Hi i just got a camera that seems to only shoot in AVI and am trying to import in fcpx....Tried using the file converter in VLC to convert....

Could you review why you are converting it in the first place? Will FCPX not import the AVI file directly?

If the codec within your AVI files is H264, then some utility might rewrap those which would be faster than transcoding. I initially thought EditReady would do that, but I guess not.

Here is a brief tutorial on codecs and container formats:

Thanks again everybody.

The video initially wouldnt import to FCP unless converted.

However, I tried Remux and this allows me to rewrap the files to mp4 and it works great now, no lag loading it.

The only issue i've noticed is that when i first click on a location in the timeline, it sometimes flashes wierd pixels for a fraction of a second, which ive never seen any other cameras do. Doesnt affect anything to me bc it happens so fast. Any idea why this is happening?

is this anything to be concerned about? Since i'm not having any issues with laggy camera files now, is it safe to proceed using this camera in the future, or are these files maybe more likely to get corrupted or something like that? I would like to keep the camera bc i got a good deal on it and seems to be working well now, but i just want to make sure that i wouldnt be setting myself up for more issues in the future (especially considering how much people seem to dislike using avi files here). Given that it seems to be working well, and I can convert them (and nobody else will be editing these files), is there any need/reason to get a different camera now?

Anybody have any advice about this? I'm about to invest in some more cameras and am thinking about getting more of these avi cameras , but i want to make sure that i wont be making a mistake in the long run by doing so. (compared to the other cameras i'm looking at, they are cheaper and come with a remote which is helpful)

rethink that ;)

as now mentioned several times from several experienced board members:
avi is some stone-old, obsolete, in its beginning Microsoft-only, now not more supported even by MS itself media-wrapper …

Plus, what's of more interest - what does it wrap? standard-conform codecs? or 'something', causing funny flashes, relaxing greens, happy dots, wotever …

No idea, which super-cheap toy you like to purchase at some arcane Alibaba shop ;) ..... but a 2017 cam utilising avi for real video recording? no way.
I'm using <50€ devices too - my 'sacrifice cams' placed inside soccer-goals - some mov, some mp4, but avi? Nope. Not even as a gift!

Avoid AVI at all costs! Because of what Karsten said, old, out of date, low quality codec, and just bad idea.

These are good questions and you are smart to be asking them. Weird pixel flashes at the start of a clip could indicate the file header or first GOP (Group Of Pictures) was not edited or transcoded correctly. This is often seen in utilities which purport to extract clips from long GOP formats without transcoding. As you said, the questions arise: is this a big deal, or is it some little cosmetic glitch. Will it cause problems down the line in future versions of editing software? Unfortunately it is impossible to say.

In the past (before FCPX) I have used utilities like those to expedite sub-clip extraction and it often caused problems down the line.

If you stay with this camera and AVI material you should probably do further testing. E.g, how does the "pixel flash" clip behave when played with VLC? What about when played on a Windows machine?

There are ways to print out keyframes or do some integrity checking in the video file using the command-line ffprobe utility, but I haven't done that. If you pursue that, you are stepping down another level and will then be investigating how the utility works, what certain error messages mean, etc.

It would be interesting how and whether Resolve or Premiere Pro handles that AVI content. You can download a free evaluation copy of Premiere and Resolve is also free. So here you see the dilemma: how much time is it worth investigating these anomalies and at what point are you confident it is OK.

Sometimes the camera manufacturer will have a utility for importing or transcoding content. You could also make inquiries about that.

....I don't know why it does that. Your info indicates 1080p H264 within an AVI wrapper. In general I suggest using EditReady: www.divergentmedia.com/editready...

It can re-wrap much faster than transcoding methods -- just select "rewrap" as the method, since it can also transcode. Since you plan on using this camera a lot in the future that will come in handy. They have a free trial you can examine. I use EditReady frequently on AVCHD and older AVI material.

I have about 60 hours of .avi media from 2000 to 2007. I actually have EditReady 1.4.9 which is the latest update. I cannot open and/or drag .avi files into it. In fact, all my .avi media is grayed out when trying to do so. If there's a way to re-wrap the.avi in EditReady, I'd like to know how. I do realize that FCPX will ingest it natively but, like most here, I would like to re-wrap it to .mov first.
My other problem with my .avi is I don't know what codec it is since it's all in clip form without that info. Thanks, Ray

My previous statement was wrong. EditReady will not rewrap AVI. However I understand your older AVI content is standard def DV. IMO this does not require rewrapping or transcoding since the codec is simple and the resolution low. There is no performance or quality benefit to rewrapping or transcoding this. You will likely not need to generate either proxy or optimized media for these files -- they can be imported with "leave files in place".

Just be advised that DV is typically interlaced, so you'll need to use a progressive project and set "deinterlace" in the Inspector for each DV AVI clip. FCPX will not deinterlace DV content from an NTSC project, because by definition there's no such thing as deinterlaced NTSC. If you use a progressive project and forget to set the deinterlace checkbox in the Inspector, it will discard every other scan line and you'll lose resolution. But DV in a progressive project with deinterlace enabled will export and look OK.

DV also generally uses a 4:3 aspect ratio so it will be pillar boxed in a 16:9 progressive project. There are various ways to deal with that.

The most important content to rewrap is AVCHD, and IMO it's mandatory for bare .MTS or .M2TS files. Not rewrapping those can cause I/O performance problems because of how FCPX handles those files.

depends.
Microsoft had it sown breed of DV, socalled DV-1 = which wasn't compatible to nothing; if this is the case, simple rewrapping doesn't work.

and btmk, DV-1 was never avail on MacOS, not even in any converter tool… 'dv in an avi container' = I smell danger :)

First, I thank you for taking the time in describing why and what I need to do.

Yes, my .avi is interlaced and I will copy/save your instructions for FCPX. Just a few settings but, very important ones.

Yes, it's all 4:3 aspect ratio. I will need to find/experiment with using it in a 16:9 progressive project. With me being new to FCPX, if there is a couple simple tricks, please share them if you wish.

I do have an enormous amount of M2T files in which I'm using EditReady. As you know, this software is straight forward....... and did I mention, it's awesome.
I'd like to add, I'm coming from Sony Vegas Pro and DVDA therefore, fingers crossed, I'll be up and running in a short time. I do have Ripple's Core Training, Media Management, Sound and Color Correction training which will help tremendously.
Thanks again for all your help, I sincerely appreciate it. Ray

Ok....... I was just playing around with moving .AVI files. Here's what I discovered;
1) Right mouse to play a. .AVI file.
2) Choose Quicktime and a popup comes up "Quicktime Can't Open"

Now here's the interesting part;
1) I open up my Movies folder in Finder.
2) Drag and drop a .AVI file from an external drive into it.
3) Right mouse on the .AVI file.
4) Choose Quicktime
5) It accepts the .AVI and automatically converts it to .MOV and asks if you want to save it or not.

As a Newbie..... This was an awesome find!!! My only question is to those of you that have converted this way is;
Have you noticed any quality loss ? Thanks, Ray :)

The Quicktime conversion is supposed to preserve the original quality of the file. I have used this on rare occasions and have found the file quality of the mov to be an acceptable match to the original when played on a PC.

Thanks for the help and link..... If it enlarges the video slightly, I'm sure there will be a little quality loss. I may just import the .AVI directly into FCPX. Thanks again, Ray

It would not enlarge the video (in the sense of scaling it to a bigger frame size), it is referring to creating a larger file size during it's processing to a Prores flavor. This is no different than optimizing media in FCPX which creates a less processor intensive file at the expense of a larger file size. Either way, if you can successfully import the AVI into FCPX directly, that is the method I would use. You may find you'll need to optimize it upon import for best playback anyway, depending on what codec is inside the AVI container.

Yes, it will import into FCPX natively without any issues. In addition, it plays back fine inside FCPX as well. I'll just deal with it within FCPX as you suggested instead of trying to convert it to .mov ahead of time. Thanks for all your help, I sincerely appreciate it. Ray ;)
