10.0e and rendering .avc files (and playback .avc)

Shield wrote on 7/6/2011, 6:08 PM
Editing raw .mts files from a Panasonic GH2, 24Mb/s 24p mode. When I export this as a .avc file (video only) my choices include 16,000,000 and 26,000,000 (the latter appears to be a new option for 10.0e. Anyway, I get "an error occurred while creating the media file xyz.avc. The reason for the error could not be determined."

I can manually type in a bitrate, and for me it give this error message until I back it down to 21,500,000.

Any ideas? 21.5k and below seem to work. I've also tried (just for fun) exporting with the .MVC option, and it actually works, but then if I load this mvc file into the trimmer it plays in super-fast speed.

Also, should I be able to play back raw .avc files? I've tried a myriad of H264 decoders and playback software, including Windows Media player classic home cinema and VLC and I get "Cannot render the file". I swore I used to be able to play back .avc files.

I can play back AVCHD files from my Sony Camera using Windows Media Player, VLC and Media Player Classic Home Cinema. Note that VLC has its own decoders and doesn't use anything else you install. Don't know about Media Player Classic.

Raw .avc files? Not mts, m2ts, et al. But raw .avc. Can you play those?

Sorry. Where do raw AVC files come from? What makes them raw? You mention raw mts in your first post.

The files on my camera are called .MTS because of the file system limitations, but they are identical to the .m2ts files I get after transfer. Long files are segmented into 2GB (?) chunks of course but concatenation puts them back together again.

I cannot write directly to .m2ts files (video+audio) because I only have the option of 25FPS (Pal) or 29.97 (NTSC). My files are 23.976 (24p) and I want to keep the framerate the same. So I have to export the video first as an .avc file (There is a blu-ray template built-in for it) and then export to .ac3 for audio, then I mux them back together with TSMUXER.

I'm surprised no one here has commented about the lack of ability to render to 26Mbps .avc files.

26 Mbit/s (more precisely 25,99 Mbit/s) is only available for 1080p50 and 1080p60 video. Your limit when rendering to 23,976 is 21,99 Mbit/s.

You can also select MP4 as file format to render both video and audio. But I'd recommend to remux the file with tsMuxeR anyway.

Excellent to know that! So then, 2 questions. Why is 21,99Mbit/s the limit when my camera does it in 24 Mbit/s? Also, why is 29.97 and 25 FPS the only choices for m2ts output? I would really love a 23.976 option.

Thanks,
Shawn

Sorry, I don't have an answer to these questions.

Why isn't MP4 an option for you?

I want Dolby Digital Audio, not AAC.
