Need to make a mp4 of the hi-def edit. Settings question
on Jan 15, 2014 at 6:25:28 pm

Hi,
I am shooting weddings in 1920x1080 29.97 and want to give my clients the best quality mp4 file on a flash drive for them to watch on their computers or plug into tv.
I use the vimeo HD preset @ 5mbps and have been increasing target and max bitrate to 25 mbps; render at maximum quality and depth. Is this best way or overkill? For 2.5 hour edit the mp4 file can be 35 to 40 gb. What about audio? Should i change sample rate at 48000 if for computer or tv?
I want to give best quality and avoid any artifacting issues during dancing or camera panning.

2) How do I get the file to be recognized if plugged directly into the tv or a blu ray usb port? I format flash drive as EXFAT to work on PC as well as Apple.

3) Is there anyway to embed chapters into a mp4 file - either before output or afterwards?

Thanks
Wayne

Increasing the target bitrate is overkill.

That vimeo HD preset works great, make sure it is 2-pass vbr
and check the "maximum quality" button.

You might consider using the 720P preset as this will be
a much smaller file size with the difference in real world
visual quality being negligible if barely noticed than 1080.
Also 720P plays smoother on a lot more systems that may
be older.

if you feel 5mbps is not enough, take it to 10mbps, but
anything more is over kill and I've done tons of these
over the years. You can also reduce the file by changing audio from
48khz to 32khz with no noticeable quality loss.

2) exfat would work on a pc and mac, but most blu-ray players
including the ps3 only read fat32 volumes. Authored DVD or Blu-Ray
discs are probably more practical here.

3) I don't believe its possible to embed chapters in .mp4 files.

Good advice from Chris. However, I would recommend NOT checking the box for "Max Bit Depth" though - that only applies when working with high bit-depth sources like 10-bit video, which I doubt you are using.

Also, my understanding of the "Max Render Quality" button is that it's purpose is for SCALING of the video, for instance 1080 to 720, or HD to SD. If going from a 1080 source to 1080 output, then I don't think it's doing anything, other than increasing render times. Whenever you see checkboxes anywhere in Premiere that are NOT checked by default, that means they are for special situations. If they were always needed/beneficial, they would be on by default ;-)

The "Max Bit Depth" I'm very confident about. "Max Render" I've seen differing info, but general consensus says not needed if not scaling.

Thanks
