H.264 file size

I have an Aiptek GoHD camcorder. (I thought I would work with this first before jumping into a HDD 1080 camcorder later this year) The quality of the video is remarkably good given the price of the device. The compression format is H.264 MPEG-4 at 1280 by 720. The file sizes are surprisingly svelte at about 25Mbyte per minute. I can take the SD card out of the camera, place it in my card reader and transfer it to my mac pro as .mov files that I can then import into iMovie08 without a problem. It converts them to Appple Intermediat Codec for editing purposes which of course balloons the file size. When I export the movie using quicktime, I am using the following settings:
Size: 1280x720
Compression type: H.264
Frame rate: Current
Key frames: Every 24 (Frame reordering check box selected)
Compressor quality : Medium (Faster encode check box selected)
Data Rate:: Automatic
This results in final file sizes that remain in the range of 100Mbytes per minute (or larger!)in spite of using the "medium" quality. I am not adding any effects except for a few titles. I am pretty frugal about what I want to record with the camcorder. All I really want to do is import 5-10 clips (of about 1-3 minutes in duration each) into iMovie, chain them together beginning to end and export it back to the hard drive as one movie in the same format in which the .mov files were originally recorded. My questions are:
Is the inefficent encoding a result of some setting that I have chosen incorrectly?
Is the inefficient encoding just a limitation of iMovie and would I get more efficient encoding if I went to FCE4? (I would rather not have to pony up for the pro version of Final Cut to get the "compressor" function but would consider it if I knew it would do the trick)
Would I be better off getting a hardware based encoder for the Mac (if such a creature exists) since the hardware based encoder for the Aiptek does such a nice job?
I appreciate any help!

Is the inefficent encoding a result of some setting that I have chosen incorrectly?
If by your question you are referring the the difference between source data rate and final target data rate, the you problem is in your settings. File size s directly proportional to your total combined data rate per unit of time. Selecting an "Automatic" video data rate tells QT to use as high a data rate as is it thinks is necessary. You can, instead, simply limit your final total combined data rate (i.e., Audio + Video) to that of your source or approximately 25 MB/M.

WMV to h.264 files size issues

I am using the Flip 4 Mac to view my WMVs with QT Pro 7. I want to export them to H.264 (or other MAC friendly format), but the new file has a size thats about 3x larger than the WMV file. Example a 233meg WMV file went to a 779meg file in the h.264 format. I would us iSquint or Podner but I do not want to reduce a 640x480 res to the smaller size of 320x240. Any ideas on how convert WMV Files and not lose any of the res, quality, and keep the files size about the same or smaller.

Trucker (does that mean you drive trucks?) I did for thirty years and am glad to be seeing the world from a 19 monitor as opposed to a huge windshield.
If the files play (via the flip4mac component) why not just leave them alone?
Any time you export, format to format or container to container, you introduce artifacts and could be adding to the file size by not using the source compression scheme.
Many WMP files use very low audio quality settings. Have you opened some of your exports and used the Movie Info window to compare settings?
H.264 has amazing video playback qualities and a 320X240 export can be viewed at "double size" without so much of a penalty to video quality.
Check the audio settings at export, too. Try to match the original source file settings.

With Premiere elements 11, when Publish/Share (saving) a finished video, selecting H.264 .mov file type, what are the recommended Codec and Aspect settings for a crisp video and a small file size?

With Premiere Elements 11, when Publish/Share (saving) a finished video, selecting H.264 .mov file type, what are the recommended Aspect and Codec settings , for a crisp video with a small file size?

We will customize a very detailed reply, but
(a) What are the properties of your source media?
(b) What did you or the program set as the project preset to match the properties of the source media?
(c) What specific requirements do you have for this H.264.mov export file?
File size can be a compromise between bitrate, file size, and quality.

MPEG -2 Blu-Ray more accurate file size reading in Encore than H.264 Blu-Ray???

Hi,
I just read on Kenstone.com that if you encode a MPEG-2 Blu-Ray instead of an H.264 Blu-Ray, Encore will give you a much closer and more accurate file size reading.
Is this true?
Encore CS 5.1

They are all guesses anyway.
H264 will get you more on the disc, as it is a much more efficient codec. Same quality in MPEG-2 will be twice the size, roughly.

Rendering AVCHD files to H.264 causes file size to go up!!

Hi everyone,
I have a Sony HDR-SR11 camcorder that produces files in AVCHD format (.mts file extension). The camera natively produces file which are approx 100mb for every 1 min of video (1440x1080 setting). My issues is that when I add files to the timeline and then render them in Premiere Elements 7 using the H.264 1440x1080i format (creates a M2T file) the file size actually doubles (1 min is now approx 200mb). I'm only bringing the files into PRE 7 so I can add transitions, but I cannot afford the disk space if the program will double each videos size.
Is there a different setting I should be using to just do basic editing and not change the source quality? I know the camera adds significant compression to the file, but why would it grow in size when I render.
Any help is greatly appreciated.
Mark

Update:
If I go in the Share Tab and click the advanced button I am able to fine tune my rendering settings. I found that changing the Bitrate Settings on the video tab will allow me reduce the file size. The default settings is 21 Mbps for both target and Max, I think it is WAY higher than the Sony Camcorder does natively so that is why the file size was growing??? is this correct?
Anyways, changing the Maximum Bitrate slider to about 10.1 Mbps gave me a file size equal to the original file from the Sony camcorder. The quality looks a tad softer than the original, but it's really hard to tell.
Anyone know if this is the solution to the problem described above? And, anyone know what bitrate these Sony HD cams output normally?

Error exporting h.264 mp4 with certain file size.

I have tried many times exporting my sequence with h.264 at file size around 5GB. It's a 21 minutes video and when I play them in any players (MPC, QuickTIme) they all stop playing at 16:30 - about 4.3 GB point in the file.
Playback in Premiere Pro is fine. The rendering went smoothly.
I exported with 36mbps, and Max 40mbps, Profile 5.1. 1920x1080. (Using Vista)
Later for experiment, I export it in 34mbps, and the point where the file fails to play is pushed back about 5 seconds - still around the 4.3 GB point. So I guess I can't export h.264 with file size larger than around 4.3 GB?
Any suggestions? Would appreciate any help.
Thanks

Did you export your video under 32bit operating system? How about the codec, did you use "h.264" or "h.264 Blueray".
I can't use "h.264 Blueray" because it won't let me render 30fps. And what's your audio codec? AAC?
I just tried to play it on a 64bit linux, no luck. Gave me a set of errors when it passed the 4GB point.

DivX to H.264 -- Any way to control for file size?

Hi there,
I'm converting DivX files that my digital camera uses to H.264 files. I'm using MPEG Streamclip to do this.
It's working fine, but results in much larger files. For example, a 23.4MB DivX AVI file converts to a 89.6MB H.264 MP4 file. A 91.4MB DivX AVI file converts to a 414.2MB H.264 MP4 file.
Is there any way to convert these using H.264 without sacrificing quality and without resulting in such large files? MP4 files work with Quicktime, iMovie and (under Leopard) the Finder much better than DivX files do. Any advice?
Thanks in advance,
Mike

When you are playing a DixX file have a look at the bitrates - IIRC that is a mix of video (most of it) and audio codecs. Say it says 1000 kb/sec. If you open the file in (freebie) MPEG Streamclip and export to MPEG-4 selecting the iPod setting 320X240 you will get a 700 kb/sec video and 128 kb/sec audio so around 830 kb/sec. The file will be smaller.
If you pick the Apple TV export preset it is at about 1500 kb/sec so the result will be 50% bigger.
Depending on the source codec using a lot higher H264 bitrates may not make it look better anyway (you cannot create data) , so try the basic iPod setting - benefit - reasonably small - a 45 minute TV show for me is about 270MB yet looks good on a TV set via iPod, and you will have iPod compatibility as well.
Use MPEG Streamclip 1.9b3 version.

How do I decrease the file size of my After Effects video without losing the quality?

I made a video that was 7 minutes and 11 seconds long for my brothers wedding. The quality is really good but the file size is 1.52 GB and I would rather have that be in the megabytes so that I can send it to family members. It does not have to be so low that I can send it in an email but just not so big to where I can't burn it to a disc or place on a flash drive. I realize that I have not provided much information but I don't know what you will need to help me with this problem. If you would please tell me what information you need below then I will happily provide it for you.

Premiere Elements 11 file sizes

Premiere Elements 11 file sizes?
I recorded small 170MB and larger 570MB videos with audio using HyperCam 3.
Both load and play back in Windows Media Player (ver 12.0.7601.18150) without a problem.
I can load and play back the small files in Premiere Elements 11 without a problem.
But, when I load the larger file into Premiere Elements 11, only the sound track loads and plays.
No video track and the preview screen is a solid black box on my monitor.
Is there a file size restriction in using Premiere Elements 11?

By the time I downloaded and looked at your sample video, I see that you and nealeh have worked out a workaround, that is, converting your Microsoft Video 1 (CRAM).avi (1920 x 1080 @ 10 frames per second) to H.264.mp4 (1920 x 1080 @ 30 frames per second.
I was able to convert your sample video into H.264.mp4 (1920 x 1080 @ 30 frames per second using the free HandBrake program). All 11 minutes 52 seconds of the H.264.mp4 imported into Premiere Elements 11 without issue.
In the case of these converters, we are dealing with changes in at least video compression, file extension, and frame rate.
However
The tests brought up some interesting questions
1. When I ran your file through the gspot utility, the video codec was shown as Microsoft Video 1 (CRAM), but it listed Codec NOT installed.
2. In spite of the Codec NOT installed, I was able to play back your video in Windows Media Player and VLC Player.
3. Your Microsoft Video 1 (CRAM).avi imported with the complete duration of the file, but only audio, no video.
Further
4. When I ran my own Premiere Elements 11 created Microsoft Video 1 (CRAM).avi (30 frames per second, 11 min duration) through gspot, the video codec was shown as Microsoft Video 1 (CRAM), but it listed Codec NOT installed - same as yours.
5. Yet, my file imported into Premiere Elements 11 completely (video and audio).
6. I need to run a Microsoft Video 1 (CRAM).avi 10 frames per second, 11 min duration) to see if I get the same results as in 5.
When you record your video, do you have the option of changing the frame rate from 10 to 30 frames per second?
So, some of the questions that the remain for me
a. Why is my Premiere Elements 11 created Microsoft Video 1 (CRAM) appearing to be different from the Microsoft Video 1 (CRAM) that you use in your file?
b. Why is gspot telling me that the Microsoft Video 1 (CRAM) codec is not installed when I can use it in Premiere Elements 11 for the import and export of my own file?

ERROR importing AVCHD H.264 files on Windows

I have a problem that is preventing my students from moving forward with their work, and I am STUMPED as to what the issue is. Computers are all the same, Windows 7, 64bit Enterprise (Octo-Core Xeon 3ghz with 11GB of RAM). CC is installed with the the CCP Enterprise installation tool, and all apps have been updated via Adobe Updater to the latest revs, Premiere happens to be at 7.2.1(4).
All our digital cameras are Sony’s that shoot to AVCHD H.264 (I have provided a profile of a sample clip, below).
Video ingests into Prelude when the material is simply copied from the SD card to a local drive. However, when we attempt to send the video to Premiere Pro, the files all come up as OFFLINE (question mark icon). When I attempt to import the file manually, the following error is received "The file has an unsupported compression type.".
The next thought was to attempt to transcode the files to another codec (in this case, I used DNxHD as a test). When the files are sent from Prelude to Media Encoder, the same error occurs (Media Coder is unable to determine the compression type) and all transcodes fail. As an aside, After Effects is also unable to import the same media.
This has happened now on numerous computers, and (obviously?) seems to be related to a lack of installation or support of AVCHD/H.264 compression. What’s odd is that students have been using these cameras and compression types all year, so I am guessing a recent update killed support?
If anyone could offer any help/ideas/support/thoughts it would be GREATLY appreciated!
Thanks!

OK, I am flummoxed. I just worked with out IT guy for about 40 minutes trying to narrow down the issue. So far, NOTHING is reliably reproducing the issue. Here's what we've done so far...
1) Deleted all local user profiles except for admins, then deleted all registry keys relating to those profiles.
2) Students log in and a new profile is created, we then opened up their existing Premiere Pro project files. Problem still presents itself.
3) We create a new Premiere Pro project and attempt to import the material from the copy on the local hard drive (not the original SD card). Problem still presents itself.
4) We open a new Prelude project to import footage again directly from the SD card again, and Prelude is able to "see" the footage that is copied over to a new folder on the local hard drive (no transcoding). This is promising, so we open up Premiere Pro, and only 4 of 15 files are viewable (the others present the same error that no supported compression type is available).
5) I try reimporting some of the 11 files that don't work again through Prelude, and this time they work! I note that the video files that DO WORK were imported into a folder that DOES NOT have a space in its name. However, the folder that DOES NOT work DOES have a space in its name. I think I am onto something. So...
6) I have the same student log into a DIFFERENT COMPUTER and we import the SAME FILES into Prelude and create a sub-folder that HAS A SPACE IN IT like the other computer has (we are trying to replicate the problem). And... It works just fine. We can see the files in a folder with a space in its name. So...
7) At this point, I am attempting to reinstall the Adobe CC suite on the affected computer, and we will see if that solves the problem. Fingers crossed...

File sizes saved in MAC much bigger than saved in PC-is there a fix?

HI everyone -
I searched and couldn't find an answer for this specific issue so Im hoping I can be pointed in the right direction. Appreciate any help with this issue.
About a month ago got a MAC (I upgraded everything and have 12GB RAM so I know it's not the machine). Prior to this was using PC Win 7 ultimate - same deal-AMD Phenom quad core, 8GB RAM (I'm only telling you this because it said to say this when you post-I'm not trying to be a dork)
Here's my issue - I'm using CS5 on both the MAC and the PC. I do layered TIFF files that I eventually save to JPEG. I noticed that when Im saving these files from TiFF to JPEG on the MAC they are bigger than when I do the very same thing-same settings, etc in the PC.
Here is what Im doing - I have my TIFF file open, I flatten it, File - Save As - JPEG. I took the same exact file and put it on both machines to see exactly what the difference was and here is what I got when I chose quality of 8 under Image Options:
On the MAC the file size is 264.2K
On the PC the file size is 137.0K
WHY?? How can I make it stop? I have to have these files under a certain amount when I upload them and my MAC is my main computer so I have to find a fix.
Can anyone possibly help with this?
Thank you in advance!
Susan
edited to add that I am using MAC OSX 10.6.7.

Thank you Marian!~ When I unchecked the boxes under prefs - file handling that say ICON and WINDOWS THUMBNAIL, it changed it all for me in a good way
Now my file sizes are the opposite!
MAC (quality at 8) = 255KB
PC (quality at 8) = 261KB
You're awesome- thank you SOOO much. That was driving me crazy!

Output file size restrictions - HD Video for YouTube

For over a year YouTube has removed restrictions on file sizes for individuals that want to do so. The preset output in Premier Elements 11 for "Online - HD Video for YouTube 1920X1080" will not allow a video longer than 15 minutes. I need to remove this restriction and be able to produce files to upload to YouTube without file size restrictions. How can I do this?

You cannot. And, Premiere Elements 12 has the same YouTube limitations as 11.
You need to export your Timeline to a file saved to the computer hard drive, and then upload that file to YouTube at the YouTube web site.
At YouTube, you would need to explore the opportunities that it offers in the way of "extended times". It may require special accounts.
Without further details of your Premiere Elements project preset and the properties of your source media, I would generalize and suggest that you look at the follow choices for creating this file for upload to YouTube at the YouTube web site...
Publish+Share
Computer
AVCHD
with Presets =
MP4 - H.264 1920 x 1080p30
or
YouTube Widescreen HD (changing the settings under the Advanced Button/Video Tab of the preset)
Please review. If you have any further questions on this, please do not hesitate to ask.
Thanks.

Huge, Huge, Huge file size

Hello,
I have a short movie from about 5 minutes, but when it's rendered the file size is 799 MB. I know this isn't normal, but can someone tell me what I'm doing wrong? I use save the file as a quicktime movie, with audio (I use the Composition > Add to render que thing).
Thanks in Advance,
Steven Raaijmakers

That file size isn't that abnormal. I render out 10 second animations that are over 2 GB in size relatively regularly.
"Quicktime" is only a container, just like AVI is only a container. There are tons of compression possibilities within it. What codec you use and the codec's settings all determine how large your final video file is.
Generally speaking, the best practice is to export a lossless file from AE (which is going to be large) and use a different program to compress it.
My friend Dave LaRonde from CreativeCOW.net explains why:
Don't use AE to compress files for final delivery. The various compressors are there only to make quick 'n dirty files showing a project's progress to producers, clients, the kids, etc. AE is incapable of doing multipass encoding, a crucial feature that greatly improves the image quality of H.264 and MPEG-type files in particular.
Render a high-quality file from AE, and use a different application to do the compression. Popular ones are Adobe Media Encoder, Sorenson Squeeze and Apple's Compressor, which comes bundled with Final Cut Suite. Even compressing in Quicktime Pro is better than compressing in AE.
Making good-looking compressed files is almost as much an art as it is a science. It is NOT straightforward at all.
There is even a whole forum at CreativeCOW.net dedicated to compression techniques.

"Convert Selection for iPod" Command Increases File Size?

Hello!
I'm trying to convert a file that has the following characteristics (as reported in Quicktime Pro):
Format: H.264 Decoder, 496 x 208, Millions, AAC, Stereo (L R), 44.100 kHz
FPS: 25
Data Size: 572.20 MB
Data Rate: 659.18 kbits/sec
Normal Size: 496 x 208
I know the dimensions are strange, but it's because this is just a test I'm running on a workflow using Hand Brake to bring content back from a DVD (my content).
Now, when I drop just the original file into iTunes and then try to put it on an iPod, it says it can't be played. So I use the handy new option in the Advanced menu, "Convert Selection for iPod." This yields a new file with the following characteristics:
Format: AAC, Stereo (L R), 44.100 kHz, H.264 Decoder, 640 x 268, Millions
FPS: 25
Data Size: 1.36GB
Data Rate: 1609.01 kbits/sec
Normal Size: 640 x 268
How is it that the data rate and file size have increased so much? It now plays on an iPod, but why? I was under the impression that usually the problem with getting video to play on an iPod was a data rate that is too high. So it seems strange to me that the second file works and the first doesn't.
Finally, what is the difference between a file with the extension .mov and the extension .m4v? The original file has .mov and the converted ends up with .m4v. But they have the same characteristics in terms of codec. So what's the difference?
Thanks for any help and info!

I think I was able to resolve this myself after some trial and error. It looks like it is all in the name of the file. I've gotten some files to transfer after going into the Get Info section and updating the name (usually shorten the name or take out non-letter/number/# characters and then get the filename on disk to match.

Output Compression Increasing, not Reducing File Size

Hi guys
I have Pr CC2014 on a Win7 PC, with a Nvidia Quadro FX3800 and I'm having nothing but problems lately. Apart from CUDA doesn't open properly, my exports are getting worse and worse. The quality is much degraded from the preview in edit. Now compression seems to be working in reverse. Today a simple 9 minute interview (a mixture of hdv and hdtv clips, with just a couple of dip to black transitions and a short aep import, output to h.264, with a YouTube 720/ 25fpsHD preset), ended with a file size of 1.7gb, which is two or three times as big as all the material in the sequence! Up until CC2014, it was around 200/ 300mb! I even tried exporting to MPEG 2. Although a lower file size, it is still double what I have been getting previously and the YouTube quality isn't good enough.
My sequence settings are:
HDV 25 FPS,
Frame size, 1440x1080,
Pixel aspect, HD Anamorphic 1080 (1.333),
Fields, upper first,
Codec MPEG I-Frame
Composite in liner color
My output preset is h.264 but keeps defaulting to match source high bit r ate,
profile, high,
Level 4.1
VBR, 1 pass
Multiplexer settings are MP4, standard
I probably can't see the wood from the trees, but any help would be much appreciated.
Graham

Thanks. I haven't tried AME, but I'll run it through as a test and see what happens.
