[Phil Peacock] “Not sure what you mean. You want to delete something that isn’t there?”
No, he wants to delete something that is there… silence.
He is looking for a script that will find all of the areas of silence in your video and cut them out. It’s a very common task for videos that are left continuously running and you only want the parts that actually have something happening based on audio.

[Michael McIntosh] “What should I do?”
Here are four (4) things you can do:
- Reinstall QuickTime because you need it to work with MOV files in Movie Studio.
- Ignore the fear mongers who love to report on vulnerabilities because they sell anti-virus software.
- Windows has more vulnerabilities than QuickTime… maybe you should uninstall that too?
- Buy a Mac and stop worrying
#1 of those four will clearly fix your problem (the others are optional). 😉

[Kathryn L Beranich] “Might be time to jump on the Premiere wagon! I appreciate you getting back to me.”
Why would you do that? Why not upgrade to Final Cut Pro X. If you were using FCP X you could have dropped those AVCHD files onto the timeline and been editing a long time ago. FCP X edits AVCHD natively.

Wow, that’s pretty convoluted. I don’t think any of us would have figured that out. I didn’t even know there was a super administrator. I know lots of people have installed Vegas Pro on Windows 10 (including myself) who didn’t have to do that but I always used clean install of Windows 10. Perhaps an upgrade from Windows 7 has caused this problem?
Anyway, thanks for getting back to us and letting is know. this will certainly help someone else out who may be having the same problem.

[John Hughes] “So given your explanation above, video shot at 24fps progressive at 50Mbps like my camera captures would be better quality (relatively) than 60fps progressive at the same bitrate – since more bits are being represented in each of the 24 frames?”
Yes, that is correct. There would be a huge difference between 24p and 60p at the same bit rate because you have over twice as many bits available to encode each frame.
[John Hughes] “Is it then just a matter of choosing a higher frame rate if you don’t want the ‘juddery’ look of 24fps (for like say fast-action sports), that you would be making a sacrifice on a little quality? A trade-off so to speak with smoother movement but less overall visual quality?”
Yes, but you don’t need to deliver 60p to get away with the jittery look of 24p. 30p is still a nice compromise.

[John Hughes] “So I’m learning that the max bitrate of say Blu-Ray is around 40Mbps but that’s more for pressed Hollywood media and that standard Blu-Ray is about 20-25Mbps. If I am delivering the final product as a Blu-Ray, it seems then that I may be losing a lot of quality going from source to delivery (50Mbps to 20ish Mbps)?”
Quality is relative. Will you see a quality loss? It is possible because you have seen the original, but then again you might not. Will your audience perceive a quality loss? Absolutely not! It will look like great HD to them. Blu-ray was created back when high quality HD was 25Mbps. The days of DVD where a acquisition formats didn’t change for 10 years is over. From here on out, you will never be able to deliver in the quality of your acquisition because formats are changing too fast for players to keep up. Just accept it.
[John Hughes] “I’ve also heard of people using higher bit rate renders for posting video online. Is online video the best medium available from which to post the highest quality content? “
The majority of the world doesn’t have the bandwidth for video bitrates that high so unless you only want to appeal to people in large metropolitan areas. Forget about that too.
[John Hughes] “And can someone help me understand 2-pass vs 1-pass encoding? Is this just for encoding video that goes online and not with DVD/Blu-Ray media?”
1 pass encoding makes an educated guess at how many bits it can use for each frame in order to stay within the average. Two pass encoding make an initial pass taking note off exactly how many bits each frame needs. Then it makes a plan on how to best allocate the bits given the average rate, and then makes a second pass where it encodes each frame at exactly the bits it needs (no guessing). Two Pass yields higher quality for a given average bit rate. This applies to DVD, Blu-ray, on-line, whatever.

Check that you don’t have some anti-virus, anti-malware, anti-anything turned on that is reversing the install. I’ve seen this happen before. Disabling the anti-software fixed the problem.

You can feather the edges of a mask. They don’t have to be sharp. It should be simple to create that mask in photoshop or illustrator.

[Craig Seeman] “Flip4Mac Player Pro $29 is a Quicktime Component that works inside Compressor and will convert WMV to ProRes when used that way.”
I didn’t know that. Good to know.

[Francesco L'Erario] “Could you please suggest me a free software to convert them (if it is possible using a batch) so that I can edit them in fcpx?”
I use Smart Converter to convert to and from Windows WMV files. It uses ffmpeg under the covers which is a very popular open source converter. The free version does not have batch capability but the Pro version does for only $14.99 USD. You can convert the WMV files to MP4 which will allow you to edit them in FCP X.
[Francesco L'Erario] “And, since I’m interested in buying Compressor, should it be possible to convert them with it?”
No, Compressor will not accept nor create WMV files.
