24p Pulldown Conversion Quadrupling File Size?

I found this useful thread below describing an easy foolproof method for converting to true 24p using Compressor 3:
http://www.dvxuser.com/V6/showthread.php?t=98411
But alas, every clip that I convert becomes five times larger in size.
218.7 MB after compressor becomes 1.2 GB
71.8 MB becomes a new file of 391.2 MB
215 MB becomes 1.17 GB
Obviously there is more of a decompression going on here. Any Clues?

You're failing to account for how the data rate - how much space one second of video takes up - differs between the HDV codec (what FCP digitizes) and the ProRes422 HQ codec.
The data rate of your HDV clips are so much lower because it uses interframe compression. In plain english, even though there are 30 frames of video recorded to tape, not all 30 frames are complete, standalone images - they rely one other images to complete them. This makes HDV very efficient when it comes to hard drive space, but a total nightmare when it comes to post and editing.
ProRes422 HQ does not make use of interframe compression, so each second, despite containing fewer frames, does contain complete frames. ProResHQ's data rate is variable (depending on the frame size and source picture) but it is, as you've found, beefier than HDV. Much beefier.

QT X conversion increases file size

Now this maybe something that all versions of QT did but I never used QT before for converting movies as it took so **** long,I always used Visualhub.
I thought I'd give QT X a try and the speed seems to have improved but it increased the file size to almost double using the iphone optimization.
Space on an iphone/ipod is at a premium and they go and engineer a conversion that doubles the file size.
What is the point of that?
If I do the same conversion using VisualHub the file size stays the same.
Surely apple can do better than that

Here is the reply that I could swear I saw in this thread yesterday. It seems to have disappeared somehow...

LZW compression does not work on 16 bit TIFFs, it was never intended for this format. The TIFF format started out as 8 bit only together with LZW.
Basically all image compression exploits sequences of equal pixels. The chances of two pixels being equal goes to zero when increasing the resolution. After that you only add the overhead of the bookkeeping tables of the compression itself.

HD down conversion/HD file sizes

I just have a few quick questions on working with HD, as this is my first time.
First, if I am shooting in HD, but my final output will be SD, where does the down-conversion happen? Can I simply capture in SD, even though the footage is HD, or do I have to capture and edit in HD, and then down convert when I export the project to Compressor?
Also, one quick question about HD file sizes- I have found that SD DV footage file sizes are roughly 4.5 minutes per GB, using the DVNTSC capture codec. I expected HD files to be much larger, but after capturing roughly 4 minutes of video, the files were less than 1 GB. The files were definitely 1920x1080, and I captured using the Sony HDV codec 1080i60. Could I possibly be doing something wrong or is that how it is? I was sure HD files would be huge.

You need to be specific about what format of HD you are talking about here. There are MANY flavors. Uncompressed 10-bit, uncompressed 8-bit...both in 1080 and 720p options, then there is DVCPRO HD, XDCAM, HDV...but going by your last post I assume you mean HDV, the lowest form of HD.
HDV has about the same file sizes as DV (yet 3 times the area...thus it is HIGHLY compressed)..about 13GB per hour. DVCPRO HD 720p24 is about 24GB per hour, 1080p around 54GB per hour. Uncompressed...lots more. But HDV is about the same as DV...file size wise.
Your final output will be what format of SD. Again...there are many. Digibeta, betaSP, DV. If your final output will be DV, then it would be advisable to capture the footage as DV. Other wise you will edit in HD and need to downconvert when you are done. Either a capture card (matrox MXO is good for HDV) or by dropping the footage into a DV timeline and rendering or via Compressor. But it would be easier to edit DV to begin with if you are outputting DV.

60p to 24p Pulldown Conversion - Best Settings?

Our studio recently purchased a new camera for some run-and-gun shooting. Unfortunately, it does not support 24p natively, only 60p & 60i. It does, however, support shutter speeds from 1/2 all the way to 1/4000. What advice can you give regarding pulldown conversion into a 24p project, both for camera settings and FCPX?
Please note that I'm looking for 1:1 speed, NOT slow-mo.

Shane, I understand the difference in motion. And as I said, it was not my intention to capture at the frame rate that I did. With regards to the slight stutteryness, I'm comparing one of these problem clips to an actual 24pN clip from an earlier part of the shoot. I put both in the 23.97 timeline, but the one captured at 60p feels like it should still run slightly smoother or with a little bit more motion blur maybe. I think I'm simply looking for the best way to cheat that "look" back into the footage.
Your post below is right. Cinema Tools is not a good option for that as this doesn't really have much to do with 2:3 3:2 pulldown type operations and it won't let me conform the footage anyway.

For the Batch Sequence that "asks" --
Something to try.
Open the Batch Sequence dialog.
Select the appropriate Batch Sequence.
Click the Edit button.
In the Edit Batch Sequence - <name of sequence> dialog, use item number 3's drop-down menu.
From the menu, select 'Same folder as originals'.
"OK" out of the dialog.
Give the Batch Sequence a test run.
Output ought to be to the same folder as that of the selected & processed files.
Be well...

File Size Conversion Problem

I recently began to see large pdf files being generated intermittently, even at relatively low dpi.
So to test, I took two jpg photos and converted them to pdf using Acrobat 9.2 Pro at 72, 144, 300 and 600 dpi. The resulting pdf file sizes are 106KB, 1920KB, 1195KB and 361KB respectively. I have never experienced this problem before, so I un-installed and re-installed the program, but got the same results. Any thoughts? Thanks

Any details on how you did the conversion? Are they B&W, grayscale, 256 colors, or a 24-bit color graphic? What is the size?
Of course you may also see compression aspects coming in. How you select the DPI can make a difference. In one package I have, when I adjust the DPI, the size changes and the resultant file size when printed to PDF remains about the same. The size combinations you give seem real strange, but it may be a combination of DPI, size of graphic, and downsampling by Acrobat. If you do not want the latter, then you should probably use a Press or Print setting if printing to retain the max resolution of what you are printing.
Note I feel into a discussion of printing, but you may have done something differently. How you set the DPI could be an issue. If these were graphics that you imported into a PDF, then give the graphic size, not just the DPI. We have to be able to replicate your problem to help in many cases. We at least need to know the steps you used as the answer may be starring us all in the face when the steps are provided.

SAP Data File size considerably reduced after Unicode Conversion

Hello Experts
I have just performed a CUUC (Upgrade along with unicode conversion) from R/3 4.7 to ECC 6.0 EHP5. The data size that i earlier had was close to 463 GB (MSSQL MDF, LDF Files), after the data export to be converted to unicode the size was 45 GB (10% of actual data size, i feel this is normal after heterogeneous system copy), but after the import again the DATA file size is only 247 GB, is this normal ? or have i lost some data ? For ex, I tried checking tables like MSEG and the number of entries have reduced from 15,678,790 to 15,290,545.
Could you kindly let me know if there is a way to check from Basis perspective if i have not lost any data ? I have followed all the procedures as per SAP Standards.
Waiting for your quick reply.
Best Regards
Pritish

Hi Nicholas
Data is compressed during the new R3load procedure is understood, but why number of table entries have reduced is something which is still a question to me (in some cases increased as well) ? For example
                             Source          Target
STPO                  415,725          412,150
STKO                 126,710          126,141
PLAF                 74,671                   78,336
MDKP                 193,487          192,747
MDPB                 55,329                   63,557
Any suggestions or ideas ?

PDF reduce file size filters and CMYK to RGB conversion

This doesn't seem to be on-topic to this forum, but I'm hoping someone here has the expertise to answer my question. We have some scripts which take a series of press-quality pdfs and use the "reduce file size" filter to prepare them for viewing on the web. We run these scripts on a 10.4 machine, and the filter works very well, reliably reducing file sizes of all sorts of pages.
When we tried to upgrade the machine, we discovered that the quartz filtering has changed in 10.5 and 10.6. While it's usually an improvement, getting maybe 5-10% better compression ratios, it has become unreliable in that about 5% of my files fail spectacularly -- they blow up to 3, 4, 5, 6 times the original size.
The other thing that happens is that the 10.5/10.6 filters munge the colors up. I found the solution to this -- in the ColorSynchUtility, make a duplicate of the Reduce File Size filter, and add a Color Management Component called Convert To Profile. This allows me to set a filter that converts the CMYK content to RGB. The problem is that there are about 40 choices of profiles, and it's not at all clear what I should use. Many of them have printer manufacturer's names in them, some say "Adobe", others have cryptic codes (probably referring to various RFCs and schemes). I've tried a couple of the ones that don't look like they are for printers, basically chosen at random. They all produce files of slightly different sizes for the reductions that go well, but on the files that blow up, some filters are better than others. (For example, I have a 5MB page which reduces to 1.4MB with the 10.4 filter, but blows up to 27MB with the "sRGB IE61966-2.1" profile, but only 12MB with the "Adobe RGB" profile.)
So I have 2 questions:
1) Is there any way to configure a 10.5/10.6 custom profile so that it behaves as reliably as the 10.4 "stock" PDF Reduce File Size works? It doesn't have to be the most wonderful compression algorithm out there, just so that it never or rarely has a file blow up in size.
2) For converting press documents to pdfs that are going to go on the web, what is a good "Convert to profile" to use of the 40-some choices on the pull-down menu?

Cathy,
You have posted your question in a forum dedicated to the Final Cut Studio application Color. It is a very specialized program to grade (adjust) the color in video/film images. We know nothing regarding PDFs.
Have you tried posting this on an Adobe support site?
Good luck,

Large file sizes in Captivate 4 to 5 conversion

I just upgraded from Captivate 4 to Captivate 5. When I open projects created in Captivate 4 and then resave them as Captivate 5 files (.cptx) the file sizes increase dramatically (e.g., 26,000 kb to 184,000 kb). I have deleted all unused objects and resaved, but the file sizes are still very large. Should I do something other than just opening them in Captivate 5?

Hi,
We are aware of this issue and I assure you that we are already working on a fix for this.
Will it be possible to share your Cp4 file with me? I would appreciate if you can mail it to me at 'thejas at adobe dot com'
Thanks,
Thejas

Ntsc to pal conversions with small file sizes

I'm trying to convert a file from NTSC to PAL, which I have done successfully in the past. However, the file needs to be under 200MB (the video is 3.40) and I can not seem to get it any lower than 346 MB using the dv-pal setting and everything as low as possible and the sound set to mono. Any suggestions?
Thanks,
Christy

DV PAL is a set data rate - 3.56 MB/s when run at 25 fps.
If you want a smaller file size you have two choices -
1. convert the file to another codec that allows for smaller frame sizes, slower frame rates and increased intra and inter frame compression.
2. If it must be DV/PAL, cut the length of the video to reach your 200mb limit.
Of course there is the third choice of simply giving them the larger file because that's what an un-compromised DV/PAL version of the file will be.

RAW Conversion to JPG file size question

I'm fairly new to Lightroom and have noticed when I convert from RAW to JPG my approx. 8MB RAW files become approximately 2-3MB JPG files. I have the program set to convert to JPG at the highest possible quality. I've had clients ask about the file size and would like to be able to explain this to them in simple terms but I first need to understand why this is the case myself! When I used a different processing program the converted files were only slightly smaller than the originals. Please explain!
Thanks!

It depends on the quality settings you use. JPEG files have I think 12 quality settings, with 12 being pretty big, and 8-10 being reasonable compromises.
This is lossy compression, so data is thrown away. The quality setting determines how much info is thrown away.
Only thing you can really do is export at a few quality settings and compare them, to see if YOU can see the difference.
For me, I don't really care about minimizing file size so I always choose highest quality.

File sizes after transfer

I got a new computer and used the instructions for transferring songs to your new PC using your iPod and iTunes 6. It all went pretty well except when I got done there was nothing in my library except my purchased music. The instructions had stated to drag the “my music” folder out to the desktop and copy the iTunes folder into it, which I did.
When the songs did not show up in my library I started over and on the second try they showed up in the library. But now I have a folder on my desktop, “my music”. When I double click this folder it opens the “my music” folder which has 2 folders in it, iTunes and sample music.When I double click the iTunes folder it brings up more folders, iTunes music library (2.79 gb), iTunes library (2.49 gb), my music (5.52 gb), iTunes music (5.58 gb) and album artwork (38.9 mb). So it appears that I have gotten the songs in there twice somehow.
My question is, can I safely delete the “my music” folder that is on the desktop? In iTunes the direction the songs take is as follows: C:\Documents and Settings\Sandy\Desktop\My Music\iTunes\iTunes Music. I don’t think desktop is usually part of the path so I probably did something when I did the transfer. Sorry for the long post, and I hope it makes sense, but if I don’t need to take up all that space on the hard drive I would like to delete something but right now everything is working and I hate to “fix it if it aint broke”.

Depends on what your cam's setting were when you recorded and how you ingested.
If you shot 720/24p, it was in a 60 fps stream. If you then removed pulldown on import, that would reduce file size.
If you shot 24pNative, instead, it doesn't record redundant frames. Upon log and transfer, the remove pulldown checkbox would not be checked the file size would be identical.

PDF File Size - any way to compress further?

We have are using the Crystal for .NET export method to export a report to a .pdf file, and are having an issue with the pdf file size on a report that contains images. The images are stored in a SQL2005 database as blob or varbinary(max). The report executes a stored procedure that selects data (including images) to produce a quotation. There are input parms to decide which images to print (for example A, B or both A&B). Both types of images can appear at the line level on the quotation. Type A images print in the main report, Type B images are in a subreport. Both the main report & subreport execute a stored procedure to select an image type.
Our issue, when both Type A and B image is selected to print on a 293 line quote. The PDF file size is 44.23MB
When Type A only is selected, the PDF file size is 2.64MB
When Type B only is selected, the PFD file size is 43.95MB.
There are more Type B images that would print at the line level than Type A, but is there any way to compress this down further as it is too large to email.

You mention that you are using Crystal for .NET, but not what version; CR for .NET 2003, 2005, 2008. 2010?
Applying the latest fixes for the correct version of CR would be the first thing to do.
Next, I'd have a close look at image B as it appears to be the one adding the most "bulk". How is this image different from image A?
General tips re. images:
Save the files a BMPs.
When .jpg image is inserted into Crystal Reports it is converted into bitmap format and as the result of the conversion the report may loose some quality, scale and other issues may arise... E.g.; Crystal Reports is not so good a graphics management tool
When an image is saved as a .bmp, then there is no conversion required and thus the quality of the image should be preserved.
Best practice: save the image with high resolution and required size as a .bmp format then insert this image into Crystal Reports.
Resize the image to the smallest possible size and downgrade the DPI to 72. This will ensure your image is as small as possible and Crystal Reports will have to put in the least amount of work to display it.
Have a look ar KB [1241630 - Exporting a Crystal report (XI) to PDF generates a big PDF file|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233343331333633333330%7D.do]. This KB, may apply to your version of CR, or not. In any case, you will have to use the KB as a guide and determine what the appropriate registry entry would be for your version of CR.
One more thing. Many people like to use jpg files as they are smaller than bmp files. However, as far as Crystal Reports is concerned, this is inconsequential. The report file will be the same size if a file is inserted as a jpg or a bmp. This is due to the jpg conversion to bmp Crystal Reports does internally.

File size of Notes on iPod nano?

Hello,
my question is about the file size of notes to be handled by the iPod nano.
I have copied several ASCII text-files into the Notes folder of my iPod nano. Each has a size of approx. 20 kByte. Windows Explorer shows them in the iPod Notes folder with their original size.
However, when opening one of the text files on the iPod nano, text is only displayed until approx. 700 words (approx. 4000 characters), which corresponds to approx. 4 kByte. The larger rest of the file is not displayed, as if it was cut.
Is this an error?
Or is 4 kByte the max. size of text files which can be displayed as notes on the iPod nano?
I have updated the iPod nano firmware recently with release 1.1.
Thanks in advance for any help!

There is an online utility for doing this - will save you tons of time AND adds links so you go from one section of the larger file to the next:

PDF file size too large

Hi,
I have a report (6i and 9Ids) which contains an image (stored as a blob in the database (8i)). The size of the image in the database (and as a file) is just 750k. The image is sized to fit on to the A4 report page. If I set the desformat of this report to PDF the resulting PDF output file is 10mb in size. I need to make this report available over the web so this is too large. Has anyone got any ideas as to reducing the output file size?
I have tried the pdfcomp report parameter with no joy.
Cheers
Andy

Hi Andy,
The image you are using might be a JPEG image. In 6i and 9i, while generating the PDF file, Oracle Reports always converts the image to GIF and embed it. This image type conversion increases the file size of the outputimage and hence PDF file size increases. This is fixed in Oracle Reports 10g.
In Oracle Reports 10g, you can select the outputimageformat based on your need, using either:
1. commandline: OUTPUTIMAGEFORMAT
(or)
2. environment variable: REPORTS_OUTPUTIMAGEFORMAT
If your image in the database is a JPEG image, set the outputimageformat to JPEG. Hence, there will not be any image type conversion and the PDF file will be very small.
Please refer to the Publishing Reports manual to know more about the usage of these commandline/environment variable.
