Section 2. Project Day 1 Briefing Sheet

Expected Outcomes for Day 1Goal for day 1 is the creation of a complete video sequence that contains a minimum of three clips. One clip must be a chroma keyed split-screen footage and the remaining two clips must be appropriately selected from a given library of source material.

Key Tasks Project Planning: developing an appropriate strategy to meet a specific set of technical

requirements.

Chroma Keying: capturing two blue-screen clips (group task) and applying chroma keying to both of them.

Duplication of the character: combining the two chroma keyed footages into one clip where the character is duplicated in the result clip.

Technical Appraisal: selection of appropriate video sources.

Compilation of Content: building a video sequence and adding special effects to it.

Visual Sequence Requirements

Video Capture: You are required to capture two short video clips onto a miniDV tape of yourself either standing or sitting in front of the blue screen in the video studio. You will need to work with another student who can control the camera, the screen and lighting for you. The captured footages will be used to create a 20-second clip in the final sequence.

Chroma Keying: You must use the chroma keying of Premiere to remove the blue background in both your blue-screen footages. Add special effects to both footages such that they, together, show an interesting storyline when being combined using split screen technique.

Duplication of the character: You must use split screen technique to combine the two chroma keyed footages into a single clip. The character (yourself) in the two chroma keyed footages must be duplicated in the new clip. Superimpose the split-screen clip onto a static background taken from the still image library posted on the video server.

Sequence Assembling: You must assemble a video sequence that contains a minimum of three video clips. One clip must be the split screen clip that you have created and the remaining two clips must be appropriately selected from the given library on the video server. Each clip should be approximately 20 seconds duration giving a total running time for the whole sequence of approximately 1 minute.

Video Editing: Apply suitable transitions in between the three clips of your sequence. You are strongly advised NOT to add other special effects to your sequence as you will be required to add more special effects in Day 2.

Assessment criteria for Day 1All the work you submit must be produced by you working alone (except for the capture of the blue-screen footages) and within the timetabled six hours for Day 1.

For assessment you are required to;1. Complete and submit an e-log online2. Post your video sequence on the server by 17.00.

Name your video sequences after yourself. For example, day1_B_Simpson.avi.

Your progress will be monitored and assessed throughout the day with reference to your e-log plan.

Important criteria for assessment are; quality of the blue-screen footage, quality of the chroma keyed clip, choice of clips from the library, technical parameters considered during video capture, editing and clip selection from library, quality of the assembled sequence, use of special effects, and the way in which the work has been managed.

Tool The software package you are to use for this assignment is Adobe® Premiere Pro CS3®.

All your project files must be backed up regularly for final assessments and future use (Day 2 of this project).

Mini Project- Digital Video EditingRecording the evidence of your progress during Day 1

When you have completed this miniproject (both days 1 & 2) you will need to write a report describing the work you have done. It is vital therefore that you keep a record of your progress during the day. It is strongly suggested that your record should be made up of both written notes and a digital diary composed of screen shots.

Section 3. Project Day 2 Briefing SheetExpected Outcomes for Day 2

Working individually, each student must apply further editing to the sequence created in Day 1. Subtitles must be added to show where and which editing technique or special effect has been applied. Also suitable background sound needs to be integrated into the sequence. Finally, the audio-visual sequence must be encoded for distribution over the given digital broadcast platform. An intermediate goal for day 2 will be the encoded clip (with required editing fully applied and adequate subtitles and background sound added).

Key Tasks

Project Planning; developing an appropriate strategy to meet a specific set of technical requirements.

Content Editing; additional editing and subtitles. Technical Appraisal; compression strategies and technical parameters to be used.

Audio-Visual Sequence RequirementsVideo Editing

Additional editing: apply the following editing technique at least once to your sequence.o Change clip speed (apply speed change to a section of the sequence rather than the entire

sequence)o Motion keying (motion path): you may create more than one motion paths, where still images

must be used in at least one path. You are allowed to find images from the Internet or use those on the local Server. You may apply chroma keying before motion keying. This can make the moving object look more natural in the clip.

o You are encouraged to apply other editing techniques to your sequence. Marks will be given for creativity.

Subtitles: subtitles must be added to wherever an editing technique or special effect has been applied. The subtitles should state which editing technique or special effect has been applied there. Note that duration of a subtitle should match the duration of its named special effect.

Opening title: add an opening title to your sequence. Your opening title must clearly show your name and student registration number.

Audio Creation: Add suitable sound effects and background music tracks to the video sequence that you have created.

Encoding: You must use the encoding facility of Premiere Pro CS3 to generate two encoded version of the audio-visual sequence that you have created. One encoded version should be generated for broadcasting and the other for streaming to mobile devices. It is crucial that the appropriate codec and technical parameters are chosen for each encoding process (refer to the encoding exercise of the preparation day for guidance).

Assessment CriteriaAll the work you submit must be produced by you working alone (except for the capture of the blue-screen footages) and within the timetabled six hours for Day 1.For assessment you are required to;

1. Complete and submit an e-log online2. Post three video sequences to the server by 17.00.

Uncompressed: original_your_name.avi Broadcasting: bcast_your_name.xxx Online streaming: streaming_your_name.xxx

You must name your video sequences after yourself. For example, original_B_Simpson.avi. ‘xxx’ here stands for the file extension. For example, it will become ‘mpg’ when MPEG standard has been used.

Your progress will be monitored and assessed throughout the day with reference to your e-log plan.

Important criteria for assessment are; the way in which the work has been managed, the creation of motion path, the use of subtitles, the application of other editing techniques, the technical parameters and the compression strategies used for the target delivery platform.Tool

Section 4. Exercise: Importing Digital Video using Adobe® Premiere Pro CS3®

The aim of this lab exercise is to introduce you to a variety of ways in which you can import video and audio into Premiere Pro, edit the captured clips and then export a final, rendered sequence.

The PCs used for this exercise have been configured to control the capture of digital video and audio from either a SONY DVCAM tape deck or a JVC dual tape deck.

DV cameras equipped with Firewire interfaces can also be used for video capture from DV tape but are not described in this tutorial sheet. Capturing video from the lab’s s-video distribution system and importing clips into Premier is also an option.

Any standard AVI clips can be used in the following exercise.

You are strongly advised to keep your own notes in a log-book. You will find it useful when preparing coursework if you note down tips and problems you have overcome during a guided session.

Part A must be done first but then parts B and C can be done in either order.

Work as part of a group of two or three students to complete this lab tutorial.

Part A: Capturing video content on TapeThe video capturing suite contains a semi-professional quality SONY digital camera which uses the miniDV tape format along with a chroma key (blue or green) screen and two high wattage photographic quality lamps. These basic facilities can be used to capture high quality digital video material shots which may then be imported into a non-linear editing system such as Premier Pro where a range of keying effects may be applied.

1. Insert your miniDV tape into the camera. Ensure that camera is powered on into the VCR position. Press rewind on the top of the camera to make sure all new contents will be recorded from the beginning of your tape.

2. Moving the power/charge switch on the right-hand side of the camera to the CAMERA position for recording.

3. Switch on both lamps and let them warm up for a couple of minutes, note that they can get hot and the bulbs can be easily damaged.

4. Place your subject either standing or sitting in front of the blue screen. Try to position the lamps such that the screen is evenly lit with minimum shadowing.

5. Check your focus and zoom. Record about 1 minute of footage. Press the red (record) button to start/stop a recording.

6. You can check your shots by moving the power/charge switch on the right-hand side of the camera back to the VCR position. Rewind and press play on the top of the camera to ensure that you can see your recorded footage on the camera’s LCD monitor.

Part B: Importing video from tape using Premiere Pro CS3Depending upon where you are sitting, the following two sections describe how you can set-up and use the tape drives in D405.

B.1: Using either a SONY DSR-20P DVCAM Deck (PC 11)

7. If you are sitting at PC 08 or PC 11, then begin by turning on the SONY digital tape deck and loading a pre-recorded miniDV tape into the tape drive. You will also need to ensure that the adjacent Samsung LCD TV monitor is switched on.

Press play on the tape deck and press the source button at the lower left-hand side of the LCD TV monitor to select input P98 s-video. You may need to press the source button slowly several times until the TV finds the correct input.

Ask for assistance if you cannot see your captured video displayed on the TV monitor.

Mini Project- Digital Video Editing8. If you can see your captured video displayed on the TV monitor then jump to part B.3 of this exercise.

B.2: Using a JVC HR-DVS3EK Deck (PC08)

9. If you are sitting at PC 05 or PC 14, the middle PCs of the sets of three in the middle of the lab, then begin by turning on the JVC miniDV and VHS combi digital tape deck and loading a pre-recorded miniDV tape into the tape drive. You will also need to ensure that the adjacent Samsung LCD TV monitor is switched on.

Press play on the tape deck and press the source button at the lower left-hand side of the LCD TV monitor to select input P98 S-video. You may need to press the source button slowly several times until the TV finds the correct input.

Ask for assistance if you cannot see your captured video displayed on the TV monitor.

10. If you can see your captured video displayed on the TV monitor then continue with part B.3.

B.3: Launching a new Premiere Pro Project

11. Log-in at one of the specified PCs using your LRC user name and password.

12. Launch Premiere by following the sequence; Start > Programs > Adobe> Adobe Premiere Pro CS3. The application now loads and the welcome screen appears, click on New Project icon.

13. Ensure that you select DV - PAL Standard 48kHz

14. At the bottom of the New Project box; change the default storage area for your project to the shared temporary location.

15. Enter an easily identifiable project name in the Name: field. Finally, click on OK to open the work space.

16. Click Window > Workspace > Editing to restore the default settings so that your project desktop should look similar to that illustrated below.

17. Using a dual screen PC; expand your work space across both screens placing the Project Window & History and other palettes at the top of the right screen, extend the Monitor box across the left screen, then extend the Timeline across both screens.

Note: the dual monitor setup may need minor adjustments to ensure the adjacent displays are correctly aligned. Ask for assistance if you observe a problem.

B.4: Capturing Clips from Tape

18. Click File > Capture to open the Capture window, see below. Check the Settings tab where you should see that the Capture Settings are listed as DV Capture. Click Edit… and select this option if the setting is incorrect.

Page 9 of 11

Mini Project- Digital Video Editing

19. From within the Device Control settings area, click on Options… and ensure that you have the correct physical device identified (Generic), see above right. Check also the video standard is set to PAL.

Check also that Check Status: is set to ‘Online’, if not then mouse click on Check Status which should then find the firewire device (assuming it is switched on and correctly set, see part B.1 or B.2.).

Click on OK to close the dialogue box.

20. From the Capture window; select the Logging tab and use the Premiere device controls from within the Capture window (underneath the picture monitor) rather than the controls on the actual device to spool through the tape. Watch a short sequence and identify at least three clips, each of about 10 - 15 seconds duration, for capture.

21. You can capture in several ways; movie or batch. This exercise only describes Movie Capture which means you just capture clips on-the-fly using the Record button as the tape plays; see the arrow pointing to the record button in the screen shot copied at the top of this page.

22. So, rewind again, click the play arrow and then Record to start and stop the capture. A Save Captured File dialog box opens each time to allow you to log each clip. Complete the blank fields, see above, it is very important that you provide a unique and easily identifiable name for each clip as they will be held in a common area on a network drive. Repeat this step to capture the remainder of your clips.

23. Close the Capture window when you have accumulated your set of clips. The capture window will impact on the performance of the rest of the system if it is left open, so always remember to close it when not in use.

24. Now you need to make a portable copy of the captured clips. The simplest way to do this is using a USB drive.
