I have like a 10 min video that is 1 file and i want to add more than 1 effect for the video. For example for like the first 3mins of the movie i want it to be tv effect but like at 6 mins in the video i want night vision without the tv effect. How can i do that?

You can split the movie in two parts, the first part is 3 min, and the 2nd 6 min or something. Then you can apply an affect at each part.

Yup that is one way. My choice way of doing "something" to a clip is to keep those FXs relating to that EVENT as a specific manipulation. Meaning once I split the Event then I could dislodge one part of the Event from the other; have less options to adjust just exactly where I wish the FX to sustain from one to the other FX and would need to keep switching from Event PART-A to Event PART-B.

My way would be to utilise the FX Timeline Keyframer and position the K/Fs at exactly the position I want:

#1 - Apply BOTH Fxs to the Event.

#2 - Put a KF for TV Simulator at 00:00:00,00

#3 - Copy this to something just less than 6 minutes

#4 - Insert a TV-Sim KF at 00:06:00.00 and use the PRESET of "Reset To None"

.. and that has sorted out TV-sim!

Now go on and use a similar approach with the Colour Curves "Night". But this time have "Reset to None" in the period of time PRIOR to the 6mins and make it ACTIVE from 6 minutes.

If you want the Veg I have it ready for you.

Grazie

. .and more to the point, and in answering the query, this way allows us to add not only more than 1 FX, but, theoretically, ALL of Vegas' FXs!! Heavens! AND all of those to be made to fire-up and reduce and happen at at variation of speed of action - Linear, Fast, Slow Smooth . . etc etc . .

.. and then there is the very small matter of those tiny "Pre/Post Toggle" triangles too!!

Much multiple manipulation available.

Good question!!
