yeah, this is info I was asking about - because it seems to me Cingg's
imagelist format might be not very universal even in better form with file
I think half-done toc file from image2 muxer kinda normal - this is
another corner cut by cingg. She delegates creating sequence itself to
libavformat/image2 muxer and then rely on same (ffmpeg's) demuxer to
reconstruct real paths to images on loading.
it probably fixable, but I do not have clear idea how (ffmpeg module must
communicate list of images back to cingg internals)
Sorry about this confusion and thanks for actually testing this (cingg's
output as input for other apps)
file BT about it?
I still think dpx-from-ffmpeg a bit useful even if you need to glue two
files together manually for now - due to possibility of encoding exact
range on timeline (with ffmpeg cmd line you need to know where to set your
cut points, less intuitive)
sorry about possible misunderstanding, again. May be documentation need
some additional sentence sayng that you need to use 'ffmpeg first' if one
uses ffmpeg's tiff/png image presets, so native demuxer will not choke over
incomplete toc file?
I tried to do a dpx render; it came with all the images and a TOC file

can you attach both toc files so i can experiment on them? (hopefully just
some sed + redirection will be enough - but i do not know those tools from
my memory - so i'll search online for manuals / examples)
