| How to Do Time Lapse with VirtualDub ------------------------------------------------ There are many ways to do this, but here's a simple recipe I use to create time-lapse movies: 1. Open the source AVI in VirtualDub. (Let's say an hour-long video of clouds moving real-time across the sky.) 2. Under Video => Frame Rate => Frame Rate Conversion, check Decimate and enter a value. Try 15 or 30 or 60 or 120 for example. Higher numbers = faster. Leave everything else default. 3. Set Video to Full Processing mode and select a compression codec (I use DivX 4). 4. Set Audio to No Audio. 5. Save the AVI under a new name. 6. Open this new file in VirtualDub. 7. Go to Video => Frame Rate => Source rate adjustment and check "Change to" and enter a value, for example, 29.970. Set "Frame Rate adjustment" to: Process All Frames. 8. Set Video to Direct Stream. (Do not re-encode.) 9. No Audio. 10. Save out under a new name. Done. -Russ |

| Following your steps I was able to do time lapse, thank you BUT as I have many heavy video files that I have to convert this way would there be a way to do the same in one step instead of two? I tryed to decimate by 10 and adjust the source rate to 29.97 in one step but when I save it, the results does'nt inclued the 29.97 source rate. How could I do it in one step? Tim |
