Why 23.94/24 fps content is a very poor choice?

Recommended Posts

'WATCHOUT-codec for stable WATHOUC playback-2012.pdf' has a look at this information.

 

 

Frame-rate

 

23.98/24 fps is a very poor choice, for clips intended for 50 or 60 Hz displays

At worst, will result in severe sutttering of the video content.

 

 

 

23.94/24fps is a poor choice, because WATCHOUT did not support 2:3 pulldown?

 

Does it have other symptoms in addition to stuttering?

 

(For example, halt Display server.. lost video signal..etc)

It does, but the extra processor load for the extra work of generating those extra frames on the fly

means you will encounter the systems thresholds sooner than movies that do not require the extra work.

Will they play smoothly - yes. But where you might get four or six 29.97/30/60-p movies to play smoothly on a single computer,

you might only get two or three 23.98/24-p movies of the same size before stuttering is encountered.

i.e. use more hardware to offset the extra work needed.

Same is true for de-interlacing, although less so than the 23.98/24-p conversion.

No.

The frame blending feature introduced in recent version of WATCHOTU should make any irregularities caused by differences in framerate less noticable, since it smoothes out such differences. So I'd say go with the original framerate of your footage, and let WATCHOUT "upsample" it to its own rendering rate using frame blending, as long as you're happy with the results.
