Loss of image quality in file transfer

We shot an event live and have no problems broadcasting the recorded MPEG file from our Nexus. However, when I try to transfer the file into Premiere Pro or Encore to author a DVD the image is severely pixilated and the quality is unacceptable. The video was shot in Standard DV-NTSC . I have gone over my project and sequence settings a hundred times in PP and Encore. If I drop the MPEG file directly into Encore the image quality is a little better, but still not as good as what's on TV. We think it might be a codec issue. Any suggestions? Should I try this Gspot program?

Yes thank you lets focus on Encore. I am using CS4, and it is an MPEG-2 file if that makes a difference. I ran the file through Gspot and noticed there were like 20 something codecs that were listed as having a "problem"; mostly Ulead and MainConcept[Adobe2]. As far as preview, monitor, and test burn... it looks bad in all three.

Loss of image quality after rotate canvas

PS7 on Win XP
Windows Explorer and some software bundled with digital cameras [Canon and Panasonic] warn when rotating a picture that there may be loss of image quality. Presumably it must re-compress the jpg image file?
In order to avoid that problem, I have been rotating image files in PS7, since no such warning comes up there.
Is there loss of image quality by rotating or cropping in PS7? I usually save jpg files at quality level 10.
TIA

Reduce image quality (and file size)

Is there a simple way to reduce the quality of all backgroung
images ? (there are all bitmap images, about 3 MB each of them)
I imagine that by reducing the image quality, the file size
will be less huge...
But I wasn't able to find a way to do that...
(the option about JPEG quality in project/preferences has no
effect, because all background images are bitmap... )
Any idea is welcome !
Valérie

Hi Valerie
I have been doing some research on this -- the issue of file
size (relating to both .cp and .swf) crops up a lot on this forum,
so I wanted to find out which were the critical factors relating to
images.
My findings show that there are two critical factors:
-- Slide Properties: Quality (High, Standard, JPEG,
Optimized)
-- Format of original image file (used for slide background
or inserted image object)
To summarize the results of my testing:
Slide Quality
Changing the slide quality from High
to Standard or JPEG makes little or no difference to the size of
the .cp file but can *significantly* reduce the size of the
.swf
This is an especially useful way of
dealing with the very large .swf file sizes caused by importing PPT
slides
A .swf consisting entirely of
imported PPT slides with complex backgrounds may be reduced to less
than 10% of its original size by changing the quality setting for
each of the slides to JPEG and using a JPEG image quality setting
of 75%.
Format of original image file
For complex images such as photos,
the best image file format to use is (oddly) .bmp -- although it
results in a larger .cp file than other file formats (such as .jpg
or .png), it generates the smallest .swf output.
The benefit of using the .bmp format
is less marked if you have set slide quality to Standard instead of
High, but it can still cut the file size of the .swf output by up
to 50%
For slides using a quality setting of
JPEG, there appears to be no difference in resulting .swf file size
between .bmp or any other image file format
A final comment: it is interesting to compare the size of the
.cp and resulting .swf for different Captivate projects. There is
typically an assumption that the .swf file will be smaller due to
compression. However, this is not always the case. For example, I
tested one project that used High slide quality and images that had
been inserted from .jpg files -- the generated .swf file was over 4
times larger than the .cp file. However, when I changed the quality
setting for all slides to JPEG, the .swf file reduced to less than
50% of the size of the .cp file.
I hope this information is helpful -- please contact me if
you'd like to see the detailed test data.
Best regards,

InDesign Transparency Effects - Problems with Image Quality and File Size

Hello,
We are experiencing new problems exporting InDesign files to PDF.
To summarize, though our largest workflow is to create files for offset printing, we also deliver our work to PDF for mounting on a website so our clients can download directly from the web. Our new problem is Transparency Effects, and creating a PDF that will both have a high quality (or resolution), and be a small file size.
We are working with multiple page documents (24 to 48 pages), and would very much like to work with InDesign Transparency Effects. However, after spending much time testing a variety of PDF types, we are finding there is a radical difference between quality and file size. I was curious if anyone has had these problems, and if there is a simple answer. InDesign is an incredible program that allows us to design on the fly with Transparency Effects, but, if we are going to experience these problems, we will have to eliminate these wonderful tools.
Can you help me or lead me to information online that will help.
Thank you,
Lain

Please don't post in multiple forums. Your question has nothing to do with the PDF language and specifications, but rather PDF workflow or InDesign. I've responded to your other posting and am closing this thread.

Loss of Image quality and shimmering in Imove

Hi. This is a posting very similar to another forum user but I have the same problem!. I am downloading images from a Pentax K10D onto the Book pro and they are fine, as soon as you load them into iMovie they are terrible, poor image quality, edges of what ever is inside the photo move with a shimmering affect. I have been to the macintosh shop where I live and they don't know!. I have put this on Mac help pages in the USA and Spain still now help or comments, surely someone must have an idea as to why this is going on or is it through bad design of software!!??. regards to all. Kevin

Hi Matti. Thanks for your work and help you are giving to me and others. I have printed off your info and will try and get my poor old brain round it!. So many people are having the same problem with iMovie it's amazing that the mac software dept has no don anything to rectify this bug and or problem. I have downloaded the software you state "Photo to Movie" but it does not seem to have the same things as iMovie with all the fancy transitions of images and music in the background, I have tried 4 images in this software and thay come up on full screen as 100% perfect, I still have to work out how to get them onto DVD with some kind of presentation. I want to start in the field of wedding photography and need some high end presentation software for digital wedding albums or Imaging with transitin affects, what would you recomend?. I am in spain so we are on PAL here, I think!. I have people over here in the Spanish Mac forums asking about the same problems, is it OK with you to translate some of yours and pass over to them in Spanish?. best regards. Kevin

Photo image size after file transfer much smaller

I am transfering photos over to my wife's Macbook and after the transfer, the photos are of a much smaller file size. Is there a way to transfer the photos at their full image size?

Dragging and dropping to a web-based email (gmail) makes the photo appear inside the message itself, and not as an attachment, which is what I wanted.

Loss of image quality and logo question

1. Finally able to publish my presentation to PDF, but even though HD video, there was significant graphic loss. Any thing that I did incorrectly? Is there a way to correct this or publish in another format ( internal company site) to improve this?
2. Is there a way to have the presentation start off with no Adobe Presenter displaying while waiting for the presentation to start or have my company logo display while starting?

Hi
About the video that you have inserted on the slide, I recommend not stretching the video on the slide
Letting the size of the video being the original as imported, will give you better quality video.
As for the logo, you can remove the logo and add your logo by doing the following
1. Create a new file named logo.swf of dimension 47 x 27 pixels that contains your branding.
2. Go to the templates folder under the Presenter 8 installation folder
3. Add your custom logo.swf file to the Templates folder.
4. In PowerPoint, publish the presentation to your computer.
5. View the output to see the new logo.
6. this logo will appear every time you publish any presentation
If you want to replace the logo in already published presentation
1. Create a new file named logo.swf of dimension 47 x 27 pixels that contains your branding.
2. Go to the publiahed folder >> data >> resources and paste the logo here
3. Go to the data folder and open vconfig.xml
4. Search for <uireplace name="logo" value=""/>
5. make value equal to "resources/logo.swf" and save vconfig.xml
6. Launch viewer.swf
The above mentioned steps replaces the adobe logo in the player.
If you want to replace the Adobe presenter logo in the loading screen
1. Open the published output folder
2. Open the vconfig.xml file in the data folder in Notepad. Search for <language id=”en”> section, and then look for <uitext name="ADOBE_PRESENTER" value="Insert Your Custom Text"/>
3. Replace the "Insert your custom text" with your company name
4. Save and close the vconfig.xml file.
5. Launch the published output
Hope this helps
Thanks

POOR image quality once files are in the sequence

I have been doing screen captures in Screen Flow and/or IshowU HD Pro to combine with DV NTSC footage in Final Cut Pro. First of all, all of the captured screen footage looks really bad when exported with compression unless it is exported lossless. Any attempt at compression seems to make a very poor fuzzy image. If I take a high quality lossless screen capture in to final cut it looks bad once it is in the sequence window. Specifically all writing that is small or any hard lines on the screen appear to be jaged, and generaly unreadable. Both screen capture programs (IshowU and Screen Flow) seem to work fine, I believe the prolem is within Final Cut, any ideas? Any help will be much appriciated.
Thank you,

sorry about the shout. thanks for the great feedback, you guys are awesome.
ok, so here is the info:
compressor: animation
frame size: 1440 x 900
frame rate: 29.97 fps
target: web dist. ... so will eventualy need to de-interlaced
monitor: canvas window (i think) i am viewing the footage on my laptop screen
The viewer/monitor is probably not the problem. I distributed a similar project on the web with the same problem. The video footage was excellent but the photoshop palettes were un readable.
It is being edited with footage from the GL1 (DV/DVCSpro/NTSC) which is 29.97 fps and a frame size of 720 x 480. The footage that we are having the problem with is footage that is captured from a screen capture program, we are trying to see pallets from photoshop clearly on a documentary/ tutorial.
When we view clips from the screen capture program in the final cut browser window they are perfect. But as soon as they go into the sequence (even after rendering or exporting) they look like poop . . The images look offset, like seeing double. Also a bit of colorfull digital noise, just in letters and lines that were black in the source footage.

IMovie 11 loosing image quality in still pictures

I shoot RAW photos with a Nikon D300 and import everything to Aperture 3 where I organize, correct and adjust.
I use iMovie to make slide show sequences - i.e. my daughter's third year - and have found that though the image quality is perfect in Aperture and in any file that I export, there is a loss of quality when the images are brought into iMovie. It is especially apparent in areas that have shadows or are dark - like the skin on an arm that is in a shadow while the rest of the person is in the sun. The shadowed skin looks like it's been pixilated -rather than a uniform transition of colors, it's blotchy.
I have tried importing the photos from the media browser in iMovie, I have tried dragging them from Aperture, and I have tried exporting them from Aperture to a folder and then importing them from that folder into iMovie. The results are the same - loss of image quality especially in dark areas of the photos. It doesn't matter if I leave it as Fit, Crop or Ken Burns - it's as if the base image information has been degraded for some reason.
The image quality degradation is clearly evident in the viewer - so it's not a matter of what the intended output / export / share option is or will be.
I have also found that this happens if I take a video file like a *.m4v file and import it into iMovie - wicked loss of image quality.
I also find that if I shoot video with my iPhone 4, and then download that into Aperture, I get a nice and crisp movie in Aperture. But when I try and pull up that same video in iMovie 11, again there is a loss of quality. This is especially apparent if I let it do image stabilization as it enlarges the frame a bit. Given that I have a really big monitor I can pull up the same video in Aperture that was not stabilized and moved to the same scene and resize side by side for a direct comparison - clear image degradation in iMovie 11.
As with the photos for slide shows, the bright areas don't seem to be affected, or if they are it's not as apparent - it's as if some setting is trying to automatically adjust the black point. But I don't know what would do this or how to stop it. Can't find such a setting anywhere.
Given that the system is a Mac Pro 2 x 2.8 GHz Quad-Core Intel Xenon with 14GB and two 1TB drives it's not, or should not be an issue of the system being overtaxed.
Hope someone knows how to fix this.

Image quality in iMovie

Hi guys,
I am trying to use iMovie to put together a slide show (I am a wildlife photographer) and it seems great for the job
There are a couple of bugs within iMovie itself but mostly no big deal, except for one that is bugging me.
The images I have generated are perfect quality when viewed in Adobe Lightroom, iPhoto or any other app, but in iMovie there appear to be far fewer colours so that (for example) the sky in an image is heavily pixelated. I can only guess there are fewer colours in the image.
I am confused because in one of the articles I read it claimed that iMovie was directly accessing the file on disk.
I simply dragged and dropped the hi-res images (they are all between 5 and 15 meg size) into iMovie.
Has anyone else come across this? How can I make the images in iMovie look proper so that I can export the

Are our events all co-mingled? Since ownership is ignored I assume we can see each other's video clips? This seems pretty messy to me and prevents any sort of privacy. In fact this basically breaks the whole user model.
Since still images are not stored as an event in iMovie '08, adding an image from iPhoto, your desktop, etc. adds a copy of the file to you project to serve as the "source" for later export of your project. In addition, since there is a maximum size associated with your project, this "stored" image may be scaled if the original height is greater than 1080 pixels. Therefore, my recommendation was to actually look at the "stored, scaled" file in your project so as to compare it with your original files to see there there was any loss in image quality. You can manually open the project "package" using the "contextual" menu option "Show Package Contents" at the Finder level.
I opened it in iMovie but can't see that option nor an option for setting colours to millions (which would probably solve my problem).
The ideal here is to open the file stored in your project and look at it in the QT Player for comparison with the original file. When I said "color depth should be millions," I was referring to the color depth you should find in the inspector window when you open the files in the QT player. Both should normally read "millions" unless you saved them otherwise.

IMovie 11 Slideshow image quality issue

Hi,
when I am creating a slideshow with iMovie from still images, I have a severe loss of image quality. I have tried to search forums up and down, but did not find any help or solution for that. The loss of quality is kind of dramatic. Any ideas, suggestions or solutions?

Loose image quality?

Hi, whenever I download pictures from my digital camera, they open in Preview. However, when I drag them to open in iPhoto, there seems to be a loss of image quality when the photo is registered in the iPhoto library...
Anyways to fix this?

Can you gie us some more information: Where are you seeing this "loss"
On import, all iPhoto does is copy the image - no more.
Are you accessing files in the Data folder of the iPhoto Library Folder?
If so, these are the thumbnails that iPhoto creates for display.

Image quality lost through editing with Photoshop?

I find a number of professionals using Lightroom as their primary photo editor.
I did a search on Lightroom vs Photoshop. I found the following listed as the first reason for choosing Lightroom: 1. Nondestructive Editing. Nothing is actually changed (by Lightroom) in an image until it is exported. This means you can make an adjustment, change it again and again, but no quality is lost as it would be with Photoshp. This is reported in Outdoor Photographer.
My impression is there is no lost of image quality in Photoshop if you are working on a layer copy of the Background. Photoshop tries to prevent degradation of the original image by requiring it be copied or otherwise freed before the background can be changed.
Image quality can be lost in downstream layers through processes such as changing image size.
Is my statement correct about loss of image quality and the 'analyst' from Outdoor Photographer misstating things?

Hi Vince.
I am just learning my way around Photoshp. I have spent 18 months learning how to start and to stop it.
Good point. But if we peg the learning curve of Ps at 10, Lr comes in around 2 or 3. Like learning to drive a car as opposed to learning to fly a jet.
Smart Objects would make PS more re-editable.
True, but still no match for Lr or Ps RAW.
I have never before seens a comment that extensive work on an image in PS would deteriorate the quality of the image.
Extensive work will do what the user asks it to do. In the first 18 months I had Ps, I asked it to do lots of things that I now realize deteriorated my images. Forever.
Regarding LR, I have created for me a workflow that requires PS.
So did everyone before Lr came out. And yet, Ps users by the thousands, if not millions, have adopted Lr. Many if not most with a greater time investment in Ps than 18 months. I dropped my Ps centric flo the moment I realized what Lr could do. I had been using Ps pretty heavily for about 5 years by that time.
I feel LR works best for experienced photographers who are shoooting a lot of pictures.
While it's true that experienced photographers might realize more benifit, maybe not. It works great for everyone.
That person has good images, images that need little editing, to start the output process.
This is not true in the sense that the majority of Lr users are mediocre photographers at best. For the simple fact that most photographers (even "pros") are mediocre at best. And Lr was conceived with these folks in mind. It has the true "pro" stuff, but in an amateur friendly environment. Judging by the images and questions posted on photo and Lr forums, there are many, many, low level photographers using it.
I am an inexperienced photographer shooting just a few pictures. So I put a lot of effort into getting a good print from my mediocre shots.
You obviously care about your images. Care more when you are shooting them. This is boiler plate advice. Time spent mastering your camera will pay off better dividends than learning to fix bad photos. This was true before the digital age, and it's just as true now. Ultimately, no matter how hard you massage it in Ps, Lr, or any other app, the quality of your final image will be a function of the quality of the original pixels you captured with you camera.
So far as masks and all the rest, Lr has an Local Area Adjustment Brush which does just that. You paint the mask, complete with any number or combination of adjustments, with a brush. The mask and the adjustments to it can be easily changed later. A good spot removal tool. A great red eye tool.
File size isn't a huge factor these days, but it still counts. Instead of layers and the pixel data for each of them as in Ps, Lr has the pixel data once, and a sidecar file with the adjustments settings in a much smaller file. Not a big deal for storage, but when rendering, maybe a bigger deal. Lr also pre-renders previews at various sizes (you can program this, plus how long it keeps them). I could go on and on (and I have).
Bottom line, it's a great tool for anyone who takes photos. For the price, it's a no brainer for $150. If you have the $150. Not true for many of us these days.
Anyway, Vince, I hope you don't think I'm picking on you. I answered you in detail because you made such good points. And the answers might be of general interest.
Peace,
Lee

Editing and image quality in Lightroom

Hello all,
I am a new Lightroom user (Lightroom 5) and I've watched several tutorial videos and I've had a lot of fun playing around with the program. I've noticed that Lightroom is said to be "non-destructive" when it comes to editing. Apparently, you can do all the editing you want to an image (i.e. adjusting exposure, cropping, etc.) and there is no loss of image quality as you edit. Is this correct?
I would hate to think that my tinkering around with the editing tools results in loss of image quality each time I change something. ("Hmm, I like that exposure. Now let me adjust shadows. No....that doesn't look right when I do that. I'll just change the exposure a bit more...."! I intend to put photos onto an image hosting site and present them, so I want the quality to be the best it can be!
I appreciate any help anyone can offer.
Cheers,
Tom

I know of no image editing software that causes loss of image quality when you make an edit. Editing steps simply cause a change to the image based on the edit you perform, not a loss of quality. This is true of Lightroom and every other image editor that I know of.
If you choose to save (or in Lightroom do an export) as a JPG, then there is a loss of image quality each time you perform a save as a JPG. If you need to have a JPG of your edited photo for some reason, then this loss of image quality is unavoidable, but in most cases you won't even notice. Thus, in Lightroom, creating a JPG from the edited photo is the LAST step in the process, thereby minimizing the image quality loss.

Poor image quality using iMovie 8 or iDVD after importing DV file via FW

Hello,
i am a complete newby and asking for help. I have bought a Panasonic NV-GS320EG-S miniDV Camcorder. First i connected it via S-Video to my Pioneer Plasma which worked fine.
I have connected the camcorder via Firewire to my iMac 20/2,4 GHz, camcorder will launch import window, streaming works but in iMovie the image quality is already rather poor. I can cut files and all but after using Import film and burning it with latest Toast, picture quality is even worse, that means colors are natural but no sharpness, lots of shivering lines as soon as the angle is moving.
I've tried to import directly into iDVD with the direct transfer function for Firewire which works technically as well but the result is mainly the same, when i burn the DVD the picture quality gets far worse than via S-Video connection.
Last thing i tried is importing to iMovie, importing for media browser and reopening file in iDVD which burns the DVD later, all that works technically fine, but the image result remains absolutely poor, my wife meant inacceptable...
Any ideas what that could be??? I've always imported and exported the film with the largest picture mode possible...

I am using the Panasonic HDC-SD5 camcorder which records in AVCHD.
I also have a JVC miniDV camcorder.
The following is available in iMovie 08 help:If the larger sizes are not available, the original project media isn’t large enough to render in that size. The largest media size used in the project determines the final movie sizes you can render.
Tiny: Always 176 by 144 pixels.
Mobile: Always 480 by 272 pixels.
Medium: Varies in size from 640 by 480 pixels (standard aspect ratio) to 640 by 360 pixels (widescreen), depending on the size of the media in your project.
Large: Always 960 by 540 pixels (widescreen). No large size is rendered if your original video isn’t high definition (HD).
