Transcode DSLR video prior to editing question

    I am just getting back into video after a few years away and I need to get
    back up to speed with the new file formats.

    I have read a number of times that it is helpful to transcode the H.264
    files created with a DSLR into another format to make editing easier. I have
    some files from a Canon 60D which will be processed using Premier CS5 on a
    Windows machine. The movie record size was 1920X1080 30fps. There are a
    number of formats to choose from and I have no clue which to choose.

    I should also mention that that footage will be combined with other files
    filmed with a Canon HV30 (.m2t files) and the camera was set to record HDV
    (PF30). Should anything also be done with those prior to importing?

  2. Premiere CS5 (along with just about any other fairly recent editing
    software) should be able to handle even high-data-rate 1920x1080-60P
    AVCHD/MP4/H.264 video files. I use 1920x108-60P 28Mbps and 50Mbps
    files now, and Sony Vegas Pro and the cheap Vegas Platinum have been
    able to handle them from the beginning. The bottleneck can be in the
    computer hardware, and this limitation can be alleviated by using
    either proxy files (which I dislike, since they are lower-quality
    than the source files making image-adjusting more difficult) or
    intermediate files (but these take time to make and require MUCH more
    storage space since they are considerably larger than the originals).
    At first I used lower-resolution file playback in Vegas (switching
    to full-resolution when needed to work on filtering) or making
    temporary RAM preview files for smooth playback of brief parts. The
    solution, though, was to build a much more able computer, including
    a very good GPU-equipped video card and a fast overclocked CPU (the
    CPU made editing easier, and the video card rendered the video MUCH
    faster than the CPU alone could). I used an Intel i7 2600K processor
    at 4.4 GHz (with a better-than-stock air-cooled heat-sink added),
    and this is still a good choice since it is an easier processor to
    overclock than later versions which have greater heat limitations,
    and it is not terribly expensive. For the video card, I used a card
    based on the 480-core nVidia GTX570 (many are available, but I liked
    the EVGA 1579-AR, since that "AR" included a lifetime warranty...;-).
    With this computer, with software that can make use of the video card's
    GPU, the video file types I want to work with became practical to
    use with without needing to use proxy files or intermediate files.
    That depends on the editing software. With Vegas, just about anything
    can be placed on the timeline in combination with just about anything
    else, and all can be exported as just about any file type you want
    (including custom variations). BTW, I was in mid-shooting of video
    for a project with HDV when I bought a camera that shot 60-P AVCHD
    at 28Mbps. I was able to put both file-types (plus stills) on the
    Vegas timeline, and export both 60I 40Mbps Blu-ray and 60P 50Mbps
    MP4s (for archiving). CS5 may be able to do the same...
