Higher Bit Rate for h.264

The people at FiOS say my h.264 QT file needs to be 6 MB Bit Rate, but I can't seem to get higher than 3 MB. They have to sample it up which makes my graphics slightly soft.
Can I get a higher rate using Compressor and h.264? I'm past deadline and don't have time to try other formats today, but will listen. Thanks.

Increasing the bitrate alone should not have any effect on the image (i.e., a sharp image is not going to become soft because of an increase in bitrate. Decrease yes, increase no.)
It seems that there is something else going on. Most likely it is the resolution. If the resolution you are using is lower then what they need, then they are scaling up the image which causes the graphics to become soft.
The bad news is that there is no way to "fix" this. You will need to start all over again at the proper resolution.

H.264 .m2t high bit rate playback problem ...

I'm still coming up to speed on some of basic video concepts so bare with me.   I have a 9 minute 1280x720 video; 59.94; source came from a Contour+ bike helmet type camera that stores .mov/H.264; separate audio track from MP3 files.   I exported an .m2t file file using the H.264 Blu-ray format/preset.   Besides checking TS multiplexing, the only other items I changed from the default were Maximum Render Quality and VBR, 2 pass.   This file plays fine on my PC with Windows Media Player.
Next I went down the layman's road of thinking higher bit rate = more information per second = higher quality and slid the target bit rate all the way to the right to 35, which in turn adjusted the max bit rate to 35 as well.   VBR 2-pass, max render, etc. still applied.   When I go to play this .m2t file under WMP it chokes and jerks.
I just wanted to ensure this result is expected and not some issue with my hardware or software configuration or other underlying systemic issue. I was expecting this file to play just like the other one above.   Feedback?
I have a new PC that followed the VideoGuys DIY9 spec closely: i7 3930, 32GB, GTX670, WD Caviar Black RAID0, etc.
Thanks

WMP overall is a pretty unreliable media player IMO. The media players I tend to stick with are VLC,Splash Lite and KMplayer. In my experince sometimes with interlaced footage VLC doesn't play it back very well if it's a scene that has a lot of movement regardless of how you tweak it's deinterlace filters/options etc. So in those cases I use one of my other media players.
Basically what I'm saying is that no media player is perfect for every scenario although WMP is certainly my least favorite.

[Bug] iOS 5.1 missing covers after "convert higher bit rate songs to" with iTunes 10.6

All my music has covers in iTunes Library. But after i updated to iOS 5.1 they are missing on my devices.
It happens every time i check "convert higher bit rate songs to 192/256 kbps" on iTunes 10.6 (40) on my Mac.
On the screenshot (iPad 2010 running iOS 5.1) Bon Iver's album copied by default settings, and Coldplay's album converted to 192 kbps.
BTW on my old iPhone 3G (iOS 4.2.1) all covers are OK even when convert feature is ON.

I have solved it by unchecking (momentaneously till apple fix it) the "Convert higher bit rate songs" option.
I know that it need more space but i don't have too much music synced so.. it isn't a problem for me..
I have this problem because i'm using the "manually manage music and videos", i'm not using the auto sync option because iTunes always try to copy my new apps to my mac even having that option unchecked...
Now we have iCloud... i don't know why apple still have not deleted this feature!
Anyway... i have solved it momentaneously.
Apple.... come on!

HT1535 How do i convert higher bit rate songs to 128 kbps AAC

I am trying to sync selected songs to my Iphone 5 from my itunes library. I have recently taken my computer to be fixed and all of my music documents were taken off but the files were replaced shorty after. I re-downloaded itunes and it is up to date. My iphone is also on the ios 7.0.4. Whenever i plug my phone in to be synced it never goes past the "waiting for changes to be applied" step. While my phone was still connected i went to the "On this iphone" tab and clicked the autofill button and a message came up that said i must convert higher bit rate songs to 128 kbps ACC to allow the songs to be copied to my iphone. How do i do this? Also, once this is done will it solve my problem with transfeering my songs from my library to my iphone?

Sid,
With the device connected, click the Summary tab and you will see the "Convert higher bit rate..." option. Set it to 128. See picture below:

Using the "Convert higher bit rate songs to 128 kbps AAC" feature...

I recently discovered the "Convert higher bit rate songs to 128 kbps AAC" feature and used it to copy my entire 70 GB music library to my 64GB iPad. The music library now occupies only 45 GB. Awesome!!!
Unfortunately, the whole process took well over 24++ hours on my quad core Windows 7 computer (takes about 6 seconds per track). Questions:
1. Is it possible to speed up the process? Even though I am using iTunes 64-bit version, it seems that at no point is more than a single core being used at 33%. Seems to me like overall 8% of the CPU (33% / 4) capacity is being used for the conversion and 92% is being left idle. Is this just bad programming or is there anything I can do to speed up the process? Others see similar problems?
2. Now I have already started dreading the day, I need to restore my iPad (e.g., when OS version 4 becomes available). I would hate to have to do this process all over again. Should I need to restore my iPad, is there anyway I can force iTunes to back up the 128-bit AAC versions on my computer and restore it up from there?
Any insights into both these questions will be deeply appreciated.
Cheers,

Thanks for the response.
So, I am wondering why iTunes uses only 8% of the processor power in converting the songs.
Possible reasons not to grab more of the CPU power (1) maybe the process is I/O bound due to all the writing, and is not processor limited? (2) since conversion is almost always a background program, and the user will typically have other things going on, maybe it intentionally limits CPU use?
I ran a few quick experiments (out of curiosity) and think the answer is #2. No apparent technical reason but potentially a limitation introduced by Apple's engineers to maintain a good user experience (for some people at least). I fired up 4 instances of dbpoweramp and ran multiple conversions and found that the process goes faster than what iTunes can do by an order of magnitude. With luck, someday Apple will have an option for users to select how much of processor bandwidth to be allocated for the conversion.

How do I change the bit rate for dls?? How times can I download one song??

I'm new to iTunes. I already downloaded 3 songs when I realized that the default bit rate is 128Kbps. I tried changing the bit rate to 192Kbps with a (Variable Bit Rate) checked.....unfortunately when I downloaded the next 2 songs the bit rate turned out to be the same.
Do I have to restart Windows or iTunes before downloading again?
And now that I have 5 songs with a lower br than I wanted... in order for me to have(download) the song at the higher bit rate...Is it possible to download one song more than once?
Thanx.

You have no choice as to bit rate when purchasing from the iTunes Music Store. The official bit rate of all tracks there is 128 kbps (a very few have been reported to be at higher rates, but that's not a choice you can make, it's how the track was encoded by the record company). The setting in the iTunes Importing preference is for tracks you import from CDs only and has no effect on iTMS purchases.
Is it possible to download one song more than once?
No. Except in extraordinary circumstances, the iTMS allows only one download per purchase.
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Discussions page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic before you post a question.

No E-Mail Updates or High Bit-Rate Audio Using WiFi

When I use WiFi and click on the mail icon, my 3GS will not update my e-mail messages. The network activity icon just keeps going and going. Additionally, I cannot get audio streams over 128k on apps such as Wunderradio. Everything works fine on 3G networks and I have enabled the high bit rate option for the apps that have such an option.
The two problems happen on all Wifi networks, so the problem isn't my home network
Anyone else have this problem or know how to fix it?

Yes. I am able to surf the internet and do everything else except for the two problems I outlined in my original post. The icon switches from 3G to the WiFi "fan". Using the Speedtest.net application I have checked my WiFi connection and it is usually at 4,400 kbps download and 1,000 kbps upload.
In case someone asks: I am using an att.net e-mail account, but have also tried my comcast.net account with the same results.

Super-rip high bit-rate with x

hi everyone, i was wondering if anybody with the x-fi notice the high bit rate. mine is that high it will not play on a cd player in .wma or .wav, with or without cmss3d, i found that the bit rate i get without cmss3d it's around about 2200bp/s. when cmss3d multi channel it shots up to approx. 5500bp/s. medium settings. anyone else with high bit rates.
john
thanx for any replies

john_g,
If your CD player are not able to support/playback 4/6 channel Wave or WMA Pro/Lossless file. I would suggest you to super rip to normal WMA audio file instead. Choose CMSS-3DHeadphone option instead of CMSS-3DSurround. From there you should have an option of WMA with bitrate of either 92kbps, 256kbps and 320kb
ps.

What does convert higher bit rates songs to 128 kbps mean

what does convert higher bit rate songs to 128 kbps mean?

Some people, myself included, import their music from original audio CDs. When doing so I choose to import using Apple Lossless format so as to keep the full original quality of the audio CDs (this is after all why it is called Apple Lossless format in that you are not losing any quality).
The drawback of doing this is that the music files take a lot more disk space than a lossy format like MP3 or AAC. This is these days not a problem on a computer as hard disk space is now cheap an plentiful but it can be a problem on a flash memory based music player like the iPod Shuffle, iPod Nano, iPod Touch, or iPhone as these have far less capacity.
Therefore Apple now let you turn on this option to automatically convert from Apple Lossless to AAC when syncing to one of these music players. As a result on your computer the music is still kept in the full lossless high quality format, but is converted and transferred as a much smaller but slightly lower quality for use on these music players. As with an iPod you are not listening in a quiet room with high quality speakers you will not really notice the difference in quality.

Music Skips Some Songs After Choosing "Convert higher bit rate songs to 128 kbps" Option

I have so much music and choosing "convert to 128 Kbps" option makes it from 18 Gb to around 6 gbs but sometimes a few songs are ther

Meg St._Clair wrote:
"Convert" tends to be a confusing term. What iTunes does is make another copy of the track at the lower bit rate for transfer to the Shuffle. Your original, higher bitrate file remains untouched.
Actually, iTunes converts the track on-the-fly while loading it on the shuffle. NO copy of the downconverted track is kept. The same process will occur IF you decide to delete the track from the shuffle and then happen to want to put it on the shuffle again.

When I Tick Convert higher bit rate songs to 128kbps and press sync it says are you sure you want to remove apps. Help please

Hi, I recently put music on my ipad (manually, I do not sync because I dont like leaving music in my itunes) I realised they take up a lot of space because of the bit rate so I went into iTunes and pressed "Convert higher bit rate songs to 128 kbps AAC" Then I pressed apply and I got the message "Are you sure you want to remover 113 apps......." I have checked and sync Apps is unticked so my question is why does it say this and is there a way around it. Also if i tick convert to AAC will it convert the songs already on my ipad or just ones I add from now on.

Why not? That's what it is for.
So Restoring your iPad when it crashes and losing all your music is acceptable to you?
Then I pressed apply and I got the message "Are you sure you want to remover 113 apps......." I have checked and sync Apps is unticked so my question is why does it say this and is there a way around it.
Since you now want to sync the iPad and have told it you do not want to sync apps, it will remove them all.
Check the apps you want on the iPad.
Also if i tick convert to AAC will it convert the songs already on my ipad or just ones I add from now on.
It will only convert new songs added to the iPad.

Convert higher bit rate songs?

This is an option on the device screen every tme I sync my iPod touch - now at OS v6.
Should I click on it and convert? And if so, to which kbps setting?

On-the-fly conversion is only available on the iPod shuffle. The iPod shuffle (probably because of it's limited capacity) has the option to "Convert higher bit rate songs to 128 kbps AAC". This option is not available for any other model iPod. Syncing anything larger than a shuffle and converting in the process would be a very slow process. For the larger iPods the files have to be converted in iTunes first or indeed have to have been imported in a compressed format prior to transfer.
There are a couple of ways to handle this, one is to convert the songs in your library and put them in a playlist to sync the iPod from, the other is to have a second library of compressed songs and sync the iPod from there:
iPod - Syncing Music
Using multiple iTunes libraries -Mac

HD SDI versus Component... Which has a higher bit rate?

New system is up and running! I'm importing HDCAM footage through my decklink HD Extreme. Wondering what would yield a higher bit rate- the HD SDI input or the component input...? SDI is giving me about 95 mbps, but 4:2:2 uncompressed 8-bit HD is supposed to be as high as 150 mbps.
Side note: I'm using a BNC cable for the SDI input.

Same bit rate, only better quality via HD SDI.
Make sure you are using an HD SDI BNC cable...not just any BNC cable will do.
If you capture via Component...then HD SDI...you'll note the same bit rate.
SDI is giving me about 95 mbps, but 4:2:2 uncompressed 8-bit HD is supposed to be as high as 150 mbps.
AS HIGH AS...meaning there is a range. uncompressed 10-bit HD ranges between 150 and 180 MB/s...depending on the frame rate...23.98, 29.97, 59.94...and the size...720p, 1080p.
TOO MANY SECRETS...er...OPTIONS.

Higher bit rate duplicates...

I recently lowered the bit rates for all my song files in itunes, but now I have duplicates of both the new lower bitrate, and the higher bit rate as well of each file. Is there anyway to delete the higher bit rate files all at once without deleting my whole entire library? I know I can display all the duplicates at once. If I uncheck the lower bit rate files, but keep the higher bit rate files checked, can I still delete the higher bit rate files at once without deleting every file?

Sorry it took some time but there was some other housekeeping to do on the script.

Re-encode high bit rate music during sync?

The iPod Shuffle has a great feature during music sync which allows you to have iTunes automatically re-encode high bit rate music rates to 128kb/s AAC during sync. There doesn't appear to be a way to enable this option for other iPods, including the iPhone.
Does anyone know a way to get this functionality for the iPhone? With the amount of apps and photos I have on my phone, it leaves little space for music and my entire collection is high bit rate.

I'm not aware of a way to get this functionality with an iPhone. Lowering the rate for music in your iTunes library which was encoded at a higher rate when imported into your iTunes library reduces the sound quality more than if the chosen lower rate was selected for the encoder option when importing the music originally.
Depending on the available storage space on your computer, or on an external drive for your iTunes library, you can re-encode the music you want transferred to your iPhone followed by placing the lower rate music in an iTunes playlist that is selected to be transferred to your iPhone.
