File Uses Unsupported Compression Format
I did some video conversion for a friend recently, to convert home video footage he had put on his computer. The program he used had changed the format and compressed the video data as part of the transfer process.
My friend wanted to edit the files in Adobe Premiere 6, which was bundled along with some hardware he bought. You know the kind of stuff, birthday parties, Xmas, holidays. Cut out the usual poor footage that tends to fill so much of amateur home video efforts.
I did the conversion using Virtualdubmod and an AC3 audio codec. I'll post the process in a future blog at another time. Anyhow, back to the problem at hand.
After the conversion of the video into DV-AVI format, I tested it in Premiere 6 and all seemed fine. I was able to load footage into Premiere and mess around with it. The process worked. A total success.
I delivered to footage on hard disk, and tested it during the handover. It worked fine.
About two or three weeks later, I got a call advising me that video editing was not working. Huh? How did that happen?
I collected the hard disk containing the video, hooked it up to my machine, it worked no problem. Hooked the disk up to another machine. Fired up Premiere 6, then:
Premiere 6 Error: File Uses Unsupported Compression Format
Huh. Whats happening here. How come it works on one machine but not the other? Something is different.
I did a search and discovered it was down to the audio codec used in the conversion process. The codec was not installed on the second machine at my place. The codec was not installed on my friends machine either.
I downloaded and installed the codec on the second machine and Premiere 6 worked first time.
If you get a similar problem, you'll know how to crack it.
Here's a link the codec I used. Only useful if you used this codec as part of your format conversion otherwise its useless: AC-3 ACM Codec.
Hope that helps.!
