Bps?

[Sean Diamond]

I believe this has been asked before but i can't find the post or remember what it said. Basically i have a video clip (with sound) of me shooting my marker for about 5-7 seconds and i wanted to work out my BPS. I don't have any flashy software a la Cubase styli, so i don't have a clue how to find it out. If anyone could tell me how or even if they could do it for me, it would be great. Its a trivial thing really, just interested to see how fast my marker can shoot...

count really fast

or
i think you use midi player to count the spikes in the sound patterns or something along that line

P H I L I P !!!!! ( get your nerd arse over here)

use windows sound recorder

record the sound...decrease the speed by so may 100%'s to a point when you can count each shot and then divide by the original number of seconds... easy

Download goldwave and set the visual amplitude low enough that it filters out background noise....but so the waves are big enough to see.

Happy now kris?

you know those big red stationary chronographs? they can be used to messure BPS. just shoot multiple times and it will tell you. oh, and if you use a short barrel like i do with my E-Blade, and it is hard for you to get into a position where you can shoot fast, you can have someone else pick up the chronograph and turn it sideways and hold it up to your barrel.


i dont know how you could figure it out from a video though.

Airgun designs Europe's John Sosta has actually got a special peice of equipment that when you actually fire your marker on air into an actual microphone it records the time taken to do so many shots. When i was there last we got an RT to 32BPS, and im not lieing every second. As you all may know RT's have that bounce back trigger. An x-mag on the other hand was smaller but still fast at 20BPS. If you do not beleive me go visit him during the week at is Palace in colchester and ask him to give you a run of it.

By the way both RT and x-mag are fitted with LV10 valves so there is also NO!! velocity drop off.

I asked a mate (real techy guy) and he gave me some ideas, heres what i did:

Firstly i recorded the video file with sound, just a mic would be better but i only have a mic on my digital camera.

I then played this is windows media player.

Whilst playing it i pressed record in a piece of software called Nero Wave editor (comes with NeroMediaPlayer by Ahead). This recorded the sound file and made it appear on the screen as a wave going across the screen. I was then able to highlight a second in time (about an inch on the screen) and count the little waves, that represented the sound made whilst clicking the trigger. I did this for every second of the 9 second sample and then wrote the results down. All this takes 5mins.

Incase anyone was wondering the results were 10,9,11,10,10,10,9,10,2.

Excluding the 2 when i was turning the camera off i got an average of about 10bps which i'm happy with.

If anyone needs help with this in the future just pm me and i'd be happy to help...
