DV video Capture

[Steve Rhoden]

You can try WinDV: https://windv.mourek.cz/
I use it quite regularly for a lot of reasons.

Thanks

I had tired several others and this one seems like its just what i need.

1) it works and is simple no extra junk
2) It uses very little cpu power avg was about 30% at full screen capture all the other programs were 80 to 100%
3) Its free
4)does not distort video when you re-size the screen it maintains aspect ratio

I noticed that it was dropping frames but so where ALL the other programs..I think its because of partial signal loss or static in the system…it only drops frames when the camera is moving (but so is the transmitter antenna) CPU never spiked to 100% that i could tell. If its not static in the system what else could cause it to drop frames?

thanks

SEE…Those are some of the reasons why i use it regularly
and highly recommends it.
As for your dropping frames, this handy little gem is the best tool
that eliminates this nag…..So i can presume that you are getting
this from sporadic signal loss during the process for some reason.

Okay that’s cool

as far as I can tell the only frames it drops are the ones filled with static…I might be wrong maybe its actually maxing out the CPU for an instant and im not seeing it on the graph.

The way it worked before I had a DV camera with AV in and i used the camera as a recording device but they had very small preview screen and often broke down..So I switched to lap top and a DV bridge between the lap top and the live feed using firewire.

I think this will work I have only ground tested it..in the air sometimes static gets very bad when the plane and receiving patch antenna are out of alignment (like when the plane is directly over head)

I’ll run the ground test on my Beefy desktop and see if it still drops frames if not I know its a cpu issue if yes then its a static problem.

Thanks again for your help

You are welcome….And let me know if it still drop frames
after you run your ground tests on your desktop.

after running the test on the desktop it was very difficult to get it to drop frames. I went outside and put lots of walls between the plane and the receiving antenna static started to increase and I did lots of high speed “banks” where the camera would move very quickly across the horizon (this would cause the lap top to drop frames) after all this torture which is far worse then actual flying maneuvers (most of the time) it only reported 232 frames dropped after 3 minutes of abuse…totally reasonable not enough to worry about.

So back to the lap top it doesn’t take long to rack up 2000 dropped frames reported (although this seems higher than it looks)again I dont see CPU going above 30 to 40% even in sustained high speed 360 circle where everything is rushing past the camera and frames start to drop.

The laptop is as far as I can tell a clean install with nothing extra on it this might be part of the problem… (bought it used)

it has: 1gb ram, Intel 1.80Ghz processor, windows xp service pack 3, geforce fx video card 32 or 64mb not sure. Make: Toshiba Tecra. I got it for making way-point and nav system adjustments in the field..I would have got a better one If I had known I was going to capture video with it. It still might be capable of doing that…

Is there a way to buffer incoming video say for 1 to 1.5 sec? The display needs to be nearly live (no later than 2 sec) for co-pilot observation of flight and recommendations.

Any software updates that might help it out?

Thanks

Here is a sample video I shot today using the laptop and winDV…Came out great…winDV reported 8000 dropped frames??? I dont see anything missing… so im happy
