GH1 - Frame Rate Conversion Tests - 720 60p & 30p to 24p vs. HPX 170 1080 24p

Thanks guys and thanks for noting and commenting on the tedious of it.
This has actually turned out to be much more rewarding than I expected though, so it's been fun finally getting it all posted.

Ok ... done some editing on the tutorials, will continue to refine.

Basically I'm recommending the all in one Compressor method over the Cinema Tools / Compressor Method and the Cinema Tools / FCP method.

Reason being in the other two methods you have to manually record and enter the duration for everything whereas, by setting the duration to "100% of Source" in Compressor in Method 1, all of the duration determining, noting, and entering is done for you - something you would have to do manually in either the Cinema Tools / Compressor version or the Cinema Tools / FCP version for each and every clip.

In Compressor
"BEST-MOTION COMPENSATED" will get you the best conversion but is 2.5 times slower than
"BETTER-MOTION COMPENSATED" which will still use the Optical Flow technology of SHAKE but render much much faster and probably be indistinguishable from "BEST"
and
"GOOD-FRAME BLENDING" obsoletes the Cinema Tools /FCP method which uses frame blending and would be the fastest method except for entering and processing each clip manually. So the all Compressor Method with the "Good" setting would be the same as doing it in FCP but you can batch everything and have it all automated.

For my workflow I'm going to try the "BETTER" setting in the all in one COMPRESSOR method.
 
thanks for doing this! i def need to get a better handle on compressor to help my work flow out. between your test here, and what iv shot so far...its clear to me 60p converts beautifully to 24p with this camera, even with a simple grab and drop to a 24p timelime. not to mention the GH1 right on par with the HPX 170 IQ
 
Thanks for writing this all down! Although I'm also from PAL land, it's still a useful resource to have. On the tests, I was amazed at how the GH1 seemed to out resolve the HPX, being able see clear down the street without the details turning to mush was pretty impressive.
 
Sorry guys, I've been swamped. Have 3 projects shooting starting 7/13.

Pappas for the frame rate test:
"standard film setting"
-2 contrast (I think)
-2 sharpening
-2 NR


For the GH1 action short it was:
Smooth Setting
-2 Contrast
-2 Sharpening
0 Color
-2 NR
I think iexposre off.

Though from Barry's preliminary tests it looks like he's finding that there's no reason to be scared of NR on this camera.

I think I would keep my Contrast at 0 now but would keep the sharpening at -2. Becuase really there's no such thing as -2 sharpening - it's not blurring the image in other words. -2,-1,0,1,2 is really 0,1,2,3,4,5. So I prefer to turn it down and add sharpening in post if I need it. There's plenty of resolution to be had and like I said -2 is not +2 blur, it's just sharpening off.

Dmoreno bear with me. It may be after the weekend before I get files up for you to play wuth.

Thank you Jack! I agree, never liked detail circuits too... Interesting what Barry feels about NR. Good for when you gotta push the ISO!

Patiently waiting for my GH1 to arrive!

All this is GREAT! But what about us, people that don't use MAC? Yes, I know all lovers of MAC mabybe thinking now... I don't have a MAC, because I hate MAC. I have my reasons.
The point is: Can I find something similar for PC? What's the equivalent of Cinema Tools?

Thanks
 
Your "Machete vs. Pipe" link leads to a statistic page, Just wanted to check out your work with this camera, Is that what your useing now on all your projects? Thanks
 
Not sure what you mean by static page - I guess you're referring to the Machete vs. Pipe thread?
The vimeo link to the actual film is about 6 lines down in large yellow letters on that page.

I don't know if I'd say I'm definitively using it for all of my projects, that's a project by project decision, but I'm very happy to own it and know I can go shoot great looking projects by myself whenever I want and I do plan to use it again.
 
LOL. I did nothing to the link - but glad you liked it. maybe you clicked on the link while they were updating the forum last night.
:beer:
 
Whatever, I 'm just happy that I was finally able to get to your short. So much I took the time to explore all your videos listed. As well as the horror-fest promo. I enjoyed all of them, and look forward to seeing your "Texas X files" treatment. Thanks Again!
 
when changing 720p60 to 1080p24 the setting is HD 10 bit uncompressed 1080p24 rite

Your general timeline settings have no bearing on the frame rate conversion. Only the frame rate setting itself, which should be 23.98, is a factor.

My settings are ProRes 23.98 for example.

But they could be uncompressed 23.98. DvcPro HD 23.98, etc.
 
Wouldn't you do the 720p60 to 720p24 (23.98) conversion, then drop the 720p24 (23.98) clip on a 1080p24 (23.98) timeline? That's what I've always done and it's worked great. I suppose you could also directly convert 720p60 to 1080p24, but I've never tried it. Does it make a difference?
