| + | ===== Notes about future digitization of film ===== | ||
| + | |||
| + | "We digitize dozens of formats of video, film, and audio in our studio and have a few suggestions: | ||
| + | |||
| + | 1. DPX is fine, but vary large and not very accessible. Unless you're planning on frame-by-frame restoration I might suggest something smaller like an MXF file with ProRes 444 encoding. | ||
| + | 2. For access I'd also suggest an MP4 file with high-quality H.264 encoding. | ||
| + | 3. Make sure the film is cleaned before digitization. | ||
| + | 4. You can request a 4k capture, but I think it's overkill and beyond the point of diminishing returns. A 4k capture of Standard/Regular 8 film yields about 22,000 PPI, which is way beyond what is on that film. We offer 2k+ which still captures a high-definition frame-by-frame digital file. | ||
| + | 5. The biggest practical decision might be about aspect ratio and crop. For example, are you okay with a 4:3 aspect ratio, which is the aspect ratio of the film or do you want a 16:9 file with letterboxing (black bars on sides)? And do you want to capture just the image area of the film, or are you interested in the entire width go the film including film markings and sprocket holes? | ||
| + | 6. If you get a good frame-by-frame capture you shouldn't need any stabilization. | ||
| + | 7. After the film is digitized you can review the footage and decide if it needs any colorization. You can always keep the original capture and create an alternate file that is more faithful to the original. Some films will suffer from fading that render the image very magenta or red but can be recovered digitally with color correction software." | ||
