Converting a lossless video is trimming pixels off it.
So, a client needs a render to be in a certain format.
More precisely:
XDCAM HD422 1080i60 (50mb/s CBR)
29.97, non drop upper field firstFor the workflow we are working in 29.97, and turning in uncompressed movs that are later converted to the hd422 for the turn in.
However, we’ve found that some pixels are chopped off during conversion, screwing up the format. Quicktime inspector shows me this:
1920×1080 (1888×1062)
What does this mean? What am I missing? Codecs are such a nightmare.

It means that the video window in Quicktime is that size. Not that the actual video is that size.

There’s a third value that represents that, under “current size”, i believe. Here’s what I’m seeing:9790_capture.png.zip

Yeah, the framerate is wrong on the reference file, that has since been fixed. The resolution is what keeps bugging us.

It seemed production was just using some very old software for conversion. So the problem has changed into a new one! Progress is still progress though.
So instead of making a new thread, I’ll just continue in this one for the sake of order, if that’s ok.I think I want to use adobe media encoder for the final render.
My output needs to be:
Timecode: Must be continuous and Non-Drop Frame
Extension: .mov
Codec: XDCAM HD422 1080i60 (50 Mbit/s )
Pixel Aspect Ratio: Square
Audio: STEREO ( do not unlink ) PCM 48Khz, 24 Bits (little-endian)Š Export audio
as channel grouped.
Frame Rate: 29.97 Interlaced
Resolution: 1920×1080, Upper (odd)*
Sadly, AFAIK, AE can’t export that particular audio format, so we are going to go through adobe media encoder, which is a first for me. After looking at some 101 tutorials, I think something is off. I get very few format options on the dropdown menu of the media encoder, compared to what I should be getting if the tutorials are right. I’m uploading some screenshots:
what i should be getting:
what i’m actually getting:
what could the problem be?

Do you have the XDCam plug ins installed??

I’m fairly sure, yes. I can export XDCAM footage no problem from AE.

Just quickly stopping by.
Maybe THIS > https://mediaarea.net/en/MediaInfo can be of some help along the way to check your footage.
Very helpful! Using it every day.

I don’t have an answer as to why you’re not seeing a full list of formats… perhaps you don’t have the Apple Pro Video Formats installed. But I am puzzled with the required output settings.
[Martin Pedraza] “Timecode: Must be continuous and Non-Drop Frame”
[Martin Pedraza] “Frame Rate: 29.97 Interlaced”
Seems to be a conflict there.

I’ll look for that and install it, and update, thanks!
The non-drop was my mistake, I was looking at the wrong page of the cheatsheet. The rest still stands.
