Doesn't render rv24 AVI correctly. Distorted/Cut.

[brockb]

Is there anything I can do to get it to render this AVI correctly in VLC? If you look at the picture below... the top left feed is how it is being displayed in VLC and the bottom feed is how it is supposed to look (which is being fed through Windows Media Player 11 on the same machine.)

It appears as if it is cutting the file in two at a diagonal and then skewing it.

Any ideas? I would love to get it to where VLC can play it exactly like WMP plays it on this machine. We may be S.O.L and have to use WMP right now for the sign until we can find something better but VLC would be our first choice otherwise.

Thanks!

Here is a little 5 second clip if somebody wants to try it out on theirs and see if they are getting the same results. It is rather large even though it is only 5 seconds since it is RAW. LINK

Try it in VLC & WMP and see if there is a difference for you?

My next question (if there is no way to configure through preferences to get the video to render correctly in VLC) might be... is there information somewhere on how to update the codec libraries and compile VLC with a codec that will render the RAW output correctly?

Thanks,

Here is a reporting on the file from MPlayer that does play the file.

unscaled bgr24 -> yuv420p

Badly interleaved AVI file detected - switching to -ni mode...

MPC would not play the file at all. VLC gave me the equivalent of your post. WMP 11 using WMF 11 did NOT play the file at all.

To me this looks more like an encoding issue than a player issue for a format that seems to be disappearing.

Hmmm... I've run it through Premiere Pro using:
Microsoft Uncompressed AVI: Compressor = (10-bit YUV 4:2:2: YUV)
Microsoft AVI: Compressor = UYVY 422
Microsoft AVI: Compressor = none
Quicktime: Compressor = none

And none of those will play in VLC... they all end up with the split/skewed and colorless.

Even H.264 compression shows signs of compression so our customers require RAW/uncompressed video. I can't get VLC to play any uncompressed/RAW videos. Do you have any RAW videos or know of any that VLC can play? If so I'd like to download them and give them a try. It will at least help to rule out definitely whether or not VLC can play RAW. If we can rule that out then we can start looking at how to compile it with RAW support or stop pi$$ing in the wind and look in another direction for a player. I hope we can stick with VLC. *** fingers crossed ***

Supported Formats

I believe these are all of the Chroma formats:

I420
I411
I422
YUYV
UYVY
RV24
RV32
I42N
I41N
GRAW

RV24 and RV32 seem to be common for raw video.
But I believe all of these are considered Raw video or perhaps no format.

No or low compressed MPEG 2 in the form or a HD .m2v seems to be acceptable to most professionals. Also an HD h.264 that is not highly compressed also seems acceptable though editing is a issue with this form. VLC is one of the few players that will play .264 and or .m2v files. Both of these formats are considered raw video only in the sense that they have no container and the amount of compression can be varied from non to what ever you deem acceptable.

Thanks for the help DJ.

I can't see where Adobe Premier Pro will allow you to do Mpeg2. It will allow you to do an AVI container with MPEG4 compression (and it has v1, v2 & v3 codecs to choose from).

I just tried exporting .mov with H.264 compression at 100% quality with no recompress and it does a pretty good job but it is still quite noticeable. Check the screenshot where the H.264 run through VLC is in the upper right and the regular raw run through WMP is in the center.

The colors seemed a little washed out and the compression causes some artifacting in the gradient and you can see the colors bleed together with the (yellow and blue) and (red and blue) bars.



Maybe I shouldn't be trying this with Premier Pro. Any suggestions on another program that can convert raw to H.264 or .m2v with a greater quality?

Thanks again,

Yes! I have noticed this and I'm doing an enhancement for color and a slight sharpening for the edges when transcoding into h.264

Have you tried M2V for MPEG 2? This is the easier form if you want to make changes later with an editor and not transcode the whole thing again to loose a generation.

Well the good news is... it isn't VLC that is causing the dull colors and artifacts... it looks the same way in QT. It is just the way Premier compresses it during export. QT has the same dull colors when running the file. It looks like the lines might be just slightly sharper so I don't know if QT runs a sharpening agent automatically or not.

I'll look around and see what I can find for going from AVI/RAW to MPEG2/M2V and post my results here in the next few days.

Thanks again.
