Extracting images from video clips

Images from videos

This is if you want to take a video still from a video clip and use it as a still image.

open up the video in quicktime
with the file open; hit the apple-I keys
check the format frame size ie 640 x 480
scroll on the timeline to the frame you would like to use
qt menu > file > export > select movie to picture (drop down) > options best quality
save as .jpg file (saves as .pct ‘photo-jpeg’ file)
open in photoshop and saves as .jpg
Note – some of the images may be squeezed as they are in the 16:9 video format

Squeezed images can be resolved by:
Opening the clip in QuickTime
From the drop down menus choose Window > Show Movie Properties
For a 640 x 480 image – Select Video Track, un-tick “Preserve Aspect Ratio”, change “Scaled Size” to 640×360, then hit enter.
(These frames size changes – width and height will be effected by the frame size of the original source file)
The export as above to create a .jpg

Another option is in PhotoShop using the ‘Resize Image’ function (followed by Resize Canvas to lose the letterboxing if you are working with layers)
After exporting the image using QuickTime – open in photoshop
PhotoShop > Menu > Image > Image size > (untick ‘Constrain Proportions’ > change the height i.e. to 360 > save

Q&A mashup brief, ABC TV

The ABC Q&A mash-up web page

EMT students this year (2010) are working towards producing video works for the ABC TV, Q&A mashup brief.

If you are interested in flowing an idea (political satire topic) across the image , sound and video blocks of the course this brief will give you an idea of where things are heading. Please note, based on experiences in 2009, it is a good idea to try and focus on a topic that will not date in relation to the final submission to the ABC Q&A website and program later in June.

The ABC Q&A mash-up web page. The ABC mashup call out:

Q&A wants your video satire on Australian politics. We are looking for funny, clever user-generated mashups to close the show. We want fun, fast, political videos which integrate news and current affairs with humour and wit. Q&A mashups can be on any topic. You can make your mashup an animation or feature clever editing and music. You can reference members of the panel, the news or politics in general. This is a great opportunity for anyone who wants a chance to make a political comment and get their work on national television. Mashups should be around 1 minute in length. We have selected some footage for you to get started below, but please feel free to find additional material elsewhere and to mashup between clips. So, what are you waiting for, mashup now!

About the Q&A TV program.

ALL the final works will be uploaded/submitted to the Q&A mash-up web page. Some works may be selected to be screened at the end of the program and the ABC credit the creators in the closing credits. There are terms and conditions when you submit your work which can be viewed at the bottom of the web page via the terms and conditions link. There is also conditions of use which cover copyright, which I discuss in detail below.

In week 3:
Readings and lecture discussion
Lab exercise Image 2.1 (Comic Strip) – this exercise applies to the entire IMAGE BLOCK for the next 3 weeks.
(Read details in emt_studio_2010.pdf, download from the emt blog page)
The main response to Image 2.1 in wk 3 will focus on learning Photoshop basics. Notes on preparing the comic strip.

Photoshop I would argue is the bedrock to many software that you will use. In terms of learning a generic approach to using software, Photoshop is a great place to start. At this point it is important to realise that the aim is not to teach you to be an advanced Photoshop user – this would take years as the software is used by different people for a varied specialisations. The aim instead is to provide you with an overview of the software in direct relation to the brief, the creative work you are producing. This will involve some core activities. Remembering the aim is to learn about editing.

With the copyright guest lecture next week (week 4), the best approach is to start with images on the supplied DVDs and then as you learn more about copyright begin to collect after the copyright lecture, other images from sources online.

Other notes: Research on political satire. Look for a source or sources that provide you with some insights into political satire as a genre. Political satire on wikipedia as a starting point. Review a source that you find in your journal.

Readings:
(Hand out at the lecture/labs) Scott Mc Cloud, ‘Chapter Three: Blood in the Gutter’, Understanding Comics: The Invisible Art, New York: Harper Perennial, 1994, p. 60-93
Lev Manovich, ‘Menus, Filters, Plug-ins’, The Language of New Media, Cambridge, Mass.: MIT Press, 2001, p. 129-31

comic strip preparation

Things to keep in mind before you open up Photoshop. Narrative concept: Plan your political satire theme carefully before you begin so you can focus in on the material you will search out and retrieve.

Constraints:

What are the limitations that you are working within?
a. The page size (A4) and the output normally for print is 150-300 dpi (dots per inch) upwards. This will be difficult with sourced images from the web which will be 72 dpi consistently. Therefore we will be working with this 72 dpi resolution setting for this exercise.
b. The image resolution of the images.
c. What is the output configuration – the publishing format (comic strip for print) – although we will working electronically for assessment (your submitted collage .jpg should be an A4 frame size and at a resolution of 72 dpi (as discussed)
d. You can use a minimum of six different images or more.
e. There is no speech bubbles or text in the final layout (only images). The comic narrative has to be conveyed with images only.
f. Resolution and frame size This is a comic strip, which has a print output. The set size for everybody is A4 – in this version of photoshop we can use the default file menu > new > US Paper > Letter selection to get the 21.59 x 27.94 cms size. You can make this portrait or landscape. Set the resolution to 72 dpi, don’t forget.

The editing process breaks into SELECTING, JOINING, BUILDING

SELECTING

This is a crucial process as your end work is only as good as the selections you make and organise. Even though you will always be eager to get into the edit, you need to put in as much time on selection as you will on joining and building.

Images sources and formats:

Because we are using images for the comic from numerous sources each image will have different specifications – mainly the image dimensions width and height, the resolution (pixels/inch) in photoshop. Many will have JPEG, .jpg file name which is our delivery image format for the entire comic strip. Some of them may also be other file types like .png and .gif, for example.

All this means, we need to really focus on checking what our source material is before we begin to use it. Select the image on the desktop and hit the ‘apple/command’ and ‘I’ keys to get information on the file. Check the file type; the data size; dimensions under ‘More Info’. Open the image up in PhotoShop to get more details on the dimensions and resolution menu > image > image size. This checking of the source material is really important generally, but especially when you are working with found material for something like mash-ups or a remix.

This year, because we are using images from the internet we will be breaking all the rules in regards to up-sampling and down-sampling images etc. i.e A lot of the images will be small in size and have to be scaled up which will deteriorate the quality of the image. Therefore, the aim is to get the largest image sizes you can.

If images are taken from the DVDs supplied some may be a higher dpi like 150-300 these will need to be changed to 72 dpi to work on your 72 dpi project canvas. If you need to know more about how the image dimensions change when the resolution is altered refer to this previous post on this blog.

If the images are taken as video frames from abc video clips off the DVDs provided or from the ABC websites via downloads the resolution will be 72dpi.

This is all about preparing your found images for the canvas the project photoshop file .psd that you are building your comic strip in.

ORGANISING SELECTIONS:

Editors even though they are highly creative people are incredibly well organised in terms of managing their content. This is organising and labelling content so it can be easily found and used to make the creative work.

Create a folder for the project – call it ‘comic’

Dropping your selected images into a folder named ‘originals’ in your ‘comic’ folder. Keep these as original files so you can always go back if you need to make other changes and choices later on.

Before you make changes, (Save as) each image into a separate folder called ‘authored.’ Save them as .jpg files and give them file names that you will recognise. (Save at 12 maximum resolution)

JOINING

The joining phase in this exercise is where you bring together a number of separate images to make a comic strip. This taps into the kernels and chunks exercise earlier in terms of the decisions you make in regards to the connections between those images. Often it is difficult to know what combinations will work well until you actually see things together and can learn from that combination. This means it is good to use the process of bringing things together to work out what works and what does not. This is instead of trying to plan too much on paper or in your head, “Learning by doing”, using the software to draft the work. Think of it as using the software to make sketches.

Projects

In all the software you will use it is important to understand that you have project files that you will make your work in (in this case a comic strip). These project files in photoshop are called a canvas, which where you place all your images to make the comic strip. But, in comparsion to a painting on an actual canvas you do not hand in your project file. You have to save or export the final result into a file type that becomes the final work. In photoshop we work in a .psd file and hand in a .jpg file, which is saved as that file type. In Garageband we export out of the Garageband project a .MP3 file.

Space

The arrangement of the images within the space/frame you are working with will have a significant affect on the narrative that you propose to follow. How will the concept effect the spatial arrangement of the images? – Think about scale, cropping and layout.

- In your journal – Sketch a thumbnail or A4 size layout of the images and write out any thoughts. Do some research on comics and how the design of panels are used to emphasise different stories and genres.

Check out these favourite films turned into comic strips and Scott McCloud’s website.

Tip – some people use sketched or printed versions of existing comic layouts as a guide to use in PhotoShop to help crop and arrange their six images or more.

Creating the A4 canvas (the project .psd file)

Default file menu > new > US Paper > Letter selection to get the 21.59 x 27.94 cms size. You can make this portrait or landscape. Set the resolution to 72 dpi, don’t forget.

NB – save this A4 canvas as a photoshop working file (.psd) – this means chose photoshop in the drop down (not jpeg) when you save as. You need this file to work on any changes and amendments as it keeps all your layers intact and separate.

Keep this .psd photoshop working file beside your prepared (authored) images folder in your ‘comic’ project folder.

One approach: A good starting point before you adjust images, may be to build a comic strip first with the images as they are by cropping and arranging the overall composition as a draft. This means you can work with multiple projects when you are exploring options. So, save a new project when you are going to try another approach or make considerable change. This also avoids preparing and adjusting images you may not use. Like the idea earlier of making numerous drafts to get an idea of which images you will use. The adjustment of those images in terms of tone and style, genre approach could come later.

Cropping

Referring to your narrative concept and layout plan – How will cropping help emphasise the narrative concept and connections between images? Cropping as process can have a significant effect on the meaning of an image. Again in your sketch projects play with the cropping of your selected image withing your spatial composition. Crop the same image several ways for example and then try all of them in the overall composition.

In CS photoshop use the crop tool in the toolbar. Four from top – you can also use the marquee tool 2nd from top.

If you want to keep the scale of the shot use the shift key to keep the dimensions.

Move the frame around to try out crop variations. The crop control to crop is in image >crop from the menu bar.

Save your crops in a separate folder called ‘authored’.

The layout

Each image is added to a seperate layer so you can move it independently within the comic strip. Name each layer to match the image you have added to it (hit the return key to rename). The layer window is in windows > layers on the menu bar.

Use the Transform feature to resize the images in the canvas (Apple + T) and hold the shift key down to keep the aspect ratio – constrain the original captured proportions of your image so it doesn’t get squeezed or stretched.

Tip – Best to scale down your image on the canvas rather than up as you loose quality if you scale an image up. Aim to bring them in slightly larger than the A4 canvas as discussed earlier. (This will depend on what you can source of the Internet)

Finalise the layout – save as .jpg file in the drop down. If you apple > I on this jpg example I used to get info on the file its should be 300dpi, A4 frame size. These will specifications set at 150 dpi upwards depending on what dpi you make your canvas. This will be what you need for submission of your collage 2.3 portfolio assignment. Keep the .psd working file to tweak later if required.

BUILDING

In the building phase I would see this as being about the polish you make on the JOINING phase. This includes adjustments to images, even going back using the draft composition as a template to re-build the work from scratch, as an example.

Some Photoshop tips for adjusting images:

Check these video tutorials for references on adjusting images.

Tip – Try to work in 12.5, 25, 50, 75, 100 % increments in the navigator (windows > navigator) when resizing images – this will generally give you better image representation on the screen.

Tip – If you are working at a lower percentage to fit your whole image on the screen also get into the habit of resizing your image to 100% to check your colour adjustment changes.

Tip – file > revert will take your image back to the original if you get lost with your colour adjustments.

Hue and saturation, Levels, curves video tutorial

As a rule of thumb in Photoshop CS curves and the edit fade option provide excellent basic image adjustment. You can also use the ‘levels’ function.

Image > adjustments > curves (drag the bottom left had corner to raise the blacks)

Fading – This option offers a way to fine tune the colour adjustment you have made to your image.

from Photoshop help

The Fade command changes the opacity and blending mode of any filter, painting tool, erasing tool, or colour adjustment. The Fade command blending modes are a subset of those in the painting and editing tools options (excluding the Behind and Clear modes).

Applying the Fade command is similar to applying the filter effect on a separate layer and then using the layer opacity and blending mode controls.

i.e. Edit > fade curves (the fade option chooses whatever previous adjustment you have made to the image)

In this mode there are number of choices (i.e. multiply, overlay etc.)

Adjusting colour

Tip – often it is only the black and whites that you may want to change in a naturally coloured image. Therefore > image > adjustment > desaturate then use the edit > fade desaturate with an overlay filter chosen to adjust your colour image and tweak the blacks and the whites.

You can also use the colour balance to tweak bad colour recording on the digital format.

A list of things that neither Adrian or I can monitor.
What did you not do last year that would have made a big difference to your learning?
Define a list of criteria (5 things) – These need to be specific and quantified as you have to provide evidence of the criteria you set yourself at the end of semester, in your blog.
Clarify, that you own this assessment and are the only person who can do it.
Professional accountability for your performance. These are the things I do not do as a learner, as a media practitioner.
Why document your participation in your blog? Blogging requires you to write things out within a public environment. The writing as reflection on what you are learning helps you see what gaps there are, and for example what you need to improve. This documentation provides you with some tools that will help you understand your strengths and weaknesses. You can then look at how you can make the most of those strengths.

Copyright documentary

The Revolution Will Be Animated from Marine Lormant Sebag on Vimeo.

The description of this video quoted from Vimeo – http://vimeo.com/8768785

In The Revolution Will Be Animated, documentary filmmaker Marine Lormant Sebag presents multiple viewpoints on copyright in the digital age. The film’s main character is Nina Paley, an American animator who produced a feature film called Sita Sings the Blues. Nina encountered many copyright issues with the songs she used, from 1920s´ singer Annette Hanshaw. These experiences made her realize that she didn’t want the same thing to happen to her film. She finally used a Creative Commons Share Alike license in order to free her work and present it to the world.
