What are the differences between FFmpeg 32-bit vs FFmpeg 64-bit on Windows 10 Professional 1909 64-bit?
I am having an Audio/U-PHORIA Meltdown!

I recently upgraded my version of the Mac OS. Today, I found Audacity needed to be upgraded to a 64-bit version. I did so, then found my microphone did not work.

I see that Audacity recognizes my behringer U-PHORIA UMC202HD

Audacity 1
I check System Preferences and verified the mic works with this test...

System Preferences
So, what could be wrong with Audacity? When I click Record, no sound shows up even though I speak into the microphone...

I'm looking for a freeware that could record the sounds that came out from
various apps : can be youtube, zoom,  browser playing a website, a VLC player:
only the sound without the video/screen.

Best if the audio can be saved into various common formats.

Ideally the software is portable (ie just run without installation) but this
feature is optional.

sometimes a few apps are playing concurrently (eg: a few youtube
videos are playing): is there any way to audio-record only for a particular
youtube (the tab that I could select to record) or it'll just record the
jumbled sounds?  Purpose is to record a specific video's sound while
I'm playing another one

My friend asked me to create a YouTube channel so she can post & share "how-to" stuff.  I have created a YouTube channel before and the person just start using it.  This friend wants to have the channel created, post her stuff and have like a bulk of videos, see it if they ok and it looks to her delight in YouTube, then when she's good and ready, let others see her channel.  So how can  I setup the newly created channel not to display or permit her videos to be seen until she want to?
View video frame-by-frame

I do not have an active Adobe Premier license

What tools enable me to step through a video at a frame level? I have a video of myself and want to find a single picture to use in a brochure. So, I know Adobe Premier does this. What free tools also can do this?

I have a file containing 50 or 60 mp3 tracks. I need to manually add a new field in the MP3Tag working screen when the file is loaded, so that I can physically enter a specific number....but I can't seem to use MP3Tag's usually easy to use controls to create a column, name it, and do the work.

What am I missing?

I  am trying to the get VLC apps to run from command prompt (or with arguments) and open a specific audio file, in a specific time -  how can I do this?

I have the above HDMI HD video recorder which just broke (the power is intermittent):
a typical 1 hr 50 mins movie from my Set-Top box will record into about 7.5-8GB of
mp4 videos.

As the above broke & the cost has increased, I got the cheaper recorder below instead:
For exactly the same movie of same duration, the recorded videos take 15-16GB of

Thought both of them are HD (1080p), so what's the difference?  In terms of
fps (frames per sec) or just simply the latter's video compression is poor?

Is there any way or free tool to compress the mp4 without loss of the video
quality including the fps??  

I've come across a tool (can't recall) that could convert/compress jpg images
but not for mp4 or webm or mkv videos
Is there a wireless or bluetooth microphone that I could clip to my clothing and it connects to a laptop with a receiver that I could use for a video presentation coming up?  I use gotomeeting?
AWS, Speech Recognition and AWS

I have heard AWS has an excellent Speech Recognition web API, and wonder if anyone knows of a complete speech recognition app which uses this AWS API?

Apparently, the demo emails you the translation and I hear the translation is great.

Anybody got any leans on an app that can handle speech to text?

I have an old DVD that I love dearly and I want to upload to my cloud and see it any time.  However, when I was about to upload, I thought it was just mp4  files of but it's not.   The DVD is compose of two folders "JACKET_P" and "VIDEO_TS" where the last holds about 4 or 4 GB of data (mostly VOB files) also had 3 files in the root folder of AUTORUN.INF, dvd-rom.exe and go.exe.  I could contact the guys that did this recording but my colleague tells me that that is the format since it has menus and other stuff.

I just want to save my DVD, if possible with the same menu options, in my cloud account and be able to see it anytime and from my computer, iPhone and iPad.  Anyways, I have received a whole bunch of advice that just don't make sense, so help please.

How do you open an audio file (mp3, wav, etc.) and get the length of the file in seconds using WMPLib.WindowsMediaPlayer with Visual Basic 2015?
My recorder is not working when I’m conference in GotoMeeting, Zoom, Skype, etc.  I have checked the sound configuration and there is a recording tab and the device is enabled and says working fine.  How can I troubleshoot to assure that my microphone is working fine for my next conference?
Today I used Facebook Live with Wirecast's presets of 4 Mbps and 30 fps. In an hour I had over 65000 drops frames. My camera is set to 29.97 which I guess explains some of the dropped frames, but when I viewed my completed video it was only 36 minutes and the audio was at least 3 minutes behind the video. Is this because I don't have enough bandwidth or is there another problem with my computer? I never noticed my processor nor memory maxxing out.
Can you recommend good software for a green screen that is free?
Deleting videos from YouTube?

Is there a way to delete videos from YouTube?

And is there a way to delete a YouTube channel?

If so, how?

Are there paid apps/services for the Apple TV that will allow live sports?

Audacity: How to mute all silent periods?

I have pauses between my speech, but sometimes I hear breathing and other small sounds which forces me to edit each one. Or, even a jet overhead which could not be heard as I spoke.

Is there a way to fix all these silent periods at once? Is there a feature (like Amplify) where I could reduce them all by about 10 Db?
