Problem 25i and 25p
 

Helo, I am using Premiere and Media Encoder CS6.

Problem appears when I combine 25i and 25p material from 3 cameras.

Montage is in 25i HDV sequence.

Two cameras rec in HDV 50i and photo camera (5D mark 3) recs 25p HD.

When i combine shoots, image from photo camera is flickering.

Like this: https://www.youtube.com/watch?v=7SLI...ature=youtu.be (middle shoot)

How can I combine thoose to images, 25i or 50i and 25p with no INTERLACING PROBLEM.

Any idea? I need this help, tnx :)

Anyway, look at my work: VIDEO JPL

Cao. TNX :)

Re: Problem 25i and 25p
 

The issue with middle clip is judder, brought on by panning when shooting with a slow, progressive frame rate. Hollywood movies exhibit the same issue, being shot at 24fps.

How do you plan to deliver - what format/device? If for web/YouTube, that delivery will be progressive anyway, so try editing in a 25p sequence, but I don't think things will improve. Try it though

Thanks

Re: Problem 25i and 25p
 

I think I made mistake, that interlace is because of slow motion.
So It is not problem any more. Yes it is for youtoube.

I have another problem now.

My another movie is recorded in progressive 25p HD 1980x1080.
I must burn Blu-ray disc for TELEVISON.

And I dont have any idea how to burn PROGRESSIVE material to disc with no interlacing on TV - blu ray player.

I cant burn that PROGRESSIVE Footage from Premiere CS6 25p sequence, through ENCORE to Blu-ray disc? Image on TV is not smooth, it is interlacing, flickering, have you any idea how to burn PROGRESSIVE image to Blu-ray HD.

Thanks, Primoz

Re: Problem 25i and 25p
 

25P is not a legal format for Blu-Ray.

Re: Problem 25i and 25p
 

Toss it all in to a 50i timeline and then output to a (interlaced) BluRay disc. Your progressive sourced video camera content will still appear progressive.

Thanks, what is sollution to combine those Images, I and P?

Really?

Re: Problem 25i and 25p
 

Drag the sequence for your 25p edit timeline, placing it in to a 25i timeline. Or just export out to an interlaced format per the settings in Adobe Media Encoder.

Andrew

Re: Problem 25i and 25p
 

Any of this combinations dont work, I tried much a lot.

I just cannot export progressive to DISC, It is always lagging... :(

Re: Problem 25i and 25p
 

What exactly do you mean by "lagging"?

Andrew

Re: Problem 25i and 25p
 

So on TV it is flickering, it is not smooth, it laggs a little bit, it is not like interlaced sequence that goes right.

Sorry of my english, I hope you understand me.

If I burn 25p material to Bluray or DVD it is not smooth.
It does not help if I convert that sequence to 25i, it is the same, not good result. If you say that Blurays and DVDs are not supportinh 25p material, how is it possible to use that material on Blu Ray or DVD, playing it on Televison with Blu ray Player?

Any method in Premiere CS6 for deinterlacing, interpret footage or whatever, I am exhausted of making it right :)

Re: Problem 25i and 25p
 

I think you will find that the field order (for the interlacing) is around the wrong way. Try the other one (odd/even) and see how it goes.

Andrew

Re: Problem 25i and 25p
 

Put your footage all in a 25i sequence (including the 25P material) and export to BR with a 25i preset, using UFF.

Re: Problem 25i and 25p
 

No this is not workin, as I said :(

It is just not right, seems like there is no function to convert Progressive right to Interlaced for Television.

Re: Problem 25i and 25p
 

Have you tried outputting with the interlaced field order around the other way?

Andrew

Re: Problem 25i and 25p
 

I tried almost all.

I exported from 25i to HD mpeg Blu ray 25i, upper fields, lower fields, progressive.

I exported from 25p to 25i, upper fields, lower fields, progressive.

Than I exported to h264 25i. And nothing of this gives no good result.

Always lagging, not smooth, trrrr.

No one knows really what is required to do that. Hm but I think one way must go.

Re: Problem 25i and 25p
 

Could you please upload a one minute sample and upload to YouTube? Then post the link here. It might be easier if we can see what you are talking about.

Andrew

Re: Problem 25i and 25p
 

Hey, problem on 00:53.


Any export does that. That is happenin on televison.

On Youtube this wouldnt be If I would be epxported right, but you must se what is seen on television.

Best, Primoz

Re: Problem 25i and 25p
 

Well, I've seen the lagging ... and it's not a progressive vs interlaced issue.

It looks to me as if the shutter speed on the video camera is too fast. This is why you aren't getting enough blur in the frames and hence the visual stepping / lagging / juddering. You should probably have it set to something like 1/50th sec or even as low as 1/25th sec. for your PAL frame rate of 25fps. (Especially if the dominant lighting is fluorescent.)

Can only suggest that you might add a motion blur filter to the areas of the footage where this visual juddering movement is obvious.

[Are any others reading this thread able to offer some advice or thoughts? Just in case I am wrong, that's all.]

Andrew

Re: Problem 25i and 25p
 

Not sure if you can do this in Premiere but I would create a 50p timeline and put the clips on. If the field time data is correct, the timeline will consist of pairs of identical frames created from the 25p clips and interpolated frames created from each of the two interlaced fields. Frame-by-frame examination will reveal whether the field order is correct. (e.g., check that the movement between frames is in the same direction and not two steps forward and one step back)
If it is correct, just render to 25i or 25p as required. If it is wrong, render a non-standard field order and edit the file's metadata to show the opposite field order. I've found a webpage that gives the following for Premiere Pro:

Change the field order of a clip

In the Project panel, you can change the field order of all instances of a clip in all sequences of a project.

1) In the Project panel, right-click the clip for which you want to change the field order.
2) Select Modify >Interpret Footage.
3) Choose the desired Field Order option.
4) Click OK.

Not sure whether this works in current versions of Premiere CS or CC.

Hope the above helps.

Re: Problem 25i and 25p
 

Hellou, hm, possible it is that shutter speed is too high, That is recorded with 5D mark 3 and shutter was 1/100. I will try with frame blending.

Steve, I already tried INTERPRET FOOTAGE but I am going to do it again and with different moves.

Thanks, I ll study your advices.

Andrew, maybe shutter speed doesnt matter so much, because the image on 0:41 minute is recorded with go pro which has 25p too and it is lagging too.

I think thats all because progressive image.

I ll try to interpret footage and do some tests with shutter speed.

Tnx, Best, Primoz

Re: Problem 25i and 25p
 

A shutter speed of 1/100th sec will be too fast ... so this is your problem behind the issue with the footage.

The "interpret footage" function is not what you need. You need to get some motion blur happening between the frames in order to simulate a slower shutter speed. (Not sure what the story is with the GoPro and its footage.)

Andrew

Re: Problem 25i and 25p
 

The pan in the example is way too fast.
When filming with 25p one needs to pan very sloooooooooooowly.
50p is more forgiving.

Re: Problem 25i and 25p
 

Ok tnx.

Hm, Speed of panning cant be problem in movie making production :P

Now I used function in Premiere, right click on clip - FRAME BLENDING, It is better I think, maybe I did it wrong when I recorded with shutter 1/100, I ll do some tests.

Re: Problem 25i and 25p
 

Panning speed is a big problem, its even worse in 24p.
Set shutter speed to 1/50.

Re: Problem 25i and 25p
 

Ok, I ll set shutter speed at 1/50 and ll do some tests.

Tnx

Re: Problem 25i and 25p
 

Ok, shutter speed doesnt matter so much.

Here comes idea.

If you convert 25p to 50i, that could be cool.

Premiere has a function INTERLACE CONSECUTIVE FRAMES which DO ITS JOB, but goes 200% FAST motion.

But on television is cool, not lagging like before, nice INTERLACED. But problem with speed, double speeded.

Hm, maybe I ll do it, 25p to 50i... but how .D

Re: Problem 25i and 25p
 

Guys, I solved problem.

I converted 25p to 50i with Adobe After effects - Layer - Frame Blending Pixel motion, and than I exported sequence as Upper field first.

That was only way to convert 25p to 50i.

Best regards, Primoz

Glad to know you have a solution there.
