Bogart SE 5 User manual

(10) Clicking on the ‘Preview’ button opens a small screen in

which the video plus the effect runs. In this way you can judge

and perhaps make corrections (for color, intensity, time, etc.)

to the effect before creating it. The running time of the preview

will correspond approximately to the time of the calculated

effect.

The duration of the preview is approximately that of the ﬁnal

version. The preview may be a little ‘jittery’ because it does not

work at the normal frame rate. This will not occur in the cre-

ated effect. A preview does not require any hard-drive space.

(11) After you have inserted an Image Processing effect and

perhaps speciﬁed its range, you can click on ‘Full Size’ (In the

Basic Edition, you do not dispose of all functions. Complete

functionality is only available in the Gold Edition) to bring up

an additional menu. In the background you see the middle

frame of the entire segment for the inserted image processing

effect (if the effect is applied on the entire scene, then you will

see the middle frame of the video scene). The video image is

superimposed by an operating panel in which you can see the

effect options (if available) on the right side. The button ‘Dis-

play’ below allows you to select from different display modes,

which can help you to check an effect more precisely. De-

pending on the selected effect, it may be useful to change the

display mode. ‘Original’ (shows the just selected new scene).

‘Compare’ halves the image, with the right screen half showing

your new scene and the left any scene that you can choose

using the ‘Choose scene’ button (below) from the scene bin.

The compare function can therefore be used to adapt the color

tone of your scene to an already present scene.

‘O+E center’, unlike ‘Orig. + Effect’, always compares the

centre part of a scene, on the left the original and on the right

together with the effect. This comparison type is suitable for

effects that appear mostly in the centre of an image.

The ‘O+E small’ display type shows you the complete origi-

nal scene compared to the effect. Both scenes are smaller

previews. However, remember you can’t see ﬁne details in this

fashion, as opposed to larger effect previews. It can be very

useful for image processing effects, comparing the original and

the effect scene with each other. ‘C centre’ has a preview style

comparable to ‘Compare’, but in this case, the centre part of

the scene is focussed on, as the most important part of the

scene is often found in the centre. For example, if you want

to apply an image processing effect such as Color Correction

in order to adapt that scene’s color tone to other scenes, a

comparison in full size is a good solution.

‘C small’ = If however, you are ﬁne working with a smaller

preview, you can switch it to small. This simply allows you to

compare the scene with the effect as a whole, yet in smaller

preview screens.

Tip: It is recommended to switch back and forth between the

different modes while working on the effects. This way, you can

experience the scene in its completeness.

Above the function ‘Display’ you see the ‘Frame’ slider with

which you can set the point in time of the long-term effect that

you want to view. You can use this button to specify the point

in time of the transition effect you want to see.

In this way you can observe the applied effect at any point in

time of the scene. The button does not have to be conﬁrmed.

You can scroll slowly through this part of the scene and view it

at the same time. Of course, you can change the effect options

as you wish and thus have the possibility of directly comparing

various colors and directions. The effect options can be set

directly in this window, while watching a real-time preview. The

selection of the sliders does not have to be conﬁrmed.

In the top left corner of the menu you will ﬁnd a button with

which you can play a small preview. This will give you the abil-

ity to see the effect of your settings, which you have had so far

to assess in a single image, in a real-time preview.

The settings made in this menu are conﬁrmed with ‘OK’ and

you are returned to the Edit menu. With ‘Cancel’ you leave the

‘Full Size’ menu without saving any changes. The arrow but-

tons serve to move the single-image menu to the top edge of

the screen.

(12) When you click on the ‘Create’ button a screen appears

in which the course of the effect can be seen as it is created.

After the creation is completed, the symbol’s outline is blue.

When you calculate an effect Bogart SE reads all individual

images from the scene in question and applies the effect to

it. The result is stored on the hard drive. This procedure takes

time and consumes hard-drive capacity. When recording data

you should always leave a small amount of hard drive capac-

ity in reserve. Depending on how often effects are used, this

should be between 2% and 10% of the video playing time.

(13) If your system supports the function ‘scene’ you can make

use of the multi-layer technique. (In the Basic Edition, there is

only a limited functionality for the creation of a scene) If you

would like to overlay several long-term effects, you at ﬁrst

insert an effect into a scene and create it. Then you convert the

scene with the inserted effect into a separate scene. To do this

you click on the ‘Scene’ button so that a window appears in

which you can select the range for the new scene. The name

of the used image processing effect appears next to ‘Name’

and is given as default name for the new scene. If desired, you

can enter another name by clicking and using the keyboard

that appears.

You also see the three options ‘Effect’, ‘Effect + scene(s)’,

and ‘Range’. If you only want to convert the effect with the

previously set range into a new scene, then click on ‘Effect’.
