If a video is said to be Rec. To make things more confusing, you have the Rec. These standards have different resolutions and different aspect ratios. Some formats have been created for video using common codecs but only allowing certain variations in things like resolution and bitrate so they can more easily be used across hardware and software platforms. Compatibility with different codecs and formats for hardware and software can still be a huge challenge.
You want to ensure that any codecs you plan on using from acquisition in production through post and onto distribution and archiving are compatible with your hardware and software before you start on your project.
You can often see things like color shifts in images when moving from one piece of software to another since they are probably not processing the image data the same way.
On a large project or one where consistency is critical, testing your workflow before you begin can you help avoid or learn how to compensate for problems like this. Keep in mind, when you compress video data, there is some data loss in the process.
Video compression applications work by looking for redundancies in a frame and maintain them frame to frame. For example, one bit of blue sky is the same as another bit of blue sky. The blue section carries through each frame. At high compression rates, this becomes obvious. An uncompressed codec stores media without compression so no quality is lost but the files are big.
A lossless codec stores media with compression and without quality loss but with minimal space savings. A lossy codec stores media with compression and quality loss. With lossy compression, the higher the compression, the smaller the file and the greater the quality loss.
Note that if your rendering for archiving, compression is not recommended. Likewise, keep your master files in the original video format. The highest quality video format is the one you originally captured. While digital files do not degrade in quality, every time they are converted, there is a loss in data.
Converting your uncompressed files directly from your camera, even into a high-quality file, does result in some loss of quality. Generally, you should edit and create versions at whatever sizes necessary. There are times when using an intermediate is preferable or a must.
Depending on the delivery format, using a lossy intermediate codec like ProRes or Matrox MPEG-2 might be worth it for the ease in workflow, despite the loss in image quality. If you do transfer between formats, remember that re-compression causes degradation. It is best to create multiple versions of your files for multiple uses. One file format you will upload to your web site, but you may choose a different format or size to email to your clients.
Then, you might save the final product in a third video format to a hard drive for projection at an event. You can rely on your editing application for a lot of the work in deciding how to compress video files.
Most consumer editing software today will have presets for various methods of distribution — such as email, YouTube or video display. Since compressing a video file can cause it to lose a lot of its image and sound quality, taking the same file and compressing it multiple times can make that loss much worse.
Most online video hosts like Vimeo and YouTube will re-compress the video you upload, so you want to make sure that you maintain as much quality as you can before it gets to them.
Ask yourself a few questions about your intended audience: Will they be watching video streaming over the internet? What kind of connection speeds? Do they have a DVD player or a Blu-ray player? A few containers have codecs that they almost always use and other containers are often used with many different codecs. This container format is one of the most commonly used formats today, especially when it comes to sharing content online. In fact, YouTube recommends uploading files in the.

Almost all newer camcorders capture high-definition video, even low-end budget models at either x pixels or x pixels at various frame rates.
Such footage will look best when viewed on an HDTV. There have also been fewer full-sized HD-models introduced because an increasing number of devices SLRs, smartphones, tablets also capture HD video. However, 4K video camcorders are appearing in the market. The major distinction between a 4K camcorder and an HD camcorder is the resolution they capture:. Some can even shoot in p—the same format used on Blu-ray discs. Only a few models record in p, an alternative HD broadcast format.
Sony dominates the camcorder market, offering a range of models across all current consumer formats. We respect your privacy. All email addresses you provide will be used just for sending this story. Sign In. Become a Member.
