Unable to compress.

I'm new to Leopard as of two days ago. I am trying to compress a file, but the .zip file that results is the same size as the original, which I can't e-mail. I've checked permissions for the file as recommended by Mac Help, but the file still will not compress to a smalller size. Is there something I'm doing wrong or that I just don't know?

Not in the sense you're talking about (lossless file compression to .zip). A movie can be compressed lossily through video compression (programs such as Quicktime Pro or Compressor) which results in a smaller file size, with some degradation of video quality depending on the compression type (eg, to MPEG-4).
The same applies to audio - you can try to compress an AIFF file to .ZIP, but probably won't get the file much smaller; however, if you use iTunes to (lossily) compress the audio to mp3, you will get a nice size saving.

Unable to Compress the request of a Cube

Hi All,
I was trying to compress the cube data,At one request I got stuck. When ever I try to compress that request manually, but it is unable to compress the request and sends the following job logs
Job started
Step 001 started (program RSCOMP1, variant &0000000000190, user ID XXXXXX0006)
Performing check and potential update for status control table
No requests needing to be aggregated have been found in InfoCube 0XX_X01
Compression not necessary; no requests found for compressing
Compression not necessary; no requests found for compressing
Job finished
After further analysis, I observed the request which I am compressing , has an selective deletion.Since its is 2year old data I would like to compress the data,please suggest is it possible to compress,If the request has selective deletion.
please suggest.
Thanks & Regards,
Abdul

Hi Abdul,
Check that, if the cube that is being compressed feeds the data to a different InfoProvider, if yes then complete that laod first and then do the compression. this might be the reason sometimes. if the cube is not feeding anything currently try compressing the request again.
In some cases ,when the compression is manually performed (in the tab collapse of the cube) no compression would be done. In those cases you can try creating a process chain with only the compression step. This often solves the problem.
If both the above process don't solve your problem,
Try the SAP note :407230 (such problems occure after installing SP15.)

Unable to compress a request.

Hi experts,
I am unable compress a request by manually and by scheduling in the process chain also it is not compressing.
when i open the collapse tab it saying No valid request exists for compressing
then i entered manually with request id. job finishing without compression and i found in the job log(SM37)
*No requests needing to be aggregated have been found in InfoCube
*Compression not necessary; no requests found for compressing
*Job finished
in 10 seconds.
Process chain is also completed successfully without compression.
i don't know y it is not compressing the requests ?
Thanks in advance.

Hi,
Note: Is "Tick" mark there against your request in requests tab?
If you are able to see your request in requests tab as not compressed, then delete this request and reconstruct it back from the Reconstruction tab. But please check in reconstruction tab to make sure the same request is available.
After the above activity, you can try to compress this request.
Hope you understand.......

No sound and am unable to compress

I have a Sony Handycam and have noticed that when I download my videos to my desktop there is no sound. I downloaded MPEG Streamclip and it pretty much took care of the problem, but it has also created new issues.
A. Once I convert the video through MPEG I am not able to put the movie into imovie, whereas if I don't convert it (leave it w/out sound) then I can.
B. If I were to try to import clips directly from my Sony Handycam the program says I still need to plug in my camera (even though it is). It's just not reading it. I don't see a way to set it to "VCR" as I've seen demonstrated in the demo.
I am ultimately trying to compress some videos to post on youtube and also would like to burn dvd's. But it seems that beacause I can't ge through imovie I am also not able to work w/the videos in idvd.
Also, is there a way to convert .mpg's from my sony digital camera (I took some small videos w/it. This isn't my video cam)? When I pulled those videos off the camera they were mpg's and I'm not seeing a way to convert them.
Any advice would be appreciated. I've been working on this for about 3 months and have made absolutely no progess. *pulls out hair*
Thanks!

Sorry for all the edits, I'll just tack on the new question here.
With SC open to "export" my setting choices are as follows:
Compression - set to: DV (DV25)
Standard - set to: NTSC, 720x480,29.97fps with PAL option in drop-down box. I'm think PAL is for non-US DVD's?
*Aspect Ratio* - set to: 4:3 with a 16:9 option in drop-down box.
*I also have an option to "check" any of the following:*
Frame Blending
Better Downscaling (currently checked)
Deinterlace Video
Resample Audio to 48KHZ (currently checked)
Split DV stream in Segment (use this option to prepare the stream for imovie) currently not checked but I now realize it needs to be.
*"Deselect (the following) for progressive movies -*
Interlaced Scaling (currently checked)
Reinterlace Chroma (currently checked)
Rotation - set to: No
Zoom: 100% X/Y: 1 Center: 0,0
Cropping (currently unchecked)
Presets
*Reset All*
Adjustments...
I'm not sure what most of these settings do/affect. Is there something online that explains each of these steps? To export an mpg1 for use to burn as a dvd (just copy directly from desktop, not using a program) or for use in imovie/idvd I'm not sure where the settings need to be before I export.

Permission denied - unable to "compress" file

Hi I have a weird scenario which I would need help on.
SunOS mysvr 5.10 Generic_127127-11 sun4u sparc SUNW,Sun-Fire-880
I have a user "myuat" which belongs to a group "pc"
# id

and in /etc/group

I am running a compress command to compress a file in a directory and I get permission denied

TO:

then I will be able to compress the file, why? I wonder why "myuat" id is not able to compress file eventhough it belongs to same group?
----rwx---+ 1 myuat pc 42120 Aug 5 00:23 mytxtcom.20080804.Z*
Any idea? Please help.
Thanks

Were you the root user when you compressed the file?
It looks like the user 'myuat' does not have permission to write to the '/myprod/mycor/mycom/myarch' directory. You need to have write permission to the directory in order to compress a file in it, even if you have permission to write to the file itself.

Unable to compress non-cumulative infocube with 0DOC_NUM

Hi Gurus!
I'm working on a retail project. I've created an infocube based on 0RT_C01 to keep the stock movements. It is a non-cumulative cube.
After the load of the initialization data (2lis_03_bx) ,historical movements, the initialization of 2lis_03_bf, the daily delta loads take about 10-11 hours to complete.This is because the cube has not been compressed due to the existence of infoobject 0DOC_NUM. 0DOC_NUM is of the lowest granularity and so compressing on 0DOC_NUM will not yield any performance benefits. But this has impacted the performance of daily delta loads. Also,the report that uses this cube take about 3-4 hours to open initially.Sometimes a timeout occurs.I've checked in ST22, ST21 and no errors or dumps appear.
Is there anything I can check to speed up the process?
Thanks!
Lucia

Hi,
Compressing the request containing the opening stock that was uploaded. Make sure the "No marker update" indicator is not set. Please consider note 643687 ,before you carry out the compression of requests in stock Info Cubes!
After successfully uploading the historical material movements, the associated request has to be compressed. You must make sure the "No marker update" indicator is set. This is necessary because the historical material movements are
already contained in the opening stock.

Unable to compress to mp4 or quicktime with compressor 2

After I upgraded from compressor 1.2 to compressor 2.0.1 I found out that the mpeg2 quality was not as good as that of compressor 1.2, however the quality of mpeg4 using a compressor 1.2 preset was as good as that of compressor 1.2. Trying to improve mpeg2 quality I deleted all the compressor 1.2 presets as recommended by Apple. Now the mpeg2 quality is very good. However when I try mpeg4 or quicktime, compression always fails with the following message: "Failed: 3x crash service down".
The resulting files cannot be opened with quicktime (as expected) with the error (-2048)
Does anyone know what the problem could be? I have tried everything I could find in this forum but nothing has worked. Reinstalling compressor 1.2 will not work either.
Thanks

I'd suggest that you look in your console and system logs to see if there are any error messages or warnings that might hint at what could be going wrong. You can view these logs by going to the Apple menu and selecting "About This Mac" and then "More Info..." This will bring up the System Profiler and then under the left-hand column ("Contents") go down to "Software" and select "Logs."
You will likely find a lot of messages in both of these logs, even some warnings that have nothing to do with your particular problem. Just scan through the information looking for anything that seems related to Compressor, FCP, Qmaster, QuickTime, or any warning about a missing or incompatible component that could be related to the above.

Compressing attachments in entourage email

I am unable to compress attachments in my entourage email. I have Stuffit Expander installed, and I still can't compress pictures and video. Is there something else that needs to be done?? Please help
Powerbook G4 Mac OS X (10.4.6)

In Mail for the iPad, there isn't a typical paperclip icon that most associate with attaching a file.
On an iPad, you first need to find the file on the iPad. It could be a picture, a document, etc. When you find that file you will want to use the 'Send To' option. The icon is a little square box with an arrow jumping out and pointing to the right. After you select this, you will want to send it to 'Mail'. iPad will now create a new message with that file attached. Now, you are free to type in the reciepent, body of the message, and send it on it's way!
Hope that helps.
Take care,
Daniel

Re: Newbie has compression question

I downloaded all my cds onto my computer using apple lossless. My 2G Nano maxed out at 70 songs. No good, obviously. I don't mind losing some sound quality by compressing all the songs, but is there a way (short of selecting manually each & every song that is over 128) to compress only those that need to be. Every time I select all it goes back to the beginning and starts compressing. I have several copies of the same songs (makes for a messy library) up until a song that teh computer is apparently unable to compress, so it stops altogether and won't compress anymore. I just want to make them all smaller, fit as much as I can on my nano, and go on my merry way. Any ideas?

Re-rip them from your CDs at the preferred setting?

Problem with compression with flash cs3

our web developper says that she was unable to compress image
with flash cs3 any idea why and what i can do for her ?

Gotcha. You must have started the document in AS2, then
changed the
publish settings. Each version of the language has its own
version of the
FLVPlayback Component (written in the relevant language).
Start over and
compare two compleley new FLA documents: make one for AS3 and
one for AS2.
Open the Components panel and note the differences between
the two. There
are a different set of Components depending on the language
chosen for the
document. Drag the FLVPlayback Component from the Components
panel in an
AS3 document, and you'll have the AS3 version.

Logrot.pl (v.4.4) issue on solaris 9

logrot.pl does not check diskspace before doing a copy process of syslog_info; if there is not enough space, the copy process fails and the content of syslog_log is lost;
I know, that the error handling of such a script cannot take respect on each and every possible error that could appear but in case of the syslog file I would say it is such an essential file that it would be great that the loss of the content could be avoided.
currently I am unable to test if this issue is present in the current version but I found it to be valid in LMS 3.2 on solaris 9; here is the confiuration of logrot.pl
/var/log is configured as the backup directory,

Disk Utility: after creating the .DMG (compressed image) When "scan image for restore" finishes it displays "unable to scan (internal error)". Since the process was scanning for about 1 hr is this a fake warning?

External 500GB drive is partitioned with 400GB for Mac OS extended (journalling) and 2nd partition formatted today as "ExFAT".
Yesterday I tried to create a disk image of my HD to no avail - this was compressed on a FAT partition. I got a warning after running the <scan image for restore> saying "unable to scan (internal error)"
I rang Apple support who suggested formatting a partition as MAC OS extended (journalling) and choose to save the image as "read/write'. The image process stopped writing at about 200GB and then the file size jumped to 499GB (ie the size of the HD). But the process did nothing for about an hour so I foce quit disk utility (as suggested by apple support)
My current attempt was to format the external drive again; this time with a 400GB Mac OS extended (journal) format; plus a 100GB ExFAT format partition. The new image was created after about 2.5hrs with a compressed size of 149GB. However, after running the "scan image for restore" facility I got the warning message "unable to scan filename " (internal error). The process was scanning the image file according to the progress bar - this took about hour - thus the warning is a puzzle.
If anyone can say more about this error I would really appreciate knowing tips for using disk utility. The screen grab is below.
"unable to scan filename " (internal error)
thanks

Thanks for a quick reply <baltwo>. You’ve answered that it is not a fake message!
fyi: I thought that I would use my external Buffalo for two purposes; namely the smaller ExFAT partition for copying stuff to my win7 netbook. The larger partition was to be used as my imac image of SL. So this was my first attempt at using disk utility - the idea being to hold an image backup at another location. Plus I now have the Lion thumbdrive ready to upgrade from SL and so being cautious wanted to have a SL image backup
Anyway I followed the apple instructions using my mac 10.6.3 install DVD but it would appear from other discussions that <unable to scan (internal error)> is not unique to me.
I’ll get back to apple telephone support for further advice.
I would though be grateful for an “idiots’ guide to making an image backup of my internal HD that runs SL 10.6.8
eg should I have just one partition on the external USB drive? format it as Mac OS extended? create the image as compressed or read/write? Basically I’ll do whatever will work!!
thanks again

Sharing video; unable to publish to YouTube and cannot compress enough to send as attachment in email

I have followed the instructions for sharing but I am unable to publish 3 minute video (and it is not in HD). What am I missing? I also cannot seem to compress it enough to send as an attachment in an email. Any suggestions?

Export it in the size you wish and then, after you have the .mov file, you can easily upload it to Youtube. I can't imagine a 3 minute video that would be too large for Youtube to accept. Sometimes, iMovie (as well as iPhoto) seems to have problems "sharing" to other applications. I don't even try anymore. It is almost as easy to export the video and then upload it where ever you wish.

Unable to compress.
