Skipping every other while exporting into PNG image sequence?

[_A.T.Omix_]

Hello,
I looked everywhere but couldn't find a way to export a portion of a video into an PNG (as opposed to JPEG) image sequence while skipping every other frame or every third frame.
I used to do it with VirtualDub by setting the frame rate (skip 1 frame out of 2) but VirtualDub doesn't support as many video format as AviDemux.
Is it possible to achieve this? Could anyone help me to achieve it?

The resample fps filter should do the trick

The problem with resampling is that I have to re-encode the whole video apparently. But never mind I'll delete every other frame manually.
What about saving an image sequence in a lossless format?

Use MPEG Streamclip (QuickTime installation needed):
(1) Load your video, press the I und O key on keyboard to set In and Out Markers, select Trim or Cut from the menu.
(2) Select FILE / EXPORT TO OTHER FORMATS / IMAGE SEQUENCE / OPTIONS
(3) Select PNG and make your settings (e.g. fps =12 = every other frame)

I get an "error movie is too long" when I try to export, i did trim the video to 10 seconds through.

Did a try with a 25 fps MP4 (h264/aac) movie trimmed to 12 seconds @ 12 PNG frames per second: no problem here.

If I remember correctly XMedia Recode or Format Factory should also do the job...

Tried Format Factory and it wouldn't let me export as an image sequence, Error Connexion failed.

used version of avidemux?

Perhaps a Avidemux 2.6 script to save every other frame as a bitmap file would work and then use an external app to convert to png?
