Exporting and Compression

Help!
I have been using Garageband since version 1 came out, and I have finally gotten to the point where I can't stand the sound of my songs when they are exported to Itunes.
Is there a way to keep the initial integrity of my songs when converting them to an MP3?
My songs sound fantastic when in Garageband, but as soon as I export them to Itunes, then convert them to an MP3, (I notice Garageband3 just automatically does this now), I can barely hear my vocal tracks. It almost sounds like a really poor mastering.
Must I live with this compression, or is there a way around this?

GarageBand does not create Mp3s, it exports high quality, (Uncompressed) AIFF files Audio files from a musical project. If there is a Podcast Track in your project then GB will create an AAC file which does use lossy compression. Make sure there is no Podcast track.
BTW, converting to Mp3 (or any lossy compressed file format) will always lose quality, up to 90% of the musical information is just tossed away to create the compressed Mp3.

Aperture and Exporting and Compression (and iPhoto)

Hello All...
I recently imported an aperture project into iPhoto to create a book for a friend. In aperture, the the photos appears as 1536px x 1024px - i.e. perfectly big enough to create a 6" x 8" softback book. However, after the import, some pics appear as 768px x 512, and some as 1024px x 680px. Now, when I load the images into the book template, it says they are to low quality.
Also, when I dragged an image from aperture to the desktop (one that is the mentioned bigger size in aperture) is saved to the desktop as the smaller size. How can I export from Aperture, preferably to iPhoto, in the original, or a big enough, size?!
Thanks,
Sam

Sounds like you're dragging files from the Media Viewer that shows up when you go File -> Show Aperture Library. This Media Viewer only contains the Previews generated in Aperture. Dragging to the desktop also gets a Preview. To get the full size pics you need to export from Aperture (File -> Export and choose the correct Export settings) and import to iPhoto.

Exporting and compressing iMovie to QT Movie

I just downloaded Quick Time Pro and have tried to export a short video (4 minutes) I created in iMovie into different formats. I exported it to MPEG-4, and it worked just fine. I tried to export it as a QT Movie with H.264 compression and it took hours to accomplish. Then when I played it back, it was choppy. I am new to video editing. Is there something wrong with the program, or am I doing something wrong, or is my equipment not powerful enough to handle this?
Thanks

Hmmm.....whatever that means. I think he is just underpowered and this is an opportunity to finally get that MBP.It means you are probably correct. If this is an older G4 then playing the file is like trying to get the volume water flowing through a 4 inch pipe to flow through a 1 inch pipe at the same rate. On the other hand, converting the file is like filling a reservoir from a 4 inch pipe and then emptying it with the 1 inch pipe. It, like the computer, can do the job. It just takes a lot longer to empty than to fill.

Quality, Export, and Compression help (pic included)

I'm working on an edit of my RTW trip and am struggling to figure out some quality issues. Video was captured by 3 cameras (a JVC everio, a GoPro Hero 2, and a Droid 4). All record in HD (720 or 1080). I figured I would use the lowest common denominator and converted all the video in MPEG streamclip to be 1280x720 HD, using Apple Intermediate Codec and 100% quality. I have the whole timeline basically finished in FCE, but I'm trying to refine it now and I'm really bothered by the quality. It doesn't look HD at all...it looks really pixelated. Below is a screenshot of my viewer, which is at 100%. Note the edges where the blue arrows point-they're all jagged.
It looks decent at 100% but that is not even 1/6th of my screen. If I go up to 200% it looks like crap. Is this just because I'm editing on a 26" iMac and my screen is so big that I need 1080p or 4K to look good at full screen? When I cropped the 100% screenshot in Preview I noticed that it is 640x360 pixels...exactly half of 1280x720 like I would expect. Why is that? How do I get the quality to be like it should? Am I losing it in MPEG Streamclip or Final Cut? I haven't even started the export battle, which always infuriates me with how bad the quality comes out if the video is a reasonable file size (This video is 5m40s, I feel like 100MB or less is reasonable for streaming right?)
Thanks a ton for the help. I really want to finish this edit this week but want to make sure I do my trip of a lifetime justice.

1.) Any advice for resizing the 1080 clips?
Go to the first clip in your timeline that is 1080 and looks incorrectly sized. Double click on that clip in the timeline, you will see the clip open in the Viewer. Once it does that, in the Viewer, click on the Motion tab, and then adjust the Scale paddle until the frame is just filled. Once that is done, type Command + C to copy the clip and the settings adjustment you made.
Now go to the next instance of a 1080 clip in your timeline and click on it to select it. If there a bunch together you can hold down the shift key while you click on the clips and select as many as you want at a time. Once you have made the selection, type Option + V to paste the attributes from the clip you had just copied. The Paste Attributes window should open, and you want to check the Basic Motion box and keep everything else unchecked. Then click OK, and the clips you had selected should now all be resized.
2.) Some of the clips still have blurry frames. Now that I have the sequence totally edited and don't need to trim/move clips all the time, if I use the raw source video (not optimized for Final Cut via MPEG streamclip and the Apple Intermediate Codec) in Final Cut, will the quality be better or will it be the same/not work at all?
Final Cut Express will only work with HD material in Apple Intermediate codec. You were smart to convert the footage prior to editing. Are the clips that look blurry the 1080 clips? At any rate, you may need to render your timeline, see if any colored render bars are showing on the timeline (rendering will occur automatically when you export your finished movie).

How to export and compress a video on imovie

I have a video that is 285MB and I need to it be 50MB is this an impossible task or is there a way of doing this? Please help as the video can be no bigger than 50MB and I would still like it to be a good quality! The version of imovie I'm working with is 10.0.5.

Exporting and importing just table definitions

Hi,
I have this production database that has a huge amount of data in it. I was asked to set up a test database based on the exact same schema as the live database. When I tried to do an export (from live) and import (to test), with the parameters rows=N and compress=y, the target (test database) data file will still grow enormously, presumably because of the huge number of extents already allocated to the table in the live database. My test database of course, has a limited hard-disk space.
Is there a way to export and import the table definitions without having the target database experiencing a huge growth in the size of the tablespace?
Thanks,
Chris.

If an export with compress=n is still creating initial extents that a too large, you can still build with the import file but it will take a little work.
run imp with indexfile=somefile.sql
when imp is finished, edit somefile.sql by:
1. remove all the REM statements.
2. remove all the storage clauses (tables and indexes)
Make sure your tablespaces have a small (say 1k) default initial extent.
run imp again with rows=n
All your tables and indexes will be created with the default tablespace initial extent.

Export and Import using Named Pipes

Hai,
I need an clarification in export, import and compress of dumps using named pipes.I am using Oracle 9i RAC 9.2.0.4 in AIX 5.3. Every month i have to move list of tables from one database to another database after taking export dumps. The list of activities done by me at present are given below.
1. Taking export and gziping the dump file at the same time using named pipes.
2. Doing uncompress and import in the second database using named pipes.
We are doing compress for space constraints. Now my doubt is whether using named pipes, we can do both operation of import and compress of dump file at the same time. i.e, at the time of export itself , using named pipes, i need both import in the another database and compress the zip file. Is it possible?

Premiere CS5 Batch Export and Sony PMW-EX1R

Hey Guys!
I have multiple sequences that I need to batch export, and was wondering if there's some kind of plugin that I can use in order to do so.
Normally, I would have to select each sequence, press Command M and place it into the render queue for Media Encoder. Is there a way I can do this by selecting a batch of sequences by highlighting them and send them into the Media Encoder's Render Queue at once, rather than individually?
Also, we film on a Sony XDCAM PMW-EX1R and need a workflow to help us out with compression.
We're working on MAC PRO's and so Media Encoder doesn't have a WMV compression setting for our computers, and the MOV settings give us weird bugs on our website. So to work around this we use Compressor to compress a raw file into various MOV and WMV movies and use Media Encoder to encode F4V files.
We export from Media Encoder in h.264 with a .mp4 extension to try and replicate what our camera shoots in, but I have a feeling that that might not be the correct format to do this in because Compressor gives us this weird Frame issue where it places a single random Frame at the very beginning of our video.
Is there a better export option for Sony XDCAM PMW-EX1R users that will give us a fairly small file size and also have great quality to match our original footage, as well as not having us have to wait long periods of time for export?
We've tried
Quicktime ProRes 422
Quicktime Uncompressed
Animation
Jpeg Sequence
And they all gave us extremely large file sizes (which I understood since they're lossless) and H.264 seemed to give us as big of a file size as FCP did with it's MOV files which is what we're trying to do.

So you're saying that I basically have to pick either using a file that isn't good for delivering content, or selecting a file that's big in size and long to export?
Well, look at it this way: if you want the highest quality output, you want to start with the highest quality source. If you're exporting from Premiere or through AME to a deliverable file--like a WMV or an H.264 MP4--you're all set, because you're accessing the original source media and unrendered effects as they exist in the Premiere Pro sequence. If you're exporting from a different app, you want the most pristine source file to create your deliverable.
Let's say you make apple juice. If you get whole apples from the orchard and press them, you make some mighty delicious juice. However, if you're trying to cut down on shipping costs, and you have the farmer smash the apples into chunky apple sauce so that you can fit more apples in the same amount of space, you can still make juice... but it won't be quite as tasty It's sort of the same with encoding...
An intermediate file will take up more space, because it's uncompressed (or less compressed), but it shouldn't take as long to generate, either--again, because you're not compressing it or you're compressing it less than your final deliverable. Obviously, there are dozens of codecs you could potentially use, so there's a fair bit of experimentation you need to do to determine the best combination for your purposes. There is no "one size fits all" when it comes to encoding, unfortunately; it's a path fraught with compromises.

How to export and reimport clips maintaining best quality?

I'd like to ask a few questions.
(1) I have several subclips in FCE that I would like to export, so I can import them back into FCE as individual clips, separate from the original capture. I would also like the option to use the exported clips in iMovie project. The most important thing is to save the clips at the highest possible quality. I ran into a problem when trying to import the clips back into FCE.
First, I tried exporting clips using File>Export>Using Quicktime Conversion... with the following options:
Video Settings:
Compression Type H.264
Quality: Best (the slider in the Settings window I dragged all the way to the right for Best quality)
Key frame rate: 24
Frame Reordering: yes
Encoding mode: multi-pass
Audio Settings:
Format: Uncompressed
Sample rate: 48 kHz
Sample size: 16
Channels: 2
Prepare for Internet Streaming <unchecked>
The clip was saved to disk. I didn't open or modify the clip at all.
Then I tried using File>Import>Files... but when I tried to import it, I got this error:
"File Error: 1 file(s) recognized, 0 access denied, 1 unknown."
So this is the problem I'm experiencing. Can't re-import the clip into FCE (it imports into iMovie fine, though)
Questions: Am I using "wrong" settings? Why is this happening? How can I export and reimport clips while maintaining best video and audio quality?
(2) A couple related questions: Some of my original source video was recorded at 12-bit quality (32 kHz). I know 16-bit is best (48 kHz) but the camera I used came with factory default 12-bit (and as a novice I didn't know to change it until several months later).
So here are my questions.
(a) If I export these clips using audio export settings at 48 kHz instead of 32 kHz, would that cause any problems?
(b) Would those clips then be recognized by FCE and iMovie as having 48 kHz audio even though it was originally recorded at 32 kHz? (I know the quality will be no better, but I've read somewhere that using 32 kHz audio can cause some problems with out-of-sync audio, particularly in iMovie. My hope is the new clip with the 48 kHz audio will circumvent such problems.)
Thanks for any assistance you can provide.

TSchneider: Thanks again for your valuable reply. I have a few follow-up questions.
My first set of questions is about rendering audio to 48kHz in the timeline.
Almost immediately you'll notice that FCE has tagged the
entire audio track with a red bar meaning it will
need to be rendered (if you try to play the clip from
the Canvas controls you'll just get beeping or very
low quality sound). Go up to the Sequence menu and
select the Render All (or Mixdown) command and FCE
will transcode the 32kHz audio of your clip to the
48kHz audio of the sequence it's sitting in.
I followed your instructions and everything seemed to work until I got to the passage above. I dragged the subclips into the timeline. The clips appeared in the timeline but there was no red bar. If I chose Render All from the Sequence Menu, nothing happened. If I chose Export to Quicktime Movie, however, it takes several minutes, apparently rendering the audio and video. If I chose instead, Print to Video, the red bars do appear and the rendering process again gets going. There is a small progress bar for both operations in the center of the screen with a percent done and estimated time remaining.
Question: Why doesn't the red bar appear as soon as the clips are in the Timeline?
Question: Why doesn't Render All (or Render Audio) work? It would be much easier to walk away while all the audio rendered into 48kHz and then come back later to save the individual clips to disk.
My second set of questions pertains to the possibility of using Export>Using Quicktime Conversion as a substitute for Export>Quicktime Movie, mainly for academic instead of practical reasons.
If you export a clip directly from the bin "Using
Quicktime Conversion" there aren't any suitable
conversion video/audio formats that would give you
both video in the right format (for iMovie) and
transcode the audio to the sampling rate you want.
I understand your description of rendering the audio files in the timeline. If only academic, I was trying to see if I could duplicate the results using using Export>Using Quicktime Conversion. I chose Quicktime Movie as the format. The video setting was DV/DVCPRO-NTSC. The audio was uncompressed with 48kHz rate. This created a Quicktime movie file with these formats. If I opened the quicktime movie file in Quicktime and checked the info on the file, the audio was indeed 48kHz.
Question: Does this mean that the Quicktime Conversion process rendered the 32kHz audio to 48kHz audio prior to writing the file? If so, it would seem to bypass the need to render the clips in a sequence (although if I could render all the clips in the sequence at once, while I was away from the computer, it would be faster than rendering and saving each clip one at a time).
Question: When I exported a clip this way, then imported it into iMovie, the original capture date/time info was missing when I got info on the clip. However, when I save the clip using Export>Quicktime Movie, the date/time of capture was still present. Would there be any way to preserve this date/time of capture info when using Export>Using Quicktime Conversion?
Question: If I decided to Export>Using Quicktime Conversion with the above settings (DV/DVCPRO-NTSC, 48kHz audio) there are other options I'm given pertaining to the video settings. There are settings for Compressor Quality, with a sliding bar where you can choose Least, Low, Medium, High, and Best quality; and there is Scan Mode (interlaced or progressive). How does one choose among these? If you want the best quality exported clip, I suppose you would chose best quality, but what scan mode is "best" for my purposes -- interlaced or progressive?
Thanks a lot for your help. I'm learning a lot!

LR5 - when exporting and uploading to FB photos look very bad

I just upgraded from LR3 to LR5 - when I export and upload to Facebook - the photos look horrible. Very unclear. Looks like they got compressed in a strange way. I am doing everything the same way I did it in LR3 but getting differnet results. Any help would be very appreciated.

I am using LR5. So does that mean everyone using LR5 will have this problem.
When I export to my desk top they look fine. But when I send them throught eamil or through FB they get all weird looking. I am so confused.

Why Does idvd take my 26.2gb imovie file and compress it so small?

Please help. I've created a 17+ minute long imovie file that is 26.2gb. When I view the file information in idvd it says that it's only 0.6gb.
I've already burned a test copy and it looked way too compressed. Like a bad jpg file. From idvd, I burned 'best quality' to a disc image and toasted it. I know that idvd decides who to do the compression in some complex way, but is there another method to not have so much compression?
Thanks...

Robert,
DV (as normally exported from iMovie to iDVD) runs
about 13 GB per hour. You say your content is 17
minutes and 26.GB - what CODEC did you use?
DVDs are in MPG-2 compressed format. In Best Quality
mode iDVD will take 120 minutes of DV content and
compress it to about 4 GB. So 17 minutes of content
could be about .6 GB.
F Shippey
Thanks for your reply. I didn't pick a codec. I just clicked create idvd from imovie and it did it for me. I've made at least 10 other dvds and haven't seen this much loss of quality before. I'm just not sure why...
0.6 was project size and I guess your math is right, but I've very disappointed with quality.
Thanks,
Bob

Best settings for exporting and dropping a MOV file into iDVD7?

I have a movie (originally shot in HD), made in iMovieHD6, and that I'd like to export and drop into iDVD7. *What settings would the brain trust recommend?* I cannot seem to get iDVD to render a good version through direct export from iMovie. (As a side, I wonder if it is because I started this process by bringing AVCHD files from my camera into iMovie8 and "going backwards" to iMovieHD6.)

I have used Pro-res from Final Cut Pro into iDVD and it works.
*This is from iDVD help menu:*
Video and image formats that work with iDVD
You can use these movie and graphic formats in iDVD:
◼
Most video or image files supported by QuickTime (see the list of unsupported QuickTime formats below)
◼
16:9 widescreen formats
◼
AAC, MP3, and AIFF audio files
◼
Any format from iMovie: DV, high-definition video (HDV), MPEG-2 SD, MPEG-2 SD, MPEG-4 SD, MPEG-4 HD, and AVCHD
High definition video is converted to work with the format of your project. iDVD supports using 16:9 widescreen video; therefore, when your DVD plays on a DVD player that supports widescreen format, the footage appears in its original aspect ratio.
The following video and image formats are not supported in iDVD:
◼
Copyrighted or protected videos.
◼
Movies saved in thousands of colors using the “none” compression setting in iMovie.
◼
48-bit color images (16 bits per color). To use source files in one of these formats in iDVD, save them in a supported format.
◼
Aurora uncompressed files. For best results, export Aurora clips as DV-format video before importing them into iDVD.
◼
QuickTime VR, MPEG-1 or MPEG-2, Flash, streaming or encrypted movies, or QuickTime spanned movies. You can’t add MPEG-1 or MPEG-2 files to an iDVD project because they don’t contain standard video tracks.
◼
QuickTime Fast Start movies. (Fast Start movies are intended for Internet playback.) When saving a QuickTime movie for use with iDVD, click the Options button in the QuickTime Export dialog and make sure that the “Prepare for Internet Streaming” checkbox is not selected.

Problem during export and data

I have 60GB of mount point OS level but my estimated dumpfile size 150 GB.
How i will take the back up of the database using Simple export and Datapump utility
We are using Red hat Linux OS and database version 10.2.0.4
I am new to oracle .

>
Yes, use RMAN for backups. This export won't let you restore everything if your database crashes after an hour your export finished. You would have lost an hour of data. With RMAN, it will take hardly 1/5th of the export time and it is reliable when recovery situation occurs.
By the way, if you use traditional export (not the datapump), you can use pipe to compress the data as the data gets exported.

1. xaa 4gb
2. xab 4gb
3. xac 4gb
4. xad 3gb
i have import these dump file here in Unix server. i found some document to import the split and compressed dump
i follow the below steps
1. copy all 4 files into a directory
2. then i used commands
rm -f import_pipe

(import_pipe file created in the current diriecty)
nohup cat xaa xab xac xad | uncompress - > import_pipe & ( Process number created like 23901. we need to wait till complete the backgroud process before giving IMPORT command?)
then i give
imp userid=<connection string> file=import_pipe full=yes ignore=yes log=dumplog.txt
then it shows the imp-0009 error...
pls help me resolve this issue.
Thanks in advacne

Pl post details of OS and database versions of the source and target. You will have to contact the source to determine how these files were created. It is quite possible that they were created using the FILESIZE parameter (http://docs.oracle.com/cd/E11882_01/server.112/e22490/original_export.htm#autoId25), in which case the import process can read from these multiple files without you having to further manipulate them.
