Sony EX3 Gamma: Cine better than Std for Colored Highlights
Friday, August 19th, 2011- http://nofilmschool.com/2011/03/sony-f3-put-test-12-stops-dynamic-range/
- (Regarding the) EX1 and EX3:
- The standard-gamma knees work properly for uncolored highlights, but when a highlight has a strong chroma component, the knee shuts off prematurely, allowing colored highlights to suddenly blow out.
- The degree of this blowout depends on the saturation of the highlight, and it only happens in standard gammas…
- Cine gammas are not affected by the problem.

Avid MC: Update 5.0-5.5: AMA Plugins Not Included
Tuesday, August 9th, 2011My previous Avid MC version was able to AMA-link to XDCAM-EX files, straight away, i.e. straight after installing MC. However, having updated it to MC 5.5 (fresh install, not on top of older version) this no longer worked. Reason: the camera-specific AMA Plugins (e.g. for Sony XDCAM) are no longer bundled with MC, you have to download and install it separately.
- http://www.avid.com/US/products/Avid-Media-Access/plug-ins
- Starting with Media Composer 5.5, Symphony 5.5, and NewsCutter 9.5, you’ll need to download and install the AMA plug-ins you want separately from your editing software (these plug-ins are no longer included in the installer except for the QuickTime AMA plug-in). This enables Avid and third-party camera manufacturers to update plug-ins outside of a software release. (If you’re using an older version of Avid editing software, some of these plug-ins may already be installed on your system—please see the system requirements, below, for compatibility details.)

Avid: Ingesting XDCAM-EX
Sunday, May 8th, 2011How to ingest XDCAM-EX. The following methods exist:
- Quick:
- But this leaves it long-GOP and it remains outside AVid’s managed media database.
- Avid AMA link to XDCAM-EX’s BPAV folder.
- Avid: File > Link to AMA Volume (e.g. folder containing BPAV folder)
- Robust (or not?):
- But this leaves it long-GOP and loses some metadata ?
- http://dylanreeve.com/videotv/2009/xdcam-ex-workflow-in-avid.html
- Basically if you import clips this way you are absolutely locked in to those specific media files. No backup will allow a recovery or relink, short of storing the actual files (exactly) as they are created in the Avid MediaFiles directory.
- The easiest way to avoid this problem is actually to use the older process:
- Using Clip Browsers ‘MXF for NLE’ export setting.
- This will create OP-1A MXF files that you can then import into Media Composer
- (the Avid will rewrap them as OP-Atom and relocate them to it’s media directory).
- It is a slower process, but as it’s a standard import process all the necessary Metadata will be stored with the clips to allow a Batch Import later.
- http://dylanreeve.com/videotv/2009/xdcam-ex-workflow-in-avid.html
- Rewrap to AAF (the “newr process”
- http://dylanreeve.com/videotv/2009/xdcam-ex-workflow-in-avid.html
- Essentially this method unwraps the MP4 XDCAM-EX files and re-wraps them as MXF Op-Atom (Avid’s mediafile container) and places those files directly into one of Avid’s media directories (such as F:\Avid MediaFiles\MXF\2) and then creates an AAF file that contains a clip describing that shot (basically the easiest way to get the shots into a bin).
- ClipBrowser Help
- [Export Avid AAF] converts to the following two file formats (AAF containing pointer(s) to MXF containing media).
- AAF file: Use to load clips into Avid editing system.
- The extension is AAF, and the output destination is the media or folder specified in the Export dialog.
- AAF files produced by the conversion can be registered in your Avid editing system project by dragging from Windows Explorer to a bin in the project.
- MXF OPAtom file:
- The extension is mxf
- The output destination is the media or folder specified in the Conversion tab of the User Configuration dialog.
- Normally this is the media folder of your Avid editing system project.
- AAF file: Use to load clips into Avid editing system.
- [Export Avid AAF] converts to the following two file formats (AAF containing pointer(s) to MXF containing media).

- ClipBrowser: File > Export > Avid AAF
- But first must define the Avid project’s media location?
- [Avid MediaFiles/MXF/nn] where nn is an integer ?
- e.g. [F:\Avid MediaFiles\MXF\2].
- But first must define the Avid project’s media location?

- Luxury ?:
- Convert to DNxHD
- http://community.avid.com/forums/p/75837/552748.aspx
- If you do not have a Nitris DX system then you will have to transcode the material to DNXHD after import. I find that doing a rough cut in Native XDCAM will reduce the amount of material (and therefore time) that I have to transcode for final effects and finishing.
- Clip Browser … not needed now that AMA is working great.
- Use AMA to link to the clips/volume.
- Take a look and edit instantly onto a sequence,
- …or use the consolidate command to copy the clips at the native resolution into the AvidMediaFiles folder (aka Managed Media).
- …or use the transcode command to import the clips at an AVID DNxHD resolution of your choosing.

EX3 Shooting-Mode & Shutter Effects on Exposure
Friday, December 17th, 2010The traditional degree of motion blur, broadly consistent with what the eye normally experiences, is obtained by using around 1/50 sec shutter (no problem in practice for shutter speeds 1/48-1/60). What shutter setting (mode /value combination) can best achieve this for different shooting modes, e.g. 25p, 50i, 50p ? I am no expert on this but from my web-search I assume the following:
- For progressive modes around 25-30p, where light level allows, use Shutter On.
- But for double-rate progressive (50p-60p), use shutter-off.
- For interlaced modes or double-rate progressive or for low light situations, use Shutter Off.
- In interlaced modes, Shutter Off is equivalent to 1/50 or 1/60 (depending if 50i or 60i)
- Warning about Angles: in Interlaced modes, “180 shutter” acts more like a 135 shutter.
- The “Angles” option is really aimed at film veterans, who by definition only use progressive.
XDCAM-EX3 Picture Profiles for filmic look
Monday, August 30th, 2010XDCAM-EX in-camera compensation for Tiffen T1 “green tint”
Monday, August 30th, 2010Great article:
- http://marvelsfilm.wordpress.com/2010/04/24/all-new-sony-ex1-picture-profile-for-cinematic-look/
- “(These are) picture-settings that are tailored to my personal taste, with post-processing in mind. I’ve been able to use shots right out of the camera without the need for CC, but it does ask for contrast adjustment to taste.”
- “…the matrix corrections in the first profile are to compensate for the green hue the IR filter casts, even after taken a white balance. I use the fluorescent light matrix, simply because it does exactly two things to the picture (and in measurements) that this specific camera demands; it remove the “green Sony hue” and it is the lowest-noise matrix. It shifts the colour balance towards red/magenta, removing the green hues and preventing your cast from looking terminally ill.”
- “I use Cine 1 gamma almost exclusively because it’s clearly the most lownoise gamma. I sometimes use Cine 4 indoors with low / existing light. …adjust Gamma on a per-scene basis.”
XDCAM-EX Gamma Settings
Monday, August 30th, 2010I worried about and noticed in practice an effect where if I was using CINE gammas on the XDCAM-EX and exposed for faces at 70% (by zebras) then the gamma rolloff would result in “pasty-face” appearance. It does …and did… The solution for good looking faces is one of the following:
- Under-expose in shoot, raise in post.
- proper-expose in shoot, use standard gamma (not cine gamma), be careful not to let the face hit the knee (?) e.g. set knee to 90% or 95%.
- take a given gamma curve (or even a flat standard one) and tweak it using gamma level & black-stretch adjustments etc. until it fits the scene.
FCP inherent (unwanted) level & gamma changes - unlike Avid’s AMA
Monday, August 30th, 2010Someone noticed that XDCAM-EX footage imported to FCP appeared different as compared to Avid (AMA import). Addressed in an Avid forum thread started May 2010, referring to FCP 6.06 and Avid 4.02: http://community.avid.com/forums/p/84153/473798.aspx
- What AMA gives is, is _exactly_ what the camera has captured. What FCP shows you, is a remapped image, most often with a gamma shift.
- (For Avid AMA imports, Avid settings for RGB or 601 etc. make no difference - it’s always as-recorded).
- … imports (to FCP) will look different (to expected), because FCP/QT “corrects” the gamma when bringing in footage (even if you would not want that).
- Most people seem to agree that FCP works in 0-235, not 0-255, not 16-235. And without the option to leave things untouched. So if you import something into FCP, there’s no getting it back to the original levels anymore.
I guess I’d better do some experiments with ramps & scopes etc…
