Has anyone used this video editor and if so how is the slow motion function in regards to pellet flight?
I use WMM and it will slow down the video to 0.125 or 1/8 speed. The thing is my camera only shoots at either 30 to 60 fps as opposed to those that film at the 240 frame rate. More frames per second more clarity I would think. This certainly is not my field of expertise. Bill

Thanks Bill. My camera only films at 30 fps and I'm wondering if WMM will still work as far as seeing the pellet in flight, or would I need a high speed camera?

FastEddie the little bit of video I have done of hunts is with my small Shot Trac camera that is set to film at 5x magnification. At 5x I don't think is not high enough to see the pellet in flight. It mounts to the side of the scope and does not film through the scope like other guys set-ups you see. They can use the scope to zoom in on subjects plus at a higher frame rate I think would make a big difference. Hopefully some with more experience will chime in. Bill

The following post contains "on the fly" math.
The slow video function of WMM is not enough without a high speed camera. All the program does is take the number of frames your camera recorded and increases the display time of each. So, when you reduce 30fps to 1/8th time you get 3.75fps, 240fps goes to 30fps at 1/8th speed. Now, factor in pellet flight time and distance to target.
Acording to my Strelok app a pellet shot at 900fps will take 0.3 sec to reach a 100yard target. That equals 1.125 frames recorded at 30fps and 9 frames at 240fps. This ratio is why you need to record at high frame rates to be able to see the flight on video.
If any of this is incorrect, someone please educate me.
EDIT: I got a few minutes free to check my math. I got the flight time numbers wrong. See post below for correction.

This post is to correct previous bad math.
A pellet at muzzle velocity of 900fps will take approximately 0.3sec to reach a 100yard target. Recording this flight time in 30 frames per second will get you 9 frames recorded, in 240 frames per second you will get 72 frames recorded. When you edit the recording for this 0.3 seconds to 1/8th speed, 9 frames recorded changes to 1.125 frames displayed per second and the 72 frames recorded changes to 9 frames displayed per second. Another factor when recording is focus. Your camera will be focused for the 100 yard shot and thus the majority of the flight time will be out of focus and possibly out of frame. The more frames you can record during flight time will give you a better chance of actually capturing a recording of a pellet.

this one was done with a regular (no high speed/slow motion)sony camcorder at 30 fps ,
then slowed down with WMM to .125x
The target was a gollf ball on top of a rock at 65 yards away .with the camcorder to the max. 60x optical zoom .
You be the judge .

That looks pretty good to me. I haven't been able to get out and shoot lately but ill give that a try. Thanks Rami

I wanted to make a video to show the differences in the recording speeds, but I didn't get a chance for it this weekend. If I get back to town before next weekend ends, I'll try to get some shooting done on film if I don't make one without shooting.

WMM applied to 240 fps (Casio EX-FH 100) three JSB Straton 16 gr .22 cal shot and filmed to 71 yard.

And three JSB KIngs shot to 51 yards:

I like the WMM program but have not tried others for comparison.
Kind regards, Harry.

Harry thanks for the video. Its nice to see your results. The pellets are certainly flying true and you shoot well too. Bill
