Video-Digitizer Grabstar AV
Artikelnummer: DNT000010
User manual
1. Features
The video digitizer enables easy recording and playback of analogue video sources on an USB
storage device or a SD memory card. This means that the video digitizer can digitize content from
analogue media, such as from a video recorder or camcorder. The ability to digitize with the higher
quality S-video* signal also enables high-quality digitization results.
- Saves recordings directly to SD/SDHC memory card** (up to 128 GB),
USB stick (up to 128 GB) or external USB hard drive (up to 4 TB)
- Supports FAT32, NTFS***, exFAT***
- Works with PAL and NTSC formats
- Recording resolutions****: 720 x 576p, 720 x 480p, 640 x 480p
- Video format: MP4
- RCA connector (RCA) and S-video input with separate Y/C signal transmission
(luminance/chrominance)
- 8,9-cm-color-display (3.5") for checking/playing back the recordings
- Integrated video player can playback digitized A/V-recordings on TV
- Integrated device speakers
- 5 VDC/1 A power supply
- Auto-Stop-Function: 60/90/120/150 min
- Table and wall mounting possible
* Compared to CVBS, S-Video is based on the separate transmission of brightness signals (lu-
minance, Y) and color signals (chrominance, C) each on its own signal wire. This means that the
signals do not have to be mixed as with CVBS and filtered out on the receiver side. This reduces
interference that can occur in CVBS filtering due to the mutual influence of brightness and color
signals, and leads to more detailed and color-qualitative reproduction of the analogue media.
** SD cards with a file volume of 64 GB and above can only be used with exFAT and NTFS format.
*** MAC users should note that NTFS or exFAT is not supported by MacOS and the storage medium
will show no content if NTFS or exFAT is selected as file format. The same applies to Linux users.
Please select FAT32 as file format for formatting the storage medium.
**** Please keep in mind that higher recording resolutions are not useful because the native re-
solutions of the analogue source material are typically very low. Recordings with higher recording
resolutions do not provide better quality and usually cause significantly worse digitization results!

5. Operation
Please note:
An SD/SDHC memory card or microSD-card with SD-adapter of class 10 should be
used as a memory card to ensure trouble-free recording.
With recordings, the file names are automatically generated according to the pattern:
date+index.mp4.
Note:
The time will be reset after the power
supply has been removed – if you use the
device again, you must set the time/date
configuration again!
The optimal resolution is automatically se-
lected by the Grabstar AV and the recording
is saved in the format 720x576 or 720x480
(„Auto-Detection“). It is not possible to influ-
ence the format during auto-detection mode.
Note: Recording resolution (576p or 480p)
will automatically be choosen due to it‘s
original source.
Standard Memory: Selection of which external storage (SD card or USB storage) should be
used as the standard storage. If one of the alternatives is not available, the system automatically
switches to the available storage type.
Reset to default: Reset the device to the delivery state
Formatting: Formatting the storage medium
Firmware update: A new firmware version is going to be installed here (if available)
Software-version: The current firmware version is displayed
- After completing the settings, go back to the video preview with the „Menu“ button.
Recording function
- First check whether the video source and memory are connected
(see „Connection and commissioning“).
- Start recording with the „Rec/Stop“ button on the device. The recording time is shown
in the top on the left.
- Stop recording with the „Rec/Stop“ button on the device. Alternatively, you can use
the „Auto stop function“ option. Then the recording stops automatically after the selected
recording time.
- You can cut out unwanted content from the original recording during recording process.
To do this, briefly press the „OK“ button at the beginning of the part to be cut out, now
the recording time display flashes.
At the end of the part to be cut out, briefly press the „OK“ button again, now the
recording continues.
Signal Loss detection
The Grabstar AV is able to pause the recording
in the event of missing/faulty source signals.
The deactivation of this function means that
the recording can only be stopped after
the user has manually finished/stopped his
recording and is therefore only recommen-
ded if the source medium is in poor/faulty
condition/quality.
Playback function
- First check whether the previously used memory is connected
(see „Connection and commissioning“).
- Playback can either take place via the device itself or on a monitor/television connected
via HDMI. If a monitor is connected, the display of the Grabstar AV remains switched off
during video output.
- First press the „Mode“ button twice to switch to playback mode. A blue triangle now
appears as a label in the top on the left.
- Select the desired file from the list displayed and start playback with the „OK“ button.
- You can adjust the playback volume with the arrow keys q and p.
- With the arrow keys t and u you can accelerate the playback forwards and backwards
(„fast-forward/rewind“). Stop playback with „OK“.
6. Firmware-Update
- Copy the update file into the basic directory of an SD memory card or USB memory,
which you connect to the Grabstar AV.
- Switch on the device: If you have copied the firmware to an SD card, the update window
appears automatically. For USB storage, manually select the firmware update option in
the main menu and start the update from there.
- Start by choosing „Confirm“.
- Do not interrupt the power supply or the connection to the data storage device during
the update process.
- After a successful update, the device automatically restarts.
7. Notes on Errors
No picture appears on on the display:
- Check the connection and output of the video source.
- The display remains switched off when a screen is connected to the HDMI output.
Device does not recognize storage device
- The storage device may not be formatted with FAT32, NTFS or exFAT, e.g. if it was
previously used in a digital camera. Format such memory cards with a PC and a
compatible file system. You can format a new memory card via the internal menu
„format“.
For formatting high-capacity USB hard drives, we recommend using the freeware tool
„Guiformat“ and formatting the hard drive in FAT32 format.
Mac OS users must note that the exFAT and NTFS format cannot be used.
Linux users are also affected by this, but can use various solutions and tools from the Internet.
The formats mentioned here refer to a Windows client/computer.
Image freezes when recording („freeze“)
- Press the on/off button for 10 s and the device restarts.
No sound output
- Check whether the mute function is activated and a sufficient sound level is set.
- When recording, check whether the audio lines are connected to the audio inputs.
This applies to CVBS as well as S-Video.
No files found while playing
- This can happen if files have been uploaded externally. Video files have to be in the folder
„Video“.
8. Care and Maintenance
Only clean the device with a soft, dry linen cloth. In case of heavy soiling, it may be slightly damp.
Do not clean the device with cleaning agents containing solvents! The device has to be dried
carefully with a cloth. Make sure that no humidity gets inside the device.
