Editing .m2ts files - solution #1

[Jasper Hendriks]

For anyone interested I'll post a solution which makes ables you to edit .m2ts (1920x1080) files a lot easier.

This is how I did it:


From the Menu:

File->Insert Media File to Timeline -> insert Video

Now select the .m2ts file, Next:

Select Create Video -> Blu-ray -> PAL HDMV 1920
Select Options from the dialog box
Unmark Perform smartrender
Unmark Perform non-square pixel rendering
Select new filename with .m2t extension


Result:
A new MPEG2 file which is about 1.8 times bigger in size and still looks great and is much easier to edit.



I noticed sometimes when playing the file it showed some jerky noise at the start, it looked like some buffer-initialisation bug caused by the generated MPEG2 file.

Yes. That's all logical. But do you then reconvert the mpeg-2 files back to AVCHD mpeg-4 after editing? Otherwise, it seems to defeat the purpose of having the more highly compressed AVCHD format in the first place i.e. high quality video in considerably smaller files...

[Jasper Hendriks]

I dont need reconverting it back, the conversion process is like unpacking the frames from the more compressed H264 codec (not mpeg-4, this is much lower quality video) and putting them into another more standard MPEG2 lower-size-compression.

Yes. I understand that. But what is your ultimate intention with the video? To downconvert to a standard definition DVD? Burn a Blu-Ray disc (which would of course accept the Blu-Ray HDV mpeg-2 files you have now created)? Create an AVCHD hybrid disc on a standard DVD for playback on a Sony PlayStation 3 or other Blu-Ray player rated to play hybrid discs?

If in fact you intend to burn a proper Blu-Ray disc, then that is of course fine. But of course, you can also burn AVCHD to a Blu-Ray disc, and given that AVCHD is a much more compressed format, you would fit a lot more AVCHD on a Blu-Ray disc in full high definition, than you could the HDV mpeg-2 video you have now produced.

I was looking at my future viewscreen when using AVCHD but it's looking great already on my 24 inch monitor except when I used the laptop for playback.
