In my subsequent project I did in fact conform using cinema tools, thanks for the info

[Ben Knight]

Thanks, Jerry. IN the end i manually added the mask file back in to the mask filter, but good to know for the future.

Thanks Michael, plenty of good info there.
In my case I had all original sound assets, so i bounced dialog and foley to a mono track, then added the orig music (unstretched) back into the FCP timeline along with the mono track.
Thanks again.

Hi Michael,
Well, guess what… I tried again with Logic. Based on your hint there, I took the original, un-sped audio file (from the 23.976) and I sped it up with Logic Pitch and Time Machine. But…I sped up by using:
25/ 23.976 = 1.042709, so i entered 4.2709 in the % speed.

Then, made sure FCP Easy Setup was 25p and 48k.

Didn’t bounce from Logic, just coped the NOW MODIFIED source aiff file (Logic destructively changes the audio file).

Brought that file into FCP, matched it with the conformed video (conformed to 25p from Cinema Tools)… and it worked! I exported the file and sync was perfect.

To me it sounds pretty damn good. Does the quality of the actors voices sound exactly the same, just a tiny bit faster? Well… maybe not EXACTLY the same, but I don’t have audio from one of the other programs to compare.

Anyway… it’s a lower budget option, and I still may go ahead and use it.

Am I missing anything in my calculations? I know you said 4.16%… but 4.2709% really seemed to work: the file matched the conformed video exactly, down to the frame…..

?

Thanks Michael. Just tried it in Logic.. brought the audio in, Pitch and Time Machine, -72cents Pitch and Harmonics…..
the bounced file drifted in Sync when brought in to FCP.
Don’t think I’ll stress out trying to get Logic to do it.
I’ll probably get it done by a tape house in LA… if i was still in Oz I’d probably call you guys. Is it within forum rules to ask which post house you and Nick work at?
Thanks for all the tips, all.

[Ben Knight]

Thanks Nick… I did indeed search the forums, though didn’t find much on the percentage of pitch correction. Some further calculations I did put the appropriate adjustment at -72 Cents, which I’ve read elsewhere is about right.

For the benefit of other readers, I’ll mention the only tool I have for pitch correction is Logic, and I’ve heard disparate reports about whether Logic 9 is appropriate for this or not.

So I think I’ll leave both video and audio conversions to the tape house. And I guess I’ll go with the speed up (pitch down) method.

It’s been good to learn more about all this though.

Cheers all

Thanks Nick,
Good to know that the Conform to 25 is considered industry standard.

And the digibeta I’m talking about is indeed intended for use Down Under. 🙂

• what software do you use for pitch shift? I’ll use Logic Studio Time & Pitch Machine at this stage I think, as mentioned, by changing pitch -70 cents or so… Actually I will also run a test of taking the original 24fps audio and reducing the duration to match the conformed movie, and see if the results differ.

• do you use Compressor for the downscaling from hd to sd?

🙂

[Ben Knight]

You know, Nick, I’m trying the conform method now.
Conformed it to 25 in Cinema Tools.

I’m experimenting with pitch shifting the audio using Time Machine in Logic Studio. It sounds pretty decent to me, have you heard anything about Logic Studio regarding it’s pitch-shifting abilities?

As far as I can calculate, I need to pitch shift down by 67 cents, here’s how I got the number.

Assuming need a decrease of 4% pitch (1 / 25th).

A semitone (100 cents) apparently = 5.946309437%

so

So 4% / 5.946309437 * 100 = about 67 cents.

Does that sound right?

And I’m just trying to do the frame resize with compressor, starting with the conformed hd file…. using “Best” for Frame resize quality.
I got to admit, it still looks a tiny bit blurry, so I will keep trying different things.

Thanks, B

[Ben Knight]

Oh, I haven’t tried that, but I certainly can. Working with 24 p pro res, would i still use 30, or 24? Can’t say I understand why your suggestion would help, but I thank you for it!

[Ben Knight]

Hi guys,

Yeah, I guess I’ll go professional Teranex.

But I’m still running compressor tests to see what I can do. Settings are as follows:

File format: DV Stream
Format PAL
Frame Controls On
Rate conversion: Fast as per Rafael’s suggestion

Questions:
Set duration to 100% or play Source at 25?

What about the settings for Resize?
Had resize to fast
Output fields: same as source
De-interlace fast

I set duration to 100% of source.

And yeah, that was still pretty blurry.

Tried again with duration: “Source plays at 25fps”
And I think that might have even been a tiny bit blurrier again.

Have I got the settings right?

Thanks a bunch.
