How to downgrade Canon 5DII video to 480p?
Hi All,
I would appreciated if someone could give me some advice on how to downgrade a 1080p video to 480p/16×9. My audience for my current project doesn’t have blue-ray players, so I need to downgrade my videos.
1. One of the problems I noticed is that Vegas 10 Pro, for some reason thinks my Canon 5DII files are interlaced video, when I select them from explorer.
2. When I drop my files on the timeline in a 480p widescreen NTSC template, and render out to mpg file, the video flickers on the screen, and the aspect doesn’t look right. The video quality even looks like its 380p or something because I can even see the square pixels on the TV/LCD screen during playback.
3. How do I tell Vegas to change the color space to YUV?
4. If I just use Virtual Dub to re-size the 1080p video, using the lanczos3 filter, then encode the avi, the video looks great, but I want to use Vegas so I can add lower thirds, but the video just looks terrible when I render from Vegas.
These are my source files.

Hmm, odd. I downloaded them and my copy of Vegas recognises them as progressive.
If you render in MPEG 2 ‘DVD Architect NTSC Widescreen video stream’ it looks great, and it says ‘YUV, 6 Mbps’ answering your third question.
It looks just as good as any television or DVD I’ve seen, because you usually watch television from a few metres away where on computers you’re sometimes only inches away!There does seem to be a bit of aliasing, however, but this seems to become less noticeable when you add some Chroma Blur.
Perhaps you should try rendering with the setting I mentioned, and stand far away from the screen when you view it – like the distance you would be if you were watching television – and it looks wonderful!
I don’t understand why you’re having such a dilemma though, it seems fine here. Perhaps someone else will be able to offer better help!
Nice car, also.

Thanks for looking into this for me. After your suggestion, I figured out what I was doing wrong!
The file got converted to interlaced in my workflow, which I believe caused the flicker, and pixelation I was seeing on the screen. I can’t believe I wasted all this time, and it was a workflow issue.
Just out curiosity, what should should the pixel aspect ratio be set to on the project and video/time line level 1.00 square or 1.22 widescreen?
Thanks.

Same here. My Vegas Pro 10c 64-bit correctly sees them as progressive.
I would edit the whole thing in HD and then render to NTSC DVD 24p Widescreen for your customers without Blu-ray. Don’t compromise your whole project for a delivery format. Just render to whatever formats you need in the end.

That’s interesting! My film I’m working on just now I tend to edit at DVD resolution and render in HD, but only because my computer can’t ‘Dynamic RAM Preview’ HD as quickly as SD. I do use HD for colour correcting etc, however!

If you did want to edit in DVD NTSC 720×480 resolution, go with 1.2121 as this will give you widescreen.
But, like John said, you may prefer to just edit in HD.
Glad you got that sorted!

I just figured out the flicker I’m seeing on some video clips, than others. The ones where I see the flicking is when I have the camera HAND HELD! The other video clips looks Sharp and clean when it’s on a tripod. I noticed the difference when watching the tripod video clip, when I slightly moved the position of the camera on my cheap tripod, it’s when I saw the flickering for just a moment. I now have to invest in a DSLR tripod to help improve my panning, or a hand held rig or something.
