Here's a short longboarding video that my friends asked me to film for them earlier this summer. As always, I'd love some feedback! I'm still working on my grading skills with Resolve Lite, and on my grain effect, which Vimeo still doesn't seem to be capable of encoding properly.

Hi Caleb, I downloaded the 77,28 MB mov file from vimeo, and it's as dark as there in the player. I guess this has to do with a very complicated bunch of correlations of color spaces, working environment, monitor gammas asf., described in the first chapters of [url="http://splicevine.com/july-color-correction/"]this[/url].

As with every challenge, having become aware of the nature of a problem is of more avail than just buying, say, an Eizo monitor, or two, three.

[color=#282828][font=helvetica, arial, sans-serif]One danger using ND faders is crushing your midtones. Midtones are what the whole grading ado is about. It can very well be that your ND has made the image too flat by dying out the precious midtones. Can be detected by watching the histogram during shooting.[/font][/color]

The second thing I noticed is, that in your upload file the block artifacts are bigger than any grain could be.

Axel, thanks so much for the detailed feedback. I really shoved this footage around pretty abusively, and on purpose. I do watch my histogram and waveform pretty closely as I grade, but one thing is I always grade in a completely dark room, and maybe I should suggest in the video descriptions that they should be viewed in a similar situation. The original footage was significantly brighter.

Concerning the Pro Res master business, I convert all my footage to 422HQ via 5DtoRGB, edit in FCP at full res, grade and replace the 422HQ source files with Resolve, then re-render in FCP and export from there to H.264. Since I am working entirely with ProRes from the get-go, is there any advantage to exporting a full ProRes before conversion to H.264?

Honestly, I'm developing an utter loathing for FCP's stupid Gamma shift business, and I'm seriously considering a workflow change so that my final export is from Resolve, not FCP.

Why 7mbps for Vimeo? Why not their suggested setting?

First, since Lion, there is no more Gamma shift within Apples native set of apps including Quicktime. Second, for FCP7, I consider Color the best program for grading. With FCP X, once you have learned the new workflow, you really need no external program for grading. Update to 10.6, and you easily work with the native AVCHD (if you like), wrapped as 'H.264-AVC' in a mov container, with no significant performance problems. As long as you export as ProRes (and with the new 'Share' windows and your own export settings, you can even export AVCHD as ProRes4444, which actually makes no sense, but indeed reduces banding to some extent), there will be no quality loss compared to an intermediate workflow.

      Hi everyone!
      I wanted to showcase my passion project "The Night Knows No Shore" here on EOSHD. I've been a long time reader of Andrew's blog and it was his footage that inspired me to get an Iscorama a long time ago. 
      After doing tests with it for a while I came up with this idea for a movie. And you can now see the result on youtube: 
      It's a project made by one single actor and one single crew member (me) with one single focal length (a Canon FD 85mm 1.8) and one single focus anamorphic lens ( Iscorama pre-36). Don't expect much action. It's a slow film with lots of monologues and no real plot. It's about one young man's thoughts on society, religion, art, philosophy, life in general. Have a look. If you don't like all the "pretentious" talking, maybe you like the footage. Let me know what you think. If you have any questions, just ask. Enjoy!
