Sourcing Free High-Quality Stock Imagery

Finding good stock photos is a little bit like Black Friday shopping, there are too many options and most of them are bad. Itâ€™s an art to find the gems that are of great quality at a reasonable price. Dustin Semos was kind enough to compile Stock photos that donâ€™t suck â€” aÂ list of places to find the best free stock photos.

Below Iâ€™m building on his list and present each site with some descriptions and examples.

Little Visuals

Little Visuals publishes 7 high-res images every week and offers an email subscription so you donâ€™t miss out on any new photos.

Sourcing Clips for VJing

Paid resources

If you do commercial work and/or are looking for a specific clips that you canâ€™t find on the free market, the following resources might be of help.

VideoHive

Envatoâ€™s marketplace is a great location for affordable videoclips, after effects templates and stock footage.

TripleWideMedia

A great resource for double-wide or triple-wide projection setups. Focussed on churches, but also non-church performers can find some good footage. At the time of writing clips cost $12USD and for that price come in HD, double-wide and triple-wide resolutions.

Pond5

Pond5 offers stock-video usually under $100USD.

VideoBlocks

VideoBlocks offers access to their entire library for a monthly fee ($79USD a the time of writing).

iStock

iStock offers high quality footage at high quality prices.Â

Free resources

Creative Commons Licensing

Creative Commons (CC) licensesÂ have become a popular copyright licenses that gives the author protection of their work while still allowing others to use it within certain limits. This is good news for artists trying to sample, remix or incorporate media into their own work.

Creative Commons currently offer six licenses:

Four out of the 6 allow remixing and with that are perfect for VJs. Two donâ€™t, so make sure you steer clear of clips using those.

Â

Remix-friendly licenses

Â Attribution (CC BY)

This license allows you to distribute, remix, tweak, and build upon the original, even commercially, as long as you credit the author for the original creation.

Â Attribution-ShareAlike (CC BY-SA)

This license is identical with the one above, but requires you to share your work under the same license.

Â Attribution-NonCommercial (CC BY-NC)

This is the attribution license limited to non-commercial work.

Â Attribution-NonCommercial-ShareAlike (CC BY-NC-SA)

This requires attribution, only non-commercial use and requires you to share your work under the same license.

For non-commercial VJ sets all of these are an option and will open up a larger pool of media when searching the sources below.

For commercial use the first two still provide great options.Â

I usually start searching for (CC BY) and then expand from there.Â

Â

Non-Remix-Friendly licenses

There are two licenses that do not permit remixing (No derivative works). In most cases these wonâ€™t work for a VJ setup and I recommend steering clear of them.

Â Attrribution-NoDerivs (CC BY-ND)

Â Attribution-NonCommercial-NoDerivs (CC BY-NC-ND)

Â

Free Video Sources

Vimeo

Vimeo letâ€™s you filter by any or all Creative Commons licenses as well as for downloadability.

YouTube

YouTube gives you fewer controls, but does offer an extraordinarily large collection of videos. To download a tool like KeepVid will be needed.

Wikimedia Commons:Videos

Wikimedia has a good collection of videos from the Wikipedia universe that is full of interesting short clips and video footage. Â

Archive.org

Archive.org is a large library of media in the public domain or otherwise free to use. It is great for vintage finds. Dario Salvi recommendsÂ the Prelinger collection and the Ephemeral library.

Beeple

Beeple akaÂ Mike Winkelmann is a generous 3d video artist and a VJs best friend. His always growing collection of mesmerizing 3d video loops will have something for you.Â

Learning Regex

Regex, Regexp or Regular expressions are a special syntax used in programming to search for patterns in a text. They are often used to validate form input, or for intelligent search and replace. The Regex markup looks very complicated as it is often a long string of characters.

(\d{5}([\-]\d{4})?)
This Regex pattern validates the US-postal code format

Regex itself follows a very logical pattern and can be very powerful and much easier than other attempts at parsing text. Whether you need simple format conversion (US to European numbers, “–” to “â€””), email address validation in web forms,Â or validate if the password your users create matches your required format, Regex can be of help.
