Create a project
After you have logged in, you will get to the project overview. You can have a look at the demo project or start directly yourself:

- Click on “New project”.
- Enter a title.
- Set the language for the project. This should be the language that is spoken most often in the video.
- Optional (tip from an author): Leave notes for yourself and your team. Notes are displayed on the right in the project overview and in the editor. For example, you can add links to other documents and access them at any time.
- Finally, click on “Create project”.
You will now be taken to the project overview. In the upper right corner you will find a checklist. It guides you through your project and always shows you what you have to do next.
Upload a video
Once you have created a new project, you can upload a video.

- Click on “New video” in the project overview.
- Select your video.
- If your video has a burnt-in timecode that differs from 00:00:00.00, please enter it in the “Timecode Offset” field. The timecodes will then be automatically adjusted in your manuscript.
- The video will now be uploaded. The progress bar will gradually turn green. Depending on your internet connection and the size of your film, this can take several minutes.
- Wait until the upload is complete. Then click on “Save”.
- After a successful upload, the video will be analysed. Depending on the length of the video, this can take many minutes. Tip from an author: For longer videos, it's best to take a coffee break – or upload the video the night before, then everything will be initialised the next morning, and you can get started.
- In the checklist on the right, you will see a progress bar. As soon as the analysis is complete, your browser reloads the project overview and a screenshot of the video appears.
Suitable video formats
Please prepare your video files to avoid problems during initialisation. We recommend the following video codec and settings:
- .MP4 / .M4V
- H264, 720p, max. 6MBit/s
- AAC (stereo), max. 320kBit/s
In many cases, your clients can already provide you with the material in the correct format. The best thing to do is to ask them.
If this is not possible, you can do the conversion yourself. For example, you can use the free programme HandBrake. You can use it to convert your video into the recommended format. Select the preset “Very Fast 720p30” or “Very Fast 576p25”. Tip: YouTube is full of good tutorials on this topic.
Please note that your video may not exceed 3 GB when uploaded.
With the above settings, however, you should rarely reach this limit.
Create a document

Once you have uploaded a video and the analysis has been completed, you can create a document.
- Click on “New document”.
- Enter a title.
- Select the language for the audio description.
- Optional: Enter a note. It will be displayed in the project overview next to the title of the document.
- Set the default voice for your document. New texts are automatically read out with this voice. However, you can change it at any time.
- Set the default speed of the voice. Tip: It is best to leave the voice set to normal at first and then adjust the speed individually for each text later.
- In the “Test” box, you can enter a short text and play it back to get an impression of the currently selected standard voice.
- Optional: You can upload an existing document and import the texts it contains. Details about the importer can be found under Import Document.
- Click on “Create”. You will then be taken to the editor.
Create a text

- Play the video up to the point where you want to add a description.
- Click on the “plus icon” in the timeline at the bottom left, or press the ENTER key.
- A new text field appears on the right side of the editor, the field “Dialogue details” is focused.
- Optional: Add dialogue information – or go directly to the next field by pressing TAB.
- Now write your text. Finally, press ESC. The focus now jumps back to the timeline and a blue bar appears. It represents the speech output and shows you how long it takes to read out your text.
Tip: Check out our keyboard shortcuts to get more speed when writing.
Listen to the description
Thanks to text-to-speech technology, you can listen to your audio description right away.
- Without original sound: Click on the “Play” icon at the bottom right below the text field to hear the current text read aloud.
- With original sound: Navigate to the desired point in the video on the timeline and play it. You will now hear a realistic preview of your audio description and immediately notice whether it fits the video at this point.
Adjusting the speed of speech
You can adjust the speed of the voice at each text block. There are 5 predefined settings:
- Normal
- Fast
- Very Fast
- Experimental (+50 %)
- Experimental (+100 %)
Changes in speed are also automatically visible on the blue bar in the timeline.
Languages and voices

If your language is not listed, please email us. We will then see if we can add it.
Exporting documents
There are two ways to export a document – once via the list of documents in the project overview, and once directly in the editor.

- Open the submenu (3 dots).
- Select “Export document”.
- Determine whether the “time code offset” should be taken into account.
- Check the “frames per second setting”. The selection determines if/how the frames are displayed in the timecode.
- Select a “Document Type”.
- Optional: Depending on the document type, you can now adjust the timecode format.
Export formats / document types
Currently, we support the following text export formats.
- SubRip (.srt)
- WebVTT (.vtt)
- CSV (.csv)
- Word Document (.docx)
- TTML2 (.ttml)
- Our own document format (.adc)
Other formats are available on request. Please contact our support team.
Audio export formats
Currently, we support the following audio formats.
Create a backup copy
Our app automatically saves every text change in your document on the server. We also recommend that you regularly back up your work. With the help of a backup copy, you can later restore documents – e.g. from already completed/deleted projects (via “Import document”).
Proceed as follows:
- Open the submenu (3 dots) at the bottom right of the editor.
- Select “Save backup copy”.
- Your browser will automatically download an .ADC file.
It is best to get into the habit of making a copy at the end of each day.
Important! Please only use the .ADC as a backup copy. The other formats available for export (e.g. .DOCX) may not contain all the necessary data (such as the voice used for reading aloud).
Delete project
The last step: make room for something new, delete your project 😉 Go to the project overview.

- Go to the project overview.
- Open the submenu (3 dots) to the right of the project title.
- Select “Delete”.
- You will get an overview of all data that will be deleted.
- Click “Delete” again and confirm the security prompt.
