Problemw with multisegment Sony-style MTS files (AVCHD, h.264)

[codeguru]

hi,

I'm not sure if my post is right here.... I own a Sony HDR-CX 690
This is a cam that writes on SDHC cards, can do plain old SD (720x576 in i50) and has three HD modes: 1080p50, 1080i50 and 1080p25
The HD resolutions are AVCHD, the SD resolution is encoded with Mpeg2

When a clip produces more data than fit into 2 GB, then the cam generates a second, a third.... mts file. Some programs directly support it like the Magix Videodeluxe (18) or the Pinacle Studio, but the transition between 2 Blocks shows artifacts, some black frames or other weird stuff.

On the cam is a programm called PMB, but that works only over USB, and that is terrible slow - and basically converts the mts files in one big m2ts file which doubles the amount of data with the poor USB performance of the cam, which does about 3 MB/sec - also without the PMB, just doing a copy of a file in the cam to my laptop from the USB connected cam

The PMB refuses to read the SDHC card when it is in my laptop - there the card could be read with 20 MB/sec.

Are there any other tools they can do that? Or are there cheats to tell the cam making "clean" mts files?

Have you tried indexing with MeGUI? It might pick up automatically that there are various connected files. (Check the guides I wrote in this forum folder about importing DVDs or Blurays for some details on this and then getting the resulting AVS file into your editor).

In the worst case scenario, you could manually create an AVS file that will join them all together, and then edit based on that.

You can also use TSMuxer to join the files.

Normally a simple COPY /B file001.mts+file002.mts+... result.m2ts should do the trick. Programs like Magix and other video editors tend to search for the first valid video frame of each segment and thus they'll discard some "unneeded" packets ;)
