AVI files need rendering

I've recently been given the task of preparing six hours of short video clips for a foreign language class learning to use some editing programs, iMovie will not work because of the time it takes to import the clips, but final cut is having a problem too. They are all avi files and it seems no matter what easy setup I use the clips always must be rendered as soon as I bring them down onto the timeline. This is a big frustration for students who are not very familiar with the program. I do have the entire final cut studio 2 at my disposal and I was wondering if there was any conversions I could make in Compressor or any other specific settings I should be using in Final Cut Pro to get this to run more smoothly. When I drop the files down onto the timeline it does ask me if I want to change the settings but when I click OK it still needs to render on the timeline. Any advice is helpful, thank you.

any ideas?
Please offer up more information. The more you give us, the quicker we can offer a real solution instead of playing 20 questions ...
• What EXACTLY is the codec the avi files use?
• What are the compressor settings?
• What are the error messages?
A simpler way to go is if you have access to a PC, use it (with QT pro installed on it) to convert the AVI to a QT mov with the dv/ntsc codec.

Uploading AVI files, need codec

I have a Canon PowerShot camer and make videos using .avi. I just bought the Premiere Elements 11. Befoer I bought the program I made sure that it said it would work with .avi files. When I try to upload an avi it says "This type of file is not supported, or the required codec is not installed".
How do I obain and install the required codec? I have already loaded up all the software that came with the camer, and that software works fine; I assume it already has the required codec. But how can I get Elements to use the codec?

You will find best advice over on the video forum. Most of us here are photographers.

Livetype project file needs rendering???

hello, this may be a dumb question. but i was reading somewhere that livetype project files should play in real time w/o rendering. is this true?? is my 3 gigs of ram not enough for this to happen?? i have my settings on unlimited rt and it will not make it though a full clip w/o stopping to say that it dropped a frame. that actually leads me to another question. there is a check box in that dropped frame window that says " do not show again." should i check that. as long as im not printing to tape w/o rendering a couple dropped frames will not affect me, right?? if this is true i just answered my first question. so any info would be helpful. ive wanted to check that box, but have been unsure.( i am pretty new to FCP studio) thank you.

Play where w/o rendering?
If you mean you can drop the .ipr into FCP w/o rendering a .mov then the answer is yes, although when you drop it in FCP you will need to render it there. The advantage of this is that if you want to make changes to the graphic you make those changes in LT and it updates in the FCP prooject. That's quicker than having to render .mov movies all the time. Of course the change will need to be rendered in FCP regardless.
As far as your other question, personally I always want to know when there are dropped frames. If you want to check the box though that's your choice, lots of folks work that way.

Working with AVI files

Is it possible? My camera renders AVI files. I can import the files fine, but they just show a blank white screen as they play. Is there anything I can do or do I need to get a different camera or software? I'd appreciate any help. Thanks.

Hello Carskill,
your AVI files need to be converted before it's possible to edit them in iMovie. AVI is a so-called container - within that file there can be any one of many codecs used to compress video (the same goes for Quicktime .mov files).
Try opening the file Quicktime and looking at the Movie Info window (cmd + I). It should show what codec was used incompressing the video and according to that you'll need to choose the software for conversion.
One tool that recognizes many AVI files is FFmpegX

For more info on AVI files have a look at Dan Slagles Unofficial iMovie FAQ: Working with DivX and AVI files

Problem Playing AVI Files From Adobe Classroom In A Book

Hiya,
I just bought the Adobe Classroom In A Book for Premiere Pro CS4. However, when I try to run Lesson 1, Premiere Pro appears to be having a cow with the AVI file needed for the project. It tells me that the codec is missing or unavailable. I'm using a MacBook Pro on Leopard and, according to the updater agent, I'm up-to-date. Has anyone tried this book? And run into problems? Any solutions to offer me? This is driving me bonkers!
Please and thank you!

Hm-m, the DV-Type II's *should* play fine in QT. At least they do with QT on my PC. Adobe is usually pretty good at getting their CiaB assets X-platform. Wonder what's going on here. I think that this is the third thread on CiaB assets not playing on a Mac. Odd indeed, and probably just a "mess up" on someone at Adobe Press.
Had similar with a Painter 3.0 book, years ago. The author had to send me 11 CD's before we found one that had the PC files on it. All the rest were Mac-only and she was really pissed at her publishing house. However, she hung in there, and we got it sorted out.

How to fix dropouts in imported AVI files?

I am having audio problems on imported AVIs. Using FCP4, i have imported some 45 min AVI files and rendered them on the FCP timeline. ON a timeline of 7 subclips, the first 4 clips play and the remaining 3 clips are silent, even though all display waveforms.
And there's another problem. Of the first few clips that DO play, there is a choppy dropout happening, like the audio drops one frame every half a second. It's a continuous rough and choppy playback effect on the audio. The video portion of the files is fine.
thx
John

Try converting the AVI files to a QuickTime codec that matches your FCP Sequence settings prior to import. AVI is a wrapper or container the hold A/V content that could have been made from any number of codecs, not all of which work with FCP very well. Chances are that the files you imported are one of those.
Also make sure that the files you import are not on the boot drive (desktop, user's home folder, etc) and that all hard drives have at least 15% of free space available.

No Audio in AVI Files

I'm trying to put all my wife's videos from her Casio Exilim camera into one continuous video, but when I open them in Final Cut there's no audio with them. And there is no audio if I open them up in Quicktime also. We've been adding the videos over a period of a year now, and I know that they have had audio before. I can also take the video clips from my Mac and play them on my Windows computer with Windows Media Player, and the audio plays on it. So I know the audio is still there along with the video clips since it plays on my PC, but why isn't it playing in Final Cut or Quicktime? They are also AVI video clips if that helps.

Your avi files need to be converted to QuickTime in order to work with them in FCE. That may or may not be your audio problem.
You can use MPEG Streamclip, a free utility, for the conversion:
http://www.squared5.com/
Open your avi file in Streamclip and export to QuickTime with the following settings (for standard def dv in the USA):
Compression: Apple DV/DVCPRO - NTSC
Frame Size: 720 x 480
Audio should be AIFF @48kHz.

Can AVI files be made playable on Symbians?

I know you can convert regular AVI format movies to the MP4 format that is natively recognised by the Symbian default video player (Real Player?..). But it'd be so much easier if you could just copy an AVI file as it is and have it be played directly, with no conversion. Is it possible to install some sort of codec that would make this possible, or is there a player that can do this natively (similar to MPlayer on the PC)? Thanks in advance for any replies.
Solved!
Go to Solution.

Look for a piece of software called "core player".
JFTR, "AVI" isn't a codec, it's a container format. It defines how the audio and video are multiplexed into a single file. A device wanting to play back an AVI file needs a demultiplexer to access the encoded audio and video data. Only once it's got at that encoded data does it use a codec to decode it. Many different combinations of audio and video codec can be used to encode data that ends up in an AVI file. This explains why some media players can only play back certain AVI files and not others. Depending on the codec used to encode the audio and video in the AVI file, it can or cannot decode it.

AVIs from AE need rendering in PPro

I'm an AE novice, so this is probably something simple. When I use AVI files from AE compositions in Premiere Pro, they require rendering (have the red line above them even where there are not effects or transitions) while AVIs captured from my camera or generated by Premiere Pro's "Export Movie" do not. A second render is a waste of resources and probably a loss of quality, so I'd like to get things configured so that PPro is happy with my AE-rendered AVIs the way they are.
My PPro project settings are DV NTSC, 29.97 fps, 720x480, pixel aspect ratio 0.9, display format 30fps drop-frame. My AE project settings are Timecode Base: Auto, NTSC: Drop Frame. I'm sure there is simply some setting that isn't matching, but I'm not sure what it would be. A lot of the terms in the Render settings are unfamiliar to me, so I don't know which ones would affect this issue. If it's relevent, the AE project I'm using was originally made in AE 6.0 and recently opened in CS4 and re-edited. Both AVIs that were made in 6.0 and the new one I just made in CS4 do the same thing in PPro (whose version is CS3, if that makes any difference).

Mylenium said:
AE does not support multi-frame temporal compression as required by many compressed formats, so the quaality will often be terrible, and secondly you will not get access to the DV CoDec such as used by Premiere. You may choose Microsoft DV and others, but in essence you'll be back to square one as those will laso require to be rendered/ transcoded in Premiere's timeline.
Sébastien Périer said:
Your workflow is one of the most used between the two apps, but it is
not automatic, you still have to match the 2 aformentionned points.
The impression I got from Mylenium's post was that even if I chose Microsoft DV as the codec, it will still require rendering, and also be lousy quality. I know that there are many "lossless-only" purists out there, but I am satisfied with the normal type of DV compression even for two or three generations, even though it is technically lossy - my final format is MPEG2-DVD, which is much more compressed. But if it didn't do any multi-frame comparison for its compression... Anyway, Mylenium scared me away from even trying to change the output settings, as it sounded like it would not solve my problem at all. But after reading Sébastien's post I decided to try it, and at least at first glance it appears to work fine - the footage goes on the PPro timeline without the red "I need to be rendered" bar, and at least on my screen the quality looks okay to me - I see no visible artifacts. I don't know how to tell if it is doing any frame-to-frame comparison, or how much harm I might be doing to the quality of my final DVD data by doing it this way, but it sure works faster!
...don't be confused with lossy & lossless codecs.
Don't worry, I understand that - a simple example is JPG vs. TIFF, as both compress but TIFF is lossless. But I don't know the subtle differences between different video codecs, and until yesterday I didn't know about the output settings in the render queue pane of AE. (Since everything else I have worked with on this Windows machine has always used Microsoft DV as the codec for AVI's, I was lulled into the assumption that that would be the default in AE as well.) If Mylenium is right that AE's output functionality for that codec is not as clever as that in PPro, perhaps this method will come back to bite me, but meanwhile, it looks like it will improve my workflow tremendously. Perhaps if I re-render my current clips it might even reduce some of my memory problems in PPro - right now, about once an hour or so I get a complaint from PPro about limited memory (or runtime error messages) and have to reboot. [In case you are tempted to ask, I have 2GB of RAM and have my paging file set to a fixed 8GB, but I'm still running out. I don't have that much AE footage yet, but I will be adding more.]
If my current settings (Render Settings: "DV Settings", Output Settings: "Microsoft DV") are not really the same as the normal Microsoft DV that I use for everything else(even though they are accepted as native footage by PPro), please speak up again. I won't delete the lossless versions of the clips (which are about 8 times the size of the DV ones) until I'm sure I won't regret changing my workflow.

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.

Rendering .avi files without increasing size of file

I have 1. a DV/PAl (1.07) 25fps file 733MB sent by client
2. Insert clip rendered as a .mov (the rendering software does not have other options)
I combine the two in AE and render it out as an .avi file that I must return to client at same file size just with the special effect.
PROBLEM:
I render out as an .avi and the file increases to 6Gigs (not joking).
The workaround is to take it into Premier and just reprocess the clip, which works, but adds an extra step.
QUESTION:
Is there a codec that I need that will allow me to avoid taking it into Premiere. If so please be specific. I tried DivX and it crashed AE, so maybe I have the wrong version????
Thanks

Why must the rendered clip have the same file size? That way you will work on a compressed clip that you then recompress again and deliver so that the final output can be compressed again. That's three lossy compressions; guess how the final output will look!
Instead: use lossless compression in the production and only output to a lossy compression format. DV is highly compressed and each recompression will destroy the image quality!
I'd recommend that they deliver a QuickTime PhotoJPEG @100% or a QuickTime Animation @100% (which supports an alpha channel). Alternatively you can use the BlackMagic Decklink QT codecs for 10-bit lossless compression. You can then render back to the same codec and you will not cause any qualityloss during the process.

AVI clips from my digicam need rendering?

Maybe this is a newbie question, I just don't know. My video source is a digicam that produces AVI files. I can bring these into FC Express just fine, I can play them in real time in the Viewer pane. I then drag a clip(s) into the Canvas to create my final video, and when I press Play in the Canvas I get the "Unrendered" message. I'm not applying any effects, just assembling clips. So why can my computer play back the clips fine, but it seems to think it needs to Render before it will play back in the timeline? Thanks.

AVI, or Audio Video Interleave, is an old PC standard for digital video. This file type is no longer officially supported by Microsoft. FCE doesn't work natively with avi files which is why you need to render them.
You'd be better off using a utility like MPEG Streamclip to convert your avi files before you bring them into FCE. Otherwise, you'll be doing LOTS of rendering. Streamclip can be downloaded at

I have AVI files that I need to be MOV files so that I can edit them in Final Cut Pro. I am going to use Quick Time Pro for this....do I have to 'export' it or can I just 'save as', or is there even a difference? Thanks in advance for your help!

I have AVI files that I need to convert to MOV files so that I can edit them in Final Cut Pro. I am going to use Quick Time Pro for this....When I have the files open in QT Pro do I have to 'export' it or can I just 'save as', or is there even a difference? Thanks in advance for your help!

I strongly recommend you use compressor to do the conversion (if it will open the files - since quicktime will open them, it will more than likely do it.
Compressor allows you to customize presets and save them and apply them to multiple files. Although the interface may seem daunting, it's actually pretty simple.
Even if you can edit the avi in fcp, it's not a good idea. Liable to cause problems down the road.
