Best practice to put overlay images on video?

Hello community!
I would like to know what's the best way to put overlay images on videos, like ads ( actually ads )
I'd like to animate them and all that stuff, the thing is I believe I know how to do it, but I'm not sure.
On the one side I image that i should create a plugin to manage them, and a MediaElement to put them inside.
Supposably this mediaElement ( Ads ) should run in Parallel with the video.
I'm still investigating on that but I would appreciate any help!
Thanks!

Yes, you're on the right track. See this sample app for some additional guidance:
http://opensource.adobe.com/svn/opensource/osmf/trunk/apps/samples/framework/LayoutSample/
The sample demonstrates the layout of an overlay bug by placing a VideoElement and ImageElement in a ParallelElement. To map this to the ad use case, you might have the ImageElement encapsulated within a plugin.

Best practice for importing non-"Premiere-ready" video files

Hello!
I work with internal clients that provide me with a variety of differnet video types (could be almost ANYTHYING, WMV, MP4, FLV). I of course ask for AVIs when possible, but unfortunately, I have no control over the type of file I'm given.
And, naturally, Premiere (just upgraded to CS5) has a hard time dealing with these files. Unpredictable, ranging from working fine to not working at all, and everything in between. Naturally, it's become a huge issue for turnaround time.
Is there a best practice for preparing files for editing in Premiere?
I've tried almost everything I can think of: converting the file(s) to .AVIs using a variety of programs/methods. Most recently, I tried creating a Watch Folder in Adobe Media Encoder and setting it for AVI with the proper aspect ratio. It makes sense to me that that should work:using an Adobe product to render the file into something Premiere can work with.
However, when I imported the resulting AVI into Premiere, it gave me the Red Line of Un-renderness (that is the technical term, right?), and had the same sync issue I experienced when I brought it in as a WMV.
Given our environment, I'm completely fine with adding render time to the front-end of projects, but it has to work. I want files that Premiere likes.
THANK YOU in advance for any advice you can give!

I use an older conversion program (my PrPro has a much older internal AME, unlike yours), DigitalMedia Converter 2.7. It is shareware, and has been replaced by Deskshare with newer versions, but my old one works fine. I have not tried the newer versions yet. One thing that I like about this converter is that it ONLY uses System CODEC's, and does not install its own, like a few others. This DOES mean that if I get footage with an oddball CODEC, I need to go get it, and install it on the System.
I can batch process AV files of most types/CODEC's, and convert to DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio and at 29.97 FPS (I am in NTSC land). So far, 99% of the resultant converted files have been perfect, whether from DivX, WMV, MPEG-2, or almost any other format/CODEC. If there is any OOS, my experience has been that it will be static, so I just have to adjust the sync offset by a few frames, and that takes care of things.
In a few instances, the PAR flag has been missed (Standard 4:3 vs Widescreen 16:9), but Interpret Footage has solved those few issues.
Only oddity that I have observed (mostly with DivX, or WMV's) is that occasionally, PrPro cannot get the file's Duration correct. I found that if I Import those problem files into PrElements, and then just do an Export, to the same exact specs., that resulting file (seems to be 100% identical, but something has to be different - maybe in the header info?) Imports perfectly into PrPro. This happens rarely, and I have the workaround, though it is one more step for those. I have yet to figure out why one very similar file will convert with the Duration info perfect, and then a companion file will not. Nor have I figured out exactly what is different, after running through PrE. Every theory that I have developed has been shot down by my experiences. A mystery still.
AME works well for most, as a converter, though there are just CODEC's, that Adobe programs do not like, such as DivX and Xvid. I doubt that any Adobe program will handle those suckers easily, if at all.
Good luck,
Hunt

Best practice for putting together scenes in a Flash project?

Hi, I'm currently working on a flash project with the following characteristics:
using a PC
2048x1080 pixels
30 fps
One audio file that plays (once) continuously across the whole project
there are actions that relate to the audio, so the timing is important
at least 10 scenes
about 7 minutes long total
current intent is for it to be played in a modern theater as a surprise
What is the best practice for working on this project and then compiling it together?
Do it all in one project file?
Split the work into different project (xfl) files for each scene and then put it together when all the scenes are finalized?
Use one project file but create different "scenes" for each respective scene? I think this is the "classic" way (?).
Make the scenes "movie clips" and then insert them into the timeline with the audio as its own layer?
Other?
I'm currently working on it by having it all in one project file. But I've noticed that there's some lag (or it gets choppy) at certain parts during playback and the SWF history shows 3.1 MB with a yellow triangle with exclamation point symbol. Thanks in advance.

you would only do that if it makes your job easier. generally speaking, it would not.
when trying to sync sound and animation i think most authors find it easiest to use graphic symbols because you can see their animation when scrubbing the main timeline. with movieclips you only see their animation when testing.
however, if you're going to use actionscript to control some of your symbols, those symbols should be movieclips.

Best practice for putting binary data on the NMR

Hi,
We're creating a component that will consume messages off the NMR, encode them, and subsequently put them back on the NMR. What's the best practice for sending binary data over the NMR?
1. setContent()?
2. addAttachment()?
3. setProperty()?
If NormailzedMessage.setContent() is the desired approach, then how can you accomplish that?
Thanks,
Bruce

setContent() is used only for XML messages. The recommended way to accommodate binary data is to use addAttachment().

Best practices / workflow for importing images?

Is there a recommended workflow or best practices for importing images into the library? Specifically, I want to know -
1.) Is it better to import /store the Masters right into the Aperture Library
or
2.) Is it better to move / store the Masters into a folder you specify and reference them?
Even more specific, is there any advantage in storing the Masters in the Aperture library?
As I'm determining how I want to do my workflow, (New Aperture user, so I want to design my workflow from the start) I am thinking that the later would be the way to go, storing them not in the library, but in a folder as a referenced image. My reasoning is as follows
* Images more readily available for other applications, without having to do an export
* Library database remains small, storing only the versions (less chance of corruption perhaps?)
* Eliminate any issues with Time Machine - TM would backup the folder where the Masters are stored, and only need to update when new files are imported there. Also thinking that TM would have less issues backing up the Aperture library.
So can someone either confirm my reasoning or tell me I'm way off base and should store the masters in the library, and why.
Thanks in Advance!

This link has a pretty good summary of the pros and cons of each method. Neither one is perfect of course. Otherwise this question would be easy to answer!

Does JSP best practice of putting under WEB-INF apply to JSF pages?

I'm new to JSF and wondering if the "best practice" advice that used to be given of storing your jsp pages under WEB-INF (when using Model2) to keep them from being served up without going through your controller still applies with JSF.
Since the component lifecycle is so different, I'm wondering if it would still apply? If anyone can explain why it might or might not apply I'd appreciate it!
Thanks!

The rule is:
keep all the pages you don�t user to "browse", under the WEB-INF directory.

Best practice for displaying an image

Hello everybody,
I have an application that displays and animates several
images and I was wondering what was the best way to improve
performance.
Is it better:
- to create a Bitmap object, put it in the display list and
then move it around
- create a Sprite, do a graphics.beginBitmapFill and a
drawRect, and then animate this Sprite.
Using one method or the other doesn't make a big difference
for me, but I was wondering if there is a difference in terms of
performance and memory usage.
Does anyone know ?
Thank you.

I don't think there is currently a way to do this in Catalyst (unless you create multipe text fields). I'd suggest setting it up in Flash Builder.

Best Practice for Text Wrapping Image?

I want to have a text block with an image in the upper left, the text wrapping the image. I can create it in Photoshop by editing the path of the text box, but it turns square in Catalyst (not surprising...) I know that in Flash Builder, you do it using html with an align=left image embedded. Is there a way I can do it in Catalyst, so that I don't have to do it by hand after the Catalyst->Flex transition?

What are some of your best practices for using videos in your marketing campaigns?

As video becomes more and more popular, what are some best practices you have for effectively using video in your marketing campaigns? Any cool examples?

Just saw this topic.
We use video a great deal in our campaigns. One of our best ones though was for an offering that the written word couldn't convey as quickly, succinctly, or visually even with graphics that a short commercial could do. We therefore created a simple video with professional VO work and blasted it out via email and social networks. The video clearly communicated our product and it's value to our prospects.
In return we got a enormous response of form submits from individuals wanting to download the products overview documentation. It is still one of our most watched videos.
We are now looking at adding in more value-add videos to go along with the current 'product information' stable to help generate more soft-sell opptys.
We are firm believers in using video. You can't just put anything out there and expect just because it is a video to do well. You must plan it carefully, think the messaging and value offered through just as much as any outbound offering. Time is still valuable and your prospects are always asking what's in it for me. Once they get something that they believe wastes their time, they will be more skeptical in the future regarding your videos or any messaging.
Keeping trust and relevance is essential to generating value with video.

Must use Captivate v4.0 to capture playing video - Best practices & PC requirements?

Hi all,
I like Captivate, but have had a lot of trouble capturing playing video (a big part of my client's product) in the past. Despite encouraging client to consider other tools, they have decided they want to continue using Captivate and output to SWF. Some of us on the team for a previous project using v3.0 were able to successfully capture moving video, others weren't. (Vaguely recall something to do with a Hardware Acceleration setting, but it didn't work for everyone.) We've all upgraded to v4.0 but haven't used it yet. My questions are:
1. Has this been improved at all in v4.0?
2. What is the "optimum" PC hardware for doing this? (I am purchasing a new desktop, and need to keep cost to a minimum, BUT that is secondary to being able to produce these demos with moving video captured well!)
3. Can you give me any best practice tips specific to capturing moving video? FYI, we will be adding audio narration (after capture), but will not be using written captions except for a few Notes/Tips.
Thanks in advance for your help!

Inline Figure Numbering: Best Practice

Hi all,
I'm seeking input into what the best practice is for numbering images/figures that are placed inline in a document. I want these figures to have consecutive numbers and to move with the text as the text is edited.
The crucial part is that I want to do this in a way that I can put a new figure into the document, and all the following figures will be renumbered automatically.
I can do this if I use a different "Figures" master page that is applied to pages that contain ONLY figures and no text, but I can't seem to figure out the best way to do it inline throughout the document.
If I anchor objects inline, in the order that I want them to appear, the numbering works just fine, but as soon as I insert and anchor a new figure in the middle with automatic figure numbering, the newest anchored image becomes "Figure 1" and renumbers the entirety of the document.
Thanks!

As long as I have all my figures I want to use, and I insert and anchor those figures in the text in the order that I want them to be in, it works. I am using a paragraph style for figure numbers.
The issue is that as soon as an update to the manual occurrs (a common occurrence in this manual) and I need to add a new figure (with a new figure number) halfway through the document, it numbers the new figure as Figure 1, and completely screws up the number formatting the rest of the way through.
I'm trying to set it up right the first time, so it works correctly for years to come.

Best practice ? send Object to request or desired pieces of data?

Newbie to this style of programming...
Is the best practice to put the customer object in the session or request object and allow jsp's to declare and instantiate the customer object out of the session/request (then use whatever getters are needed to properly display the desired data)?
Or would it be better to send the customer ID, Name, address etc as a string to the session/request object and just have the JSP declare the strings & instantiate from the session/request object(thus keeping more complicated java code out of the jsp)?
Thanks for the help in advance!

Doesn't this result in more code? If we send the object, we need code to declare and instantiate the object, then use the getters to get the data to display.
If I just send the necessary data, I just need to declare a string = request.getParameter... or just display the request.getParameter.
I actually like the concept of sending the object, it seems cleaner and less likely to result in servlet changes down the road, but i want to make sure there is not some other reason NOT to do this.

Spark Dropdownlist rollover rollout best practice?

I am seem to be having an issue here. I am trying to get a Spark DropDownList to open on mouseover or rollover and close on mouseout or rollout, but not if the mouse is on popup. But if the mouse rolls out or mouses out of the popup it should also close. The issue is when you use rollover on dropdownlist, plus rollout, when you try to move your mouse down to the popup it closes as it hears the rollout.
Does this code go in the skin? Do I need to extend the DropDownList? Not sure what is the best practice with addition of Spark and Skins?
Thx, J

Probably not best practice but put a rect in the skin and pushed it (top = -20) so my rollout handler sees it.

Best practice for navigation

If I don't want to use the playbar and want to have my learners click buttons to navigate through a lesson, is it considered best practice to put the buttons on each slide or to put them as widgets on the master slide?
Will the buttons on each slide make the published file significantly larger?

Hi again,
I never create a self-playing slideshow with Captivate? The main reason why I preferred Captivate over other rapid eLearning software a couple of years ago when I did compare possible solutions was precisely that it was so easy to create interactive simulations and have branching to personalize courses. Of course I started by using it for software training and both the Training simulation and Assessment capturing mode are suited for this goal. Sorry for my answer, but was puzzled by your remark that a self-playing slideshow is default? Feel free to ignore this, please, you probably do use CP with something totally different in mind.

Importing/Transcoding best practices

Hello
Apologies if this is a very basic question: I just returned from Africa and I have many hours of video as a result. All videos are 1080p, high quality and what not, and vary from 30s to 30 minutes in length. Therefore, some files are a few megabytes, other, a few gigabytes.
The output for my project is no more than 7 minutes or so, therefore I have to cut a lot.
My question: what is the best practice when you have this much video? Should I import and transcode everything (all 73GB of video) or is there a best practice to say cut what you need, then transcode that.
I am using a MBPr 15" with 16GB and 512GB, so I've unchecked the "Copy files to Final Cut Events Folder" in order to not eat up my local HD.
Anyhow, any advice would be really appreciated, thanks again
Rob

First, thank you for your quick reply and being very nice to me seeing as my questions are probably very basic. I have purchased a book on FCPx but it didn't deal with workflows very well, especially with what I'm dealing with.
"I'd suggest you acquire a large external drive":
Done, I'm using a 1TB USB3 drive specifically for this project. All videos are loaded onto the HD and when I began importing, I checked off the option to "Copy files to FCPx events folder" in order to centralize my content to the HD. That said, the Events Folder on the local HD DOES have content, pointers I believe. Should I be backing those up to the external HD?
"Before capturing footage create a CDL (capture decision list) and capture what you intend to use."
Not done. Some of the footage I have didn't lend itself for this unfortunately. For example, I had a gopro camera mounted on my head and another mounted on the head of a local tribesman while we went hunting for small game (their food of course). So the videos are long and I'd like to include portions of it into the final video. Is the only option for me to import and optimize the whole thing, or can I import, not optimize, review, cut, save the portions I like, then optimize those sections?
I'm hoping you can spare a little more patience for me. I'm a photog so my workflow there is solid. I'm very new at this and I'd like to get better. The management of files for me is key so I want to get off on the right foot.
Cheers
Rob
