Conforming Made Simple
Conforming made simple

One of the most common questions I hear on a day-to-day basis when talking about new workflow ideas, new software, or methodologies is; will this create an issue for conforming?
Understanding what may cause an issue when conforming is very simple. Its essentially two things:
These two pieces of meta data need to match between what is in your offline editing platform and how your conform tool reads your masters. That’s it… If these match, you are good to go. Its literally that simple…
So to get a little deeper into this I will split this up into a few different sections:
If you are converting your master media into an offline codec to edit with, during this process you need to ensure you maintain a specific Tape name and TC that was decided in pre-production.
The most common thing I have seen across any job these days is: Source TC from the camera and the Filename of each shot going into the Tape field.
Within most dailies software you will have the option to embed the file name into the Tape column. This is a choice that has to be made up front by your lab or DIT and if not done correctly during the transcode, could cause issues for your conform.
If by chance you may have batch-digitized tapes at any point, you may be familiar with this process:
- Throw a tape into your deck
- Label this tape with a specific tape name
- Mark in and out points
- Log that clip
- Move on to the next shot, mark your in’s and out’s and then log the clip.
- Eventually when you have marked all of your in’s and out’s, you would hit “Batch Digitize”, or “Batch Capture”.
- The software would typically then tell you to “Insert Tape: _______”
- You then insert the tape, it looks for your in point > out point and captures that shot.
- It then looks at the next event within the batch list, looks at the Tape name and asks you to load the tape… Once the tape is loaded it captures this next shot. Etc…
The way you can easily look at file based conforming is very similar to this. Whether going tape or file based, having duplicate TCs on the same “tape” is a bad thing. The way either system will conform is:
- It looks at the tape name
- Then it looks for the TC within that tape
So to flip into file based mode… If you have essentially logged your Filename into the Tape metadata, you can now have duplicate TC’s in various shots and it will not matter. This is assuming all of your filenames are unique. Therefore your conform will:
- Look at the tape column (This is the filename)
- Look for the TC within that file
So now the conform looks to the next shot…Because its now on a new “tape”, it can have the same TC and it will conform without issue.
Within most software you use to conform you will have the ability to choose how you want to interpret the master medias Tape column. You need to match this to how ever the EDL or AAF has this meta data displayed.
Make these match…You’ve got your conform!
