mpv’s forced to transcode
Hi,
I have some mpv/mpa files I get hardware encoded from another company. Encore 2.0 ALWAYS forces a transcode even when I select “don’t transcode”. Also it won’t read the mpa’s untill I convert them to wav’s.
All the files are DVD compliant. The mpa’s are PCM 48K/16bit and the GOP’s of the mpv’s are set up correctly. The technician that does the encoding has been doing this for years and never has issues. DVD Studio Pro will take the files with no transcode and no issues. I called Adobe abd they said Encore 2.0 does support mpv files so what gives? Am I mising something?

Frame size and frame rate of the .mpv files, please?

Thanks.
1. As you have discovered, nothing obvious points to what is causing the problem, so digging deeper is needed.
2. What is the peak bit rate of the files?
3. Just for clarification, what is the GOP structure?
4. Are the combined file sizes too big for the project, i.e., is there any chance you are trying to put more than 4.7 GB into a single-layer project?
5. If you set the transcode settings to “Don’t Transcode”, what indications are you getting that Encore is transcoding the video assets?
6. Just for fun, please try changing the extensions on the files to .m2v for the video and .wav for the audio. Don’t make any other changes to them and then try them again in Encore.

Jeff,
I did try to change the file extension to m2v and it made no difference. I know it’s transcoding the files because Encore says “transcoding video” and I watch the progress bar take a few minutes to finish. Also the end product shows more artifacts than coming out of DVDSP. It’s only a 2 minute video so file size isn’t the issue.
As far as GOP structure goes, I believe it’s 15 frame GOP. I actually have gone over this with the tech who does the encoding and they are DVD compiant files. I’m not sure what the peak bitrate is. Isn’t there afree download somewhere that will tell you?
Anyway, I’m stumped I like Encore, but if I can’t use hardware encoded files my clients demand, I’m gonna have to go to DVDSP for good.

OK so I made a new project in Version 1.0. Everything worked OK. I’m starting to think There’s a glitch somewhere. I already re-installed the program however so I guess I’ll try it on another machine.
