Green screen on timeline when importing .mov file

Summersond wrote on 9/7/2016, 1:54 PM

Sorry if this has been posted before but there is no search on this site yet.  When dropping .mov file on timeline in Vegas Pro 11, I get green screen with sound.  I used JVC HY-GM170 camera set at 50Mbp/s quicktime (MOV) to record.  It plays in VLC but not in Quicktime or Vegas.  Any ideas on how I can get it to play?  I know I can rerender it to MOV again which works but with lower bitrate (11 Mb/s vs 50Mb/s).  Below is info from MediaInfo to assist.  I am guessing codec is the problem but not sure how to go about fixing.

Do you have QT installed?  Vegas needs it to decode QT files.

Some GPU issues manifest as green colors. Consider turning GPU off.

If you upload a sample of original camera video somewhere and post the link here, I'll take a crack at it on a machine that has Vegas Pro 11.

Summersond wrote on 9/7/2016, 3:23 PM

Donald, I do.  John, I will post a link soon.  THX!

Donald, the file is in a mov wrapper but isn't fully compatible with quicktime.  It could be a prores type of file, and I dont have those choices and was unable to get them online, if indeed that was the problem.

John, GPU is disabled.

Normally Vegas bypasses Quicktime for MOV files which contain AVC video and PCM audio. It decodes them directly with internal decoders.

However, your file is using 4:2:2 chroma subsampling and Vegas may not do the bypass for 422 video and may leave that for Quicktime to handle. I do not think that Quicktime handles 422 AVC video which puts you between a rock and a hard place.

If you remux that file into an MXF file Vegas should be able to use its internal XAVC decoder which does handle 422.

Speaking low level, Vegas has two AVC decoders from Mainconcept internally and only the "broadcast" decoder supports 422. Vegas ties certain decoders to certain file formats. It is just the way the developers decided to organize things. The Broadcast AVC decoder is tied to the MXF file format. The Broadcast decoder supports up to 422 and 10-bit. The "consumer" decoder only supports 8-bit 420 video.

I got the same green screen on two different machines.

Handbrake will open and encode it with loss of quality.

Summersond wrote on 9/7/2016, 4:20 PM

Thanks Norman.  By remuxing to MXF, will I lose resolution going from 50Mb/s to a lesser one?  That is my main concern, as the end product will be only DVD format for the client.  Remuxing to MXF then rerendering to MPEG2 for DVD may have create a hit on the final picture quality, but I may need to do that this time.  I just won't use 4.2.2 selection next time!

NormanPCN wrote on 9/7/2016, 4:57 PM

Remuxing does not change the video or audio. It is simply repacking the video and audio streams into a new file container. Transcoding to something else can cause loss, even if you cannot see it. It all depends on what you transcode to.

You can transcode to an intermediate with no visual loss. DNxHD (in mov) and Cineform (in AVI) are a couple of common options.

As for remuxing to MXF I am not sure tool can do that for you. I would use ffmpeg but the MXF support there is limited to AVC Intra only. Your video is LongGOP. Of course a transcode to XAVC would work similarly to DNxHD and Cineform.

Summersond wrote on 9/7/2016, 6:26 PM

I transcoded the file to .MXF using Sony Catalyst Browse (free) and their transcode feature.  This particular setting did not work. - AVC Long 50Mbps.  I will try others as well.  I will try remuxing to one of the others you listed to see if that works.

Here are my choices in Browse.  There are sub choices under each main format.

@ Summersond, I use a JVC camera too (HM-750) and any time that I record in MOV format, I have to use a free utility that I found on the Convergert Design website to transcode the MOV files to MXF format. Once I do that I can load them into Vegas. Good luck.

Thanks Mike!  I will try that.  Lesson learned - don't use 4.2.2. :)

Summersond wrote on 9/7/2016, 6:41 PM

MIke, I installed the fileconverter program and I get a mount screen.  I mounted it, but don't see where I can add the files per the pdf file.  Suggestions?

rs170a wrote on 9/7/2016, 6:50 PM

Summersond, it's been a long timne since I had to do this but, as I recall, the files needed to be on the original SD card. If you already copied the contents of the card to your hard drive, you needed to copy the entire card's contents and not just the mov files.

Mike

Summersond wrote on 9/7/2016, 6:56 PM

Ok, I still have the files on the SD card and will try that.  Hopefully, it will see the files on there an proceed further than it has now.

NormanPCN wrote on 9/7/2016, 7:32 PM

I did not play close enough attention to your original post. You stated you are using VP11. I do not think VP11 supports XAVC MXF in any flavor.

Also, in your transcode screenshot your setting were for 720p59.94 and your source file MediaInfo report shows a 1080p29.97 file. I'm not sure why the discrepency.

I think you may need to transcode to DNxHD (in mov) or Cineform (in AVI) for VP11. This will preserve the 422 capture of the camera and any transcode losses will be effectively NIL.

 

Summersond wrote on 9/7/2016, 8:09 PM

Oops.  Original file was 29.97, not the 720p59.94.  Must have grabbed a screenshot of the wrong choice I made.   I will see if I can find a converter for DNxHD or Cineform and go that route.  Thanks for all of the help!

NormanPCN wrote on 9/7/2016, 9:01 PM

Cliptoolz convert should be able to do a transcode to DNxHD (mov) with a 422 AVC source. V3 is not free but the trial mode still works with a limitation. You can only transcode two files each time you run the app.
