WTV to
I have some recording on my computer DVR that I’d like to edit in Vegas and put on a DVD. It appears these files are recorded in WTV format.
According to wiki, WTV uses H.264 1-pass CBR Baseline profile up to 1.5 Mbit/s, 640x480pixels at 30 frame/s for video, and low complexity AAC stereo at 44.1 or 48 kHz sample rate and 96, 128, 160 or 192 kbit/s bit rate for the audio. (I assume this is correct!)
These files will not drag onto the Vegas timeline. I can use AVS Video Converter to convert them to something that will work with Vegas, albeit this will probably degrade the quality somewhat.
I can convert straight to MPEG, or I can choose AVI, MP4, WMV, or FLV.
1.I convert straight to MPEG and then open on Vegas. However, this footage needs some additional editing. Will Vegas re-render the MPEG if I do this editing, and then render to MPEG again (for DVD) in Vegas?
2. If this is a bad idea, which of the above file types would be the best quality (and open in Vegas) if I converted the original WTV in AVS. (Bearing in mind, I will need to convert to MPEG eventually…) It appears they are all variants of h.264, or I can used uncompressed.
I suppose the question boils down to whether an extra step between WTV and MPEG would degrade the video too much, versus any ill effects (if any) of editing/re-rendering MPEG files directly…

Since this is an SD capture I would render to Motion-JPEG or DV. These will show very little degradation (if at all) and will hold up well when editing. Then do your final render to MPEG2.
If your edits only include cuts and no FX, you could render directly to MPEG2 and then Vegas will “smart render” those sections that are unchanged, but smart rendering only works if your render format exactly matches the source MPEG2 file. You might want to try it and see if you can get it to work. Of course, if you plan on adding titles, or FX, or cropping, or processing in any way, then rendering to M-JPEG or DV is the better workflow.
