12 Golden Rules for shooting in MOVIEtube

1. Perform a Gate check frequently

Check for dust and dirt on the filter behind the film lens inside the MOVIEtube. Use a lens brush and/ or an air

duster. Don’t scratch on the surface. Do it in clean environment. Confirm it by panning over bright background, like a

white card, will watching the image on the Viewfinder or Monitor

2. Watch T-stop on Film lens

The film lens shouldn’t be closed more than T=3.0. Best results can be achieved with open aperture on high speed

lenses (T=1.3) Notice that the more open the film lens, the less depth of field you will get.

3. Watch out for grain

Check each shot for grain. If you are filming with white and bright background and doing slow Camera movements

with T-Stop down at 3.0, the grain of the Filmscreen may become visible. In that case fully open the aperture or

avoid the bright background or the movement.

4. Zooming Gate.

Since zooming closer than the S-35mm gate will capture a closer area the grain will slightly increase. While filming

with movements (pan, tilt, travel…) fully open the aperture on your high speed lenses to T=1.3. Also notice that

zooming too close will close down the docking cameras aperture even more and you’ll loose overall sensitivity.

5. Check for Gate-Vignetation

Make sure zoom is set to manual and your Docking Cameras zoom ring is fixed with tape at focal length 25mm on

Sony HDV-Z1/ FX1. Frequently check if everything is still as it should be. Important: Check for vignetation with an

underscan broadcast viewfinder (MOVIEtube ST) or with a control monitor set to underscan mode.

6. Docking Camera is set to infinity focus

Make sure, the docking camera’s focus is set to infinity by pressing the infinity button. An infinity symbol will appear

in the docking cameras viewfinder. This will set the back focal length of the docking camera to the right amount.

Switch focus to manual and tape the focus ring.

7. Docking Camera image stabilizer turned off

To avoid the gate shifting into your image, image stabilizers like Steady-Shot or IOS have to be switched off.

8. Docking Camera sensitivity

To shoot with the highest possible sensitivity, open the Iris completely. Consider shooting with shutter speed 1/25 for

cinematically look and increasing the sensitivity by 1 Stop. Also 6db gain will raise 1 Stop. HD Video can handle high

gain, due to it’s high resolution. Even 12db looks very good. Remember shooting with celluloid? A 800 ASA film has

a lot of grain and it looks good. Don’t be afraid to use gain, check it out. Use it as a tool, like choosing different film

sensitivity.

9. Progressive 25p, Cine Gama & other settings

Progressive mode (25 full frames/ sec) can support the film look. Nevertheless it’s lowering the overall sensitivity of

your system. In that case better use 1/25 shutter interlaced and do the rest in postproduction. Since the MOVIEtube

Filmscreen is design to achieve film look with video, the image has a warm film-like, not to colourful appearance.

Check Cine Gama and other film presets on your docking camera with MOVIEtube. You might not need it. Also

check the colour temperature of your image; sometimes you may do a white balance.

10. Confirm the record turned on

Don’t forget to start the docking camera by pressing the record button. If possible establish a voice command like

“Speed” or “Running” to avoid shooting without recording.

11. Grey Filters

If you have to deal with high light energy while shooting exteriors, use the docking cameras build in grey filters. Don’t

stop the film lens down more than T=3.0. To prevent seeing any dust on the outside of the ocular and a vertical black

line from the prism, don’t close the aperture of the docking camera more than f3.0-4.0. Use “real” grey filters in a

Mattebox in front of your film lens, if the build in grey filters is not enough. For shooting documentaries, you may

need auto iris. Just limit the auto iris in the menu to not closer than f4.0.

12. Only use tested Equipment.

Before shooting your first takes test your equipment like docking camera, lenses, matteboxes, filters, follow focus.

Especially check the lenses for overall sharpness/ quality and for breathing (little zooming while changing focus).

Wider lenses are softer than long lenses above F40mm and tend to dark corners. Test Photo lenses, especial zoom

lenses for holding focus while zooming. Also if a lens causes vigneting it may be a 35mm regular gate lens only, or

the lens is not centred properly anymore (old, damaged etc.) In that case just slightly zoom the gate. 16m lenses

may work, but are not recommended. Lenses which measures more than 32mm from the bayonet flange to the last

lens element are not recommended. Attention: The may crash the protection filter. Zoom lenses with the iris

diaphragm near the bayonet flange, such as Cooke T3.0 18-100, T3.9 25-250 and T3.1 20-100, are not supported.
