Tip to making Dailes from EPIC - FIT HEIGHT

[dino g]

as deanan has pointed out, 5kFF is slightly different than 16:9. ...

Epic S35's 5K FF is 5120x2700 and is a 1.896:1 aspect ratio.

1.896: is also the ratio for the 4k/2k DCI formats:
4096x2160 = 1.896:1
2048x1080 = 1.896:1

thus when using the default framing settings of "fit width" in redcine-x" you will inadvertently create dailies that can be perceived as being stretched vertically, ever so slightly, and are slightly letter boxed.

ALSO it is important to EXPLAIN to the DP that the 16x9 guides are what the dailies will look like, i.e. slightly cropped/center cut from what is being seen on set. but that the extra pixels are available for pan and scan in the final cut if needed...

so it is VERY IMPORTANT to CHANGE the framing settings to "FIT HEIGHT".

to do this,

1. open the export tab

2. scroll down to the "framing control" area in the export settings ( it is at the bottom)

3. select "Fit Height" from the "fit" pull down, ( it is the first thing you see in the framing control panel)

4. under the framing presets, hit the "+" box to create a new preset.

5. name it what ever will make you remember it, you will use this preset on every job for the most part if you are doing commercials.

6. hit enter

7. make sure "BIN (selected clips) is the the selected option in the EXPORT drop down.

8. take all the clips you want to transcode and highlight them (apple A is best for this on a mac)

9. move the clips to the bin

10. do another apple A to select them all in the bin.

11. go back to the export screen and double click on the framing preset you made..

continue with the process of making your dailes as you normally would, i.e select your codec, do your color grade...and push out your dailies...

happy encoding!

here is how the default framing control panel looks...

this is what a 5kFF framing control panel should look like..

Thanks for the tip Dino!

as deanan has pointed out, 5kFF is slightly larger than 16:9. thus when using the default framing settings of "fit width" in redcine-x" you will inadvertently stretch the footage vertically, ever so slightly.

No, you won't. You will have a bit of black at the top and bottom, a slight letterbox. The only way the picture would get stretched is if you used stretch W & H. That will do a "fit both" operation that will alter the aspect ratio.

you are wrong. i can't explain it, perhaps someone from red can, but the footage is stretched vertically ever so slightly, hard to see with an untrained eye.

i have processed about 20 tb of EPIC footage... this is a fact!

Hmmm. That would definitely be a bug if true. I'll try a few tests when I get back to work tomorrow. What version of RedcineX are you using?

I'd point out that one aspect ratio isn't "bigger" than another, it's a ratio. IMAX is around 4x3 after all. Something can be shorter or wider, etc. than 16x9, but "bigger" doesn't make much sense.

 

[dino g]

changed to different from "larger" i dont think i wrote "bigger"...but i am sleep deprived because of this...not the post, but having to re-do yesterdays dailies.

however, i am trying to help people avoid making the same mistakes i have made by pointing out something that is different than the way we have been doing things for the last few years...not a big deal, just a little different. i for one, certainly appreciate another perspective about the same subject and moreover, the nuances with language and grammar that are necessary to convey the appropriate message so that is can stand up to industry scrutiny.

so thank you david and mike for making this post as correct as possible.

(disclaimer...i am a math guy, not an english guy, please note that when dissecting my posts.)

The difference is that to get 16:9 out of a 1.89, you either need to set an explicit crop of 4800x2700 or do fit height which would do the same.
If you don't you get letterboxed image with fit width.
The same would be true if you shot 2:1 or wider formats.

Glad to know I haven't totally lost my mind. :thumbup1:

Thanks a million for pointing this out Dino!

Still a few shards left :w00t: hehe

BTW - couldn't hurt to shot the framing chart from the DSC Red Cambook at the start of each project, it also provides a convenient color temperature reference at the same time - popular with colorists, no matter how many (or few) brain cells they may have current access to :cheers2:
