Which intermediate video format best to choose for further processing
I have a 1 hour video material and need to make a 5 minutes clip movie from it, with titles, original soudtrack plus music etc. Because working with this long video is difficult (Vegas is making audio proxy every 5 min or so) and overall it feels heavy in the Preview panel I’d like to divide the project in 2 parts.
First, compose only the 5 min video with original soundtrack and render. Then, make a final movie importing the rendered video and adding music, titles etc.
My questions are:
1. Is it a good idea?
2. What intermediate format to choose to maintain the video quality and make it Vegas friendly (so that it doesn’t constantly recreate the proxy) and overall works well with Vegas as a source. -

What is the source format of your videos? Vegas only makes audio proxies for WMV files and you’re right, you shouldn’t be editing WMV files if that’s what you are using.
CineForm, Sony MXF HD422 50Mbs, Avid DNxHD are all good intermediary formats to use.

My original video format is AVI and it has 3.5 GB and it’s captured from old Samsung camera using standard Windows Vista capture program. Maybe Vegas just doesn’t like the audio. I’ll render in CineForm then 🙂
Btw, the proxy is built also when no changes are made to the project, just switching active window back to Vegas (no sooner than after 4-5 min) initiates the process . -
This is a common misconception but AVI is actually not a video format… it’s just a container file format. The video inside can use any number of formats that use different ‘codecs’. You can use a program like MediaInfo to see what format the video is inside of the AVI file in case you’re interested. The audio should be PCM (uncompressed) but I’m betting it’s not if Vegas is making a proxy.
