Video evaluation

Modified on Mon, 19 Aug, 2024 at 1:10 PM

Video Evaluation is a type of task that presents the participant with a video to be evaluated on a scale and marked with reaction labels.


Comments per label can be activated and applied along with the minimum/maximum number of responses.



Although there are many different use cases, video evaluation is commonly used to evaluate commercials, advertisements and website design.

Set up


To create any task, you must have Administrator or Moderator access. Using one of these accesses you must go to the activity's gear menu and click on “Edit Tasks”. If you haven't yet created your first activity, you should do so before proceeding. Learn more about creating an activity here. 



1. Choose “Video evaluation” from the list of tasks.


 

 

2. Use the text box to write the question statement, instructions and any other information you deem necessary. Adjust the text formatting using the icons (bold, italics, background colors, text colors, alignment, etc).


You can supplement your assignment statement with a video, photo or file. To do this, simply click on the “Add Media” button in the top right-hand corner of the text box and upload it.


 

3. You can also change the task (question) code using the rounded field next to the task list. The code of a task is important for identifying the question in the database and also for viewing the answers on the platform. OW Voices will always place the screen “T” followed by a natural number in ascending order for the task codes. 


Remember that the answer option code cannot contain special characters, spaces or just the number 0.



4.  Choose the video to be evaluated. To upload, click on the highlighted area and choose the video from the documents on your computer. 


 
5. Define the description and Emojis of the reaction labels. Remember to choose different descriptions and Emojis for each label, so that the heat map can be read and analyzed more easily.




6. Set a maximum and minimum number of reactions to be given by the participants. Remember that the participant can use the same label more than once. 



7. Choose whether commenting by reaction is mandatory or not. Click on “Comment required” to enable it. 



8.  You can add logic and conditions to your question to direct them to another one based on the answer given in the task. Although it's not possible to generate logic and conditions based on the answers to a video assessment task, you can reference a previous task to generate jumps and conditions from it.


Default → define which task the respondent will be redirected to after answering the chosen task. Here you can add a skip or even choose “finish”. This option will only be applied if the respondent does not qualify for the other conditions specified in “If you answer”.
If you answer → add a logical condition for the flow of your activity.



9.  Defina a descrição da caixa de comentários no editor.

Gráficos e Tabelas


No menu "Relatórios", Administradores, Moderadores e Observadores poderão visualizar gráficos para todos os tipos de tarefas. Para tarefas do tipo Avaliação de imagem será gerado gráfico de bolhas indicando as reações mais utilizadas a cada segundo do vídeo e um gráfico de pizza indicando as reações mais utilizadas em todo o vídeo. 


O gráfico de bolhas contém bolhas maiores para indicar pontos no vídeo em que a etiqueta foi mais utilizada e bolhas menores para indicar pontos no vídeo em que a etiqueta foi menos utilizada. 


As tabelas posicionadas abaixo dos gráficos irão exibir a frequência das etiquetas em números absolutos e em porcentagem.
