Digital Post Framing Diagram

[J Clark]

The linked chart describes digital post production specs when dealing with a variety of formats and frame sizes from 4k down to web. Daily we negotiate digital resolutions and pixel aspect ratios on film and HD files so we I created this guide for our in-house reference when dealing with footage I/O, setting up edits and VFX composites.

There is a lot of research behind the creation of this chart, and if you find any errors, please let me know by email and we'll correct.

Thanks it looks great, will come in handy

Why does your chart mention the pixel sizes of 2K scans of the different film formats but not their 4K sizes?

[J Clark]

I have not added the various 4k resolutions because we seldom work in that format, but I plan to soon.

Thanks for posting the chart.

I'm thinking about saving 4K @ 4096*2160 for my archives, as per the DCI spec.

Along those lines, I think that physically shooting a framing chart, especially on a long-term project, can help reduce confusion downstream. Red makes a 16x9 "negative" but you may likely be framing for 1:85 or something else.
The nice thing about digital is that you probably would just shoot the chart once with each framing you'd be likely to use and keep that digital file as a "racking leader" (keeping in mind that the cameras may be somewhat unique and each camera body should have its own files) You could simply give the post house the appropriate .r3d file at the start of the project.
Shooting a movie on film usually means once per camera per show, but commercials it's every day, or even every film break, so the telecine guy has a chart at the head of each "batch" of dailies.
But I think that actually shooting a chart is a foolproof way of showing your intent with regards to framing, rather than relying on generated lines or overlays...
Cheers,
Harry

Hi J Clark,

Thanks, looks good :)

The inclusion of different reticles for compressed HD formats is confusing and irrelevant. The nature of 1440x1920 on HDCam, for instance, is that this is part of the compression scheme, and is used only to store the material on tape and restore it on playback. It has nothing whatsoever to do with the actual available picture area. Both HDCam and DVCPro are 16x9 in actual use, and what they do to compress the material for storage has no bearing on the image you're scanning.
