  • Red/blue frames in sony vegas using Twixtor

    Hello! Not sure if my support mail got sent out, so im briefly explaining my issues here.
    When using twixtor i ran into a problem where the video i was using it on had some frames turn purely to blue or red. I checked every tutorial and forum and seen as i did not set the twixtor speed to engative or 0,i dont know what the issue there is.
    I also saw somebody say you needed to use twixtor as a media effect rather than a video effect when making the clip shorter (which is what i was doing, i was speeding it up)
    But when i tried to set up the keyframes for twixtor using it as a media effect, it displayed the timeline of the whole original 1,5h recording from which i cut the clip out, rather then the clip i used twixtor on.
    Im really lost and have been stressing out on this for the past 4 hours. Please help.

    I tried again today, and checked for any extra frames as i saw suggested in another forum. The final clip had no red or blue frames, so i copy and pasted it on top of the song i was trying to match the video to, and then it had red and blue frames.
    Im seriously confused. Somehow the original didnt have any red or blue frames but the copy did?
    I then deleted the copy and rewatched the original again, nothing. I rewatched the original a second time, and then it randomly had red frames, seemingly for no reason at all.
    Anyone know why this happens?

    Vextor man .-.

    Good afternoon. Have you learned how to speed up video with this plugin? If so, teach me or give a link to the lesson.

    Red frames with Twixtor means missing footage. Let’s say your clip is 10sec long, you apply Twixtor with 200% speed – you will see red frames after 5 seconds.

    From my experience with Twixtor in Vegas Pro it is very unhappy if you change the clip duration after you add the effect. Shortening/extending a clip with Twixtor added is an easy way to introduce random bugs. Hence why some people suggest applying it as a media effect, but that still isn’t the perfect solution as some problems persist.

    What I sometimes do to avoid these issues is I make Twixtored files in a separate project and render them out separately. Then add those pre-renders in my final project.
    For example I need a 50% slow down via Twixtor for a 5sec clip – I drop it in the timeline, cut to where I need it to start, extend to 10sec, add Twixtor, set speed % and render.

    If you introduce keyframes where you both speed up and slow down time
    via Twixtor it’s easy to get those red frames, because you run out of
    footage or you didn’t have enough footage to begin with.

    To summarize, I suggest you:

    Drop your footage into a separate project, cut all the segments you want to slow down/speed up and make them as long as you can before you add Twixtor. Then render them out and use those renders in the main project. But I suggest you don’t copy and paste the files from one project to another – do it fresh, add from file explorer.

    And an extra tip – you can save your Twixtor settings as a preset, remove the added Twixtor effect and try adding it again (+change settings from preset) to the same footage. Has rarely helped me in the past when I encounter those red frames.

    I have run into green frames in Twixtor but on Premiere Pro on Mac. I had to turn off (or on) GPU usage in Twixtor. Not sure it helps you but thought I would post.
