2nd problem: compression and interlacing

[R. Hewitt]

This looks like interlace problems.

A couple of questions first:

1. Are NTSC or PAL?
2. Are you using a Matrox RTX card?
3. Did you capture your video in it’s native format and what format was it?
4. What are your project settings?

Let us know and we’ll be able to point you in the right direction.

1)NTSC
2)No
3)Took the video from miniDV tapes, thus I used .avi in PPRO 1.5
4)Project settings:
TV Standard: NTSC
Frame Rate [fps]: 29.97 drop frame
Field Order: Lower
Aspect Ratio: 4:3
Frame Width [pixels]: 720
Frame Height [pixels]: 480

Audio Summary:
Audio Format: PCM
Sample Size: 16 bit
Frequency: 48 kHz

Steve,

It really does sound like an interlace problem. Your settings appear to be correct.

Do you have a copy of Adobe Encore that you try the encoding in there?

Richard.

[R. Hewitt]

Sorry Steve,

Ignore the above, I’ve just realised you have Encore. Can you try bringing your sequence into Encore as an AVI and letting Encore do the encoding and see if this resolves the problem.

Failing that, one project I had for some reason was ingested with the wrong field order for PAL. I changed the field order on each clip within Premier Pro and all was well. Might be worth a try.

Hey Rick, thanks for your help so far.

Strangely enough, when I burnt the DVD, the image appeared fine on a set top DVD player. I tried the DVD on my PC drive but the disc either didn’t play the audio or didn’t play altogether (another problem of mine, I can’t seem to get the burned disc to play on a computer, only on set top players).

The file on my computer, however, (the .m2v file) jiggles like crazy still.

I tried saving the project as an .avi file ONCE but my computer crapped out because there wasn’t enough room on the hdd. I found this strange because the .avi file was something like 13.5 GBs when it cut out. So, no, I haven’t tried to import the .avi file into Encore out of fear that it would crash my system.

Maybe I’ll try reversing the field order for the titles only, and leave the rest of the video as is? But do I do that in PRO (while rendering) or when I’m exporting (as an .m2v file)?

Thanks for your help, again.

I would try reversing the field order in PPro prior to encoding. I’m away from my edit PC right now but I think the option is on the Clip menu?

You will need to select the clips one at a time and reverse the order. I tried selecting all clips but the option then gets greyed out.

I currently use an Apple 23″ LCD Cinema display and it always shows line tearing in moving objects when there isn’t really any in the source material. It’s a pain in the butt but I’m getting used to it.

You should be able to play your DVD’s with something like WinDVD on your PC.

Let us know if changing the field order resolves the problem.

Richard,

I ran 5 tests so far. Here’s what I did:

1)Clip > Video options > Reverse Field Dominance

Then for exporting:

Export
Video only
Work area only

Filetype
Microsoft DV AVI

Video Settings
Compressor: DV (NTSC)
Frame size: 720h 480v (0.900)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Color depth: Millions of colors
Quality: 100 (out of 100)
Fields: Lower Field First

RESULT: Crap. Flickers even more.

2)Clip > Video Options > Unchecked “Reverse field Dominance”

Export
Video only
Work area only

Filetype
Microsoft DV AVI

Video Settings
Compressor: DV (NTSC)
Frame size: 720h 480v (0.900)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Color depth: Millions of colors
Quality: 100 (out of 100)
Fields: Upper Field First

RESULT: Not as bad as the file with “Reverse Field Dominance” checked.

3)Clip > Video options > None
Export
Video only
Work area only

Filetype
Microsoft DV AVI

Video Settings
Compressor: DV (NTSC)
Frame size: 720h 480v (0.900)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Color depth: Millions of colors
Quality: 100 (out of 100)
Fields: No Fields (Progressive Scan)

RESULT: Good quality test (smooth, no interlace problems) BUT, the image jumps instead of rolling smoothly up the screen.

4)Clip > Video Options > Always Deinterlace

Export
Video only
Work area only

Filetype
Microsoft DV AVI

Video Settings
Compressor: DV (NTSC)
Frame size: 720h 480v (0.900)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Color depth: Millions of colors
Quality: 100 (out of 100)
Fields: No Fields (Progressive Scan)

RESULT: Smooth text, but text jumps up the screen (it seems to jump one line at a time, e.g. the text is one inch high, therefore, it jumps up one inch at a time).

5)Clip > Video Options > Interlace Consecutive Frames

Export
Video only
Work area only

Filetype
Microsoft DV AVI

Video Settings
Compressor: DV (NTSC)
Frame size: 720h 480v (0.900)
Frame rate: 29.97 frames/second
Pixel Aspect Ratio: D1/DV NTSC (0.9)
Color depth: Millions of colors
Quality: 100 (out of 100)
Fields: Lower Field First

RESULT: Smooth, rolling text appears but with a “shadow” text that jumps up the screen (as it did when the clip was exported with no fields).

I haven’t tried burning any of these to DVDs so I don’t know how they will play out on set top players.

As for your comment on playback on a PC, I’m using Windows Media Player and Real Media Player, the two that I thought most people would use. I haven’t tried Quicktime.

From the looks of it, the text is close to scrolling smoothly with smooth text, but there’s just something missing. What do you (or others) use to create titles for your projects?
