I have a Canon HF100 camcorder and I use Premiere Elements 7.0 to edit. I can't edit in HD because my PC can't handle it. However, I found that if I export the AVCHD files from Premiere it compresses it to AVI format. If I import the AVI file then I can edit with no problem. I'm wondering if there's any way to preserve the HD format after I edit the AVI files. Or, is there a better way to get around my problem of editing AVDHD files? Thanks very much.
