How do I export a video totally uncompressed without forced Resample of Audio?

I wanted to export my music video uncompressed without the audio being resampled.

Here is the problem - I don't want Magix to resample the audio. When I export the video and audio it wants to resample my already mastered audio from 44.1 to 48kHz. I want to leave the video and audio untouched when I export. How do I do that with Magix. I own both the standard version and the Pro version.

When I use the option to export uncompressed the option to change the audio sample rate back to 44.1kHz is greyed out.

Hi. (Just an "aside" question: are you the same airon as on the Reaper forum? If so, good to meet a fellow-user here, though my post count is far lower than yours!)

First, what is the "destination" of your exported video? If it is to DVD, I'm sure you know that the DVD "standard" for audio is 48kHz. I suspect MEP may be "locked" to this.

Also, why "uncompressed"? Beside the inevitably very large file created, you are right about your existing audio being up-sampled (I've just checked this also in VPX5 and there is no way to choose 44.1 for the audio - the "normal route" to make changes is via the "Advanced" button but this is greyed-out.)

Personally, my route to "solving" this, if I did not want MEP to perform the up-sampling, would be to open the video in Adobe Audition and allow that program to change the sample rate of the audio - it might be necessary to first export the audio from MEP as a wav file. (Not sure whether Reaper offers the same facility?)

. . . . If it is to DVD, I'm sure you know that the DVD "standard" for audio is 48kHz. I suspect MEP may be "locked" to this. . . .

The DVD standard has 2 acceptable sample rates for audio - 48kHz, as Jeff has stated, and also 96kHz depending on the audio codec chosen, BD also has the option for a samplerate of 192kHz.

If you are making a DVD or BD thenyou have no option but to upscale from 44.1kHz .

It does seem very odd to me that you want the video uncompressed - typical file sizes for uncompressed 1080i or 1080p range between 340 - 800 GB per hour of video ,depending on bitrate and fps. Using a lossless compressor it is possible to achieve files approx 1/3 of these sizes.

Unless of course you require this for commercial DV or BD printing or TV broadcast in which case the companies will specify the format required.
