  1. I am trying to pass an avi through ffmpeg without ffmpeg changing it. My plan is to add commands onto this once it works correctly (such as adding padding). Unfortunately, the output is really goofed up. It almost looks interlaced.

    ffmpeg -i test2\vid.avi -vcodec copy -f avi -b 135766k test2\outfile.avi

    Original: http://www.ifthensoftware.net/invisibleman/vid.zip
    Result: http://www.ifthensoftware.net/invisibleman/outfile.zip

    From what I have read, this should have worked... Any idea what went wrong?

  2. if you're just passing it through (ie. copying the video & audio), you can't specify a bitrate, otherwise that implies re-encoding

    ffmpeg -i input.avi -vcodec copy -acodec copy output.avi

    if you're adding "padding" as in adding borders, then you have to re-encoding, and specify a codec instead of "vcodec copy"

  3. Unfortunately, it ends up looking pretty much the same. Also, Windows Media Player cannot play either result video. It can play the input video just fine though. I have to play both outfile.avi and outfile2.avi through VLC player.

  4. I remember reading somewhere ffmpeg has issues withs raw rgb bitmaps

    You can use other software to do your manipulations/editing , or convert it to a format the ffmpeg "likes". An example would be virtualdub or avidemux which can open your original file, and have simple editing functions, filters , and can encode to a variety of formats (for some reason avidemux has the picture flipped, but you can just add a flip filter, or use vdub)

  5. All right, I guess I'll just use it for the final formatting and VirtualDub for the padding.

    Thanks for the quick help! I'll be sure to visit here more often. I've been nearly pulling my hair out the last four weeks trying to get a video workflow setup. I wish I would have found this place sooner
