I accidentally deleted a video file I was working with because apparently I forgot to check Copy to Library. I only dragged it to the trash and deleted it, so I am hopeful that Data Rescue 5 will be able to recover it, but in the meantime while I am trying not to panic, does anyone know of a way to make a new file from the Render Files??

Render files cannot reproduce the original video as they only optimize the effects stream of a clip to provide smooth playback. Looks like your options might include Data Rescue, Disc Drill or other recovery apps. This assumes it was copied from the card to somewhere on your computer before you deleted it. If you deleted the clip only from the timeline and you imported as "leave in place", then the actual clip didn't get deleted, only the non-destructive version of the original file did (if I understand your post correctly). If you go to the FCPX library in the finder, right click on it and choose "show package contents" you should be able to locate the event the clip was in. In that event will be a folder "Original Media", and in there would be the original file (if "copy to library" was used, or a link to where the file resides (if "leave in place" was used).
Creating history....one edit at a time !

Thanks for your reply, although it is bad news. I did not just delete the clip from the project, I deleted it from the SD card and then emptied the trash. I always select Copy rather than leave-in-place, but somehow this setting got changed & I did not realize it.

I have tried Data Rescue & Stellar Phoenix Photo Recovery. Both see the file, but are unable to recover it. I am currently scanning the card with Stellar Phoenix Data Recovery but it probably uses the same techniques of the Photo version so I am not hopeful. I will try a few other products & then consult with a data recovery specialist if nothing else.

Any recovery software suggestions, Mac OR Windows, gratefully accepted. I wonder if the problem is compounded by the fact that the card is formatted ExFAT & the file was trashed on a Mac. No data has been written TO the card, so I have hope it can be recovered.

If the card was not formatted and no further writes took place, there is potential the data might be recovered. If recovery apps don't work you can send it to a commercial data recovery company. I used this company once: www.securedatarescue.com

Best Buy also contracts with a data recovery service but it's even more expensive.

I can tell you from experience, paying a ton of money to those recovery companies usually doesn't result in much more data retrieval that what you're getting with those apps. Just my two cents from my extensive experience with that. It depends on what that footage is worth to you...

Another vital point is you should have a written agreement with the company for amount paid vs results achieved, and the meaning of "results" should be defined.

E.g, the few times I've done this, I told them this is video, not a .txt or .doc file. A document might be valuable even if it has garbage at the end, or a few odd characters. By contrast a partially recovered video file may not play. It does me no good if they recover non-playable fragments.

For some recovery companies you pay nothing if they recover nothing. With others there's a low cost for the attempt but if "successful" (whatever that is) then you pay more.

All that should be defined in writing before going forward with the transaction. In my limited experience they were not successful, but that was a reformat case not a delete case.

Re reconstruct from render files, this would be difficult. While internally those are encoded ProRes 422, they are not arranged as regular files but split in frame-range batches across many files. You also don't know if the entire media file is rendered.

If the OP had Time Machine running, it might be recoverable from that.
