Resolution mismatch

[Mathew Medeiros]

If anyone has an idea how this happened it would be great to hear from you as I'm catching hell for this...

I am using Redcine X Pro for transcoding dailies for offline edits. We shoot Epic X 5K 2:1, with 16:9 margins. In the transcode, everything is rendered as 1920x1080 ProResLT, 1/2 good debayer on all settings. All mags are copied to the bin, where a "fit height" framing preset is applied to scale the 2:1 footage to fit the 16:9 frame.

It's a proven workflow for us for years, until this morning. The footage arrived as 1920x960! That's a native 2:1 aspect, I know this. But the export window always has 1080 programmed, and I double-checked my export settings to confirm this. The editor is upset because nothing plays back in real-time, always needing rendering. I'm stumped, and more than agrivated.

I can't seem to recreate this issue. I'm getting the expected full 1920x1080 quicktimes out when I do 5k 2:1 Fit height out to a 1920x1080 1/2 Good debayer quicktime.

Can you enable verbose logging and recreate this issue, then send me a report from RCX (help->Save Report) to Redcinex at red dot com ?

I'll see what I can do when I get back to the office later tonight.

I did some tests with Redcine X Pro and can't seem to replicate the issue...

So what does it take to create a 1920x960 file? Setting a custom resolution in an export preset?
I do see that a neighboring export preset has a 1920x960 custom resolution setup, however the preset I created for the transcode was not created from that preset, nor did it have that custom resolution when I went back to check the settings (I create a new preset for every transcode I do, for such an occasion as this).

The program is telling me I did things correctly, but the transcodes say otherwise. I can't seem to replicate this issue, so what are the chances it had a glitch during that export?

The only 2 ways to get a 1920x960 output are by setting up a preset with those output dimensions, or setting the crop to 1920x960 and doing a snapshot.

It is not possible for RCX to display one preset's name in the batch list and use another for the export, it is also not possible for a user's change to a preset to effect an export listed in the batch list as this point a copy of the preset has been sealed off from all possible user interaction and sent into the export subsystem.

Just to make sure, were you exporting with build 13?

Also just to confirm that we are looking at the same thing the output resolution of the ProRes file you saw was 1920x960 in the movie inspector?
