MXF Grabing frames with incorrect ordering when file names begin with a digit
*Please fill in all defect information below.*
Product Version:0.29.0
GUI or CLI: GUI
Operating system: Win XP SP3
What steps will reproduce the problem?
1.Create a sequence of Frames Called "StudioHeader000"
2.Create a sequence of Frames Called "MainFilm000"
3.Create a sequence of Frames Called "Credits000"
4.Since we want them in that order but want to keep them labeled:
4.1.Prefix the StudioHeader000 with "_" ie "_StudioHeader000 to put it at the
beginning
4.2.Prefix the Credits000 with "-" ie "-Credits000 to put it at the end
6. Frames will show in the correct order when sorted by name in the folder
5. make an MXF file
What is the expected output?
an MXF file has frames in AlphaNumeric Order as seen in the folder
What is actual output?
an MXF file that goes Credits000 then MainFilm000 then StudioHeader000.
Please provide any additional information below.
From testing it seems that OpenDCP is grabbing Frames by the byte value of the
character, and not by normal FileName sorting algorithms. Since "-" has the
lowest byte value it comes first, and "_" comes last, which is the opposite of
what a folder will display.
So we can see in wrong in the folder and get the correct result, or see it
right in the Folder and get the wrong result.

This will not work. All filenames need to be the same length and share the same
base component name.

It does work, just the order is wrong. I'm talking about the conversion from a
sequence of .j2c to a single .mxf file (not the Jpeg2k compression)

Yes, by it won't work, I mean the order is not guaranteed to be correct.

Ok, I saw your documentation edit and thought that you might have
misunderstood me.

Each OS is different in how they return file listings and it can also vary
depending on which method is used to get the listing. Therefore, it is good
practice to keep filenames the same length and not mix and match prefixes or
suffixes. You should have received a warning message saying so. If not, then
that is a bug.

MXF creation happens alrigth but the output video has the wrong file number. IS

What do you mean has the wrong file number?
Original comment by [email protected] on 11 Mar 2014 at 12:34
I meant that the program was putting the Jpgs in the wrong order. It might be a
bug on OSX. I did the same process and just changed the way the files were
arranged in the finder and it got fixed. Same files, same names.. weird.
But now I have a DCP that when i try to open in DOREMI evaluation version it
says that cannot find the reference CPL from PKL.. or something like that. I
tried doing the whole thing over a couple of time and it just keep happening.
Also if a try to open in QUVIs. If I do the advance open and choose each MXF
separately it plays fine, but when I try to open the DCP it just doesn't do
anything.

Please list the first and last filename of your sequence.

13pdcp24p_000000000.j2c
13pdcp24p_000104830.j2c
Do you have any idea why the "wrapping" is not being recognized? I keep getting
the following error?

That file scheme looks fine. I wonder if starting with the digit causes a
problem.
Your other issue is a bug in DoRemi's player.

I will try and do it all over again without the digit. I will just write the
words of the name and let you know if this made a difference.
Could you tell me what is the best way to try the DCP pack. In order to deliver
it safely to a festival that might not check it themselves, thus risking a very
important projection.

I did change the digit, instead of writing 13 in numbers I put it in letters
and it worked just fine. The wrapper and title generator worked perfect.
