Increasing speed issue
-
Today is proving to be strange Isadora day. I have a scene where an envelope generator increases the speed of a movie from 1.3 to 1.5. When it does this the video really chugs, but the FPS says 30. If I run the movie at 1.5 speed, without ramping it up through the envelope generator, it runs perfect.
Any thoughts?Jamie -
Maybe too many vales, stepping this value every few frames will not give stepping artefacts visually but will give less vales and handling to the system.

I think Fred is right.
How long does it take to get from 1.3 to 1.5 also?Codec specification is also a critical choice here too. -
Skulpture. It's taking 10 seconds. We have 1024 x 768 files with Photo jpeg compression. Thank you for your help...again. Jamie

Is there anything I'm doing wrong with compression for this particular issue?

The video codec may have a big impact. H264 for example won't like speed changes. Prores or hap are probably best. Also, adding a MultiBlocker before the speed input might help. Start with a time of 1/30 And try 1/15 These should allow a value per frame or per 2 frames.. not sure what will perform best, but these are my starting points for testing.
