I am planning to transfer a number of old VHS tapes, and I was wondering what the best format is for import into Adobe Premiere Elements 8. Here is a brief summary of what I think are the three leading contenders:
.vob - Typically a transfer service will transfer your VHS tape to a DVD. PE8 will read and use these .vob files. The picture quality is OK, but because of the high degree of compression some quality is lost.
.avi - This is the format that Adobe recommends. Each frame is separately compressed. The quality seems very good.
.mov (H.264) - A more modern way to compress the data. However, I read on an archived Adobe technote: "MPEG files don't lend themselves to editing because the video frames in an MPEG file aren't self-contained. That is, any given video frame contains only the information that has changed from the previous frame. During editing, a previous frame required to fully decompress a given frame may not be present, resulting in poor quality of the final rendered frame." I have used high quality .mov files in the past and have not noticed any loss of quality.
If the transfer service can produce all of these formats, which one should I select?
In terms of file space needed for a converted VHS tape, .vob would use about 4 gigs, and .avi and .mov would use around 15 gigs of space. Less compression is better, so I would think that .vob would be the least desirable option. The decision is really between .avi and .mov. File size is not really an issue these days because of the low cost of disk space.
