime and then export for the web. This is OK, but the beauty of Photobooth and the Mail button within was the ability to just quickly fire off a video. Opening another app, exporting and then attaching to an email is no longer simple or beautiful.
Does anyone know why the filesizes have jumped up so drastically? More importantly, does anyone know how to get the file size of videos created in Photo Booth back under control so they can be emailed more easily?

UPDATE: Using any of the effects in photo booth videos greatly reduces the file size. This seems a bit contrary to what I would expect. Adding birds flying around my head cuts the video size in half. Sepia cuts down to 1/3. Black and white, the one that isnt a suprise, is less that 1/4 the file size of just plain old color.
Why can't I just have the nice small video files that Photo Booth used to save??

Have Tips On reducing .EXE File Size?

Hello,
Captivate exe file sizes are huge compared to comparable exe files produced by competitor software. I set my slide quality to Low, set swf conversion to 16 bit instead of 32 bit, set swf Size And Quality to 50%, and the .exe files are still huge. In fact, changing these settings made no difference to the file size.
Anyone have any tips on reducing the file size of the Captivate Exes, or do you know of any utility that can make .exe files smaller?
Thanks,
Mike

OK somewhere I got mixed up here.
So far as I know, this blig post from the Adobe Captivate Blog explains what is meant to work
http://blogs.adobe.com/captivate/2009/01/adding_rightclick_in_captivate.html
Check the list at the bottom of the page:-
1. Security Setting:   Ensure that the SWF you
published is in Flash Player's trusted path. If you are publishing to
default folder (%My Document%\My Adobe Captivate Project) then you do
not need worry about security settings as captivate automatically adds
that path into trusted path of flash player.
                               2. Disable accessibility: In order to make Right-click work you will need to disable Accessibility from
                               Adobe Captivate 4-> Preferences->Project->Publish settings->Enable Accessibility
                               3. Right-Click will not work in stand-alone SWF file.
                               4. PDF and AVI publish: Right-Click doesn’t work in PDF and AVI publish.
                               5. EXE publish: Right-Click work for AS2 EXE publish but not for AS3 EXE publish
                               6. Preview (F4/F8/F10): Right-Click work for AS2 movies but not for AS3 movies
                               7. Preview (F12, in Web Browser): Right-Click works for both AS2 & AS3.
                               8. SWF Publish (the standard one) : Works for both AS2 and AS3.
                               9. Flash Player Version: Right Click Doesn’t work for movie published Flash Player versions
                           earlier than 8.0
If you are complying with the suggestions here (AS 2 EXE?) then right-click is supposed to work. But I have a feeling I've missed something in what you've said ... or you said it in another post which I've not read.

ITunes Movies - File sizes and iPods

I searched to see if I could find an answer, but wasn't successful.
Question relates to if we can down-convert iTunes movie purchases to be more efficient on iPods? A downloaded movie (that plays beautifully on an Apple TV) is often over 1GB in file size. The kids have 8GB iPod Touch's and complain about movies taking up too much space.
Is there a way to reduce the file size for play on their iPods?
Thanks.

Which in my mind is an indicator that DRM is involved. I can select purchased movies and TV Shows and the option is not available - but I choose a home made movie and the option is available.
You are stuck with what you have.

Posting Again: How do you reduce a file size on a quicktime file?

I have a 16.9 meg movie in quicktime, and am trying to export it so I can upload a smaller version online. Whenever I try to export it using various quicktime settings, there's no audio on the exported file. I'm selecting Export from the File menu, then Standard Video Compression settings of H.264, optimized for streaming, most recent settings, quicktime movie to quicktime movie.
To reduce a movie, or shrink it, what are the best settings to use? Or even settings that work? I posted this a few days ago and there weren't any responses so I'm trying again. Please help.

I've been using MPeg Streamclip to export the files as a quicktime movie. And there is sound. But the thing is, the file sizes are huge. Last export was 160 megs...too big to put on a web page. So I'm interested in shrinking that. I tried ISquint, but it converts it into an MPeg movie, and I'd like to keep it as a quicktime file for the website. Whenever I export using Quicktime, and I've updated to the most current version, there's no sound. If anyone knows of a good way to reduce the file size, either using MPeg Streamclip, or any other shareware or freeware programs, please let me know.

A simple and free way of reducing PDF file size using Preview

Note: this is a copy and update of a 5 year old discussion in the Mac OS X 10.5 Leopard discussions which you can find here: https://discussions.apple.com/message/6109398#6109398
This is a simple and free solution I found to reduce the file size of PDFs in OS X, without the high cost and awful UI of Acrobat Pro, and with acceptable quality. I still use it every day, although I have Acrobat Pro as part of Adove Creative Cloud subscription.
Since quite a few people have found it useful and keep asking questions about the download location and destination of the filters, which have changed since 2007, I decided to write this update, and put it in this more current forum.
Here is how to install it:
Download the filters here: https://dl.dropboxusercontent.com/u/41548940/PDF%20compression%20filters%20%28Un zip%20and%20put%20in%20your%20Library%20folder%29.zip
Unzip the downloaded file and copy the filters in the appropriate location (see below).
Here is the appropriate location for the filters:
This assumes that your startup disk's name is "Macintosh HD". If it is different, just replace "Macintosh HD" with the name of your startup disk.
If you are running Lion or Mountain Lion (OS X 10.7.x or 10.8.x) then you should put the downloaded filters in "Macintosh HD/Library/PDF Services". This folder should already exist and contain files. Once you put the downloaded filters there, you should have for example one file with the following path:
"Macintosh HD/Library/PDF Services/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
If you are running an earlier vesion of OS X (10.6.x or earlier), then you should put the downloaded filters in "Macintosh HD/Library/Filters" and you should have for example one file with the following path:
"Macintosh HD/Library/Filters/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
Here is how to use it:
Open a PDF file using Apple's Preview app,
Choose Export (or Save As if you have on older version of Mac OS X) in the File menu,
Choose PDF as a format
In the "Quartz Filter" drop-down menu, choose a filter "Reduce to xxx dpi yyy quality"; "Reduce to 150 dpi average quality - STANDARD COMPRESSION" is a good trade-off between quality and file size
Here is how it works:
These are Quartz filters made with Apple Colorsinc Utility.
They do two things:
downsample images contained in a PDF to a target density such as 150 dpi,
enable JPEG compression for those images with a low or medium setting.
Which files does it work with?
It works with most PDF files. However:
It will generally work very well on unoptimized files such as scans made with the OS X scanning utility or PDFs produced via OS X printing dialog.
It will not further compress well-optimized (comrpessed) files and might create bigger files than the originals,
For some files it will create larger files than the originals. This can happen in particular when a PDF file contains other optomizations than image compression. There also seems to be a bug (reported to Apple) where in certain circumstances images in the target PDF are not JPEG compressed.
What to do if it does not work for a file (target PDF is too big or even larger than the original PDF)?
First,a good news: since you used a Save As or Export command, the original PDF is untouched.
You can try another filter for a smaller size at the expense of quality.
The year being 2013, it is now quite easy to send large files through the internet using Dropbox, yousendit.com, wetransfer.com etc. and you can use these services to send your original PDF file.
There are other ways of reducing the size of a PDF file, such as apps in the Mac App store, or online services such as the free and simple http://smallpdf.com
What else?
Feel free to use/distribute/package in any way you like.

Thanks ioscar.
The original link should be back online soon.
I believe this is a Dropbox error about the traffic generated by my Dropbox shared links.
I use Dropbox mainly for my business and I am pretty upset by this situation.
Since the filters themsemves are about 5KB, I doubt they are the cause for this Dropbox misbehavior!
Anyway, I submitted a support ticket to Dropbox, and hope everything will be back to normal very soon.
In the meantime, if you get the same error as ioscar when trying to download them, you can use the link in the blog posting he mentions.
This is out of topic, but for those interested, here is my understanding of what happened with Dropbox.
I did a few tests yesterday with large (up to 4GB) files and Dropbox shared links, trying to find the best way to send a 3 hour recording from French TV - French version of The Voice- to a friend's 5 year old son currently on vacation in Florida, and without access to French live or catch up TV services. One nice thing I found is that you can directly send the Dropbox download URL (the one from the Download button on the shared link page) to an AppleTV using AirFlick and it works well even for files with a large bitrate (except of course for the Dropbox maximum bandwidth per day limit!). Sadly, my Dropbox shared links were disabled before I could send anything to my friend.
I may have used a significant amount of bandwidth but nowhere near the 200GB/day limit of my Dropbox Pro account.
I see 2 possible reasons to Dropbox freaking out:
- My Dropbox Pro account is wronngly identified as a free account by Dropbox. Free Dropbox accounts have a 20GB/day limit, and it is possible that I reached this limit with my testing, I have a fast 200Mb/s internet access.
- Or Dropbox miscalculates used bandwidth, counting the total size of the file for every download begun, and I started a lot of downloads, and skipped to the end of the video a lot of times on my Apple TV.

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 do I reduce the file size of a pdf to email?

I have a 260 MB pdf file generated from Photoshop 6. I can't seem to reduce the size in Photoshop. Is there anyway to reduce the pdf outside of Photoshop? Thanks in advance for any help.

Hi Scott,
That's a pretty big PDF! You'll have to reduce it pretty dramatically to attach it to an email. But, you can use Acrobat to reduce the file size. Please see this video for pointers: https://acrobatusers.com/tutorials/how-to-compress-a-pdf-file
If you don't have Acrobat, you can try it for free for 30 days. For more information, see www.adobe.com/products/acrobat.html.
Best,
Sara
