Just installed Movie studio platinum 14 build 148 on my new Win10 computer. It worked fine on the old computer but slow. When I try to add a music track in M4a format I get "Warning: An Error occurred while opening one or more files. The reason for the error could not be determined." if I click details, I get "File D:\Music\_DJI Music\ABOVE THE CLOUD_10s.m4a could not be opened."
The file can be opened and played on the computer without issue... just not in MS14P. build 148 Help!!!
M4A is an Apple proprietary file format and it needs Quicktime for decoding. If Quicktime is already installed on your system you would need to transcode the file before importing into Movie Studio.
Edit:
I forgot – while the file format would enforce Quicktime for decoding, the audio coding is just plain AAC. So a simple re-wrapping to MP4 (with an audio passthrough) makes such files being compatible to Movie Studio. Tools like FFmpeg allow for re-wrapping.
QT was not installed. I installed it and MSP14 seems to be working with M4a files now. Perhaps a better message might have made this easier 😎
Still some issues. Opened an old project. I moved the "data" drive (D:) from the old computer to the new, so it is the same... no changes. Yet when I open existing projects it can't find some of the files. If I locate the file and save the project, next time I open it finds everything.
One last issue - I opened one old project, I can play the video BUT the background proxy build gets an error.... "Error 0x80070026 (message missing)" and the background proxy build quits.
When a file path relative to the project file changes, then it is just the way it is that it needs a re-define of the path.
Not sure what you mean by "proxy" here. Are these UHD or 4k files and Movie Studio builds video proxies for them? Or are these eventually WMV files and it's the audio proxies which causes the trouble?
First I'm a pro photographer, but a dunce on video. The captures were mostly done with my DJI Mavic drone and it can capture 4k. Also my Samsung Note8 can capture 4k (I think). I found working with 4k so slow that most of the time I just capture 1080p. So yes some of the files are 4k but it is often a mixture. File format is mostly MP4. I can also on the drone do mov. any recommendations?
Then you should check how much free space is on the drive/partition where your 4k source files are. The proxy files may need about the same space as the source files, maybe even more. And my guess is that error message may tell us there's not enough space left for the proxies.
Also do note that music files from iTunes have copy protection built into them such that they will throw up an error code if you try to use them in a video project.
So if this is a song you bought from iTunes, that could be a major contributing factor to your problem.
