Export to jpg - limit file size vs resize to fit - best option or same?

Hi,
Sorry if this has been asked before, I take a large number of event images and the usual client request for images being sent to the press is image size rather than resolution, dimensions or other requirements.
Clearly in LR3 if the client has requested 3MB jpg the easy option is to after processing take my Canon 5d mkii RAW file and just hit export to max 3MB jpg.
My question is is it better - ie image quality better - to export by resizing longest edge to approx 3000 px and exporting to jpg which results in a similar file size, though different pixel dimensions? Or are they effectively the same?
Any thoughts?
Many thanks in advance on best practice....
Cheers,
dxbluey

To tell you the truth, a client asking for a 3MB JPG is a very meaningless thing to do.
Any time you are changing the number of pixels on a side, you are changing the image quality. Any time you are forcing the photo to be a certain size in MB other than the maximum, you are accepting a certain reduction in image quality. Which is worse? It all depends on the original, and how much change you are asking for.
So, that's my answer ... IT ALL DEPENDS.

Errors when using "Limit file size to" when exporting images

When I try to use the "limit file size to" option in Export, I often get at least one image that doesn't export, and I get a dialogie box like the image attached here:
As I am exporting in batches, it geats really messy and risky too!I have tried various file size options but that doesn't seem to be a factor.
Any ideas on solving this, or is it an unfixed Lr bug?!
thanks in advance

I can't reproduce it here, so you could try trashing the preferences file http://members.lightroomqueen.com/index.php?/Knowledgebase/Article/View/1148/198/how-do-i- delete-the-lightroom-preferences-file
If that doesn't do the trick, post it on the Official Feature Request/Bug Report Forum

Export Options_Automatic Stacking and File Size control

There is a big hang-up in work flow, and I'd assume it's the same for many professional photographers.
It would be great to be able to Export an edited photo (tiff, psd, jpg, RAW), and during the export be able to specify maximum file size (as you can control in Photoshop's Save to Web command), and then also be able to have Lighroom automatically stack the exported image with the original.
This is a big hang-up when you're finished editing multiple sized copies due to different media, and then you have the final web-sized image for your photo gallery. CUrrently, I have to go to Save to Web in Photoshop, and then save it to my desktop. Then I have to manually import that compressed jpg into Lightroom, and put it into the original library or collection.

Yes, the ability to export to a given file size would be awesome for those of us who post many images to the web.
Also, being able to export and automatically add the exported file to my catalogue (Same as when you edit in PS) stacked with the original, would really aid my workflow.

Export to PDF (smallest file size) is giving me a very large file

Hi all,
I got 2 document with around 100 pages (same size), with a picture or two in each page.
I've been using the Export to PDF (smallest file size) and export it.
first file became 5MB, which is fine
second file became 30MB, this is much too much.
I have used the exact same setting for both files and have no idea why the big difference between them.
The only difference between them is that first file contains CMYK photos, and second one - RGB.
Can this be the difference?
Any suggestions?
thanks,
shlomit

That's certainly part of the difference. Additional font information if one of the documents uses more fonts or additional glyphs could be some of it, too. Swatches and styles might also be a factor. Vectors don't compress like bitmaps, either.
Have you opened the optimizer and done a space usage audit to see what is taking up all the space? Did you do a Save AS before export?

Final Cut Pro exporting Quicktime movie and file size

I make short stop motion animations in FCP and usually when I export using current setting the file size is about 230MB for 60 seconds movie. However with the current project the exported quicktime movie file is only 32.1MB for 57 seconds movie. I don't think this is normal even though I set it with "current setting" and check off the make movie self-contained box.
How could I make the export setting back to normal so the exported quicktime movie will still be in high quality in a big file size?

Hi Ian,
it looks clear and same quality as usual. Maybe this is just how it is.
I am still worried because I exported another project to test and this one also is now exported into reduced file size. This is a 60 seconds movie and when I last exported, FCP created a 225.2MB quicktime file and when I exported exactly the same project again just now it is only 22MB... again, this is not self-contained movies.
To be honest with you I am really not familiar with digital settings, and I was trying to figure out export setting for a required file size and aspect ratio etc. for a projection the other day and it has been since then that my FCP started exporting smaller size QT files.
My project is in 4:3 ratio and all images on video sequence are digital still images. If you could kindly point out some places to look at to make sure that the settings are correct, that might be helpful (?)
thanks much!

hi,

*I found where to set the bit rate and it solved the problem. (the default

Now it takes same space and the quality is the same as the original.

How to restrict users from uploading malicious files(exe, dll,etc) & limit file size in a webform

Hello, please i have a file atachment field in a form on my site. I want to restrict the size of the file that can be uploaded and the type. It's a vacancy page and I want candidates to only upload doc and pdf files. I want to also limit the file size to 50mb only. How can this be done within the BC system.
Thanks.

The file extension can't be trusted, like the mime-type it can be faked by a malicious user. Also this method can just be avoided altogether by anyone who has javacript turned off. Using javascript for this is not even remotely secure.
Isn't there a way to allow file uploading but specify a whitelist of filetypes (preferably checked using byte headers or some effective method) somewhere in admin?

Hey there,
You can do the file extension with jquery for example. The basic aspect of that is:
var ext = $('#my_file_field').val().split('.').pop().toLowerCase();
if($.inArray(ext, ['exe','dll','jpg','jpeg']) == -1) {
alert('invalid extension!');
So what is hapepning there is that it checks the value of the field when someone has added the file and checks the file extensiona and produces an alert but you can do as you need.
You could run this on hover of the submit button, on change of the actual file attachement field or on click of the submit button in the checks before it submits.
BC limits files to 100mb anyway so you should be ok on that front, they wont be able to be crazy uploading.

Problem exporting image to specific file size

I've had some professional images shot and I can see from the file size in Aperture that they range from 13 - 73 mb. I need to submit them as 72dpi and 300dpi files and they must be between 1 & 3 mb in size.
I'm having no problems in exporting them at the correct dpi but the file sizes come out between 451kb and 1.8kb: 3 of the 6 images are too small, ie under 1mb.
What I'm doing is 'export version', then choosing the preset option of 'jpeg original size', editing it to the dpi I want, setting the image quality at a max of 12.
How can I get these file sizes to be bigger?
Thanks, and please help me quickly because I've a submission deadline approaching!

Well that's interesting Ernie. I did as you said, but also exported an image while I had the settings at 4288 x 4288 pixels. The resultant file size at that setting is 1.4MB. The file size when I went back to 'original size' is 795KB, exactly the same as before.
So I thought - if I can go above original size in that way, then can I alter the % to be over 100? I tried at 150%, which it accepted, and I've now got a file size of 1.3MB.
So I guess I've got what I wanted - not that I really understand it, because 'original size' clearly isn't original size at all!
Sorry Leonie - I didn't answer your question - they haven't given me a specification for pixel size as in 4288 x 4288: only 300 & 72dpi, a file size of 1-3MB, and a they must be JPGs.
And thanks for your help Frank - I've tried starting out with JPGs and with TIFFs as the photographer supplied me with both. I'd cropped some of the images but not others. I appreciate you offer of having a go with my images, but I think that - as I can go to over 100% - I've got it sorted now! Just hope there's no deterioration in image quality.
Many thanks everyone!

What's the best settings to Export movie for smaller file sizes?

Hi, I've been working on some helmet cam footage which was taken with Xvidmpeg4.avi and was advised to convert it to dvavi for editing in PrE, this created a huge file to work with, the original footage was 206mb and the finished edited dvavi file is now 1.56gb, what settings can I use to export the movie with a much smaller file size, but hopefully try to retain some quality, to upload to places like Vimeo? I thought I would try to export it in the same as the original footage Xvidmpeg4.avi thinking this might compress it again to something like the 206mb of the original and the original was good quality footage, but PrE just hangs up with a box stating 'Xvid Status (Not Responding)' and when I try to cancel that the whole thing crashes and closes? So when I go to File > Export > Movie, what would be the best settings in:
General > File Type ?
Video > Compressor
lots of options under compressor if I select the file type as Microsoft AVI, so I'm guessing something under that would compress it to a smaller file size but what, I could spend all night trying different settings so hoping for some advice?
Or, if I'm completely in the wrong place for the settings and should be doing something else please tell me?
Thanks, Gav

Thanks for the replies, but to me it's still confusing - simply because there are so many settings, if I go to Share/Personal Computer I'm then presented with a whole load of settings
NTSC Flash Video
MPEG
DVAVI
Windows Media
QuickTime
and under each of those is a lot more advanced settings?
I'm guessing I wouldn't use flash or quicktime, so which of the others would I use and what are the advanced settings to use as I can't find anything that is .wmv or .mov
What I've done with other videos that I've exported from PrE as dvavi is then to put it through Windows Movie Maker, Publish Movie, This Computer, then put the settings to Windows Media DVD Quality (PAL) (3.0 Mps) - this seemed to be the only setting that reduced the file size considerably but still had good quality, but it's still about twice the original file size?
This all seems long winded to me, open original file, convert original file, output another file, then output the file again in something else which then results in loss of quality and a larger file than the original? I'm ending up with lots of files, was hoping just to edit in Premiere then export/publish that edited clip and that would be it, then upload to the net.
Is it not possible to just edit my original footage and save it, just like you would with something like a word document, should I be using something else and not Premiere?
Thanks.

How to limit file size for FileUpload UI element?

Hi all,
I'm using the FileUpload UI element in NW2004s SP20.
I want to limit the size of the uploaded file.
The simple option is to load the file to the context, check the size, by using
InputStream stream = resource.read(false);
double size = stream.available();
and report errors if any.
However, I don't want to store huge files in the context or flie system (even temporarily) nor 'spend' network resources for uploading a file that I won't be use...
Is there a way to limit the file size by using some property for the fileUpload UI element in the server?
Is there a way to check the file size before it's uploaded (for example like GMAIL does - checks the file BEFORE the actual upload)
Regards,
Omri

Hi Omri,
"(but this can be checked AFTER the file was uploaded)" - what do you really mean here? I mean your main query is to restrict the file upload if it crosses certain size-limit. What is the use if you check the size after upload?
My problem is the network traffic and the CPU load if users are trying to download huge files..., if the upload is restricted for size this download problem will not come .. correct?
Not sure about the UI element properties has something to restrict the size, and if its really related to Network traffic and CPU utilization, i think you've to check with Basis team to re-sizing the servers to meet this new requirement of upload/download if its not considered before.
Or the last option i could see is to use KM Upload iView if sizing is done with these considerations.
Thanks,
MS

Exporting to iDVD - Max file size - Shorter bounce time

I put in markers on an iMovie project that I did in GarageBand 08. After I put the chapter markers in, I went to export to iDVD but keep getting error message "Maximum file size of 2 GB exceeded. Please choose a shorter bounce time. However, the GarageBand version of the project is only 1.18 GB. I tried to compact it down but it gives the same error message.
I tried finding out what is meant by bounce time and how to shorten it but the online manuals don't mention it at all. I've used the chapter markers before in GarageBand and I've never had this error message before.

Don't know if you ever found a solution to this… I just ran across the same identical problem. In searching the web I found this discussion which seems to be working for me. It involves disabling an advanced preference in iDvd.

QuickTimePro - Export vs Save - Different File sizes

Hi,
with the trim to selection command I selected a bigger part of an AVI-video (Video track format: MPEG-4 DivX v.5 + Audio: Mpeg-1 layer 3 (mp3)).
Although I did not change the video or audio settings I got different file sizes:
The exported video has double the size than the saved file.
Therfore my questions:
What is the reason?
What should I prefer - export or save - trying to get smaller files with the same quality?
Thanks for a tip.Greetings from the heart of Germany
Herbert

HI mrfibuli
I think you are seeing a general housecleaning of things that
were formerly in your library. For example, lets say you took a
fairly large project. Perhaps 80 slides. Then you delete 60 slides.
This would leave many items in the library. They would be there,
but be unused. So you save as, and after a couple of times of doing
this, the unused objects are purged from the file. This is why you
are seeing a difference in size.
Sincerely... Rick

How to export in a small file size in FCP7 ?

Hi,
I'm filming with a GoPro camera on 720p 60fps.
resulting files are MP4 files wich I convert to Apple ProRes files.
Now when I want to export my movie, it has a VERY big file size..!
Can anyone tell me how to export my movie in a smaller file size.
It doesn't has to be the smallest file size, just small enough so I can upload it on the internet etc.
Thanks very much,
Yannick.

Export a reference video (command-E, current settings and "self-contained" should not be marked.
Then import to compressor, use one of the h.264 settings... Start with the LAN setting and go from there.

How to limit file size in LR for photomerge in PS5

Is there a simple way to limit the file size of the photos selected in LR3 for a photomerge in PS5?
I have found that without limiting the size, the panoramas generated are very large - 1GB or greater.
I've found an work around by opening the photos in Bridge and then in Camera Raw where I can reduce the file size before using PS5 for photomerge. After I've done this, it's a bit of a hassle to get the panorama back into LR3. The benefit of this approach is that it speeds up the processing significantly and helps downstream with any subsequent processing since the files are just large and not ginormus.
If this isn't possible, this seems like a good idea for LR4.
Thanks, Chris

A tip of mine that Martin Eveing includes in his Lr2 and Lr3 books is as follows:
1. In Lr, selct the images you wnat to included in pano
2. From Edit in Ps menu choose "Open as Layers". The images will all open as layers in CS5
3. In CS5 choose Image Size from Edit menu and downsize images
4. In CS5 choose Select all Layers (Cmd+Option+A or Ctrl+Alt+A)
5. In CS5 Edit menu choose Auto Align.
The rest of the process should be self explantory

Pshop CC -- saving JPG & PNG file size bloat

Saving JPGs & PNGs from Photoshop CC is creating what I can only describe as a obscene file bloat. Just recently, what should have been a 7k jpg saved as a 1.1 mb jpg file. PNGs which should average roughly 100-150k are coming out at 1.3mb. If I use the "Save for Web", sometimes it gives me the proper sized images.
I have noticed this on 2 computers --- one a mac & one windows with completely different file sets. So it is not an issue of my OS, the original files or anything specific to one particular common item.
FYI -- Doing the same thing with pshop cs6, I get the proper file sizes.
I have included a sample image here. This image is a straight out "save" from pshop CC -- it is 1.1mb. However, when I saved the same image as a JPG in pshop cs6, it was 7k.
Is anyone else experiencing this issue?

Haven't had a PNG or JPG go wacky here in that way so far...
I think the issue is revealed by looking in File - File Info in the Raw Data section. I don't know why, but there are a huge number of <rdf:li> XML elements showing up there with hex values in them. I don't know what that means, exactly, but I believe the accumulation of that metadata explains the size increase.
Do any of the terms you see in the raw metadata mean anything to you? Do you have 3rd party plug-ins that could be responsible for this?
