The application relates to creating an MPEG file from non-temporal based compressed image data that are stored on randomly accessible storage and edited on a nonlinear video editor to create a video program (fig.1, 10). Th e editor generates information indicating the complexity of portions of image data simultaneously with storing and/or editing of the image data (fig.1, 10 ). The information is accessed to determined MPEG compression quality levels fo r groups of pictures of the image data based upon information (fig.1, 12). The groups of pictures of non-temporal based compressed image data are converted into MPEG compressed data using the respective quality levels (fig.1, 12). Also disclosed are displaying a representation including an indication of complexity of the portions; concurrently with compressing of the image data, decompressing the image data of the compressed file and playing it on a monitor to permit real time viewing of the quality of compression (fig.1, 14 ); and editing an MPEG compressed file by accessing the non-temporal based compressed image data to make changes without creating artifacts at boundari es of the portions of image data in the sequence in the MPEG file (fig.1, 12).< /SDOAB>
