create AVCHD movie on flash memory

erdna · Post by **erdna** » Mon Dec 08, 2008 12:35 pm

I have no problems to create AVCHD hybrid DVD's and play them back on my Panasonic BD35 Blu-ray player. The BD35 manual also mentions the possibility to playback AVCHD movies on SCHC cards (slot available and OK for jpeg still pics on SDHC). However, when I create an AVCHD video file (.mpg) with VS12 and put it on the SDHC card it is not being recognized. What am I doing wrong?

Hi erdma,
I don''t have the BD35 but I suggest changing (simply rename) the file extension from .mpg to .m2ts and then see if it works.

Thanks, did this before, but unfortunately doesn't work.

Does the Panasonic manual say anything about putting the video in a specifically named folder on the card? I ask because with the Sony PlayStation 3, it will detect and play video in any format on a SD card, USB stick drive or DVD archive disc, but only as long as the video is in a folder labelled 'VIDEO' (all in upper case!)...

Thanks Ken, but no results with "VIDEO" nor with AVCHD" maps. The manual only mentions that SD an SDHC card can be used "recorded with other devices" Maybe I need to embed the VS12 file into the file structure and meta data used with SDHC (Panasonic) camcorders.

Hi erdna, I am trying to do exactly the same as you and am also failing. I have tried a number of different ideas but none of them works. Have you made any progress?
The VideoStudio manual seems to support the idea that this can be done but it is also ambiguous.

Just noticed this thread. I have been trying to do the same thing. That is output from VS X2 as avchd to the sd card that fits in my Panasonic camcorder and play it back on my HDTV-also Panasonic
I am wondering if the avchd format that is output by VS is the problem. I notice that when I input from my SD card the file is .MTS. Presumably the output also needs to be MTS but as far as I can tell that is not what comes out of VS when rendering an AVCHD file.Also I read somewhere that the file name (before the .MTS) needs to be maximum of 8 characters and in UPPER case.

Any thoughts appreciated.
Regards

Paul

I think it will probably want the full BD/AVCHD directory structure on the disk. Irrespective of whether you have a real blu ray writer, just tell it to create a bluray disk. When you get to the Burn page, de click the create disk box and click the create bluray folders, putting the memory stick location in as the directory. VS then creates the full BDMV,Backup directory structure for you.

Bear in mind however that this procedure will have VS re-encode the AVCHD footage to mpeg-2, so whilst it may work, it may not be what the OP is looking for.

Thank you alpine and 2dogs for responding.I did as alpine suggested but the resultant movie file that is created on the SD card is m2ts which my camcorder does not recognize.
The camera records and plays .MTS. I did try changing the extension from .m2ts to .MTS but this had no effect.
Any other thoughts would be appreciated.

I was really responding to the OP.

It seems strange if it's just mpeg-2 that the stream files produced on the image have an m2ts extension, which is normally reserved for avc.

Edit: I've forgotten that Bluray is less advanced than HDDVD was: I think they do allow mpeg-2 in the container, because of the shortcomings in the early Bluray products. I assume that VS11.5 only allows the old style stream. Is this also true of XS?

A couple of thoughts ... though I hasten to add that I don't have an AVCHD camera so have not tried them in practice.

First, does the 'editing' software which came with your camera (e.g. if you have a Panasonic, then the software would be HD Writer), have any instructions which might cover this situation? Or can you input m2ts avchd into the program and output mts?

Second, if you created (as I have) AVCHD hybrid discs, then a Blu-Ray-type BDMV structure is created on the standard DVD. The AVCHD files are contained in the STREAM sub-folder. They are all m2ts using the H.264 AVCHD codec. However, I wonder if you copied one of these to your hard disc and renamed the extension to .mts, whether, after exporting it to the SD card, the camera might be able to see it...

I know simply renaming the extension from VS's direct output of an AVCHD m2ts has not worked. But I am wondering whether the processing to an AVCHD disc might make a difference. It would be a long work-around, but it could be worthwhile at least to try as an experiment...

Yes, since HD mpeg-2 files recorded by HDV camcorders have an .m2t extension.

It may be that since Blu-Ray disc capacity is higher, it made high bitrate mpeg-2 feasible. The default Blu-Ray bitrate in VS is 35000kbps VBR, and the maximum allowable appears to be 60000kbps. By contrast, the HDV standard, arguably developed in conjunction with HDDVD, allows 25000kbps, albeit using constant rather than variable bitrate.

If by this you mean mpeg-2 compression, then unfortunately it is!

I just wanted to add my voice to the chorus. I am also tring to move an X2 created video (eval copy) back into my camcorder. The HF10 uses .m2ts as it's native file format. I generated a video in X2 using the AVCHD template, renamed the file to xxx.m2ts, and tried to use the bundled ImageMixer 3 to copy the file back to the camcorder's internal flash memory.

I imported the video into an IM3 library, but when I tried to upload it, IM3 wouldn't let me (the video was not displayed as an option for uploading).

As IM3 does give you info on the files, I was comparing the X2 generated file to a file created by the camcorder. There are bitrate differences. I'll try tweeking render settings and see if that makes any difference.
