Blackmagic Design started the uncompressed video revolution in broadcast, and it’s now become the standard way to work for thousands of people worldwide. HDMI cameras can now be used for uncompressed editing with professional results.

Uncompressed Video

Formats such as HDV and DV use video compression for smaller and easier to manage files, however this sacrifices image quality, and in the case of HDV you don't even get full resolution 1920 x 1080 HDTV video. That means HDV is not really HD! Uncompressed video capture with perfect quality video is now easy thanks to modern and fast computer hard disks. Uncompressed video won’t suffer from generation loss and always looks amazingly clean and sharp. Uncompressed video also renders faster as you don’t waste CPU time with video compression. Now 100% of your CPU time can be used rendering your effects!

Full Resolution

Intensity uses full resolution HDTV, which is a massive 1920 x 1080 pixels for every video frame. HDV only uses 1440 pixels wide due to the limitations of the small cassette tapes used and the FireWire speeds build into the cameras. However the newer cameras being released, such as the Sony HDR-HC3 have built-in HDMI video output which allow access to the raw uncompressed video from the CCD directly. That provides incredible quality. If you're capturing off HDV tape, you can still enjoy editing video in full resolution, so your graphics and effects look sharp because only uncompressed video eliminates the horizontal scaling that’s required when rendering HDV footage with graphics and effects.

Uncompressed or Compressed Video

HDV and DV also use heavy compression. With HDV, the compression is time based which loads up the system CPU as the editing software reassembles the video just to display each frame in the video. With Intensity you're working in uncompressed, so all CPU time is free for real time effects and the system feels snappy and fast to use. Because uncompressed video in HD requires a fast disk array, to save cost you can also choose compressed video that’s higher quality than HDV. For example you can use DV 100 codec on Mac OS X™ which is 4 times better quality than HDV, or on Windows™ you can choose our new full resolution JPEG codec.

Higher Color Resolution

HDMI doesn't use compression so you can record video without video compression, or choose a better compression more compatible with the work you're doing. HDV and DV are limited to 4:1:1 color sampling, so you only get 1-red and 1-blue video pixel for every 4 pixels in your image. This blurs color and causes serious color bleed on deep colors and destroys the crispness of your images. HDMI uses 4:2:2 video which has twice the color resolution, so your video won’t suffer soft and smeared color.
