Struggling with Vegas: Joining, stretching and color balance problem

[Anakunda]

Hello,

I've already aske in another thread with no response.

What I need: Make a movie from two divided parts, respectively the starting and ending part, which overlap partially.

Here's my questions: is there a tool or function in Vegas that helps piece both parts together as smoothly as possible with help of the overlapping part?
If not, does another editing sw provide it?

2nd problem: I can't figure out how to stretch second part which is 720×480 to fill project workspace which is 720×576. Unfortunatelly the starting part is from another source which has another resolution, so I need the ending part to stretch accordingly to starting part so that both parts will be same size.

3rd problem: If the color balance of second part is more tuned to green, does Vegas provide a function that analyzes it and makes the color correction to other part so that both parts will have the same color tone

4th problem: I still get the rendered output less contrast (generally brighter) than the original. How do I force Vegas to preserve source's image brightness/contrast in output?
Used codec: V4W, x264, CRF 22, tune film, autolevel, no restrictions

If one or more tasks I need does handle other software better please give me to know.

It looks like you want to concatenate a PAL and NTSC version of the same movie.
This means to perform a norm conversion.

Vegas will do this anyway, the project settings will dominate the outcome.
But before going to Vegas (and trust the built-in conversion which will fieldblend),
I would normconvert externally using Avisynth.
Here you got much more of a choice to fit the generation of your source.

And before attempting such conversion
I would try to get behind the generation of your source and go back as far as possible
to be able to join these two parts in their native format.

You ask for software, well, all is in your hands.
Avisynth and Vegas are well up to the task.
Avisynth for source fixing and Vegas for colour corrections, cuts, whatever...
Automated solutions tend to produce what we are dealing with most of the time:
mediocre, somewhere incompatible and eye-drying fast food.

You got to find out.
Virtual dub, MediaInfo, avisynth, separate fields, watching fields, counting patterns.

2: Vegas offers more than one video track. Make up two video tracks and apply Track FX to your liking.
3: Colour: you do it. Histograms, Vectorscopes, Waveform, Luminance scopes are built-in into Vegas.
4: I always render to intermediate (YUV uncompressed). No troubles.
If one tends to change a bit after rendering one still can achieve this in an Avisynth frontend to x264..

P.S.You are concatenating PAL and NTSC.
PAL sources can differ from NTSC.
And NTSC can have two different black values, depending on country of origin. US vs. Japan.
Feel free to adjust this black value using Vegas built-in Colur Curves tool.

boths are in PAL but i've lost the ending part of the part in original part so that I want to take it from another copy which was already resized to AVI.
Can gI give both parts to Vegas and tell join them as smoothly as you can...and resize the ending part to pixels project same in the overlapping part.
Does Vegas have an analyzer that analyzes the overlapping part and joins both segments seamlessly?

[Emulgator]

PAL in 720x480? Such PAL does not exist.
The most important part is : What about the framerate ?
If both are 25fps, fine.
Re-resize in Avisynth before importing into a Vegas PAL project.

If the 720x480 has 29.97fps it is...well, not really PAL.
External Normconversion in Avisynth suggested.

No it doesn't. But it's fairly simple to just line it up manually; you can resize to match before importing (maybe a lossless avi like lagarith or huffyuv), as Emulgator suggests above

yes yes both are 25 fps but the avi is in 720×480 with different AR which gives the same shape.
How do I resize by AviSynth before imprt, never used AviSynth? thanks

AviSource("<Path to your file>.avi")
Lanczos4Resize(720,576)

Or a bit nicer for a 4:3 PAL VHS source with crappy borders, resized to ITU specs (4:3 picture content fills 704 wide)

AviSource("<Path to your file>.avi")
FinalResizer="133VHS-PAL0720"
#______________________Start of PAL-VHS/Video8 - 4:3 Crop and Addborders on 4:3 PAL 720x576__________________________
FinalResizer=="133VHS-PAL0720" ? Lanczos4Resize(704, 568, 16, 4, -16, -4).AddBorders(8, 4, 8, 4, color=$000000) : NOP
#______________________End of PAL-VHS/Video8 - 4:3 Crop and Addborders on 4:3 PAL 720x576___________________________

I did render so (Template: Default template (uncompressed) (*)). The output is still noticeably fader than source. Couldnot Vegas couldnot fade the video by import from MPG? The video looks fade already on Vegas' preview against mpg shown in video player.

[Emulgator]

Do we have .avi or .mpg ? Screenshots please.
The curves tool is ready at your hands in Vegas.

what video player? it's likely using graphic card overlay settings (overlay renderer) . vegas' preview window uses graphics card desktop settings (GDI), hence the usual discrepancy

1. There's White Balance filter in Vegas Pro 9. If you have clean white in vide it can make magic. I'd not recommend it though.
Manual color balance is less error-prone. With track FX help you can make picutre-in-picture or spleet-screen view (temporary, obviously, for the time of editing). Then you can tweak colors as you with on one part so that it looks like another one.
2. Pan/Crop is designed for it. Uncheck "lock aspect ratio" checkbutton and you can stretch video as you with.
Trackmotion should be used with caution here as it leads to multiple transformations (media->track->track affected by track motion).
3. No, Vegas uses quite the opposite logics: you set up tweaks for media/clip/track as you wish. Reference screens and scopes will give you good idea of what you have and want to achieve.

Couldnot Vegas couldnot fade the video by import from MPG?
It is possible esopecially with a zoo of codecs in system. Check levels manually and apply appropriate fix...

[Anakunda]

thanks alot. I'm almost done. The last holdback to finalize my rip is aspect ratio. Orig. video was PAL 4:3 which identifies with Display aspect ratio 16:9
In Vegas, corrected movie properties to AR 1.0926 (PAL DV) 720x576
Vegas project properties AR is 1.0926 (PAL DV) 720x576

In Render as...custom options I chose Pixel AR 1.0926 and check Stretch video to fill output framesize (otherwise the picture didnot fill whole frame).

In rendered AVI I get this media info: Display aspect ratio: 5:4
also visually the video's shape is slightly deformed

The questoin: what aspect ratios should I set in movie properties, project properties and rendering options to render as true PAL DV shape (4:3..)

thanks.
