<b><span style="color: orange;">If you do not understand the RF:xx, read </span><a href="http://viconco.blogspot.com/2010/07/shrink-you-video-files.html" style="color: orange;">Shrink your video files</a><span style="color: orange;"> first.</span></b> </div><br />
<div style="text-align: left;">While encoding and re-encoding HD material RF 25 is fine, when I started to encode my ABBA DVD to MP4 I ran into some quality problems with RF 25.</div><br />
The problem is that the material from the ABBA DVD is from the 70th. There is lot of grain and the videos are quite soft.<br />
RF 25 normal just smoothens over all the grain and there is a noticeable loss of fine detail.<br />
This is the DVD original (you can see the black lines top and bottom what HandBrake removes automatically).<br />
Notice the detail in the fur and the face.<br />

For the highest detail in bad material RF 20-22 might be the way to go, but if you have a bunch to encode it is good to make some samples first and compare for the quality you want.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5899112496273323949.post-42032286378850474372010-11-25T13:05:00.000-08:002010-11-25T04:07:04.741-08:00HandBrake Batch EncoderRe-Encode and shrink hundreds of bloaty AVI files or your digital camera clips with just a few clicks to less than half the size with the same quality.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_HXaPyG-SY44/TM4ZD5MuGyI/AAAAAAAADFc/hFlsIT-DcNM/s1600/handbrake+batch+encoder.gif" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="334" src="http://2.bp.blogspot.com/_HXaPyG-SY44/TM4ZD5MuGyI/AAAAAAAADFc/hFlsIT-DcNM/s640/handbrake+batch+encoder.gif" width="640" /></a></div><br />
<i>There is also another solution with lots more options as I just learned, look <a href="http://videoscripts.wordpress.com/">here</a></i><br />
<a name='more'></a><br />
1. you need an external program<br />
get <a href="http://handbrakebatchencode.codeplex.com/releases/view/36793">HandBrake Batch Encoder</a><br />
2. copy the 2 files in your HandBrake directory<br />
3. start HandBrakego to: Tools - Options - Advanced / Other and check "Enable Query Editor tab"<br />
drag and drop one of the files you want to encode into HandBrake<br />
in the Query Editor tab click Generate Query<br />
mark and copy the whole string<br />
it looks like this:<br />
-i "C:\1watch\Cartoon - Bugs Bunny & Wile E Coyote - Operation Rabbit.avi" -t 1 -c 1 -o "C:\Cartoon - Bugs Bunny & Wile E Coyote - Operation Rabbit.mpg.avi" -f mp4 --strict-anamorphic -e x264 -q 25 -a 1 -E faac -6 dpl2 -R Auto -B 128 -D 0.0 -x ref=2:bframes=2:subq=6:mixed-refs=0:weightb=0:8x8dct=0:trellis=0 -v 1<br />
<br />
4. now start the HandBrake Encoder.exe in your HandBrake directory<br />
delete what is in the lowest box and paste the above copied parameters<br />
delete the -i and -o part<br />
it should look now something like that:<br />
-t 1 -c 1 -f mp4 --strict-anamorphic -e x264 -q 25 -a 1 -E faac -6 dpl2 -R Auto -B 128 -D 0.0 -x ref=2:bframes=2:subq=6:mixed-refs=0:weightb=0:8x8dct=0:trellis=0 -v 1<br />
click select Hand Brake CLI and point to the directory where your CLI is<br />
something like that:<br />
C:\Program Files\handbrake beta\HandBrakeCLI.exe<br />
now click Select Folder to Encode<br />
find your folder full of old avi files<br />
DELete the files you do not want encoded<br />
click Select encode location and choose a folder<br />
click Start Batch Encode and enjoy the fine work of HandBrake controlled by buzzby´s batch encoder<br />
<br />
<b>If you try to encode mp4 or other newer formats and nothing shows up in the List Of Files To Be Encoded, then just rename the endings to .avi and it works.<br />
If you have lots of files to rename google for renamer freeware. <br />
There is also an <a href="http://hbencodermark2.codeplex.com/">updated version</a> available what fixes some shortcomings!</b><br />
<br />
Enjoy your much smaller but same quality looking files.<br />
By the way my favorite setting in HandBrake for all normal encodings and re encodings is constant quality RF:25 <br />
I use this from old QVGA VCR files, the HD files from my Sony cameras to BlueRay and are quite happy with the results. If there is something with eye-candy in it, I use the RF:25 in the High profile setting just to be on the safe side.<br />
<br />
This was tested with the newest HandBrake nightly builds svn 3626 and with different encoded files with different sizes and frame rates in one folder.<br />
It worked flawless, the only problem was that the MPG file was not added to the AVI files list and had to be encoded normally in HandBrake.<br />
<br />
To save some clicks , edit the HandBrake Encoder.exe.config and replace<br />
<value>C:\Program Files\HandBrakeCLI\HandBrakeCLI.exe</value><br />
with<br />
<value>C:\Program Files\HandBrake\HandBrakeCLI.exe</value> or where your version is located<br />
and replace<br />
<value>-t 1 -c 1 -f mp4 -X 480 -e x264 -q 20 -a 1 -E faac -6 auto -R Auto -B 96 -D 0 -x cabac=0:ref=2:me=umh:bframes=3:subq=6:8x8dct=0:trellis=0:weightb=0:merange=24 -v 1</value><br />
with the clipped code you put into the bottom box<br />
like<br />
<value>-t 1 -c 1 -f mp4 --strict-anamorphic -e x264 -q 25 -a 1 -E faac -6 dpl2 -R Auto -B 128 -D 0.0 -x ref=2:bframes=2:subq=6:mixed-refs=0:weightb=0:8x8dct=0:trellis=0 -v 1</value>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5899112496273323949.post-81487848056593057472010-07-26T06:24:00.000-07:002010-07-28T06:58:38.674-07:002 pass encoding vs. constant quality encoding<span style="color: orange;">2010.7.28 15.00</span><br />
and why frame grabs are not always reliable when you want to compare quality.<br />
<br />
I tried to grab exactly the same frame every time what proofed to be futile, so this is as close as its get.<br />
Also I made lossless crops from the 1280x720 screen shot in 640 x 640 pixel that you do not need to click on the picture to see the full size. This size is the maximum Blogger can display in the posting. They are re-compressed by Blogger, but I compared the posting images with my originals and they are comparable. <br />
All grabs are done in GOM player.<br />
Just hit F11 now to go full screen in your browser and it is very easy to just scroll up and down to fast compare the results. When you are finished hit F11 again and your browser is back to normal.<br />

you guessed wrong!<br />
<br />
I, II and II are from the same original AVCHD encoding what had a size over 550 MB and a bitrate of 3300 Kbps.<br />
<br />
Bummer!<br />
<br />
So what can we learn about that?<br />
Screen grabs can only tell you so much. If you grab a few frames (a few milliseconds) later, the imperfections might already be fixed and your comparison will be flawed.<br />
So it is best to view the video on the big screen, find the areas what has problems and compare these time frames during normal play back if they bother at all.<br />
<br />
This reminds me a lot of pixel peeping at digital cameras. The final result what you can make from the raw material is what counts.<br />
<br />
<br />
What I learned from this little exercise is: Stick with RF:25 and if I need to really squeeze a video then go to 2 pass encoding.<br />
<br />
---<br />
<br />
Here is a comparison between a 22 min South Park episode<br />
550 MB standard size encoding and a RF:25 encoding what resulted in a 98 MB file.<br />
Both use the same audio compression.<br />

How far can we compress a 21 min cartoon in 720p HD and keep a good quality.<br />
Would you believe me that you can reach a file size from 75 MB and it still looks acceptable?<br />

Since these changes are very fast from light to dark and back, the dark parts get neglected much more than the bright parts which are in much better shape. You have seen the worst parts above and normally your eye might not notice them but in fast moving scenes there are very short small areas of visible compression artifacts.<br />
<br />
So for my personal taste right now I will stay in the RF:25 area (where I do my normal encoding and digital camera video re-encodings) and experiment a bit more with some settings to see what more can be optimized.Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-5899112496273323949.post-35191988980262118302010-07-19T16:15:00.000-07:002010-10-31T18:26:30.396-07:00Shrink your video files<span style="color: #ff6600;">2010-7-19 15.11</span><br />

Well, I don´t know about you, but with the quality the Sony HX5 gives me in videos, I find myself using the video function more and more. And that shows on my disk. Where before a DVD was enough to archive several years of picture memories including some clips, now a DVD would be filled in a matter of weeks.<br />
So I need a way of keeping the videos I want but if I could get them smaller without loss of visible quality that would be perfect.<br />
After spending several days work to try all kinds of programs and fiddle with the settings to get exactly the results the way I wanted it it is time to share that information with you. In one sentence: <i>You can save 50 to 75% of space and keep a good quality.</i><br />
<i> <b><span style="color: #6aa84f;"> </span></b></i><br />
<i><b><span style="color: #6aa84f;">If you have lots of movement over most of the screen, then re-compression might not save you much. This 3 min clip "<a href="http://www.youtube.com/watch?v=LrJc2Vt03Lg">Fiesta del Carmen Gran Canaria 2010 - Sony HX5.MP4</a>" in the original is 150 Mb re-compressed with RF:25 (see below) brought the file down to 132 Mb. In a case like this you already got the best compression / quality ratio in the original file.</span></b></i><br />

<br />
If you have a mostly static scene like on this 32 second clip a <a href="http://www.youtube.com/watch?v=E6pMsghjZCg">small grasshopper drinking</a>, you can archive a compression from the original 24 Mb to 3.3 Mb at setting RF:25 what is quite a lot for nearly the same quality. <br />

Now, how is it possible to compress one file so much and another nearly not at all?<br />
Coming from over 10 years of getting video clips to the computer starting with VHS-C, the Snappy to grab images out of the videos and the DAZZLE with a parallel port to encode to REAL Media with QVGA in the last Millenium we have come a long way and the two pass encoding in AVI is so yesterday.<br />
<br />

<br />
From the HandBrake wiki:<br />
<i>With the average bitrate or target size methods, you control the size of the output file but give up control over the video's quality. </i><br />
<i> </i><br />
<i>Constant quality mode does the opposite; you specify a quality level and HandBrake adjusts the bitrate (that is, the size) to meet it. </i><br />
<i>Because it takes a different bitrate to reach a given quality level for any given part of any movie, the output size is unpredictable and varies from source to source. </i> <br />
<br />
I will show you how you can easy decide what quality YOU like and how you can shrink all your video files quite a bit and always have the same quality.<br />
Before we finally start, here a sample from a <b>HD</b> encoding with the old 2 pass method. If you have extremely fast flashing of pictures during a scene, two pass just can not handle the fast changing amount of information.<br />
The result is a quality like this:<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_HXaPyG-SY44/TERee96mZ7I/AAAAAAAACts/BgeEJdTeuqE/s1600/h264+2+pass.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="360" src="http://4.bp.blogspot.com/_HXaPyG-SY44/TERee96mZ7I/AAAAAAAACts/BgeEJdTeuqE/s640/h264+2+pass.jpg" width="640" /></a></div><br />
In constant quality mode this part of the movie would be as sharp and without noticeable compression artifacts. And this is why you should spread the word about HandBrake and the gorgeous constant quality mode you can use to compress your video files.<br />
<br />
<br />
<br />
First let´s take a short trip to France.<br />
Go visit the makers of Handbrake and get a free <a href="http://handbrake.fr/">copy</a>. You can have it for: Mac OS, Windows, Ubuntu and Fedora 12<br />
<i>If you want to have the newest version from Handbrake, check out the nightly builds.</i><br />
Install and run it. Drag and drop a video file into it.<br />
<br />

<b>Video Filters</b> - If you recorded in AVCHD set <a href="http://trac.handbrake.fr/wiki/Decomb">Decomb</a> to Default. If you recorded in MP4, skip this step.<br />
<b>Video</b> - Now comes the decision how good the quality YOU are desire has to be. The lowest acceptable level for me is RF 32 @ Constant Quality, RF 28 is a good balance for size and quality.<br />
<b>Audio</b> - no change<br />
<b>Presets</b> - Regular Normal<br />

<b>Video Filters</b> - If you recorded in AVCHD set <a href="http://trac.handbrake.fr/wiki/Decomb">Decomb</a> to Default. If you recorded in MP4, skip this step.<br />
<b>Video</b> - Now comes the decision how good the quality YOU are desire has to be. The lowest acceptable level for me is RF 32 @ Constant Quality, RF 28 is a good balance for size and quality. For a nice quality RF 25. If you go up to RF 20 and above, you will have nearly the same size than the original.<br />
<b>Audio</b> - no change<br />
<b>Presets</b> - Regular High Profile This encodes slower but more precise, the file gets a bit bigger also.<br />
<span style="font-weight: bold;">Advanced</span> - for even more precise encoding copy and paste in the bottom box:<br />
ref=6:mixed-refs=1:bframes=3:b-pyramid=1:weightb=1:subq=7:trellis=2:analyse=all:8x8dct=1:no-fast-pskip=1:no-dct-decimate=1:me=umh:merange=64:deblock=-2,-1:direct=auto<br />
<b>Destination</b> - choose where you want to have the re encoded video<br />
press the green <b>Start</b> button<br />
<br />
Let us see how we can get the smallest file size with the quality you want.<br />
<br />
<span style="font-weight: bold;"><span style="font-size: 130%;">Under the Hood</span></span><br />
If you want to do some testing for your self, cut 10 seconds of your favorite video. Take a part where you have a steady object and a part where there is lots of movement. If you do not have that, just grab something quick with your camera. Why only 10 sec? Because it takes a lot of time to encode if you want to test things for yourself.<br />
Here are some of my results:<br />
Since in some parts of our globe a breast and especial an uncovered nipple is a taboo I decided to crop the screen grabs to keep you poor folks sane.<br />
Here is what to look out for:<br />
The compression artifacts will appear first on the painters upper arm, also look at the mesh of her top for compression smearing. The face and the eyes of our model and the contour of the face to the water are an indicator for the sharpness, or loss of.<br />

<b><span style="font-size: large;">Video Compression - Size vs. Quality</span></b><br />
All the tests are done with Handbrake. <br />
For more info see the <a href="http://viconco.blogspot.com/2010/07/shrink-you-video-files.html">Shrink you video files</a> post. <br />
Let us see how we can get the smallest file size with the quality you want.<br />

I did some testing with several blue ray disks.<br />
RF 28 did show some slight problems with compression artifacts in dark areas RF 25 has less.<br />

The Die Hard 132 minutes long movie<br />
with RF 28 @ 482 Kbps encoded and Dolby Pro Logic II @ 160 Kbps resulted for the 720p version in a tiny 611 Mb file. Acceptable quality and a 2 hour 720p movie on a CD size - I am impressed.<br />
As always, click on the pictures for the full size screen grabs.<br />

With this work I have done, it should be pretty easy now for you to have an idea what compression to choose.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5899112496273323949.post-35668905753766669202010-07-08T10:59:00.000-07:002010-07-08T18:30:03.570-07:00AVI - encoding the old wayMy goal was to find an easy to use free software what converts the Canon SX1 monster files into a good quality format what works with low power hardware.<br />
That is a 1,6 MHz notebook with a Centrino Duo 2 GB and a Nvidia GO 7300 XP SP2 and a 1,6 MHz notebook with an AMD Turion X2 1 GB with an ATI XPress 1100 XP SP2<br />
<br />
I liked best so far SUPER it is free, simple and powerful.<br />
Get it <a href="http://www.erightsoft.net/SUPER.htm">here</a>.<br />
<br />
<a name='more'></a><br />
<br />
Drag the video file into the program, choose:<br />
AVI - MPEG-4 - MP3<br />
video setting: No change, 16:9, 30pfs, bitrate 4000<br />
audio setting 44100, 2, 128<br />
CTRL+T to set the path where you want to have your file<br />
hit encode<br />
now you have an AVI file 8% of the original size in full HD with mostly acceptable compression artifacts.<br />
Want to have it in better quality, try 5000-6000 or 8000 if you want it really good.<br />
<br />
I put a couple sample pictures below so you can see for yourself how the compression/quality ratio is.<br />
<br />
Test results<br />
The Centrino Duo 2 GB and a Nvidia GO 7300 XP SP2 had no problem after the conversion with any file to play.<br />
The AMD Turion X2 1 GB with an ATI XPress 1100 XP SP2 had problems with even the 4000 kbps files and required a down sampling to 1280x720 to play the video files smoothly.<br />

Look at the concentric rings in the left circle, you will notice the compression artifacts here the most. As usual click on the pictures for full size. The pictures show only 1280 from the 1920 pixel since they are done via screen capture from my 1280x800 screen.<br />

Welcome to the club.<br />
<br />
On my search for an affordable solution to play full HD files on the big screen I found an interesting gadget.<br />
After learning the hard way that a media player with or without hard disk and a HDMI port does not necessary also plays HD videos I needed to do some research on that topic.<br />
In my case the media player enclosure did not even wanted to touch SVGA (800x600) or anything with a higher resolution. No way to ask for a down sampling or so. Just DVD resolution is the most these units want to play.<br />
<br />

<br />
Visiting the guys at Trusted Reviews I learned about the <a href="http://www.trustedreviews.com/multimedia/review/2008/12/02/Western-Digital-WD-TV-HD-Media-Player/p1">Western Digital WD TV HD Media Player</a> and the <a href="http://www.trustedreviews.com/multimedia/review/2009/06/16/Popcorn-Hour-A110/p1">Popcorn Hour A110</a> and the brand spanking new <a href="http://www.trustedreviews.com/multimedia/review/2009/08/07/Asus-O-Play-HDP-R1-HD-Media-Player/p1">Asus O!Play HDP-R1 HD Media Player</a>.<br />
The <a href="http://www.xtreamer.net/">Xtreamer</a> was mentioned in some comments and after a couple hours on the <a href="http://wdtvhd.com/">WDTV forum</a> and the <a href="http://forum.xtreamer.net/index.php">Xtreamer forum</a> I had and idea what is possible today and what not.<br />
<br />
We have a Media Markt here on our island and I got very confused there a couple days ago trying to understand what is the difference between a just player with a HDMI port and a player with also an HDMI port and a 500 GB hard disk and why the are costing exactly the same, why some have an antenna and others a connection to the ethernet and there are prices from 70 to way over 200 Euros - well you get the idea.<br />
After my homework I decided for the WD TV because the Asus is to new to be here already and the popcorn hour is to exotic to be here. The Xtreamer would be 119 Euro and had to be ordered via mail.<br />
Lucky for me the Media Markt had 3 WD TV just sitting and waiting for me and for 95 Euro I snatched one, another one found a new home just a few minutes later.<br />
<br />
Remember my confusion about these things a couple days ago?<br />
I had nearly purchased a 500 GB or 1 TB SO Speaky HDMI (what a goofy name) from DANE ELEC for 119 or 149 Euros.<br />
Well today when I snatched my WD TV the 1 TB had a new price. 99 Euro - the 500 GB was still at 119 Euro.<br />
For that money I got myself another 1 TB storage with a free basic media player.<br />
Funny thing, I tried to find the codecs or resolution on the box. Nada not even on the small handbook anything.<br />
On the drive is a handbook folder and there it states:<br />

So you see you have to dig deep to find out what these things are capable of.<br />
I tried to find out if anybody tested one of the full HD hybrid cameras on the WD TV, but no luck.<br />
So here for your information the WD TV HD will try to play the original video footage from the SONY HX1, the Canon SX1, the Canon EOS 5D Mark II and the Panasonic GH1 in full HD resolution (video camera full HD in the case of the SONY).<br />
I took the clips you see at: <a href="http://sony-hx1.blogspot.com/2009/08/movie-time-1080p-competition.html">Movie Time - the 1080p competition HX1 vs SX1 vs GH1 vs 5DII</a> and play them one after another in full HD resolution. The video quality on this You Tube clip is not good, but it is just to see how well or not they are playing on the WD TV.<br />
You will find more general info about the cameras and video clips <a href="http://www.cameralabs.com/features/1080p_HD_video_comparison/GH1_vs_5D_Mark_II_vs_SX1_IS_vs_HX1.shtml">here</a> at the Camera Labs website. Also you can download the short clips for yourself on vimeo and compare for yourself.<br />

Result:<br />
The WD TV plays all 4 clips without stutter, it has just a problem with the uncompressed audio format what Canon still thinks it has to use in their videos.<br />
<br />
