Unit 41 Application of post production techniques VIDEO AND AUDIO

Here i have changed the opacity of the clip. To fade the opening shot in from black and also to august the brightness. I decided to make the shot a bit darker than the original footage so it fitted in well with the other shots of the film. I did tho by inserting key frames and starting with the opacity low and putting another key frame with a higher opacity to increase the brightness.

Here i am adjusting the brightness of the shot, partly to disguise the face of the interviewee and to make the shot fit with the others more seamlessly to create the desired effect. i did this by putting key frames in a different points and raising the opacity for lighter effects and lowering for darker effects.

I Also decided to ajust the opacity on the title which i had on the opening shot. I did this so the title could fade into the shot after the train had past. By using key frames i was able to control the opacity. The first screenshot shows hoe i have placed a keyframe at the very beginning which has set the opacity of the title to 0.0% which means the title is not visible 

After this I moved the arrow head along roughly 3 seconds. At this point i set the opacity to 100% using the key frames. This gave me the desired effect of the title gradually fading in and i was happy with the result afterwards

AUDIO POST PRODUCTION 

Her i was editing audio out of necessity. The clip that I was using had interrupted audio because of the subject of the interview moving which moved the microphone and created un wanted feedback which was a lot loader than the audio in the rest of the clip. The content of the clip was good and i was happy with what he said but the quality was not good.  I decided to turn the volume down at the point the microphone was moved. I turned the level down to -7.3 dB which meant it was a lot quieter and the sound wasn't audible and didn't ruin the clip. 

Then i needed to bring the volume up again because it would have been to quite to keep the whole clip at -7.3dB so I set the volume up to 2.4dB  roughly 3 seconds later so the volume  of clip didnt change to suddenly. It needed to be gradual so that the clip had a better continuity and didn't sound poorley recorded. 

I Also wanted to add music to my Documentary. This meant I had to have it in the background with the audio i had recorded over the top. I realised that i couldn't come straight in with the music at its highest volume level and keep it the same because that over powered the varying levels of audio I had recorded in the interviews. I decided i needed to use key frames to just the level whilst audio was over the top 

This shows how i layered audio clips over a longer music clip. A5 is the music audio. I chose to use 'Demastas- Feel No Quilt. All the audio in the screen shot is in the final cut and is audible.

This screen shot shows how i have changed the level of the audio of the music track at different point s using key frames. It started low at -21.2dB and I changed the levels in keeping with the levels of the dialog at selected points of the documentary.
