This page offers a tour of EDIT2000. If you have questions to this guide or other requests after reading this guide please contact us.
This user guide is based on the 0.2.1.1 version of EDIT2000, so if you are using a different version then some of the screenshots may not look exactly the same, but the main points should still be applicable.
The input screen presents the user with three simple steps to follow in order to complete the input process. These steps are
- input edl data
- choose format
- choose permalink
Input edl data
For the first step there are two choices, in the picture below these are marked with 1a) and 1b). You can either:
- 1a): input an edl file by selecting a file on your local computer using the "Browse ..." button ("Bla gjennom ..." in the picture), or
- 1b): you can paste (or write) text in edl format into the textarea.
Other than being two different ways of providing edl data, there is no difference in the behaviour by EDIT2000 between the two input options. There are two input possibilities only because of historical reasons and for user convenience.
If you have no edl file, but would like to test EDIT2000, you can paste edl data into the textarea by selecting an example in the drop-down menu immediate below the textarea. In the picture the drop-down menu is displayed with the value "[select]".

Step two is to select the format in which EDIT2000 will display the analysis results. There are currently two formats: html and xml.
- html: This is the normal webpage format, i.e., the results of the analysis appear as a regular webpage in your web browser. This format is good for human consumption.
- xml: This is the raw data used as source for the formatting of the html format. It contains all information from the edl analysis and is not intended for humans directly, but for further digestion by computer software. This format does not contain visual effects or diagrams. Even though it is not a format for humans, your web browser should be able to open this format just fine.
Sceenshot: format and permalink choices, and submit button
A permalink is a url that stays persistent while offering the same information. This is useful if you want to share the analysis results to others by sending them just a link. You may share results in all formats.
If you do want to share your results in this way you need to choose the permalink option. Sharing the results through the use of an url without using a permalink won't work since the edl file and your other inputs are in this case only stored in non-persistent memory. Choosing permalink on the other hand stores your edl data on the server, meaning that it will be available later, but also that you shouldn't store data that is strictly private. Although we will not make public any permalink to a user submitted file without their consent, this is no guarantee that it will not be picked up by someone and made available to others.
If you want your results stored on a permalink, then tick the box behind "want permalink" in step 3). If you do not want a permalink, then just leave it un-ticked.
The permalink is on the format
[EDIT2000 domain]/[EDIT2000 version]/year/month/day/timecode/filecode/format/
You can easily change the display format or the EDIT2000 version to use for your results by changing the format part of the URL. As an example, if you want to change the format from, e.g.,
xml and you have generated the permalink
then just change the last part
and you'll get the xml format. If you want to change the EDIT2000 to a different version then change
/0.2.0/ to, e.g.,
/0.2.1.1/. If you have linked (or permalinked) to an older version than is currently available a noticable link will inform you that a newer version is available and give you the link to view the same page in the newest version.
This section explains the output results from EDIT2000 in the html format. There is currently no explanation of the xml format.
The example used in the screenshots below and referenced to in the text is example file no. 2. It is available at the following permalink:
The result screen of an edl analysis is divided into four parts. They are
- summary of the edl file,
- overview of reels,
- summary of every reel and
- listing of all shots
edl file summary
The edl file summary displays the title contained in the edl file in the heading:
Edit decision summary for EXAMPLE_EDL_AMODE_3_EDIT2000
Further it contains a count of the number of shots found in the edl file:
No. of shots 96
and a table listing
- the average shot length (ASL),
- the standard deviation,
- the median shot length,
- the sum of all shot lengths,
- the minimum shot length with a link to the listing of this/these shot(s) and
- the maximum shot length with links.
The average shot length, standard deviation and median shot length are all statistical measurments. Click the following links to learn more:
The table lists all these lengths as both in seconds, number of frames and timecode. This calculation is based on the frame code mode given in the edl file.

This section compares the ASL of the analysed EDL file against ASLs of films in the cinemetrics database. This database contains lots of statistics and metadata about films. Clicking on the title of the films will take you to cinemetrics page on this film.

Diagram: Edit length
The diagram shows three graphs. The y-axis shows shot lengths in seconds and the x-axis represents shots in the sequence given in the edl file.
- The blue graph is the function of accumulated shot lengths over shots in the edl file. The height of the bar for a shot represents the duration of all the shots up till and including the given shot.
- The green graph is the function of shot lengths over shots. The height of the bar for a shot represents the duration of the shot.
- The yellow graph is the function of shot length differences over shots. The height of the bar represents the change in the shot length from the previous shot to the current.
Note: The green graph represents the derivative function of the blue function. The yellow graph represents the derivative of the green function, and thus the second derivative of the blue graph. For more information about derivatives read:
Sceenshot: Diagram of edits lengths of EXAMPLE_EDL_AMODE_3_EDIT2000.
Diagram: Shot lengths
The first of the shot length diagrams shows only the second and green graph of the three graphs in the diagram above, namely the function of shot lengths over shots. In addition there are vertical lines marking the values for minimum shot length, median shot length, standard deviation, average shot length (ASL) and maximum shot length. The standard deviation is marked σ and diffcult to spot in the diagram as it is behind the median label.

The second diagram is the same as the previous one, but includes also the yellow and third graph.

Diagram: Number of shot lengths
This diagram shows how many shots there are within different shot length durations. The heigth of the bars represents the number of shots of the duration indicated by the value on the x-axis. This diagram is a similar measurement as the mode value for a value set. For more information read:

Overview of reels
The overview of reels section lists all reels in the edl file with the following data:
- the number of shots in the edl file for this reel,
- the duration of these shots,
- the average duration of these shots, i.e., ASL per reel,
- the median duration of these shots and
- the start value of the first shot in the reel.
The reel names are hyperlinked to the summary of each reel, see next section. Below the table the mounting sequence and re-mounting sequence is given. Both sequences are listed with reel name and the shot name for which the reel is mounted or re-mounted. The mounting sequence lists the sequence in which the reels need to be ordered to give the sequence of shots in the edl file. Reels marked by an asteriks indicated that the reel is re-mounted, i.e., that the reel appears somewhere earlier in the list -- that the reel has already been mounted. The re-mounting sequence lists the order in which reels are re-mounted. This is the list of all the reels marked with an asteriks in the mounting sequence.

For each reel a summary of the same information as in the edl file summary is given. See #edlfilesummary on this page for more information.
In addition a hyperlinked list of the shots which appears on this reel is displayed:
Shot no's: 001, 002, 003, 004, 005, 006, 007

The report concludes with the listing of the all the shots in the edl file as EDIT2000 has read them. Much in the table is just a re-listing of the input data given in the edl file and is provided such that the user can check if everything is ok. In addition the calculated difference from in and out of source and record is listed in the columns source diff. and record diff., respectively. The column record dur. gives the accumulated shot length up to and including the given shot. The value in the record in is coloured red if it is different than the value in the previous shot's record out value. The value in the record diff. is coloured red if it is different than the source diff.
