PROCEDURE TO HANDLE VFX POST PRODUCTION

Before starting vfx works final edited version of movie  should be locked .If the movie sequence isn’t  locked down before starting vfx then we may lose many vfx shots.
 
Destination timecode. & Source timecode is very important.

 The destination timecode is simply when, in time, the shot appears in the movie.Movie will be sent in reels(two reeler) i.e divided parts of the movie.The source timecode is simply where the shot appears in the original footage.In offline conversion we need to get offline rush with source timecode and clipname. The vfx artist needs reference of full scene if vfx requires continuity.

For Rig removal(wires etc.)  you need not to show in sequence. Vfx sequence should have previz if you are shooting some movie like gravity.

Generally 10bit DPX files is used in log profile for delivering VFX elements.Keep the camera’s Log colour profile don't change it to linear.Half sized quick time movies are great for online reviews.These can be supplied to the client with water mark.Final delivery of vfx should be in log.

A good naming can help prevent confusion and mental tortures during deadline.

 ·         i means input (input to VFX system)
·         YAS is the project name.
·         SNO is the vfx shot number.
·         BG the plate name.
·         v01 is the version.
·         000029 the frame number
·         dpx is the file type
.        R1 is the reel no

i is for Input. Shots sent from the conformists to VFX department have names like this:

i_YAS_R1_15_BG_v01
i_YAS_R2_20_E1_v02
i_YAS_R3_30_E2_v01
o is for output.
When the VFX team send a composite back to the editor they will name like this

o_YAS_R1_25_v03
o_YAS_R1_30_v07
e is for vfx element. This is the layer created by vfx team
e_YAS_R1_15_beautypass_v01
e_YAS_R1_10_Smoke_v02
e_YAS_R1_02_PFX_v01

So original footage coming into the vfx pipeling from editorial is an input. Shots going out of vfx to editorial reference or finalized vfx version is an output and we need to name everything else as element.

Input layers example
i_YAS_R1_14_BG_v01
i_YAS_R2_05_E1_v02
i_YAS_R1_15_E2_v01
‘BG’ is the background plate.Extra layers can simply be labled as ‘E1’, ‘E2’, ‘E3’ etc.
Sometimes layers can be named as L1,L2,L3.....etc
Footage in vfx are handled using image sequence files
I_YAS_R1_14_BG_V01.000001.DPX
I_YAS_R1_14_BG_V01.000002.DPX
I_YAS_R1_14_BG_V01.000003.DPX
I_YAS_R1_14_BG_V01…etc
Sometimes the conformists prefer not to use the i,o, or e for relinking purpose.

The VFX editor co ordinates with editor and vfx departments.

Asst editors need to create temp VFX to avoid confusion..
The visual effects list is needed to make budgets.

Vfx file info sequence can be sent with an EDL,AAF,XML or an avid bin to conformists to distribute vfx shots.

Added visual effects should be converted to log or mattes needed to colour correct properly

Dont pressurize vfx technicians which collapse their patience in work.Vfx technicians output quality depends on patience of VFX technician

Be knowledgeable about deadlines. Give people warnings about deadlines  but dont make it as torture.

 You must keep your composure.  All information runs though you, and therefore you have the power to prevent mistakes through good co-ordination. Kindly search dcstechie yash to see this blog on google search.
