First off I don't really know much about digital video or editing. My experience revolves around recording sporting events on my tv tuner and picking out the highlights to post on youtube or cutting out commercials and saving the file on a big old hard drive for later enjoyment. I've used different formats in the past to save the files including some like the vcr format of the old ATI tv tuners. I quickly learned I couldn't play these files anywhere else and went back and converted to mpeg2 which seemed like a good enough standard format to me. Now I'm recording in games in HD and the mpeg2 files are up in the 20-30GB range. I have an HP MediaSmart server which automatically converts to H.264 files. I'm wondering if I should just dump my mpeg2 files once they are converted. Benefit of the H.264 file seems to be slightly smaller file size. But with cheap storage prices this might not matter so much. No more "interlaced" looking video. Apparently it's better for streaming to PS3 and other types of devices. I just watch them on my computer so I don't really care. It seems to take a while to convert to H.264 but I let my HP home server do it so it can take 20 hrs and won't affect me. Benefit of mpeg2? I can edit pretty quickly in mpegstreamclip....what can I use for H.264 files? It's the same format as the source (right?) so I haven't lost any "quality". This is probably the biggest one for me. I don't want to keep the photograph and throw away the negative if you get the analogy. Would I be losing any flexibility by moving to H.264 format? If 5-10 years from now there is a new/better format would I be kicking myself for dumping the mpeg2 files? Overall I'm trying to simplify my archive and not have so many different formats cause finding the proper codec in the future can be a problem.
