Shot progressive, FCP captures interlaced

[Rafael Amador]

Your camera shoot in Progresive, but writes interlaced.
“The progressive scanned image is divided into two segments (odd & even field) and recorded onto tape as HDV1080/25PsF(compressed in 1440×1080/50i/4:2:0).”
So don.t get shocked. However I don’t know the best workflow in those cases. I’ve never worked with HDV. But sure somebody will hel you here.

The fields are identical. FCP does the same thing with 30p from a Canon or panasonic camera. You still have a progressive look, and you can always deinterlace it later.

Have a wonderful day.

I hope the fields are NOT identical, because that would just be line doubling.

I only have experience with Panasonic, but the video is captured in progressive, but laid to tape as interlace. You still have the progressive look. Probably the same for Sony and Canon.

Yes, it’s the same theory as the panasonic. Chris meant identical as in “identical moments in time” I think.

Ok thanks for that.

But what is the workflow now? I mean do i need to change the sequence settings to reflect the 1080i50? Otherwise when I drag and drop the clip in my sequence I need to render the whole sequence again.

Thanks

Not if it is an actual progressive capture- in “P” both fields had better be the same.

[sumfun] ” but the video is captured in progressive, but laid to tape as interlace. You still have the progressive look. Probably the same for Sony and Canon”

The 1080 progressive format is called a progressive segmented frame or PsF- and everyone adheres to that format or it would not playout.

I don’t think that is quite right Gary.
The fields are not the same, but they are captured in the sensor at the same TIME. The buffer then records field 1 to the tape, then field 2 to the tape, thus recording a progressive frame onto an interlaced format. The image is progressive, but the recording is interlaced. If the fields were the same, then you’d only have half the resolution. HDCam works the same way.

My workflow in HDCam is to choose the Easy Setup of the interlaced format. Create a new sequence, then adjust the sequence settings for field dominance to “None”. Right click in the browser column “Field Dominance” for your captured clip(s) and select “None”. (BTW you can select all your clips first then right-click “None” to make it faster). Now you should be able to edit without any render bars (play the clip in the timeline natively).

Let us know what’s working for you.

Yes, what Jeff said, Thanks for the clarification.

Have a wonderful day.
