Video Constructor
Вопрос: What are recommendations on computer hardware, where will Video Constructor be set?

The minimum systems requirements to the hardware are indicated in user's Video Constructor guide. However, as in the real projects the promoted requirements are pulled out to the productivity and reliability of the visualization systems, it is recommended to read the followings advices of choice if RAID-array, video cards, capture devices and etc. Remember also, that you can purchase the prepared videocontroller of «Bliscom», which will be answering all components requirements and will include already set Video Constructor TV edition.

Вопрос: What recommendations on the choice of RAID-array?

To choose a configuration of RAID-array you must well undestand, with which video and graphic materials it is planned to work. In the case of necessity to output one or two videofiles in standard resolution it is possible to treat without a RAID-array (or to use him exceptionally to increase a reliability). If the question is about the simultaneous reproducing of a few HD-videofiles or work with the uncompressed video, it is required to count total bitrate of all simultaneously destroyed video data, do some supply (minimum 20%-30%) and, coming from these information, to pick up the amount of hard disks, type and configuration of RAID-array. Remember that you can purchase the prepared videocontroller of «Bliscom», which will be equipped with a necessary for your case RAID-array.

Вопрос: What video cards is it recommended to use Video Constructor with?

Video Constructor works with any video cards, vehicle supporting DIRECTX 9. The hardware acceleration of video decoding is desirable also. «Bliscom» recommends to use Nvidia video cards of  eighth or ninth series (Nvidia 8800, 8600, 8500, 9600, 9500 and etc).

Вопрос: What capture cards does Video Constructor works with?

All DirectShow-compatible devices of videocapture are supported. If an image from the device of capture can be represented in such programs as Virtual Dub, Media Player Classic, Adobe Premier and etc, it means,  there will be no problems and in Video Constructor with him. If you need help at capture card choice, you can write us to address of support@blis.com.ua.

Вопрос: What is delay at the capture of videostream and its reflection by Video Constructor?

In the case of the «Bliscom» videocontroller's use with the proffesional cards of SDI-capture a delay makes no more than 1-2 shots, that by sight practically not remarkable. At other hardware configurations results can differ.

Вопрос: How many sources can represent Video Constructor simultaneously?

Programmatic limitations are not present, as far as the carrying capacity of disk array and power of processor will be enough for decoding of video. In the case of «Bliscom» videocontrollers use the question is about a few FULL-HD videofiles or much more sources in standard resolution.

Вопрос: Something does not work (hangs up, not represented, brakes). What to do?

Unfortunately, these information it is not enough to help you. Please, write us a letter to address of support@blis.com.ua, reporting the here following information:

Вопрос: How to use a built-in sсript language?

To use script language choose a menu of «Edit->Scenes». After it you can create scripts (macros, stages). For this purpose push the button «Add» and in the field of «Code» write the code of script. The example of code fragment with all possible commands is shown below in the field «Example». There are 8 commands, applied to the sources (layers): “preload”, “play”, “show”, “pause”, “seek”, “hide”, “stop”, “unload” and 1 global command “sleep”. In a general view every line of code looks as a choice of certain source or layer and command on implementation of certain code, for example: layer("title", "New region 1").play(); - means to «choose a layer at which the name (title) is equal "New region 1" to start reproducing of video in this layer.
After creation of code of the stage it is possible to open the dialogue box «Scenes collection» («View->Scenes collection»). Here you can look over all stages created by you and give a command on implementation to any of them.

Вопрос: I want to integrate Video Constructor (or videocontroller) with present software (or hardware). How it to do?

If the question is about a video or sound capture or reproducing – just simply connect the proper inputs and outputs of our videocontroller and your equipment. If you mean support of some new protocols or necessary inputs\outputs are absent in default «Bliscom» videocontrollers configurations – write us. As we are developers of software and videocontrollers, always there is a possibility to perform your individual order.

Вопрос: How to create a slide-show in Video Constructor TV-edition?
So, it admits we have four pictures 1.jpg, 2.jpg, 3.jpg and 4.jpg, which we want to show as a slide-show.
1). Start Video Constructor. Create new presentation.
2). Push the button “Image Layer” and add to presentation a layer with a picture 1.jpg.
3). Click on this layer by the right button, choose in the menu of "Layer Properties...", tab "Load and
Apply", check off "Set apply".
4). Repeat points 2-3 for pictures 2.jpg, 3.jpg and 4.jpg.
5). Select all  4 layers with pictures. Press "Ctrl+5" to resize to an all presentation.
6). Press "Edit->Scenes". Add the new stage (button "Add").
7). In the field "Code" write the following text:

layer( "title", "New region 1").play();
layer( "title", "New region 1").show();
sleep( "5000" );
layer( "title", "New region 1").hide();
layer( "title", "New region 1").stop();

layer( "title", "New region 2").play();
layer( "title", "New region 2").show();
sleep( "5000" );
layer( "title", "New region 2").hide();
layer( "title", "New region 2").stop();

layer( "title", "New region 3").play();
layer( "title", "New region 3").show();
sleep( "5000" );
layer( "title", "New region 3").hide();
layer( "title", "New region 3").stop();

layer( "title", "New region 4").play();
layer( "title", "New region 4").show();
sleep( "5000" );
layer( "title", "New region 4").hide();
layer( "title", "New region 4").stop();

Attention! If your layers are named not "New region N", but in another way, change the code of the stage properly.

8). Presentation is ready. Push the button "F5". Press "View->Scenes Collection". Choose the first stage. Push the button "Start". Slide-show started.
 Here are some more recommendations:
    *      For more showy you can add to every layer picture appearance and disappearing effects, for example - "Fade".
    *      There are alternative methods of creation slide-show. You can use advantage of videoeditors (Adobe Premier, Windows Movie Maker) for creation videofile from the
pictures and to use it in presentation.
    *      If you don't need an interactive presentation management, you can take advantage of the program Net Eye, in which a slide-show is done considerably more comfortable.
