Multi rendition folio size

hi there,
i've read an article about Apple forcing us to build (at least) retina versions of our new apps, starting from Mai 2013.
Can someone tell me if this really true ?
If I want to build multi-renditions or retina versions:
- is it right to work with photoshop (layered PSD) images at 264dpi and scale them down as needed inside InDesign or is it better to do all scaling inside Photoshop and do a 'safe for web' as JPG ?
- do I have to include video at 1080p or will 720p be enough ?
At this point I did a little test. Adobe Media Encoder created 720p and 1080p versions of each videoclip in a magazine. Inside the InDesign document I've linked to the 720p videofile. Filesize of the folio on the iPad was 478Mb.
Then I've put the 1080p versions inside a 'HD' folder together with the corresponding 720p file. Filesize of the folio grows to 932Mb.
Can someone inform me if this the way we have to build our folio's from Mai 2013 on ?
Thanks in advance,
Herman Belgy

Hi there. I have been uploading my articles as a PDF as we discussed, so that every ipad version can have the highest res possible.
Bob, you said I should ignore this link...
http://helpx.adobe.com/digital-publishing-suite/help/creating-dps-content-different-ipad.h tml
I'm still confused.
Should I be doing this? (as stated in link) (My articles are horizontal only and 1024x768)
Create 1024x768 and 2048x1536 renditions
When you create folio renditions, the iPad SD models display only the 1024x768 rendition and the iPad HD displays only the 2048x1536 rendition. You can use either the same set of source files (recommended) or two different sets of source files to create the renditions. For additional guidance, see the articles by Bob Bringhurst and Colin Fleming linked below.

Multi-rendition folios and 108ppi resolution

Experimentation with multi-rendition PDF folios is throwing out some interesting things. I am in a sharing mood.
- A standard iPad 2 folio rendition resamples images to 72ppi. An iPad 3 folio rendition resamples image to 144ppi. A multi-rendition folio resamples images to 108ppi. As a result, images in a multi-rendition folio look worse on an iPad 3 than those in an iPad 3-specific folio. Sure, if the original images are not very good, readers won't notice any difference, but for top-quality photography, the jaggies and jpegging noise are noticeably harsher.
- All raster MSOs in a multi-rendition folio will be resampled to 108ppi. If those MSOs contain text, that text will appear fuzzy/jaggy on an iPad 3 even without zooming in. MSOs must therefore be set to Vector format to preserve the text... but remember that any text incorporated into a raster graphic will still be resampled to 108ppi, then fuzzed up onthe fly to 144ppi on the iPad 3 screen. So if someone is supplying you with logotypes, for example, insist on vector illustration files.
Clearly, the 108ppi resolution of multi-rendition PDF folios is a compromise. I'd be a little happier with this resolution compromise if it was possible to adjust JPEG compression settings for the images.

Hi Bob
I've just created a large report and did what you suggested, duplicate the image, and turn it into an mso and then added the HD folder. Nothing looked different, so I tested on of the images in the HD folder by adding the word HD, tested on iPad 3 and it didnt pick it up. I've made sure the file names are exactly the same. The files are tiff's.
Have I missed something? all my SD assets are in a Links folder, with all the other assets, and then I created the folder "HD" with the hi-res images in there, and thats it. The 1024x768 folio is linked to all the normal images, but retina version is not picking up the images from HD folder
Anything obvious missing? oh and I'm on release 23
Cheers

Multi-rendition Folios

Do multi-rendition folios work in Creative Cloud versions of DPS?

They were specifically created for the Single Edition use case. They are only valuable if you are using pan and zoom overlays in your publication. If you aren't there's no point to them, just use a 1024x768 folio in PDF format.

Creating multi-rendition (retina and non-retina) from one folio

Hi there,
We'd like to create a multi-rendition folio from a single, retina-sized set of source files. I've seen this discussed in a few places, but am not sure of the workflow. Is anyone able to point to a guide for doing this?
Thanks in advance,
Toby

Anything two years old pertaining to DPS is too old to take with anything
but a grain of salt. Things have changed dramaticallyand for the better.
When that article was written, renditions were the only way to support both
retina and non-retina devices.
Try it yourself. Create a few test articles and turn them into folios with
PNG at 1024x768, 2048x1356, and finally a PDF folio at 1024x768 and make
your own judgements.
Barring some incredibly high end need, I'm pretty confident that you'll have
a very difficult time justifying the extra work of doing renditions. But
should you have a certain graphic that you feel needs to be 144ppi you can
can create a one state image sequence using the hd/sd assets.
Finally, unless you have a pro or enterprise account, this is moot. Single
Edition apps do not support renditions. Here' a link to one I did recently:
https://itunes.apple.com/us/app/my-9-months/id528623198?mt=8
Check it out. It's done as I described above. 1024x768 PDF.

Reducing folio size

Hi all,
I am struggling to reduce the folio size of an app, and need to better understand why this is. I need to be able to explain to my client why reducing the size of the images has not made a difference - as this logically makes no sense.
I have created renditions for the iPad, Android and iPhone. It is quite an image-heavy folio, so the size for all 3 devices is large (my client has complained that it is too large, as users are expereiencing problems with the download).
I contacted Adobe and was advised to reduce the size of the images for each device. I changed the resolution to 72ppi, and saved for web as jpg with medium/high compression. I also uploaded the folio as PDF, hoping this would keep the size small.
However, compared to before editing the images, the iPad and iPhone folios reduced by a mere 2MB, and the Android folio even increased! This just does not make any sense to me, and if I don't understand why this is, I won't be able to explain it to my client either.
I'd appreciate a logical explanation, and perhaps some advice on how to reduce the folio size (in addition to the image size reduction and uploading it as a PDF folio).
If someone could reply to this soonest so I can get back to my client with a satisfying answer, that would be much appreciated. THANKS!!!

Image/Video Optimization is all about compromising with logical thinking and testing employed. In both cases - image and video - there is amount of information that is compressed into the file. The more informative (more detailed, larger size) the image is the less it could be compressed and the bigger you will get the file.
If there is a video in the folio then you need to optimize it first as videos are much more hungry for the size.
To make image smaller several things could be done:
- you may choose less informative picture, e.g. empty swimming pool vs crowded one;
- you may crop different/smaller part of the original picture;
- some effects like when one part of the picture focused and the rest is foggy or grainy picture will also reduce the size;
- replace background for less busy one, e.g. put the image behind the window ( the plain wall around the window is not that informative, isn't it? );
- lower the quality of the image until it's on the borderline after which it becomes unacceptable;
- prioritize your images - make some of them smaller pixel wise, some with better quality then the average through the folio and some with less, and some replace with less informative alternative image that could fit for the purpose even better, and some excessively used just delete.
Image is a 3D object as each 2D pixel of it has the 3rd coordinate - color. So the less bits are used to code the color the smaller the image. Also the more areas with the same color the better the compression: if we reduse1000x1000 pixels photo quality image to 500x500 ( 4 times ) and then enlarge it back to 1000x1000 we will get each 1 pixel of 500x transformed to 4 pixels of the same color.
Now you just need to test the settings to get the quality-size borderline for each or most of your images. I would start with the new empty folio and add one of your average images to it - this will allow you to compare size of the optimized image to the size of the folio file and get the idea of the folio format overhead and possible transformation to the image. You may also look into article's articlename.folio file - it's just a plain zip file with all the images inside, so rename it to articlename.folio.zip and open.
Here you can also read Google's recommendations:

Plus as always you may search DPS/web for more info.

Maximum folio-size (single-folio apps)

Hello,
I am searching for the maximum folio-size of single-folio apps.
Can someone help me in this case?
Thank you in advance!
Regards,
Sebastian

I think it's around 2 GB, however it's best if you keep it less than 700-800 MB.

Ways to decrease the folio size

hi there,
just designing the second issue of a monthly i-pad magazine, folio size = 425Mb and looking for ways to reduce it to arround 350Mb.
What I've already done
- compressed al video to mp4 - 720p with Adobe Media Encoder (using the 720p-25frames ipad setting found there)
- folio + all articles and as much as possible of the interactive elements are set to pdf
But all images (a lot) I'm using are imported as large resolution PSD files.
Someone about whether I can reduce the file size by scaling them down and saving them as jpg ? I thought InDesign did this for me but maybe I'm wrong.
All other suggestions about reducing folio size are more then welcome.
Thanx in advance,
Herman Belgy

There is a limit to how much you can decrease the file size. Static elements in PDF folios are rasterized at 108ppi (half way between 72 and 144). The videos are really your best bet but at a certain point you'll kill the quality.
You could stream them but that will require the user to be on line.

Folio size doesn't match asset size

Hello, I have another question.
I'm building an article with multiple pages, that's fairly asset heavy. There are seven pages, and each has an MSO with between 6-10 states, containing an almost full-page image in each state. We've reduced the size of each image to around 100KB, so each page should only weigh about 1MB. For some reason, when I'm building the folio, each page adds about 10MB to the folio size. The entire article ends up being almost 100MB! I was expecting it to be on the heavier size, but ten times what I expected was a bit of a shock!
I've recreated the page from scratch, relinked the images, and started a new folio, but each time the same thing happens. Is this jump in size simply because of the number of pages and large ammount of MSOs? It is the only reason I can come up with for having such a large jump in file size. If this is the problem, is there any way to fix it?
Thanks for any help!

Hello,
What is the purpose of all your multistates?
Are they image galleries? - if so try and use a HTML image swipe instead;
MSO's (especially full page MSO's) are notoriously weight heavy - for reasons that make no sense they seem to pile the weight on irrellevant of your asset size.
Very annoying, but I've never found a fix! Maybe someone on here has though, good luck!

Digital Blow in and Multi Orientation Folios

Hi there,
stoked to be using the reading api and digital blow in features discussed here.
we're using it in this app, and it appears we've discovered a bug, whereby if you produce a multi-orientation folio, then the web-overlay only works on the portrait orientation, not the landscape?
Are you able to confirm if this is a bug or not? If so need to know of a workaround we can apply for this, and a timeframe for when this can be fixed?
thanks, love your work.
Conor.

So I did that, expecting a timely response. it's been a week and Adobe boast of one hour for response time. Very frustrated to essentially be a beta tester for Adobe's new features and software and not getting anywhere. For the record, we publish magazines that are featured on newsstand - not that makes any difference, but it's pretty furstrating to have to follow this up... it needs to be documented.

Why does folio size remain same when images are sized down?

In the constant battle to keep the folio size down, I found and eliminated a stray print-size image (40mb) and replaced it with a 2mb file however my folio is still claiming the same size when I see the update come in. Any idea out there why a folio will hang on to its size in this case.
Thanks in advance

Because we automatically resize the images to 108ppi at the pixel dimensions of the containing frame. A 40MB print image doesn't pass through to the folio as 40MB. It'll get sampled down.

Can you make a folio size of 1000 x 750 for iPad?

I have made a test folio this size and I can't seem to get it to load on Adobe Content viewer unless I have the iPad plugged into the computer. Is there a reason why? I am still in 25v. One of my ipads has IOS7 the other does not.
I am going to answer: NO
It appears that ipad doesn't want to load that size. So to make my android users happy I am going to have to make a 4th folio size. ugh!

No, you can't. The iOS viewer will only open 1024x768 or 2048x1536 folios (well, there's two other sizes that work, but that's really for Woodwing users and they are only a few pixels different).
Trying to get an exact screen size match for Android devices is an awful lot of work for very little benefit. There are simply too many different Android sizes. Instead you can take advantage of the feature in R28 on Android where we will scale folios up as well as down to fit the Android screen. Then one version, published as PDF for Android, can scale quite nicely for all the different screen sizes there. You could even use your iPad 2 folio for this, assuming you don't have any Apple-specific content.

Check folio size

Is there a way to check the size of each article within a folio (either uploaded or local)?

Although this is a way to find out, surely Adobe need to introduce a more intuitive way of finding out a folio size. It would also be helpful to see within folio builder how large each article is, that way, if the folio is too large we could pinpoint a particular article and work to reduce the size of it. At the moment the only way to find out a folio size is to download the whole thing in content viewer and then find out. Surely there need to be a way of finding out before you've downloaded the whole thing??
Surely within folio builder you should be able to slect your folio, click on properties and that would tell you the size?
Thanks

DPS Folio Sizes

To DPS Users,
Could anyone offer advice on combining folio sizes to produce one single folio file.
IE: 1024 x 2000 x 1024 x 768 what would be the largest scrolling length folio that can be used within DPS.
Regards
Vividi

I am working in Adobe InDesign CC 9.2
Mac OS X 10.7.5
When I open the Folio Builder Panel in InDesign this appears:
"You do not have a compatible Digital Publishing Plug-in. Click here to download the Folio Producer tools."
I have installed, uninstalled, reinstalled, these several times, and performed the two troubleshooting suggestions as throughly as possible
No progress yet

Adobe DPS Android - Folio Size Best Practice

Hey everyone,
we designed a magazine for iPad and now want to bring it over to Android. A little bit of research and it seems, that the Samsung Galaxy Tab 7' is one of the most popular tablets. Second to that is the 10' Samsung Galaxy tab.
The problem I know have is, for which resolution I should re-do my magazine to work on most android devices.
I read about it (http://blogs.adobe.com/indesigndocs/2012/10/creating-dps-folios-for-android-devices.html), but still would be happy to hear from you guys regarding the following things:
Would it be wise do set a new folio size 1280x800 (to cover the 10')? I think it will be automatically scaled down to 7' on smaller tablets, right?
Or is it the better approach to work with an addiotional folio size 1024x600 to target the most popular tablet with 7'. As I recall correctly, the content will not be enlarged on larger tablets like 10', right?
What if I have a retina-Android-Device. Does the folio automatically scales up like on iPad?
Personally I would think that approach 1 is the one which makes most sense. content will be displayed fine on 10' and 7' with content slightly smaller on 7' (just like iPad retina and iPad mini).
What do you guys think?
Thanks a lot in advance!

We starting to test publish to Android. Our 1024x786 PDF iPad edition is showing OK on content viewer for android. There is black boarders, but with pich and zoom, it's perfectly viewable. HTLM and web content works fine. We simply don't have the time to recreate folios at various sizes. So our solution works for us.

How do you share and view multi article folios on any desktop computer without DPS?

How can one view a multi article folio on a desktop computer, mac or pc, using the Adobe Content Viewer?
I need this for desktop sharing purposes, for people without DPS of any other Adobe software installed (except for probably Content Viewer).
It`s an interactive brochure that needs to be spread among a number of people. Some use mobile devices, but others use Desktop computers.
Thank you.

DPS is essentially a mobile publishing platform.
The only desktop ACV that is available is for Windows 8.1. Otherwise these
folks need tablets.
