Selecting "Use Previews" when exporting?

Hello, everyone. Can someone please explain to me the benefit of choosing "Use Previews" when exporting? Does it increase the quality of the final render? If so, what are the comparative values of additional time versus additional quality? Thanks, Brum

Theoretically, it will decrease the quality, as what this command is specifying is that the exporter should use the files you already rendered in Premiere. Depending on the preview codec that is used, you will be recompressing a file that has already been recompressed. The benefit is that the export will be faster, because the video frames don't have to be processed before going to the final compression. Of course, this is sort of a wash, as you have to account for the time that preview rendering ate up.
For quick exports where you might have already rendered a timeline (like for a quick one-off to send to a client), you can tick the Use Previews box, but my feeling is that in real world practice, you typically don't want to use this.

Premiere Pro CC not using previews on export

I'm using PP CC on a decked out iMac(i7, 32Gb RAM, 14TB RAID, internal SSD) and my exports are very slow even when "use previews" is checked. Thing is, I don't think PP is using those previews. During the export I can see that aerendercore and importerREDserver are running. The sequence is already rendered so it shouldn't be pulling in the raw files from the red server or going to AE to render the linked ae comps. Right?

I've been through this discussion before ... talk about deja vu all over again!
The best explanation I have received was at NAB, with two of the heavy-lifter behind-the-scenes staff of Adobe's video programs. Long and involved discussion, one of those where for about the next ten minutes I felt very enlightened on video processing, codecs, and computer hardware design & usage. And then reverted to a normal human status over the next hour. Ah well.
Basically, there's only a couple 'codecs' where it is even possible to utilize previews in a render-out full export. They're huge puppies and most of us don't have the massive-capable machines that can handle that stuff on the fly for editing purposes. As to the rest ... remember, PrPro is like Lightroom, NOT Photoshop. It never makes a complete new 'file' when 'saved' like say Photoshop does, but only stores the info of the changes you have called for to be applied to the original footage, similar to Lightroom. And note, just as Lightroom can create p-views of various sizes up to 1-1, it never utilizes those highly-compressed p-views when you want to create or "export" a final form of the image for use. It takes the recipe of what you've ordered done to the original image and creates a version of that image with that look in the size and file-format (think codec) of your choosing. Which has nothing to do with the file-format (codec) of the internal-use p-view, even a 1-1 p-view.
When viewing a monitor during PrPro, Sg, & AeFx, that's what you're seeing: the original footage with your changes added to it on the fly ... for the most part. In all three programs there are things complex enough that it will create new viewable bits & pieces but in very few situations will it ever completely create a new run of footage. You'd howl if it did ... think of the massive increase of stuff on your drives if it behaved that way! The bits it stores as "Previews" are neither complete new forms of your original footage nor are they of the quality you'd want or the particular nature of pixel-structure for any specific codec you want an output prepared into.
When you render sections, or even entire clips/sequences for previews it renders those frames and sections of frames that are problematic into an internally-chosen codec that is quick for it to use on the fly and looks ok, and constantly intermixes those bits with original frame and the 'recipe' of what is being called for. It does NOT make an entirely new & complete form of the original footage with all changes applied.
Apparently, there has been discussion internally as to whether the "Use previews for export" button should simply disappear unless you are using one of about two video formats that actually "live" in PrPro as full-res/size files. I asked why this hadn't been done, and the response was ... it's been considered. It would save a lot of hassle, grief, and arguments if they did, is what I'm thinking. The vast majority of us don't have one of those rigs that's like four super-Macs built into one "single" computer. Or a mobo with 8 different quad-or-better core cpu's, that sort of thing. We're not working directly in the formats that need such hardware.

Can I use preview to export multiple page PDF as jpegs?

Using Preview, I export multiple page PDF as jpeg and results are the first page only as jpeg. Can I use preview to export multiple page PDF as jpeg for every page?

Automator is great for this if you need to export many pages to JPG, or just have to do this often.
Two other quick and dirty way sto get it done:
(1) Enable thumbnail view, click on the ONE PAGE you want to convert to jpg, then choose "export." If you choose more than one page, only the first will get exported to jpg.
(2) Create a copy of the file, delete all the pages except the one you want to export to JPG, and export that page. You may be able to "undo" the delete, get all your pages back again, and re-delete all but the one you want to export, etc. I would not recommend doing this on the original version of the file because of Preview's autosave so-called "feature."

Using Preview when printing from SAP

Just starting to use SAP Java GUI on the Mac and one of the 1st items I discovered was the inflexibility for printing. I would need to define the printer in the preferences of the SAP Java GUI and then anytime I would print it would just go to that printer.
Problem with this is that sometimes I work from within the office, and sometimes from home with as a result that my printer changes.
When on Windows, I also often performed a print from within SAP but then selected the Adobe PDF printer instead so that I had a resulting PDF file.
What I thus really wanted was for anytime I print from SAPGUI to the local printer to get a print dialog just like it does on Windows. I checked around but could not find anything to replace the lp command with on Mac that would then provide this. As a work-around I developed the following small script instead. Now instead of just printing, the print-out will be shown in Preview as a PDF. From here I can then save it as a PDF, print it, mail it, .... anything else one can do with Preview.
This is not the exact solution I wanted as I wanted to just get a print dialog; but this gets me a lot closer to it.
See next post (hopefully as I am having issues posting) for script & steps.

Instructions:
First, make sure that printing is setup for SAP Java GUI. There is sufficient information out there but main items are that the printer within SAP is defined with method G and that the device type os POST2 (for postscript). Also ensure that under output attributes Color printer is checked.
Next create the script. I put it in the /Applications/SAP Clients folder but it can be put anywhere you like. You can name the script however you like, I named it SAPLPD.
First thing the script does is converting the postscript file to PDF and storing it in the user's temporary directory. It adds the timestamp to the filename just to ensure there are no duplicated. It then opens the PDF file using Preview. It will wait for 1 second after which it will remove the file created.
It also looks that all the files in this temporary directory are automatically removed by OSX, so even should the file not have been removed; on next logout (I think) the file will be removed anyhow.
Script:
The script is:
#!/bin/bash
timestmp=`date +%Y%m%d%H%M%S`
/usr/bin/pstopdf -i -o $TMPDIR/sap_print_$timestmp_$$.pdf
open -a /Applications/Preview.app $TMPDIR/sap_print_$timestmp_$$.pdf
sleep 1
rm $TMPDIR/sap_print_$timestmp_$$.pdf
Once you have created the script it needs to be made executable. Do this by open the Terminal, changing to the location where you saved the script and entering the command:
chmod a+x (script name)
So in my case I would have entered the following 2 commands in Terminal:
cd "/Application/SAP Clients"
chmod a+x SAPLPD
Last but not least is changing the command the SAP Java GUI uses for printing. Go into preferences for the SAP Java GUI and go to the Printing section (under Desktop). There for the Print Spooler entry which is currently set to /usr/bin/lp you change that to the script. So for me I have:
/Applications/SAP Clients/SAPLPD
Easiest way to do this is by using the Browse button and then going to where the script is. No parameters are passed to the script so everything else can be removed. What I have is exactly what I show a few lines above.
And that is it, when now printing from SAP it opens the print-out in Preview and from there I can select my printer options etc.
Use of the script is on your own risk. It works for me but there is no guarantee that it will work for you.
Would love to hear about any other options.

It´s not possible to use compressor when exporting to compressor 4.0.7 from FCP 10.1

It is not possible to work with Compressor 4.0.7 from a Project send fro FCPx 10.1
I did not upgrade compressor to the last because it does not give the possibilities of version 4.0.7
Any suggestions?Thanks

Yes. Export a master file from FCP and bring that exported file into Compressor's source file well.

"Use Preview Files" works in CS5.5 but is "Useless" in CS6

I'm a heavy user of the "Use Previews Files" option when exporting files. This has worked great with Premiere CS5.5 but using the same method in CS6 no longer works and reverts back to rerendering the original files in the timeline and rerendering all the effects on them which is very time consuming since the original files are HD and are being downscaled in a DV widescreen timeline.
Anyone figure out how to get Premiere CS6 to correctly find the preview files when exporting using the "Use Preview Files" option?
In the meantime, I had to load all the preview files I had rendered back into a new timeline and reassemble them in the correct order. Once I did that, I exported this 1 hour 38 minute timeline to an MPEG-2 file which only took 19 minutes instead of the 7 hours it would have taken even with the "Use Preview Files" on and with a fully rendered timeline.
Again, it works great in CS5.5 so something changed in CS6 to make the "Use Preview Files" useless now.
Randy

OK, decided to do a simple project and test the preview files. One HD AVCHD video clip, 24 minutes long. Dropped into a DV widescreen project and the video clip downscaled to match the project. Added a color correction filter, Shadow/Highlight filter and Sharpen filter. Cut the clip into 4 pieces and adjusted the color correction on each. This will generate 4 preview files. This is basically what my larger project involve but with many more video clips.
Did not render timeline or make any preview files then exported an MPEG-2 file. Took 35 minutes.
Rendered timeline which produced 4 preview files in the DV AVI format. Took 1 hour.
Exported an MPEG-2 file again but this time selected "Use Preview Files". Took 35 minutes.
Exported a DV AVI file (same format as the Preview files) but this time selected "Use Preview Files". Took 35 minutes.
Imported the 4 DV AVI preview files and put into a new sequence. Exported an MPEG-2 file using no preview files. Took 3 minutes.
Imported the 4 DV AVI preview files and put into a new sequence. Exported a DV AVI file using no preview files. Took 1 minute 30 seconds.

IRS Form 941 un-fillable line using Preview

There is one line item on the January 2007 version of the fill-in IRS Form 941 that I cannot select and fill-in information using Preview 3.0.8 (409): "Name (not your trade name)". With every other item on the form, I can tab or mouse into, but not this one. Is this a known bug affecting more than me? Is there a fix?
MacBook Pro 2.33 GHz 2GB RAM Mac OS X (10.4.8)
PB G4 1.25GHz Mac OS X (10.3.9)

Thanks for pointing out the issue with this form. I checked it out in Reader 8 and in Acrobat 8 and it worked fine (just like you said). I also opened it in Preview and it had the same problem as you mentioned. I opened the file in Acrobat and looked at the properties of the field, and could not find a reason for it.
I did all this because I work at the IRS in the Forms area - specializing in fillable PDFs - and we take any problem with our forms seriously. You can let us know about problems with our forms by using the "Contact Us" part of the www.irs.gov website. If you leave your email, they will reply back to you.
I will pull the form apart and see if there is anything under the covers that might be causing this, but at first glance, I could not find anything.
We do not recommend using Preview when interacting with IRS forms though. You get more consistent results with Adobe Acrobat or Reader. And the form is saveable using Reader.
I will let you know what I find out.

Using preview files from Pr 5.5

I use the Suite 5.5 and this question is about Encore when using the Dynamic link from Premier Pro (Pr). I have always used the automated way to import from Pr to Encore. It automatically compresses as needed to fill the DVD. And because my video is almost always under 2 hours that works great. Even for videos that are over 2 hours long. Now here is the problem:
Sometime I use several effects in [Pr] and render so I can better see what I am doing without all that skipping.
I would like to use the render files (previews) for making the DVD in Encore when transcoding.
Yes, I understand you go to Edit Quality Presets and at the bottom you checkmark the [Use Previews] box. But now it is nolonger automatically compressing the file to fit the DVD, or I don't it so.
So the question is:
How can I use the preview files (rendered files) from [Pr] to speed up the transcoding in Encore and automatically size fit the Video to fill the DVD.
Thank you,
Tom

I don't think you can get both aspects - automatic or use previews.
The settings for a dynamic link transcode are in Encore. When a preset is selected, "use previews" is not selected by default, but can be selected by customizing the preset. But you have no control over the settings used for the automatic setting, beyond the default transcode setting, which for DVD is basically the max bitrate.
A "bit" of bitrate calculation and you'll still be good to go.

Always Use Artboard to Export (CS5)

In adobe Illustrator CS5 —
Is there a way to always Use Artboards when exporting to JPG...etc? — instead of having to click the check box every time?
Actions don't work because they save the path that was last used — I just want to simply be able to export all artboards, all the time.

Asked around at work. One solution is to use File --> "Save for Web" as PNG-24 instead of using the "Export" function.

I created a brochure in pages and exported it to a pdf format. The pdf looks and opens perfectly using preview but when opened in adobe reader (which my printer uses), fonts look odd, transparencies don't display...etc. Tells me error exists on page?

I created a brochure in pages and exported it to a pdf format. The pdf looks and opens perfectly using preview but when opened in adobe reader (which my printer uses), fonts look odd, transparencies don't display...etc. Tells me error exists on page?

Does this essentially mean there is no way to fix this problem on my end? It's a pity because the design and branding of my brochure will suffer if I remove transparencies and use different fonts. It also concerns me moving forward because it means the quality of print on my pieces will be significantly lower because most commercial printers use Adobe products.

Hi there! So I am using Lightroom 3 on a pc and I have ran into an issue when exporting images. The DPI and image size (in inches) that I am selecting during the export process. For example I just exported a collection and set the dpi to 180 and the size

Hi there! So I am using Lightroom 3 on a pc and I have ran into an issue when exporting images. The DPI and image size (in inches) that I am selecting during the export process. For example I just exported a collection and set the dpi to 180 and the size to 7 inches on the long edge. My exported result is 457 dpi and sized at 3200x2134 pixels.. Any ideas on why this is happening and what I can do to correct it?

The DPI setting in a digital image has no meaning at all. You need to learn how to calculate what you need in your exported image. The only measurement in a digital image that has any meaning is the number of pixels in each direction. It doesn't matter what you set that DPI to (actually it's PPI or pixels per inch). The image will have the same number of pixels regardless of the setting. If you need an image that is 5 x 7" (for example) at 200 PPI then you would want an image that measured:
5 x 200 = 1000 pixels
7 x 200 = 1400 pixels
So you would need an image that is 1000 x 1400 pixels to have a 5 x 7" image at 200 PPI. The reason your exported image had such a high PPI setting is because you specified the number of inches you wanted the image to be. And there were enough pixels in the image that it calculated out to be that high PPI setting.
I apologize, I don't explain this very well. But you need to learn to do the math to determine how large you really want your exported images to be.

LR 4 on Windows 8 - Cannot create preview thumbnail when exporting?

I thought I had this figured out but it appears to occur somewhat randomly. Since upgrading to Windows 8 when I export files that I have imported from Canon raw .CR2 for some files it gives an error that "the file could not be written" and lists the original source .CR2 file name. It does not do it everytime but once it happens it happens everytime for that file. When exporting 10 JPG files for example only 3 of them may have this issue. The file still exports and creates the JPG file and the only issue with the exported file appears to be that it did not create the preview thumbnail.
I have tried importing the files into new catalogs, writing to different folders etc but it still happens. Any ideas?

Ok, after lots of attempts to recreate I can do it like this:
Export as JPG to hard drive and select 'limit file size' option and give any size smaller than the full 100% quality JPG would normally create. Using any other options to limit file size such as quality < 100 or resize long edge to 1024 completes successfully.
Can someone else confirm this on Windows 8 with LR 4.2, it only takes a single file?

Can I use applescript to export PDF search results from "preview"?

My question is about "Preview". I have a very large PDF document that I am using preview to view. After doing a search for a specific word, preview has returned 1200 results. The results panel shows the page number the result is found on and the line of text on which the searched-for-word is found.
My question is this: Is there a way to export this information from preview to something like an excel file? The end result would look like a table with two columns. One with the page numbers and one with the line of text in which the word appears.
Is this something that can be done with applescript? I don't know if the system even stores that kind of information... /sigh. Any help is appreciated.

Using Preview.app, I have done a search for the word “AppleScript” in the PDF version of the AppleScript Language Guide. Then, I have used the following script to retrieve the information displayed in the results panel.
tell application "Preview" to activate
tell application "System Events" to tell process "Preview"
return value of text field 1 of rows of outline 1 of scroll area 2 of splitter group 1 of window 1
end tell

Preview is broken and when exported in Nik Software plugin, it's black or over bright

I'm working on a project for a Sail championship (last month the J24 European Championship, while this week Interlaghi) and since I started the last one I've really great problems with preview and "exporting" in Nik Software, that I never had before.
This is workflow:
shot image in raw (Canon eos500d)
import image in Aperture3 (images are refered on external drive normally, but now for this project are refered on the desk, I've an 256[GB] SSD with 8[GB] of RAM)
edit the image with Aperture3 controls, if I'm not lucky leaving the full screen the preview (big) dissapear and broken (small)
if I'm lucky open the image in Nik Software (e.g. Dfine) and work on it, when finished if unlucky back to point 3
if not luck the image in Nik Software is Black
so regenerate preview, and similar action are taken (last night I've also rbuilt all archive, with cmd+alt click aperture icon)
if luck I can work and export
if not luck I must close Aperture and keep crossed fingers.
At the begining I thought it could be a problem of too many images in the same folder and aperture-project (1800), but this is not the first time I work with big volume (airplanes shooting in Axalp normally is 1200 shots in one day).
I thought even a speed problem on the archive (the externa HD is 5200rpm on FireWire).
So I decided to relocate raw files on the desk, as I said I've a 256[GB] SSD; but nothing change!
Maybe a problem on TIFF export??
Someone can tell me a solution? the only big change in my usual workflow is that now there is Analog Efex Pro (that I don't use).
extra: I'm using a MacBook Pro (after june 2009 version 5,5 )
Here I post some screenshots:

Update!!!
I just discovered, that the problem is generated by Aperture3 bug: when I go on some image it change setting of CURVE and/or LEVEL
