ProVu is my viewer of choice when managing multiple codecs and formats in the field and in the studio. Whether I'm working on network TV series, short films, commercials, cartoons, or documentaries, ProVu always seems to find its way into my workflow for quickly checking my shot materials. Typically I use ProVu in conjunction with ShotPut Pro....I have tried just about every other data management solution on the market today, and I always come back to ProVu and ShotPut Pro. The ease of use and reliability of this software can't be beat. There is nothing that comes close at this price point.
