Deinterlacing in Handbrake!
I have to admit that I think Handbrake is really one of the most useful freeware available for the Mac. I think it is even better and more polished than many commercial applications. The presets included with Handbrake are perfect most of the time, but it happens that the source DVD is interlaced. Handbrake thankfully includes a deinterlacing feature, but it does slowdown the process and not all the source DVDs are interlaced. What I started doing was checking out the one frame preview that you get when you click on "Picture Settings..." and I only enabled deinterlacing when there was interlacing issues. It did happened that it was interlaced and it wasn't visible on the preview frame. The solution is that Handbrake lets you check out up to ten frames. You can switch the preview to another frame in the "Picture Settings..." by clicking on "Next" or "Previous". About what speed of deinterlace you choose, that depends on whether you intend to keep the final result for a while. I tried all Fast, Slow and Slowest, but I didn't really see a difference in quality that makes it worth the extra time for me. I usually get between 50-60 frames per second at Fast and around 5-6 frames per second at Slowest (Quad Mac Pro). No Deinterlace is about 10% faster.

What does Handbrake do?
Hi, I downloaded Handbrake a while ago, and about last week, it told me that I had to download the update. I did that, but now the application doesn´t open. What could be happening? I downloaded it again, also from other webpages (not the official), and it still doesn´t work. Does anybody know if there is some problem with the update, or is it something else? Am I doing something wrong?
Joe, I just ran into the same issue you did. If you're running leopard (OS X 10.5), you must download the new update. But if you're running Tiger (OS X 10.4), Handbrake will continue prompting you for an update that will not work for your system while rendering itself useless. The quick fix, however is to simply go to Prefrences in handbrake and uncheck the "Check for updates" at start, and you should be fine.
msgunzelman, Handbrake is an open source program that allows you to rip content off DVD video to MPEG files to be viewed on programs such as Quicktime or VLC.
I've had handbrake quite awhile, and back when i didn't know too much of how to use it i had problems finding a good setting to use. So for those who had the same issue, i'll post the setting that i use to rip my dvd's to be viewed on apple tv.
To get a good, dvd-like quality file that works on apple tv, itunes, and quicktime (but not iphone!!), i've found that the "normal" preset works best, but change the average bitrate to 3,000 (from 1,500 i believe), and use "2 pass encoding" (i've never messed with the "turbo first pass", i'm not quite sure if its even faster, or whether it takes away quality. Since i'm trying to get the best video quality out of my movies, i just keep that turned off.)
With these settings, a 2 hour movie will be 2.25 gb, quite a large file but the quality is superb. I had some problems with the audio cutting out for a few seconds about halfway through just a couple of my movies, so i would recommend checking that out, but i read that the new version fixes that.
KEEP IN MIND THAT I HAVEN'T DOWNLOADED THE NEW VERSION OF HANDBRAKE AND AM STILL USING VERSION 0.9.1 DUE TO THE FACT THAT THE NEW VERSION DOESN'T WORK ON MAC OSX TIGER
to rip a dvd to play on an iphone isn't all that hard, just use the iphone preset they already have built in, and since iphone space is limited, i've dropped the average bitrate down to 800 and since its such a small screen the quality looks really good. i also clicked the option of "2 pass encoding" because i read somewhere that it reduces file size and makes for a better quality encode. I just know that it doesn't actually start writing the file until the second pass through.
Hope that helps you guys out, and if any of you know of a way to use a file on apple tv AND iphone then please comment and explain
well I don't even know what interlacing is. Can anybody inform me? I use mac the ripper and then i use dvd2one to burn it. Is this not a good method? Back when i was a windows user it was much easier but maybe its because I'm just not educated in the matter.
Travis, Deinterlacing is basically in laymans terms a way to usually make the DVD look better.
What happens is because of standard TVs (non-HDTVs), images are actually only displaying half the image, but they show it SO fast that the human eye can't comprehend the difference. 720p and 1080p are both full frame rather than interlaced, which is one reason why they look much better.
So by deinterlacing a DVD you usually can make the image quality a bit better. Sometimes it doesn't actually work, but most of the time it just makes your DVDs look smoother once you have ripped them to your computer. I hope this helps.
does anyone know any free diagram apps i badly need it?
I am having a problem with handbrake. I recently downloaded it, and once the DL is complete, I get a virtual drive on my desktop. I pull the App out and delete the "v-drive" but when I CAN access it, I the v-drive back on my desk top. What do I do to remove this?
Thanks
Chris,
Its because you took the file from the mountable disk image .dmg and your using that to open the program, so it has to open the disk image every time you want to use the program.
Instead, always take those files from the disk images and drop them into the application folder of finder. NOW take the icon from the APPLICATIONS folder and put THAT ONE in the dock. You put the icon from the image in the dock, and thats where its looking for it.
Remember, in macs, programs are just folders. You move programs by moving folders. You can take that folder and put it in another macs applications folder and it will work.
Handbrake converts my interlaced source to progressive. It's interlaced video recorded from the TV. Of course I want to keep the video interlaced. I would not be that stupid to convert it to progressive, but Handbrake does. Even when I set the "progressive" option to "Off". Do you know what the right options are? Thanks a lot.
Nikita Smith: You are absolutely wrong about interlacing.
Interlaced video looks better when you leave it interlaced.
The top and bottom fields of a frame belong to different "photos", which were taken with a difference of 1/50 seconds. So, if you convert this kind of video to progressive, you will discard one of the fields in each frame, and will lose half of the vertical resolution.
Deinterlacing would only be applied when interlaced source has to be displayed on cinema screens.
It's a pity that powerful software is at hand of beginners. They are destroying good interlaced sources by converting them to progressive.
