You can use Streamclip (free program) to convert mp4 files to Quicktime with Avid DV codec. This happens pretty quickly. just make sure you set it to 420 for PAL or 411 for NTSC.

Then import the Quicktimes into the Avid. That happens even quicker!

hmm

i know that these are mp4 files.

Okay, well chances are then that the MP4 file does not contain any Avid-standard video (DV25/DVCPRO/DNxHD etc...)

It's likely that the file is an H264 or MPEG-4 compressed file. In this case conversion will have to take place upon import into Avid, and such a step is normal.

Just remember though that if you end up in the future working with other files, not all of them will require a conversion process upon import to Avid.

Oh, and since I'm in a bit of a hurry, could you let us know what the project type is that you're working with? PAL/NTSC? Progressive/Interlaced?

Also, what format are the files you are trying to import? Where did they originally come from?

Cheers.

it's says it's making audio from QT & then making video from QT.

why is it "making"? it's already in the file.

i went to the setting into the media link & i saw that it is on "DV" so i set it to 1:1 which is no

compression...

If your source material is already DV, there's nothing really to be gained by importing as 1:1. In the import dialog set the Video resolution to match your DV file (DV 25 420 for PAL DV material - or DV 25 411 for NTSC DV and PAL DVCPRO25)

Choose options and make sure frame size is for 601/709 non-square along with 601/709 for the colour levels. Last thing to set is lower-field (Even lines) for the fields.

If your file is an appropriate DV-resolution file, it will "Fast Import" purely as an OMF/MXF rewrap without any additional compressing.

Whenever you're working with standard DV material, you should never see "Making Video" at all. I certainly haven't. It's all down to the correct import settings.

Also, as far as I'm aware, 1:1 is 4:2:2 sampling, so if you have PAL (4:2:0) or NTSC (4:1:1) it stands to reason that whilst 1:1 is very high quality and virtually lossless, there'll be conversion occuring at least on a colour sampling level.

"Fast Importing" a standard DV file is actually more like a true 1:1 import because it's simply a copying process of the source file into an OMF/MXF container. What Avid then accesses really is a 100% copy of the original. (As far as I can logically work out.)

Any file you import into the Avid needs to be re-wrapped into an MXF (or OMF depending on your preference) file for use in the application.

why it's taking soooo long to import files to a bin?

is it encoding the files?!?

it's says it's making audio from QT & then making video from QT.

why is it "making"? it's already in the file.

i went to the setting into the media link & i saw that it is on "DV" so i set it to 1:1 which is no

compression but still it takes ages to import. how could i just import it & let it use the file without

avid to "make" audio & video from scrach.

thanks
