Week 14 : 14 May 2014
Dr. Shafie bin Rosli was kind to give me and Mastura the chance to sit for Quiz II.
These are the questions being asked in Quiz II 2.0
1. Terangkan mengenai pemampatan video. Namakan proses pemampatan video yang anda ketahui. Apakah fungsi codec?
My answer :
Pemampatan video adalah proses mengurangkan saiz fail video agar dapat disimpan dengan lebih efisien. Video tanpa mampatan bersaiz skrin penuh selama 30 saat memerlukan ruang harddisk yang besar yang boleh menjangkaui satu Gigabait. Masalah had limit storan dapat diatasi melalui proses mampatan video digital atau codecs. Codec merupakan satu algoritma yang digunakan untuk memampat video dan nyah mampatan secara masa nyata (real-time) sebelum dimainkan semula. Codec yang berbeza dicipta untuk pelbagai metod penghantaran yang berbeza seperti penghantaran dari cakera keras, CD-ROM atau web. Codec juga mengurangkan jumlah data yang diperlukan komputer untuk memaparkan imej video di skrin monitor dengan efektif. (Norazlin Mohamed et al, 2007).
Menurut Norazlin dalam bukunya Sistem Multimedia. Terdapat dua jenis mampatan
a) Mampatan spatial: memampatkan ruang yang diperlukan untuk menyimpan setiap imej berformat JPEG. Ia berupaya menghasilkan kadar mampatan yang tinggi pada masa yang sama dapat mengekalkan rupabentuk yang serupa dengan yang asal. Mampatan spatial berlaku apabila setiap imej yang ada pada setiap bingkai dikecilkan lalu menghasilkan mampatan lossy.
b) Mampatan temporal: membandingkan persamaan yang ada pada setiap bingkai yang dimainkan dan menghapuskan data-data yang berulang. Hanya perubahan yang ketara yang ada pada bingkai-bingkai berhampiran sahaja yang akan disimpan.
2. An audio size with the following specs:
44.1 kHz
4 bytes sample size
4 minutes in length.
what will be the size of the file?
Correct answer :

After sitting for Quiz II 2.0 students were to give presentation on their proposal assignment. Below is the instruction for assignment 2
INSTRUCTION FOR Assignment 2 | VIDEO PRODUCTION PROPOSAL
In this assignment, it was designed to evaluate the knowledge and skills that students had acquired in learning about video in this subject.
Write a proposal for video production project. It is a proposal, therefore no development is needed. No specific format has been decided for this proposal as your creativity is demanded in this assignment.
The proposal must be complete and feasible. Your proposal must content:
What is your scope?
Why you choose this scope?
What is the problem that lead to your video production?
How your video can solve the stated problem in 3?
What is the pedagogical overlay will be used in your video?
Visualize your video in form of story board.
What is the software that will you use to produce your video?
What is the computer specification needed for users and for developer?
In detail, show the content of your video as explicit as possible
All of the students did an animation production but my group did something differently. We did video tutorial Microsoft Word 2010 for beginners. It was still a video production even though Dr Shafie said it was boring but we were confident we did the right thing. Video tutorial is a practical use for computer teacher to facilitate students in learning. This video tutorial can be a tool to help students in learning and help teacher in teaching. The details of assignment 2 can be seen in this link.
