Thanks musicvid...

I hope my pictures show up as I am a bit unsure how to post them...

DNxHD is version v2.3.7

Handbrake is 0.9.8 (2012071700) - however before I get to handbrake the render VMSP11 the colours are all wrong. If I put the wrong coloured MOV into Handbrake it come out with the same wrong colours.

I do not use intermediate format, my HDV footage was captured using VMSP11 and I use the captured files directly (they are m2t) in the timeline when editting.

Below is media info on my video captured by VMSP11 from my HV20:

This picture is how it looks in the VMSP11 preview window:

This is a picture of my render settings:

And here is the output after it is rendered by VMSP11 (playing in Quicktime):

That is odd indeed. Cool effect though ;?)
Please upload a 30 sec sample of your original camera HDV footage somewhere somewhere so I can try it on my system. Dropbox is good.

Couple of things:
Are there some effects or filters on the timeline?
On your DNxHD settings, Alpha should be None and Audio should be PCM, not QDesign.
Does the playback look the same in VLC Player?

Thanks musicvid,

How do I just do 30 sec sample from my original HDV? I do not have the tape anymore to just capture 30 seconds, so I would have to cut a section from what i have captured on VMSP and cut a 30 second section for you and rerender? If I try that then it changes to an M2V rerender it.

I will see if I can upload it, unfortunately here in Africa we have terrible internet connections, so I will see what I can do.

To answer your questions:

- no filters on the event or the video track.
- although the notes say qdesign, if you look at the format (in the custom setting window in the one picture I provided) it says 48kHz 16bit stereo PCM. I selected in the audio tab Uncompressed 48KHz 16bit stereo.
- no difference if I set the alpha to to none.

NOTE - In VLC player it looks fine, colour is normal!! mmmm...

1. You can shoot 30-60 sec on your camcorder, capture the file, and upload it somewhere.
2. You can smart-render 30-60 sec. from a larger captured file in Vegas, which means No Recompression. Then you can upload it somewhere. Search the forums if you do no know how to smart-render HDV in Vegas.

"NOTE - In VLC player it looks fine, colour is normal!! mmmm... "
Then don't use Quicktime Player for Windows. It is by far the worst possible choice.
Does the same file rendered to x264 in Handbrake play normally in VLC? If so, mission accomplished.

Thanks musicvid,

I will try rendering the file in handbrake and view in VLC, if it looks fine then it would seem that quicktime is screwing the colours up, then as you say - mission accomplished.

Why would quicktime screw the colours up though?

I can't even open open dnxhd in qt, but my guess is it is misinterpreting YUV colorspace as RGB.

qtfw doesn't get a lot of things right, about as useful as t*ts on a boar hog.

Greetings,
I've been growing fond of this free media player called "Daum Potplayer."
It provides the widest screen view with a thin border that I have seen.
Below is part of a CNet review about it.

"Daum Potplayer: It's probably not what you're thinking, whatever that is. It is, in fact, a free video player. We hear you say, "There are so many free video players; what sets this one apart?" Its built-in codecs handle most video formats, and you don't have to install them yourself. It has several levels of controls and settings, making the most useful commands easily accessible. It's attractive but also skinnable and customizable. It supports a variety of video devices, including capture devices like cameras, DVD and digital recorders, and both analog and digital TV, including channels."

"Potplayer opened with its Playlist window displayed, but we could toggle it open and closed from the interface. This player has a full suite of familiar controls and counters on its interface, including full screen, repeat, shuffle, and volume, but you can also access filter and rendering settings, speaker options, and other settings from the main window. Right-clicking the interface or the program's system tray icon accesses an extensive main menu..."

Thanks,

I take my DNxHD renddered file and handbrake it, look at the handbrake video in VLC and all looks fine. So everything seems to be OK then, QT was obviously confusing me with it's wrong colours.

One more question though: If I am trying to keep the rendered file sizes down to as small as possible, why do I have to make the audio umcompressed PCM? Is there not another setting I can use so that my rendered file is smaller (I am assuming that PCM uncompressed audio will be bigger than a compressed format for my audio)?

Again thanks for the help.

PCM is the only portable format that retains full quality for the DNxHD intermediate.

As per the tutorial, AAC is the most universal audio delivery format from Handbrake. We have to live with its limitations (AC3 is not supported by Flash and many devices).

Passing PCM audio out of Handbrake is ridiculous. So is giving Handbrake garbage audio to work with.

Why use HDV->DNxHD->Handbrake instead of HDV->HDV->Handbrake? Then smart render is supported, and the only re-compression is during transitions/overlays, etc.
