480 vs 486 lines issue?
Found this in another thread.
“[Sean ONeil] “Like the idiotic design of what happens when you put 486 clips on a 480 timeline (it scales it instead of cropping it).”
Actually, that’s a User Pref, just turn that off and it goes back to cropping it like before. I found that FCP kept scaling my still images when I didn’t want it to. Now it leaves them alone like before.”
Could someone tell me where this setting is found?
I am bringing in footage captured through blackmagic at 8 bit uncompressed. My monitor shows jagged lines on diagonal edges in the image and I believe it is because the footage is 486. The monitor is a Sony pvm 14m2u. Any ideas if this is what is causing the problem or ???

Use the copy and paste attributes functions to reset the clips to normal.

I’m not sure what you mean. The attributes dont appear to have changed, why would I do this?
If I make the sequence 480 (vs486) everything looks gorgeous (a little soft). The problem then is everything requires rendering and that really slows me down. Could it be the monitor does not handle 486 lines?
If FCP is changing an attribute, where would I see this evident? Obviously, I really dont understand the nature of the problem.
thanks, td

It has nothing to do with the monitor.
I presume the sequence is 480 because you’re working in DV and have to incorporate full frame SD material. Is that what you’re doing? Or are you working in uncompressed? Then why don’t you use an uncompressed format sequence?
When you put the 486 clip into the sequence it conforms to DV. If you open the clip into the Viewer in the motion tab you’ll see exactly what’s been done to it. You can reset the scale and the center position if you want. Regardless the material will need to be rendered for output because it isn’t the same as the sequence sequence so it has to be rendered to the new sequence format. You might need a faster computer or hardware support to work with this material for efficiently.

Again I apologize if Im being vague.
The sequence is set to 720×486, 8 bit uncompressed. Same as the footage. Yet the image on the monitor looks jagged.
There is no rendering required as it stands. On the motion tab the scale=100, Aspect ratio=0 and the distortion corners are 360/243. So there is no scaling or distortion as far as I can see.
It appears to me to be a 480 vs 486 line issue. If I set the sequence to 480, it softens the image slightly but no more jagged edges.
My monitor is hooked up to my G5 via dvi to s-video adapter. (maybe that is the problem?)
Am I leaving anything out?

What monitor? A video monitor? Computer monitor? What size is the Canvas set to? Are you seeing interlacing on your computer monitor? Not sure what you mean by jagged and where you’re seeing them.
Why would you set the sequence to 480 if you’re working in 486? You’re scaling the image so it will become softer and the interlacing will be mushed.
All the best,

” The monitor is a Sony pvm 14m2u.”
Connected to a G5 through dvi to s-video converter. 480 looks great but not 486.
Jagged edges on diagonal lines. You know like the round edges of shoulders, round eyeglasses on the subject, etc.

Well,
480 footage in a 486 timeline is needs to be shifted one field up or down. There is a SHIFT FILTER filter in the VIDEO EFFECTS under VIDEO. Use it.
Since video is interlaced, the lower field first DV 720×480 footage is now upperfield in the 486 timeline… since you just changed the settings after the footage was there… final cut did not do this for you.
Add the shift fields to correct upper lower field issue. Now if there are 2 shift fileds filters by accident remove one.. you’re cancelling them out.

Sorry, missed the monitor connection the first time. You can’t connect it like that. You’re just putting a computer display on your video monitor. That’s not a true display of your video. You need to look at your video output as it’s supposed to be display. If you’re working in uncompressed standard def you’ll need a hardware board to be able to output the video monitor.

He’s not using 480 material. His material is 486 in a 486 sequence.

[tduncan777] “Could someone tell me where this setting is found?
“In FCP6 only, go to File > User Preferences > Editing Tab. Then on the bottom right corner there’s a check box that says “Always scale clips to sequence size”. Turn that off if you don’t want your 480 clips to scale in a 486 timeline.
