Tables, graphs, and photographs can effectively convey detailed results of a PGR experiment. However, we have observed that demonstrating PGR treatment effects by time-lapse video creates a strong impact on both scientists and non-technical audiences. Time-lapse video also provides a method for obtaining a continuous visual record that can be used to establish the precise chronology of a slow process. Recent advances in notebook computers, inexpensive digital cameras (e.g. 3Com HomeConnect™), and time-lapse software (e.g. Picture WorkLive™) allow scientists and teachers to inexpensively prepare time-lapse videos. Important considerations for the production of quality time-lapse videos include: 1. treatment effects should be substantial, consistent, and visible, 2. digital camera images should be clear, 3. lighting should be constant and provide adequate brightness and proper color, 4. camera movement such as those due to vibrations should be minimal, 5. camera placement should simplify composition. Time-lapse videos of PGR treatment effects will be shown, and methods of production will be discussed.

Perkembangan teknologi maklumat semakin mendorong manusia untuk membangun dan mencipta inovasi. Teknologi dapat mengembangkan potensi manusia dalam mencipta produk moden. Transformasi teknologi yang pesat dari semasa ke semasa dengan meluasnya perkembangan media audiovisual, serta teknik dalam penggambaran video seperti selang masa dan sinematik. Kajian ini bertujuan untuk mengkaji nilai estetika teknik video selang masa dan sinematik dengan mengambil kajian kes dua video, iaitu Exploring Cultural Heritage: The Old Wall in Solo and The Beauty of the City of Solo (Surakarta). Analisis dilakukan dalam lima aspek, iaitu keunikan idea, isi atau mesej, aspek komunikatif, nilai estetika, dan kualiti teknik penggambaran dan teknik suara. Penulis memfokuskan pada analisis video teknik selang masa dan teknik video sinematik berdasarkan nilai estetik yang muncul. Nilai estetik kedua-dua video dapat dilihat dari penggunaan teknik selang masa yang mendorong perspektif penonton mengenai aktiviti semula jadi dan aktiviti sosial yang berlaku dari sesuatu objek. Setelah disatukan ke dalam projek media audio-visual, keindahan objek dapat dipaparkan. Sebaliknya, perspektif yang dihasilkan melalui teknik video sinematik memberikan rasa objek, iaitu video yang mewakili kemegahan objek warisan budaya dengan sudut tinggi terus bergerak di atas objek. Hal Ini mendorong penonton untuk memperoleh maklumat dan nilai, yang disertakan melalui teknik video selang masa dan teknik video sinematik.   The development of information technology increasingly encourages people to develop and create innovation. Technology can develop human potential in creating a modern product. The rapid technological transformation from time to time is marked by the widespread of developing audiovisual media, as well as by techniques in video shooting such as time lapse and cinematic. This study examines the aesthetic values of time lapse and cinematic video techniques by taking a case study of two videos, namely Exploring Cultural Heritage: The Old Wall in Solo and The Beauty of the City of Solo (Surakarta). Analysis was done in five aspects, namely the uniqueness of ideas, content or message, communicative aspects, aesthetic values, and the quality of shooting and sound techniques. The authors focused on video analysis of time-lapse video technique and cinematic video technique based on aesthetic value which emerge. The aesthetic value of both videos can be seen from the use of time-lapse technique that encourages perspective viewers about the natural and social activities that occur from an object. Having been assembled into an audio-visual media project, the beauty of an object can be projected. On the other hand, the perspective developed through cinematic technique video media is to provide a sense of object, a video that represents the splendor of a cultural heritage object with a high angle continuously moving over the object. This is to lead the audience to be able to obtain messages and values, which are embedded through both time-lapse video technique and cinematic video technique.

Cyanobacteria are photosynthetic micro-organisms colonizing all aquatic and terrestrial environments. The motility of such living micro-organisms should make their diffusion distinct from typical Brownian motion. This diffusion can be investigated in terms of global behavior (Fickian or not) and in terms of displacement probabilities, which provide more detail about the motility process. Using cyanobacterium Synechocystis sp. PCC 6803 as the model micro-organism, we carry out time-lapse video microscopy to track and analyze the bacteria’s trajectories, from which we compute the mean-squared displacement (MSD) and the distribution function of displacement probabilities. We find that the motility of Synechocystis sp. PCC 6803 is intermittent: high-motility “run” phases are separated by low-motility “tumble” phases corresponding to trapped states. However, this intermittent motility leads to a Fickian diffusive behavior, as shown by the evolution of the MSD with time.
