Any other workflow? https://www.personal-view.com/talks/discussion/3544/conforming-mjpegs-to-25p-with-cinema-tools-produces-files-that-fcp-wont-import.-any-other-workflow Mon, 11 Jun 2012 08:28:24 +0000 ickejohannes 3544@/talks/discussions Sorry if this has already been answered, I've been searching the forum but so far without finding a solution.

I'm trying to get MJPEGs from the GH2 to play at 25 (or 24) fps for a slight slow-motion effect. However when I conform the clips with Cinema Tools, the resulting files cannot be imported in FCP, as I get the error "File Error: Unknown File".

Does anyone know what the problem is or could help me out with an alternative workflow to get FCP to playback the MJPEGs at 24 or 25fps?

]]> Which framerate to mix 24p and HBR25/30 footage? https://www.personal-view.com/talks/discussion/2847/which-framerate-to-mix-24p-and-hbr2530-footage Thu, 12 Apr 2012 18:21:01 +0000 duartix 2847@/talks/discussions Please help!

I'm planning to do a comparison of various video modes and shutter speeds and I'd like in the end to export one video that mixes thge following material:

  • 24p footage @ 2fps that will be speed up 13x

  • 24p footage @ 2.5fps that will be speed up 10x

  • HBR30 footage @ 2.5fps that wil be speed up 12x

  • HBR25 footage @ 5fps that wil be speed up 5x

How should I handle this in After Effects?

TIA.

]]> Motion JPEG unaffected? https://www.personal-view.com/talks/discussion/2691/motion-jpeg-unaffected Sun, 25 Mar 2012 21:43:26 +0000 pdlumina 2691@/talks/discussions Other than 720p20 width/height, E/F tables, and 720pXfps.. do any other settings actually affect the quality produced by the Motion-Jpeg encoder? do the FSH/SH values have any effect? (I think not), do the Auto Quantizer/Quantizer for 720 mode affects the quality?

Does the initial quantizer, video buffer, Top/Bottom settings, 720p IPB scaling/fallback, other modes top/bottom settings? Do any of these affect the 720p 30fps Motion Jpeg encoding? because it seems to me they are only meant for AVC modes.. but I could be wrong of course.

]]> 2.35:1 Display aspect ratio in MJPEG 30fps mode https://www.personal-view.com/talks/discussion/2292/2.351-display-aspect-ratio-in-mjpeg-30fps-mode Wed, 15 Feb 2012 21:37:07 +0000 Tommyboy 2292@/talks/discussions So, I just did a quick test by setting up one of the custom dials to be fully automatic (P Mode for exposure), just in case I need to get the camera rolling quickly. I tested all the footage to be surprised by the mjpeg HD footage. This footage has 2.35:1 display aspect ratio.
