Thanks for the response. The particular game in mind called Counter-Strike has an in-built recorder that allows one to export .tga’s files at any set frame rate, limitless. These tgas are compiled by ‘VirtualDub’ at the set rate allowing for files that are indeed true to the set frame rate (i.e i can record at 10k fps and use 1% speed and maintain complete smoothness). The high frame rate as you would imagine is for slow-mo use like you say, the final export is 60fps.
I haven’t yet come to any conclusion to the issue, but it hasn’t lost me a ridiculous amount of time so I’ve just used a work around to address the problem shots.
Thanks for the responses guys 🙂
