Hello, I am looking for some type of software that would be able to help me sort video files I have saved on my computer. Most of the video files were ones that I saved from youtube or from my digital camera, but I have literally thousands of movie files that I have accumulated over the past few years. I want to delete probably 75% of the movie files, but I have to go through them one by one.

For example I have to double click a single video file, wait for VLC player to load, then after a few seconds the video plays. I use the mouse to quickly fast forward and scan through the video to determine if it is a keeper or not. If it’s a keeper I have to close out VLC player and drag and drop the file into a “videos to save” folder. If I determine I no longer need it I have to close out VLC player and send that media file to the recycle bin.

I have to do that task over and over for each video and I have about 7000 total files. Also VLC media player has to be closed out each time I  move or delete a video file, because if the file as active it will not let you change the destination of the file.  

It would go much faster if I could load the files into VLC play list, and after I scan through the video to determine if I want to save it or not, if a program let me give that video a rating such as  5 stars (meaning it’s a keep file) or rate it one star (meaning that one can be deleted). Then once I rate it I could just hit the “load next file” button for VLC player and I can …

What is the best/simplest way to create a customized tracklist to display when playing a CD?

My mother is a (young) 83 year-old who spends quite a bit of time driving in her car each week. She really enjoys listening to recorded talks but has exhausted her supply and is tech-UN-savvy. She's quite comfortable using the CD player in her car however, so I told her I would be happy to create some CDs containing talks from the public domain.

The talks download as MP3 files and we agreed that the simplest navigation scheme for her would be to have the tracklist display as follows:

    |    Track #    |    Speaker Name    |    Date    |    Venue    |    Title    |

I haven't created many CDs in that manner but it seems like downloaded files (or maybe all MP3 files) usually contain data which appears by default in the tracklist. If that is correct, and:

if I've got the data I want to use in five corresponding columns in an Excel spreadsheet, what is the best method or software for:
    1) overwriting the default data and
    2) creating a tracklist from my spreadsheet?

By the way, I've got VLC Media Player installed. Is that a good option?


I have created a media upload website.
Anyway, I'm concerned that my dear users might upload songs or videos, only to have them stolen by renegades and losers
I applied for trademark of my website name today on legalzoom.
I once heard that having a provable version of art, eg, a recording/book in a mailing, is as good as copyright.
Can I have a text field for my artist 'Megatrons' to say for their song 'home invasion'
" Copyright @2017 Megatrons"
and that have meaning, legally?
What should I consider?
We use a Sony Handycam camcorder to record amateur sports team matches.

We have been using the software that has come with this camcorder called PlayMemories Home to merge these videos together.

This was done on a Windows 10 PC.

The problem is that we have experienced a lot of problems trying to merge videos together using the PlayMemories Home software.

This software does not seem to work with merging videos if the formats of videos are different.

What would you recommend as a better product than the Sony PlayMemories Home software for merging videos.

I have a Sony Handycam HDR CX240 camcorder.

This camera will be used to record video outside for a few hours.

A good few people would like to watch this video footage live while it is being recorded.

Facebook Live seems to be a good streaming service for this task.

How would I stream this video footage through Facebook Live through use of my Sony Handycam HDR CX240 camcorder?

I plan to get the 30-day free trial for Adobe Premiere and wonder if Adobe Premiere would replace Audacity (for me) for audio editing?

I have use Audacity for years to make my own recordings and am pretty handy with it. But if Adobe Premiere is good enough, I may have no need for Audacity.


To test my astonishing new web site, I need some links to a few music videos mpg's or mp4's, both file types will help. Any will do, even Kevin Federline. They are hard to find.
I'd prefer direct links, not needing to sign up for anything.

Also, the freelancer helping me has only catered for mp3 and mp4 uploads.

How can I tell him, this is not enough, do wav and AVI also along w mp3? Is that correct - do amateurs use mp4 and AVI? I used wav and mpg, I assume it is most needed?

Hello everyone,
We have a ShoreTel VoIP system at out site and we use the Softphone in our board room to make calls, have small teleconference calls and calls into Spiderphone for larger teleconference meetings.
We ran into an issue during a teleconference meeting using ShoreTel Softphone to dial Spiderphone for a larger group.  When a video file was played on the same computer as the ShoreTel Softphone the participants on the other end of the teleconference could not hear the audio from the video being played.
Is there a way to fix this or do I need to just start using GoToMeeting?
I don't think there is any such software since I've been searching for days but I thought I'd ask on here as a last ditch effort.
I am looking for music management software (that runs on Windows) that supports both streaming from an Android device over the internet (ideally it has an Android app) and synchronizing an iPod.

My current set up:
  • iTunes as music management software, in order to synchronize my iPod.
  • CloudPlayer to stream from my Android device (all of my music is on Google Drive).
  • iSyncr to synchronize select playlists from iTunes to my Android device.

This set up isn't terrible but CloudPlayer does not feature all of the playlists I have in iTunes nor does it allow me to sort by iTunes fields (date added, etc.). I could technically just sync all of my music to my Android device as well but I don't really want to use up 40GB on my device for this purpose when I have a data plan large enough to support streaming on demand.
How to fix that error in chrome?

My receiver will only play output on one mode. If I first ask the Echo Dot to play high quality music from an internet source it plays through the receiver. Then when I change mode on the receiver over to TV and ask the Echo Dot a question, e.g what time it is, it won`t answer over the receiver.

I am thinking of connecting my Echo Dot to PC speakers and the receiver using an audio mixer that has multiple outputs. Will it play over the Hi-Fi system or just play over PC speakers?

The problem with my receiver is that it needs to be on a certain mode for the Echo dot to respond. I want the Echo dot to respond no matter what mode the receiver is on.

Thanks for all your help,
I am currently setting up my home cinema room, where I want to control everything using my Echo Dot. I have set up Sky Q, Amazon Fire TV stick, Blu-ray player, etc.. to my  receiver, where each device has its own channel. All of that works perfectly.

As I`ve mentioned, I want my Echo Dot to control everything. Because of this I want the Output from the Echo Dot to come through the receiver, no matter what channel the receiver is on,  i. e. if I am using Sky Q I still want to be able to talk to and hear the Echo dots.

Does anyone have a solution I could apply?

Do you know how to convert a file that is AIFF-C Audio to MP3?

I have an audio file that I had recorded about 20 years ago, but need it updated to MP3.
An online reviewer downloads tens of thousands of video and music files and it is a real mess with no organization. Additionally they have some on their laptops, others on their PCs and then some on several servers, with a few on MACs. Fortunately the MACs are few in number so I can manually move all those files but for the rest I would like to be able to take all the files, use their file names and create folders with the name and then move all the files with matching names into the matching folder. Looking at the video files (most of which are TV shows) they have a fairly consistent naming convention which I hope will make automating this process possible. Generally speaking the name of the video files are "name of the TV show then season number then episode number", example "Americas Got Talent S02E07". So would it be possible to take all of the name but not the S02E07 and create a folder "Americas Got Talent" and then move all the files that match that name into the newly created folder. The MP3's (mostly music but some are podcasts) do not have this "consistent" naming convention so not sure what to do here -- but if I can get the videos organized I think switching them to Media Monkey for future podcasts and music should provide the organization needed. Thanks!

Alas I've never lived in a place large enough that a Sonos system would be a better solution than turning up the volume loud enough to be heard in the few small rooms I have.
Yeah, pretty much the same here. It would have been handy for a few parties, but at only ~1/year, it was hard to justify a Sonos vs. the "good-enough" approach of turning up the volume.

One of the perks of moving back East, we can actually afford real estate now ;)
I recently tied to start another band,
and connected with a very experienced drummer on craigslist, she drummed for the Peppers in Raleigh when Chad was in rehab.
I attended that show and remembered her well, for an elderly female drummer to be with them.

Anyway, I Messed it all up. I said initially, that of all the 40+ songs I had written, we could try 'em out at my house.
I suggested I put them all to sheet music (regular staff notation) as she had some neighbors interested in playing with us.
Anyway, I couldn't find time to do the songs justice on sheet. I thought staff would be good, for the melody being solid there,
Maybe with bass notes, and chord/tab signatures. It really infuriated her and she jumped ship.
For my piano songs, sheet music would be ideal. - as I can sing Phantom front to back, and have the full score from my voice / choirmaster coach.
To connect with new musicians/people, I don't want them to turn up and I have nothing on sheet, to prove I am not a clown. I want a few dozen songs on sheet.
Do you think competent musicians will be okay with just the full lyrics with chords above the words? In my first band, we just had chords and assumed/learned the melody as we got to know the song.

What is the best play here?
I'm also considering creating the band out of just millennials, as nothing else has any traction these days. Just for them to play my music. I can be a semi- manager. Would that revolt millennials? I don't care about fame or …
Hi experts

I saw this boombox at Best Buy.

The important features that I need are am/fm radio.

The reviews I read on this are mixed. Sound reviews said this boombox doesn't sound good.

Do you guys know a boombox similar to this one but that sounds good? It must have am/fm .
Even if it costs more.
I was in a band in late nineties college,
am 39 now, single, set up financially, don't want to sneak into the decimated music industry now. I'm not going to sing for a 90 second trial in front of Simon, etc for AGT. I am of the Nirvana/Pearl Jam, don't care about clothes and 80's hair band superficiality. Online song submission venues still mention to bare in mind your image and personality. Hah! It never dies off. If I dye my hair pink like Kurt Cobain, the old bastards I have wings-night and watch football with won't be impressed.
Playing live 'round town now is more invisible than playing at an old age home, which I did once with my Novell colleagues, btw, and also at a metal institute!
But, it's the millennials that comb these sites for new music. How? Where? How can I insert my music into the millennials' radar?

If I'm not myself a millennial, is music a waste of time? It feels like it. As a 19 year old, I digged DMB, but he was all over the radio, and TV. I can handle doing it for myself and satisfaction of live play. Is that all there is for non-millennials? Dave Matthews was 36 and the others in DMB were old like me, too.

Currently some of my coworkers are using individual streaming sites to listen to internet radio on their computers. As responsible IT-admin I'd like to reduce bandwith-usage of these kind of streaming sites by providing my coworkers with a different solution.

I was thinking about a server that broadcasts one or two radio stations and a tool/website/device on the client side receiving them.

I am excited to hear your suggestions!

When playing MP3 audio files in VLC media player, how do you use hotkeys for [Pause only] and [Play only]?

In VLC media player, going to Tools > Preferences > Hotkeys results in the following window:
As can be seen, pressing {Space} is the default setting for toggling between [Play] & [Pause]. This hotkey works great.

Also shown however, are the hotkeys (Browser Stop & Browser Refresh) for the actions, [Pause only] & [Play only] respectively.

What do the latter hotkeys refer to? In other words, why would you even need to have a browser (eg Chrome) open in order to play MP3 files using VCL?

(Note: My understanding of the above two actions is that unlike toggle, which changes Play/Pause to the opposite of its current state, [Pause only] will pause the recording if it is currently playing but if currently paused, will leave it unchanged. And similarly, [Play only] will begin playing the recording if it is currently paused and if already playing, will leave it in that mode.)

The following two screenshots show how hotkeys can be modified:
 2017-08-22f_EE.png 2017-08-22g_EE.png
And the next screenshot displays the results after changing the hotkeys for [Pause only] & [Play only] to {Alt+s} & {Alt+p} respectively:
The problem however, is that when VLC is active, pressing either of those hotkeys has no effect.

What would prevent those hotkeys from working and what other shortcuts are available for activating [Pause only] & [Play only]?

It's certainly possible, with MIDI notes,

but has anyone developed virtual guitarists for DAW's that can play a melody, solo as well as a Brian May or Stone Gossard? Queen, Pearl Jam - I had 'virtual guitarist' for one of them, but it could have been better, maybe I hadn't explored enough..
What might I consider? For strumming, as well? I have Logic Pro, Cakewalk also.

I need to make a movie of my desktop with my own audio narration.

I have used Audacity and love it.

Is there a simply to learn tool that would let me record my desktop and either edit the audio with this tool or just let me edit the audio in Audacity?

There will be periods on no activity on my desktop, so I can adjust the age views to fit the edited audio.

Is Adobe Premier overkill? The cost is very high.
Client has audio files from town meetings that need to go on website.  Site is due to launch as early as next week.  Largest file size is 341MB.  Website is being built on Wordpress.

Can someone recommend a software or plugin we can use to reduce the file sizes.  They are not tech savvy so it would need to be something pretty easy to use since they do not want to have me do it for them on a weekly basis.  

They might be ok with a free trial and then pay afterwards if it serves their needs.
Is there any good software (free or with minimal one time fee) can you introduce in composing some commercial standard music?

Also just curious what software are used by those recording companies?

Thank you.
I installed Audio Hijack and and SoundFlower.

I see SoundFlower in both MicroPhone and Speakers for Skype...

Which do I use?
