In an effort to make it easier to transport their videos, students sometimes burn their clips to a DVD. There is nothing wrong with doing this
as long as the original file(s) are not modified in the process
. Unfortunately, instead of simply copying the file(s) to the disc (as they should) to make a " data DVD," some individuals unwittingly use a DVD authoring program to create " video DVDs" that can be played in a garden variety DVD player. In doing so, the original video file is unnecessarily converted to another (non-edTPA compatible) file format and, if it has a long enough playing time, also broken into smaller segments.
Figure 13 , below, shows the structure of a (very short) video DVD created by a typical DVD authoring program. Note that the original video used to make the DVD has a playing time of only 6 minutes and 20 seconds. If we were to open and explore the disc, we would find a folder named " VIDEO_TS " at the root level. (We need not be concerned with any other folders that might be present.) If we opened the VIDEO_TS folder, we would find a number of files with different extensions. The files we are interested in have names ending in "
.VOB
." More specifically, we are only interested in those
.VOB files that have
numerals
in their names. (For our purposes, we can safely ignore the file named " VIDEO_TS.VOB " as it does not contain any useful information.) These are the clips we need to join together in Shotcut to make a single (composite) video that can be easily edited. Since the original video has a relatively short playing time, the DVD authoring software did not break it into multiple clips. Therefore, there is no need to stitch multiple
.VOB files together in this instance. Instead, all we need to do is open the (single) video file named " VTS_01_1.VOB " in Shotcut, perform any necessary editing operations, and Export
the resulting file to an edTPA compatible format.

Figure 21:
The image on the left shows all of the disk drives on my computer, including the
video DVD in Drive F that was created in a DVD authoring program. The center image shows what we would see if we were to open Drive F (i.e., a folder named " VIDEO_TS "). The rightmost image shows the contents of the VIDEO_TS folder, including the (single) file named " VTS_01_1.VOB " which contains all 6 minutes and 20 seconds of the original program material we want to extract from the disc.

Figure 14
, below, shows the structure of another (much longer) video DVD created with the same authoring program that was used to make the
video DVD in Figure 13
. This time, however, the original video file used to make the DVD has a much longer playing time of 58 minutes and 0 seconds. If we were to open and explore the disc, we would find the same " VIDEO_TS " folder at the root level. If we opened the VIDEO_TS folder, this time we would find several
.VOB files with numerals in their names (in addition to the file named " VIDEO_TS.VOB
," which we can again safely ignore). In this situation, we would need to first use Shotcut to stitch together all four of the remaining
.VOB files into a single (composite) video before we can perform any editing operations, and then export the resulting file to an edTPA compatible format.

The image on the left shows all of the disk drives on my computer, including the
video DVD in Drive F that was created in a DVD authoring program. The center image shows what we would see if we were to open Drive F (i.e., a folder named " VIDEO_TS "). The rightmost image shows the contents of the VIDEO_TS folder, including the (four) files named " VTS_01_1.VOB
," " VTS_01_2.VOB
," " VTS_01_3.VOB
," and " VTS_01_4.VOB " which contain all 58 minutes and 0 seconds of the original program material we want to extract from the disc.
