Merging pre-multiplied TIFF files

Hello,

I have a set of pre-multiplied alpha TIFF files.

I am looking for a way to encode the sequence in DXV with alpha at 60 rps.

I tried :
- adobe media encoder: it doesn't honor the "pre-multiplied alpha" metadata and "re-multiplies" the colors with the alpha channel
- resolume alley: the TIFF files appear correctly (it's honoring pre-multiplied metadata) but I could not find a way to merge the files, when I convert them, it creates .mov files for each TIFF file
- ffmpeg: I could not find a resource online so I did not go very far

If anyone could help..

Thanks

I ok I just saw this : viewtopic.php?t=18416

One just need to put them in a folder and drag them in Alley.
