General Aside from the codec and frame size, the most important factor in determining the quality of the finished product when rendering video is bitrate.
The term bitrate refers to the number of bits per second used to encode a given clip. Just as the quality of a still image is measured in resolution, the quality of a video file is measured by the bitrate.
For video destined for the web, you don’t want to encode with the bitrate set too high for several reasons:
1. You will make your viewers wait unnecessarily long before they can start viewing your video.
2. Higher bitrate videos put an extra strain on your server and will cost you more money in extra bandwidth.
3. Older computers will have a hard time decoding very high bitrate codecs in real time, leading to dropped frames and jerky appearing motion.
4. Uploading will be slower.
5. You’ll use up unnecessary room on your server and local drives.
On the other hand, you don’t want to encode video with bitrate too low either otherwise the visual quality will suffer – there will be pixelization and blockiness, especially in any areas with motion.
Let’s Get Progressive
“Progressive download” means, as soon as your viewers click to view a particular video, the video starts downloading to a hidden cache file on the users machine.
As soon as enough of the video has downloaded to provide the user with an uninterrupted viewing experience, the video begins playing (as long as it’s set to: autoplay = “true”).
With a video that is encoded at a lower bitrate than the total bandwidth of the connection between the video server and the viewer, the video will start playing within a second or two, and continue without stopping. This is obviously the goal to aspire to for most purposes.
Fortunately, choosing the best bitrate|best bitrate for video to achieve this goal while retaining visual fidelity is no longer just a matter of luck.
The bitrate calculator|bit rate calculator|video bitrate calculator in DV Kitchen will give you the video bitrate|bitrate that satisfies whatever criteria you set.

General Web development although very flexible and dynamic can follow the time-honed and tested methods used in systems development. Here we have identified which phases are applicable and added those are that unique to the esoteric world of the web.
Note: All throughout this document, the words web sites, web applications, web-based applications and intranet/extranets will be used interchangeably.
1. Analysis
This is the phase that most of the higher management and the ROI-concerned folks do not fully appreciate since there is no tangible output in this stage. The analysis phase is very vital as this is when you answer the tough questions: How will the web application help the present system? How is it going to help the business? Equally important is the question: How will the website complement or be integrated into the current or existing system?
Analyzing the pros and cons, setbacks and pay-offs of the website need not be too time-consuming and resource-intensive. Focus should be given to the identification of target audience, existing resources that can be utilized (e.g. a database, an excel file of customers, etc.) and ways that the website could be fully exhausted. For example, a client plans on publishing their product catalogue online; why not employ an online shopping cart and payment system? This way traffic to the site is fully monetized.
At the end of this stage, the team should be able to come up with complete cost-benefit analysis and the identified goals should be realistic. The analyst should consult the website designers, developers and testers to gauge the effectiveness and viability of the plan.
2. Specification Building
Preliminary specifications are drawn up to cover each and every element of the requirement. For example, if the product is an online store then the modules of the site such as the general layout, site navigation, and other dynamic parts are identified. Feature-rich projects will require various levels of consultation to assess additional business and technical requirements. This is the stage where you identify the who, what and when: what technology to use; who among the group is best suited to do the codes for each and every module; when is the expected delivery of the product.
After reviewing and approving the preliminary document, a written proposal is then presented to the client. The document should outline the scope of the project including the responsibilities, timeline and cost.
3. Website Design and Development
After the specification of the project has been identified and the proposal signed by the client, work on the web site commences. Normally, the site layout and navigation will be designed during this phase as prototype.
Two to three study designs are offered for client viewing and approval. Some client might demand to see the full functional prototype – then the team has to show them the interactivity of the site’s various features.
In most cases, the client will give suggestions and require a lot of changes on the prototype. Once a final version of the design, layout and navigation has been achieved with the client’s approval, of course, you should freeze the prototype before you start the codes.
We need a quick definition of FREEZE here. It is a method to make both parties to agree on how the web site will look like and function on the launch day.
The development team during this phase will start the database structure. All necessary information should be had from the client, such as access to test servers and database, ftp login, sample data, and images they would like displayed in the site.

General Often all of us get mystified for ideas for present giving. You need your show be enjoyed by the receiver, but perhaps you have consumed your best present ideas.
