Uppsala, Sweden - Inzomia has released Fast Video Cataloger, a video asset management system for Windows that lets video professionals catalog, search, and find video clips in seconds instead of hours. Fast Video Cataloger scans each of your video files and builds a series of evenly-spaced thumbnail images of the video. Each thumbnail acts as a bookmark. Simply click a thumbnail, and the video is immediately launched at that point in the video.
Cataloging of new videos is automatic, fast, and runs in the background as you use your PC for other work. Point to files or folders that contain videos, and Fast Video Cataloger will scan each video, build thumbnails, and add the information to its catalog.
Fast Video Cataloger delivers several ways of categorizing and retrieving video clips. It's easy to add tags to any videos, as well as information about the content of the videos. Keyword searches will quickly identify all videos that contain relevant footage. You can even manually add new thumbnails to your video as you watch it. With its combination of tagging, rating, categorizing, describing, and linking, Fast Video Cataloger makes it simple to find and retrieve video clips.
Fast Video Cataloger does not require any special server configuration or support from the IT Department. The software runs on any modern Windows PC. Because Fast Video Cataloger runs locally, there are no huge video files to upload, and no file format conversions are needed.
Sportscasters can use Fast Video Cataloger to parse historical footage of games and interviews and retrieve video clips when they're needed. News professionals can search video archives in minutes and retrieve the information they need for newscasts and b-rolls. Public relations managers in larger enterprises can locate video clips from corporate advertisements, annual meetings, and other archive footage. Professional videographers can use Fast Video Cataloger to scan their earlier work to find clips to include in proposals to new clients.
Fast Video Cataloger runs under Windows 7/Vista/XP with .NET framework. A single-user license costs $197(US). Multi-user discounts are available. You can download a trial version of Fast Video Cataloger.

GIFs from Videos
How to create GIF files from your video clips
The world wide web just turned 20. Even older than the www is the GIF file format. The format is flawed in many ways, its limited to 256 colours. The compression isn't very good and it used to be patented. Now the patent has expired and even if the format has some flaws there are still situations when gif is the right format to use.
The two huge advantages of the GIF format is that it supports animations and that it is supported by all versions of all web browsers. Since no plugins or special codecs are required to play the GIF they just simply work. And even if a gif might be a bit larger than for example a short flash file the load time is often offset by the time it takes to load and initialize the flash player.
You can use GIF files where no other format works.
I created a simple tool to convert a video clip to a GIF file including converting it to 256 colours and resizing it. You can also add single images or create the animation from single files.

Using Photographs to Enhance Videos of a Static Scene
I forgot to write about this a when it appeared a month ago, I am sorry about that.
If you have not seen this already you really owe yourself to check it out, it will blow your mind.
"Using Photographs to Enhance Videos of a Static Scene" is a research project that shows a way to combine high quality photos with videos taken at the same location. The result so far is research and not available in any product but it paints a bright future. Using their method they are able to increase the resolution of the whole video clip, create high dynamic range videos and to enhance exposure. They are even able to remove objects from a scene.
Checkout the project page with the complete paper and an amazing video presentation.
When you watch you can also keep in mind that a lot of companies are working on digital cameras the combine high quality photos and videos recording. There is currently a lot of research going on into computational imaging using image recognition software together with novel hardware. For example there are already digital cameras that combine video and photo to automatically take a group photo when all have their eyes open is closing their eyes.

Remove motion blur from videos
When you take move the camera while taking a photo you get motion blur. At this years Siggraph conference there are several papers about how to remove motion blur from images. Take a look at this paper High-quality Motion Deblurring from a Single Image that uses a single blurry image as source and makes a virtually perfect photo. The screenshots are quite amazing. As people from Abobe are part of the paper we can hopefully sees this as a filter in future versions of photoshop.
Using this teqnique together with a video frame capture software like fast video indexer could create really awsome screenshots from videos.
The abstract for the paper:
"We present a new algorithm for removing motion blur from a single image. Our method computes a deblurred image using a unified probabilistic model of both blur kernel estimation and unblurred image restoration. We present an analysis of the causes of common artifacts found in current deblurring methods, and then introduce several novel terms within this probabilistic model that are inspired by our analysis. These terms include a model of the spatial randomness of noise in the blurred image, as well a new local smoothness prior that reduces ringing artifacts by constraining contrast in the unblurred image wherever the blurred image exhibits low contrast. Finally, we describe an efficient optimization scheme that alternates between blur kernel estimation and unblurred image restoration until convergence. As a result of these steps, we are able to produce high quality deblurred results in low computation time. We are even able to produce results of comparable quality to techniques that require additional input images beyond a single blurry photograph, and to methods that require additional hardware."

Self animated images
Video - A series of framed images put together, one after another, to simulate motion.
Did you know you can get away with only one image and let the brain to the work of animating the image. If you make an image in the right way your brain will fool you into animating the image yourself in you head.
Siggraph is THE yearly conference on computer graphics. This year, as usual, there are a lot of interesting papers that to be presented and some of them are already beginning to leak out.
The effect is much better if you click the image and view it as large as possible
As I develop a video software that takes videos and generates images from it a paper about Self-Animating Images got my attention. In Self-Animating Images: Illusory Motion Using Repeated Asymmetric Patterns scientists, Ming-Te Chi and Tong-Yee Lee and Yingge Qu and Tien-Tsin Wong, propose a computational method to generate self-animating images.
Even if you are normally not interested in scientific papers take a look at the pictures in it anyway. On the project page there is also a link to a pdf with more example images. Read the instructions on the page for how to best view the images.
Here is the summary from the project page:
"Illusory motion in a still image is a fascinating research topic in the study of human motion perception. Physiologists and psychologists attempted to understand this phenomenon by constructing simple, color repeated asymmetric patterns (RAP) and found several useful rules to enhance the strength of illusory motion. Based on their knowledge, we propose a computational method to generate self-animating images. First, we present an optimized RAP placement on streamlines to generate illusory motion for a given static vector field. Next, a general coloring scheme for RAP is proposed to render streamlines. Furthermore, to enhance the strength of illusion and respect the shape of the region, a smooth vector field with opposite directional flow is automatically generated given an input image. Examples generated by our method are shown to evidence the illusory effect, and the potential applications for entertainment and design purposes."

Flash is now open source
Adobe finally on the 1st of May announced that they will turn Flash and some related technologies into open source. The new open source initiative goes under the name of open screen is backed by a number of really large media and hardware companies like:
ARM, Chunghwa Telecom, Cisco, Intel, LG Electronics Inc., Marvell, Motorola, Nokia, NTT DoCoMo, Qualcomm, Samsung Electronics Co., Sony Ericsson, Toshiba and Verizon Wireless, BBC, MTV Networks, and NBC Universal.
The goal of the new open source project is to:
• Remove restrictions on use of the SWF and FLV/F4V specifications
• Publish the device porting layer APIs for Adobe Flash Player
• Publish the Adobe Flash® Cast™ protocol and the AMF protocol for robust data services
• Remove licensing fees – making next major releases of Adobe Flash Player and Adobe AIR for devices free
What this probably means is that Flash content is going to be more common in handheld devices and perhaps even in TV boxes. Wide adoption of Interactive TV is one step closer.
More specific what has been done today is that:
• The SWF file format specification is published and there is no longer a license requirement to support the Flash media format. This makes it possible to write software that support Flash on any devices without paying royalty to Adobe. You can download the Flash specification today from here
• The FLV/F4v specification is published and you can download it from here. FLV/F4V is the standard in Flash that supports Video and Audio. FLV and F4V are the de facto standard for web video today; over 75% of broadcasters who stream video on the web use these formats.
If you are a developer you can find out more about Open Screen at Adobes development page.
It is a probably a safe bet that the open screen announcement comes as a result of Microsofts huge success with its new Silverlight platform. Silverlight offers about the same functionality as Flash but with support of Microsofts mature Visual Studio tools and the .net language.
Flash as a open format can only mean good things for the future of interactive video and is really interesting in the light of W3Cs work on a video extension for the html standard.
