Progressive scan capturing in premiere pro?? need help

[Tim Kolb]

PPro was set to capture “no fields”?

Can you describe the project settings dialogue exactly? Are you viewing the footage on an external monitor? Routed through what?

Hi there TimK

Thanks for the reply… righto …

the project settings were set to “no frames (progressive scan)”
and all other settings were the default for 16×9 widescreen…

so Because the project was set to “no frames” i would think it would try to capture it all as prog scan … and I’ve also checked for capture settings and read some of the help files …but no luck. I can’t find specific settings for capturing prog scan or interlaced (settings are only in overall project settings)…. and yes I am viewing the video through (2) external monitor one through S-vid and other through RCA. so the computer is sending the vid to the DRS40 dvcam deck (via firewire) and then outputting it on s-vid and composite.

so I’ve got all this video which shows interlaced on a project set to prog scan… plays fine, but when i select field options in the clip window to de-interlace it, it requires that the video to be rendered…. i dunno man, i mean its ok and i can still work with it… but I just don’t know what happened …

are there specific settings for catpure (which specify fields and frame rates etc on prem pro 1.5??)

What did you shoot it with? Is it 30p or 25p…?

PPro should capture based on the project settings.

I’m not sure that DV can, by definition, be progressive and technically still be DV. BUT you can have interlaced footage that “images” as progressive. So basically, you see progressive, but the computer still sees interlace…

I’m trying to figure out just exactly just what you’re seeing.

Well… you know its a mystery to me as to why this has happened…

Video was shot on 25P (new zealand)

I shot this video on a DSR 570, which is a nice DVcam camera…and my camera man said he was absolutely sure he shot it in prog scan(can’t turn back time to check…) and so i believe him(as I’ve asked several times if it was prog scan or not) …

and another interesting thing was that when i put some of the footage into after effects for a quick grad and rendered it, it seems to be seeing prog scan (interlaced footage that “images” as progressive. as you so nicely put it)
And…. render settings were defaulted to “no fields” in AE which should be what AE has detected from the footage… and it all renders out quite nicely…

sooo… for some reason either prem has captured it in interlaced or its progscan but somehow (even after project settings were set to prog scan) it shows it as interlaced??

(am I making any sense??)

and i know its showing interlaced in premiere because when i hold on a frame i get the shudder/flicker and also on the computer i can see the interlace lines on shots with movement…

sooo… i dunno timK …have I gone crazy and seeing delusional interlace lines? (only in premiere pro thou)… strange strange strange…

I rent 570s from time to time both NTSC and PAL for film conversion and have never seen a progressive scan mode on either, there is a EVS mode which changes the vertical resolution but it still is interlaced.

Does the cam have some sort of “simulated” progressive that would output an interlaced stream of progressive frames?

I wonder if AE sees some flag put there by PPro on capture, or if because AE doesn’t work in real time, it can simply show you whatever you want, and PPro’s RT DV setting is interlaced…

George,

What happens if you watch the clip in Media Player? You know your interlaced video monitor can’t change it’s “stripes”, it has to show an interlaced version of whatever you’re feeding it. I wonder if the footage IS progressive (assuming that what you see in AE is correct) and your monitor is simply an interlaced display?

Probably what happened is the cam operator filmed in the EVS mode vice the normal interlaced, some people confuse the EVS with Pro scan because it uses individual lines in the field vice the two line overlap thats used in the normal interlaced mode, in AE in the no fields mode you probably are combining the two EVS 50i fields to form what could be looked at as a 25p frame except that there is the time difference between the two EVS fields so you can get motion artifacts and aliasing.

[Georgesfari]

Well… I guess what ever has happened the production must go on!

But yes I think you’re probably right about the EVS mode…mmmm…
the vid files seem to play fine (without interlacing) on media player…and eventually everything will go through AE to get graded and all …so hopefully it will all be ok…

I must do some more research on this EVS mode thou…

Thanks heaps for all your help timK and blast1 …

I’ll definately be posting more questions here in the future!!

Cheers heaps

oh and just one quick question before bedtime … whats the usual data rate for DV AVI captured from DVcam (16×9) ?? anyone??

[Blast1]

[Georgesfari] “whats the usual data rate for DV AVI captured from DVcam (16×9) ?? anyone??”
The data rate for SD 16:9 is the same as 4:3, 3.75MB/s, the pixel count is the same for both, 720×480 just the horiz size of the pixel is difference, .89 for 4:3 and 1.2 for 16:9
