  • How to crop a quiktime movie?

    Hi all.

    I’m cutting a show on Avid. It’s a film show, aspect ratio 2.35:1 flat. We’re trying to figure out how to compress clips for web delivery. Here’s our workflow so far:

    Export from Avid full size with same as source compression.
    Load file into Autodesk Cleaner 6.5 for compression and watermarking.

    That’s all well and good, but it comes out with a 4:3 quicktime letterboxed for the 2.35:1 material. I want to get rid of those letterbox bars to make the files smaller.

    In quicktime, I know you can go into “Show Movie Properties,” click on video track, and apply a GIF mask to resize the quicktime window. However, this does NOT seem to remove the information from the file… just mask it off.

    For the life of me I can’t figure out a way to permanently delete this information outside the mask area, and every combination of settings I try in Cleaner doesn’t work properly: it either distorts the picture, or throws away the wrong portion of it. Does anyone know how to do this?

    Thanks!!!

    -Matt

    Since you are using cleaner, use the crop feature in there…..you’ll find it. I was going to suggest using a compression app like cleaner, but you are already there!

    In cleaner just make sure that the aspect ratio of your output is set to either same as source/maintain aspect ratio or set explicitly to 2.35:1. This method won’t introduce the letterboxing, as such they’ll be no need to crop.
