Windows 10, Vegas 18 (although I've seen this in earlier versions too) M2TS import contains video but no audio. I know the audio is "there." VLC sees it. AUDACITY sees it. Using FORMAT FACTORY, I can convert the M2TS to MP4 and Vegas will then see both video and audio in the MP4. What am I doing wrong?
What am I doing wrong?
Nothing yet, other than not posting your required file properties.
Obviously I don't understand. I don't have any "required properties" other than I require Vegas to put both the video AND the audio of this file onto my timeline! I followed your "faq-how-to-post" link and have include mediainfo and vegas info below. I shall appreciate the opportunity to gain some education. Thank you in advance.

I'm not at all sure what the problem is, but converting to mp4 in Handbrake should also solve it.
I would guess that Vegas doesn't expect to find AAC audio in an M2TS wrapper.
"Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity"
If you can losslessly convert to an MP4 wrapper, that would probably work.
M2TS typically contains AC3 and/or LPCM.
I just figured it out per j_d. Vegas does not accept MPEG-2 video with AAC audio, the extension notwithstanding.
Solution is the same as suggested. Post back if you have video drops from your broadcast transport stream.
Looks like this m2ts is not a standard AVCHD or HDV format.
I even check my AVCHD media:
Audio ID : 4352 (0x1100) Menu ID : 1 (0x1) Format : AC-3 Format/Info : Audio Coding 3 Commercial name : Dolby Digital Codec ID : 129 Duration : 1 h 1 min Bit rate mode : Constant Bit rate : 256 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 31.250 FPS (1536 SPF) Compression mode : Lossy Stream size : 113 MiB (2%) Service kind : Complete Main
HDV media:
Audio ID : 2068 (0x814) Menu ID : 100 (0x64) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Codec ID : 3 Duration : 21 s 840 ms Bit rate mode : Constant Bit rate : 384 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Frame rate : 41.667 FPS (1152 SPF) Compression mode : Lossy Delay relative to video : -80 ms Stream size : 1 024 KiB (1%)
so, yes... above replies' confirm.
Instead of converting the whole video, you can also just extract the audio to, say, WAV format as well.
That's correct. It is from an OTA recorder, and they come in a variety of flavors. MTS and M2TS can wrap either AVC or MPEG-2 video streams, but HDV / AAC, and AVC / AC3 are both nonstandard. Mine does MPEG-2 / AC3 5.1, "similar" to XDCAM-EX 1080i ATSC at 12Mbps, and with super nice quality. And VideoRedo knocks out the commercials, and saves 1080p x264.
