Problem with Prodad Rotopen

[gary1988]

I have edited a map and a train image which is fine when applied and the preview works fine but as soon as I create the rendered video the path and the train image have moved to a position further down the map, and I have no idea how to see the path and train image in the right place. Are there any fixes???

You will have to match the frame size and aspect ratio of the project properties with a share preset. If they don't match, the RotoPen path won't be where you expect it to be. By default the project properties are 720 x 480 with a 16:9 aspect ratio. There's a share for DV Widescreen which has the same properties. Unfortunately, once you have used Roto Pen with a particular set of properties, you can't change project settings without throwing the Roto Pen path off-track.

Having just the aspect ratio matching is not enough to keep the path on-track. The frame size needs be the same, probably with a few exceptions.

I would create a standalone HD project just for the RotoPen sequence, and share to a matching share preset. Use the resulting video file in your main project. That way the path won't be disturbed when you upscale or downscale relative to the project properties.

Thanks. That cleared my mind. What are the parameters for a standalone hd project for rotopen and how have we to manage settings?

Hi franapo

Welcome to the forums

I think Kingston is referring to setting the project properties to match your video files frame size.
So if HD your video is probably 1920 x 1080

Video Studio by default uses standard definition sizes, however we can manually change by editing the project properties to Avi similar to:-

NTSC non-drop frame (30 fps)
Microsoft AVI files
8 bits, 1920 x 1080, 30 fps (use 25 for Pal)
Upper Field First
Microsoft Video 1
15 Key frame rate:, 75% Quality
PCM, 44.100 kHz, 16 Bit, Stereo

I am sure Kingston will clarify

Hallo! Great! I started a new project setting avi 1920x1080. Then created a new video file blu-ray with my map rotopenned.
Inserted in my big video file and rendered. Great!
