It can be tricky, especially on Mac, to trim AVCHD videos (.MTS or .M2TS) without transcoding the videos. Most tools, such as Adobe Premiere, Adobe Media Encoder, Apple Final Cut Pro, and most sharewares, will require to convert before trimming, which is a slow and loss-full process.
On Windows, Canon provides a tool to directly trim .M2TS files without any re-encoding. However, on Mac it is more tricky, and I had to do some digging and spend some $ to accomplish about the same thing.
After much research, I found a way with two softwares:
- ClipWrap ($50): This allow you to convert your .MTS to .MOV without any re-encoding (just a “rewrap” as it is called). In short, it’s super fast (almost as fast a coping the file), completely loss-less, and you can play the new .MOV file with Quicktime.
- MPEG Streamclip (fully free): This free software allow to open video files (.mov, .mp4), trim them, and just save them (without transcoding). Make sure to use the “Save As,” as the “Export…” will do the transcoding. I wish it would support AVCHD format so that we would not need ClipWrap.
If you have done a live Vista update lately you might get the following error when starting your Adobe Premiere CS4 application:
“Premiere Pro has encountered an error.
with one button “continue”.
Once you press the “continue” button nothing happen (and the Adobe Crash Report shows up).
Adobe will probably (and hopefully) solve this problem, but in the meantime here are 2 workarounds:
- Start Adobe Premiere Pro as Administrator (right click on the .exe file and select “Run as administrator“.
- Or Turn Off User Account Control
Hope this help.
I think the problem is that Adobe Premiere Pro CS4 does not support very well the Vista User Control Account system. I usually have it turned off, but my last Vista update turn it back on automatically.
Here is the forum link for this issue: I get an error when I open Premiere Pro (CS4)
Adobe CS4 Premiere is not very well optimized for AVCHD editing/playback. Adobe points at the format, and users tend to point at Adobe. Personally, I think that the software is a little heavy, but I think that Adobe could make an effort to optimize it (other AVCHD players, such as the ImageMixer coming with the Canon HF11, are playing the .m2ts or .mts files just fine). See Adobe Forum on the AVCHD Playback.
However, I did find an [obvious] trick (on Windows) that makes the experience much better.
Just upgrade the priority for the process “ImporterProcessServer.exe” from “normal” to “high” in the Windows Task Manager. Simple, but it does make a nice difference (at least for me).
I still hope that Adobe will optimize their AVCHD playback/editing in a future CS4 update (it would show that they are listening).
