Re: [DVD-o-matic] Trim Frames Feature

Hi, it still happens to me to be a projectionnist every now and then, hence my maybe-narrow-minded point of view : imagine the face of the lonely guy in his cold 16 or more screens booth wondering why ingesting a five minutes movie lasts 2 hours... On the other side I totally also get the point about easily generating new DCP with same "whole-source-pack-of-images" But wait a minute - do I go wrong : does it mean that what ever the strim settings are, the .mxf files for video contains the whole stuff ? (and only cpl, pkl, a.s.o... are modified ?)

As Carsten suggests, I will make it an option. Carl On Fri, 12 Apr 2013, Gérald Maruccia wrote: Hi, "1.  encode only the frames within the trimmed portion." For me it should be the only way or that means you'd ingest dozens of Go into your servers only for some short playback ? Best regards, G.

Used a few other DCP creating tools before, was a bit sceptical at first about your 'all-in-one-converter'. However, great functionality in a single package, and, most important for me, all             processing/conversion steps for video and audio explained and documented.       Thanks!             Now, I'm using the most recent version 0.83/64bit Windows. Seems the Trim frames feature doesn't work. Whatever numbers I dial in for Start/End, it will always create the full length DCP from my 1:31:42             source. All dialogs show these 137564 frame count (also 'Properties'). Currently I have Start 1 and End 100, but it's creeping through the full 90mins of footage.       There's a bit of a complication here.  I think there are two ways of doing the trim:       1.  encode only the frames within the trimmed portion.       2.  encode all frames and then mark the portion to play in the associated XML metadata.       (1) would be preferable in most cases, except for the situation when:       i)  you encode a big DCP with a start trim of, say, 48 frames.       ii) you decide that after all you want a start trim of 24 frames.       Now with approach (2) this would just be a rewrite of the metadata, which is quick.  For (1) I see no way of doing it other than encoding the new frames and then copying the entire remainder of the MXF from the old to the       new.       In other words, it's a trade off between making it quick to alter start and end trims (but slower if the trims are large, as unnecessary encoding will be done) and making it quicker to do big trims (as the unnecessary       frames will not be encoded).       Maybe it should be an option, or maybe it should just go for approach (2) in all cases.  I'm not sure.  Any thoughts?       Regardless of all that, if the DCP you make with the current version does not *play back* with the trims in place, something else is going wrong!             The trim parameters do not show up in the log file. Should they?       They don't, I think; I should add them.       Best regards       Carl             - Carsten             _______________________________________________             DVDomatic mailing list             DVDomatic(a)carlh.net             http://carlh.dnsalias.org/cgi-bin/mailman/listinfo/dvdomatic       _______________________________________________       DVDomatic mailing list       DVDomatic(a)carlh.net       http://carlh.dnsalias.org/cgi-bin/mailman/listinfo/dvdomatic _______________________________________________ DVDomatic mailing list DVDomatic(a)carlh.net http://carlh.dnsalias.org/cgi-bin/mailman/listinfo/dvdomatic
