2. We note that your Data Availability Statement is currently as follows: [All relevant data are within the manuscript and its Supporting Information files.]

Please confirm at this time whether or not your submission contains all raw data required to replicate the results of your study. Authors must share the “minimal data set” for their submission. PLOS defines the minimal data set to consist of the data required to replicate all study findings reported in the article, as well as related metadata and methods (https://journals.plos.org/plosone/s/data-availability#loc-minimal-data-set-definition).

For example, authors should submit the following data:

- The values behind the means, standard deviations and other measures reported;

- The values used to build graphs;

- The points extracted from images for analysis.

Authors do not need to submit their entire data set if only a portion of the data was used in the reported study.

If your submission does not contain these data, please either upload them as Supporting Information files or deposit them to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. For a list of recommended repositories, please see https://journals.plos.org/plosone/s/recommended-repositories.

If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially sensitive information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., an ethics committee). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent. If data are owned by a third party, please indicate how others may request data access.

3. Your ethics statement should only appear in the Methods section of your manuscript. If your ethics statement is written in any section besides the Methods, please move it to the Methods section and delete it from any other section. Please ensure that your ethics statement is included in your manuscript, as the ethics statement entered into the online submission form will not be published alongside your manuscript.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The authors created a setup for evaluating the detection threshold of spatio-temporal artefacts in movies.

and developed a mathematical model to predict those threshold. Furthermore, they conducted a comprehensive

study to collect data, which in turn was used to test the model. Finally, the results were compared to existing

models.

This is really an impressive piece of work and I would like to congratulate the authors to it!

Accordingly, I only have some minor comments:

line 73: reference Cecchi [2018] is missing

line 118 - 155: These paragraph my better fit into the discussion section

line 185: Why were especially these brightness values chosen?

line 335: Table reference missing (??)

Reviewer #2: The summary of the research and overall impression is good, however, there is a lot of scope for improvement in the article for a better understanding of the reader. The strength of the article is the success in creating the model as expected, somewhere the methodology has been made complex by connecting it to the introduction part. This part has to be reworked majorly in the current article.

The authors have made a good start in the abstract and introduction part of the article, however, in comparing the research question to the previously published article, the results of the current study have also been discussed.

Figure 1 to 5 requires citation and repositioning in the text of the article.

Line 67, figure 6 needs to be repositioned. Line 75-80 require a reframing of the sentence for a better understanding of the reader. Line 117, the same word has been repeated?

While the study appears to be good, I advise the authors to rework the methodology part of the study, giving better clarity for the current work being published.

Needs clarification on what basis the sample size for both the 1st and 2nd experiments was decided.

The methodology followed for the comparison of the model needs an explanation of the procedure/methods.

Values excluded from the study are missing in the result part, although has been discussed in the discussion part with justification.

Points in lines 295-297 can be a part of the discussion.

Line 363, is that Table 1? In the content, it has been written as table 2, but there is no table 2 found in the present article.

Table 1, representation of data in comparison to other models, PLCC need to be written as Pearson Linear Correlation Coefficient

Discussion can be elaborated, by moving some of the points from the previous parts of the article. Authors should have a comparison of the current model with the previous ones in the discussion part as this is not one of the main objectives as per the title.

Limitations of the study can be discussed.

Full data sheet access has not been attached to the article.

The reference style has to be reworked as there is a discrepancy in the list of references.
