VS X2 outputs corrupted HDV files

[Andris]

When I render a project selecting an “HDV” setting, the result is corrupted. Only about 40% of the image height is displayed. The bottom 10% of the image is inverted to the top, followed by the next 30%, and the balance (the top of the image) is absent. (Audio is normal.) No difference whether I play these files on the PC or on a PS3.

I am using VideoStudio Pro X2. My source files are video only. I do not use transitions or titles.

I capture the video files with a Canon Vixia HF200. They are MTS files, ranging in size from 10MB to 300MB each. I download them to a Dell Dimension 4600 using a USB 2.0 port.

I create smart proxy files and I am able to edit them normally.

Project properties:
· Duration = 5 to 10 mins
· NTSC drop frame (29.97 fps)
· MPEG files
· 24 bits, 720 x 480, 29.97 fps
· Lower Field First
· (DVD-NTSC), 16:9
· Video data rate: Variable (Max. 8000 kbps)
· LPCM Audio, 48000 Hz, Stereo

I am able to burn them to a DVD normally. Until sometime in March 2010, I also was able to create HD video files normally. Those old projects had the same properties as above. Those old files still play normally. But if I create a new HD video file now, it is corrupted.

Output format = “create video file,” and “HDV 720 – 30p”

Output Properties:
· MPEG files
· 24 bits, 1280 x 720, 29.97 fps
· Frame-based
· (MPEG-2) (Transport stream), 16:9
· Video data rate: 18300 kbps
· Audio data rate: 384 kbps
· MPEG audio layer 2, 48 KHz, Stereo

Error Codes = none

This problem affects all “HDV” and “Blu-ray” output formats. Other output formats are OK. The files burn to DVD OK. (I have not tried burning a AVCHD disk lately.)

I downloaded and installed the latest version of DirectX using the link in one of the “Announcements” at the top of this board. This did not solve the problem. (In fact, now if I render a file using HDV 720-30p it does not show at all, and no audio.)

I downloaded and installed the patch for VS Pro X2. This did not solve the problem.

Welcome to the forums,

First I'm not into HD video yet, and I don't use Smart Proxy, however I noticed that your Smart Proxy files are using Lower Field First and then your final project is Frame Based. The one thing that is crucial in video editing, and that is to maintain the correct field order throughout. Some of the other settings are only important if you're using Smart Render. Try changing the field order for your Smart Proxy files to match that of your source clips. If they are Frame Based use it, or if they are Upper Field First use that setting. I suspect that you're source clips use either Frame based or Upper Field First. Lower Field First is used mainly with DV (avi) video files only.

Hi Andris

Can you tell us what type of video files you are using?
Right click a clip and select Properties, What are they?

If you were able to create good video in the past Quote—“I also was able to create HD video files normally” — Then what’s changed with your computer setup.?????

You Say “The bottom 10% of the image is inverted to the top, followed by the next 30%, and the balance (the top of the image) is absent.”
I’m not sure I fully understand your comments here, can you explain further, or maybe provide an image.?????????

Ron,

My source files are "upper field first." I changed project properties for my smart proxy files to the same. That did not solve the problem.

But your suggestion made me look at "mpeg optimizer" as an alternative, and that does seem to solve the problem. Thanks!
