I recently purchased a small camcorder (Insignia NS-DV720P) that records HD 720p digitally to flash memory, but no editing software that I have tried can edit the files (AVI) properly. I want to do simple edits like croppng and cut/pasting certain pieces together, but nothing that I have tried does this. Most programs can't even open the file, and the two that did open did not output the file correctly, either saving to a different AVI format where the file size for a 5 minute video was 2+Gbs after saving, or saving with corruped audio and some scrambled video. Does anyone know of any video editing software that can edit HD video properly? Thanks! I have tried: Blaze Media, Boilsoft, ImToo, Movavi, Quicktime, Xilisoft, and probably a couple others I have forgotten.
