Compare file size .mov vs .mp4

I have an iMovie that I exported to .mov with expert settings: 32KHz audio, 24 fps, 480x360 and it gave a file about 300 mb ( a tad over 6 min). I also have some videos from a subscription at Luminous-Landscape that are mp4. As far as I can tell they are the same parameters. BUT, one of them, for example, is 27 min and about 147 mb! Much smaller proprotionally!
I noticed a much smaller bit rate while viewing the longer duration video compared to mine. Something in that? Is it that it is mp4 and mine is mov?
Is there a good place to go to decipher the Expert Settings meanings and practice?
Thanks...
Rick

... you haven't told us, which CODEC you used for your export.. (?)
.mov is just a container, a wrapper around mp4, h263, sorenson, h264, mp4.. whatever.. (even mp3, pic, qtvr...)
the container doesn't add that much of data to a file..
24fps is .. 'exotic', when it comes to iMovie, which doesn't support such a framerate, and when it comes to computer display, 24fps again is less optimal .. it is a fps from the film business.. you get much better (=in terms of quality) results, using the original or half of the framerate of your source ...
with all respect, I mostly doubt a 30min video of only 150MB size ... please check the settings again ...
when it comes to small file sizes, I lately stumbled into a nice variation of the h264 codec, have a look on my website:
http://karsten.schluter.googlepages.com/apowerfulcodec
and if you prefer mp4, use the free encoder iSquint, esp for lower bitrates, it offers a (much) better pic quality than QT's mpeg4 encoder ... (a few infos on my other site, click here)

"file is not compatible when import assets in dvd studio pro, my file are .mov and .mp4, what is the problem?

i have a MacBook Pro v. 10.7.5, also have dvd studio pro 4.2.2
I have a file exported from final cut v. 7, using quick time movie option, it created a file with .mov. When I import to dvd studio pro, I have an error
message " file is not compatible". shall I export again using different parm? settings? thanks for the help in advance.

Thanks, Russ. I had my problem resolved by re-creating file from Final Cut using the "Video Format" as "MPEG-4 improved" instead of "H.264" before.
My orginial source is a dvd came from Taiwan, I used software 'Handbrake' to convert it to MPEG-4. Input to Final Cut to edit it. Exported out with H.264 as Video Format, wishing to improve the image quality but run into 'file impaitable' when import to DVD SP.
Now. I exported out Final Cut using the following parms, pictures quality is not bad.
1. File format = MP4
2. Image size= 1280x720 HD
3. frame rate = 30
4. video format = MPEG-4 Improved
hope this help people who might run into same problem. I never use the Compressor, will try it next time. thanks Russ.

Urgent:Comparing file size and file hashcode

Hi i am developing an EJB in which I have to dynamically pick the filename,filesize and hashcode of the file.
In case filename exists then it should check for file size and hashcode of the file. if both of these are equal then the processing should stop.
Could anyone provide some help in comparing filesize and hashcode of the file with itself.
Regards
Abhi

read the [File API|http://java.sun.com/javase/6/docs/api/java/io/File.html] .
The file size is a long. and the hashCode is an int. [compare them - they are primitives|http://java.sun.com/docs/books/tutorial/java/nutsandbolts/operators.html]

Is there a file size limit on mp4s that can be imported to iTunes 11.1.3?

I've recently upgraded iTunes to 11.1.3, and finding that if I import video files, not all of them will actually import. They're all using a H.264, AAC, MPEG-4 ODSM, MPEG-4 SDSM codec, but the sizes are varying from 20mb on the low end to 200mb on the high end. And it appears the larger file sizes aren't being imported. This has worked fine on 11.0 and earlier, so I don't understand why these files won't import.

I have put on things up to 2GB so far. No issues.
Could be your USB port. Are you sure you are using a 2.0 port (and not one connected via a Hub)?

VI revision history numbers match, but file sizes differ.

Hi all,
I am using LabView 7.0. I am trying to create a utility that compares the VIs on two different computers to make sure that the VIs distributed on both systems are the same. I tried accessing the Revision History number to compare the two files, but the execution was very slow because it is remotely opening VIs to access the property node and I am analyzing 100's or thousands of files. I then tried to compare the files by file size using the File/Directory Info.vi and noticed that many of the files that had the same revision history number had different file sizes. What may be causing these file size differences when the revision numbers indicate that they are the same? I do not believe that anyone has modified the revision history numbers for any of the VIs manually. Also, is there be a better method of comparing the files than what I am doing?
Thanks in advance!

Hi,
Thanks for your responses. I investigated the problem some more and it looks like the file size differences are caused when someone recompiles the VIs. I used the "compare VI" utility to compare VIs with different file sizes and matching revision numbers and found zero differences. So i ran this experiment:
1) I then created two identicle copies of a VI, making sure that the file sizes matched.
2) When I forced a recompile on one of them (Ctrl+Run Button) and saved the changes, the file size changed!
3) I went through and used the "compare VI" utility to compare the two files and there were zero differences and both had the same revision number.
I guess the revision number only increments when you make some changes to the VI, becuase I did not have to change anything to get the file size to change, I just recompiled and saved.
I still have the problem of compiling a list of revision numbers however. I am happy with the results of my VI except for how long it takes to execute. My VI simply opens a VI reference, accesses the revision number through the property node, and closes the reference for the VI. This is done recursively for all of the VIs in a directory on a remote computer and takes about 25min for ~500 VIs to complete. I guess it takes so long because I am remotely opening all of those VI front panels over the network. Comparing file sizes is much quicker (20 sec to execute) but it would be nice to have both the revision number and the file sizes to determine the state of the code on a particular machine. Is there any other method of getting the revision number that might be quicker?
Thanks again for your help!

Newbie Question: F4V file size is huge compared to .mov

Hi, I have a 28 MB .mov that I want to embed into a web page using Flash / Media Encoder. In Media Encoder settings it says the estimated file size will be 2486MB. Am I missing something? It is a long video of a ppt presentation (about 1 hour). I'm not concerned about quality, just file size.
Thanks!!!

The simplest and most overlooked is to change the background
image quality from "High" to "Standard" - this effectively does
just what you mentioned, decreasing color depth. This can be done
by selecting the slide(s) and using the "Slide > Video Quality"
menu for the change. The highest quality isn't always the default,
but check it on your slides to see. If the project is a converted
Power Point, for instance, the "High" quality setting is the
default...
If you notice "bleeding" of background colors, you may have
to increase the color depth (slide "video quality") on the affected
slide, to cure the problem.
Regarding your reference to "best practice", I recommend a
DevCenter article written by Dave Mozealous who was at that time a
staffer for the Macromedia Captivate team.
The
link is right here
Hope this helps get you sorted!
Some final personal thoughts:
First, since you appear to be a Flashie, keep in mind that
images in Captivate are stored, edited, and displayed as bitmaps,
which are much larger files then the vector-graphics you have
worked with in Flash.
Second,
any image of 1024 X 744 is going to be real -
real - big; and you are setting that as the size for every
background in your Captivate project. Sometimes that cannot be
avoided, but often people create large Captivate projects simply
because they haven't used the product long enough to realize what
problems that can cause. So if you can work with a smaller pixel
size for your projects, by all means, do so.

Need to export Movie to Quicktime Movie w/ similar file size and quality.

Let me preface in that I am not in the video editing profession. Many times I have exported my work to the professionals. I'm sure knowing what you're doing is half of the battle. Here is my dilemma. First, I'm using Quicktime pro just to add a text track to the movie. I then save the file as what Quicktime pro calls Movie .mov. This looks good and has the quality of the original .mov and the small data size. However, no other player than quicktime will recognize the text track. I then tried exporting from Movie to quicktime movie format (still .mov, can anyone explain the difference of the two .mov types???), but I find that the image quality is poor. Yet, in the quicktime format other players (except windows media player) recognize the text track. By poor quality I mean that I think what I have is the blocking effect. I assume that this is due to the bitrate being to low. Again, I would like to keep the file size low and managable for data storage and downloading purposes. I was hoping that in the end all video players would be able to have no issues.
My current file sized are all less than 1MB and are of good quality.
Just adding a small test track the Movie .mov is still less than 1MB
The size of the image is 512x512
I should also say that I'm a PC user with a quicktime pro windows version. I'm sure that doesn't help me one bit!! However, I believe my issues are more with the fact that I'm not experienced in compressing files and knowing exactly the right settings.
Here is what I've tried thus far. Movie to quicktime movie
H264 codec
Current for fps (Which is in the original is 8fps)
Key frames automatic
frame reordering checked
I've tried Automatic data rate and setting the bit rate, even at 2000kbps (the quality is low). My original movie with the highest kbps is only 1151kbps and has no artifacts
encoding Best quality multi-pass
custom size 512x512
deinterlace checked

am i correct that this 'my photo stream' process is not removing any image data?
Yes, as long as you have iPhoto's iCloud preference pane configures as follows:
You're be getting the full image file, pixel dimensions, etc. which is essentially a bit by bit copy of the photo on the Phone.
When you add tags and other metadata and export the file out of iPhoto as a jpeg with the checkboxes selected to include that metadata there will be some image compression. However, if one chooses High or even Medium JPEG Quality one will be hard pressed to detect any image degradation unless printing very, large prints or otherwise displaying the image at a very, large size.
I ran a test on a 1.4 MB photo from my iPhone and compared the original to two exports, one at High and the other at Medium JPEG Quality and got these results:

Is it best to upload HD movies from a camcorder to iMovie or iPhoto. iMovie gives the option for very large file sizes - presumably it is best to use this file size because the HD movie is then at its best quality?

Is it best to upload hd movie to iPhoto or iMovie? iMovie seems to store the movie in much larger files - presumably this is preferable as a larger file is better quality?

Generally it is if you're comparing identical compressors & resolutions but there's something else happening here. If you're worried about quality degrading; check the original file details on the camera (or card) either with Get Info or by opening in QuickTime and showing info. You should find the iPhoto version (reveal in a Finder) is a straight copy. You can't really increase image quality of a movie (barring a few tricks) by increasing file size but Apple editing products create a more "scrub-able" intermediate file which is quite large.
Good luck and happy editing.

Maximum file size for export into MP4?

Hello,
I am not able to export 2 hour HD video into standard MP4 file. It seems that reaching 100% export algorithm gets into loop. I was waiting for hours and still had seen progress at exactly 100% with final file size on hard disk to be 0 bytes. I am using CS5 on MAC OS X. I had to split my timeline to 2 parts and to export them separately (which is embarrasing). Is there something like maximum file size for export? I guess that 2h video would have about 25-35GB.
Thank you
jiri

You are right.
So I am running AP Pro 5.0.4, Adobe Media Encoder 5.0.1.0 (64bit). Operating system Mac OS X ver 10.7.3. All applications are up to date.
MacBook Pro Intel i5 2.53GB, 8GB RAM, nVidia GT 330M 256 MB, 500GB HDD
Video is 1920x1080 (AVCHD) 25fps in a .MTS container (major part of timeline), 1280x720 30fps in .MOV container (2mins), Still images 4000x3000 in .JPG
No error message is generated during export - everything finishes without any problem...just file created has 0 byte size (as described above).
This is my largest video project (1h 54min) I dont have any other problem with other projects.
I dont run any other special software, at the moment of export all usual applications are closed so that MacBook "power" can go to Media Encoder. No codecs installed, using VLC Player or Quick Time.
Attached please find printscreen from Export settings (AP Pro). Writing this ppost I tried to export only the first 4mins from timeline where all kind of media is used...and it was OK.
As a next step I will try to export (same settings) 1h 30mins as I still believe problem comes with length of video exported.
Let me know your opinion

With iMovie 10 how do I change the movie file size and type.

I have recently upgraded to iMovie 10. It takes some getting used to but I think I will like the new product. After creating my first few movies and trying to upload them to dropbox, it is taking a long time. Comparing the files to ones created in the previous version they are larger, and I need to know how we adjust the file size to the device the movies will be used for. I don't need high resolution files. It looks like you can change the size in file for share but still a large file and only compatible with Mac and PC others are greyed out. Files are much larger than the files generated in the old version.
Thanks any help will be appreciated.

This is one of the areas where the options have been reduced compared to iMovie 9. If you share to File, you should have Large (540p) and SD (480p) options in addition to the HD ones.
I'm not sure exactly which menu it is where you are finding greyed-out options.
What is the native format of the movie you are saving?
If you can't share directly into the format you want you should be able to post-process the shared file with a third-party app.

What is the max mp4 file size?

Does anyone know what the max mp4 file size that can be imported into iTunes for sync with ATV is?

RichSolNuv wrote:
I got HandBrake to work. What settings do you recomment for ATV? When I used the Apple Tv setting it worked pretty quick and I could view the file in iTunes, but it would not import into ATV. I got a message saying it was not playable on ATV. The "Normal" setting (h.264) seems to work good. I did a few minutes of a movie and it looks good and works with ATV, but it seems to take a lot longer (hours).
With Handbrake 0.9.1, always select "Apple TV" under the "Presents" column on the right side of the window. When you say it is "not playable on ATV" do you mean by streaming or syncing or both?

MP4 Merge or Join Files Problem. MP4 Maximum File Size?

I just came back from vacation with my girlfriend, and shot a bunch of home movies with my Canon 5d Mark II. The files created by the camera are MP4's.
There are a dozen of files in total and each one is around 1 GB at 720p.
What I want to do now is merge them together into one file. I have Quicktime Pro 7 and basically have been copying them all into one file, but once I try to copy the 8th file/chapter into the cumulative 7 previous files that are now in one continuos file, it doesn't really add anything.
Is it not working because there is a limit on the file size of the file of an MP4? How can I make sure I merge all the files into one? Any help would be greatly appreciated.

couldn't figure it out.

Saving project as MP4 file or .mov file

I want to burn my finished project as a DVD but my burning program needs it to be in a .mov or MP4 format. Can I save my project as such??

kevinbwatkins
Thanks for the reply.
The project file is the project.prel. You cannot change the project file (project.prel file) into a project.mp4 or project.mov file.
But, what is possible is to export the Timeline content of that project.prel file to a file whose format has a .mp4 or .mov file extension.
For Premiere Elements 11 on Windows 7, 8, or 8.1 64 bit, I would suggest
for the .mp4
Publish+Share/Computer/AVCHD with Presets = MP4 NTSC DV Widescreen - using default export settings
for the .mov
Publish+Share/Computer/QuickTime with Presets = NTSC DV 16:9 - using default export settings
If you have a HD source on your Timeline and your destination is a DVD-VIDEO widescreen on DVD disc, you forced into the
properties of the DVD-VIDEO product, namely 720 x 480 16:9 @ 29.97 interlaced frames per second (with 16:9 flag stretching
the 720 x 480 to 856 x 480 for display after encoding).
But, if you have a HD source in this project that just produced the DVD-VIDEO widescreen on DVD disc, you can opt to export
a file with the same resolution as the DVD or export to a file with a resolution comparable to the HD source. Please clarify and
we can fine tune the suggested export setting accordingly.
Thank you.

MP4/H264 file sizes very different

I seem to have the problem that when I convert files from AVI to MP4 or H264 they become remain rather large.
I converted a movie of 124 minutes to H264 and the file is 494 MB, while I also have a 154 minute movie which is only 3352 MB. In itunes info it says the 124 minute movie is low complexity h.264 320x240 film at bit rate 64 kbps (total bit rate 539 kbps). It is 494 MB or 3.9 MB/min
the 154 minute movie info gives low complexity MPEG-4 320x240 film at bit rate 63 kbps (total bit rate 313 kbps). It is 352 MB or 2.3 MB/min
I am using total video converter to convert, I leave all the settings at default, I just select H264 and change the dimensions to 320x240. Does anyone have any idea how i can get the h.264 or mpeg-4 filesto be smaller??

H.264 is higher quality than MP4, therefore larger file size.

Importing iPhone movies increases file size 3-4x

I imported clips from various sources into iMovie11, then I compared the files in the iMovie Events folder to the original files.
1. AVI movies are identical to the original files (file size and picture size - 640x480), regardless if I select "large 960x540" or "full size" when importing. So far so good.
2. However, Movies that were taken by iPhone 4 (MOV, original picture size 1280x720) end up 3-6x larger.
    2.1. If I select "full size" when importing, then the new file size is 6x larger than the original. (Picture size same as original, as expected.)
    2.2. If I select "large 960x540" then the new file size is still 3x larger than original. (Picture size shrinks to 960x540, as expected).
3. Same experiment with iPhone3 movies (MOV, original picture size 640x480)
    3.1 If I select "full size" then the file size is 3.5x larger than original.
    3.2 If I select "large 960x540" then the file size stays the same.
   (Picture size stays the same, 640x480 as expected in both cases.)
Now this is somehow consistent with the changes in movie format and data rate:
- In the cases 1 and 3.2 above, nothing changes from original to new (AVI format "motion jpeg open dml", MOV format "h.264").
- In the case 2 and 3.1, format changes from "h.264" to "Apple intermediary codec" and data rate goes up by a factor of 6 and 4, respectively.
FPS stays the same in all cases.
Can someone explain why it iMovie does this.
No segments of the new clips are duplicated, and they are not padded with gray or garbage like I've seen in other posts.
Thanks in advance

Motion JPEG is already an i-frame codec like DV or AIC so there is no advantage to converting to AIC. Each frame is a compressed JPEG.
I have some Motion JPEG that I received from a service that digitized some old 8MM film for me in 1080P. The Motion JPEG worked fine in iMovie.
The iPhone 3 created h.264 in smaller dimensions, like 640x480 (although I can't remember for sure). With smaller h.264 files, your Mac may have the processor power and memory to convert the h.264 on the fly as you render. For larger h.264 files like 720P and 1080P, most Macs do not have enough power, so you are better off converting to AIC.
So with the iPhone 3, you can make the choice yourself. You can convert them if you see a performance issue. Otherwise, edit them as is. To convert them, right-click on the Event, and choose "Optimize Media".
