Very difficult due to the removal of features in Acrobat and Reader, and the total lack of support for rich media PDFs on third party and mobile apps.   You can embed a rich media "video" and set it to open in a floating window, but you cannot control where it is on screen, it will always have a thick black border, and you can't get rid of the background. You can still - just about - embed a rich media "SWF" object, which could be rendered on top of the page and without any enforced borders, but it would then scroll with the viewport. If you set it to float, you'll get those boarders back. It is theoretically possible for custom-coded video playback SWFs to load a .FLV file with an alpha channel - but Adobe killed off all the tools required to actually make them.   Adobe's development and feature policy is simple and has been set in stone for years. PDF is for "documents", and don't even think about making a document do anything jazzy and animated. HTML, ePUB or native mobile apps are for everything else. What you really want is a PDF equivalent of the HTML5 <video> object and dynamically-positioned page content, but that's not going to happen. ... View more

The "long string" is a UUID, which has so many possible combinations it is unfeasibly difficult for anyone to scan through them all to find everyone's documents. The UUID is the only "security" system for Publish Online - Adobe for some reason doesn't want to implement a login-to-view system like all the other providers do, so there cannot be options to make the URLs any more easily-guessable. If you were allowed to use "/view/secretfile1" then it's pretty much guaranteed someone else will try the same string, find it's already taken and immediately go read your document.   The simplest option to make things "easier" to type is to put the original URL through a shortener service such as bit.ly - their character sequences are of course much easier to scan through so there's a slight chance someone else could stumble upon it, but with millions of active sequences it's very unlikely anyone will try to visit every working link they find. ...

Documentation for anything rich-media or 3D in Acrobat has always been terrible; some things in the docs have never been implemented, some things in the code have never been documented. It was never much more than a proof of concept, and Adobe decided back in the Acrobat X cycle that the concept wasn't something they wanted to push forward. PDFs were just going to be boring documents, anything "interactive" was to be done in HTML or ePUB. Rich media and 3D made it into the Adobe extension to the ISO PDF spec so they couldn't just delete the code from Acrobat, but it got zero developer attention. They offloaded the 3D bits to Tetra, and left the Flash stuff to wither. It was never going to appear on mobile, none of the third-party PDF viewers could deal with it because they couldn't bundle the runtime, and these days the vast majority of people view PDFs on a phone or in a native browser window. It's not worth the effort to develop documents anymore, unless you're targeting a closed audience who can be forced to use Adobe Reader on a desktop computer.   The two embeddable SWFs "videoPlayer" and "audioPlayer" used by Acrobat and InDesign were pretty much out-of-the-box examples of the playback widget from Flash 8, hence the strange names of the function calls, and the Acrobat managers probably assumed people would go to the Flash Pro docs for help. Then Flash was 86ed and .. yeah.   The idea of video "cue points" in the Acrobat API is strictly a FLV idea, they are detected by the (closed source) FLV decoder in the Flash runtime and so the player gets to see them "for free". They are not the same as markers or XMP data in other video codecs, and since you can't make FLVs anymore that entire concept is dead on arrival.   As to keyframes, there are some third party apps that will analyze a video file and show the frame types (I and B) but by default an H.264 encoder creates them as it sees fit, based on how much a frame differs from the previous. That's why scene changes will create one. You can usually define the average interval between keyframes to aim for, and it's possible in some encoders to create H.264 files in "all-I" format where every frame is a keyframe, but at the cost of a much larger filesize. ...

As posted to your other thread, seek is only able to move the playhead to the nearest keyframe. How close that is to the time value you pass as a parameter depends entirely on how the video file is created. It is possible to create video files with keyframes at exact user-defined points, but it's not easy and if you plan to seek to "random" positions it won't help. ... View more

Multimedia_seek on video tells the embedded player to jump to the nearest keyframe for the specified time offset. How close it gets to the target depends on the keyframe intervals in your media files. As you've discovered the seek will always be consistent, but unless you craft a very carefully encoded media file with markers at the target points it will not be frame-accurate. ... View more

When transparency is flattened onto a background image, the PDFMaker engine tries to "optimize" the process by chopping the image into fragments, so that only those that have something layered above them need to be processed. It's possible to merge those fragments in Acrobat, using an obscure setting in the Optimizer tool.

Acrobat can certainly convert DWG files into 2D PDF sheets without needing AutoCAD installed, but it's a well-hidden feature!   Either use File > Open and change the file type dropdown to "All Files (*.*)" so you can pick a DWG, or drag and drop the DWG directly onto Acrobat's workspace. You will get a conversion dialog with various options, depending on what's in the DWG (multiple layouts, layers, etc.) but you won't see a preview, so you need to know beforehand what's in the file. ...

The "N-1" policy is new but strictly enforced. When Creative Cloud subscriptions first began one of the primary selling points was that you had access to every version of every app, and could choose if and when to upgrade or downgrade. Then the patent lawyers arrived, Adobe lost, and all the applications affected did indeed become "unauthorized". Your subscription may be valid, but Adobe is no longer allowed to distribute the old code. Simply using pre-2018 applications could in theory bring those lawyers to your door.   The old versions will never come back. See https://helpx.adobe.com/support/programs/support-periods.html   Adobe's native file types, with some very limited exceptions, have never been openable in earlier versions of the software - and often each program only allows down-saving by one or two increments. There are interchange formats for some types of file (e.g. EDLs for transferring edits in and out of Premiere) but After Effects is particularly nasty as nothing other than After Effects can open an AEP file, and After Effects will not save projects to anything else. Ultimately you and your clients must either use the latest versions, or switch to non-Adobe applications. There are plenty to choose from. ... View more

Sounds like whatever you purchased was designed for an old version of After Effects, before many of the Quicktime codecs were dropped. The Keylight warning can probably be ignored unless it's obvious that something isn't looking right, but if you have source files that use legacy QT codecs there's nothing you can do about it; they will have to be converted before After Effects (or anything in CC) will read them.   See https://helpx.adobe.com/x-productkb/multi/quicktime7-support-dropped.html ...

[ moved to Photoshop forum ]   Looks like a resolution problem - the pixels in your black "zoomed in" image are larger than in the magenta one and a significant size compared to the circles you're looking for - plus there seems to be some anti-aliasing in the magenta version. It's hard to tell from your screenshots as this %^*$*^)$ forum doesn't show images full-size, but when you converted the magenta image from Bitmap to RGB, did you use a size ratio bigger than 1?   Remember the resolution stuff in the Bitmap conversion popup is quite confusing; the "output" resolution in the first popup causes a resize of the image, so all the halftone values in the second popup are based on that. ...

Lack of metadata preservation was reported when the whole "Export As" thing was still in beta - many years ago - and the programming team have completely ignored the problem ever since.

Assuming the image dimensions and position don't need tweaking, then you can simply replace the external file on disc and re-open the AEP file.
