"QuickTime" format allows you to export an H264 with wave audio, but with a single pass conversion.
"H264" format allows you to choose the 2-Pass VBR compression, but force you to use the AAC codec for the audio.
Is there any way to export a video using the H264 codec with a 2-Pass VBR compression, without compressing the audio?
the export will have several uses, first of all I'll need it to show on a computer a high quality master to a client.
To preserve the original video quality, with an H264 2-Pass VBR I need 80 Mbps, with QT single pass (H264 codec) over 120, that's the reason why I'd prefere to use the H264 format. The original audio is a 24 bit 48000 stereo wave and I'd prefere not to reduce it to an AAC 320 Kbps, even because I noticed thant the compression slightly changes the synch (1-2 frames) and for my kind of works that's annoyng.
I red your message about the MXF export, but with this format export there are some paramters, like aspect ratio, that I can't change.
The original aspect ratio is 2.40 (1920x800).
Since it is a DSRL video, I can preserve the original quality even using the QuickTime format, selecting H264 codec, 100% quality, no bitrate limitations, audio wave.
The reason why I'm not satisfied with this solution is that it's a single pass video conversion that creates much bigger files than the 2 pass conversion of the H264 format, even if the final quality is the same.
So, I was looking for a way to have a 2 pass H264 video export, together with a 24 bit audio wave. But it looks like it is not possibile in Premiere...
The better solution I found by now is to separately import the H264 video (created with a 2 pass conversion with Premiere) and a 16 bit wave audio (created in ProTool) into Avidemux and to export from there an MKV without any recompression. It's quite a waste of time, I don't like the MKV container and I have to downsample the audio in ProTools from 24 to 16 bit, but it's still a better compromise than the AAC or the single pass Premiere force me to use...
Yes, after exporting from Adobe I can find others softwares that can convert the video as I like (QuickTime Pro could probably do it) the fact is that I am trying to understand if there's a way to do it within Premiere, to avoid the double encodig.
Since it is a DSRL video
That would be 1920 x 1080 original cropped to 1920 x 800. My recommendation would be to just use the MXF format and accept the attendant black bars. It'll give you all the quality you need at reasonable file sizes. I can suggest a method to lose the black bars and keep the quality, but the file size will go up.
OK, what would be the method to lose the black bars?
So far, the best solution I found is to create an MKV to join the H264 video created with Premiere and the 24 bit wave created with ProTools. I think I'll stick with it, but if you can suggest anything better...
