6.05 - DDP export - long filename causes broken DDP

[kapverden]

Hi
not sure if this is a bug, but its strange:

if i render the DDP and give the file a name longer than 13 letters, it starts to cut of the letters of the file extension, and therefore the .DAT file is not written correctly.

f.e. "Framework Disc" will write a broken file called "FRAMEWORK DISC.DA"
while "Framework Dis" will write a correct file called "FRAMEWORK DIS.DAT"

Is there a restriction to the filename length or is this a bug?

Thanks!

Yes, there is a restriction in limit of 17 characters in DDP docs. But yes, Reaper does not check for this.

thanks for confirming -

it would be great if there was some warning when trying to render such a file though !

I don't remeber corretly right now, but when we were ironing out the DDP thing in around v6.04 and v6.05 releases I did many many test and found out that ".DAT" extension may be truncated.

But in other DDP apps was kind of similar problem. I think that I found it to cause a problem only when re-importing such DDP back into Reaper because Reaper relies on that ".DAT" extension solely, which other apps do not do.
I am sorry, but I am little in press right now and will have to remember and find the test DDP exports and maybe also re-test the behavior in all those apps to bring meaningful info to table.

So anyone, please, do not take my words as statement right now. I will be back with more correct info within a day or two, I hope.

EDIT: Quickly I think that it is 17 characters in total (in DDP specs), no matter if it is used for any filename extension (so it's minus 4 chars when .DAT is used) and so you are then limited to 13 characters for project name, but it is not necessarry because .DAT extension is not mandatory (??)... anyway, more later.

From DDP thread.
See this post.

"Just a few:

1. The filename of the DDP data file must not be longer than 17 characters (including the file extension), and 1st must only contain ASCII characters. That's a hard limit, if you choose a longer file name, it's simply not a DDP any more! Also although you or the software is free to choose a data file name, most DDP creating software uses the convention of naming it "IMAGE.DAT", I'd always stick to that, there really is no reason, Reaper should even give you a choice here."

Since DDP files are in a folder, I usually just name the folder the name of the project, and use IMAGE for the filename.
Reaper should indeed set a limit on characters there in the render dialog when rendering a DDP.

Thanks so much, Wyatt!
Reaper shouldn't even let you give it a name, but just name it IMAGE.

Yes, I think so too. This should be considered a bug IMHO.
It would be an easy fix for the developers.
Hopefully they will see this post, but at the same time, they seem pretty busy. I've included a way to do this in the DDP marker editor, but I haven't had time to work on it lately. I'll see what I can do just as soon as I get the time.
Thanks,
Wyatt

Thanks Wyatt.
I wonder how you would integrate that into your DDP Marker Editor since this is a render option?

I made a render preset for DDP, where the filename is pre set.
Thats the only solution i can see.

Thanks for your DDP Marker Editor btw, its great.

I may could send you a beta test build to check out.
Are you using Windows, or Mac?

[kapverden]

Sure, thanks!
I'm on Mac. I'll PM you my email.
