Canon Decod MXF Files

Postby TheElectricalGuru on Sat Jan 29, 2011 2:37 pm

Hello Everyone,

I am getting a new canon professional camcorder and it has files that are 50 Mbps MPEG 2 /4:2:2 and has MXF file formats. Does anyone know if my Corel Video Studio Pro X3 will be able to support these type of files. I sure hate to have to invest $1,000 dollars just to be able to edit these formats. Any assistance would be so helpful.

Welcome to the forums,

The new 50 or 60fps video frame rates are not correctly recognized by VS. So are you referring to the frame rate, which is the FPS (frames per second) or are you meaning a file size data-rate of 50 Meg?

I wanted to share that I have a Panasonic LUMIX GH1 photo/video mirror-less camera that takes AVCHD 720p at 60fps that VS handles well. This type of recording can create outstanding slow motion video with extremely high quality. Here is a Properties of one of these video clips inserted in the timeline:

Al -- as a matter of both personal and possibly wider interest, can you output in exactly the same format i.e. true 720p AVCHD (as opposed to HDV) at 60 (or rather 59.940) full frames per second? If so, what command do you use in X3?

I will try, but I doubt VS can output at that fps rate. I know that I have tried to output 1080 at 30fps with high bit rates (36Mbps) and it will not do it. I will update after I tried. It converts the 720p at 60fps clips mixed with photos and clips with 1080 30fps with very high bit rates to 1080, 30fps with 17Mbps correctly and perfectly... Al

Have you tried outputting to Blu-Ray mpeg-2, which certainly can have such a bitrate (or at least around 35 Mbps)? If necessary, you would need to prepare a Blu-Ray Folder in whatever burning module you use, then extract the new video from the STREAM sub-folder of the BDMV/BDAV folder.

But if you are trying to output to AVCHD with such a bitrate, it is impossible for two reasons. First, the international standard for AVCHD only allows a maximum VBR of 24 Mbps. Second, VS apparently does not even recognise that, and only allows a maximum of 18 Mbps (the old maximum) -- though somewhere here recently said it could go to 20 Mbps... And if trying to output to HDV, then it has a fixed CBR of 25 Mbps.

guys,
my camera is just released by canon. The specs say it records in 50Mbps MPEG-2 with 4:2:2 Color Sampling. then it says MXF file format. To see the camera search for Canon XF100 HD Professional Camcorder.

I guess what I am asking is can it support the files the new camera I have coming or do I need to buy a higher priced adobe product or green valley product as they support MXF files. The new camera is coming any day and I need to get an editing software and I do have this with my new computer but just don't know if corel videostudio will support the color sampling 4:2:2 and the MPEG-2 format at 50mbps (not frame rate). These new tapeless professional series camcorders from canon have this new format and it seems only high end editing software can support it. I would like to use this if I can but I can't see where it can support this product.

You are asking this very technical question, about a new product's compatibility, on a user-to-user forum. I think you need to contact Corel's technical or customer support.

While the MXF format is said to be open source, it is in fact top of the line and so recent as never to have been even conceived of when X3 was on the drawing boards... So you would have to luck out enormously to expect X3 or other amateur editing packages currently available to accept the format. And Canon itself says that is only editable in what are top of the line (and thus very expensive) editing packages:
The Canon XF Codec is currently compatible with leading software programs widely used within the video production and broadcast industries including those available from Adobe, Apple, Avid, and Grass Valley.

That being said, it will film using that codec, in "hot-swappable Compact Flash cards in either 1080/60i/30p/24p or 720/60p/30p/24p ". But to repeat, the MXF format is so far unknown to amateur software packages of which I am aware, and I have no idea when or if Corel might support it...

I guess the moral of the story is that if you buy a professional camera, you need to buy a professional editing package. I imagine that Canon will provide some software, but as usually it will be pretty basic. It might allow conversion to one of the formats recognised/produced by VS, but then again, that would rather defeat the purpose of buying such a camcorder in the first place, wouldn't it? :roll:

My Panasonic LUMIX GH1 costs probably a tenth of that Canon Professional Camera and it records at even higher 75 Mbps data rates, it is mirror-less (meaning the viewfinder is always live) and it is considerably smaller and lighter than that Canon; but then to each its own. My Panasonic can produce MJPEG at over 50 Mbps, 30fps and VS (.MOV file type) can read it just fine to produce any of its available rendered files. VS may not be professional, but it handles modern high res camera files well, including the wonderfully small and high quality AVCHD files (.MTS file types) with high frame rates and high Mbps.

BTW, I have now checked about whether VS can produce 60 fps 720p files, and the answer is no. It changes the inserted 60fps clip into 30fps... Al

You are ticked off at our answers :?: I told you, we are only users like you. We don't know for sure. We gave you our opinions. I don't know what else you want, except maybe what you want to hear...

Thanks for this idea, and I will try it. I do not own a Blue Ray player, but own WD TV Live media player and and HD TV that both handle high bit rates. I will try this Blue Ray rendering tip. Thanks... Al

Yes that will definitely work. In fact I have a Blu-Ray player (PlayStation 3) and also a Blu-Ray burner, but I still haven't burned any Blu-Ray discs as they are still prohibitively expensive -- and almost impossible to find -- here in New Zealand. So what I do is process my high def video into Blu-Ray folders so that I *can* burn them at some future time. But in the meantime, I play the individual videos in the STREAM sub-folder from an external hard disk drive connected to my PS3. The PS3 cannot play a BDMV folder (though of course can play it when it is on a Blu-Ray disk) but you can navigate to the STREAM folder and play the individual clips, which are entire. Or of course you can extract them and play them individual as well, changing their titles from the usual 0000.mpg to something a bit more informative! :lol: FWIW, the PS3 *can* apparently play a BDAV (hybrid disc/non-copyright) folder, though I have never tried that...
