Thank you, Roger.

I will see if I can figure out that info.

I was kind of 'winging' it as I am a new Vegas user.

Alt enter is project properties.

When you hit render as you can customize the template.

Screenshots of both may give a valuable clue.

The camera that produces the .MTS files is not my preferred capture device because it has audio AGC and no visual display of level, leaving me guessing at settings with an external mic preamp. So I have abandoned that for now. I bought another Android phone for video only which is another can of worms.

I opened an .MP4 file this AM from the phone and found it was recorded upside down...I have seen landscape/portrait correction 'blocked' by accidental unchecking of AutoRotate box. But upside down...'Smartphone'?

I am alarmed to see the audio MediaInfo for the new video is AMR, Narrow band, 12.8 kb/s, 8 000 Hz, 13 bits 1 channel. I did not find any settings in the phone for that. I used Cinema FV-5 to record (fresh install & I had not checked settings but have never seen anything other than 48000 previously). This is not related to the .MTS file problem on 6 May, but is disturbing, regardless.

I corrected the inverted video with two 90 degree rotations and rendering output. I did not realize the audio was 'lofi' until today, using MediaInfo. However, the .MP4 file plays in (Windows) Media Player and VLC, seemingly normally (even if narrow band), but video preview in VPS21 produces only horrible static, before or after editing.

I have only captured 48000 b/s with Google Pixel (2016 and 4a versions). This new phone is a Moto so if it will always capture lofi audio I'll be putting nails through its coffin.

I will try opening a video in VPS21 that I took in March, which was so close to perfect I didn't edit it at all, and see if I am having 'operator errors'.

Looks like my .png screenshot(s) is not a compatible format here, and I don't see a way to delete what is attached.

It deleted itself...nothing to show... have to redo the screenshots as .jpg I guess.😵

Not understanding the video preview results, I attempted opening the offending .MP4 file in Sound Forge 17 and it rejects the .MP4 file with a reason (screen is long gone, so I can't say exactly what).

Attempting opening it in SF15 produces an Apple QuickTime error I have had before & can't resolve because the versions of QT I can find on the 'web all have the same deficiency.

So apparently some of my MP4 files proudly boast to VPS that they require an old version of QT, because others from different cameras open fine. Looks like I'll be renaming the moto phone as mofo moto. Oddly, they were associated with Google a while ago and Google phones (when they work) seem to produce problem-free video & audio.

I think I will go do something more productive for a while.

PNG screenshots do work here, feel free to try again.

@MURRAY-LESHNER Excuse my ignorance but what is "SFAS 17"? A Google search brings up nothing that appears to relate to video.

Magix Sound Forge Audio Studio, which has a very small set of video tools. Its included in Vegas Pro Suite. Prior to acquiring VPS 21, I used SFAS for a few generations. The learning curve for me with Vegas is vertical...like a brick wall. I am not evolving and my knuckles are scraped.

Thanks Murray. I should have guessed. I have actually, years ago, used SFAS!

I had to look it up three times to spell it out...I kept forgetting what the S stood for!

The first two screen shots are the default settings for a new Project in VP 21. The 2rd (largest) is the strange 8000 Hz setting captured by the phone.

Usually AVC video codec is combined with AAC audio codec.

So, by Mediainfo data, you are using Motorola Moto G Power 5G ?

This is out of 'usual MTS format' that I usually have from my AVCHD camera, not standard, so I'm pretty sure the Vegas Pro 21 getting confused on recognizing the media.

Can you switch the video recording format to other setting? Change from MTS to MP4?

Looking at the PDF user guide, page 36... the only settings for VIDEOS is "Efficient Videos: Turn on to reduce the file size of UHD videos. " ?

I cannot recreate the AMR audio encoding with multiple camera/recording apps.

The night that happened, the phone rebooted to Android bootloader level because the phone gimbal clamp pressed multiple side buttons.

.MTS is what my older Sony camera produces for its highest quality AVCHD video. The .MP4 options are lower-res.

For the moto settings, all that UHD option does is select HEVC or whatever the new phone format is. I am avoiding that for photo & video because I keep finding software that doesn't recognize it.

I have created short videos since then with various camera apps that all had 48000 (sample rate?) but the (bit rate?) varies between 120000 and 256000.

moto support suggested trying alternate camera apps because the settings in the phone are mostly hard-coded (only the High Efficiency switch was accessible).

I tried the Android default/native Camera (video) app, Open Camera, Cinema FV-5, Saramonic (external preamp app) video and FeiYu gimbal app video.

Oddly, only the Saramonic app had an option for 4K, but the only Media info details I note different were 60 fps vs.30. I don't know think this phone can do 4k.

FV-5 has a setting to ATTEMPT disabling audio AGC/ALC if phone allows it.

So this seems like it was just a freak encoding 'accident'.

Back to the learning curve.

I should rename this Videos of Sisyphus...condemned to rolling incompatible videos up a mountain for eternity. It's not really about .MTS or lost .MP4-converted audio anymore. It's about wrestling corrupted (unwanted formatting) videos into and out of Vegas now (as a sub-step of learning curve).

The AMR 12.6 kb/s 8000 Hz audio phenomenon returned. I had hastily tried a handful of camera apps with a phone's internal mic, and none of them resulted in the low-fi audio. I did wonder if I really needed to try the external mic & preamp again...nah, tooo much trouble.

Next live video event produced the same low-fi audio with inverted video. Kind of odd the phone auto-rotate setting doesn't recognize 180 degree rotation as a problem, only 90 degree. I decided to 'process' the videos with the audio as-is for the exercise itself. The difference was that I used the Saramonic Smart Rig II XLR input - 3.5 mm TRRS-output preamp I have used with a different phone AND with a mirrorless (Sony) camera via a 3.5 mm TRRS(f)-TRS(m) adapter. By luck, this worked with the Pixel phone and Sony via adapter, but the moto g phone may have a different mic jack wiring or other 'smart' misinterpretation that makes it not 'like' my hardware of choice. I will force myself to see if I can find one phone app that captures 256000/48000 audio as intended (preset in most camera apps), but this may be phone to donate to someone else.

I can open the H264 videos and 'correct' the video inversion with two 90 degree rotations but this time around I discovered there is a difference between Open and Import Media for my .MP4 files.

Import Media (.MP4) has Render 'greyed out' but Real-Time Render is accessible.

Open (.MP4) has both Render and Real-Time Render accessible.

But I forgot where I found the rotate 90 degree operation was in the toolbar menus.

Maybe an analog (paper) notepad to help me lay a breadcrumb trail to find my way to a previous level of 'progress' is necessary.

I'm stubborn, if not intuitive.

The mirrorless camera seems usable, but for the lack of audio level interface (visible settings) and guessing. The preamp has not been able to produce yellow or redline audio in Cinema FV-5, but the (NEX-7) Sony's apparent audio AGC/ALC seems to try to hard resulting in distortion at times.

I'm desperate enough to re-achieve the excellent quality (video and audio) I got with the 2016 Pixel, I ordered a new battery, tools and a spare LCD display) to rescue that phone.

Hey Murray,

• Upload an original  .MTS file, shorter is better, to Google Drive or Dropbox and post the link here.(Aside: We know what .mts files are, having worked with them since their origination as a digital video tape format by sony in 2006).
• We would like to try it on different builds / versions of Vegas and get back to you with some real answers.

As a fellow user, I appreciate your thoughts and speculation, but without hard tests of your original source .MTS video, the rest of your efforts, including possible re-encoding in various versions of Sound Forge and etc......., are not as helpful.

Thanks, and welcome to the discussions. The information we like to receive from new users with questions, is here: https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/
