Last year we got introduced with Premier Pro and this year
we got a reminder of basics how to use it and some other basic information
about creating a video piece.
Some video basics that we were reminded:
Video Format Options
and terminology
Video system
PAL (Europe, most
of Asia and Oceania, most of Africa, and parts of South America) / NTSC (North America, Japan, and most
of South America)
PAL or NTSC format is the colour encoding system used by DVD
players and broadcast television.
These formats are no longer used in the same way that they
were originally intended to be. The technical challenges these encoding systems
were created to solve in the 1950’s don’t apply to the modern world. However,
DVDs are still labelled NTSC or PAL, and the timings, resolutions, and refresh
rates established in these systems are still used in modern televisions and
monitors.
Frame rate
For example: 24, 25, 29.97, 30,
50, 60 fps (frames per second)
PAL - 24, 25, 50 NTSC -
24, 30, 60
Standard output is 25 fps, so to
get the best results is better to shoot at 25 fps. The more frames per second
the more you can slow down the video, for example to capture a bullet you would
need a camera that can shoot at 10,000 fps.
Frame size / dimensions
Frame aspect ratio
4:3 (older computer monitors, iPad); 3:2 (DSLR stills, 35mm film stills); 16:10 (MacBook Pro, older iMacs); 16:9 (1080 video, 4K UHD video, HD TV, current iMacs)
Shooting setting and considerations
Shutter speed controls exposure
and motion blur, as with stills photography, but it cannot be slower than the
frame rate.
The ideal shutter speed is 2x the
frame rate, for example, for 25fps, use 1/50s.
ISO and aperture is the same as
shooting stills.
Exposure, white balance,
sharpening etc. – these should be done right when shooting, because video uses
compressed file and not RAW like in shooting stills.
When we were reminded about all of
that we needed to go out and shoot some footage for a short video about the New
Adelphi. The Premier Pro bit was just putting in files in files, cropping them,
applying transitions. In the second lesson of Premier Pro we learned how to
create stills from a video. I didn’t apply this on my final video about the
building, but I can explain (put my notes in from a lesson) how to do it.
Select the video and exact part of it that you want, then
export the series of images the same size as video is. Format: jpeg, preset:
custom. Change the size of the images to the video size. (check in info video);
frame rate: depends what detail you want (for example 6 images per sec) then
import them back into premiere as a batch. Create a folder and import images
into that bin. (bins helps to keep media panel organised)
Choose images and then create new sequence from clip.
Select all the images on the sequence and then change the speed
duration, because automatically it takes about 5 sec. for each images, which is
way too long.
And of course my video on New
Adelphi:
