Inspection of image quality and co-registration quality.** Movies available online (https://osf.io/tg5dw/, https://osf.io/g86ep/, https://osf.io/s7b2a/). Three videos are provided. One video cycles between the T1, T2, and EPI volumes, another cycles between the T2 and SWI volumes, and the third cycles between the T1 and TOF volumes. All volumes have been transformed to a common anatomical space (set by the T1 volume) in the course of data pre-processing. **Supplementary Video 2. Inspection of cortical surfaces.** Movies available online (https://osf.io/zyb3t/; see files named subj{01–08}_{axial,coronal,sagittal}.mp4). These videos show the FreeSurfer cortical surface reconstructions superimposed on the T1 volume. Left hemisphere white and pial surfaces are colored blue and cyan, respectively; right hemisphere white and pial surfaces are colored red and yellow, respectively. Blue voxels indicate locations that have been judged to have surface imperfections. **Supplementary Video 3. Inspection of fsaverage alignment.** Movie available online (https://osf.io/gh5bs/). This video cycles through (i) the binarized curvature of each of the NSD subjects mapped via nearest-neighbor interpolation to fsaverage, (ii) the average of this binarized curvature across subjects, and (iii) the fsaverage binarized curvature. The video is useful for assessing the quality of the folding-based alignment performed by FreeSurfer. **Supplementary Video 4. Inspection of MNI alignment.** Movie available online (https://osf.io/p3zqm/). This video cycles through the T1 volumes of the NSD subjects after nonlinear warping to MNI space and the MNI template volume. The video is useful for assessing the quality of the nonlinear volume-based alignment. **Supplementary Video 5. Inspection of raw and pre-processed EPI volumes.** Movies available online (https://osf.io/zyb3t/ ; see files named subj{01–08}_nsd10_run06_{raw,pp}.mp4). These videos quickly scroll through all EPI volumes in a sample run. This is useful for assessing quality and stability of the functional imaging. **Supplementary Video 6. Inspection of mean EPI across scan sessions (volume visualization).** Movie available online (https://osf.io/ydf9j/). Each frame shows the mean EPI volume from a single scan session (1-mm data preparation). Note that session 0 corresponds to the prffloc scan session and the last two scan sessions from each subject correspond to the nsdsynthetic and nsdimagery scan sessions. This video is useful for assessing overall image quality and the stability of functional imaging across scan sessions. For quantitative analysis, see Supplementary Figure 5. **Supplementary Video 7. Inspection of mean EPI across scan sessions (surface visualization).** Movie available online (https://osf.io/ytjk4/). This is similar in spirit to Supplementary Video 6, except that the mean EPI volumes have been projected onto each subject's cortical surface and then transferred to the fsaverage surface. **Supplementary Video 8. Inspection of BOLD signal strength across scan sessions (volume visualization).** Movie available online (https://osf.io/kwxta/). Each frame shows the amount of variance explained by the ON-OFF GLM model (1-mm data preparation; fixed color range). This video is useful for assessing the overall strength and stability of BOLD responses in the NSD dataset. **Supplementary Video 9. Inspection of BOLD signal strength across scan sessions (surface visualization).** Movie available online (https://osf.io/gu9wx/). This is similar in spirit to Supplementary Video 8, except that the variance explained volumes have been projected onto each subject's cortical surface and then transferred to the fsaverage surface. **Supplementary Video 10. Inflated surface visualization of noise ceilings.** Movie available online (https://osf.io/z3wxn/). This video shows the group-average b3 noise ceiling (see Figure 5F) on a rotating, inflated fsaverage surface. Values below 15% are thresholded away in order to show the underlying curvature. This video is useful for identifying brain regions whose activity is strongly related to the sensory content presented in the NSD experiment.
