DPX is fast in AE but lack of compression and no 16-bit or float support is deal killer. TIFF LZW or EXR (half float) are superior depending on needs.

Subject: [AE] Preferred intermediate image sequence for Ae Pipeline
what is your go-to intermediate image sequence for Ae? i.e render heavy renders in Ae to save time later in the final render to container/mp4.
I moved to DPX a few years ago (after years of futile use of PNG sequence). but now I am thinking to shift to EXR half float in Ae. the size of DWAB/DWAA/ZIP is very small and I see I get the same quality (I do have to remember to use preserve
RGB in interpret footage). the render speed is almost the same. the read speed back in Ae is faster for DPX but only slightly.
