Craig is correct. Frame Controls ON, set your field order to Upper First, and leave everything else set to Fast. It’ll take a while but it’ll give you proper 2:3 pulldown.

Then a reinstall of FCS3 is in order. Once that’s done, run Software Update and keep running it until there are no more Pro Apps updates left to install.

every time I have any issue with Compressor, this sorts it: open Compressor, go to the Compressor menu and choose Reset Background Processing. Choose Reset and Cancel Jobs. Wait a minute. Then resubmit the job. If there’s still an error, it’s not the app, it’s the source material.

This may have something to do with it:
Final Cut Pro changes an imported audio file’s playback speed if it detects that the file’s iXML TIMECODE_RATE flag is different from the Project frame rate. This results in sound playing back at a different rate than its original sampling rate, resulting in drift between picture and sound.
To make certain that Broadcast Wave files play back at the correct speed in Final Cut Pro, it is important to ensure that their time code frame rate is the same as the Final Cut Project frame rate. This also ensures that the start time code value is calculated correctly, preventing time code offsets between picture and sound.

You may have some process running in Qmaster that’s preventing this job from getting started. Usually when I get errors in Compressor, I launch Compressor and under the Compressor menu, choose Reset Background Processing / Reset and cancel jobs. Wait about a minute and then resubmit the job.

And if you want Batch Monitor to launch automatically when you compress using droplets, launch Compressor and check that box (Auto Launch Batch Monitor) in the preferences.

The only thing I can think is that somehow (maybe with the HDMI conversion) that the interlaced footage is being blended on the way in. Thereby blending two fields together into a progressive frame, which can’t be split back apart to be properly deinterlaced. That seems destructive and not the way this hardware should work, but I don’t have access to what you’re working with, so I couldn’t tell for sure. It could very well be that the HDMI conversion is not set properly. The ideal way to do this is to make sure that the HDMI converter is passing through – i.e. taking the 576i input and doing a straight A/D to 576i HDMI. I would then capture that as Apple ProRes422, 720×576, 25fps interlaced. Once captured, pass it through Compressor using the frame controls settings as above and keep it ProRes. That should knock down the file size and keep the quality high.

If you have someone willing to test on the other end, then yes, just follow as close to the spec as you are and send them your test. They’ll be able to tell you right away if what you’re doing is right or not. I think I’ve been able to play 4:2:2 MPEG-2 files in VLC but I don’t remember. Seem to recall there was something weird with audio sync – never had a sure way of QCing my MPEG-2 encodes. Good luck.

Wow – they didn’t give you a bit rate to hit or a container type (TS / PS)? This might be a little game of darts for you, trying to hit a spec without enough info. Anyway, yes 1920×1080 is 1.78:1, but many times features are shot to be matted to higher ratios such as 2.35:1. Frame size in that case is still 1920×1080, but active picture (letterboxed) is 1920×817. And 4:2:2 profile for MPEG-2 is something different. You need to be sure they want that – only certain systems can even play that back.

Question 1: why do you want to deinterlace? Are you compressing the files for web, or are you just trying to get them down smaller for archiving?
Your footage is interlaced. That’s how it came in when you captured it. Looking at it in the Quicktime Player is deceptive, as that will show you blended frames. In order to properly QC the material you’ve captured, you need to play it out a video I/O card to a broadcast monitor. There you’ll see the interlacing magically disappear, as the broadcast monitor understands that these fields are to be displayed one after the other (instead of how QT Player shows them at the same time).
Any compression you apply with Compressor will preserve the interlacing in your footage unless you deinterlace it with the Frame Controls. If you really do want to get rid of interlacing (and throw away half your vertical resolution) then set Frame Controls to Output Fields: Progressive and Deinterlace: Best.
