Please correct my errors and suggest best way...

I have recorded a show with 3 cameras:

Panasonic GH-2 : 1920x1080 25 fps interlaced top field first
Panasonic TM900: 1920x1080 50 fps progressive
mpeg2 camcorder: 720x 576 25 fps interlaced top field first


I setup the project to "1080-50i (1920x1080; 25,000 fps)" top field first and started adding files to the timeline without paying attention to other settings.


I was asked to urgently produce a dvd with a rough cut, so (probably doing wrong) I changed project properties to "PAL DV Widescreen (720x576; 25,000 fps)" lower field first. I immediately realized that gh-2 videos had interlacing problems on moving borders/objects, visible in the preview. More then the typical interlace/progressive problem, it seems to be the field order problem. To solve the problem I had to set "Reduce Interlace flicker" but I feel it is not good in this case, since it seems that it interpolates the fields. But I found no other way.


When dvd rendering was completed I switched the project back at full-hd 50i and then realized that the mpeg2 camcorder events had the problem too.... the video is upscaled, of course, and it is visible the typical interlace/progressive problem. I also solved it setting "Reduce Interlace flicker" also if I think that the preview showed the problem and on tv it won't be shown...

How many errors I did ????

Finally, I'd like to ask you what settings should I set on Vegas Pro 12 project and on source video files to have an "easy" way to produce sd DVD (interlaced), and HD (1080 or 720) progressive or interlaced to view from media player/set top box.

Thanks
Francesco

Did you select a De-interlace Method in your Project Properties?

Anything except None would do, Interpolate is generally the best choice.

Thanks Bob,
I felt I was missing some basic setting.....

Should I set "Deinterlace Method:" to interpolate on every project with different mixed source types ?

The deinterlace method matters if you are rendering to a de interlaced output format. In this case it sounds like you are going to render to an interlaced DVD format (recommended). In that case it is important to specify a deinterlace method but it doesn't matter which one (blend fields or interpolate). What Vegas is going to do transparently in the background is to separate the even and odd frames, resize them separately, then fold the two fields back together by alternating lines at the output frame size, thus preserving the temporal motion. If you were to select "none" as your deinterlace method, Vegas would do a simple resize and there would be aliasing of the interlace comb edges which would look like wavy lines at the edges.

I leave it set to Interpolate for [I]every[/I] project.
I don't know of any scenario when one needs to use anything else.

It's a matter of taste I suppose. In the past I have preferred blend fields for fast movement that judders.

To be honest though, I haven't done anything but a decomb deinterlace now in several years. I use the deinterlace method in Vegas ONLY for resizing interlaced video from one size to another, and come to think it, I rarely work with interlaced footage these days.

Another way you could do it would be to make intermediates for the non-GH2 footage using Handbrake. This would have the advantage of doing a resolution preserving decomb instead of deinterlace, and the uprez would be a superior looking lancos 3 as well. I would probably go this route these days if I was headed for HD output.

Ok, let's say that I'm an hobbist, and I edit primarily sport and shows where my relatives are involved. This is the reason I don't do too much editing and every time I recreate my workflow.

2 years ago I taped a show with 3 cams (2 SD and 1 HD) so the project was set to DVD and to match the look of the cameras I added noise to the HD track.

Due to a strange combination, I now own a gh-1, a gh-2 and a tm900 and I'd like to have the editing and final rendering in HD. I now also have a bluray burner so that I can deliver them if requested, or I can give videofiles for media player playback.
Unfortunately I will have to deliver copies to dvd and I'm looking for a consistent workflow.
In the past I added sharpening set to 0 on the video bus track and rendered as PAL DVD from inside vegas. Since I don't get any money from these dvd, this is good enough.

Instead, on the HD side, I'd like to achieve the best quality. I have no problems in creating proxies, intermediates or any other type of converted files (decomb in handbrake), but I need to understand what conversion to do in which cases... can you help please ?

thanks

Probably you wanted to say non-TM900 (progressive) instead of non-GH2
Laurence wrote on 5/6/2013, 5:37 PM
Actually, the GH2 footage is progressive as well. It's progressive wrapped in an interlaced wrapper. I'm so used to ignoring this that I forget sometimes that it is not obvious.

Really, the only footage that doesn't match up is the mpeg2 PAL SD stuff.

In full hd:
GH-1 is progressive (25p in 50i)
GH-2 is progressive (25p in 50i)

tm900 is only full hd but can be 50p or 50i. I just can't find if its 50i is a "real" 50i or 25p in 50i....
