I have some original video footage that is in mp4 format. Most of it I want to cut out. For the sake of discussion, say of video 55 min is fluff (can be cut) and 5 min is what I want to keep. I'm using Sony VegasPro v10 x64 on Win7 if that matters.
If I see that the video is mp4 format 640x480 as an example, but might be other formats. My current approach is to do the following:
(1) Set the properties of the vegas file to match the source, so if the source is 900x600, then I change the properties of the vegas project to match that. If it is 640x480 then change the vegas file to match that.
(2) When rendering, use custom rendering. I currently am using MainConcept (*.mp4) with Default Template and then select custom size to match the source. So the render format is identical the the source format both in file type, and in size.
My goal/attempt is to somehow cut out parts of the video I no longer want to reduce the file size when archiving the video.
My question is this:
If I do the above steps, will I have good results at not loosing source image quality?
The reason I ask, is that I want to do further editing on the "trimmed video" so I want to know if I need to keep the original video around or if I can delete it after I have re-rendered and trimmed a 40 min video to 5 mins.
NOTE: Vegas has another feature that might be better suited. I forget how to use it now, but it allowed me to say copy all of the original footage to another project but only what I was referring to (adding some number of frames to the start and end of each video clip). This is the feature I think would be better suited for what I'm trying to do. So if you know this answer please share it.
