Frage von pennor:
Dezember 2005

Hello!

How can I s.einfachsten many individual frames (eg over a period of 10sec store.) Than images from a video? Does anyone know when a freeware program?

Thank you!



Antwort von Jörg:

Hi,
if the editing program (which?) it supports:
Workspace set - single sequence export. Then you have 250 pictures in the desired format.
Gruß Jörg



Antwort von Stefan:

Maybe the freeware VirtualDub. Determines if there is an AVI file is MPEG1. In the modified MPEG2 can Fcchandler of VirtualDub-MPEG2. With over DirectShow accessible Videos (MOV, WMV, ASF) can be combined with VirtualDub Avisynth. In RM, SWF, I do not know.

Good luck

Hello again!

Have now but one problem: Unfortunately, I've made with a 4:3 video to the test, the actual video is 16:9. Virtual Dub but there are always as 4:3. Can someone help me?

Thank you!



Antwort von Markus:

Hello,

a 16:9 picture has the same Resolutionwie one 4:3-Picture, ie 720 × 576 pixels. Only the pixel aspect ratio correction turns it into the desired format. On the PC, with square pixels, incidentally, both formats (4:3 and 16:9) an aspect ratio of 5:4!

" 4:3 or 5:4



Antwort von Stefan:

Do the video before saving the images correctly handle. It is synonymous in VirtualDub.

When you take the Video Filters -> Filters-> Add "Resize". The target image size you give a 1024 for the Width and Height to 576 (should be already there). As enlargement process / filter mode you take Lanczos3. Interlaced in / out should not be relevant .. Ok.
