What’s the best way to transfer video from a canon AVCHD canon HF m31 flash memory camcorder?
Question by Andy: What’s the best way to transfer video from a canon AVCHD canon HF m31 flash memory camcorder?
I am not an amateur at this i’ve been editing for years. I recorded a musical for my sister that is two parts, the first half and the second. I can see on the camcorder that it is only two scenes which is correct. However, when I transfer my video using Windows, it automatically splits it into multiple scenes, each that are around 1.9gb in size. When i piece these together in Adobe Premiere Pro, there are about 3 dropped frames at the start of each of these created “scenes.” I know that it must be the transfer that messes this up because when i plug my camcorder into my TV, everything plays perfect no problem. I don’t have the included software that came bundled with the camcorder and there is no way to get it because apparently it doesn’t exist anymore. You can only download an “updater” from the website in which you need to have the software already installed which I don’t because i had to have windows re installed a while back. Is there any other free software that won’t split up these two clips into multiple or anything I can do? It’s a flash memory camcorder, so you can’t “capture” the video with any software. My computer can handle it no problem. i7 processor and 8 gb of RAM. Please HELP!!!!
It’s a flash memory camcorder so you can’t use the capture feature with premiere. It says you are supposed to just transfer the files to your hard drive but I have done this and i get the dropped frame issue. These “1.9gb size scenes) it makes, each one starts off with a frozen frame for about 2 or 3 frames then continues just fine. I don’t know what else to do. I know the video files are okay because I can plug my camcorder into the TV and view all the videos no problem. Everytime I try transferring the footage over the same thing happens.

There are two ways to edit AVCHD video.
You found the first method. Copy the MTS files from the camcorder to the computer and “piece them together”. Your observation of the 2 gig file size limitation is known and is basically required by certain operating systems which cannot deal with large file sizes. Many times, this method requires transcoding (converting) the copied MTS files into a more useful file type and uncompressed format for the editor to deal with.
The other method generally means connecting the camcorder to the computer with a USB cable, putting the camcorder into “Play” or Computer mode and doing exactly what you say you can’t do – but this does assume that the video editor is AVCHD-file capable. During that “import” (capture) process, the camcorder’s electronics are used to decompress the video file data stream and the video editor can pull the video into whatever video type it likes to deal with. Sony Vegas and Apple iMovie and Final Cut can do this – I was pretty sure Premiere could too – though not know which version you are using makes it challenging. When the video is imported/captured this way into the computer, the “seamless” video you want should happen.
The problem you are encountering with the method you are using probably has to do with the way AVCHD video compression happens.
Frame 1 = base
Frame 2 = what changed from frame 1
Frame 3 = what changed from frame 2
Frame 4 = what changed from frame 3
Frame 5 = what changed from frame 4
Frame 6 = what changed from frame 5
Frame 7 = what changed from frame 6
Frame 8 = what changed from frame 7
Frame 9 = base
Frame 10 = what changed from frame 9
Frame 11 = what changed from frame 10
Frame 12 = what changed from frame 11
Frame 13 = what changed from frame 12
Frame 14 = what changed from frame 13
Frame 15 = what changed from frame 14
Frame 16 = what changed from frame 15
Frame 17 = what changed from frame 16
Frame 18 = base… and so on…
If the file size limitation happens at frame 4, then frames 5, 6, 7 get confused. If the second method (importing/capturing) is used, then the camera’s file system working with the editor are able to piece the video back together as a contiguous file and the “dropped frame” issue should go away.
If you continue to use option1, then be sure to use the highest quality capture setting in the HF M31. This way, there is less compression of the captured video so more of the frame is available following the base frame. Because of the reduced compression, there will be more of the segmented files.
