    Hey all,

    Am trying to do the ol’ Bob Dylan – Subterranean Homesick Blues card trick. In other words, am trying to track some cards being set down so I can replace them and add animation on to them.

    Am having a very difficult time getting a clean track of the card using AE and/or Mocha AE.

    Am sure I set it up all wrong. That is a given. Was a last minute change on set to use these cards. Did my best to set myself up for success in post. Not so much!

    Anyway, can anyone offer any suggestions/tips on the best way to track these cards so i can replace them? I think the motion blur on the card is making it nearly impossible. Mocha loses the markers every single time. I tried to roto out the card and then track it but am having the same issue.

    ANY help would be greatly appreciate.

    Thanks so much for taking a look.

    The tracking markers don’t seem too helpfully positioned, it looks like a by hand track job near the end sections of card removal. The fact all the cards are green isn’t too much of a problem, your masking will just have to be on point.
