OS X V10.6 Snow Leopard :: Transcoding A/v Files Without Loosing Quality?
Feb 16, 2012
Is there a free app that will transcode a movie without loosing any of the size or quality? I essentially just want to reformat the file from .ogm or .wmv to something more mac friendly.
Info:
Mac mini (Early 2009), Mac OS X (10.6.8), 1Tb External Firewire HD
Transcoding from mpeg PAL to MP4 1080p in high quality with MPEG Streamclip seems to take a lot of computing power. I observe that the Mac Pro does not use the 12 GB RAM I have and I suspect it cannot utilise the HD3870 capabilities. Does anybody have ideas how I can do this faster with my hardware?
I wasn't sure where to post this, so I hope this is an okay location.
I recently read that if you open up a jpeg file and then resave it, it loses quality. Is this true?
Is it only Jpegs, or all compressed images? Or even yet, all images i.e. Raw? What other scenario must I be aware of where file quality can be lost? Any with music files, or video files?
I transcode M2TS files into PRORES (HQ) using PAVTUBE. Final cut X takes a long time rendering them. Also in playback, the audio appears for a second and disappears to reappearing another second, for the entire clip. Is it normal ? Is there a better way to import m2ts files ?
I have a 24" iMac (purchased last spring) and an HP Deskjet 842C inkjet printer. The photo print quality was quite good under Leopard, but is very poor under Snow Leopard (I'm using the latest updated version 10.6.1 with the Gutenprint print driver, 5.2.3). The images have a noticeable bluish cast, and considerable banding. Changing the print quality and paper type does not solve the problem, in fact, the image quality usually suffers. HP has not updated the drivers since 2005.
I just tried using iChat for the first time in SL (I usually use Skype) and experienced something *very* odd.
First, the specs: Late-2007 MBP 2.4 GHz Core 2 Duo 4 GB RAM GeForce 8600M GT
The problem:
For the first few seconds of a chat, the video quality was gorgeous. But then my hard drive(?) (could've been the fans, I dunno) would start getting really loud (it sounded like a particularly intense Time Machine backup) and the video got extremely "blocky" until it was basically useless; after a few minutes the audio started to go, too.
We tried this a couple times with the same results. I rebooted my computer & AirPort, but no change.
My chat partner experienced no problems with audio or video (he's also on SL).
According to SpeedTest.net, my connection speeds are 12.31 Mb/s down/1.13 Mb/s up.
Skype and Google Talk video continue to work just fine.
I am struggling to reduce the size of some of my PDF , without loosing image quality. Â I have used Finder and it did reduce size , but the the picture quality was poor.Â
Firstly, the video doesnt play with anything except VLC on a Mac... quicktime simply replies with the message "An invalid public movie atom was found in the movie" and refuses to budge.
Secondly, I have a full version of VisualHub and Handbrake. Till date VH has never failed me but all of a sudden it says that 5.1 AAC is not supported.
Using Handbrake and the iPhone preset results in a disastrous transcode with ghastly sound effects like those in a horror movie... I later gathered that it was the same sound but playing at an extremely slow pace.
I am running Snow Leopard on both an iMac and a MacBook Pro. On the MBP I can play an AVI file. On the iMac, I cannot. I get an error saying "The document could not be opened. The movie is not in a format that QuickTime Player understands."
I can't open zip files. Archive utility flashes and disappears. Archive utility does not seem to be in the utility folder. Tried repairing permissions and verifying disk.
I'm uprezzing clips from a public domain flick to match my FCPX timeline of 1080i. (Might as well to see how it looks.) The public domain flick is 24fps. Should I change it to 29.97, or does it matter?
If I should change it, what choice do I choose in the retiming panel? 30@29.97? 29.97@30?
I have read the 3 or 4 discussions on flashing the 4890. I just ordered one and plan on doing a clean install of snow leopard and installing the card at the end of the week. However, some of the links from rapid share don't appear to be working. Can some one point me to where these files have moved and are there an snow leopard specific files?
So i'm getting my first Mac tomorrow, and i'm going to switch from using iTunes on Windows to using it on os x. will I be able to copy my library off of my ntfs formatted external hdd to mac os x.
I received the Snow Leopard upgrade disc, single license for Christmas. I Installed the software, and i noticed my icons were changed for the finder and dashboard. I couldn't use my candy bar anymore since the free trial was done, so i decided to download and try liteicon. I changed the icons back and deleted the application. Now My computer when i try to download the updates for snow leopard upon restart it wont boot past the grey screen with the apple logo and the loading gear. The only way i can restart or turn the computer on after being shut down is by booting on the disc and reinstalling the snow leopard again. What the heck can be wrong here?
I am running snow leopard on the 27" imac and for some reason when i try dragging files onto the USB that i have inserted it does not let me copy the files? It doesn't do that with the other USBs i don't understand why this one is not letting it copy. It reads it fine.
The external drive has a copy of my old system 10.5.8 with everything on it including CS3/ Office 2008 and even iTunes. Those along with many of my desktop folders which had reference photos were almost entirely corrupted.
I was one of the unlucky ones to get this Trojan bug so decided to erase my disk and reload the system. In doing so, I did a lot of dragging from the backup to the new system not knowing how to restore and I did not want to bring this bug with the restore. So, here are my issues so far I am unable to resolve. Â
Address Book and Calendar are empty and I am unable to find the back up files to re-load them.Â
Also in Safari I am unable to find my bookmarks. Is there a way to find these files or am I out of luck?Â

I am trying to speed up Re-Labeling all my metadata for every song in my library. Basically I need to create a workflow first, but I am having some troubles on how I should be doing it in Automater.
Example filename: "forrestaveryderty_driftinonby_flapjack.m4a"Â find all filenames that start with the same word before the First underscore (_)Â create a folder with that same wordÂ
copy files with the same word (BEFORE THE FIRST UNDERSCORE) to their corresponding folder name I then can use Media Rage to select the certain folder and and change the artist name all at once. and I would like it to do that with every file at one time.Â
again...Â
1: Find files with the same name before the first "underscore"
2: Create a a folder for every different name found (before the first underscore)
3: Copy found files (with same name before the first underscore) to the folder with the same name
When ever I move any file to the trash, or choose delete from the file menu. Snow Leopard always warns me that this file will be deleted immediately and can not be recovered. How do I get the trash to function again?
Lately I'm having trouble downloading pdf files that are open in the Safari window. I'm using the latest versions of Safari Adobe Reader on an IMac OSX 10.6.8. I used to download them simply with "command s", now it says "the document ... cannot be exported".
