AVI to QT movie conversion size difference

I was trying to convert an AVI that is 33MB large into a QT file using the h.264 codec. I was suprised when the resulting video was 108.6mb large. Is this normal? Is the QT file supposed to be that much larger than the original source AVI? I viewed them side by side and the quality of each is identical.

data rate automaticThis is your problem. If you compare the total average data rates of your source and target files, you will find the target file is roughly 325% that of your source file. In order to create a smaller file, you must restrict your data rate. Try converting a 30-second to 3 minute test clip with a video data rate more on the order of 1200-1500 Kbps and an audio data rate of 64 Kbps per channel at 44.1 KHz. Check to see if quality is acceptable and adjust settings as needed until the trade off of quality for file size suits your requirements/tastes.

Artifacts in Using Save As for AVI to MOV Conversion?

When I SAVE AS a compressed avi file to mov, I am seeing artifacts (they look like interlacing errors) in the final mov file, vs the same frames in the .avi file. Can I avoid this somehow? The avi file was compressed with the BlackMagic Intensity code (I think it's motion jpg too).
The file sizes are the same.
Bummer, I bought Quicktime Pro just for this. Any help appreciated.
Thanks

Can anyone here tell me why two duplicate laptops treat the avi-to-mov conversion so differently and why I must export at 480p?
As to QT playback, either the codec component configuration is different on each system or the the AVI file contains a legacy video codec that is turned on for system "A" but left off for system "B" but which is included in the Perian bundle installed on system "B." With reguard to the forced conversion rather than a simple "Save As..." action, please confirm the video codec name given in the "Inspector" window for each system. I suspect that either the video codec is different on each system or that the Perian version of the same codec with a different name may be forcing the "Export" conversion.

Mpeg streamclip avi to mov conversion settings for Final Cut Pro

Some help please.
I have just started to attempt to edit some avi files on the latest FCP, and for one reason or another, I'm having trouble converting the AVI files to MOV files in Streamlip, I have tried quite a few variations, but with very little joy. When i try to import a recently created MOV file into my FCP project, it either has no audio or both video and audio need rendering once placed on the timeline.
When I try to play the created MOV on QuickTime, again, there is no sound.
I was just wondering if someone would be kind enough to tell me the exact Streamclip AVI -> MOV settings they have used to combat this problem, or simply just tell me where I'm going wrong.
Hugely appreciated.

Hi again,
I have spent the last few hours trying all different types of variations of conversion, but with no lukc.
Thanks for the tutorial link, but the problem isn't that I don't understand how to use Streamclip. i just don't know which video and audio settings to use to create a .MOV file that will provide me with audio. This seems to be my major problem so far. Audio isn't even present when I view the .MOV clip in quicktime.
I have tried DV - PAL, H.264, Apple Motion Jpeg A, Apple DVCPRO - PAL etc etc, none with any success. It may be the way I'm trying to compress the audio, but I'm pretty sure that I've now tried everything!
I simply need to know a good conversion and compression setting that will at the very least allow me to play the video with audio in QT. once I have that, I don't mind rendering the audio in FCP as it takes no time at all to do.
Cheers!

Avi to Mov conversion software for Mac

Since I can't search I may be asking a redundant question, but can anyone help me with locating some software for the Mac that will help me to convert some .avi files to .mov?
Thanks,
Jim

i think quicktime pro will do that.
unless it's some obscure, windows encoded avi file...
i like to use iSquint which is a free, slimmer version of Visual Hub...
--it's meant for getting just about anything on the iPod... but the settings allow you to choose pretty much whatever you want...

P.Pro 1.5 - Losing quality in AVI/MPEG to DVD conversion

Hi, everyone.
Is my first time in Adobe forums and my english isn't certainly the best, so excuse me for something I'll possibly make wrong :-)
This is my problem:
I edit a lot of videos (holidays, weddings, karting, ...) from Mini-DV tapes. No problem on edit work, neither on export to AVI or MPEG. And at this point (after export) I don't think I had lost some video quality or if had that would be slight. But when I finished the next step (convert the resulting file to DVD format) I realize that video suffers from a substantial quality lost, mainly a distortion on whites (they get much brighter and, of course, lose some of its texture). Also, not always, is noticeable a kind of yellow and red thin lines along the "objects" shape (mainly on human faces).
At first I thought that was noting about Premiere and all about the conversion from AVI/MPEG to DVD because it's when the problem occurs, but after I had experimented all kind of converting software and the problem happens all times (sometimes more, sometimes less), I become to think the problem may be in Premiere exporting settings.
So, these are my Premiere exporting settings:
Export to AVI: File -> Export -> Movie
Some important settings:

I also thought the problem could be on the hardware but a few months ago I made an upgrade on my computer and changed CPU, Motherboard, RAM and Graphics card (had an AMD Sempron 2800+, 2 GB DDR and an ATI 9600 Pro 128MB) and the problem still remains...
Actually I think it match all the needs:
CPU: DualCore Intel Core 2 Duo E6300
Motherboard: ASRock 4CoreDual-Sata2 (chipset: VIA Apollo PT880 Pro)
RAM: 2x 1GB DDR2
Graphics card: Asus EAH2600 512MB
Windows XP Pro with SP2
I don't care about time CPU will spend to do the task - before the upgrade it tooks aprox. 5 hours to convert a video and now it tooks only 1h30m :-). What is really important is obtaining the most quality DVD video can be possible. Can you help me?
Perhaps someone already asked for something like my problem. If so, please excuse me and give me the link to that question.
Many thanks to all of you in advance.

Dag Norum:
First of all, thank you for your quicly reply ;-)
Second, I'm very sorry to make a reply almost a month after your answer. The reason is that I went on holidays without an opportunity to test your tip.
I used Harm's link and than reached to a Bitrate of 8.0000 for all three fields (Min., Target and Max.) and that makes all the difference. Now I have a video with very good quality.
But I haven't tested your tip yet to see if that improves the video final quality.
I want to work always with the maximum quality, no matter what time is needed to convert the video and no matter the length (GB) it costs.
Do you think I can export to an uncompressed file (avi for windows and compressor set to none) and than make the Menus with Encore? It wouldn't be better work on Encore with an MPEG2 file? The DV compressor is MPEG2, isn´t it?
And why you suggested to not have the "Optimize stills" checked? This is to optimize the frames without movement, isn´t it? Many times I use photos inserted in the movie. This option isn't good for that?
Your last suggestion, to go directly from timeline to the end target (MPEG2) is much different than that I use (DV compressor)?
If you could answer my questions I would appreciate.
Many thanks!
(sorry if my english isn't the better)

Sorry, I'd made a mistake. When I answer to you I didn't realise that your sugestions was to AVI exportation and not to MPEG2.
Of course you are absolutely right: for an intermediate file, no compression is always better than some compression :-)
But my question about not have the "Optimize stills" checked remains. What does it makes, really?

Problem Converting AVI (DV) to MOV (DV)

I have a number of AVI (DV) files that were previously imported on my PC, which I want to covert (using my Mac) to the more Mac friendly MOV (DV) file format.
I read that the best way to achieve this is to open the AVI files in Quicktime Pro and to convert the files to MOV using “SAVE AS”, as opposed to “EXPORT”. I understand that the benefit of using “SAVE AS” is that there is no recompression of the DV stream and that only the Container is changed (which results in a lossless conversion).
The problem is that the new MOV (DV) file is significantly larger than the original AVI (DV) file. For example, the size of a 13.5 minute clip increases from 2.95 GB to 5.88 GB.
I wouldn't expect such a significant change in file size if only the Container is indeed being changed.
I have also tried MPEG Streamclip to do the conversion, but I get the following message when I try to open the AVI (DV) file “File open error: this movie file is not supported”.
I have confirmed using Gspot that the AVI (DV) file is a 'Type 1' as opposed to a 'Type 2' file. Gspot also indicates the following information about the file “Multipart OpenDML AVL (3 parts). I don’t know if this is relevant.
Any advice would be greatly appreciated.

UPDATE PROBLEM SOLVED:
I was able to fix this problem by following a reply that I received on forum.videohelp.com. Basically, I was able to fix the problem by using a program called DVdate to convert my AVI (DV) files from Type 1 to Type 2. Now all is well. Here is the link below to the answer.

How do I export to AVI. file and make the size smaller?

Looking to export a film as a AVI file and alter the size and quality.
Thanks!

Hi,
you can use QT or FCP>Export> QT movie conversion but I like using Compressor.
In Compressor settings tab there's a button with a plus icon on the top right corner. Click it and in the popdown menu choose Quicktime Export Components.
You've just created a new untitled setting. It sits at the bottom of the settings in the untitled folder.
Drag and drop it onto your movie file just imported in Compressor. Double click it and/or see it in the inspector window. Give it a name and in the encoder type choose AVI.
Now (still in in the inspector window) if you click Options button below you can change a number of settings. Remember, the higher the bit rate the better the video will look but greater wil be the size of the video.
Do some tests to find best settings.
An example to use just as reference:
a 3GB DVCPRO HD video becomes 400MB AVI at 1000kbyts
Hope that helps,
G.

I recently purchased QuickTime 7 Pro to convert avi files to mov files for editing on Imovie. However, QuickTime won't play the files. How can I get them to play and how can I convert them to mov files?

Both the AVI and the MOV file extensions refer to the file container and not the compressed data the file contains. Both are generic file containers in that each may contain any valid combination of audio and/or video data that is compatible with the codec component configuration of the system on which the file was created. On the other hand, whether a file is playback compatible, conversion compatible, and/or edit compatible depends on the data actually contained in the file container. So, you are basically dealing with two separate issues here—the container and what is inside it.
Basically, if you want to make your files ediit compatible with iMovie, you must change your file container to one that is acceptable to iMovie and convert the data to edit compatible audio and/or video compression formats as may be necessary. The best approach is to determine what codecs were actually used to create the original AVI files and add them to your system if possible. In most cases a codec package like Perian can be added to your system's codec component configuration to may the AVI file playable. Once they are playable, in the QT 7 app then they can be chnged or converted to file types and compression formats that can be edited in iMovie. (While Perian handles most codecs commonly used to create AVI files, it does not handle all possibilities and, while the Perian codec package still works under cureent Mac OS versions, its development group has decided to drop further development/support of the package.)
Background: AVI is a file container originally developed by Microsoft back in 1992 but for which official support was discontinued about 11 years. Despite its limitations, Windows users still tend to use this file based on its open source ease of use and generic nature, thus, making its use so popular that most users are unwilling to switch to more modern but less generic file types. Since some AVI legacy compression formats have never been transcoded for the Mac or use beyond OS 9 or OS X PPC platforms, it is often important to know what specific compression formats are contained in the AVI file to know which codecs to add to your system and which not to add in order to avoid possible codec conflicts.
You can use many different converters to convert AVI files to iMovie edit compatible files. Most third-party apps contain their own buit-in codecs which do not relay on the Mac codec component configuration. Free ones, like HandBrake, usually have limited conversion capabilities while those that have more varied outputs are usually commercial in nature and will cost you additional cash. QT 7 Pro or the free MPEG Streamclip app allow you to access you own system's component configuration and use any available codec component like DV, AIC, MPEG-4, H.264, Photo JPEG, etc.—all of which are iMovie compatible for editing purposes—but only after making the AVI file QT 7 player compatible.
In order to determine what compression formats wewre used in your AVI files you can
1) Try checking the Finder "Info" window,
2) Use the "Inspector", "Media Info", or "Properties" window of any player app that will open the file, or
3) Use a general media utility app like "MediaInfo" to read the file characteristics.

Quick Time Pro - Problem Exporting AVI files to .mov

Hi all, Here is the problem that has been plaguing me and driving me crazy. hopefully somebody can help me with this.
I use pinnacle studio 8 to create the avi file, the resulting file size is 1.02GB. Everything works fine in this file audio and video
Next I use quicktime pro to convert the file to a .mov format and compress the video down. This is where the problem starts. when I try and export the avi to a .mov, the options screen doesn't allow me to select the audio, it says its not there. I can modify all the settings for the video, but it doesn't even recognize the audio.
It has been doing this for all of my avi videos that are over a gig. It also does this when I try and export an mpeg to a .mov
also if I do go ahead and export to a .mov file, it compresses the videos down to around 5 to 7mb, where as all my videos that are exported to .mov that do have sound are roughly 20+mb
Anybody know whats going on? I'm going nuts trying to figure this out.
Message was edited by: tlsolutions

Sounds like your AVI isn't really a two track file (audio and video) but rather a muxed MPEG-1 file.
QuickTime Pro can't extract audio from muxed file formats and that is why it shows no sound options during export.
MPEG Streamclip (free) can export MPEG-1 to QuickTime formats and extract the audio.

SQL Server replication and size differences of source and destination databases

I set up snapshot replication for a DB between two SQL instances. On the source instance, the DB shows as 106612.56MB with 34663.75MB as available free space. I expected that the replica would then end up being 71948.81MB (106612.56 - 34663.75
because it wouldn't replicate the white space). The resultant replica database is showing as 35522.94MB. The required data appears to be present in the replicated DB as the SSRS reports that use it are able to find the data they look for. But
why the large discrepancy in size between the source and replicated DB? The replicated DB is less than 1/2 the size of the source DB. I've searched around and can't seem to find any explanation. I realize this isn't mirroring so the DBs will
not be identical in size but I did not expect to see such a large difference between the two. I am replicating all almost all articles (tables, stored procs, etc.) with the exception of a handful of stored procedures and user-defined functions that either
reference invalid column names in a table (vendor bug) or reference another DB that is not present on the replica's instance. I would expect these 4-5 articles can not account for a 37000 MB size difference between the two DBs.
Please note that this has nothing to do with transaction log size. I am specifically talking about the database size and am not looking at the size that combines both DB and TxLog size.
Any insight?

Another factor could be that on the publisher the data is distributed through pages, paragraphs and extents. Depending on your fill factor and the amount of deletes and your datatype, there could be space in the pages, paragraphs and extents which have not
been reclaimed.
During the bcp process which is part of the snapshot application process on the subscriber all the data will be in the tables in a contiguous fashion. I would suspect this would be why you have the difference in space usage.

Font Size Difference between Exe and Labview IDE

I'm stumped on the following issue and surprizinglycan't find any references that are similar on this forum.
I've developed an application which, when built to an Exe, has different font sizes than when executed on the same computer in the Labview Integrated Development Environment. In each instance the screen resolution is the same. I've used the "Application Font". I'm having trouble figuring why the font would render differently in each case. Of possible signifigance is that I'm running the Exe by simply browsing to the folder where the build procedure drops it instead of building an installation.
I've attached one of the most glaring examples that shows the rendering in each case.
I'm hoping that someone can point me in the right direction to resolve this issue.

Hi Doctor,
two notes:
for the font size differences: I would try to change the font settings
to a more 'specific' font like Arial 14pt. The application font is set
somewhere in an ini-file and the setting may change with the
environment (IDE vs. exe-rt).
for your attachment: please convert pictures to jpg or png. This will
reduce size by orders of magnitude :-) And please crop them, unless you
have a very (VERY) beautiful desktop background picture!

Converted .avi files to .mov in quicktime, can't transfer to ipod.

so i recently converted .avi files to .mov using perian in quicktime. i imported them into itunes, and they play just fine there. unfortunately, they won't load onto my ipod. i get an error that the format is not recognized by my ipod. has anyone had this issue? if so, am i doing something wrong, and/or how can i correct this? i'm using a 2 ghz powerpc g5, and a 160 gb ipod classic. thanks!

You need to convert to MPEG-4.

Avi, mpeg and mov problems

I`m having no luck playing streamed .avi, mpg and .mov ( all video) files.
The avi and mpeg video files freeze up upon start up and only show the first second of the video for the first 5-10 minutes. After that they play fine although with no sound. They also play and sound fine after being downloaded and then opened.
The mov files only show the sliding bar or , after being saved , the blank QT screen with the bar sliding and no sound.
Also , the QT "intro" on apple.com/quicktime (the timberlake video) refuses to play properly, it just comes in very "blocky" with only occasional sound bits getting through. The same can be said about some avi files, when they do work.
I have flip4mac , divix, 3vix, xvid installed. Tried perian but that completely killed all streaming avi playback , just a Q with ? mark. Downloaded AC3 codec and put in the QT folder. no luck.
These are the sites in question.
http://www.justintimberlake.com/QuickTime/justintimberlakeqt.html
http://www.geocities.com/Heartland/Prairie/1568/videos/riki_discovers.mov
Couldn`t find any avi movies to use as an example.
Last question. Is there a way to automaticaly stream avi and mpg files in the same QT screen as wmv and asf files?
thank you and sorry about the long post.
imac intel core2duo Mac OS X (10.4.8)

Try VLC media player regarding playing .avi files.
===============
I had no problems playing the Timberlake video. However, when I tried to play your second link (.mov) all I got was the bar, no audio or video.
Regarding your 1st link, have you tried repairing permissions & restarting?
Regarding your 2nd link: Apparently, it's a bad video link & no fault of yours or your computer.
====================
"Is there a way to automaticaly stream avi and mpg files in the same QT screen as wmv and asf files?"
The following is a work-around for .avi files. Not sure if it will also work for .mpg files.
Open the file with QuickTime Player.
Open the Movie Info window (Command-i).
Note the name of the video codec used in the file.
Do a Google.com search for codec name +Mac and download one appropriate for your OS and computer.
Quit and relaunch QuickTime after installing the new codec.
Try the file again.
Thanks to QuickTimeKirk for the above info.
================
Regarding no audio sometimes................
If repairing permissions does not work, then try the following:
KB article - No sound from some applications, but system alert sounds play (Mac OS X 10.3, 10.4)
Another trick: If you have GarageBand installed, open it and then quit.

File size difference between DNG Converter and Lightroom Beta 4

Hi,
I want to go the all-DNG route and am trying several things ATM. I want my files to be as small as possible, thus I disable previews and RAW embedding and enable compression in DNG Converter. In Lightroom, there are no options at all. What I do get, are pretty amazing file size differences:
Original .NEF as it came from my D70s: ~5MB
.DNG created by DNG Converter: ~1MB
.DNG created by Lightroom: ~4MB
The very small file size in DNG Converter is the one that bother's me most. I get these small files from time to time. I checked both the DNG and the NEF in Photoshop, and they seem to be identical. So my question is: What triggers these small file sizes? Do I loose anything? Or is the Lightroom DNG converter not as advanced as the stand alone version?
Maybe this helps: I get the ridicolous small files for very dull subjects that tell the computer scientist in me that it should be easily compressable by common compression algorithms.
Thanks for any pointers,
Markus

Thanks for the hint! It did make me revisit those files and now I see the reason for the small file sizes: The Apple Finder does note update the file size view once a file was added to a folder. Here's what I did:
Opened a folder full of .NEFs in detail view in Finder.
Converted them using DNG Converter
Looked at the sizes of the files as they were shown in the Finder window allready open.
Unfortunately, those file sizes are not correct. If I open a new Finder window of the same folder, file sizes are correctly reported as between 3.5 and 5 MB.
