AVI files and re-rendering

When my source files are .avi files, they are require a lot of time to render in the timeline, and when they are layered against each other, or any other video overlaps them in the timeline, they require re-rendering.
Just curious if there is any way to "convert" them so they behave more like the DV captures which rarely need re-rendering.

Okay, thanks for the tip. As far as using the settings that match my sequence settings, I'm not sure I can do that with the export to DV with QuickTime Player.
The frame size, vid rate, and compressor all match (720 x 480, 29.97 fps, DV/DVPRO-NTSC). However the Data Rate on these new exported DVs is 6.9 MB/sec compared with 3.6 MB/sec on the captures from tape, and the Aud Rate is 32.0 KHz compared to 48.0 KHz.
In the export window of QuickTime Player, I don't have control over too many things, just DV Format, Video Format (NTSC/PAL), Scan Mode, Aspect Ratio, and Audio Format.
The resulting DV files after the export still require rendering on the timeline.

HT3775 i have a movie in a .avi file and when i open the file it attempts to convert and gives me an error message

I have a movie in an .avi file and when i open the file the Mac attempts to covert the file and it doens't play. What can I do?

VLC will play avi's, even if the index is broken. IT can repair most broken avi's but will still play them if it can't.

.avi files and subtitle drag&drop

Is there any video player that can play .avi files and also support drag&drop subtitles? I tried Perian with Quick time and now it plays .avi files perfectly. However still can't drag the subtitles to Quicktime screen. Also I tried Miro and VLC Player. They both lack of 'drag&drop subtitle' function.
I'm new to mac, only 3 days. Maybe there is a trick to do that drag&drop thing. Any help?

use Mplayer from appstore and its free..:)

I have PX90 and trying to play it on my Mac but it's a .avi file and I cant figure this out, help

Trying to play .avi file and I cant figure it out. I am pretty Mac ignorant(hey at least I own one)
I've uploaded a couple files but they stay as .dmg files and I cant get them to work and quicktime
isnt working. I dont think I should have to purchase another so called $29.00 file to make .avi
work on my Mac. Does anybody know what I am doing wrong?
Thanks

AVI is a legacy file container originated by Microsoft back in 1992 and which has not been officially supported for more than a decade. Like the container, many of the codecs commonly used to create AVI content are also "legacy" compression formats most often supported on PC/Windows platforms. In fact, some codecs have never been transcoded for Mac use. Of those that have, many never made the transition to Mac OS X or the transition to Intel-based platforms. Those codecs that are still supported on the Mac can normally be found in the free Perian codec component package available as an online download. While some common AVI compression formats may be supported by the QT X Player app, QT 7 currently provides a more compatible AVI playback environment for most "legacy" compression formats. If the codec(s) used in your AVI files are not supported by the Perian package for QT use, you can try the VLC media player which may still support more esoteric compression formats. If VLC does not support the files, the normal approach is to discover which specific audio and/or video codecs were used to create the file and perform an Internet search to see if a compatible Mac component is available for download.

My QuickTime player us not playing .avi files and says I need a codec I can't play no .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime.

Hmm . . . comes with a Utility MPEG2 Component ML app with no explanation of what it's for?
The utility app is an "assistant PKG installer." It allows Lion and Mountain Lion users to install the older QT MPEG-2 Playback Component installer PKG file which is not allowed to run on its own under Lion or Mountain Lion since these operating systems already have a QT X only MPEG-2 component embedded in the QT embedded structure. Without this utility you would have to either copy the component from an older system to your Lion or Mountain Lion system, use Pacifist for installation, or manually open the PKG contents and transfer the component to the appropriate component folder.
As to your "discussion" regarding the playback of AVI file types, there are really only two strategies here:
1) You can add component support so that QT can play the files natively or
2) You can convert the file contents to compression formats that are natively compatible with the unmodified QT component configuration.
Each user should decide for his or her own self which approach best suits their needs for a particular source file. In most cases, conforming the system's codec component configuration to play the source file directly results in higher video quality since no transcoding takes place but this strategy will not work if a codec which is required is not available for the user's operating system. On the other hand, converter utilities tend to support more built-in codecs and are easier to use since the user does not have to concern him or herself with the nature of the particular source compression formats but at the risk of some potential loss in visual quality. As to what converter to use, once again this is a matter of personal choice. In the case of commercial converters like iSkysoft, the codecs are built in while MPEG Streamclip accesses the host operating system's QT codec component configuration. I personally prefer the free HandBrake app for AVI, MKV, TS, MTS, and M2TS conversions since it has an exceptionally full-featured X.264 GUI with some user options that 97% of users are likely to never use.

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.

Why does my quicktime player verson 10.2 somtimes read avi files and other times it wont recognize them?

Why does my quicktime player version 10.2 sometimes read AVI video and other times it will not recognize that same file. I have a video card that sometimes it will read then the next time it recognizes the card but will not open the video. Message says "quicktime does not recognize this file.
Whats up with that ??? Any help will be most appreciated!

AVI is a container just like MKV, WMV, MOV, and MPEG. It is possible to use many different compression formats aka. codecs in an AVI container.
Think of the container - AVI as being an envelope, and the compressed video in it as a letter. The letter may be in a language you cannot read even though you know how to open the envelope.
Historically QuickTime did have some built-in ability to use AVI files and some formats in those files, this used to be further improved by installing the free Perian (for Mac only). However with Mavericks Apple have removed the ability for QuickTime X aka. QuickTime Player 10 to use AVI files, it now really only accepts MPEG4 or H.264.
It is still possible to install QuickTime 7.6.6 in Mavericks and if you use it and Perian rather than QuickTime X you can still use various AVI files.
Note: Mavericks also now no longer shows previews or thumbnails for AVI files for the same reason.

.avi files and codecs

Hi I posted a question yesterday about .avi and there were some helpful responses. I installed GSpot and it tells me that the CODEC for the video file is MJPG/Motion JPEG, on an Olympus Pen EPL1 digital camera, and there is no CODEC required on the audio file. It then says that the MJPG CODEC is installed on my computer, so why when I import the file into Premiere Elements 9, it plays back in very poor quality?
Regards

Poor playback, when the proper CODEC is installed on one's system is often due to a mis-match between the Source Files, and the Project's Preset. The biggest killer of Quality, is when the Frame Size of the Project does not match the Frame Size of the Source Files, and Scaling is done, with Scale to Default Frame Size checked.
The next most common cause of a lack in quality is the specific CODEC itself. For MJPEG, there are two highly popular CODEC's, Morgan and MainConcept. While there are others, those two are highly recommended by many users. Many cameras, that shoot in MJPEG will also ship with the mfgr's. version of the MJPEG CODEC. As that mfgr. might well have tweaked things a bit, if one does have a utility/driver disc, I would strongly recommend installing their version of MJPEG. This might be installed along wiith the driver for the camera, as part of an editing/organizing program, or maybe as a separate install. It will just depend on the camera, and might even vary, model to model. This ARTICLE will give more background, and also some potentially useful links.
Let's go back to the first paragraph. When you ran your Source Files through G-Spot, what were the Frame Size and PAR (Pixel Aspect Ratio) listed?
How do those figures match up with your Project Preset, chosen with New Project? A mis-match here can have a very negative effect on quality. If one has Scale to Default Frame Size checked, and the Source Footage is smaller, than the Project's Frame Size, the user will not see that the program has Scaled UP the Clip(s) to match. If Scale to Default Frame Size is unchecked, then the user would see black bars around all, or parts of the Frame, with the Clip displayed smaller in the Frame.
While PrE can Scale footage UP, or DOWN, its algorithms are not the best and quality will suffer. A little bit of Scaling might go unnoticed, but if one had, say SD 720 x 480 material, in an HD 1920 x 1080 Project, then quality would go down dramatically.
One thing to consider is that if there is a mis-match, there will be a red line over the Clip(s). This shows that for the best, smoothest playback, that footage needs to be Rendered. One would press Enter to Render that Timeline. The Render could be limited to just a segment of the Timeline by using the WAB (Work Area Bar). This produces proxy files, that will give the best possible playback. This ARTICLE will give more background on Rendering. While the Program Monitor in the program, on a high-rez computer monitor is not the best viewing situation for SD material (an NTSC, or PAL, calibrated CRT monitor is the best, but those are very expensive, and the NLE program needs to support them), one can get fairly close by adjusting the Magnification (Rt-click on the Program Monitor) to 100% from Fit. To see the entire Frame, it might be necessary to adjust the Program Monitor's Panel.
As you can see, there are several things that can affect quality. If you will give us info on your Source Footage, your Project's Preset and also which version of the MJPEG CODEC, someone will be able to direct you.
Good luck, and thanks for the info.

Import 2 avi files and combine in 1 dvd

Hi En experts!
I have installed the Encore Cs5 Trial with Win7 64bit.
Now i will import 2 avi files (part 1 and part 2 for a video) and combine in sequence and after write a dvd for my tv-dvd player..is possible? Give me please instructions...
Thank's and sorry for my poor english !
Ciao from Italy!

With two separate Assets, I would recommend doing one separate Timeline for each one, as this can circumvent some issues, when one gangs Assets onto one Timeline. If you need continuous play for multiple Timelines, then just use Playlists and you can choose to play any/all Timeline(s), and in any order desired.
Even with separate Timelines, one can still use Chapter Markers and can then use Chapter Playlists to access those as desired.
Make sure that you do NOT use any Overrides anywhere - use Playlists, or Chapter Playlists instead.
Happy authoring,
Hunt

.avi files and 'ms' format audio

Hi Folks,
I have QuickTime 7 Pro and a .avi file I was sent (actually downloaded on FTP). I also have a host of other video players (MPlayer OS X 2, VLC, RealPlayer 10) All of them can play the .avi file but I get no audio. If I choose "Show movie properties" in QuickTime it lists the audio as 'ms' format. Is there any way to get QuickTime, or any other video player, to play the sound on this file?
Hope someone can help me with this.
Cheers,
Grant

any suggestions for the same problem but for OS X (10.3.9)?
You'll have to find out what codec was used for the movies you want to view to determine what you need. Note that not all codecs for the various .avi movies are available for QuickTime.
If you want to try "hit and miss", you can try the codecs at http://www.divx.com/ and http://www.3ivx.com/ and see if one of them will work for you. If you just want to play the movie any way you can, you can also give this player a try:

Avi files and Quicktime

Hello everybody...
so I did a search on the subject and tried everything mentioned, but still came up with no results.
I have some avi files on a CD that I would like to view and then burn onto a DVD as a movie file. I tried to open them with Quicktime 7 to no avail. I downloaded DivX Doctor as well as DivX Fusion Beta, which was recommended in other posts. Still nothing. Do I need to download real player? And if so, will I be able to burn the avi files onto a DVD for viewing on a regular DVD player?
Any help on this matter would be greatly appreciated. Thanks in advance!
Nicholas

The format I see is WMV3, 720 x 480
There is your problem. That is a closed Microsoft format. The Mac version of the MS Media Player may let you play them. See http://www.microsoft.com/windows/windowsmedia/software/Macintosh/osx/default.asp x
However, it only lists WMV7, WMV8, WMV9 and WMVP as supported - no mention of WMV3

HT204382 i have a dvd disk with a few movies on it but they are AVI files and are not playing, does anyone know how i can resolve this problem?

hi, i have a macbook and have been trying to play a dvd disk i have with some movies on them. well besically they wont play as theyre AVI files, does anyone know how i can solve this problem?

You can download and install MPlayerX free from Apple App Store. Works great for AVI and other movie formats. I had issues with some AVI's and MPlayerX resolved them.

HT2305 just downloaded quicktime player, tried to play avi file and all I had was a black screen. HELP!

I'm just after attempting to play an avi file with Quicktime player on windows7 and all I got was a blank screen. Is there any particular reason that this is happening, or is quicktime incapable of playing avi files without going pro?

The QuickTime Player doesn't have the right codec for that specific AVI. Purchasing QuickTime Pro will make no difference; it doesn't contain any additional codecs.

.avi files and Final Cut

When I try to import an .avi file Final Cut says .avi files are not optimal and I need to recapture the footage - but all I need is to import an already edited .avi file from my desktop to Final Cut, if it supports .avi files why can't I import them?

.avi is a wrapper and not a codec.
We need to know what codec you use.
If you don't know, open it with QuickTime and then get the info.
