Hiding single frames within video footage with high frame rates

[Jim Arco]

The human eye/brain combination has an amazing ability to notice changes, so hiding a particular frame will be difficult unless it is VERY similar to surrounding frames. Search for studies done on ‘subliminal advertising’ to get more specific detail on this.

In addition, the actual playback rate of most moving imagery is limited by the physical display device. So your 240fps video will be played at 30 or 60 fps, unless you have some special device that can actually display 240 fps.

You want to hide a randomn frame?
Maybe, <———————-> the clip, so the video will be slower, and you will have all of the frames showing, then you have to delete the chosen frame,and >——-< your clip as it was before.
You have two clips to >——< , so use the same coefficient while “>——<“ing.
I think that it will be better if you : remember the initial time, then make a render of your mid-clip (just <–< your clip so the black frame is replaced) and then, open this clip in a new project and take it to the time you noted – 1 frame duration. = No coefficient.

Im sorry for the “>—–<” and stuff, but i dont know how to say that!
Hope it was what you asked for 🙂

Im newbie pls dont kill me 😡 (+ it’s my real name ! I just forgot to ulpoad the signature xD )

99 fps is the highest support but you could try 99 fps interlaced which would be 198 fps in fields. the 240fps might be slightly slower in playback. You can then conform the meta tag in quicktime back to 240fps.

As long as the interpret and compositions are the same, there won’t be any missing frames.

he could actually hide it as an interlaced frame! since 120 is half of 60, he could render out 60 interlaced lower or upper field and the frame would last 120th/sec. No way you could see that! and the extra bonus is that it would play on normal playback devices.
