  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Do you save all your RAW footage for a feature film?

For the purposes of the questions that will follow on this post, let us assume the Red Epic MX 5K records Redcode 5K RAW on its storage media at roughly 300GB per hour. For a regular 90 minute feature film let us assume there is a planned 20 day shoot and each day 8 hours of footage is shot. Doing the math each day will require approximately 2.4TB of storage space to back up the day's shoot. Obviously of the 8 hours of footage shot each day, there will be takes that are not good and the Director and editor would opt to delete those takes. Obviously of all the takes for a particular shot, the Director would search for the best take and only one of the many takes would make their way into the final film.

Now let us assume the Director (for whatever reason) wanted to keep all of the footage (i.e. good takes, bad takes etc) for the entire 20 day shoot until the film was mastered and complete. This would mean storage space of 48TB would be needed to store all the footage from the 20 day shoot.

The questions here are:

1. What is the general practice adopted by most Directors/Editors in terms of workflow while on a planned time limited shoot (e.g. 10 days, 20 days etc)? After each day's shoot, do the Director and Editor generally review the day's footage and select the takes that would be used in the cut of the film and discard the remaining footage? What is the smart way of doing this?

2. To the actual RED camera feature filmmakers here, what is the size of your storage that you currently use to backup all your RAW footage shot that you use for the entire course of a feature film until the film is complete and mastered to its DCP?

3. What is your workflow? Do you discard bad takes immediately after reviewing the day's work or do you backup and keep bad takes as well?

4. Is there any pre-built storage unit/equipment that filmmakers generally use as their main backup storage during the course of making a single feature film? Is there anything out there in industry that is popular and made for this storage purpose with high speed transfer via Thunderbolt for e.g.?

Thank you.
 
To start, if we are talking narrative feature films, your assumption of 8 hours of footage is extremely high. I don't think you'd be getting much more than an hour worth of footage on a really efficient day, to just minutes on the other days, obviously depending on several factors. If you are talking documentaries, then yeah, more footage would be recorded, since interviews can go on and on, but 8 hours is still high.

And yes, you keep everything. You have a scrptie to note the circle takes, but you keep all the footage. Select the right takes in post, still don't delete anything, you never know what might become necessary down the road.
Considering the costs to produce a feature film, hard drive costs are a silly concern. Kepp everything you shoot in 3 copies...
 
I think you should keep all the footage on a RAID, and I would also get LTO tape backups as an archival copy (like LTO6 or LTO7). I would also have separate drives with copies of the final deliverables, like the conformed un-color-corrected film, plus the color-corrected film in the original resolution, and maybe even the delivered 4K, 2K, and HD versions, plus all the textless and final mixes. The book Modern Post: Digital Workflow & Techniques for Filmmakers goes into several strategies for managing all the picture and sound materials in the final stages of the process:

Thankfully we are shooting REDCODE not uncompressed ARRIRAW :wink5: ..!!
Seriously though, 8 hours equals to 32 cans of 35mm celluloid film (assuming 1 can last for 15 minutes) per day...

..and you get a free backup for at least 100 years! ;)
 
Thanks all for your great feedback.

Daniel Stilling, actually I meant on a narrative set. Also, you are right, I really went overboard with assuming 8 hours of footage on a given day.

I seem to recall that Lost (the 2004-2010 TV show) shot about 40,000 feet of film a day, because it was A&B camera and spread out over 2 separate units. Plus it was 3-perf, so every roll ran about 14 minutes and not the usual 10 or so. That worked out to about 7.5 hours a day, and it was rough. There are massive contemporary shows like Westworld and Game of Thrones that actually shoot twice as much material as this, and each series has an extended schedule of more than 10 days, which is unusual for TV. But it happens.

Almost all the Alexa crews I know are shooting ProRes 444XQ 3.2K, and we have yet to have a problem because the images aren't raw. Disk space is cheap and we can media-manage the projects down to a manageable size. I have five separate new features on my RAID right now, and I think it's under 30TB. Not that big a deal in 2018. I worry about the massive "Avengers-size" blockbusters that are taking up over a Petabyte of uncompressed EXR or DPX files. And that kind of thing has become the norm in LA.

No question, for those who have more time and money, Arriraw (3.2K, 4.5K, or 6K) is totally possible. But even then, they generally do not work with the Raw in post and instead opt for uncompressed DPX or EXR files.
