Film Editing: Task 3


Post Production Workflow

Assessment Task 3 – (Criteria 1.2 & 1.2)

Questions to ask yourself:

Phase 1 – Acquisition

Question 1) Why can’t we edit efficiently with ‘Lossy’ Codecs? (g)

Primarily Lossy codecs are delivery codecs which means they compress and essentially lose a lot of quality and pixels to ensure the file size transportable, they also delete most of the sample frames leaving only a few to work with, whereas in editing we need all the frames to work with, which is where a lossless codec comes out on top as they have info for every single frame. However if a lossless codec has a high bandwidth it’ll take longer to play back, and render so we still need to create a proxy file. Proxies are the intermediary  they have all the frames needed to work with yet run on a low bandwidth enabling us to play back the footage and render quicker.

Question 2) Why is it important to preserve frame rates, duration and file name when creating proxies?

Down the line it’ll cause major problems when converting the footage to an online edit as one misspelled footage file will make the rendering process halt due to an error, for example if all files were labelled Scene _ Take _ and one was labelled scene_tkae_ That piece of footage will not be accepted as the other files since it’s a labeling error. Frame rates and duration have the same guidelines in that if you shorten a clip or change frame rates as you create proxies they will cause errors down the line. Missing frame rates will force the computer to fill the space, creating something that looks just plain horrible. Already during my first edit I have encountered a problem where I have misspelled a footage clip file, it resulted in rendering issues, and this lead to RAM issues since we tried solving the problem with too many different things happening, however after rebooting the computer and going through every file of footage and correctly labeling the issue was solved.

Phase 2 – Assembly/Offline

Question 1) Why do we log and label files? (g)

Why  do we log and label files? We log and label files so that if one of the editors is sick another can just look at the logs and determine what shots will be useful for the editing process, if we did not use logs and labels we would have to go through footage several times, maybe even multiple times a day, which would mean we spent more time trying to find good quality clips instead of editing the project. Labeling and logging simply cleans up all the footage and places it into certain areas, the colour labeling in our system is green for good, amber for OK and red for bad footage, already this makes things easier, then we can look at the logs which either ourselves or another worker has completed, we can then find the clips with relative ease and know that the clip is good.

Question 2) Why does an E.D.L exist?

When the main editor is ill or incapacitated an EDL (or Edit Decision List) will be able to provide the assistant editors what the original editor wanted for his shots/cuts, ensuring that they can get on with the editing process, much like with logging and labeling files. It’s also a kind of safety net, since most film is now digital and using computers there are bound to be crashes which can corrupt editing files, having an E.D.L with you can easily allow you to redo your edit thus far. Every Professional editing software has an E.D.L you can generate and export so that if you need to switch to another computer you can just feed in the footage files and the E.D.L and the editing software will generate the same edit for you.

Phase 3 – Delivery

Question 1) Why do we ‘colour time’ after picture lock?

Question 2) Why do we sound design after picture lock?

It’s easier to synchronize dialogue and sound effects to a finished video, as apposed to an uncompleted video sequence where clips can be moved around, slowed down or changed in any way. Sound designing after picture lock saves valuable time as the sound designer will not have to alter anything with the film when it’s completed, thus creating a more efficient and fluid workflow.
