Hello,
I managed to collect an amazing set of videos that I'd like to use in final cut pro for a video project. How can I convert these vdjsample videos back to their original format that I first imported them in?

hello
it seems to me that this is impossible
at one point at the time we could convert vdjSample to .mp3 but now it is taxable and even less to convert vdjcahe

Presumably you still have the original video files before they were converted/edited in VDJ?

Why do you think that?
I'm not aware of anything changing, and the audio files saved by VDJ are just OGG files with an extra bit of data added to the start. If you remove that extra data then they could easily be converted from OGG to MP3.
Therefore it would be worth checking to see if the same is true of video files.

he says he would like to convert the vdjsample videos to mp4,mkv for me this is impossible.

He would need to look at the VDJ video file to see if it's converted in a similar way to how the audio files are.
Chances are that it uses the same method, so it would just need the header removing, and possibly converting back to its original format.
It's not impossible, and I'm sure there are some members here who could write a utility to "un-VDJ" the file(s).
I've never been happy about VDJ using its own format for edits, as I'd love to be able to use my vast sample collection in VDJ but doing so would create thousands of duplicate files on my drive (original format and VDJ format).

Quick look: Recorded samples are only MKV with extra VDJ header:
Media info gives correct infos
00: "VDJ\0"
04: a 4 bytes int ???? Version ?
08: a 4 bytes int Index of mkv or HeaderSize
...
Index: 1A 45 DF A3 A3 42 start of MKV signature
remove leading HeaderSize bytes and rename .mkv then the will file will play on any media player

By putting a sample file in a vdj deck and saving it as mp4 this is 100% feasible.
But we cannot convert a vdjSample file whatever the format

Who is "we"? It can be done, I've done it in the past (with audio files). Also, see the post from Nicotux...

If I had the originals I would not need to convert the vdjsample files back to the original format. Then I'd just have two copies of the same file and hopefully be banned for life from vdj forums for wasting peoples precious time.

You're brilliant! How do I remove the VDJ headers? I opened the vdjsample file in my text editor on Mac but the language is computer code so I don't know which bits to remove. I do see a few words in english at the top but they just point to the file path.

Ahh a HEX editor! I searched for that string that you listed 1A 45 DF A3 A3 42 but it was not found in the test file I loaded when doing a HEX search.

YES!!!! I got it! So the string you entered was a bit different for me since this file was originally an Mp4. I did a search with every combination of the value you entered starting with "1A" then "1A 45" then "1A 45 DF" etc. until I found a combination with only one instance in the entire body of the code. My string was just 1A45DFA3. I deleted all of the HEX code in front of that number then saved the file. Next I renamed the file extension back to its original mp4 and voila it plays back in INNA. Thanks again for the tip!

The only extra step I had to take was to do a lossless remux using Mp4Tools. If I use the HEX edited renamed version and try to drag it into Final Cut Pro it won't accept the file. Doing a lossless remux back to mp4 fixed that. I hope this helps anyone else:-) Thanks to everyone who contributed to the solution!
