Smallest file size for talking head, MPEG1?

Hey friends, back again, still using PRE8.
I have to encode a talking head into a watchable quality for a podcast. Prefer between 320x240 and 640x480, prefer the later. I inadvertently tried some combination of VCD 352x240 and got an amazingly small file size that looked tollerable....and no audio (that part not so good). I cannot figure out what I did, though I probably started out with VCD setting and modified one of the video or audio characteristics, multiplexer (who knows).
The file output was a m1v and was under 99MB for an hour and a half. Other formats have all been a gig or so.
Sure, no audio is a lot smallar (don't think I disabled audio, smarter than THAT) but I can't seem to get any kind of m1v file again, pref with the audio.
Any thoughts?
While this will be viewed on a PC, we don't have a lot of bandwidth or storage space available currently. Fortunately, only graphics are at the start and end and don't have to be sharp, there is no whiteboard or other hard to encode detail.
Thanks a lot
Don

Yup Steve, for the web.
I have tried everything twice by now, and can't seem to get it to produce a m1v file again............
You know what? Think I just figured it out.
I did a search of files with my working file name after creating an mpg (which is all I seem to be able to get, even with VCD settings. Anyway, I picked up the m1v file from who knows what directory. It MAY be that the m1v file is created by PRE8 in the process of creating the mpg, and left in one of its working directories, for re-use later. PRE8 probably never intended that to be used, because it's a video-only WORKING file...Make sense?
It's hard to believe, a working video file for a 800meg mpg is 99meg. and looks pretty good. Add audio and it balloons to 800 meg? Makes no sense.
The best I can do is around 500 meg for a mpeg, and in generating a mp4, PRE8 does not change the predicted file size when you change the frame rate and hardly at all with the resolution. In mpeg 1 there is a big difference, as expected.
Unfortunately cant use flash either.
It would be nice if there was a chart someplace that gave you file size comparrisons for the various encoders and options!

When bouncing- what's best method for smallest file size/highest quality?

I am in the process of embedding 3 mp3's into a PDF to submit as a portfolio. The PDF also has text, and two scores included, and with the 3 embedded mp3's it can't be more than 10mb.
So my question is: When bouncing a project out of Logic, what is the best method for getting the smallest file size, but retaining the best audio quality? And once it's out of Logic and it is an mp3 or other type of audio file, is there a best format for compressing it further, and still maintaining the relative quality?
I bounced out the three projects into wav's. Now I am using Switch for Mac to compress them down to smaller Mp3's. I basically need them to be about 3 mb each. Two of the recordings sound OK at that size, but they are just MIDI(one project is piano and string quartet, the other is just piano- all software instruments. The recording that combines MIDI and Audio and has more tracks (three audio tracks and 10 Midi/software instrument tracks)and sounds completely horrible if I get it under 5 mb as an mp3. The problem is that I need all three to equal around 9mb, but still sound good enough to submit as a portfolio for consideration into a Master's program.
If anyone can help I would really appreciate it. Please be detailed in your response, because I am new to logic and I really need the step by step.
Thank you...

The highest bitrate that falls within your limits. You'll have to calculate how big your MP3's can be, then choose the bitrate that keeps the size within your limit. The formula is simple: bitrate is the number of kilobits per second, so a 46 second stereo file at 96 kbps would be 96 x 46 = 4416 kbits / 8* = 552 kBytes or 0.552 MB. (*8 bits = 1 Byte)
So if you know the length of your tracks you can calculate what bitrate you need to keep it within 10 MB total.
I consider 128 kbps the lowest bearable bitrate for popsongs and other modern drumkit based music. Deterioration of sound quality is often directly related to the quality of the initial mix and the type of instruments used in it. Piano(-like) tones tend to sound watery pretty quickly at lower bitrates, as do crash and ride cymbals. But don't take my word for it, try it out.
And once it's out of Logic and it is an mp3 or other type of audio file, is there a best format for compressing it further, and still maintaining the relative quality?
You can only ZIP the whole thing after that, but that is just for transport. You'll have to unzip it again to use it. And no, you cannot compress an MP3 any further and still play it.
I bounced out the three projects into wav's. Now I am using Switch for Mac to compress them down to smaller Mp3's.
That is silly, you could have done that in Logic, which has one of the best MP3 encoders built in. And how good encoders are will especially come out at bitrates around or below 128, which you might be looking at.
I basically need them to be about 3 mb each.
So, one more scrap of info we need here: how long are those three pieces, exactly? I'll calculate the bitrate for you - but please bounce 'm directly out of Logic as MP3's. They will very probably sound better than your WAV-conversions made with Switch.

Length of the piece? And does the .Wav bounce you have sound OK?

Converting to smallest file size

Trying to convert QT 3 minute movie to the smallest files size(so it can be emailed) and not sure what the best setting would be....

Sure, you will get a small file size, but how watchable will the video become?
We are talking about a 3 minute video, which can easily become less then 10MB, using the 300 Kbps H.264 preset, with a frame size of 320x240 or 320x180 anamorhpic. That should be an acceptable file size for e-mail.
I just did a test encode of a 3 minute video, using the 300 Kbps H.264 preset (80 kbps, 32 kHz AAC audio), and the file size became 6,7MB. Great quality for e-mail size video!

How can I auto export a PDF File using the "Smallest File Size" preset and set the Exported File Name based on information from an Imported PDF?

Greetings all,
I am trying to create a script to automate a PDF export process for my company for inDesign. I’m fairly new to inDesign itself and have no previous experience with javascript, although I did take C++ in high school and have found it helpful in putting this code together.
We have an inDesign template file and then use the Multi-page PDF importer script to import PDF files. We then have to export two version of each file that we import, then delete the imported file and all of the pages to reset the template. This has to be done for nearly 1000 pdf files each month and is quite tedious. I’m working on automating the process as much as possible. I’ve managed to piece together code that will cleanup the file much quicker and am now trying to automate the PDF exports themselves.
The files are sent to us as “TRUGLY#####_Client” and need to be exported as “POP#####_Client_Date-Range_North/South.pdf”
For example, TRUGLY12345_Client needs to be exported as POP12345_Client_Mar01-Mar31_North and POP12345_Client_Mar01-Mar31_South.
There are two templates built into the template file for the north and south file that are toggled easily via layer visibility switches. I need to get a code that can ideally read the #s from the imported Trugly file as well as the Client and input those into variables to use when exporting. The date range is found in the same place in the top right of each pdf file. I am not sure if this can be read somehow or if it will have to be input manually. I can put North or South into the file name based on which template layer is visible.
I am not sure how to go about doing this. I did find the following code for exporting to PDF with preset but it requires me to select a preset and then type the full file name. How can I set it to automatically use the “Smallest File Size” preset without prompting me to choose and then automatically input some or preferably all of the file name automatically? (If the entire filename is possible then I don’t even want a prompt to appear so it will be fully automated!)
PDF Export Code (Originally from here: Simple PDF Export with Preset selection | IndiSnip [InDesign® Snippets]):
var myPresets = app.pdfExportPresets.everyItem().name;
myPresets.unshift("- Select Preset -");
var myWin = new Window('dialog', 'PDF Export Presets');
myWin.orientation = 'row';
with(myWin){
    myWin.sText = add('statictext', undefined, 'Select PDF Export preset:');
    myWin.myPDFExport = add('dropdownlist',undefined,undefined,{items:myPresets});
    myWin.myPDFExport.selection = 0;
    myWin.btnOK = add('button', undefined, 'OK');
myWin.center();
var myWindow = myWin.show();
if(myWindow == true && myWin.myPDFExport.selection.index != 0){
    var myPreset = app.pdfExportPresets.item(String(myWin.myPDFExport.selection));
    myFile = File(File.saveDialog("Save file with preset: " + myPreset.name,"PDF files: *.pdf"));
    if(myFile != null){
        app.activeDocument.exportFile(ExportFormat.PDF_TYPE, myFile, false, myPreset);
    }else{
        alert("No File selected");
}else{
    alert("No PDF Preset selected");
So far my code does the following:
1) Runs the Multi-Page PDF Import Script
2) Runs PDF Export Script Above
3) Toggles the Template
4) Runs #2 Again
5) Deletes the imported PDF and all pages and toggles template again.
It’s close and much better than the original process which was almost 100% manual but I’d like to remove the Preset prompt from the PDF script and have it automatically select the “Smallest File Size” preset. and then if there’s a way to have it auto-fill in the file name so no user input is required at all other than selecting each file to import. (If there’s a way to setup a batch action for the multi-import script that would be even better!)
Thanks in advance and if there’s anything else I can provide that would help please let me know! Even a nudge in the right direction will be a big help!

If you hold down the option key, it will typically show the location. Or you can often hit option-return on the file and it will reveal the file in the Finder, instead of opening it.
Final option is to open it, and just option-click the filename in the toolbar of Preview and it should show you the location.
It's probably an attachment to an email you've received. If you have Mail set to cache emails and their attachments it'll be stashed in a subdirectory of ~/Library/Mail. Which is fine.

How to create a smallest file size pdf from indesign CS4 document

How to create a smallest file size pdf (suitable for upload to a website) from indesign CS4 document which contains multiple illustrator CS4 illustrations.
I have chosen the "smallest file size option" but the pdf file is over 30MB, can anyone help please.
Thank you

One trick is to
Set the placed graphics to have a transparency of 99.9% (you can do this with Find/Change and select Objects)
This is enough to force the graphics throught the Transparency Flattener
Next set the Transparency Blend Space to RGB (Edit>Transparency Blend Space)
Next set a custom Transparency Flattner Preset Edit>Transparency Flattner
Next
Use File>Export and choose
Smallest file size
PDF Compatibility Acrobat 4 (PDF 1.3)
In Advanced Section - go to transparency and selec the new Flattener Preset you created.
*this will convert your vectors to raster, but it should reduce your file size

Export to PDF (smallest file size) is giving me a very large file

Hi all,
I got 2 document with around 100 pages (same size), with a picture or two in each page.
I've been using the Export to PDF (smallest file size) and export it.
first file became 5MB, which is fine
second file became 30MB, this is much too much.
I have used the exact same setting for both files and have no idea why the big difference between them.
The only difference between them is that first file contains CMYK photos, and second one - RGB.
Can this be the difference?
Any suggestions?
thanks,
shlomit

That's certainly part of the difference. Additional font information if one of the documents uses more fonts or additional glyphs could be some of it, too. Swatches and styles might also be a factor. Vectors don't compress like bitmaps, either.
Have you opened the optimizer and done a space usage audit to see what is taking up all the space? Did you do a Save AS before export?

Reducing AI file sizes for PDF distribution

Greetings all,
Using CS2 Illustrator, I have a file that is approximately 14.5M large. It's completely black and white, with a b/w photo. I was thinking that when I saved it as a pdf file, the size of the pdf document would be considerably smaller so people could send it by email. It came down to 1.9, but I'd like to get it smaller than that. I'm guessing I have to reduce the size of the embedded photo?
I also have a version of the file with a color photo. It's AI size is 34.1M, it's converted pdf file size is 32.5. I'm desparate for a method that will get these two documents down below 1M size so that members of my Barbershop Chorus can send the pdf files out announcing our upcoming show.
Any help GREATLY appreciated.
Thanks,
Bond

When you save the PDF, Illustrator will downsample images according to the settings you chose. Downsampling the source images won't help for file size. Usually the biggest source of bloat is leaving "Preserve Illustrator Editing Capabilities" on. This adds the entire Illustrator file to the PDF.
I suggest you start with Smallest File Size and adjust the downsample options under Compression. Reduce image resolution if sizes are still too big or increase resolution or image quality if sizes can be increased and quality is unacceptable.

When using the Save Layer Comps to PDF Script, can you change the PDF settings. I need both Smallest File Size and Press Quality?

When using the Save Layer Comps to PDF Script, can you change the PDF settings. I need both Smallest File Size and Press Quality? Thanks in advance to the group for assisting with this matter.

No, there isn't. The way you're using the file is not recommended. You
should use a review tracker to avoid getting in the way of one another.

What is an idea of maximum file size for a film in Captivate?

Hi there,
I'm creating an elearning course in Captivate 7, and it is being published as HTML5. This means the films I've imported are being converted to MP4s, and they are around 10-20mb in size once they've converted. They seem very slow to load on some computers - do you think the file size is too big? Or could it be another issue? Does anyone have a recommendation for maximum file size for films? They are 572 x 322px and around 1-2 mins in length.
Thanks in advance

Probably better guidelines that dictates 'size' of a vi are:
typically no more than 1 video screen in size
is it legible
and is it's function and operation clear.
I have seen examples of '1 vi does it all' that were many screens wide and tall, totally a flustercuck, and nearly 1 MB in size.
Globals and local variables (except for LV2 style) are typcially shunned for they can create a host of problems (race conditions, indeterminant data).
Use connector pane to wire controls and indicators to. Then use wires between vi's to transfer data. I tend to use clusters to hold shared data.

How do I find a file size for a project in its entirety ???, How do I find a file size for a project in its entirety ???

How do I find a file size for a aperture project in its entirety ????

You can't. The Aperture library is a combination of database and flat files, a project can be split among multiple files in combination with other projects. The size of any of those files (or a sum of the files) would have no meaning concerning the size of a project.
BTW typing in a large bold font like you did is seen by many in then on-line community as a sign of shouting and is considered bad form. I'm sure you didn't mean to shout at us here as we are all just users here freely giving of our time to try and help folk like yourself so please in the future use the standard font.

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

Maximum file size for importing into Premiere Pro CS6

Hi,
I'm considering recording raw video, no compression at 720p, 30 fps for 20-30 min. This woudl result in a file that is close to 80 Gbytes. I'm wondering what the maximum file size for importing into premiere Pro is and if I need to split this file up into smaller pieces. Any recommendations on how I may deal with uncompressed raw video that is pretty long in length?
Thanks,
Serena

There is bound to be some limit somewhere in the program, but you should be well below that. The biggest issue might be whether your computer is up to the task of handling it. If you will post your computer specs., someone will give you comments on that aspect.
Good luck,
Hunt

Session "Circular Kernel Context Logger" failed to start with the following error: 0xC0000035
As suggested above I assume this is a microsoft issue? It has been discussed here and other forums for quite some time. I never have seen a fix? I wish when we received errors of this nature microsoft would tell us what they were. How is this related to superfetch? What is superfetch? Why would superfetch have changed?
BY THE WAY.... Superfetch is on(started) is on automatic and logs on as local system. So this is not the cause of my issue. Also what is readyboot? Does the average computer really know what these programs/services or unique microsoft words/terms are?
