Now that digital broadcasting service areas are expanding, and with the appearance of high-definition content on Blu-ray and HD DVD media, there is a strong demand for high definition content production.

In no time at all, formats for HD recording have multiplied. Although the mainstream format for delivery of commercial broadcasting is HDCAM, an infrastructure to accommodate HDCAM-SR is also gradually coming into mainstream.
5 Multi-format conversion options The VC-300HD enables conversion between many all of the formats currently used in video production. It is a multi-format converter. Four connector types provide different data sources and destinations: IEEE1394, analog component, SDI, and DVI-I.
What does format conversion actually involve with the VC series? It’s so simple that almost anyone who has operated video equipment can do it just by looking at the panel and selecting the settings. For instance, let’s see how HDV content is converted and output to other formats.
So, let’s see what kinds of things you can do with PROCESSING. When you press the button, you can cycle through five parameters - Scaling Type, Out Zoom, Audio Delay Time, Sync Source, and TC Generate - and select settings for each. Scaling Type lets you set the aspect ratio.
Although the VC-300HD is capable of diverse format conversions, the video quality is not compromised. Examine these frequently used resolutions in same-sized format conversion, down conversion and up conversion. These samples were converted via two-way connection between i.

The VC-300HD has functions that make it considerably more than just a simple format converter. Among the parameters you can access via the MENU button, you will find parameters related to video processing. For example, you can accent converted video with additional corrections and trimming.

Though he is not a celebrity, image creator Shinji Kobukata is well known in the industry as a major player behind the scenes. (Photo 1) Among his numerous productions are many promotion videos for artists belonging to a Japanese major label. He has also had a major hand in editing and directing the opening titles of Japanese TV shows.
positioning, when you magnify the picture. Do you often use magnify? In many cases, commercial films are shot, captured to HD with telecine, and finished with SD. If you have it in HD, you can pan and zoom in SD. So, it’s great that you can magnify the picture and shift the frame a bit.
The idea was for the VC-300HD to be able to deal with most of the popular formats at present. So why did they want to have a go at perfecting the huge number of conversion patterns other manufacturers weren’t interested in? Let's take a look at initial product concept and the technical backbone.
the cooperation of people in the industry. We had to get hold of technical standards, use our connections with chip manufacturers, and collaborate with camera manufacturers. I suppose you could say that we studied pretty much 24/7. When it comes to imaging devices, I think Roland makes good use of analog technology.
So, how does the VC-300HD fit into the work done in a studio? Below you can see some of the concrete advantages it offers in typical systems. ■ Figure 1. Non-Linear Editing System Non-linear HD editing has just about reached a level where it can realistically cope with native format HDV and DVCPROHD.
there is often a need for so-called line recording. Simple video switchers do not usually have DV and HDV outputs. If you want to output in these formats, the VC-300HD is your only option.
