What compression type to use when exporting?

I need to export a Final Cut Pro Movie File to a QuickTime Movie file. There are so many copression types to choose from. Which should I use so that people with both Mac and PC could open the file? Some friends have complained that they can´t open files that I´ve exported using H.264 which is the default I get in QuickTime.
thanks in advance

Backward compatibility has always been a QuickTime strong suit. Files made in version 3 still open just fine in version 7.
But H.264 (and the preset export options) make this a bit more confusing.
MPEG-4 Video codec will open in version 6, or higher and, since version 6 has been available since 2002, it is a very good chance your viewers have version 6 to view it.
Older machines that can't be upgraded to version 7 or viewers that still haven't upgrade their version of QuickTime beyond version 4 (Win 95) would like to view Sorenson 3 Video codec.
Don't bother with any conversion to AVI as the QuickTime export options (Cinepak) haven't been used since Win 3.
If you have a lot of videos to share or are making files to be used in a Web page you'll probably get the best results by choosing:
Export > Movie to QuickTime Movie
and choosing MPEG-4 Video codec. These .mov files work just fine on the Web and also in other players (iPods, etc.) as long as you don't exceed the specs for iPod.
Learn more by experimenting with one minute exports to various codecs and settings.

What Rendering intent is used when exporting with a different color space?

Hi,
I would be ever so grateful if any one can tell me what rendering intent is used by LR4 when exporting using a custom colour space as there is not an option as there is with the print module.
Thanks.

The rendering intent in the Export dialog is Perceptual.
Actually, an RGB color space to RGB colorspace is always only Relative Colorimetric...and adding Perceptual would only work with certain V4 ICC color spaces (you can find perceptual V4 color spaces for sRGB and ProPhoto I think but I'm not sure they would work in Lightroom anyway).
When using an RGB print output profile you can select either Perceptual or Relative and have the intents actually applied.
True.
The case of interest to me is when I have to print a lot of files using a third-party profile and maintain the original filename so it appears on the back. That is why I made the request more than a year ago.
The problem with the Print module is that it clobbers the filename but does allow 2 choices for the rendering intent. Having to deal with weird filenames creates a mess when matching, say, 50 prints with custom notecards.

What PPI should I use when exporting for a video project?

I shoot RAW photos. I like and use Premier Elements 11 to make video. Frequently I insert photos in the videos and enjoy using the Pan and Zoom technique (frequently credited to Ken Burns).
Resizing photos helps Premier Elements to run smoothly. The LR Export command makes it easy. Using PSD files works well in Premier Elements. However, I am confused about settings.
My understanding is that if no Pan&Zoom or cropping is to be done in the video the export should be 1920x1080. If Pan&Zoom is planned, the setting should be higher by about 50%. LR makes it simple by letting you specify the "Long Edge" so the setting would be 2880. The short edge will match the original.
What about "Pixels Per Inch" for a HD 1920x1080 video project that may be played on a big HD TV or smaller YouTube? There is plenty of information about PPI for printing and computer monitors, but not HD Video.
Here is screen capture for reference:
What should the pixels per inch be set at to match 1920x1080 video? The 140 setting is a complete guess!
Thanks in advance!

The above sentence from your first post is the correct answer with a few changes as to what settings you need to use in LR's Export module.
Anytime you "resize" an image it will lose sharpness unless you apply Output Sharpening. I have no idea if Premier Elements applies sharpening, how much it applies, or how much using large raw images slows it down. The best suggestion is for YOU to resize the raw images and apply Output Sharpening that meets YOUR taste as to "crispness." That way Premier Elements will use the properly sized TIFF or JPEG images (no PNG Export in LR) with no further modifications.
For 1080p (1920 x 1080) Videos:
Don't use the 'Long Edge' option in LR's Export module since you want both portrait and Landscape images to have the same height. Instead simply enter W: 1920, H: 1080, and Resolution as mentioned doesn't matter. For the Output Sharpening LR's Screen Standard setting should work fine, but review the resized images at 1:1 and adjust to your taste. LR's Develop module Sharpening settings should NOT be used for this purpose. This is for the initial "capture" sharpening only.
As you mentioned when using Zoom & Pan you will want to increase the file size proportional to the actual Zoom setting you are using inside Premier Elements:
150% = 2880 x 1620
200% = 3840 x 2160
300% = 5760 x 3240
For best results I'd limit your Zoom to 150%, especially if you’re having performance issues. You also don't want to make your image larger than its native camera raw resolution, which will reduce the sharpness. For higher Zoom settings simply Export the images full-size without using ‘Image Sizing’ or ‘Output Sharpening.’ Use 'File Settings' JPEG, sRGB, with 80 Quality setting, which will provide good results.

What compression type to use for disk image files

Hello all
I was wondering if a more experienced user than me could give a recommendation as to which compression format I should use to compress an image I made of my / partition. I used dd to make the image file.
For me, (de)compression time is more important than compression ratio (size), but I'm of course looking for a good blend of both
Thanks for any advice

If you have a multicore processor, use pigz instead of gzip etc. Start with this app and only after you're not happy with it, look for one that's faster / compresses better.
BTW, do you have a lot of incompressible data in there? Movies, pics, music and already compressed files won't compress any more.

How can I change (or select) what is being being used when I share, as the file cover. When I Share lets say "Master File" i want to select a frame that is used as the file cover. So when its on my desktop I see this image as the file icon.

I don't think Finder does this (I've tried).
iTunes does though. Where you can set artwork or the "poster frame"...
This may not be what you want but if it helps, I know 2 ways do this is
Open the video in QuicktimePlayer7 | View | Set Poster Frame (even then, you might need to save it as .mov (ie in a 'mov container').
Drag the file into iTunes and set the artwork (as in http://www.dummies.com/how-to/content/adding-album-cover-art-or-images-in-itunes .html)
From there, iTunes will use that frame as the "poster frame" ie the photo/frame that shows when you browse your videos. Which is what you want, but limited to iTunes.
When I do either of these above, the frame I set does not show when exploring files in "Finder" (or in the other Explorer tool I use called "Pathfinder").
So it maybe, that exactly what you want, is not possible.

What message type to use for syndicating data back to R3 from XI

What message type to use for syndicating data back to R3 from XI. It gives a Message type IDOC error code 51.

Hi Rehman,
You are getting error 51 which means "Error: Application document not posted".
This might because of two reasons:
1. Your IDoc doesn't contains all the mandatory fields required by the inbound function module to post the IDoc.
2. You have assigned wrong inbound function module to post the IDoc.
Please check these cases.
Hope this will help you.

What port numbers are used when creating temporary queues

Using the following code as an example, what port(s) are used when creating temporary queues? Is it a range of ports? Is it random? And is it configurable? If you have any insight on this, please let me know. Thanks.
QueueConnection con = connectionFactory.createQueueConnection();
QueueSession session = con.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
TemporaryQueue replyQueue = session.createTemporaryQueue();

The only ports I know about are the defaults ports:
JMS 7676
IIOP 3700
Are these the only ports that are used, even for temporary queues?

What is the best audio file type to use when ripping CD's?

Very new to this. When I rip my CD's to my computer, what file type should I use? Pros and Cons of each if you could too please? Thanks!

The best bitrate and encoder is the one that suits you best.
 Apple Lossless will give excellent sound quality, but at a file size that is much larger than mp3 or aac, so the trade off here is not as many songs will fit on your iPod.
 You should probably start by encoding a piece of music you are familiar with, in either mp3 or aac at something like 192kbps, listen to it, then try again at different bit rates, both lower and higher, to see if you can hear a difference in sound quality.
  If you can’t hear the difference in sound quality between various bitrates, then the lower one will suffice, and you can store more songs on your iPod. Try this in both encoding formats. You could encode the same song several times in iTunes under a slightly different name (just edit the song in iTunes and add the bitrate after the song title), transfer these songs to your iPod and do some comparative listening. Then you can make an informed decision about which format/bitrate is best for you.
  Yes it’s time consuming, but much better to rip your cds at decent sound quality now, rather than decide much later that you are not satisfied, and have to rip them again.
  And incidentally, a song of the same length, encoded at the same bitrate, gives an almost identical file size whether it be encoded in aac or mp3.
  Where the space saving issue comes in is because many people say that if you encode a song at 128kbps in aac format, then the sound quality is as good as the same song encoded at 160 or 192kbps in mp3 format, therefor using the aac version gives a smaller file size and allows you to store more songs on your iPod.
  It's very subjective and you shouldn't let anyone tell you what to use.
  Let your ears be your guide.

What settings to use when exporting HD into QuickTime Movie

This help call goes out to any Mac user with Final Cut. I need help!!!
I have a Mac G5 and use Final Cut Pro V. 5.1.4. I Just bought a Canon XH A1 and filmed a few test shoots. Then downloaded to FC Pro. I have been trying to export using QuickTime Conversion. Every setting I have tried comes out more or less square. HELP!!!!
My Settings:
In Easy Setup - HDV - 1080i60 FireWire Basic
Under Sequence the setting is:
Frame Size - HD (1440X1080) (16:9)
Pixel Aspect Ratio - HD 1440X1080
No check mark in Anamorphic 16:9
Field Dominance- Lower
Editing Timebase - 29.97
QuickTime Video Settings:
Compression - Motion JPEG B
Under Export - using QuickTime Conversion - QuickTime Movie - Options - Video Settings:
I tied:
HDV 1080i60 and 50
Motion JPEG A and B
DVCPRO HD 1080i60
All settings come out squarish!!!

Hi Patrick,
Thanks for the info. But I can not get any setting to come out looking widescreen. All settings come out square looking. I have tried every setting I can think of but all the QuickTime exported movies come looking like (i.e.: 800X854) more box than widescreen. I think it must be some setting I do not know about or some combination or possibly the capture setting (easy setup).
Thanks for your help.

What compression settings to use from finalcut4.5HD to quicktime to toast?

I've been looking thru the forums and there are a lot of questions pertaining to this issue but I'm still having issues so here goes again...:)
I'm trying to burn quicktime movie files that I created in Final Cut 4.5HD onto a data dvd. When the files are created and played from the computer, they play fine. But when I burn them onto a DVD, a few of them are really jerky in motion and sometimes the video stops while the audio keeps going. I've been reading on Apple's forum that it may have to do with the compression or the data rate at which the file is created from FinalCut. Any suggestions on what export settings to use out of Final Cut?
I tried using - File - Export - Quicktime Movie (setting: current settings...include: audio & video...make movie self-contained)...created a .mov file but it was large and jerky on the data dvd when burned...
I also tried using the - File - Export - Quicktime Conversion option as well with different variations of the settings...(i.e. quicktime movie/mpeg-2/mpeg-4 with different compression types (dv/dvcpro-ntsc/none/video/mpeg-4/animation), key frames, compressor quality, etc)...The only thing I wasn't sure about was the data rate (i.e. automatic or restrict to?....and if I use the 'restrict to' what's a good amount?).......i
I have played around w/ these settings and still get jerky motion when played on a data dvd...the only ones that played correctly were the ones created thru the mpeg-2 format setting but these were .m2v files and are separated from the audio .aiff files...(the person getting the file needs the format in .mov format)...
My purpose for these particular exports are to create relatively small but good quality quicktime files that someone else can take and post on the web
I would also like to know what settings I should use if I wanted to 'backup' files for archival purposes in case I needed to go back and use the footage for editing purposes (in this case, file size the normal 720x480).
I'm using quicktime player 7.04 basic (not pro)
I'm using Toast 7 to burn the files. Just been dragging the files onto the Data Tab - Mac & PC format.
Thanks in advance!
powerbook g4

Just use the movie project file in Toast, it is DV and Toast will transcode it to MPEG-2 when authoring the DVD. DOn't encode to a lossy format before Toast as Toast makes MPEG-2 which is lossy enough already without two compression cycles.
You also don't use Toast to just burn a data disc as playback of a very high bitrate QT file might be more than the DVD can deliver.
Use the Toast video tab, DVD video button and add the movie project to the drop area or select from the media browser. Read the Toast manual as well.
For backup - export the project to a fresh DV tape or store the raw DV files on a external hard disk - do not compress it to some QT format and expect it to be "archival" footage to re-edit later - it will look terrible ( and while some people think encoding it to H264 is a way around this - it isn't and takes a ton of time to encode to H264 anyway).
$5 DV tapes are the best backup in addition to a 2nd hard disk.

What PDF settings are used when creating DPS articles?

When you create a PDF file using Acrobat Distiller or InDesign you can modify settings such as font subsets, image down-sampling and compression which will have an impact on the final file size. Does anyone know what settings are used when articles are rendered in PDF format in DPS and can the settings be modified? Specifically, what type of compression is applied to images? If I were to place two images on a page, a png and a jpg with medium quality, would they be embedded in the PDF as is or re-compressed in another format and/or level of quality?

Thanks for your help.
So images placed in an InDesign retain their original file format and are unzipped when the article is loaded in the app.
I'm assuming that if compression is applied to the original image files it can have an impact on performance. If you were to use jpeg files in a document they would need to be unzipped and decompressed. I've read other forum posts that suggest the iOS jpeg decompression engine is too slow to present a fluid user experience in a DPS app. The combined processing time of unzipping and decompressing jpegs files may steer me towards the png format.

What are type defs used for?

I am learning about type defs and wanted to ping the community to get a feel for what expanse of things they are useful for. Any and all comments are welcome.

Using LV 2013, 2012
Don't forget Kudos for Good Answers, and Mark a solution if your problem is solved.

I found this (from LV Help) enlightening as to the differences between typedefs and strict typedefs:
Type Definitions and Strict Type Definitions
Use type definitions and strict type definitions to link all the instances of a custom control or indicator to a saved custom control or indicator file. You can make changes to all instances of the custom control or indicator by editing only the saved custom control or indicator file, which is valuable if you use the same custom control or indicator in several VIs.
Type Definitions
Type definitions identify the correct data type for each instance of a custom control or indicator. When the data type of a type definition changes, all instances of the type definition automatically update. In other words, the data type of the instances of the type definition change in each VI where the type definition is used. However, because type definitions identify only the data type, only the values that are part of the data type update. For example, on numeric controls, the data range is not part of the data type. Therefore, type definitions for numeric controls do not define the data range for the instances of the type definitions. Also, because the item names in ring controls do not define the data type, changes to ring control item names in a type definition do not change the item names in instances of the type definition. However, if you change the item names in the type definition for an enumerated type control, the instances update because the item names are part of the data type. An instance of a type definition can have its own unique label, description, default value, size, color, or style of control or indicator, such as a knob instead of a slide.
If you change the data type in a type definition, LabVIEW converts the old default value in instances of the type definition to the new data type, if possible. LabVIEW cannot preserve the instance default value if the data type changes to an incompatible type, such as replacing a numeric control or indicator with a string control or indicator. When the data type of a type definition changes to a data type incompatible with the previous type definition, LabVIEW sets the default value of instances to the default value for the new data type. For example, if you change a type definition from a numeric to a string type, LabVIEW replaces any default values associated with the old numeric data type with empty strings.
Strict Type Definitions
A strict type definition forces everything about an instance to be identical to the strict type definition, except the label, description, and default value. As with type definitions, the data type of a strict type definition remains the same everywhere you use the strict type definition. Strict type definitions also define other values, such as range checking on numeric controls and the item names in ring controls. The only VI Server properties available for strict type definitions are those that affect the appearance of the control or indicator, such as Visible, Disabled, Key Focus, Blinking, Position, and Bounds.
You cannot prevent an instance of a strict type definition from automatically updating unless you remove the link between the instance and the strict type definition.
