  Can’t open a specific video file?

  Posted by Daniel Mangoianu on July 3, 2017 at 12:26 am

  I’ve been trying for a while to open a video file in Sony Vegas, as it gives me a message saying either it has been corrupted or is an unknown file type.

  Here are the specifications:

  format: mp4

  video encoder: libx264 (h264 i’m guessing)
  pixel format: yuv420p
  – 40 mbps

  audio encoder: ac3
  sample format: fltp
  sample rate: 48k
  bitrate: 320 kbps

  I am able to change these settings when recording, but i’m not sure what video encoder works with which audio encoder, container, etc.

  Can anyone help?

  Good. This has confirmed the audio is AC3. Vegas has a history of difficulty with importing AC3, there are some exceptions and workflow workarounds to this, but mostly it’s not a good idea to involve AC3 anywhere in the import workflow. You can go ahead and research the options in getting AC3 into VP. My thoughts would be to irradicate any AC3 Capture.

  Also do check the part of the MediaInfo reporting logs that reveal the available CODEC on your PC. This will further indicate if your PC will deal with both the Video and Audio content.

  I hope some of this helps.

  Would there be a way to convert the AC3 to lossless format without re-recording the entire thing? Any free programs that would do so?

  [Daniel Mangoianu] “Would there be a way to convert the AC3 to lossless format without re-recording the entire thing?”

  On a tangential approach I’ve imported my own DVDs back into Vegas Pro. These where DVDs I’d created/burnt using DVDA. Now, realise that these would have been videos compressed down to a lower res MPEG. So how lossless you’d want, I dunno!

  Any free programs or any programs I’d point you to? I haven’t used nor needed to – sorry ???? …. My workflows are straightforward and have been honed down by bad hard-knock purchases I’ve made over the decades, resulting in a wish to keep my Capture to Import to Edit to Deliver as seamless and as simple as I can, leaving me free to do the fun thing, being creative! ????

  Seriously, there should be something out there, but finding it or modding it for your needs is beyond my abilities.
