AVCHD consumer purgatory

Crave blog writes about the current challenges of dealing with AVCHD footage. As a potential consumer HD camcorder buyer I acknowledge that AVCHD’s unmanageability is a shame. Even viewing shot footage is still bit complicated. The lack of wrapper and codec support in common editing suites makes matters worse. However I think people are partly missing the point. AVCHD was designed as a delivery format and consequently users should settle to annotating and cataloging the content. Continue reading ‘AVCHD consumer purgatory’

Machine-Generated Content

The Mashable blog makes a good point commenting on user-generated content (UGC). 99% of UGC is nowhere near the quality expected of professionally created content. However they recognise that by applying ‘next-generation AI and content processing algorithms’ the good bits can be found. This makes perfect sense. Repeat customer always needs an acceptable risk/reward-ratio for media services.

The user risks time, money or both. Harnessing the power of masses these risks can be minimized. Listening to popular music and watching award-winning movies minimizes the time part. However you could argue that sometimes art and even experiencing it is more about the journey than the end result. Shifting through volumes of content can be fun, especially if there is a real chance of finding something really good. The promise of social media is that by sharing this information an intelligent agent can help you and others minimize both risks.

Same concepts apply to automatically captured video also. Machine-generated content (MGC) services just increases the number of content items substantially. The workflow needs to be very well tuned. Efficient preprocessing and short media duration will help, but even then a very active community with simple and effective tools is required. Challenge is enormous, but that just makes finding the solutions interesting. 

Aesthetic science

Stephen Palmer from Berkeley gives an interesting speech on ways aesthetics of visual art is appreciated by humans. He touches on aesthetic science and neuroesthetics which are two recent fields within cognitive science. Eventually the tools created will help us to start understand how the creative mind works. When this field advances it may become even possible to create an artificial aesthetic sense. Future camcorder may include a aesthetic prosthetic, helping us mortals create techically flawless art. 

Camera reinvented

Adobe has been doing some innovative forward-thinking research for their Photoshop image editor. The idea is that photo editing becomes much more flexible if more information is stored already when picture is taken. This of course means that camera technology will need to leap forward and there will surely be use for computing power even in the future. Check out the rather amazing video from the demonstration. As the open source community has been able to produce tools like Gimp and Paint.NET it is great to see the market leader take steps to reinvent image editing. Some day we hopefully see even an After Effects version.

Golden seam carving

Recently two Israeli scientists published a screen capture video of their experimental image resizing tool in action. Tool uses a seam carving algorithm to identify and delete areas of the picture most unlikely to include important information. The demonstration has rightfully gained quite a lot of attention. Inspirational video has already spawned multiple different tools, plugins and web services that attempt to reproduce the same functionality on different platforms. While seam carving may even in itself be revolutionary it is also a gateway to even more impressive new tools. One such idea is combining the algorithm with golden section rules.

Automated shot composition

Promise of fully automated video production is achieving mesmerizing shots and sequences just by identifying, finding and positioning the cameras in a spot relevant to the task at hand. The technology is progressing at a rapid pace so this vision does not have to be lazy cameraman’s daydream anymore. Preparation and documentation is half the work and they give the best starting point for developing a smart shot composer. Continue reading ‘Automated shot composition’

Process

Processing is merely transforming raw video footage by manipulating the captured data. Adding effects, joining clips and encoding to more distributable formats are all common ways to process video. Electronic editing systems have heeded scissors and manual labor. For long dedicated hardware solutions were needed to handle processing. Real-time signal processing had to first cope with analogue video signals and then digital video at high data rates.
