When I transfer video, I get three files - m2ts,modd and moff

post #1 of 9
Thread Starter 
Hello all

I have the sony hd-12 and would like to know if there is any use in keeping the modd and moff files. m2ts is obviously the video file and is playable by vlc. What is the use of modd and moff files?

Thanks

Those are auxiliary files used by the camera and Sony software, such as PMB, to keep track of details and provide extra features. They are not needed or used by third party editing software. They are only useful to you if you use PMB as a primary transfer and organizing tool.

I would like to ask if there is any point in me downloading my digital video files from my camcorder straight to my video editing program?
Will I get the same quality etc if I download from my sd card, that I use in the camcorder and put it straight into the computer and just move the files across that way via Windows Explorer?

I believe in the digital age that data is data, and whether you cut and paste that file from the SD card or import into a video editor, the file is the file. The only time things change is if a program is converting one file type to another and re-encoding the video to lower settings.

I am still trying to be sure I understand this. Are these files just indexing items for PMB or are they required for PMB to "do" things? (you say "provide extra features"). If I delete all these extraneous files from my folder can I still use PMB to join and trim clips etc and maintain the original 1080 60p quality? The neat freak in me would prefer not to have all these files interspersed with my real pictures and movies in the folder but if they are there for a good purpose then I guess I shouldn't delete them.

Hogan is right. The video file will be the same no matter how you deliver it to your favorite third party editor.

The point I was trying to make a couple of posts back is that the file handling software that comes with your camera will do some basic editing but also does some extra "features".

I was not clear about "features". For example, the Sony PMB software can link your videos (or photos) to a google map so you can see where you took them. The camera needs to have a GPS, like in the HX9V, and the position data needs to be recorded somewhere -- like in the .modd or .moff files. Another example is the ability to use PMB to put files back on the camera so that (with the right cord) you can play it on Grandma's TV at Thanksgiving.

My Panasonic camcorder makes four extra files for each video. They end in .tmb, .pmpd, .moff and .cont. I don't know what each is for, but without them HD Writer (the Panasonic version of PMB) won't do anything.

To Hogan: PMB allows you to be very neat and tidy with your clips if you let it keep the extra files. It gives you a choice of neat and tidy file views or calendar views. The easy trimming and joining of clips in original quality seem to be unique to the camera provided software, like PMB. Apparently the third party editors have to deal with all the brands and formats so they can be a year or two behind on certain features. And, they have to be far more complicated because, to be competitive, they have to include an amazing list of functions.

To Hillarythehorse: PMB will transfer videos to you computer from either your camera or SD card. It will put them in a folder of your choice and include the extra files. The convenience level is as good, or maybe better than Windows Explorer.

To Both: Once you move your original video files with PMB, leave them where PMB put them. If you want to rename or move the original, use PMB to do it. You can use Windows, DOS, backup software or anything you want to copy those files for any use you have. All digital editing software, including PMB is called "NLE", or Non Linear Editing. It is a big deal because tape systems couldn't do it. It means that the original is never moved, modified or renamed. It is only referred to and used to make new files.

When I first got my Panasonic last winter, I ignored the software, copied with Windows and then cleaned up the SD card with a format. It seemed neat and tidy. Then, when I wanted to join a couple of clips, the software wouldn't let me because I didn't keep the extra files. I haven't tried that exercise with PMB, but I'm pretty sure it would be the same. Hogan, you could a few short clips of the dog, kid or something, copy to your computer, delete the extra files and then try to join them in PMB. If it works, let us know.

Just say you recorded 1 hours of continuous video. At 24Mbps the video will be about 12 GB in size. On the video camera the video will be split into many (4 or 5) smaller MTS files. When your use PMB to transfer the video to your computer you will get 1 MTS file containing the entire 60 minutes (and those auxilary files).

If you were to use Windows Explorer to copy the files from your video camera then you would need to join them up in a video editing application.

In terms of quality, transferring the files via PMB or Windows Explorer will not have any affect on the quality of the video.

I would recommend using PMB to transfer the videos to your PC and then delete the .modd and .moff files if you want...

This is an interesting nuance and something I should explore. Not sure whether I will use this or not, but the ability to use the camera as an "HD player" off the SD card could be useful at some point. And if you're saying that without the extraneous files, the camera won't know what to do, then I guess its worth keeping the files.

I didn't see how to put things back onto the camera, but maybe its in there somewhere. All I know is when I plug in the camera about 4 windows pop up as PMB competes with Windows to raise its hand asking me what it should do, plus there is some USB XtraSpeed thingy that came with my ASRock motherboard that also thinks the camera is a flash drive and wants to do something to it each time.

You do it with either PMB under Manipulate>Export>Media Files with the camera plugged in to the computer. Also, PMB Launcher has the same export function. I've not tried exporting directly to the SD card, only to the camera with the SD card in it.
