accidentally deleted a movie with important footage on my macbook. is there any way i can recover

For clarification: Is the "Movie" that got deleted an iMovie Project? (Sometimes projects are referred to as movies.) Was it a movie that was exported from an iMovie project? Or was it original media that was imported to your Mac from the SD card?

Had it been transferred to the computer, or was it just on the SD card?

If on the SD card, go to the mfg's website, they may have recovery software.
