Hi,

I have been slowly transferring all my old MiniDV videos to my PC,....I have been converting to AVI, figuring that it is better to preserve them in the least compressed (?) file, .....each file is about 13GB (!) per each hour of video, which is quite large. Is there any advantage to continuing to transfer to this large AVI format, ....i.e. is there any disadvantage to converting to a format which is smaller in file size? Once transferred, I transfer these files to external usb hard drives.

The advantage to transferring your miniDV videos in the AVI (DV-AVI codec) at 13 GB an hour is that the footage is the exact same quality as what's on the miniDV tape.


It's also in a format that is easily editable and almost every video editing application will be able to accept and use this file.


Once the AVI files are on your hard drive, you can then compress them into another codec at a lower bitrate to make them smaller. DV-AVI files are 25 Mbps.

You might want to look into the x264 codec. It's a modern codec which compresses footage very well. The issue when converting a file into a different format (and particularly when reducing the bitrate) is that the picture quality is reduced. Depending on the settings, this reduction may not be visible.


External hard drives are cheap. You can get 1.5 TB 3.5" external hard drive for about $90 - that's over 100 hours of DV-AVI footage. With hard drive storage costs only to become cheaper, I would recommend leaving your footage at the original size/quality.
