Image Sequences

The Flow

Basic image sequence usage is straightforward: Open or drag in a single image from a sequence, and u.m.p. will detect the sequence. Select a framerate, and if a multi-layer EXR, select the layer you want to load.

There are some considerations to smooth playback, though:

Decompression and i/o on large multi-layer EXRs and TIFF sequences (think 4k+), with specific compression schemes, is too heavy for the CPU-bound Open-EXR or LibTIFF extraction. The math won’t add up, no matter how many threads you throw at it (see the Cache Settings page for more info).
Because of this, u.m.p. provides the option to transcode sequences into a more memory-friendly format.

Transcoding

With pre-transcoding, you have the option to pick a resolution and compression scheme. I would recommend sticking with B44A vs. DWAA/DWAB because it decompresses faster. It has a noticeable hit on quality, but it’s fine for a quick review.
