Is there a way to tell if HD files are interlaced or progressive?
Hi there,
I have received some HD files in Apple Pro Res, XDCAM 422 and some HDCAM tapes too. According to the sender, they are all in 1080 50. However, there is no mentioning in the label nor slate if the content is progressive or interlaced. Is there anyway for me to find out assuming the sender have no idea too? If so, what are the characteristics i should look out for in a file or HDCAM/HDCAM SR tape?
Thanks,

If it says 50, then it is most likely interlaced. 1080p50 is a VERY rare format, and XDCAM and HDCAM do not shoot that format.

Thanks for the reply Shane. That surely helped alot but are they ways I could tell if no information was provided at all. For example, by using the get info function in QuickTime for file based materials or perhaps an indication on the HDCAM players on the display? If so, please advise. And if that is not possible, are there any ways I can determine the above mentioned other than looking out for interlacing tell tale signs (combing effect) by jogging the video at scenes where action and movement?
In addition, are there ways to identify video with progressive segmented frames too?
Sorry to be so long winded but I need a quick way to
determine the above and I have no idea how to go about doing it. This information is required for data entry into our DAM and I can’t have our librarians coming to me each and every time the material received is missing that info. -

Nope, that only tells you what codec you are using, and the frame size. Not “I” or “P”.
[Steven Lim] ” perhaps an indication on the HDCAM players on the display?”
Yeah, that will tell you. If it says PSF, then it is progressive.

When the deck says PSF. Also, anything that is an interlaced format, but progressive, then it is PSF. 1080i 24p…that’s PSF.

HDCam will be interlaced. psf footage is progressive images in an interlaced frame. If you were told everything is 1080 50 then it will be i.

If you’re strictly talking about files, you can use a utility like MediaInfo to analyze it.

You can always import it into After Effects, use “Interpret footage” and then step field to field (or frame to frame), to see if you perceive any artifacts.
