I import mp4 1920X1080 - the file size is 320MB . I publish it as same mp4 and it takes 2GB . Why? Why is it that huge? HELP!

hi,
*Thank you for you response. *
*I found where to set the bit rate and it solved the problem. (the default
was very high...)*
Now it takes same space and the quality is the same as the original.
Thank you!

I have a few hundred duplicates in my iPhoto library, but the file sizes are different. So one is 1.3mb and one is 567kb. I want to delete the smaller ones, but short of comparing each duplicate, is there a way to do this?

I have a few hundred duplicates in my iPhoto library, but the file sizes are different. So one is 1.3mb and one is 567kb. I want to delete the smaller ones, but short of comparing each duplicate, is there a way to do this? I've been looking at Duplicate Annhilator but I don't think it can do it.
Thanks!

I just ran a test with iPhoto Library Manager, Duplicate Annihilator, iPhoto Duplicate Cleaner, Duplifinder and Photodedupo. I imported a folder of 5 photos into a test library 3 times, allowing iPhoto to import duplicates. I then ran the 5 photos thru resizer to reduce their jpeg compression but all other aspects of the file the same.
None of the duplicate removal apps found set that was reduced in the file resizer. That's probably due to the fact that the file creation date was being used as a criteria and the resized photo would have a different file creation date even though the Image Capture date was the same.
They all found the 3 regular duplicates and some of them would mark two and leave the 3rd unmarked. iPhoto Duplicate Cleaner can sort the found duplicates by file size but if the file was edited to get the reduced file size it might not be found as it would have a different file creation/modification date.
iPhoto Library Manage was able to find all duplicates and mark them as such if the file names were the same the the filename option was selected. Otherwise it also missed the modified, resized version. It allowed one to select the one photo to save before going to work on the library.
So if a photo has been reduced in image quality or pixel size it will not be considered a duplicate.

Why does the file size change when put into an iDVD project? And problems with dual layer discs...

I exported a short video of mine from Final Cut Express and the size of the file came out to 7.3 GB. When I put it into an iDVD project, it says that the file is only 800 MB. I tried just burning it onto a dual layer disc anyway to see if it might still burn at the original file size, but the disc came out unusable for some reason, and obviously hadn't been burned anywhere near full-capacity. So, I tried it again, and the exact same thing happened.
I guess my first question is: why is iDVD changing the size of the file? I want the quality to be the best it can be, so keeping it at 7.3 GB as opposed to 800 MB is rather important.
Secondly, why did the dual layer discs come out unusable? I've burned single layer discs before and they haven't been an issue. Also, I know for a fact that the drive can burn dual layer discs, so that isn't the issue.
Thanks in advance to anyone who can provide me with help on this issue.

Guessing here but it looks like you edited/exported an SD/DV sequence of about 30 min in FCE. DVD needs to be MPEG-2 so iDVD compresses the original file down to the size that you report.

The quality will be what the MPEG-2 compression and the software allow for. MPEG-2 is DVD standard .... there's no way around that.

Guessing again but it would seem that you burned a Data DVD instead of a Video DVD which would be unusable by a set-top player. As I said above you can't get around DVD standards.
If by any chance your video was HD originally you can try to go the Blu-Ray route using Roxio Toast or FCS 3 (discontinued) or FCP X. You will also need a Blu-Ray burner.

How do i reduce the file size of a picture?

I am trying to reduce the file size of a picture? It is 1.7MB and I need it to be smaller.
Help?

File -> Export
The two settings that most affect the filesize are Jpeg Quality and Size.
This User Tip

has details of the options in the Export dialogue.

I imported an hour of video into iMovie HD and cut it down to a 33 sec clip, and emptied the trash. When I save the project, the file size is 20Gb. How can I save just the 33 sec clip?

I imported an hour of video into iMovie HD and cut it down to a 33 sec clip, and emptied the trash. When I save the project, the file size is 20Gb. How can I save just the 33 sec clip?

Non-destructive editing is an important feature of iMovie HD 6.
iMovie preserves the entire copy of every clip you place into your movie in case you change your mind at a later stage.
So, if you have cut out one minute from a 45 minute clip, iMovie will have stored two complete copies of that clip. This is why is helps to set import as 3-5 minute clips rather than one huge chunk. As DV runs at 13GB per hour your project files can get very big.
One workaround is to complete the editing of a section of the movie, then export that to Quicktime: highlight the clip/s, choose Share-Quicktime, turn on Share selected clips only, and choose Full Quality from the pop-ip menu.
Once you have saved the stand-alone clip to your hard drive, you can re-import it into your project using the File/Import command, and delete the original long clip/s from the project.

Can I find out the file size of tracks before I import a CD?

My husband is an audiophile, we listen to classical music. (Although I indulge in some Beatles and other music on occassion.) Is there a way to find out how large the file sizes for each track will be for importing with Apple Lossless versus AAC, as well as different bit rates, before I import the CD onto the computer? I'd like to know how much disk space a classical CD is going to take up before I commit to using up however much of my hard drive it might take. I appreciate thoughts and ideas on the subject.
Cheers.

I think a rule of thumb is what you're looking for.
Full bandwidth CD audio (AIFF): about 10 MB/min
Apple Lossless: about 5 MB/min
MP3 @ 256k: about 2 MB/min
MP3 @ 128k: about 1 MB/min
Of course the MP3 file size is exactly linear with bit rate.
As for sound quality:
Apple Lossless is, as the name says, lossless.
MP3 @128k: fine for listening in the car or the kitchen etc. If you have an audiophile sound system, this will remind you why you spent all that money.
MP3 @256K: barely distinguishable from CD on very good equipment.
MP3 @320K: probably not distinguishable from CD.
I presume that since you're talking about importing classical CDs these are ones you own. Remember you can always do it again if you need higher fidelity or if better technology comes out. I import most CDs at 128k, since most of my MP3 listening is in the car, or walking, or as background. And I can always play the CD if I want to sit and listen.
The logic for purchased music is totally different -- you probably won't get to upgrade that without buying it some different way. So buying 128k MP3s (or AACs) is something you'll probably regret later. Buying 256k MP3s is a lot less problematic.

Why does dragging an imported video into a project reduce the file size by half?

I used a Canon Vixia HV40 to import 1 hour of HD video filmed using 24F and cina mode. My import and project properties were as follows:widescreen (16x9, 24F, cinema, import size = full, original size.
The specifications for the imported file are as follows/:
Size: 22.12GB
Dimensons: 1920 x 1080
Codec: Apple Intermediate Codec, Linear PCM
Color Profile: HD(1-1-1)
Audio Channels: 2
Total Bit Rate: 47,113
When I drag the imported file into a new project, the resulting .mov file has the following specifications:
Size: 9.67GB (approx half the size)
Dimensions 1920 x 1080 (same)
Codec: H.264, AAC (different)
Color Profile: HS(1-1-1) (same)
Audio Channels: 2 (same)
Total Bit Rate: 20,607 (approx half)
What causes the file size reduction and bit rate reduction? Is it a result of the different codec? Is there any corresponding loss of video quality that results from the conversion?
Thanks for your answers in advance.

Thanks a lot for your quick and detailed response!
Maximum image quality and file size are not the same thing, for a start.
Yes, but with JPG's they tend to be correlated, aren't they?
When you view a photo in iPhoto it's a composite of the original and the decisions recorded, and applied live as you view.
Oh, I always thought iPhoto makes a copy of the orginial and modfies that ...
If you want to use that photo for something then you have to export it. This make a new file with your photo in it. When you export you have a lot of options - including ones that will make the filesize bigger than the original. This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue.
Ah, that is cool. That solves my problem.
If you use drag and drop from the iPhoto Window that's a form of exporting too -but you have no options there. You get the iPhoto Preview. That's a 'handy-good-enough-for-most-things version of the shot. If you want more options use the export command.
That's what I tripped over. (I used the email feature from within iPhoto for a quick sharing ...)
Thanks, G.

How can I keep tabs on the file size when importing from the Event Library into a Project? I want to ensure the movie will fit onto a 4.7Gb disc?

How can I keep tabs on the file size when importing from the Event Library into a Project? I want to ensure the movie will fit onto a 4.7Gb disc?

iDVD does not care about file sizes, as it compresses the file to the standard DVD format of mpeg2.
It only cares about length i.e. max 2 hours including titles etc.
iDVD encoding settings:
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned abo
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

Thanks. I do not have the experience on burning discs from iMovie for the movie after editing (ie for video discs players). It seems that i cannot find the relevant command in the tool bar for this purpsoe. Would you please show me the way?
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.

You have mentioned about Handbrake as a converter. What is the RF no. (under Constant Quality) meant? It seems that the smaller the no. is, the better quality will be. What is the optimal no.? or should we use the Average Bitrate? Again, what is the best rate? Furthermore, which format is more suitable or the best: H264 or mpeg 2/4?
I don't know what RF means. When I have used HandBrake, I've used presets that apply to what I want to do, so I don't know the meaning of each individual setting. However, it appears that many of them are listed in the HandBrake User's Guide that is linked from the Help menu in the program:

For iMac, except iMovie, what other software is the best for the amateur? I have read Photoshop. Can this support m2ts files and user friendly?
Photoshop is not amateur-level software, and although it can edit a video, it cannot burn a DVD. Unfortunately, because I still use iMovie, I haven't tried anything else. You might want to read the reviews of various DVD-burning applications in the Mac App Store.
And maybe another forum member will jump in and help us here!

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.

Export QuickTime file with new audio and maintain the file size and quality as the original.

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for the client and deliver them as the same QuickTime file but with the clean audio and keep the file size close to the original and not have quality loss in the image?
If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size. They did request that they be Quicktime MOV files though so that is a must.
I don't see this as an option in the codecs in the export settings in PP, but is there a way to export as ProRes or another MAC native codec that will save them from having to convert it on their end? I am on a PC with Adobe CS5.5 so I am not too familiar with MACs, but from what I understand they would need to convert the files if I sent them straight out of the camera.
I found some related search results for this but they pertained to "Best quality" for export. I am not sure how the varying options work but I don't want to create files that are considerably larger, just not less quality.
If anyone has experience with this it would be greatly appreciated.
Thanks,
Cole

Here's the workflow: I imported the video footage into iMovie '08 and did my edits. Then I exported it (share) to my desktop with compression set @ 740 X 480. Then I used QuickTime Pro to fix the audio track. The file plays perfectly with both audio tracks working. It's a QuickTime file (.mov).
I hope this jars any replies as to why the file when uploaded to my iWeb gallery drops the second audio track.
Hmm,

How do I reduce the file size of my pictures

I am running out of space on my hard drive and notice that my iphoto library contains over 5000 pictures and is about 15GB. This is about 3MB per picture. I checked and lots are over 10MB. Most pictures I only print in 10x15, the largest i ever printed was A4 sized. I guess i don't need to keep such large files. These cameras are now set to make pictures with too many pixels I guess...
does anyone know of a way to reduce the size of all my picture files?
thanks

1. Reducing the file sizes of your pictures will not just reduce their quality when you print, it wll also negatively affect their quality no matter how you view them. Remember the screen quality on your next mac will be better than this one, and even more so on the one after.
2. The simplest solution to a size issue is to store the Library on an external disk, You can do this with iTunes and iMovie too.
3. If you really want to reduce the quality of your photos then there is no way to do that in iPhoto. Here's what you'd have to do:
Export the Pics from iPhoto (File -> Export) and in the Export dialogue make your choices on Jpeg Quality (the amount of compression used) and size (the dimensions)
Delete the pics from iPhoto
Import the ones who have exported back to iPhoto.
Give away your camera and get a lower quality one
