alot has changed since i first used a camera in the preliminary task.....

As we can see the use of camera has changed and many more techniques have been exhibited, with the preliinary task i was a amatuer and very weak as i hav never used that before , the cannon 500 is a very techy piece of equipment which could only use to very basic amount when filming the prelim, i didnt know how to use many different features such as white balance.
another technique on a piece of software is final cut pro that i used in my thriller that i didnt use in thethe prelimanary task is the fade and cuts as as when  using the final cutpro earlt on istruggle the use of the software which lead to a jumpy and lack of continuity editing when watching the prelinminary task.
Another feature that was apparent in both product was the use odf sound effects and back ground music with the preliminary task we didnt know howto contro the sound effects andplace them more accurately to what i was trying to portray,whereas i was more specific in placing the the crow sound effect in my last product , as sound was a crutial feature that was highted the final product.

Chroma Kay/ Dolly work

Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing two images or video streams together based on color hues

when using the chroma key on final cut pro its hard to get clear back ground due to my lack of experience, the back ground has a slightly fizzy texture on the background , Also there is a a visible difference in the lighting  in the corner.
with help from youtube i have learnt how to remove the technical difficulties for next time i am editing for my actual music videos.

(disclaimer not the song i lip sink to )This is the actual final first try at using the chroma key on final cut pro 

 I tried an experiment of using the Dolly with the Chroma Key this is to try and create different aspects and effect by combining two different techniques also , at the end of this experiment if found that it could be done but i will possibly have to attach the green screen on the dolly , this is also something i will have to experiment with to get maximum potential out of it .
