Reference to Nested Project –
Inserting/Expanded

The answer by PowerDirector Moderator
from New Taipie on Oct 18 2016 and the followup was very helpful explaining it to a
Dummie such as me. They should have you write the Manual.

My query here is whether I am on the
right track in a project I am commencing to reedit old VHS source
material.

Because I will be using the Enhancement
and Stabilising tools extensively, along with the usual titleing and
transitions, it means my rendering times will most likely be quite
slow.

I am intending to break up the project
to 15 minute blocks, probably 4 blocks for each DVD using the nested
feature to bring it back together for completion.

1. Should I render each block as a MPEG-2 file and bring those files back to finish the project, this would make the rendering more manageable or 2.
should I bring back the edited project files and render the lot in
one go.

The first choice means rendering twice,
and I wonder if this would affect the quality.

In a previous test I found the second
choice meant rendering time of 3-4 hours. RobertA101

Every render decreases quality, that is why I capture lossless in another application.
You will actually render THREE times! Your capture is compressed, then your render, then another.
Using VitualDub I capture lossless MagicYUV, in a YUV colorspace and 720x480, then edit once in PD. The result is first generation compression in MPEG2 or MP4.
Capture compressed if you only plan on simple cutting, period. Any edits for color, or cropping (head switching noise, tearing, poor edges), anything other than cutting will result in generational artifacts.
With VHS being so crappy on it's best day, every bit of quality matters.

In my view, if you save in 15-minute blocks on MEG-2 with the quality you want to finalize the DVD.
You will have no losses if you use the same quality or Profile Analyzer "SVRT" that works 100%.
The simplest, nest projects and produce at one go.
Currently I have trimmed the defective edges of the VHS and for me it does not have much loss of quality, and to visualize on Led TV I think better than seeing the defective edges.
But if I apply any improvement even stabilization I think it gets much worse.
I use to capture, Philips DVDR3380 recorder, files (.VOB), quality HQ, SD 1 or 2 hours. XEON-E5-2680 v4 / Mem. 16GB DDR4

Thanks Barry and AV
I must check out Virtual Dub and Magic YUV as I know nothing about them.
I think I will stick with rendering the 4 projects as one.
The next problem I am having is with Multitrim misbehaving
Will make a new post if I can't sort that out
Thanks again RobertA101
