Color showing wrong frame rate (DPXs)

Color showing wrong frame rate (DPXs)
by Rodrigo Silvestri on Sep 22, 2008 at 7:37:01 pm

Hi. This is my first post here. I am a film student, oriented mainly to the photography area, but also to post production.
I filmed a short some weeks ago, and now have the 2K DPXs here. I received them with this type of filename <7digitnumber>.dpx, and Color did show them separately, so I had to change them to .<7dign>.dpx (R3.0270001.dpx).
Now Color shows the DPX sequence instead of the files separately (that's ok), but there is a problem. Their Frame Rate is recognized as 24fps (in the file browser inside Color), and they are at 25fps (I checked them with Silverstack, and the guy from the post production house double checked them, they are at 25fps).
When I import the file, the timeline sets at 24fps, and when I render, I get a 25fps movie file with some duplicated frames.
Just in case, YES I did set the FPS to 25 before importing the file.

Any idea on how to make it work OK?

Thanks,
Rodrigo

Ok some things to try...

First off, are you importing these directly or via an EDL? If you do this via EDL, you can set the source mat'l and project framerate to 25fps. That would be the cleanest way to do it.

Otherwise.. if you're just importing raw footage directly onto the timeline.. (not sure why you'd do that)
You can overwrite each clip's framerate settings via the settings 1 tab at the bottom right corner.

If needed you can overwrite the project timeline by showing contents of the .colorproj and editing the .pdl file itself with a text editor.

Thanks Blase Theodore, but I didn't have success.

I am importing the raw DPX footage because I want to convert the DPXs to ProRes to edit them in FCP, and I can't afford GlueTools or SilverStack. Apart from that, the footage does not look good without correcting it a bit.

I had tried changing the FPS in the timeline before. This makes the project unusable. It goes crazy and all the timeline is conformed by a loop of less than 10 frames repeated over and over. Sometimes it's a continuous loop of frames and sometimes it's a mix of frames from different parts of the footage.

I tried overwriting the timeline with the .pdl file, with no success (open project and it still says 24fps in the timeline.

I just reinstalled Color, and updated it. Same thing.

Thanks!
Rodrigo

Do this.. take one of the clips, and build an EDL from it in 25fps. You can write it out by hand to a text file. (if using notepad, remember to convert to plain text first)

for example...

TITLE: 25FRAME TEST
FCM: NON-DROP FRAME

001--001------V-----C--------01:03:36:18 01:03:54:10 01:00:00:00 01:00:17:16
(replace dashes with spaces)

Read up on EDL's to understand what the numbers mean. Anyway, import the EDL, then choose 25f for all 3 settings and link to the media directory.

That will get you a 25f timeline with a single 25f clip.From there you should be able to just import the rest.

And for the record, I think you should buy gluetools. If you're already working with DPX, I don't think you understand just what kinda ride you're in for. Doing it blind will just frustrate you.

If you know someone with a Blackmagic card, try the Framelink utility. If it's a Aja card, try DPXTOQT (not sure if that's still supported)

Thanks Blase Theodore.
I used the file that Color had rendered as 24to25fps to create an EDL from FCP. Then just changed the timecodes in the file, and opened that from Color. Worked perfect.

About Gluetools: There're some things I didn't tell you at the start.
I'm a student, this is my first work in film as a DP. And I had the chance to get the scan for free. That's why I'm handling DPXs. I could have asked them to give me a graded ProRes file, but I wanted to do it for myself.
I did some tests downloading DPXs from some sites, and when I knew I could do it, I decided to have just the DPXs. But I did the tests with single frames, not with sequences. That's why I'm finding this problem now.

The total cost of the short film was AR$2000 (around US$ 700), divided into a group of 12 students. So imagine.. I won't buy a US$300 tool for something I can handle just by working a bit more.

And I don't think I'll get my next short scanned.

Thanks again,
Rodrigo

Color + DPX + 25fps = mess

You risk dropped frames, doubled frames, lost frames and all over weird behaviour.

The really bad thing is that it won|t show up before you have rendered, and it will seem ok in Color @ first.
