Track Matte Problem – Can’t Choose Target Video From Option List
Hello everyone,
Having completed my narrative-edit I’ve gone back to try blurring out car vehicle licence plates using the Track Matte/Mosaic effect for the first time whilst following the official Adobe Tutorial. However, having followed this step-by-step guide by duplicating the video layer, overlaying it, applying the Mosaic Effect, overlaying a Track Matte layer (reduced to a black square) I then face the same issue.
When choosing from the Track Matte Key options/pull down menu which lists ALL of the video tracks that sit above my duplicated video within my timeline I can ONLY choose from videos ‘7’ upwards and NOT the Track Matte video track ‘4’. Out of curiosity I’ve tried to choose other tracks to see what the issue/problem might be but the effect will choose video 7 (automatically) when I manually try to choose videos 4, 5 or 6 but it does accept videos 7, 8 or 9 (which are Adjustment Layers and Cinema Bar Overlays).
Many thanks for your advice and feedback in advance.

Explain what you mean by “reduced to a black square”.

Hi and thanks for your reply.
I’ve reduced the pixel count/matte size to 300×300 (solid black) which presents itself as a black square overlaid on top of the duplicated video layer beneath it.
Thanks.

Try just making the matte with the Title tool. Draw a box at whatever size you need. If you keep it white use the luma matte setting with the Track Matte Key. If you make it a color use the alpha matte setting.

Thanks for your suggestion and I will follow your advice. My concern and reason for posting was to solve this problem/issue which doesn’t make sense to me and will cause further problems at later stages.
