The problem exists when I try to play the original 3.5 gigabyte asf file, and I have converted it to mp4 at least a dozen times, experimenting with various Handbrake settings relating to frame rate (mostly), to see if something might fix the issue and make everything settle into place. No such luck.
I did discover that up-framerating to 120 fps seemed to help a tiny bit, as did allowing for variable frame rate. But the bottom line is that I still have a 45 minute video that's really difficult to watch - particularly when played back at 4x speed, which is my ultimate goal.
So you can see for yourself, I uploaded the first minute or so of the surveillance video here. Unfortunately, playback at 4x only accentuates the stutter / jerkiness. Is the video missing a frame every ~12 frames or so, and skipping the missing frame's "time slot" altogether? (Forgive my inelegant description - this is pretty new to me.)
Is there any hope for salvaging this footage? I was thinking that creating a new video using only certain frames might work (i.e. only odd number frames, or every third frame) but I'm not sure if the frame skipping is as regular as it appears and I know that I don't know this area well. Hence the hopefully smarter move of turning to people who know what they're talking about.
I appreciate any help/guidance y'all can provide with this. Thanks!
