| 7 | ####### Question/ My wrong understanding?
|
|---|
| 8 | This strange behaviour only makes sense, if the filter chain is interpreted as a separate container, and the output (range) key is interpreted as "additional factor, before the last factor inside -pix_fmt yuv422p10le is applied" (as opposed to yuvj...). So to say multiplied.
|
|---|
| 9 | From the documentation, I took key "range" as literal "absolute" meaning.
|
|---|
| 10 | However, the input key (irange) is -in tests- handling real input (not tested with file param "-color_range").
|
|---|
| 11 |
|
|---|
| 12 | ####### Suggestion
|
|---|
| 13 | So if this concept is ideal and intended, it may be useful to somehow make it clearer, that these range/irange are factors, not forced/absolute. Or it may be useful for the understanding, if the log explicitly prints: what levels the decoder and encoder eventually chose. That way it's easier to debug inwards.
|
|---|
| 14 | My personal experience is that I don't know enough about the code to find these answers in the source.
|
|---|
| 15 |
|
|---|
| 16 | ####### remarks
|
|---|
| 17 | - The full range file "PR4444_709_full.mov" is just in case you want to test other stuff. Not needed.
|
|---|
| 18 | - The black and white bars are meant to be visually 0% and 100% levels.
|
|---|
| 19 | - yes i think ProRes4444 is acctually by definition fullrange
